Abstract

PURPOSE:To attain automatically urgent communication for danger of life by mounting a living body signal detector to a human body and starting the automatic communication system by using the signal of said detector. CONSTITUTION:In Figure, 1-1-1-n are n-sets of a vital signal detecting sensor, which are mounted directly onto the human body. As a vital signal, the pulse tension of a heart blood vessel, a blood stream rate, heart sounds, and the number of breathing are used. The vital signal detected by the sensors is applied to a ratio transmission circuit 5 via a multiplexer 2 and a switch 3. When the switch 3 is operated by the decision, the decision signal generated from the circuit 4 is connected to the circuit 5 to interrupt the vital signal. The vital signal or the decision signal transmitted from the circuit 5 is received and applied to a circuit 11 or 12 via a discrimination section 7. The circuits 11, 12 discriminate the content of the signal by the signal from the decision section 7 and the output of the installation type surrounding condition detecting sensors 8-1-8-n, and installation type decision signal generating circuits 9, 10 and apply the content to the circuit 13 to select a preset informing address.

Description

[Detailed description of the invention] a1 Technical field of invention It is related to the method.

b Technology background Living things, especially humans, suffer from sudden illnesses, fires, robberies, and natural disasters.

When a person's life is in danger due to an accident, etc., a call to the fire department, police, hospital, etc. is made to seek help. #'i The victim or a third party used the eL story. However, when making p-reports using 14L Kinuta, especially in cases of fires, accidents, etc. that require promptness, there are cases where incorrect dialing,
There was a drawback that the dial connection part took time. Furthermore, in cases such as robbery, it is impossible to report the intruder in front of him. The promptness and confidentiality of these are Jose M.

, BME-29,A 5. May1982)
In this method, when the victim senses danger, he or she carries a small transmitter and transmits radio waves.The transmitted radio waves are received by a receiver in the range of 20 to 100 fi, and are automatically activated. Activates the dialer and sends encoded signals. In addition, automatic dialers have multiple destinations stored in the OC8. Problems with conventional technology By the way, even with this method, if the person loses consciousness for some reason, the small transmitter They are unable to transmit radio waves and cannot call for help, which can lead to death. Furthermore, recently, the number of people living alone, especially the elderly population, has increased, and in many cases, death is only confirmed several days to several months after death. however,
Most of them would have survived if they had been rescued within an hour of losing consciousness.

60 Purpose of the Invention Therefore, in the present invention, all biosignal detectors are attached to the human body, and the output signals are used to determine and detect danger to life, and by activating an automatic communication system, it is possible to detect the situation after loss of consciousness. However, the O00 invention aims to provide a method for automatically communicating emergency messages in case of danger to life.The present invention detects biological signals from the body of a living organism, and detects the emergency of the living organism determined based on changes in the biological signals. In a method of reporting a situation to a third party, a biosignal detection unit that is attached to the body of a living creature and detects the biosignal of the creature, and a biosignal detection unit that determines whether the biosignal detected by the biosignal detection unit is abnormal. At least a signal abnormality determination section, a transmission control section activated by an abnormality determination signal from the biological signal abnormality determination section, a transmission signal generation section, and a reception section that receives the signal transmitted from the transmission signal generation section. A system using wireless communication for at least part of the connection of the biological signal detection section, the biological signal abnormality determination section, the transmission control section, the transmission signal generation section, and the reception section as a component, as necessary;
It is preferable that the receiving section is an automatic telephone connection section activated by a signal transmitted by the transmission signal generating section.

10 Embodiments of the Invention FIG. 1 is a block diagram showing the overall system of an emergency communication system that is an embodiment of the present invention, in which 1-1 to 1-n are biological signal detection sensors, 2 is a multiplexer, and 3 is a changeover switch, 4 is an intention signal generation circuit, 5 is a wireless transmission circuit, 6
is a wireless receiving circuit, 7 is a biological signal abnormality determination unit, 8-1.8
-2. ...8-n is an installation type surrounding condition detection sensor, 9.10 is an installer's intention signal generation circuit, 11.12 is a malfunction elimination circuit, 13 is a transmission control and transmission signal generation circuit, and 14 is a 15 is an automatic telephone connection unit, and 7 to 16 are installation units for connecting to a telephone system.

1-1 to 1-n are n biological signal detection sensors that are directly attached to the human body. Biometric No. 46 includes pulse pressure in the cardiovascular system, blood flow measured by electromagnetic flow in the arm, etc., heart sounds, blood flow sounds, ultrasound Doppler sounds, and electrocardiography.

In general, voltages such as myoelectricity, electroencephalogram, etc., electric impedance of the living body (direct current, or current), respiration frequency, pH of the skin, color of the body surface, reflectance of a specific color wavelength band, and density can be used. Slightly invasive sensors may be used for people with certain medical conditions. For example, diabetics may want to add a blood sugar sensor. The biological signals detected by the n sensors 1-1 to 1-n are measured by a multiplexer 2 at an appropriate frequency according to the rate of change of each detection t, and are multiplexed by carrier frequency. ification.

Multiplexing through digitalization through A/DK conversion, etc.
Transmission is made possible through as few communication paths as possible. Switch 3 typically connects the biosignal to circuit 5. Further, when the switch 3 is operated voluntarily, the volitional signal generated from the circuit 4 is connected to the circuit 5, and the biological signal is disconnected.
5 is the part of this system that is attached to the living body.0 This part that is attached to the living body needs to be operated by batteries, and it is important to minimize power consumption, be small and lightweight, and be able to freely move the living body. In addition, the biological signals to be transmitted, or will be transmitted by the circuit 5, which operates intermittently to measure and/or transmit in order to reduce power consumption, are used for action-free communication. The biosignal or the will signal received by the circuit 6 is determined by the determining unit 7 as to whether it is a biosignal or a will signal.The biosignal is then compared with a normal value. , detects abnormal values and determines the danger to life based on their correlations. For normal values, use the average over a certain period, etc., and add a learning function to allow more sensitive abnormality detection. s- i, s-2,...
, 8-n is an installed ambient condition detection sensor that detects city gas, CO gas, smoke, temperature rise, etc., and determines the danger to life. 9.10 is an installation-type will signal generation circuit, which is effective when facing an intruder or robber who is extremely urgent and whose freedom of movement is restricted, whereas circuit 4, which is installed on a living body, is effective when facing an intruder or robber who restricts freedom of movement. It can be divided into types such as 9 is for fire, 10 is for thief, 2 is for injury, 2 is for intruder, etc., and it is possible to select the most appropriate contact point. The circuit 11 includes a determination unit 7. and sensor 8-1.8-2.
・・When an abnormal signal occurs in the biological signal and the surrounding signal sent from 8-n due to a sensor failure, noise contamination, etc., the time when the abnormal signal occurs, for example, 10 to 60 seconds, etc. It is determined whether the set time is continuous or not, and the consistency of the sensor is determined as a double or triple system. Malfunction f: Eliminate. In addition, an acoustic alarm is issued when the first abnormality is detected, and when the living body is conscious, the living body itself determines the truth or falsehood, and in the case of malfunction, the transmission to subsequent stages is artificially cut off. A certain holding time may be provided. Similarly, the circuit 12 is designed to exclude cases where the pushbutton is not activated by a volitional signal, such as when another object collides with the pushbutton or by someone else's voice. For example, W1 activates two or more operations separated by more than 1 second.Furthermore, for example, an acoustic or optical alarm is issued at the first activation, and then a preset hold time (for example, 20 seconds) is activated. )
After the alarm continues, a signal is sent to the next stage, and if it is an error, the connection to the next stage can be interrupted by manually canceling it or by operating a button, etc. You can make yourself smile by making it possible. circuit 11
．． A biosignal, a Reishi signal, sent to the circuit 13 via 12.

Depending on the surrounding signal, the circuit 13 selects a preset reporting destination. For example, in the case of a biological signal, a selection sound is made to select a contact point such as a fire department to call an ambulance, and in the case of a will signal, a police station, etc. is selected. Then, the circuit 15 executes a series of connection procedures to the telephone system 16 according to the telephone number stored in the circuit 15 in advance according to instructions from the circuit 13. When the telephone is connected, the circuit 13 directs the memory 14 to read out the message corresponding to the contact. The message is then converted into voice by the circuit 13 and transmitted to the telephone system 16. 7゜11.
12, 13, and 14 can all be executed on a single microcomputer. As these power sources, although not shown as an example, it is desirable to use a rechargeable battery that is constantly charged by a commercial power source. Also, a clock system for overall control, and others are omitted from the examples. . The clocks of the wearable and portable parts may be independent, and communication may be started from the wearable and portable part, or may be started in advance from the installation part. Therefore, the communication between the circuit 5 and the circuit 6 may be one-sided communication from the circuit 5 to the circuit 6, or may be two-way communication.

The automatic communication system described above requires at least a biological signal detection sensor to be attached directly to the living body. Therefore, at least an independent biological signal detection sensor may be attached to the living body, such as a wristwatch, necklace, arm ring, or finger ring.

When worn on the human body by integrally attaching it to a belt, glasses, earphones, underwear, etc., the discomfort can be reduced.

FIG. 2 shows a wristwatch with a biological signal detection sensor and a volitional signal generation circuit attached, 51 is a band part, 52 is a wearing/carrying part, 53 is a pressure sensor, 54 is a microphone, and 55 is a wristwatch. indicate pushbuttons. Moreover, this wristwatch includes items 1 to 5 in FIG.

The wearing/carrying part 52 attached to the band 51 is made of a whole piece and conducts body temperature well, making it possible to measure the body temperature with an internal thermistor, thermocouple, etc. The pressure sensor 53 has a flexible coating and low tensile strain N1, a semiconductor strain meter,
Alternatively, it can be made of an organic piezoelectric film such as PVD. The microphone 54 responds to even higher frequencies and detects blood flow sounds. When the push button 55 is operated, an intention signal is transmitted to the intention signal generation circuit.

It is desirable that the mounting φ carrying portion 52 and other surfaces be covered with a heat insulating material so that they are not affected by the ambient temperature.

In order to prevent the push button 55 from being pressed due to inadvertent contact with a foreign object, in this embodiment, as shown in the figure, the intention signal is often generated by operating the switch, but the intention signal is generated by voice. It may also be configured to occur. Further, in this embodiment, a telephone system is used for reporting, but a public communication network, a private extension of a large building, etc. may also be used. Further, in this embodiment, the surrounding condition sensor is installed, but it may be installed directly on the living body.

g0 Effects of the Invention According to the present invention, even if a living body wearing a biosignal detection unit initially loses consciousness for some reason, the danger to the living body can be reported to a third party due to a change in the biosignal. can do. In addition to quickly and confidentially reporting the will signal to a third party, it is also possible to report danger even in a restrained situation.

In addition, the surrounding condition sensor can also notify you of impending danger, such as when you are sleeping or sleeping. Furthermore, if the surrounding condition sensor is installed, it can also notify you of danger approaching your house when you are out and about.

Additionally, the present invention can be easily connected to social emergency systems (police, fire department, etc.).
