Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency notification device for automatically making a notification to a contact by voice message using a telephone line when an abnormality is detected.

[0002]

2. Description of the Related Art A conventional signal communication procedure of this type of emergency notification device is shown in FIG. When a sensor (not shown) detects an abnormality, the emergency notification device automatically sends a dial signal via the PSTN (telephone line). When the dialed signal arrives at the call destination telephone and the call destination telephone answers, the polarity of the telephone line is reversed. A reversal detector (not shown) of the emergency notification device detects this reversal of polarity and confirms the response of the destination telephone. When the emergency notification device confirms that the destination telephone has responded, it sends a voice message informing the emergency. When the response of the other party is not confirmed, the second or third report destination is reported, or the same report destination is repeatedly redeemed to automatically report the abnormality. The emergency call device confirms the response of the callee by reversing the polarity of the telephone line as described above, and if a predetermined message is sent, the telephone line is released and the call is terminated.

[0003]

However, in the conventional apparatus, even when an automatic answering machine such as an answering machine is connected to the callee, the polarity reversal of the telephone line is detected and it is considered that the other party responded, and a message is displayed. Is sent and the notification ends. Therefore, there is a problem that an urgent message may not be transmitted to the other party who understands the content of the message of the emergency notification and can perform appropriate processing, and the processing to deal with it is delayed.

The present invention has been made in view of the above-mentioned points, and eliminates the above-mentioned problems and identifies whether or not the response from the callee is from an appropriate responder at the time of an emergency call, and reliably determines the response. It is an object of the present invention to provide an emergency notification device capable of transmitting a message to the other party.

[0005]

In order to solve the above-mentioned problems, the present invention receives an abnormal signal from a sensor 3 for detecting an abnormal condition as shown in FIG. 1 and sends a voice message to a predetermined telephone receiver 2 as a destination. In the emergency call device 1 for making a notification, a PB signal (push button signal) receiving unit 1-5 is provided, and when a predetermined PB signal is received by the PB signal receiving unit 1-5 from the other party and is detected, it is reliably transmitted to the other party. If the presumed report operation is terminated and the predetermined PB signal cannot be received,
A means for continuing the notification operation until the other party considers it to be unresponsive and receives a predetermined PB signal is provided.

[0006]

In the present invention, a predetermined PB signal is arranged in advance between the sender and the person in charge of the contact, and the emergency call device automatically sends a predetermined voice message during an emergency call,
By receiving the reply of the predetermined PB signal from the contact, it is confirmed that the message has been transmitted to the intended other party and the notification is terminated. Therefore, the message can be surely transmitted to the other party.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the emergency notification device of the present invention. As shown in the figure, the emergency call device 1 of the present invention includes a storage unit 1-which stores information such as a telephone number of a call destination.
1. CPU (Central Processing Unit) 1-2 that controls each part to perform various processes; voice synthesis sending part 1-3 that creates a voice message; dial sending part 1 that sends a dial signal.
4. A PB signal receiving unit 1-5 that receives a predetermined PB signal from the callee, a hybrid circuit 1-6, and an inversion detection unit 1-7 that detects inversion of the polarity of the telephone line. When an abnormality is detected by the sensor 3, the abnormality detection signal is activated and a message indicating the emergency is sent to the destination telephone set 2.

FIG. 2 is a diagram showing a signal communication procedure of the emergency notification device of the present invention. The operation of the emergency notification device 1 will be described with reference to FIGS. 1 and 2. When an abnormality occurs, the abnormality signal detected by the sensor 3 is input to the CPU 1-2 of the emergency notification device 1. The CPU 1-2 commands the dial sending unit 1-4 to perform automatic dialing according to the notification destination registered in advance in the storage unit 1-1. The dial sending unit 1-4 sends a dial signal to the telephone receiver 2 via the hybrid circuit 1-6 and the telephone line.

When the dial signal is received by the call destination telephone 2 and the call destination telephone 2 answers, the polarity of the telephone line is reversed. The reversal of the polarity is detected by the reversal detection unit 1-7 of the emergency notification device 1 to detect the reversal of the polarity, and the CPU 1-
Notify 2. The CPU 1-2 instructs the voice synthesis sending unit 1-3 to send a predetermined message to notify the emergency. The voice synthesizing and sending unit 1-3 sends a predetermined message to the destination telephone 2 via the hybrid circuit 1-6 and the telephone line.

After a certain time has passed after the above message was sent, PB
When the signal receiving unit 1-5 receives the predetermined PB signal from the telephone 2 to be notified, it notifies the CPU 1-2. CPU1-2
Judges that the above message has been transmitted to the other party who needs it, terminates the processing and releases the telephone line. After sending the above message,
When the PB signal cannot be received from the other party even after the stipulated time has elapsed, the same automatic notification is repeated to the next report destination.

The method of transmitting a predetermined PB signal for notifying the arrival of a message from the call destination telephone 2 is performed by the side issuing the emergency call (emergency call device 1) and the side receiving the emergency call (call destination phone 2). The method of predetermining the PB to be pressed when receiving and receiving the message to notify the emergency between the time and the message during or after sending the message to notify the emergency, for example, "If this message is received and acknowledged XX
Please press PB. , ”And a message to the effect that a predetermined PB is pressed. In short, at the time of an emergency call, it is possible to judge whether the response from the callee is not from the automatic response device, but from the appropriate responder.
It may be a B signal. Also, as a basic operation example, when the other party responds, "Fire out, fire out, ...
・ ”Message is sent for a specified time. When the PB signal is received while sending this message, "This is XXX. Please come soon. , Etc., a message with detailed contents is sent, and after sending, the communication ends (normal end). Even when the specified time is exceeded, a message with the same detailed content is sent (however, in this case, the other party does not respond).

FIG. 3 is a diagram showing another signal communication procedure of the emergency notification device of the present invention. The difference between this signal communication procedure and the signal communication procedure of FIG. 2 is that the callee responds to the incoming call and at the same time, sends a predetermined PB signal to the emergency notification device 1, and the emergency notification device 1 reverses it. The detecting unit 1-7 detects the polarity inversion, and the PB signal receiving unit 1-5 detects the PB signal.
When receiving the signal, the CPU 1-2 is notified. CPU1
-2 instructs the voice synthesis sending unit 1-3 to send a predetermined message notifying that the message destination is in a state where the message can be judged. The voice synthesis sending unit 1-3 sends a predetermined message to the destination via the hybrid circuit 1-6 and the telephone line. When transmission of the message ends, the telephone line is released and the call ends.

FIG. 4 is a diagram showing another signal communication procedure of the emergency notification device of the present invention. This signal communication procedure differs from the signal communication procedure of FIG. 3 in that the emergency notification device 1 does not detect polarity reversal, and when the PB signal receiving unit 1-5 receives the PB signal from the destination telephone set 2, This is a point for instructing the transmission of a predetermined message.

[0014]

As described above in detail, according to the present invention, the following effects can be expected. A predetermined PB signal is arranged between the sender and the person in charge at the receiver, and the emergency notification device receives a reply of the predetermined PB signal from the receiver at the time of an emergency call so that a message can be sent to the necessary party.
