  The present invention relates to a monitoring device that monitors forgetting to turn off an electrical device, and a program that causes a computer to function as the monitoring device.

  Conventionally, there has been proposed a technique for determining that the user has forgotten to turn off when the use of the power source is detected in the setting of the outing mode (see, for example, Japanese Patent Application Publication No. 2010-49455 (hereinafter referred to as Document 1). )). In addition, in order to prevent unexpected power consumption when going out, a technique for detecting the presence or absence of abnormal use of power by comparing a reference power value registered by a user with a used power value has been proposed ( For example, see Japanese Patent Application Publication No. 2007-132804 (hereinafter referred to as Document 2)).

  Since the technique described in the above-mentioned document 1 determines that the user has forgotten to turn off when the use of the power source is detected in the state of being in the outing mode, actually, it is determined that the user has forgotten to turn off even when the user has not gone out. there is a possibility.

  On the other hand, the technique described in the above-mentioned document 2 compares the reference power value and the used power value when the check button is pressed. That is, in the technique described in the above-mentioned document 2, when the power usage value is expected to be equal to or lower than the reference power value, the check button is pressed, and at this time the power usage value exceeds the reference power value. It is determined as abnormal use (that is, there is unexpected power consumption).

  After all, in the techniques described in the above-mentioned documents 1 and 2, it is necessary for the user to instruct the timing for determining whether to forget to erase.

  An object of the present invention is to provide a monitoring device that does not require a user to instruct the timing for determining whether to forget to turn off an electrical device. Furthermore, an object of the present invention is to provide a program that causes a computer to function as the monitoring device.

  A monitoring device according to an aspect of the present invention includes a first acquisition unit configured to acquire information on a time change related to a power consumption value of a device to be monitored, and a person in a space where the device is used. A second acquisition unit configured to acquire information relating to the presence or absence of the device, and extracting a use state of the device and a use time of the device from information on a time change regarding the power consumption value, and a use state of the device and It is determined whether the device is in a candidate state to forget to turn off using the usage time of the device, the device is determined to be in the candidate state, and the second acquisition unit is absent A determination unit configured to output a determination result, and a presentation control configured to cause a predetermined presentation device to present output information based on the determination result of the determination unit With department And wherein the door.

  A program according to an embodiment of the present invention causes a computer to function as the monitoring device described above. Alternatively, the form is not limited to a program, and may be a recording medium that stores the program and can be read by a computer.

  According to the configuration according to the above aspect, when the second acquisition unit acquires information indicating the absence of a person, the determination unit outputs a determination result, so the timing for determining whether to forget to turn off the electrical device is used. There is an advantage that the user does not need to give instructions. In addition, according to the configuration according to the above aspect, the usage state of the device and the usage time of the device are extracted from the information on the time change of the power consumption value, and the device is forgotten to be turned off using the usage state of the device and the usage time of the device. Therefore, the determination accuracy is improved as compared with the case where the determination is made only by using the power supply.

It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment. It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment. It is a figure which shows the example of a display on the screen of a presentation apparatus in embodiment.

  The monitoring apparatus 10 described below has the configuration shown in FIG. The monitoring device 10 can be mounted on various devices. In the embodiment described below, as shown in FIG. 2, a plurality of devices 20 used in the house 30 (only one is shown in FIG. 2) are monitored, and the monitoring device 10 is installed in the house 30. A configuration example for communicating with a HEMS controller (HEMS: Home Energy Management System) 21 is assumed. That is, in the illustrated configuration example, the monitoring device 10 is realized by a computer server 101 that communicates with the HEMS controller 21 and a computer server 102 that communicates with the terminal device 22.

  The house 30 is not limited to a detached house but may be a collective house. In addition, the device 20 is not limited to use in the house 30, and the technique of the present embodiment can be employed when used in an office building, a store building, or the like.

  The monitoring device 10 includes a computer as a main hardware element, and is configured by executing a program that causes the computer to function as the monitoring device 10 described below. The program is preferably provided using a computer-readable recording medium. The HEMS controller 21 also includes a processor that operates by executing a program.

  Hereinafter, the HEMS controller 21 is simply referred to as a controller, and the computer servers 101 and 102 are referred to as servers. The terminal device 22 may be a communication device such as a smartphone, a tablet terminal, and a personal computer, and may have a function of presenting information and a function of instructing the servers 101 and 102.

  The controller 21 has a function of acquiring the power consumption value measured by the measuring device 31 and transmitting the acquired power consumption value to the server 101. The measuring device 31 measures the power passing through each branch circuit branched by the distribution board 32 installed in the house 30. The device 20 used in the house 30 is supplied with power from a branch circuit branched by the distribution board 32.

  The measuring device 31 includes a current sensor selected from a clamp-type current transformer, a Rogowski coil, and the like, and uses a current value detected by the current sensor and a voltage value between lines in the branch circuit for each branch circuit. Is calculated. As the power value to be calculated, an average value of the power amount per unit time is actually used. The unit time is selected in the range of 1 second to 10 minutes, and preferably 30 seconds or 1 minute is selected.

  In the illustrated example, the controller 21 and the server 101 communicate through an electric communication line NT1 such as the Internet. When the telecommunications line NT1 is the Internet, a technology such as VPN (Virtual Private Network) is employed to protect the communication contents, and the controller 21 is connected to the telecommunications line NT1 through a router 23 having a firewall. There is a need. On the other hand, the terminal device 22 communicates with the server 102 through a telecommunication line NT2 such as a mobile communication network or the Internet. The telecommunication line NT2 may also be used as the telecommunication line NT1.

  It is desirable that the server 101 and the server 102 communicate through a communication path different from the telecommunication lines NT1 and NT2. Further, the server 101 and the server 102 may be configured to share the same hardware. The server 102 mainly has a function of generating output information of the monitoring device 10 and presenting it to the terminal device 22. On the other hand, the server 101 has a function of detecting forgetting to erase by mainly using information acquired from the controller 21.

  Here, since the server 101 analyzes the time change of the information acquired from the controller 21, a server 103 that temporarily stores information transmitted from the controller 21 is provided between the controller 21 and the server 101. May be. Moreover, the controller 21 of this embodiment acquires information from the human sensor 24 that monitors the presence or absence of a person for each room in the house 30.

  The human sensor 24 is configured to detect infrared rays emitted from a human body using a pyroelectric infrared sensor. However, if it is necessary to detect the presence / absence of a person with higher accuracy than the pyroelectric infrared sensor, the human sensor 24 may be configured to detect the presence / absence of a person by computer image processing of an image captured by a television camera. Good.

  As shown in FIG. 1, the monitoring apparatus 10 configured by the servers 101 and 102 relates to the first acquisition unit 11 that acquires information on the power consumption value from the controller 21 and the presence or absence of a person detected by the human sensor 24. And a second acquisition unit 12 that acquires information. The first acquisition unit 11 does not target all the devices 20 under the control of the controller 21 but acquires information related to the power consumption value for the devices 20 selected as the monitoring targets.

  The device 20 selected as the monitoring target may be a device 20 that is usually operated by a person. For example, a device 20 such as an air conditioner, an IH cooking heater, a lighting fixture, and a heating device (an electric floor heating device, an electric stove, an electric heater, an electric kotatsu, an electric blanket, etc.) can be selected as a monitoring target. On the other hand, devices 20 that are not normally operated by humans, such as refrigerators and hot water storage hot water heaters, are preferably excluded from monitoring targets.

  As described above, since the power consumption value of the device 20 is obtained every unit time, the first acquisition unit 11 displays the power information in which the power consumption value is associated with the date and time when the power consumption value is measured. Get from. That is, the 1st acquisition part 11 acquires the information of the time change regarding the power consumption value of the apparatus 20 which is a monitoring object. In addition, the second acquisition unit 12 obtains information on the presence / absence of a person in a space where the device 20 selected as a monitoring target is used (that is, a space in which the device 20 is disposed when power is consumed). Obtained from the controller 21.

  The monitoring device 10 outputs a determination result regarding forgetting to erase using the information on the time change regarding the power consumption value acquired by the first acquisition unit 11 and the information on the presence / absence of the person acquired by the second acquisition unit 12. The determination part 13 to be provided is provided. The determination unit 13 determines whether the device 20 is in a candidate state forgotten to be turned off based on the use state of the device 20 and the use time of the device 20. The determination unit 13 outputs a determination result when the information acquired by the second acquisition unit 12 indicates the absence of a person during the period in which the device 20 is determined to be in the candidate state.

  The usage state of the device 20 and the usage time of the device 20 are extracted from information on a time change regarding the power consumption value of the device 20. The power consumption value increases during the period in which the device 20 is operating as compared to the period in which the device 20 is inactive. Using this, the determination unit 13 sets an appropriate threshold value for the power consumption value, regards the state where the power consumption value exceeds the threshold value as the state where the device 20 is operating, and the device 20 is operating. The time during which the state continues is regarded as the usage time of the device 20. Hereinafter, the threshold set for the power consumption value is referred to as a power determination value.

  The power determination value as a threshold for the power consumption value is a value that is smaller than the minimum value of the power consumption value during the period in which the device 20 is operating and greater than 0 for the device 20 that does not consume power during the non-operation period. Determined. Further, for a device 20 that consumes power as standby power even in a non-operating period, the value is smaller than the minimum power consumption value during the period in which the device 20 is operating and larger than the standby power value. A power determination value is determined.

  If the power determination value is appropriately set, the determination unit 13 can determine whether the device 20 is operating or non-operating based on the time change of the power consumption value. . Further, the determination unit 13 can extract the date and time when the operation of the device 20 starts and the usage time until the operation of the device 20 stops based on the time change of the power consumption value. As described above, the measured date corresponds to the power consumption value.

  Therefore, the determination unit 13 obtains the date and time when the power consumption value exceeds the power determination value as the date and time when the device 20 started to operate, and then the device 20 operates the date and time when the power consumption value became equal to or less than the power determination value. Calculate as the date and time of stoppage. The determination unit 13 obtains the time from the date and time when the device 20 starts operating to the date and time when the device 20 stops operating as the usage time of the device 20.

  By the way, the state of forgetting to turn off the device 20 is a state in which the device 20 is operating and the user does not notice that it is operating. On the other hand, if the user knows that the device 20 is operating, even if the device 20 has been used continuously for a long time, it cannot necessarily be said that the device 20 has been forgotten to be turned off. The determination unit 13 according to the present embodiment determines that the device 20 is forgotten to be turned off on the condition that the device 20 is continuously operated when no person is present in the space where the device 20 is used.

  Therefore, the determination unit 13 determines whether or not the device 20 is in a candidate state forgetting to turn off using the use state and use time of the device 20 extracted from the information on the time change of the power consumption value. The candidate state is a state that is a candidate for forgetting to erase the device 20, and normally, if the period during which the device 20 is determined to be operating continues for a long time, the candidate state is forgotten to be erased. Become. Here, the determination unit 13 not only determines that the device 20 is operating when the power consumption value exceeds the power determination value, but also determines that the power consumption value exceeds the power determination value. It is determined that the device 20 is in the candidate state when the duration time of the current state exceeds the predetermined period determination value. The power determination value and the period determination value used for determining the candidate state are set according to the device 20.

  As described above, the determination unit 13 determines that the device 20 is in the candidate state when the duration of the state in which the power consumption value exceeds the power determination value is in a state in which the predetermined period determination value is exceeded. It is desirable to be configured to do so. According to this configuration, if the power determination value and the period determination value are appropriately set with respect to the information regarding the time change of the power consumption value, the determination unit 13 can easily determine the candidate state. .

  Note that depending on the type of the device 20, the power consumption value may fluctuate greatly in a state where the device 20 is continuously used. For example, the power consumption value of the device 20 such as an iron or an oven toaster increases rapidly until a predetermined temperature is reached, and then the power consumption value repeatedly increases and decreases. In such a device 20, there are cases where the power consumption value exceeds the power determination value and the power consumption value is equal to or less than the power determination value during the period in which the device 20 is operating. Therefore, the determination unit 13 must determine that this type of device 20 is continuously used during a period in which the power consumption value repeatedly increases and decreases. For example, the determination unit 13 suspends the determination when the power consumption value exceeds the power determination value from the state where the power consumption value exceeds the power determination value, and the power consumption value is determined as the power determination after a predetermined determination time has elapsed. If it does not exceed the value, it may be determined that the operation of the device 20 has stopped.

  The power determination value and the period determination value are set for each device 20 and stored in the storage unit 131 provided in the determination unit 13. The power determination value and the period determination value may be set in advance for each type of device 20 in the manufacturing stage of the monitoring device 10. However, in order to set the power determination value and the period determination value more appropriately, it is desirable that the administrator of the monitoring device 10 sets the details after analyzing the past power consumption value history for the corresponding device 20. . The power determination value and the period determination value are determined according to each device 20. In addition, depending on the device 20, the power determination value and the period determination value may vary depending on the season, and may vary depending on whether it is a weekday or a holiday.

  The determination unit 13 is based on the device determination unit 132 that performs processing for extracting the device 20 in the candidate state based on the information on the temporal change in the power consumption value, and information on the presence / absence of the person acquired by the second acquisition unit 12. A person determination unit 133 that divides the period in which the person exists and the period in which the person is absent. The storage unit 131, the device determination unit 132, and the person determination unit 133 have a configuration in which the determination unit 13 is divided into functional modules, and these modules need to correspond one-to-one with hardware elements. Absent.

  The first acquisition unit 11, the second acquisition unit 12, and the determination unit 13 are configured by the server 101, and the determination result output by the determination unit 13 is delivered to the server 102. The server 102 constitutes the presentation control unit 14 that generates output information using the determination result of the determination unit 13 and presents the output information to the terminal device 22 as a presentation device. The output information generated by the presentation control unit 14 is notified to the terminal device 22 registered in advance as a notification destination by a push method.

  The output information generated by the presentation control unit 14 in response to the determination result of the determination unit 13 configures the screens illustrated in FIGS. 3 to 5, for example. The illustrated example assumes a configuration in which the terminal device 22 is a smartphone or a tablet terminal and includes an operation display device in which a transparent touch panel is superimposed on a display screen.

  The output information on the screen shown in FIG. 3 includes information for specifying the corresponding device 20 and information for specifying a space in which the corresponding device 20 is used. Also, the output information on the screen shown in FIG. 4 includes information for identifying the corresponding device 20, information for identifying a space in which the corresponding device 20 is used, and a time at which use of the corresponding device 20 is started. , And the time during which the corresponding device 20 is being used. Further, the output information on the screen shown in FIG. 4 includes information on the contact address and information on the contact method.

  The fields displayed on the screen shown in FIG. 3 are a content field F11 for displaying the notification content, a button field B11 for returning the confirmation of the notification content to the server 102, and the notification content in more detail. And a button field B12 that is operated for confirmation. The screen shown in FIG. 4 is an example of a screen that is displayed after the button field B12 in FIG. 3 is touched, and information about time is added as notification contents. The fields displayed on the screen include a content field F21 for displaying the notification content, and button fields B21 and B22 in which a contact address and a contact method in the case of contacting in response to the notification content are associated with each other.

  A button field B23 for presenting a usage amount graph is also added to this screen. When the button field B23 is touch-operated, as shown in FIG. 5, a field F31 that indicates the amount of power consumed by the corresponding device 20 every predetermined time (for example, one hour) in a predetermined period of about one day is displayed in a bar graph. Displayed on the screen. The screen shown in FIG. 5 shows a change with time since the power consumption value of the device 20 has risen, so that the user can determine whether or not the user has forgotten to turn off the device 20.

  As described above, the monitoring device 10 according to the present embodiment includes the first acquisition unit 11, the second acquisition unit 12, the determination unit 13, and the presentation control unit 14. The 1st acquisition part 11 is comprised so that the information of the time change regarding the power consumption value of the apparatus 20 which is a monitoring object may be acquired. The second acquisition unit 12 is configured to acquire information related to the presence or absence of a person in the space where the device 20 is used. The determination unit 13 extracts the usage state of the device 20 and the usage time of the device 20 from the information on the time change regarding the power consumption value, and the device 20 is a candidate for the device 20 to forget to turn off using the usage state of the device 20 and the usage time of the device 20. It is configured to determine whether it is in a state. The determination unit 13 is configured to output a determination result when it is determined that the device 20 is in a candidate state and the second acquisition unit 12 has acquired information indicating the absence of a person. Is done. The presentation control unit 14 is configured to cause a predetermined presentation device (terminal device 22) to present output information based on the determination result of the determination unit 13.

  According to this configuration, the determination unit 13 extracts the usage state and usage time of the device 20 from the time change information regarding the power consumption value of the device 20, and the device 20 is turned off using the usage state and usage time of the device 20. It is determined whether or not the candidate state is forgotten. Furthermore, the determination unit 13 outputs a determination result when it is determined that the device 20 is in a candidate state and information indicating the absence of a person is acquired. Therefore, when there is no user in the space where the device 20 is used and there is a possibility that the user may not be aware that the device 20 is operating, the output information is presented and used. It becomes possible to make the person aware.

  In the monitoring device 10, the determination unit 13 determines that the device 20 is in the candidate state when the duration of the state where the power consumption value exceeds the power determination value is in a state where it exceeds the predetermined period determination value. It is preferable to be configured to do so.

  In the monitoring device 10, it is preferable that the output information includes information for specifying the device 20 and information for specifying a space in which the device 20 is used.

May be.

  In the configuration example described above, the measurement device 31 measures the power consumption value for each branch circuit branched by the distribution board 32. Therefore, if the devices 20 are not connected to the branch circuit on a one-to-one basis, the power consumption value acquired by the first acquisition unit 11 may be a combination of the power consumption values of the plurality of devices 20. In other words, the power consumption value related to the monitoring target device 20 cannot be separated from the power consumption value acquired by the first acquisition unit 11.

  Therefore, the monitoring device 10 may be configured to extract the power consumption value for each device 20 from the power consumption value of the branch circuit by extracting the feature amount of the device 20 from the time change of the power consumption value. Further, since the controller 21 can communicate with the device 20, the power consumption value for each device 20 can be extracted by combining the identification information of the device 20 known by the controller 21 with the power consumption value. .

  When the receptacle to which the device 20 is connected is configured to measure the power consumption value, the controller 21 may acquire the power consumption value from the receptacle. Further, if the device 20 is provided with a function for measuring the power consumption of the device 20, the controller 21 may acquire the power consumption value from the device 20.
