Abstract

PROBLEM TO BE SOLVED: To prevent an alarm from being reported to the outside even when a transmission button is erroneously pressed or a receiver malfunctions owing to strong interference radio waves by receiving control signals from a center by a control signal receiver and operating an alarm device by the reception output of the control signal receiver. SOLUTION: A user carrying a radio transmitter 1 presses the push button of the radio transmitter 1 at the time of emergency. Transmitted radio waves are received by the radio receiver 4 of an emergency reporting fixed device 2 through an antenna 3. The output of the radio receiver 4 is sent to a control part 5 and the control part 5 operates a telephone set 7. The control part 5 calls a telephone number, when an emergency breaks out, of the center or the like from a public telephone line from the telephone set 7. A helper who communicates with the user in the emergency and recognizes the contents of the emergency sends out the control signals from the telephone set at the time of judging that it is truly the emergency with no time to lose. The control signals are received by the control signal receiver 8 and operate the alarm device.

I will provide a.

Embodiments of the present invention will be described below in detail. FIG. 1 is an example of a block diagram of an emergency notification method having a remote control function according to the present invention. The wireless transmitter 1 has a push button, and when the button is pressed, a radio wave is transmitted for a fixed time or for a pressed time. If the wireless transmitter 1 is made small, it can be carried around at all times by hanging it from the neck or putting it in a pocket. The user carrying the wireless transmitter 1 presses a push button of the wireless transmitter 1 in an emergency. The transmitted radio wave passes through the antenna 3 and is received by the wireless receiver 4 of the emergency call fixing device 2.
The output of the wireless receiver 4 is sent to the control unit 5, and the control unit 5 operates the telephone 7. The control unit 5 transmits a telephone number to be contacted when an emergency occurs, such as a center, from the telephone 7 from a public telephone line. This phone number is
And may be stored in the control unit 5. At the center where the call arrives, a helper or the like waiting in response to the emergency responds, and the user conveys the details of the emergency. In an emergency situation, it is considered that it is often impossible for the user to hold the handset of the telephone 7, so the telephone 7 is desirably a hands-free phone or the like. The center helper who talks with the user in an emergency and learns the contents of the emergency transmits a control signal from the telephone when it determines that the emergency is truly urgent. This control signal is received by the control signal receiver 8. As the control signal, it is convenient to use a push button signal of a push phone or the like. In that case, the control signal receiver 8 becomes a push button signal receiver. Of course, when the public telephone line is ISDN, a digital signal of ISDN can be used as the control signal. The control signal receiver 8 is connected to the control unit 5, and when the control signal is received, the control unit 5 issues an alarm 6
To work. The alarm device 6 includes a sound unit including a bell, a buzzer, or a sound generating device for reporting an emergency, and a light-emitting unit such as a rotating red lamp. Notify the neighborhood that the situation is happening.

FIG. 2 shows a control flow of the control unit 5 in this case. In FIG. 2, the control unit 5 transmits the radio wave to the radio receiver 4.
(STEP 21: NO loop). If radio waves are received (YE in STEP 21)
S) The telephone 7 automatically sends out the telephone number of the center stored in advance and calls the center (STEP 2).
2). The center responds and the call line is set (STEP
23), the call between the user and the center helper is enabled, and the helper determines whether the user is truly an emergency. In the case of a truly emergency, the helper sends out a control signal. This can be done simply by pressing a particular push button on the telephone. When not in an emergency, talk to the user and disconnect. Meanwhile, the control unit 5 checks whether the control signal or the telephone line is disconnected (NO in STEP 24 and NO in STEP 26). If a disconnection signal is received (YES in STEP 26)
Return to the beginning. If the control signal is received (YES in STEP 24), the alarm device 6 is operated (STEP 25).
After the alarm device 6 is activated, if possible, the alarm device 6
Is confirmed by sound, and the line is disconnected (NO in STEP 24 and YES in STEP 26). When such control is performed, even if the user presses the transmission button of the wireless transmitter 1 by mistake, the center helper makes a call and checks whether or not the emergency is truly urgent. , So that there is no inconvenience caused by misinformation to the neighborhood. In addition, even when the user becomes lonely and presses the transmission button, the helper can talk to the neighbor without operating the alarm device 6 that is a notification to the neighborhood, so that the feeling of the user can be eased.

However, in this method alone, if the transmission button is pressed by mistake, the operation of the alarm device to the neighborhood can be avoided, but the telephone call to the center by mistake cannot be avoided. In order to avoid an erroneous call to the center, there is a block diagram shown in FIG. 3, a preliminary alarm device 9 and a timer device 10 are added to the components shown in FIG. That is, the preliminary alarm device 9 as the first alarm device
The alarm device 6 of FIG. 1 is connected as a second alarm device. The alarm device 6 is for communicating an emergency to the neighborhood, while the preliminary alarm device 9 is installed indoors,
It informs the user that the send button has been pressed. FIG. 4 shows a control flow of the control unit 5 corresponding to FIG. The control unit 5 always waits for the reception of the radio wave by the radio receiver 4 (NO in STEP 31). When the user presses the transmission button of the wireless transmitter 1 and the wireless receiver 4 receives the signal (YES in STEP31), the control unit 5 activates the standby alarm device 9 and starts the timer device 10 (STEP32). The preliminary alarm device 9 is provided with a buzzer for indoor use, and "The emergency call button has been pressed.
After 30 seconds, a call will be made to the center. If you make a mistake, please press the send button again. "Or a flashing light for people with a hearing loss. It is checked whether or not the wireless receiver 4 has an output again within a predetermined T seconds after the timer device 10 is started (STEP 33 and NO loop of STEP 37). Assuming that T is 30 seconds, for example, the user
When the preliminary alarm device is operated by an indoor buzzer or sound, if the user presses the transmission button by mistake, the user presses the transmission button again within 30 seconds. If there is an output from the wireless receiver 4 (YES in STEP 33), the user has pressed the send button again, so both the operation of the standby alarm device 9 and the activation of the timer device 10 are stopped (STEP 38). Return to If there is no reception output and T seconds have elapsed (YES in STEP 33), the operation of the standby alarm device 9 that has been operating is stopped, and the timer device 10
Is reset, the telephone 7 is operated, and the telephone number of the center stored in advance is transmitted (STEP 35). When the telephone line is connected to the center (STEP 36), the control unit 5 checks whether the control signal receiver 8 receives a control signal from the center (STEP 39). The user and the center helper talk, and if the helper determines that the situation is truly emergency,
The helper sends out a control signal. If the helper determines that the call is not urgent, the call is terminated without sending a control signal. That is, the control unit 5 checks whether a control signal comes from the center (STEP 39) or whether the telephone line is disconnected (NO in STEP 39 and STEP 37).
NO loop). If the disconnection signal comes (STEP 3
7 (YES), control returns to the beginning. If a control signal is received (YES in STEP 39), the alarm device 6 is operated (STEP 41), and the flow returns to the flow of checking whether a control signal or a disconnection signal is received again (STEP 39).

As described above, in the control flow of FIG. 4, even if the transmission button is pressed by mistake, the emergency call is made by the buzzer sound of the auxiliary alarm device 9 installed in the room, the sound or the blinking of the lamp, and the like. If you know that the device is in operation, and if it malfunctions, press the send button again within a predetermined period of time, for example, within 30 seconds, the telephone number to the center will not be sent automatically, so Don't bother.

In the control flow shown in FIG. 4, when the transmission button is pressed, and after a certain period of time, the telephone 7 is operated to make a call to the center, and the helper of the center determines whether or not the alarm 6 is to be operated. 6, but has some drawbacks. In other words, this method requires that the telephone be connected to the center without fail, but there is a problem that the alarm device 6 does not operate unless the telephone is connected to the center due to a busy telephone line or a failure in the exchange. That is, even in a truly emergency situation, the alarm device 6 is not operated, and the function of the emergency notification device cannot be performed. As a countermeasure in such a case, when the center is busy or there is no response for a certain period of time, it automatically dials another stored phone number and calls another center or relatives' house, or after a while It is desirable to redial. However, when the telephone line at home is out of order, the alarm device 6 is not operated. For this reason, there is a method in which the alarm device 6 is forcibly activated when a state in which a call is not made to a partner is continued for a certain time or a certain number of times even when the telephone number of the center or a relative is automatically transmitted.
As another method, the timer device 10 is activated and T
After a few seconds, there is a method of operating the alarm device 6 and calling the center. FIG. 5 shows a control flow in the latter case.

In the control flow of FIG. 5, if there is a reception output (YES in STEP 31), the standby alarm device 9 is operated,
The timer device 10 is started (STEP 32), and it is checked whether T seconds have elapsed (STEP 33). In the meantime, if the reception output is again (NO at STEP 37), the operation of the preliminary alarm device 9 is stopped, and the timer device 10 is reset (STEP 37).
38). When T seconds elapse without receiving data again (ST
(YES in EP33), and activates the alarm device 6 (STEP 3).
4) The center number is transmitted from the telephone (STEP 3).
5). In FIG. 5, a step of operating the alarm device 6 (STEP 34) is added to the control flow of FIG. That is, the alarm device 6 is connected to the center at the same time.
Is activated to alert the neighborhood. It is connected to the center (STEP 36) and talks with the helper at the center. If the helper determines that it is urgent, it does not send any control signal (NO at STEP 39) and disconnects (STEP 4).
0), a helper runs from the center to the user's home. If it is not so urgent, the helper sends a control signal from the center, the control signal is received by the control signal receiver 8 (YES in STEP 39), and the operation of the alarm device 6 is stopped (STEP 42).

As described above, in the control flow of FIG. 5, the alarm device 6 is operated first, and then, when it is determined that the helper is not urgent, a control signal is transmitted to stop the operation of the alarm device 6. Even if the telephone line to the center is out of order, the alarm device 6 can operate. Of course, in this case, the center helper does not judge whether or not the emergency is a real emergency, but a situation where the alarm device 6 is not operated in the event of a truly emergency can be avoided, and the system can operate in a fail-safe manner. .

Further, it is expected that an emergency will occur in which the user cannot press the send button.
There is no method that can always deal with such a situation, but if the danger is predicted to some extent, there is a method of periodically accessing the emergency device from the center. FIG. 6 shows the control flow. In FIG. 6, the control unit 5 checks whether there is an incoming call on the telephone 7 (STEP 51). When the helper calls the telephone 7 from the center, the telephone 7 is received (YES in STEP 51), and the telephone 7 is answered by the user or automatically answered, and the telephone 7 enters the talking state (STE).
P52). The control unit 5 checks whether the control signal is received by the control signal receiver 8 from the center or the line is disconnected (a loop including NO in STEP53 and NO in STEP54). The center helper talks to the user and checks if it is an emergency. When the helper determines that the user is in an emergency situation, for example, in a state where the user is suffering or can hardly talk, the center sends a control signal. When this control signal is received by control signal receiver 8 (YES in STEP 53), alarm device 6 is operated (STEP 53).
EP55), notifies the neighbor of the emergency situation. If it is determined that the helper is not in an emergency state, the control signal is not transmitted (NO in STEP53), and the line is disconnected (STEP5).
(YES at 4) Return to the beginning. With such control, the helper can know the emergency situation of the user who could not press the transmission button of the wireless transmitter 1 in the emergency situation, and can operate the alarm device.

In the block diagrams of FIGS. 1 and 3 used in the above description, the control unit 5 can be configured by using a microcomputer or the like, but can also be performed by a simple switch.
That is, if there is an input to the wireless receiver 4, the terminal of the switch activates the preliminary alarm device 9 or the timer device 10
It is easy to start. If the timer device 10 is constituted by a delay circuit, an output is output after a certain period of time after the timer device 10 is activated by a switch, so that the telephone 7 is operated with the output and stored in the memory of the telephone 7. Send a phone number. The control signal receiver 8 is also a push button signal receiver, and can be easily realized such that a signal of a push phone is used as a control signal, and when the signal is received, the alarm device 6 is operated with a received output. In addition, telephone 7
Although the control signal receiver and the control signal receiver are described separately, the control signal receiver 8 may be integrated with the telephone 7.

Further, the control flow arriving from the center shown in FIG. 6 can be used in combination with each control flow shown in FIGS. That is, at the beginning of the flow,
"Whether there is an output from the wireless receiver 4" (STEP 21 or ST
EP31), and the determination unit "whether there is an incoming telephone call"
It is possible to provide both of the determination units (STEP 51) and shift to the respective flows if either is provided.

According to the present invention, the following effects can be obtained. (1) Even if the transmitter button is pressed by mistake in an emergency, the center helper operates the alarm device for the neighborhood, so that there is no malfunction and no trouble is caused to the neighborhood. (2) By using the backup alarm device, it is possible to prevent erroneous connection to the center. (3) Since an incoming call is received from the center and the urgency of the user is checked, rescue can be achieved even when the transmission button of the wireless transmitter cannot be pressed.
