Abstract

PROBLEM TO BE SOLVED: To automatically send a rescue signal when a shock is applied to the rescue signal sending device and eliminates the need for artificial operation by placing a signal sending means in operation by a control means when a shock detecting means detects the shock. SOLUTION: A shock sensor 21 is a sensor which detects the shock applied to the rescue signal sending device and detects a constant shock when it is applied. Therefore, when a shock larger than a certain value is applied to a human body, it is detected by the shock sensor and specially in case of various disaster such as house collapse, a large shock is applied to the human body, so a rescue signal is automatically sent according to the output of the shock sensor 21. A control means 30 inputs signals from a manual switch 8 and the shock sensor 21, determines whether or not respective sending circuits 5a-7a can be actuated and sent signal data contents at the time of the actuation of oscillation circuits 5a-7a according to those signal inputs, and outputs command signals corresponding to the result to the respective oscillation circuits 5a-7a and a liquid crystal display part 2.

[0020]

An embodiment of the present invention will be described with reference to the drawings. In this embodiment, the case where the rescue signal transmission device is applied to a wristwatch will be described. However, in addition to a wristwatch, it is miniaturized and incorporated into something normally worn such as clothes buttons, necklaces, pendants and other decorative items. Is desirable.

In FIG. 1, reference numeral 1 denotes a wrist watch incorporating a rescue signal transmitting device, in which a liquid crystal display section 2 is arranged at the center of the upper part of the wrist watch 1 and a solar cell light receiving section 3 is arranged at the side thereof. The liquid crystal display unit 2 is provided to display the date and time and the emergency signal transmission status, and the display state of FIG. 1 is a state where the rescue signal has not been transmitted.

Signal transmitting means for transmitting a rescue signal is provided on both left and right sides of the wristwatch 1. Examples of the signal transmitting means include a radio wave transmitting means for transmitting a radio wave, an ultrasonic wave transmitting means for transmitting an ultrasonic wave, and an infrared ray transmitting means for transmitting an infrared signal. The radio wave transmitting means, the ultrasonic wave transmitting means and the infrared ray transmitting means. More specifically, the means are an ultrasonic wave transmitting element 5, an antenna 6 for transmitting a radio wave, and a light emitting element 7 for transmitting an infrared signal, which are sequentially provided from the top of the wristwatch 1.

As a result, in the wristwatch 1 incorporating the rescue signal transmitting device, each of the three types of rescue signals is output from the left and right directions of the wristwatch 1 and has a wide directivity.

Further, a manual switch 8 which can be manually operated is provided on the upper side surface of the wristwatch 1, and when the manual switch 8 is operated, the above-mentioned signal transmitting means is operated by the control means 30 which will be described later. Has become.

FIG. 2 shows circuit components housed inside the wristwatch 1. First, for example, three circuit boards are closely packed in the wristwatch 1, and the upper board is the liquid crystal board 10 on which the liquid crystal display unit 2 and its drive circuit are mounted. As shown in FIG. 3, the substrate is an ultrasonic wave transmission circuit 5a, a radio wave transmission circuit 6a, an infrared transmission circuit 7a.
The transmission circuit board 11 is formed with the respective transmission circuits. A light emitting LED 9 is provided beside the liquid crystal display unit 2 on the liquid crystal substrate 10 so that the display content of the liquid crystal can be confirmed even in the dark.

On the other hand, the transmitter circuits 5a to 7a formed on the transmitter circuit board 11 are connected to the transmitter elements 5 to 7 arranged on the side surface of the wristwatch 1 by wiring.

The lower board is a power supply and control board 12, and the solar cell light receiving section 3 exposed on the surface of the watch is connected to the power supply circuit section on the board 12.

Further, on the substrate 12, a shock detecting means (for example, a shock sensor 21) for detecting a shock, which will be described later, and a life activity detecting means 6 (the life activity detecting means 6 detects a body temperature of a human body, for example). The sensor 22, the perspiration sensor 23 for detecting sweat of the human body, the sensor group of the pulsation sensor 24 for detecting the pulsation of the human body, and the manual switch 8) are further provided.
A control circuit including a microcomputer for processing the input signals from these sensors and activating the liquid crystal display unit 2 and the respective transmission circuits 5a to 7a in accordance with the processing result is provided.

Next, the control circuit of the rescue signal transmitting device will be described with reference to FIG. The rescue signal transmission device includes a sensor group including an impact sensor 21, a body temperature sensor 22, a perspiration sensor 23, and a pulsation sensor 24.

The shock sensor 21 is a sensor for detecting a shock applied to the rescue signal transmitting device. The shock sensor 21 detects this when a constant shock is applied, and can be replaced by an acceleration sensor for detecting acceleration. As the acceleration sensor, for example, a sensor using a surface acoustic wave element (SAW element) is used.

Therefore, when a shock of a predetermined value or more is applied to the human body, it is detected by the shock sensor 21 and, in particular, the house collapses,
When various kinds of disasters such as landslides, avalanches, etc., an extremely large impact (for example, collision, impact, or drop) is applied to the human body, so that a rescue signal, which will be described later, is automatically transmitted based on the output of the impact sensor 21, and the wristwatch 1 Whether or not the wearer is damaged can be determined.

Next, the body temperature sensor 22 comprises a thermistor, is provided on the back surface of the wristwatch 1, and detects the temperature of the arm which is in close contact with this portion. 30 if the wearer is alive
A body temperature of about a degree is detected, and in the case of death, the environmental temperature at the position is detected. Further, the perspiration sensor 23 is also provided at a position in close contact with the wearer like the body temperature sensor 22, and detects the perspiration state of the wearer.

The perspiration sensor 23 detects, for example, perspiration of the human body, and a humidity sensor utilizing a change in resistance value due to moisture absorption can be substituted. In this humidity sensor, for example, a transition metal composite compound such as a porous ceramic (MgCr ₂ O ₄ -TiO ₂ ) in which titanium oxide is added to magnesium chromate is used as a sensor material and has a function as a sensor. To be an element.

When sweating is detected by the sweat sensor 23, it is estimated that the wearer is alive.

Furthermore, the pulsation sensor 24 detects the pulsation of the human body, and more specifically, the pulsation, pulsation, and
It is a sensor that detects a heartbeat and the like, and this sensor is also provided in a position in close contact with the wearer. This beat sensor 24
Detects the pulse when the worn part is the wrist, and detects the heartbeat when the part is the chest. For example, a pressure sensor that applies pressure by contact to detect the dynamic pressure is used.
Since the pressure sensor uses a piezoelectric film that generates an electric charge when a strain is applied in a specific direction, a polymer material that shows an electric field or an electric displacement with respect to stress or strain, etc. as a sensor material, and has a function as a sensor. To be an element. In addition to the pressure sensor, the pulsation sensor 24 irradiates the skin with light of a light emitting diode to change the blood flow thereof, as described in, for example, Japanese Patent Application Laid-Open No. 62-139627. A pulse sensor that detects a phototransistor according to the amount of reflected light may be used instead.

Each sensor 22 to 24 other than the impact sensor 21
Is output to the discriminating means 25 provided for discriminating the presence / absence of life activity of the wearer.

The discriminating means 25 compares the detection output of each of the sensors 22 to 24 with a predetermined content, and as a result, the presence or absence of life activity of the wearer is discriminated for each of the sensors 22 to 24. This determination result is input to the control means 30 which controls the transmission of the rescue signal.

The manual switch 8 and the impact sensor 21 are also input to the control means 30, and based on these signal inputs, whether or not each of the transmission circuits 5a to 7a can be started and the transmission circuits 5a to 7a are activated.
The content of the transmission signal data at the time of start-up is determined, and a command signal corresponding to the result is output to each transmission circuit 5a to 7a and the liquid crystal display unit 2.

The control means 30 and the discrimination means 25 are constituted by a microcomputer, and their control operation is
It is processed by a predetermined program.

The operation of the rescue signal transmission device based on the processing of the control means 30 and the discrimination means 25 will be described below with reference to the flow chart shown in FIG.

First, an initial value 0 is set to a coefficient n for determining the presence or absence of life activity of the wearer (step ST
1). Then, the output of the impact sensor 21 is read, and it is determined whether or not the impact sensor 21 detects a large impact (step ST2).

When the shock sensor 21 is off, that is, when an abnormally large shock is not detected, the process proceeds to step ST3. In step ST3, it is determined whether or not the manual switch 8 is turned on (step ST3). If it is not turned on, the process returns to the first step ST1 again.

On the other hand, when the manual switch 8 is turned on,
Each of the transmission circuits 5a to 7a is activated (step ST
4). The transmission signal data at this time is a repetitive signal (transmission signal No. 1) such as "---".

That is, the same signal "---" is transmitted from the ultrasonic wave transmitting element 5, the radio wave transmitting antenna 6, and the light emitting element 7 which transmits an infrared signal, and this transmission state is maintained. Therefore, even after the disaster, if the wearer is aware, the rescue signal can be transmitted by operating the manual switch 8 by the wearer himself.

On the other hand, when the shock sensor 21 receives a large shock and is turned on, that is, the building collapses on the wearer due to various disasters, the watch 1 incorporating the wearer and the emergency signal transmission device. When a large shock is applied to the wearer, this is detected in step ST2, and the survival status of the wearer is determined in subsequent steps ST6 to ST13, and the signal data of the transmission signal is determined based on this.

First, it is determined whether or not the temperature T _B detected by the body temperature sensor 22 is within the body surface temperature range of the survivor (step ST7). Specifically, the detected temperature T _B is 28 degrees or more 42
It is judged whether it is in the range below the degree. Within this range, it is considered highly possible that the person wearing the watch is still alive. In this case, the coefficient n is set to 1 (step ST8), and the process proceeds to the next step.

On the other hand, if it is out of this range, the coefficient n
No operation is performed to the next step ST9 as it is.
Move to

At step ST9, it is judged if the detection output of the perspiration sensor 23 indicates a perspiration state. If sweating is detected, 1 is added to the coefficient n (step S
T10). If sweating is not detected, no operation is performed on the coefficient n. Subsequently, in step ST11, it is determined whether or not the pulsation sensor 24 detects the pulsation (pulse) of the wearer.

When a pulsation (pulse) is detected, 1 is added to the coefficient n (step ST12). If sweating is not detected, the process directly proceeds to the next step ST13.

At step 13, it is judged if the coefficient n is 2 or more. When the coefficient is 2 or more, each transmission circuit 5a to 7
a is activated, and a repetitive signal of "---" is output (transmission signal No2) (step ST14).

On the other hand, even when the coefficient is 1 or less, the transmission circuits 5a to 7a are activated, but the transmission signal at this time is "-.
It is a repetitive signal of "---" (transmission signal No3) (step ST15).

Therefore, since the signal data of the transmission signal is different when the coefficient n is 2 or more and less than 2, it is possible to refer to the estimation of the survival condition of the victim by analyzing this signal data. be able to.

That is, if any two or more of the body temperature, sweating, and pulsation indicate the survival of the wearer, the repetitive signal of "----" (transmitting signal No. 2) is received. On the other hand, when none of body temperature, sweating, or pulsation shows survival, and when only one shows survival, "--------"
The repetitive signal (transmission signal No. 3) is received.

Therefore, the received signal is the outgoing signal No. Two
In the case of (“−−−−”), the transmission signal No3 (“− ・ −−”)
It is expected that the wearer will have a higher survival rate than the case of "-").

Further, the transmission signal N by the manual switch 8
o. 1 ("---") is signal data different from the case of the automatic transmission by the detection of these impact sensors 21, therefore, the manual operation and the automatic transmission having the highest survival probability from the received signal data. It is possible to identify

6 and 7 show the display state of the liquid crystal display unit 2 when the rescue signal is transmitted. When a signal is transmitted based on the operation of the manual switch 8, a broken line is displayed on the entire lower surface of the time display as shown in FIG. On the other hand, when making an automatic call, an arrow is displayed in this part.

Therefore, the wearer can identify from the liquid crystal display unit 2 whether or not the rescue signal is being transmitted, and whether the rescue signal is being automatically transmitted or manually transmitted.

In this embodiment, three different kinds of signals are output from the ultrasonic wave transmitting element 5, the radio wave transmitting antenna 6, and the light emitting element 7 which transmits an infrared signal. Since these three types of signals have different characteristics as shown in FIG. 8, reachability to the receiver can be increased as much as possible for various situations of the victim.

That is, as shown in FIG. 8, infrared rays are excellent for glass and infrared rays and radio waves are not transmitted to concrete, but ultrasonic waves can be transmitted if the thickness is not so large. . Radio waves and ultrasonic waves are effective for iron materials, ultrasonic waves are highly permeable to wood, and radio waves can also be transmitted depending on their thickness.

Therefore, when the disaster victim and the outside world are shielded by the glass when the house is collapsed, the infrared signal is effective, and in the case of the concrete, the ultrasonic wave is effective. Ultrasonic waves and radio waves are effective for iron and wood.

Further, regarding the signal passing property with respect to a slight gap and the reflectivity with respect to a building material and the like, all of these three types show good characteristics. Regarding the reachable distance, the radio wave is the longest, and the reachable distance becomes shorter in the order of ultrasonic waves and infrared rays.

On the other hand, FIG. 9 shows a rescue signal receiving device for receiving each signal output from the rescue signal transmitting device. This receiving device includes three types of receiving circuits, that is, a radio wave receiving circuit 41, an infrared receiving circuit 42, and an ultrasonic receiving circuit 43, and the reception signals of the receiving circuits 41 to 43 are input to a reception signal processing unit 44. The reception signal processing unit 44 determines the type of the reception circuit that has received the emergency signal and the signal data of the reception signal (transmission signal No1
~ 3) are identified, and the identification result is output to the display unit 45.
The display unit 45 includes six display lamps a to c and 1 to 3,
Which of the signals is received is displayed by the display lamps a to c.

That is, when a radio wave is received, the a lamp is turned on, when an infrared signal is received, the b lamp is turned on, and when an ultrasonic signal is received, the c lamp is turned on.

Therefore, when the disaster victim comes close to the receiving device, all the lamps a to c are turned on.
Further, when the disaster victim and the receiving device are closed by glass, only infrared rays are transmitted, so that the receiving signal of the receiving device is only infrared rays, and only the b lamp is turned on in the display unit 25.

Therefore, the search for the victims can be limited to the collapsed portion with much glass. In this way, an indication of the type of signal received is available specific to the search location of the victim.

Further, by identifying and displaying the signal data of the received signal, it becomes possible to estimate the surviving state of the victim as described above.

Further, the reception level of the reception signal input to the reception signal processing section 44 is detected, and the level is displayed on the reception level display section 46. Therefore, it is possible to determine the direction and distance of the disaster victim with respect to the position of the receiving device based on the change in the reception level when the receiving device is moved in various directions.
