Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is useful for emergency situations such as security guards on patrol, workers working in high places such as rooftops, or patients who require medical monitoring. Regarding the emergency situation detection device, which automatically detects the occurrence of an emergency situation and reports it to the supervisor, it is particularly important to detect the occurrence of an emergency situation by detecting the pulse of the person being monitored or the people around them. The present invention relates to an emergency situation detection device that can detect the occurrence of an emergency situation immediately or in advance.

[Conventional technology]

For example, in the event of an emergency situation, such as when a patrol guard encounters a trespasser such as a robber, struggles with an trespasser, is knocked unconscious by the struggle, or is arrested, etc. There is an urgent need to set up support and relief systems. In order to set up such a support system and rescue system for the guard man, it is necessary to notify the security center, that is, the side that sets up the support system and rescue system, that an emergency situation has occurred in the guard man and its surroundings.

Additionally, in the event of an emergency situation in which a worker works at a high location on a rooftop, such as injury due to a fall, prompt emergency work can prevent the unfortunate outcome of death from occurring.

Furthermore, for example, patients who have undergone organ transplant surgery should be monitored medically even after they return to their daily lives, and some patients who are released from intensive care may have the unfortunate outcome of worsening symptoms or death. There are many things that require relatively close monitoring to prevent them from occurring.

Conventionally, the occurrence of an emergency situation in and around a guard has been reported to a security center using a wireless communication device carried by the guard, a wireless communication installed in a paracall car, a telephone, or the like. In the event of an emergency situation such as death of a guard, the disruption of the regular communication required of the cartman or the reporting of the start and end of scheduled patrol work will be replaced by a notification of the occurrence of an emergency situation. .

In addition, for workers working at high places on rooftops, work supervisors are appointed to monitor the safety of the workers, and if a worker encounters an accident, the work supervisor will notify the emergency services. There is.

In addition, in the case of patients requiring medical monitoring, heart rate,
In some cases, an electrocardiogram device is used to detect blood pressure, etc., but such an electrocardiogram device is placed near the patient and is usually monitored by a nurse or accompanying family member. In some cases, a doctor is notified after being notified to a nurse center, etc.

[Problem to be solved by the invention]

In conventional security systems such as those described above, when an emergency situation occurs, it is not possible to report the occurrence of an emergency situation until the emergency situation has ended or the guard has escaped from the emergency situation. The problem is that the establishment of a support system or relief system for such an emergency situation is delayed, and the effectiveness of the support system or relief system is low.

In addition, work monitors are often not assigned to monitor the work of workers working in high places due to economic considerations and the urgency of the work.
In many cases, an emergency situation such as a fall is discovered only when the worker notices that the worker has not returned after a considerable amount of time has elapsed, exceeding the time required for the work, and goes to check on the worker. Moreover, delays in discovering such emergencies often lead to tragic consequences.

In the case of a patient who requires medical monitoring, an emergency situation may occur if no one is around, if the report is delayed, or if the nursing center that relays the report happens to be unmanned. Patients suffering from cancer may be left without receiving the necessary medical attention, and in some cases, the emergency situation may be detected too late, leading directly to unfortunate consequences.

The present invention has been made in consideration of the above-mentioned circumstances, and when an emergency situation occurs in or around the person to be monitored, the emergency situation is automatically detected by detecting changes in the pulse rate of the person being monitored. It is an object of the present invention to provide an emergency situation detection method and an emergency situation detection device that can detect the occurrence of a situation immediately or in advance and notify a supervisor.

[Means to solve the problem]

In order to achieve the above-mentioned "Objective 1," the emergency situation detection device according to the present invention includes a plurality of mobile stations and one fixed station, and each mobile station attaches the device to the monthly salary of the monitored person. a detection means for successively detecting physiological phenomena of the person to be monitored; and a detection means for sequentially detecting physiological phenomena of the person to be monitored; and determining whether an emergency situation has occurred by comparing a standard value of the physiological phenomenon of the person to be monitored and a detection value detected by the detection means. An emergency occurrence determination means, an emergency signal generation means for generating an emergency occurrence signal, and a transmission means for adding an identification signal for identifying the mobile station and an identification signal to the emergency occurrence signal and transmitting the same to the fixed station. , a circuit component holder that holds the mounting means, the detection means, the emergency occurrence determination means, the emergency signal generation means, and the transmission means; a bread 1- for wrapping the circuit component holder around the wrist; and a tensioning means for tensioning the hand so as to press against the artery from the outside of the skin,
The fixed station includes a reception means for receiving a signal transmitted from an arbitrary mobile station, an emergency occurrence station determination means for identifying the mobile station that transmitted the emergency occurrence signal based on the received signal (g), and an emergency occurrence station determination means for identifying the mobile station that transmitted the emergency occurrence signal based on The present invention is characterized by comprising a display means for displaying the occurrence of the emergency occurrence and the emergency occurrence station.

[Effect]

Physiological phenomena that show some kind of change when a person encounters an emergency situation include blood pressure, pulse rate or heart rate, adrenaline, internal secretions such as noratre and nolin, and external secretions such as seawater. However, among these, blood pressure and pulse rate are the most sensitive to the occurrence of an emergency situation, and changes in blood pressure and pulse rate can be detected immediately and quantitatively. Furthermore, when comparing blood pressure and pulse rate, pulse rate can be more easily measured non-invasively. Therefore, in the present invention, by monitoring the grid pulse rate of the person to be monitored and detecting changes in the pulse rate when an emergency situation occurs, or when detecting the risk of an emergency situation occurring, By detecting
The occurrence of an emergency situation for the person to be monitored or the surroundings is detected immediately or in advance.

By automatically displaying the emergency situation detected immediately or in advance on the display means of the fixed station, the supervisor is made aware of the occurrence of the emergency situation.

In the present invention, the mounting means may be configured such that the mobile station can be mounted on the monitored person so that the mobile station can detect the pulse of the monitored person, and the pulse detection position is also particularly limited. It's not a big deal, but my blood pressure is relatively high, and...
It is preferable to configure the device to detect the pulse of the radial artery, which can easily detect the pulse.

Therefore, in the present invention, the mounting means includes a circuit component holding section that holds the detection means, the emergency occurrence determination means, the emergency signal generation means, and the transmission means, the bread IS that wraps the circuit component holding section around the wrist, and the detection means. It is preferable to have a tensioning means for tensioning the band so as to press it against the radial artery from the outside of the skin.

The circuit component holding section may be integrated or may be divided into two or more parts. Furthermore, although the circuit component holding portion may be placed inside the hand or the tensioning device, at least a portion of it may be exposed outside the band, particularly on the side end surface of the hand, and the exposed surface may be artificially exposed to an emergency. It is preferable to provide a manually operated switch for generating a signal and a reset device that stops the operation of a mobile station that operates in the same way as when an emergency situation occurs even though no emergency situation actually occurs. Of course, the circuit component holding portion is not limited to a hard one, and may be semi-hard or soft.

Further, as the tensioning means, a buckle separate from the hunt may be provided that can extend and contract the interval between the two divided bunts.
+ It is also possible to use the pan l' as a tensioning means by constructing it with an elastic material such as a retractable hand or an elastic sheet.

Now, when a monitored person encounters an emergency situation, a change occurs in the monitored person's pulse. For example, if a go-first person discovers an illegal trespasser or is in a state of excitement due to a struggle, his or her heart rate will increase above the normal value, and if he is in a state of shock, such as when he is knocked down and faints, his heart rate will be at the normal value. decreases more than Furthermore, if there is bleeding during a fight or the like, the heart rate will further increase.

In the present invention, the detection means detects the pulse of the person to be monitored, in particular,
The occurrence of an emergency situation is detected by monitoring the pulse of the radial artery, through which blood flows with approximately the same high blood pressure as the brachial artery, and detecting changes in the pulse rate when the person being monitored encounters an emergency situation.

The detection means for detecting the pulse is not particularly limited, but it may be configured with a detection means having a blood vessel sound microphone that detects and emits blood vessel sounds of the radial artery and converts them into electrical signals. It is.

The element used in the vascular sound microphone that converts the sound waves into electrical signals is not particularly limited, but it can be made of piezoelectric ceramics that are small and have a wide range of detectable vibration frequency bands or audible ranges, or synthesized fine powder of piezoelectric ceramics. It is advantageous to use a piezoelectric element made of a composite piezoelectric material or the like dispersed in a resin.

According to the present invention, physiological phenomena such as the heart rate and blood pressure of the person to be monitored are detected using the detection means of the mobile station, and the detection value detected by the detection means and the normal value are compared in the emergency occurrence determination means. It is determined whether an emergency situation has occurred.

The normal value may be a value that is generally considered to be a normal value or an average value, for example, in the case of pulse rate, a value of 72 beats per minute. However, heart rate related to physiological phenomena,
Since blood pressure values vary from person to person, for example, the average value of multiple previous detection values, such as the previous detection value, the average value of the previous two detection values, the average value of the previous three detection values, etc. It is preferable to set it as a value.

Therefore, for example, a mobile station is provided with a shift register and normal value calculation means that have a capacity to sequentially and individually record the detection values of the previous plurality of times, and the detection values of the detection means are sequentially stored in the shift register. It is preferable that the average value of a plurality of previous detection values or the previous detection value obtained from the detection values by the normal value calculating means be used as the normal value. Furthermore, in the present invention, although it is possible to refer to a normal value as a single numerical value as described above, the above physiological phenomenon changes continuously within a certain range even under normal conditions. Therefore, it is more preferable to set the normal value to a value that has a certain spread.In other words, the detected value is compared with the above-mentioned general average value, the previous measurement value, the average value of the previous measurement values, etc. Rather than determining whether an emergency situation has occurred, it is determined whether the detected value deviates from or falls within a certain range, including the general average value, the previous measurement value, the average value of multiple previous measurement values, etc. For example, it is more preferable to determine whether an emergency situation has occurred based on whether the detected value is not included or included between the highest value and the lowest value of the previous multiple detected values. It is also more preferable.

When the emergency occurrence determination means determines that an emergency situation in which the monitored person requires rescue has occurred, the emergency occurrence signal generation means is activated, and the emergency occurrence signal and the identification received at the mobile station are transmitted via the transmission means. A signal is transmitted to a fixed station.

The configuration of the emergency signal and identification signal is not particularly limited, but since it is necessary to perform multiplex communication between multiple mobile stations and fixed stations, signal processing such as multiplexing and signal separation is required. It is advantageous to construct it with a simple digital signal.

The transmitting means may be configured to be capable of wirelessly transmitting a signal obtained by adding an identification signal to an emergency occurrence signal, for example, an identification signal generation circuit that generates an identification signal, and an identification signal generation circuit that adds an identification signal to an emergency occurrence signal. A signal addition circuit, a known RF modulation circuit, and a known transmission circuit are provided. In addition, the transmission means includes a synchronization signal generator that generates a synchronization signal for synchronizing signal processing at the fixed station, in order to be suitable for transmission to a fixed station that receives signals from multiple mobile stations simultaneously or sequentially. and a multiplexed signal forming circuit that adds the synchronization signal to the emergency occurrence signal and the identification signal at a predetermined timing.

Of course, the method for forming multiplexed signals at a mobile station is to multiplexly receive signals transmitted from each mobile station at a fixed station.
It is sufficient to use a method that corresponds to the method for separating the signals, and it is theoretically possible to adopt a method that uses different frequency bands of carrier waves, but as mentioned above, the synchronization signal and each mobile station's Multiplexing using a time-division method by differentiating the timing from the signal makes it possible to unify the band of the carrier wave transmitted and received between the mobile station and the fixed station, which simplifies the circuit configuration of the fixed station and the mobile station. It's advantageous.

The fixed station receives the emergency occurrence signal and identification signal transmitted from any mobile station using the receiving means, detects the emergency occurrence signal and identification signal No. 13 from the received signal, and determines which mobile station outputs the emergency occurrence signal. The emergency occurrence determination means determines whether the emergency occurs.

When the mobile station in which the emergency situation has occurred is determined by the emergency occurrence determination means, data regarding the occurrence of the emergency situation and the mobile station are displayed on the display means.

The method of displaying the occurrence of an emergency situation is not particularly limited, and may be displayed by, for example, lighting or blinking a lamp, displaying text, or the like.

Furthermore, the display method of a mobile station in which an emergency situation has occurred is not particularly limited; for example, the code of the mobile station, the name of the wearer, the planned course of movement, the current estimated position, etc. may be displayed in letters, figures, or on a map. One or more of various known display methods such as lighting or blinking of a plurality of lamps can be selected.

In this way, when an emergency situation occurs, the system automatically takes action at the same time as it occurs, or based on changes in the physiological phenomena of the person being monitored who senses the danger of an emergency situation occurring.
The occurrence of an emergency situation and the mobile station where the emergency situation has occurred are reported to a supervisor who monitors the display means of the fixed station.

Incidentally, even though the person being monitored has not actually encountered an emergency situation, physiological phenomena may change in the same way as when an emergency situation occurs. For example, if the person under surveillance thinks there is an illegal intruder due to an illusion, or if he or she suddenly moves his or her body, changes in physiological phenomena similar to those occurring when the person under observation encounters an emergency situation may occur. In such a case, if the display means of the fixed station erroneously indicates that an emergency situation has occurred, an unnecessary support system will be put in place, and the credibility of the displayed content will become doubtful.

Therefore, in the present invention, there are two cases in which changes in physiological phenomena similar to those observed in an emergency situation occur even though the person being monitored has not actually encountered an emergency situation, and cases in which the person being monitored in reality By configuring the display means to display the occurrence of an emergency situation and the mobile station where the emergency situation has occurred on the display means of the fixed station after confirming with the monitored person whether an emergency situation has occurred, The (?c+) sensitivity to the displayed content is increased, and unnecessary support systems are prevented.

That is, the fixed station is provided with a confirmation request signal transmitting means for outputting a confirmation request signal and an identification signal of the mobile station to the mobile station when the mobile station that has transmitted the emergency occurrence signal is identified;
Each mobile station includes a receiving means for receiving a confirmation request signal and a recognition signal from a fixed station, and a confirmation request signal for determining whether or not a confirmation request signal for the mobile station has been received based on the received confirmation request signal and recognition signal. a determination means, a notification means for notifying a confirmation request when the received confirmation request signal is for the mobile station, and a reset for manually stopping the operation of the notification means after receiving the confirmation request signal for the mobile station. and confirmation signal generating means for generating a confirmation signal and an identification signal when the reset means is not operated within a predetermined time after receiving the confirmation request signal,
Further, the fixed station is provided with confirmation signal determination means (fiN) for determining whether or not the fixed station has received a confirmation signal transmitted by the mobile station in response to the confirmation request signal. By configuring the system to display the occurrence of the event, the credibility of the display contents of the display means is increased, and it is possible to prevent unnecessary support systems from being set up.

The configurations and transmission/reception methods of the confirmation, request signals, and confirmation signals are not particularly limited, but in order to avoid complicating the circuit configuration, the same signal configuration and transmission/reception method as the configuration and transmission/reception method of the emergency signal and identification signal may be used. It is advantageous to use

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is an external side view of a mobile station of an emergency situation detection device according to an embodiment of the present invention, FIG. 2 is a circuit configuration diagram of the emergency situation detection device, and FIG. 3 is a diagram of the mobile station of the emergency situation detection device. FIG. 4 is a block diagram of the fixed station.

This emergency situation detection device is composed of a plurality of mobile stations 100 and one fixed station 200, and the mobile station 100 is used to detect a blood vessel table caused by vibration of the blood vessel wall of the radial artery of a person to be monitored, for example, a guard. It is attached to the guard's wrist.

That is, as shown in FIG. 1, the mobile station 100 includes a main case 101 as a part of the circuit component holding section, a hand 102,
It is equipped with a tension device 103 and a sub case 104 as the remaining part of the circuit component holding section, and is worn on the wrist of a guard person who is being monitored in the same way as a wristwatch.

Inside the main case 101, there is an emergency occurrence determination stage 120 shown in FIG.
50, confirmation request signal determining means 160, notification means 170,
In addition to the reset I/means 180 and the validation signal generation circuit 190, the identification signal shown in FIG. A central processing unit (hereinafter referred to as CPU) 1 for controlling the operation of each part of the memory ML mobile station 100 and a main circuit board P1 equipped with a battery (not shown) are housed. In addition, the main case 101
includes a manual operation switch 10 for manually operating the emergency signal generation means 130 by the person to be monitored;
5 is provided.

A detection means 110 shown in FIGS. 2 and 3 is housed in the sub case 104, and a blood vessel sound microphone 1 is installed inside the detection means 110.
No. 11 sound collecting portions 111a are exposed. This sound collecting section 111
a shows the main case 101, the hand 102, and the tension device 10.
3, the band 102 is tensioned by the tensioning device 103, so that it is pressed against the radial artery of the patient from outside the skin, and the vibration of the blood vessel wall of the radial artery is caused by piezoelectric ceramics or piezoelectric The signal is transmitted to a piezoelectric element made of a composite piezoelectric material in which fine ceramic powder is dispersed in a synthetic resin. The pressure with which the sound collector 111a is applied to the wrist only needs to be able to capture vibrations including low-frequency vibrations corresponding to the pulse of the blood vessel wall, so there is no need to apply pressure to the wrist when measuring blood pressure. It is sufficient that the strength is such that it hardly impedes the blood circulation immediately after the wear and does not cause any discomfort when worn, that is, it is strong enough to be pressed lightly with a finger.

In this embodiment, each circuit element of the mobile station 100 is divided into two cases 101 and 104 and housed, but all the circuit elements of the mobile station 100 may be housed in 10 cases. There is no hindrance to configuring it so that it is distributed and stored in three or more cases.

In the detecting means 110, first, the blood vessel sound of the radial artery is picked up by the blood vessel sound microphone 111 fixed to the hair 111, and is converted into an electrical signal.

The element used in the blood vessel sound microphone 111 that converts the six waves into electrical signals is made of piezoelectric ceramics that are small and whose vibration frequency range can be detected over a wide range including the audible range, or that are made of piezoelectric ceramics containing fine powder in a synthetic resin. Molecule B! A piezoelectric element made of a composite piezoelectric material or the like is used.

The blood vessel sound is detected by the blood vessel sound microphone 111 as a high frequency signal having undulations corresponding to the pulse, and the detection means 110 is configured to detect the pulse rate from this signal at every predetermined period.

That is, as shown in FIG.
After the blood vessel sound signal of the radial artery obtained through 1 is amplified by an amplifier 112, a high frequency component is removed by a low pass filter 113 to extract vibrations corresponding to pulse waves, and this low frequency vibration and a predetermined reference voltage are A pulse signal having the number of pulses corresponding to the pulse rate is formed by comparing the pulse forming circuit 115 with the reference voltage generated by the generating circuit 114 (1:).

Then, the sampling gate circuit 117 is made conductive for a predetermined period of time by the data 1~ signal output from the gate signal generation circuit 116, and the pulse counter 118 counts the number of pulses within the predetermined period of time, thereby obtaining the detected value. Pulse rate is detected.

Incidentally, the count number of the pulse counter 118 is read into the shift register 121 of the emergency occurrence determination means 120 at appropriate intervals, and at an appropriate time after this reading, the count number of the resetter 1 - υ source 4 - circuit 119 is read. It is designed to be reset from 1 to 1 by a reset signal. Further, the detection means 110 and the emergency occurrence determination means 120 are the tension device 103.
and are connected by a signal line (not shown) built into the band 102.

For example, the pulse rate will be higher than the normal value when the guard is excited, such as when he discovers an intruder or is fighting with the intruder, and will be lower than the normal value when the guard is in a state of shock, such as when he faints. Become.

Therefore, the emergency occurrence determining means 120 determines whether an emergency situation has occurred by determining whether the pulse rate is outside a predetermined range (normal value) that includes the normal pulse rate.

However, the normal value may be a value that is generally considered to be a normal value or an average value, for example, in the case of pulse rate, a value of 72 beats per minute. However, since there are large individual differences in the values of heart rate, blood pressure, etc. related to physiological phenomena, for example, the previous detected value, the average value of the previous two tests, the average value of the previous three detected values, etc. It is preferable to use the average value of the detected values several times before as the normal value.Also, since the above physiological phenomena change continuously within a certain range even under normal conditions, the above-mentioned It is more preferable to set the normal value to a value that has a certain range.In other words, it is more preferable to set the normal value to a value that has a certain range.In other words, the -i average value, the previous measurement value, or the average of multiple previous measurement values (a certain range including iQ, etc.) Alternatively, it is more preferable to determine whether an emergency situation has occurred by determining whether or not the detected value falls outside the range between the highest value and the lowest value among the detected values of the previous plurality of times.

Here, the emergency occurrence determination means 120 is provided with a shift 1 register 121 and an emergency occurrence determination circuit 122, and the shift register 121 is configured to sequentially store a total of four measured values, the current measurement and the previous three measurements. When a new measurement value is read, the old measurement value is replaced with the next measurement value, and the oldest measurement value is deleted. The non-lightning occurrence determination circuit 122 includes a shift register 12
Read the previous three measured values from 1, calculate the average value, and further calculate the limit value by adding a predetermined value to this average value and the lower limit value by subtracting the predetermined value from this average value. After that, the latest measured value is compared with its upper and lower limits, and it is determined whether an emergency situation has occurred by determining whether the latest measured value is outside or within the upper and lower limits. It is designed to judge.

When the manual operation switch 105 is operated by the person to be monitored or a person nearby, or when the emergency occurrence determination circuit 122 determines that an emergency situation has occurred, the emergency signal generation means 130 is activated to generate, for example, a predetermined number of bits. An emergency occurrence signal consisting of a digital signal is generated.

The emergency occurrence signal is input to the transmitting/receiving means 150, and passes through a confirmation signal priority circuit 151 that gives priority to the confirmation signal when a confirmation signal, which will be described later, is being output, to the identification signal successive output circuit 1.
There will be 4 people in 52. Next, the identification signal addition circuit 152 adds the identification signal read out from the memory M1 via the identification signal successive circuit 153, and the synchronization signal generated by the synchronization signal generation circuit 155 in the multiplexed signal formation circuit 154. is added to the emergency occurrence signal and the identification signal at a predetermined timing to form a multiplexed signal, and then RF modification/
It is modulated by the demodulation circuit 156 and transmitted from the transmission/reception circuit 157 to the fixed station 200.

As shown in FIG. 2, the fixed station 200 includes, in addition to an emergency occurrence station determining means 220 and a display means 230, a transmitting/receiving means 240 replacing the receiving means 210, and a confirmation request signal generating means 25.
0 and confirmation signal determining means 260 are provided. Furthermore, as shown in FIG. 4, the fixed station 200 records data regarding each mobile station 100, such as an identification signal, a wearer, a scheduled travel course, and a scheduled travel time. a display signal entry device 270 for inputting these data into the memory M2, and a central processing unit (hereinafter referred to as C
(referred to as PU) 2 and a recess/node device 280.

In the transmitting/receiving means 240, as shown in FIG. 4, a signal from an arbitrary mobile station 100 received by the transmitting/receiving circuit 241 is demodulated by the RF modulation/demodulation circuit 242, and then adjusted to a predetermined amplitude by the amplifier 243. amplified. Further, the transmitting/receiving means 240 is provided with a synchronizing signal separating means 244 for separating a synchronizing signal for timing control from the signal of the mobile station 100.

The emergency occurrence station determining means 220 separates the emergency occurrence signal from the output of the amplifier 243 using the emergency occurrence signal separation circuit 221, and the emergency occurrence signal formed by the emergency occurrence signal generation circuit 222 matches the separated emergency occurrence signal. Each time the emergency occurrence determination circuit 223 determines whether or not there is an emergency occurrence signal, the presence or absence of an emergency occurrence signal is determined, and when it is determined that there is an emergency signal, the emergency occurrence station determination circuit 224 determines which mobile station is the emergency occurrence station. do. In order to determine this emergency occurrence station,
The emergency occurrence station determination means 220 is provided with an identification signal successive circuit 225 that separates the identification signal from the output of the amplifier 243, stores the separated identification signal in a latch circuit 226, and launches when it is determined that there is an emergency signal. Input the identification signal latched in the circuit 226 to the emergency occurrence station determination circuit 224,
The flag signal writing circuit 227 writes a flag signal into the flag focus in the data of the mobile station 100 corresponding to this identification signal stored in the memory M2.

The confirmation request signal generation means 250 is the emergency occurrence station reading circuit 2
51 reads out the identification signal of the emergency station in which the flag signal has been written from the memory M2, and the confirmation request signal generation circuit 25
The confirmation request signal generated in step 2 and this identification signal are added by the confirmation request signal addition circuit 253, and the multiplexed signal forming circuit 245 of the transmitting/receiving means 240 synchronizes the confirmation request signal and the identification signal at a predetermined timing. A multiplexed signal is formed by adding the synchronization signals from the signal generation circuit 246, and after this multiplexed signal is modulated by the RF modulation/demodulation circuit 242, it is transmitted from the transmission/reception circuit 241 to the mobile station. There is.

The confirmation request signal and identification signal transmitted from the fixed station 200 are sent to the transmission/reception circuit 1 of each mobile station 100 as shown in FIG.
57, demodulated by an RF modulation/demodulation circuit 156, and then amplified to a predetermined amplitude by an amplifier 158. Further, from the output of the amplifier 158, a synchronization signal for controlling the operation timing of each part of the mobile station 100 is separated by a synchronization signal separation circuit 159 and inputted to the CPUI.

The confirmation request determination circuit then determines whether or not the confirmation request signal separated from the received signal by the confirmation request signal separation circuit 161 of the confirmation request signal determination circuit 160 matches the confirmation request signal generated by the confirmation request signal generation circuit 162. 163, it is determined whether or not a confirmation request has been made from the fixed station 200. When a confirmation request is made from the fixed station 200, the identification signal separated by the identification signal separation circuit 164 and latched in the launch circuit 165 and the identification signal read from the memory M1 via the identification signal succession circuit 166 are separated. Identification signal for determining whether the numbers match or not - defeat determination means 1
67, it is determined whether the confirmation request has been made to the mobile station 100.

When it is determined that the confirmation request signal has been sent to the mobile station 100, an emergency occurrence signal is transmitted from the mobile station 100 to the monitored person by activating the notification means 170, which is a buzzer, for example. In response to this, the fixed station 200 notifies that a confirmation request has been made, and the timer circuit 191 of the confirmation signal generation circuit 190 is set.

If an emergency situation requiring rescue has not actually occurred, the person to be monitored can reset the reset device 180 by
- By operating the switch 181 (shown in FIG. 5), the operation of the notification means 170 is stopped and the timer circuit 191 is reset. When an emergency situation that requires rescue actually occurs, the person to be monitored starts the timer circuit 191 after the notification means 170 starts.
For example, the reset device 180
By leaving the timer circuit 191 without operating it consciously or unconsciously, the timer circuit 191 activates the confirmation signal generation circuit 192, and the confirmation signal generation circuit 192 outputs a confirmation signal to the transmitting/receiving means 150.

In the transmitting/receiving means, the confirmation signal priority circuit 151 gives priority to the confirmation signal over the emergency occurrence signal, and the identification signal addition circuit 1
52, the identification signal addition circuit 152 adds a confirmation signal to the identification signal generated by the identification signal generation circuit 153, and the multiplexed signal forming circuit 154 adds a confirmation signal to the synchronization signal generated by the synchronization signal generation circuit 155. and the identification signal at a predetermined timing to form a multiplexed signal, which is modulated by the RF modulation/demodulation circuit 156 and transmitted from the transmission/reception circuit 157 to the fixed station 200.

At the fixed station 200, as shown in FIG.
'A multiplexed signal containing the confirmation signal and identification signal from the station 100 is received by the transmission/reception circuit 241, demodulated by the RF modulation/demodulation circuit 242, further amplified by the amplifier 243, and then confirmed by the confirmation signal determination means 260. The signal is confirmed and separated by the signal separation circuit 261.
