A signal detection unit 9 for detecting a push signal and the like is provided.

With such a configuration, the wireless emergency call system according to the present invention operates as follows.

By operating a button on the wireless transmitter 10, a wireless signal is transmitted, and when the receiver 20 receives this wireless signal, it transmits an abnormality detection signal to the controller 1 via the signal line L.

In the controller 1, when the abnormality detection signal is received from the receiver 20, the notification control unit 2 sequentially reads the dial numbers stored in the notification destination number storage unit 3 and repeatedly calls (cyclic redial).
When one of the telephones T1 to Tn receives the call, the message output unit 4 causes, for example,
A notification message such as "This is XX. An abnormality has occurred. Please check immediately." Is output, but if you do not receive a call due to busy or out of office even after calling for a predetermined time (for example, 30 seconds), this dial Suspend a call to a number and call the next dialed number. When there are a plurality of callees, priority may be set in the order of calling by the call control unit 2.

When calling any of the callees, even if one of the telephones T1 to Tn receives a call and outputs a call message, the callee may be an answering machine or the message may not be accurately transmitted. If there is no operation by the person who confirms the message, the call is repeated.

The operation method for stopping the call will be described below. Since this method can notify the incoming telephones T1 to Tn together with the notification message by the message output unit 4, the operation method will be described in advance. Even a stranger can easily stop calling.

The first method is a method executed by the controller 1 side, and the call by the notification control unit 2 is stopped by operating the notification stop switch 7a.

The second method is a method of executing a call from the telephones T1 to Tn that have received a call. Dial operation, push button operation, or automatic signal transmission to call by the notification control unit 2. To stop. This is performed by the signal detector 9 of the controller 1 detecting a predetermined signal for stopping the call. Telephone line L
When 1 is an analog line, a tone signal or dial pulse signal is used to give an instruction to stop calling, and when the telephone line L1 is a digital line, a push signal is used to give an instruction to stop calling.

2 and 3 are timing charts showing an example of the basic operation of the system of the present invention described above.

2A to 2G show the case where the call is stopped by the notification stop switch 7a.

A wireless signal is sent from the wireless transmitter 10, and the receiver 20 that receives this wireless signal sends an abnormality detection signal to the controller 1 (a)-
(D). The controller 1 repeatedly calls the call destinations (A to D) in sequence, but when the report stop switch 7a is operated during the call, the call is stopped (e) to (g).

In FIGS. 3A to 3K, the tone signals transmitted from the telephones T1 to Tn of the notification destination are
The case where the call is stopped is shown.

The controller 1 is composed of (a) to (d) in FIG.
Similarly, when an abnormality detection signal is received from the receiver 20, the callees (A to D) are repeatedly called in sequence (e), (i), for example, the callee A receives a call. When a tone signal is received from this notification destination A after outputting a notification message to this notification destination A (f), (j), a stop signal is output inside the controller 1 to stop the call (g). , (H), (k).

In this way, repeated calls can be stopped, but when the called party is an answering machine or a communication terminal other than the telephone, these are excluded from the call target. Then, subsequent calls can be repeated.

To determine that the other party is an answering machine,
This is performed by the absence recording start sound detected by the signal detection unit 9 after the incoming call. When the called party is an answering machine, generally, after receiving an answering message after receiving an incoming call, an answering recording start sound such as "pee" prompting the input of a message is received. As a result, the controller 1 side stores this fact, and the message output unit 4 outputs a notification message and records it as a message message, and then continues to call other notification destinations. At this time, since the controller 1 stores the callee which is the answering machine as described above, the callee can be excluded from the call target.

Further, the discrimination as a communication terminal other than the telephone is performed by detecting a reply signal such as a facsimile communication procedure signal by the signal detecting section 9 after the incoming call from the difference in frequency. In this case, the notification message is not output, but the call to other report destinations is continued and this communication terminal is excluded from the call target.

FIGS. 4A to 4I are timing charts showing an example of the operation when one of the call destinations is an answering machine.

The controller 1 is composed of (a) -FIG.
When an abnormality detection signal is received from the receiver 20 in the same manner as in (d), the call destinations (A to D) are repeatedly called in sequence (e) and (h). For example, the call destination D is an answering machine. It is a telephone, and after receiving an answering recording start tone after receiving a call and recording a notification message, (f), (g), (i), the callee D is excluded from the call target, and the call is resumed ( e), (h).

[0038]

As can be understood from the above description, according to the wireless emergency call system of the present invention, when making an emergency call to a previously registered addressee, the addressee may be busy or out of the office. However, since the call is repeatedly made until the person who confirms the notification message performs any operation, it is possible to reliably notify the abnormality to the notification destination via the telephone line.

According to the first to fourth aspects, since the call can be stopped from the telephone set via the telephone line as the report destination, the call to the other report destination and the re-call to the own telephone set are prevented. You can

According to the fifth aspect, since the method of stopping the call is notified to the incoming telephone or the like by the voice message, the operation for stopping the call again can be easily performed.
