Description

The present invention relates to a control device for an environmental equipment control system .

BACKGROUND ART Conventionally, in order to increase work efficiency of workers, it has been required to improve the environment in the space where workers exist.

For example, in the control device for an air conditioner described in Patent Document 1 (Japanese Patent Application Laid-Open No. 10-259943), while grasping the arousal level of the subject, the arousal level is naturally reduced from a state in which the arousal level is lowered such as a dozing state. It proposes to keep the working efficiency of people in the room high by executing the air conditioning operation to shift to a high state.

In the device described in Patent Document 1, by detecting the degree of inclination and shaking of the subject's head with an image processing circuit, it is possible to grasp that the subject is falling asleep, etc., and wake up the subject. In order to increase the temperature, we will control the air conditioner.

However, in the apparatus described in Patent Document 1, the target person falls asleep or the like due to the surrounding environment of the target person, and the subject's head tilts or starts to shake. The air conditioner is being controlled to raise the temperature. For this reason, when the control of the air conditioner for raising the awakening degree is started, there are cases where the object's state such as the awakening degree has already deteriorated considerably.

In addition to stimuli caused by environmental factors such as temperature and humidity that can be controlled by air conditioners, the causes of such changes in subject's arousal level are stimuli caused by environmental factors that are not controlled by air conditioners. However, no study has been made so far on controlling the subject's condition by paying attention to such environmental factors that are not controlled by the air conditioner. On the other hand, it is desirable to suppress the influence on the subject due to receiving an unintended environmental stimulus from the outside.

A control device for environment control means according to a first aspect is a control device for environment control means for controlling the environment of a target space in which a target person exists using environment control means, comprising: an environmental stimulus grasping unit; And prepare. The environmental stimulus grasping unit grasps a second environmental stimulus, which is an environmental stimulus received by the subject and is an environmental stimulus other than the first environmental stimulus controlled by the environmental control means. The control unit controls the environment control means so as to cancel or moderate the influence of the second environmental stimulus grasped by the environmental stimulus grasping unit on the subject.

Here, the environmental stimulation that can be controlled by the environmental control means is not particularly limited, and for example, at least one or more selected from temperature, humidity, wind speed, odor, sound, light, radiant heat, and combinations thereof. can be

The second environmental stimulus is not particularly limited, and includes, for example, stimuli related to temperature, humidity, odor, sound, light, vibration, and combinations thereof. Here, the stimulus related to sound is not particularly limited. It also includes the stimulus that the subject receives when an excessively quiet situation below the specified volume continues for a predetermined period of time or longer. The second environmental stimulus is an environmental stimulus other than the first environmental stimulus controlled by the environmental control means, and is the same type of stimulus as the first environmental stimulus if it is not caused by the control of the environmental control means. However, it is preferable that the stimulus is of a different type from the first environmental stimulus.

In addition, the control of the environmental control means for canceling or softening the influence of the second environmental stimulus on the subject is not particularly limited, and for example, removing or reducing the cause of the second environmental stimulus. control to reduce the subject's sensitivity to the second environmental stimulus; the subject's psychological response to the second environmental stimulus and/or the psychoneurotic response that is the response in the autonomic nervous system and combinations of these controls.

In the control device of this environment control means, the environmental stimulus unintentionally received by the subject is controlled by using the environment control means used to control the environment of the target space, thereby reducing the influence of the subject on the subject. can be counteracted or mitigated. Therefore, it is possible to suppress the influence of environmental stimuli that the subject unintentionally receives on the subject.

A control device for environment control means according to the second aspect is the control device for environment control means according to the first aspect, wherein a plurality of types of environment control means are provided. A plurality of types of environmental control means can supply different types of environmental stimuli. The control section controls the plurality of types of environmental control means so as to cancel or moderate the influence of the second environmental stimulus grasped by the environmental stimulus grasping section on the subject.

In this environment control means controller, a plurality of types of environment control means can be used to counteract or moderate the effects of the second environmental stimulus on the subject. For this reason, it becomes easy to cancel or moderate the influence of the stimulus unintentionally received on the subject.

A control device for environment control means according to a third aspect is the control device for environment control means according to the first or second aspect, wherein the plurality of types of environment control means include a device for adjusting temperature and a device for adjusting humidity. At least two or more of a device, a device for adjusting wind speed, a device for adjusting carbon dioxide concentration, a device for adjusting odor, a device for adjusting sound, a device for adjusting light, and a device for adjusting radiant heat.

The control device of this environment control means includes a device for adjusting temperature, a device for adjusting humidity, a device for adjusting wind speed, a device for adjusting carbon dioxide concentration, a device for adjusting odor, a device for adjusting sound, and a device for adjusting light. By performing control using at least two or more of a device for controlling radiation heat and a device for adjusting radiant heat, it is possible to reduce the influence of stimuli that the subject unintentionally receives on the subject.

A control device for environment control means according to a fourth aspect is the control device for environment control means according to any one of the first to third aspects, further comprising a state information grasping unit. The state information grasping unit grasps state information regarding the subject's state. The control unit controls the environment control means so as to cancel or moderate the influence of the changes other than those caused by the control of the environment control means on the subject among the changes in the state information.

Here, the state information includes psychosomatic state information and biological state information. Of these, the psychosomatic state information is secondary information inferred from primary information (heartbeat, etc.) obtained by measuring the subject. Information such as an index of autonomic nerve balance is included. Biological condition information is primary information obtained by measuring a subject using a measuring device, and includes information such as heartbeat, body temperature, amount of perspiration, and voice, for example. In addition, although the degree of arousal is not particularly limited, for example, it may be determined based on the state of the subject's heartbeat, or it may be determined based on the number of times the subject breathes per unit time. may be determined based on the subject's electroencephalogram, or may be determined based on a combination of these.

Even if the environmental stimulus grasping unit in the control device of the environment control means grasps the second environmental stimulus, the subject's mental and physical condition and biological state do not necessarily change significantly, and the subject does not care. Sometimes it's just a little stimulation.

On the other hand, in the control device of the environment control means, the state information grasping section grasps the subject's state information such as psychosomatic state information and biological state information. Then, the control unit controls the environment control means so as to cancel out or moderate the influence of the changes other than the changes caused by the control of the environment control means among the changes in the state information grasped by the state information grasping unit. . Therefore, when the environmental stimulus grasping unit grasps the second environmental stimulus, it is possible to reduce the stimulus that actually changes the subject's mental and physical condition and biological state.

As will be described later, the environmental facility control device 100 receives detection data from the external stimulus sensor 30 to grasp the external stimulus currently being received by the subject in the room, and receives electrocardiogram waveform data from the biosensor 40. By doing so, the arousal level of the subject is estimated, and if the arousal level of the subject is adversely affected by an external stimulus, the air conditioner 10 and the lighting device 20, which are various environmental facilities, are arranged to cancel or weaken the adverse effect. It is a device that controls

(2) Configuration of environmental facility control device 100 FIG. 2 shows a functional block configuration diagram of the environmental facility control device 100. As shown in FIG.

It is configured to be able to receive electrocardiogram waveform data transmitted from 40 .

The data received by the data reception unit 50 can be referred to by each unit of the environmental facility control device 100 .

(2-2) grasping unit 60
The comprehension unit 60 has an external stimulus comprehension unit 61, a current arousal level comprehension unit 62, and the like, and is composed of one or more CPUs, RAMs, and the like.

The external stimulus grasping unit 61 grasps detection data of the odor sensor 31 and detection data of the sound sensor 32 which the data reception unit 50 receives from the external stimulus sensor 30 . In other words, the external stimulus grasping unit 61 grasps the current odor and sound data in the room detected by the odor sensor 31 and the sound sensor 32 .

Based on the detection contents of the subject's electrocardiogram waveform sensor 41 received by the data reception unit 50 from the biosensor 40, the current arousal level grasping unit 62 compares the electrocardiogram arousal level comparison data unit 71 stored in the storage unit 70 to be described later. By taking into consideration the current arousal level of the subject. The current arousal level grasping unit 62 stores the grasped current arousal level of the subject in an arousal level history data unit 72 of the storage unit 70, which will be described later, as history data of the arousal level.

The storage unit 70 has an electrocardiogram arousal comparison data unit 71, an arousal history data unit 72, an external stimulus determination criterion data unit 73, an arousal change determination criterion data unit 74, an external stimulus cancellation correspondence data unit 75, and the like. , one or more ROMs and RAMs.

The electrocardiogram arousal level comparison data section 71 pre-stores data for grasping the arousal level estimated from the detection contents of the electrocardiogram waveform sensor 41 in the biosensor 40, as described above. The relationship between the electrocardiogram waveform and the arousal level is determined based on known matters. For example, by identifying the arousal level corresponding to the electrocardiogram waveform grasped by the electrocardiogram waveform sensor 41 with reference to pre-stored relationship data between the electrocardiogram waveform and the arousal level, the arousal level of the subject is grasped. You may do so.

The wakefulness history data section 72 stores history data of the subject's wakefulness. As described above, the arousal level history data unit 72 stores the current arousal level of the subject ascertained by the current arousal level comprehending unit 62 sequentially, thereby obtaining a history of arousal levels. Data is stored.

The external stimulus determination criteria data section 73 stores information that serves as a determination standard used in determining a predetermined external stimulus level condition for performing cancellation control, which will be described later. In this way, by setting the external stimulus degree condition, among the external stimuli grasped by the external stimulus grasping unit 61, the stimulus with a small degree is judged not to satisfy the external stimulus degree condition, and cancellation control is performed. I try not to

The awakening degree change judgment reference data section 74 stores information that serves as a judgment reference used in judgment of a predetermined awakening degree change degree condition for performing cancellation control, which will be described later. In this way, by providing the target person's arousal level change degree condition, when the change in the object person's arousal level is small, it is determined that the arousal level change degree condition is not satisfied, and canceling control is performed. I try not to

The external stimulus cancellation correspondence data section 75 stores information on environmental facilities used in cancellation control for suppressing the influence of the subject in association with each type of external stimulus. In this embodiment, when it is assumed that the subject is being stimulated by sound, the temperature control using the air conditioner 10 of the environmental equipment is performed to cancel the control, and the subject is odor-related. When it is assumed that a stimulus is received, it is stored that cancellation control is performed by illuminance control using the lighting device 20 of the environmental equipment. Further, in the external stimulus cancellation correspondence data section 75, in the case where the cancellation control is performed by the temperature control using the air conditioner 10, the amount of increase in the awakening level per unit time at the time when the external stimulus degree condition is satisfied is stored. The greater the value, the greater the range of change in the set temperature in the air conditioner 10 (for example, in a situation where the air conditioner 10 is performing heating operation, when the subject is likely to be excessively awakened by a relatively loud noise) ), the relationship between the amount of increase in wakefulness per unit time and the change range of the set temperature is stored. Similarly, in the external stimulus cancellation correspondence data section 75, in the case where the cancellation control is performed by the illuminance control using the lighting device 20, the amount of increase in the arousal level per unit time at the time when the external stimulus level condition is satisfied is stored. The greater the value, the greater the range of change in the set illuminance in the lighting device 20 (for example, the greater the range of decrease in the set illuminance when the subject is likely to be excessively awakened by a relatively strong odor). The relationship between the amount of increase in degree per unit time and the amount of decrease in the set illuminance is stored.

(2-4) Control identification unit 80
The control specifying unit 80 specifies the specific content of cancellation control based on the data stored in the external stimulus cancellation corresponding data unit 75 of the storage unit 70, and uses one or more CPUs, RAMs, etc. It is configured with

(2-5) Control execution unit 90
The control execution unit 90 executes the cancellation control specified by the control specification unit 80 as described above, and is composed of one or a plurality of CPUs, RAMs, and the like. Specifically, the control execution unit 90 transmits the content of the cancellation control specified by the control specifying unit 80 to the air conditioner 10 and the lighting device 20 that are the environmental facilities of the environmental facility control system 1. , the air conditioner 10 and the lighting device 20 are caused to perform the cancellation control.

(3) Processing by environmental facility control device 100 FIG. 3 shows a flow chart of processing by the environmental facility control device 100 .

Here, by satisfying the cancellation control start condition from the state before the cancellation control is performed, that is, from the state where the air conditioner 10 and the lighting device 20 are controlled at the set temperature and the set illuminance, respectively, That is, a case will be described in which canceling control is started by satisfying both the external stimulus level condition and the arousal level change level condition.

In step S10, the control specifying unit 80 determines whether or not the external stimulus degree condition is satisfied. Specifically, whether or not the current concentration and volume of odorous components grasped by the external stimulus grasping unit 61 satisfies the external stimulus degree condition stored in the external stimulus judgment criteria data unit 73 is determined. First, it is determined whether or not the concentration of the odorous component is equal to or higher than a predetermined concentration and whether or not the sound volume is equal to or higher than a predetermined value. Here, when it is assumed that the subject is receiving a large external stimulus because the concentration of the odor component is equal to or greater than a predetermined value or the volume is equal to or greater than a predetermined value, the external stimulus degree condition is satisfied. It will be judged that Here, when it is determined that the external stimulation degree condition is satisfied, the process proceeds to step S11. In this manner, the state in which the air conditioner 10 and the lighting device 20 are controlled at their respective set temperature and set illuminance is continued until it is determined that the external stimulation degree condition is satisfied.

In step S11, the control specifying unit 80 determines whether or not the subject's arousal level satisfies the arousal level change degree condition. Specifically, the control specifying unit 80 first refers to the history data of the subject's arousal level stored in the arousal level history data unit 72, so that the subject receives a large external stimulus in step S10. The amount of change in the subject's arousal level per unit time (in this embodiment, the amount of increase in the arousal level per unit time) at the point in time when it is assumed that the target person's arousal level is assumed to be present is grasped. Then, whether or not the ascertained amount of increase in the arousal level per unit time satisfies the arousal level change degree condition stored in the arousal level change judgment reference data section 74 is determined. It is determined whether or not the amount of increase per unit time is equal to or greater than a predetermined value. Here, when the grasped amount of increase in the wakefulness per unit time is equal to or greater than a predetermined value, it is determined that the wakefulness change degree condition is satisfied. Here, if it is determined that the degree of change in wakefulness condition is satisfied, the process proceeds to step S12. If it is determined that the wakefulness change degree condition is not satisfied, the process returns to step S10 to continue the state in which the air conditioner 10 and the lighting device 20 are controlled at their respective set temperature and set illuminance.

In step S<b>12 , the control specifying unit 80 specifies specific contents of cancellation control based on the data stored in the external stimulus cancellation corresponding data unit 75 . Specifically, the control specifying unit 80 refers to the data stored in the external stimulus cancellation correspondence data unit 75, and according to the type of external stimulus that satisfies the external stimulus degree condition in step S10, Identify the type of environmental equipment to be used in the cancellation control. That is, in step S10, when the external stimulus degree condition is satisfied by the sound volume being equal to or higher than a predetermined value, the air conditioner 10 is specified as the environmental equipment used in the cancellation control, and the concentration of the odor component is equal to or higher than the predetermined concentration. When the external stimulus degree condition is satisfied, the lighting device 20 is specified as the environmental equipment used in the cancellation control. Then, the control specifying unit 80 refers to the data stored in the external stimulus cancellation correspondence data unit 75, thereby determining the air conditioning system corresponding to the amount of increase in the awakening level per unit time at the time when the external stimulus degree condition is satisfied. The increase width of the set temperature in the device 10 or the decrease width of the set illuminance in the lighting device 20 is specified as the content of cancellation control. When the specific content of the cancellation control is specified as described above, the process proceeds to step S13.

In step S13, the control execution unit 90 transmits the content of the cancellation control specified by the control specifying unit 80 to the air conditioner 10 and the lighting device 20, which are the environmental facilities of the environmental facility control system 1. The cancellation control is executed in the air conditioner 10 and the lighting device 20 .

In step S14, the control execution unit 90 determines whether or not the external stimulus level condition satisfied in step S10 is no longer satisfied. That is, in step S10, if the external stimulus level condition is satisfied by the concentration of the odorous component becoming equal to or higher than the predetermined concentration, it is determined whether or not the concentration of the odorous component is less than the predetermined concentration. If the external stimulus degree condition is satisfied by the sound volume being equal to or greater than the predetermined value, it is determined whether or not the sound volume is less than the predetermined value. Here, if the external stimulus degree condition is no longer satisfied, the process proceeds to step S15. If the external stimulus degree condition is still satisfied, the cancellation control is continued.

In step S15, the control execution unit 90 terminates the canceling control and restarts the control of the air conditioner 10 and the lighting device 20 according to the set temperature and the set illuminance before the canceling control is performed.

(4) Features of the embodiment (4-1)
If the change is related to an environmental stimulus that can be controlled by the environmental equipment provided in the environmental equipment control system, the environment desired by the subject can be realized by controlling the environmental equipment. For example, the air conditioner 10 performs air conditioning control so that the indoor temperature reaches the set temperature, but the indoor temperature unintentionally rises, and the subject receives an unintended environmental stimulus. However, control is performed so that the air conditioner 10 maintains the room temperature at the set temperature. Further, for example, the lighting device 20 is controlled so that the illuminance in the room becomes the set illuminance. Even then, the lighting device 20 is controlled to maintain the indoor illuminance at the set illuminance. In this way, even if a change occurs in the environmental stimulus that can be controlled by the environmental facility included in the environmental facility control system, the environmental facility can control the environment so as to eliminate the change in the environmental stimulus.

On the other hand, if an unintended external stimulus, which is a stimulus other than the environmental stimulus that can be controlled by the environmental facility provided in the environmental facility control system 1, occurs, the environmental facility is controlled to eliminate the environmental stimulus. It is impossible to control the environment. For this reason, the target person present in the room will be in an excessively tense state or irritated state due to the unintended external stimulus, and the degree of alertness will be excessively increased (become in a state of hyperarousal). inconvenience can occur.

On the other hand, the environmental equipment control device 100 of the present embodiment provides stimulation other than the temperature change stimulation by the air conditioner 10 and the illuminance change stimulation by the lighting device 20, which are the environmental equipment provided in the environmental equipment control system 1. Even if an unintended external stimulus (in the above example, a stimulus due to sound or smell) occurs, canceling control such as changing the set temperature of the air conditioner 10 or changing the set illuminance of the lighting device 20 can be performed. , suppresses a decrease in concentration due to an excessive increase in the arousal level of the subject.

In this way, even if the external stimulus itself cannot be eliminated by controlling the environmental equipment, it is possible to suppress the increase in the level of arousal caused by the external stimulus. Even if there is, it is possible to maintain the work efficiency of the subject at a high level by preventing the subject from becoming overly aroused and thereby avoiding a decrease in concentration.

(4-2)
The environmental facility control device 100 of the present embodiment includes a plurality of types of environmental facilities (the air conditioning device 10 and the lighting device 20) in the environmental facility control system 1, and the type of stimulus assumed to be received by the subject. Accordingly, canceling control is performed by controlling a predetermined type of environmental facility that can efficiently suppress the influence of the stimulus.

For this reason, it is possible to suppress the extent to which the subject's arousal level changes due to an external stimulus to a smaller extent than in the case where only one type of environmental equipment is provided.

(4-3)
The environmental facility control device 100 of the present embodiment does not execute cancellation control for all the external stimuli grasped by the external stimulus grasping unit 61, but the degree of the external stimulus grasped by the external stimulus grasping unit 61 is about the external stimulus. Cancellation control can be executed only when the conditions are satisfied. For this reason, it is possible to minimize the situation where the temperature and illuminance deviate from the set temperature and set illuminance due to excessive cancellation control.

Furthermore, even when the degree of the external stimulus grasped by the external stimulus grasping unit 61 satisfies the condition of the degree of external stimulus, the environmental facility control device 100 may cause the subject's arousal to actually increase excessively due to the external stimulus. If it is not the case (if the arousal level change degree condition is not satisfied), the canceling control is not executed. Therefore, by performing canceling control only when it is necessary for the subject, it is possible to further reduce the situation where the temperature and illuminance deviate from the set temperature and illuminance.

(4-4)
The environmental facility control device 100 of the present embodiment satisfies the external stimulus level condition and the awakening level change level condition to start canceling control. By adjusting, it is possible to start canceling control before the subject's arousal level rises excessively. This makes it possible to prevent the subject's arousal level from excessively increasing.

(5) Modification (5-1) Modification A
In the environmental equipment control device 100 of the above embodiment, the current awakening level grasping unit 62 grasps the subject's arousal level, and the awakening level history data unit 72 stores the history data of the awakening level. The case where the determination is made possible and the cancellation control is performed only when the arousal level change degree condition is satisfied has been described as an example.

However, for example, in the environmental equipment control device 100, when the degree of external stimulation grasped by the external stimulation grasping unit 61 satisfies a predetermined external stimulation degree condition without grasping the subject's arousal level, the subject By estimating that the arousal level of the subject should be excessively increased and controlling the air conditioning device 10 and the lighting device 20 according to the degree of external stimulation, the excessive increase in the arousal level of the subject is prevented. You may make it suppress.

In this case, for example, in the external stimulus cancellation corresponding data section 75, the volume and settings are set such that the greater the volume recognized by the external stimulus comprehension section 61, the greater the range of increase in the set temperature in the air conditioner 10. The relation with the temperature rise width is stored, and the odor is determined so that the larger the concentration of the odor component grasped by the external stimulus grasping unit 61, the larger the decrease width of the set illuminance in the lighting device 20. The relationship between the concentration of the component and the decrease width of the set illuminance may be stored.

(5-2) Modification B
In the environment facility control device 100 of the above embodiment, the arousal level of the subject is adjusted to an appropriate arousal level in order to avoid an excessive increase in the arousal level of the subject (become in a state of hyperarousal) due to an unintended external stimulus. A case has been described as an example in which canceling control is performed in order to lower the target person's concentration, thereby suppressing a decrease in work efficiency due to a decrease in concentration due to hyperarousal.

On the other hand, the environmental equipment control device 100 not only performs canceling control for lowering the subject's arousal level and shifting to an appropriate arousal level state, but also performs an external stimulus when the subject's arousal level is lowered. Cancellation control may be performed to increase the degree of arousal so that the degree of arousal is appropriate. In addition, both the control for raising the arousal level and the control for lowering the arousal level are included in the canceling control for shifting to an appropriate arousal level, and the control is selected according to the state of the arousal level of the subject. may be executed.

For example, when the subject's arousal level decreases due to an external stimulus, canceling control for increasing the arousal level to an appropriate level of arousal can be used as described below.

FIG. 4 shows an example of a schematic configuration diagram of the entire environmental facility control system 1a in which the environmental facility control device 100 according to this modification is used.

In the environmental facility control system 1a, instead of the external stimulus sensor 30 provided with the odor sensor 31 and the sound sensor 32 in the environmental facility control system 1 of the above-described embodiment, a vibration sensor 33 is used. Device 20 is not included as a control target.

Such an environmental facility control system 1a can be used, for example, when environmental control is performed with the internal space of a vehicle such as an automobile or train as a target space. In this case, the environmental equipment control device 100 recognizes the vibration caused by the movement of the vehicle as an external stimulus. In order to suppress the decrease in the arousal level of the person, it is possible to execute canceling control to increase the arousal level. Here, the schematic configuration of the environmental facility control device 100 itself and the schematic flow of the cancellation control are substantially the same as those shown in FIGS.

The air conditioner 10 in the environmental equipment control system 1a is installed in a vehicle and is capable of controlling the temperature inside the vehicle.

The vibration sensor 33 provided in the external stimulus sensor 30 is attached to the vehicle, detects vibration caused by the movement of the vehicle, and always transmits the vibration to the data reception unit 50 of the environmental equipment control device 100 .

Based on the vehicle vibration data received by the data receiving unit 50 from the external stimulus sensor 30, the external stimulus grasping unit 61 of the environmental equipment control device 100 determines the magnitude of the vibration occurring in the vehicle and the periodicity of the vibration. The drowsiness induction degree is grasped according to a predetermined rule. The drowsiness-inducing degree is not particularly limited, and is determined according to a predetermined rule so that, for example, vibration within a predetermined range that is neither too large nor too small is perceived as a high value as it occurs with periodicity. can grasp.

Further, as in the above-described embodiment, the current awakening level grasping unit 62 of the environmental equipment control device 100 stores the electrocardiogram waveform data of the subject riding in the vehicle, which is received by the data receiving unit 50 from the biosensor 40, into the storage unit Based on the information stored in the electrocardiogram arousal level comparison data part 71 of 70, the current arousal level of the target person riding in the vehicle is grasped at any time and stored in the arousal level history data part 72. - 特許庁

(5-6) Modification F
In the above-described embodiment, the case where the subject's arousal level is estimated based on the detection contents of the electrocardiogram waveform sensor 41 as the biosensor 40 and used to determine the arousal level change degree condition has been described as an example.

On the other hand, the index for judging a change in the subject's state caused by an external stimulus is not limited to the degree of arousal. It may be information.

Among these, the psychosomatic state information is secondary information estimated from primary information such as heartbeat obtained by measuring the subject, for example, alertness, concentration, tension, rest, LF/HF This includes information such as an index of autonomic nerve balance. These inferences can be made by applying known relationships based on primary information obtained using known measuring devices. LF/HF is a sympathetic nerve activity index calculated based on a heartbeat pattern or a pulse pattern.

Biological condition information is primary information obtained by measuring a subject using a measuring device, and includes information such as heartbeat, body temperature, amount of perspiration, and voice, for example.

(5-7) Modification G
In the above-described embodiment, the air conditioner 10 that performs temperature control and the lighting device 20 that performs illuminance control different from temperature control are described as examples of the environmental equipment that is a plurality of types of environment control means. .

However, the plurality of types of environment control means need not consist of a plurality of types of devices. If feasible, the temperature control may be treated as one type of environmental control means, the humidity control may be treated as another type of environmental control means, and the wind speed control may be treated as yet another type of environmental control means. .

In this case, for example, canceling control may be performed by changing the set temperature, the set humidity, and the set wind speed according to the type of external stimulus and the degree of change in the subject's arousal due to the external stimulus. good.

(5-8) Modification H
In the above embodiment, the air conditioner 10 for temperature control and the lighting device 20 for illuminance control have been described as examples of the environmental equipment that is the environment control means.

However, the environmental equipment, which is the environmental control means, is not limited to this.

For example, a humidity device capable of adjusting the humidity in the room where the subject is present may be used as the environmental equipment, which is the environment control means. Note that the humidity device may be integrally provided in an air conditioner that performs temperature control. According to the humidity device, for example, the indoor humidity can be detected by the humidity sensor, and the indoor humidity can be adjusted while observing the humidity, thereby changing the subject's wakefulness and the like. For example, when a subject's arousal level increases due to an unpleasant odor, by controlling the humidity device so that the humidity in the room decreases, the molecules of the odor component adhering to the wall materials and curtains in the room can be eliminated. By suppressing detachment and creating an environment in which molecules of odorous components can diffuse more easily, areas with high concentrations of odorous components can be eliminated in a short period of time. can be reduced. In addition, for example, in a room without lighting equipment or when the lighting equipment is turned off, if the illuminance in the room decreases due to cloudy weather and the subject's drowsiness increases, the indoor lighting By controlling the humidity device to reduce the humidity, the subject's drowsiness can be reduced.

Moreover, a wind speed device capable of adjusting the wind speed around the subject may be used as the environmental equipment, which is the environment control means. Note that the wind speed device may be integrally provided in an air conditioner that performs temperature control. For example, when a subject is stimulated by being distracted by the voice of a neighbor in an office, etc., by controlling the wind speed device to increase the wind speed around the subject, the voice can be reduced. The sound of the wind may be superimposed on the sound to create a situation in which it is difficult for the subject to hear what is being said. Here, the distinction between speech and other sounds is not particularly limited, and the external stimulus grasping section 61 may be able to grasp by using known speech recognition software. In addition, for example, in a room without a lighting device or when the lighting device is turned off, the illuminance in the room decreases due to cloudy weather, and if the subject's drowsiness increases, the subject may By controlling the wind speed device to increase the wind speed around the subject, the subject's sympathetic nerves may be dominant and drowsiness may be suppressed.

Further, as the environmental equipment, which is the environment control means, a lighting device capable of changing the color temperature of the room in which the subject is present may be used. According to the lighting device capable of adjusting the color temperature, it is possible to change the state of the object person, such as the level of arousal, by performing control to change the indoor color temperature. For example, in a room without an air conditioner or when the power of the air conditioner is turned off, if the target person feels hot due to the temperature rise in the room, a white color with a high color temperature will be used. Irradiate colored light to make the target person feel cool, and if the target person feels cold due to a drop in the room temperature, irradiate light with a low color temperature such as yellow, daylight color, or electric bulb color. You may make a target person feel warmth. The illumination device may be one capable of adjusting luminous flux, one capable of adjusting luminous intensity, or one capable of adjusting luminance. In addition, if the subject is stimulated to feel that the subject is too quiet to sleep because the volume or sound pressure is too low in the bedroom for a predetermined duration or longer, the lighting in the room is increased. By controlling the device, the subject's concentration on being too quiet may be diffused so that the subject's feeling of being too quiet may be less likely to be felt. In addition, if the subject is stimulated to feel that the subject is too quiet to sleep because the volume or sound pressure is too low in the bedroom for a predetermined duration or longer, the lighting will reduce the color temperature of the room. The device may be controlled to make the subject's parasympathetic nerves dominant, thereby causing drowsiness.

Further, as the environmental equipment, which is the environment control means, a ventilator capable of adjusting the concentration of carbon dioxide in the room by ventilating the room in which the subject is present may be used. According to the ventilation device, for example, while detecting the carbon dioxide concentration in the room with a carbon dioxide concentration sensor, by controlling the amount of ventilation while looking at the detected concentration, the carbon dioxide concentration in the room is adjusted, and the subject's You can change your arousal. For example, when the subject's arousal level increases due to an unpleasant odor, the subject's hyperarousal can be suppressed by performing ventilation using a ventilator so as to reduce the carbon dioxide concentration.

Further, as the environmental equipment, which is the environment control means, a deodorizing device capable of reducing the concentration of odorous components in the room where the subject is present may be used. According to the deodorizing device, for example, while detecting the concentration of odorous components in the room with an odor concentration sensor, the amount of deodorant or adsorbent to be sprayed is controlled while looking at the detected concentration, thereby eliminating the odor in the room. By adjusting the concentration of the component, the degree of arousal of the subject can be changed. For example, when the subject's arousal level rises due to the humidity grasped by a humidity sensor provided in an air conditioner or the like becoming higher than a predetermined value, if the environment has a high concentration of odorous components, deodorization By controlling the device to spray a deodorant or the like, it is possible to suppress hyperarousal of the subject.

In addition, as an environmental facility, which is an environment control means, a fragrance device such as an aroma diffuser capable of providing fragrance to a target person by spraying a predetermined aromatic component into the room where the target person is present is provided. may be used. Moreover, as the fragrance device, it is preferable to be able to spray multiple types of fragrance components according to the purpose of increasing or decreasing the arousal level of the subject. According to the fragrance device, the concentration of the aromatic component in the room is adjusted by, for example, detecting the concentration of the aromatic component in the room with an aromatic component concentration sensor and controlling the amount of the aromatic component to be sprayed while observing the concentration of the aromatic component. It is possible to change the state such as the degree of arousal of the subject. For example, when the temperature is higher than a predetermined value, the target person feels refreshed by spraying menthol or the like, which is an aromatic component provided in the fragrance device, so that the target person feels refreshed when the temperature is high. When the temperature is lower than a predetermined value, the temperature is lowered by spraying cinnamon, vanilla, etc., which are aromatic components provided in the aroma device, to make the subject feel warm. By doing so, the discomfort felt by the subject may be alleviated. To make a target person feel refreshed by spraying menthol or the like, which is a fragrant component provided in a fragrance device, when the humidity detected by a humidity sensor provided in an air conditioner or the like is higher than a predetermined value. Also, the discomfort felt by the subject due to the high humidity may be alleviated. Furthermore, when the sound sensor detects noise (high volume, high sound pressure, unpleasant frequency sound), by spraying lavender, etc., which is an aromatic component with a relaxing effect provided in the fragrance device, You may make it ease the object person's perception of noise.

Further, as the environmental equipment, which is the environment control means, an acoustic device capable of changing the sound environment in the room where the target person is present may be used. According to the acoustic device, for example, by selectively playing preset up-tempo music and slow-tempo music, it is possible to change the subject's arousal level. For example, when the room temperature rises and the subject's arousal level decreases, such as in a room without an air conditioner or when the power of the air conditioner is turned off, the stored By controlling the audio device to output and play up-tempo music data, it is possible to raise the subject's arousal. In addition, when the indoor humidity and temperature are higher than predetermined values and the subject's arousal level rises to hyperarousal, the acoustic device outputs and plays pre-stored tropical music data. By controlling , it is possible to match the high-temperature and high-humidity environment with the music, relax the subject, reduce the degree of alertness of the subject, and suppress hyperarousal. In addition, for example, when the target person is stimulated by the high temperature in the room, the audio device is controlled so as to perform output using pre-stored sound source data (wind chime sound) that makes the person feel cool. By doing so, the subject may be made to suppress the degree of feeling hot. Furthermore, when the subject is stimulated by being distracted by the voice of a neighbor in an office, etc., the acoustic device is controlled to output and play pre-stored environmental sound and air conditioning sound data. By doing so, it is possible to create a situation in which it is difficult for the target person to hear the content of the speech by superimposing the environmental sound on the sound of the speech.

Moreover, the environmental equipment, which is the environmental control means, may be a device for adjusting radiant heat that warms the subject himself/herself by radiant heat. An infrared heater etc. are mentioned as a device which adjusts radiant heat. This device for adjusting radiant heat directly warms the subject with the radiant heat, thereby obtaining an effect similar to that of canceling control by increasing the temperature of the air around the subject with an air conditioner.

(5-9) Modification I
In the above embodiment, in order to suppress an excessive increase in the arousal level of the subject by canceling control, it is determined in advance to increase the set temperature of the air conditioning device 10 or to decrease the set illuminance of the lighting device 20. was described as an example.

In response to this, for example, the tendency and degree of change in the arousal level of the subject according to the type of control content by the environmental facility are checked in advance, etc., and the environmental facility control device 100 is made to grasp it, and canceling control is executed. In some cases, only the control recognized by the environmental equipment control device 100 as the control capable of changing the subject's arousal level so as to suppress the influence of the external stimulus may be executed. For example, for a subject for whom control to reduce the set illuminance of the lighting device 20 has been found to be effective against noise as an external stimulus, the combination of the external stimulus and the control may be applied to the environmental equipment. It can be stored in advance in the external stimulus cancellation data section 75 of the control device 100 .

As a result, it becomes possible to use an accurate tendency of the subject's arousal level according to the type of control of the environmental equipment, and it is possible to more reliably suppress the influence of the external stimulus.

(5-10) Modification J
In the above embodiment, the case where the sound volume detected by the sound sensor 32 and having a predetermined value or more is regarded as an external stimulus has been described as an example.

On the other hand, when the frequency of the sound detected by the sound sensor 32 includes a predetermined unpleasant frequency, it may be regarded as an external stimulus. Furthermore, when the volume of a sound containing a predetermined unpleasant frequency is equal to or greater than a predetermined value, it may be treated as an external stimulus. Further, when the sound pressure (dB) detected by the sound sensor 32 exceeds a predetermined value, the external stimulus may be detected. Furthermore, when the volume or sound pressure (dB) of the sound detected by the sound sensor 32 is smaller than a predetermined value and continues for a predetermined duration or longer, the excessively quiet situation is grasped as a stimulus given to the subject, Controls may be made to counteract or moderate the stimulus.

(5-11) Modification K
In the above embodiment, in the cancellation control using the lighting device, control is performed to reduce the illuminance when the subject is stimulated by an odor, thereby suppressing excessive awakening of the subject. mentioned and explained.

On the other hand, the cancellation control using a lighting device that controls the illuminance is not limited to the cancellation control that cancels out the odor by decreasing the illuminance. It may be a control to disperse (disperse the sense of discomfort caused by the odor) and reduce the sensitivity of the subject to the odor, thereby canceling the odor. In addition, by controlling the lighting device to slightly increase the illuminance, the stimulus received by the subject when the lighting device is turned off and the room is dark and the abnormal noise is generated, so that the subject does not mind the abnormal sound. It may be a control to cancel out by suppressing the degree to which it becomes small.

(5-12) Modification L
In the above embodiment, in the cancellation control using an air conditioner that controls the temperature in the room, when the subject is receiving a stimulus related to sound, by performing control to increase the temperature in the room, the subject The control for suppressing the excessive awakening of is described as an example.

On the other hand, the canceling control using an air conditioner that controls the temperature is not limited to the canceling control of canceling the stimulus by the sound by increasing the temperature. Alternatively, canceling control may be performed in which the air conditioner is controlled so as to reduce the temperature in the room so that the subject is less likely to perceive the odor. In addition, when the subject is stimulated by a scent that induces sleepiness, such as lavender, the subject's sympathetic nerves are activated by controlling the air conditioner to lower the room temperature. It may be control. Furthermore, if the subject is stimulated during a lecture or conference because the tone of the speaker's speech induces drowsiness, the air conditioner is controlled to lower the temperature in the room. By doing so, the sympathetic nerves of the subject may be activated. Here, the method of detecting and determining whether or not the speaker's speech induces drowsiness is not particularly limited. If the change per unit time is within a predetermined value and continues for a predetermined duration or longer, it is determined that it induces drowsiness (for example, the external stimulus grasping unit 61 or the like determines). good too. Furthermore, if the subject is stimulated to feel that the subject is too quiet because the volume or sound pressure is too low in the office or bedroom for a predetermined duration or longer, the air pressure is adjusted to increase the room temperature. By controlling the harmonizing device, the parasympathetic nerves of the subject may be made dominant. In addition, for example, in a room without lighting equipment or when the lighting equipment is turned off, if the illuminance in the room decreases due to cloudy weather and the subject's drowsiness increases, the indoor lighting Cancellation control may be performed to suppress drowsiness of the subject by controlling the air conditioner so as to lower the temperature.

(5-13) Modification M
In the above embodiment and modified example, the case where the control details of the environmental equipment for canceling external stimuli such as sound and smell are determined in advance has been described as an example.

Here, even if the subject is receiving the same type of external stimulus, it is conceivable that the degree of influence of the external stimulus on the subject differs depending on the situation in which the subject is placed. For example, even if the subject is stimulated by the sound of speech, the situation is that the subject is trying to concentrate on some task, or the subject is trying to sleep. , the extent to which the stimulus of speech sounds has to be mitigated on the subject may differ. Therefore, even with the same stimulus, the degree of control of the environmental equipment may be varied according to the situation and purpose of the subject. The situation and purpose in which the subject is placed are not particularly limited, and examples thereof include a situation in which the subject is trying to concentrate, a situation in which he is trying to sleep, a situation in which he is trying to relax, and the like. The method for grasping the situation and purpose of the target person in the environmental facility control system 1 is not particularly limited. Alternatively, the data receiving unit 50 or the like of the environmental facility control device 100 may be configured to receive input from the subject. Further, in the external stimulus canceling data section 75 of the storage unit 70 of the environmental facility control device 100, canceling control corresponding to each situation and purpose of the subject is stored in advance. The control specifying unit 80 of 100 may specify the specific contents of the cancellation control based on the data in the external stimulus cancellation correspondence data unit 75 .

Instead of pre-storing the cancellation control corresponding to each situation and purpose of the subject in the external stimulus cancellation correspondence data section 75, the external stimulus cancellation correspondence data section 75 stores, for example, FIG. As shown in Table 5, effects that can be given to the subject for each of multiple types of cancellation control candidates using multiple types of environmental facilities provided in the environmental facility control system 1 (for each type of external stimulus received by the subject , the effect of each candidate for canceling control, which is for each situation or purpose in which the subject is placed, may be stored. In this case, the control specifying unit 80 of the environmental facility control device 100 determines the situation and purpose of the subject regarding the external stimulus that the subject is currently receiving, which is stored in the external stimulus cancellation corresponding data unit 75 . Of the effects stored for each, the most effective counteracting control for counteracting the external stimulus currently being received by the subject may be selected and specified. Furthermore, for each external stimulus received by the subject, the effect of each stimulus in the cancellation control in the situation where the subject is placed and for each purpose is specified for each individual subject. It is preferable to store in advance in the data section 75 .

For example, as shown in the table of FIG. 5, in a situation where subject A is trying to concentrate on work and speech (60 dB) is heard as an external stimulus, +10 for subject A Suppose that a person is in a state of excessive awakening (here, + indicates the degree of wakefulness, and - indicates the degree of drowsiness). In this situation, the effect obtained when the cancellation control (control candidate a) with the set temperature of -1 ° C. using the air conditioner is performed on the subject A (the arousal level of the subject A change is 0), and the effect (change in arousal level of subject A is -2), and the effect obtained when subject A is subjected to canceling control (control candidate c) with a set illuminance of -50 lx using a lighting device (change in arousal level of subject A is -1) and the effect obtained when the cancellation control (control candidate d) with the set illuminance of +50 lx using the lighting device is performed on the subject A (the change in the arousal level of the subject A is 0) , the effect obtained when canceling control (control candidate e) for playing predetermined environmental music using an audio device is performed on subject A (the change in the arousal level of subject A is -10); is stored in advance in the external stimulus cancellation correspondence data section 75 . Then, the control specifying unit 80 of the environmental facility control device 100 determines the external stimulus (speech of 60 dB) that the subject A is currently receiving, the situation in which the subject A is placed, and the purpose (concentration). By referring to the data in the external stimulus cancellation corresponding data section 75, the cancellation control (control candidate e) that plays predetermined environmental music using an audio device is performed to perform the cancellation control that can most effectively cancel the external stimulus. It can be identified that there is.

In this case, even if the stimulus is the same sound as the external stimulus, for example, as shown in the table of FIG. The stimulus received due to the continuation of may be treated as a separate stimulus. That is, a table showing a plurality of types of cancellation control candidates for each of these differentiated stimuli, for each subject, and for each situation and purpose in which the subject is placed is used as an external stimulus. It may be stored in the cancellation correspondence data section 75 . Specifically, in a situation where subject A is trying to concentrate on work and subject A is receiving an external stimulus due to a continuation of an environment that is too quiet (20 dB or less), subject A is in a state of excessive awakening at a degree of +5. In this situation, the effect obtained when the cancellation control (control candidate a) with the set temperature of -1 ° C. using the air conditioner is performed on the subject A (the arousal level of the subject A change is 0), and the effect (change in arousal level of subject A is -2), and the effect obtained when subject A is subjected to canceling control (control candidate c) with a set illuminance of -50 lx using a lighting device (change in arousal level of subject A is 0) and the effect obtained when the cancellation control (control candidate d) is performed on the subject A with the set illuminance set to +50 lx using the lighting device (the change in the arousal level of the subject A is -2) , the effect obtained when canceling control (control candidate e) for playing predetermined environmental music using an audio device is performed on subject A (the change in the arousal level of subject A is -5); is stored in advance in the external stimulus cancellation correspondence data section 75 . Then, the control specifying unit 80 of the environmental equipment control device 100 determines the external stimulus that the subject A is currently receiving (an external stimulus due to the continuation of an environment that is too quiet (20 dB or less)) and the subject A is placed. By referring to the data in the external stimulus cancellation corresponding data section 75, the cancellation control that can most effectively cancel the external stimulus for the situation and purpose (concentration) is performed in a predetermined environment using the acoustic device. It can be identified as cancellation control (control candidate e) for playing music.

In addition, the effect of the stimulus given to the subject by controlling the environmental equipment by performing the canceling control tends to weaken as the same stimulus is repeatedly received. Therefore, the control specifying unit 80 of the environmental facility control device 100, based on the frequency and degree of stimulus given to the subject using the same environmental facility, sets external stimulus cancellation data so as to reduce the above effect. It is preferable to select the cancellation control while correcting the data in the section 75 . For example, as shown in the table of FIG. 5, the effect obtained by canceling control during the initial period (0 to 10 minutes after the external stimulus) from the time of receiving the external stimulus, and the effect obtained from the time of receiving the external stimulus for a predetermined time (10 to 30 minutes after the external stimulus) may be stored in the external stimulus cancellation corresponding data section 75 separately from the effect obtained by the canceling control during the period after the elapse of (10 to 30 minutes after the external stimulus). As a result, not only can the most effective control be selected as the initial cancellation control after receiving the stimulus, but it is also possible to select the most effective control again as the cancellation control after some time has passed since the stimulus was received. be possible.
