Abstract

PURPOSE:To eliminate a forcible disconnection in the middle of a telephone call and to prevent disaster from expanding owing to the delay of alarm transmission by performing alarm originating operation after letting both subscribers or a caller hear an attention signal tone indicating the generation of an alarm signal during the use of a subscriber telephone or in a called state. CONSTITUTION:When the subscriber telephone 7 is in use and the degree of emergency of a disaster and crime prevention and building facility monitor sensor 1 is high, a control circuit 14 actuates an attention signal tone generating circuit 11 and a timer circuit 17 through an emergency degree signal line 18 to let the subscriber telephone 7 and opposite calling subscriber hear the tone, thus informing them that the telephone call needs to be interrupted because alarm information with a high emergency degree is generated. When, however, the subscribers do not quit the telephone call, the handset of the subscriber telephone 7 is put in the on-hook state electrically with a time limit set in the timer circuit 17 to release the telephone line 9 forcibly and a monitor sensor 4 is called to send the alarm information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic calling device that can take immediate action when alarm information occurs even when a telephone is connected to a subscriber telephone network.

[Conventional technology]

As shown in FIG. 3, it is well known to transfer alarm information for disaster prevention, crime prevention, monitoring of building equipment (elevators, air conditioners, elevated water tanks, etc.), etc. via subscriber telephone networks.

When the disaster prevention/crime prevention/building equipment monitoring sensor 1 in Fig. 3 generates an alarm by closing the contact due to an abnormal condition, the alarm detection circuit 3 in the automatic transmitter 2 detects the alarm, and then automatically transmits alarm information. .

That is, the automatic transmission device 2 sends a telephone number for calling the alarm monitoring center 4 to the exchange system 5 in the form of a dial impulse signal or a pushbutton signal, so that the communication between the automatic transmission device 2 and the monitoring center 4 is caused by the operation of the exchange. line is connected. Next, the line between the automatic transmission device 2 and the monitoring center 4 is connected. Next, the signal transmission device 6 in the automatic transmission device 2 operates to transmit a signal corresponding to a predetermined sensor 1 to the monitoring center 4 in the form of a frequency shift signal, for example, on a telephone line. Therefore, the monitoring center 4 can immediately detect where and what abnormality has occurred. At this time, since the line between the automatic calling device 2 and the switching system 5 is shared with the subscriber telephone 7, when the telephone 7 is in use by talking to another telephone 8, alarm information is generated. However, the monitoring center 4 could not be automatically called, and there was a risk that warning transmission would be delayed, leading to serious consequences.

Therefore, as a means to solve this problem,
An automatic transmission device disclosed in Japanese Patent No. 061 has been proposed and put into practical use.

[Problems to be Solved by the Invention] In the above-mentioned prior art, when alarm information is generated while the subscriber telephone is in use or while a call is being made, both parties on the call or the caller hear a warning signal sound to notify that the alarm information has occurred. This creates an on-hook state for the handset. Therefore, line release is left to the subscriber phone user. Therefore, if a fire occurs in a timely manner, the alarm information cannot be determined to be a fire just by hearing the warning signal sound, and calls may not always be stopped immediately, resulting in a delay in the transmission of the alarm, resulting in a catastrophe. could have serious consequences.

The purpose of the present invention is to improve the above-mentioned drawbacks, and to prevent alarm information from occurring even when the telephone subscriber is preparing to make a call or is in the middle of a call.
It is an object of the present invention to provide an automatic transmission device that can take immediate action depending on the urgency of alarm information.

[Means to solve the problem]

In order to achieve the above object, the automatic transmission device of the present invention includes:
The automatic transmitter is equipped with a caution signal sound generation circuit, an automatic reception circuit, an identification circuit for identifying highly urgent information among alarm information, a timer circuit, and their control circuits, and the telephone on the alarm information transmitting side is used for reporting. When the alarm detection circuit is activated during the operation, the attention control circuit detects it and operates the attention signal sound generation circuit while the circuit is held, and when the alarm detection circuit is activated during the call due to an incoming call. If the automatic reception circuit automatically responds and the control circuit detects the operation, the control circuit operates the warning signal sound generating circuit to notify the caller or caller of the warning signal, respectively, and the When the information is identified, the control circuit activates the timer circuit to make the line idle after a predetermined period of time, and sends an alarm signal to the line after the control circuit confirms that the circuit is idle. It is.

[Effect]

In the present invention, when alarm information in a disaster prevention/crime prevention/building/equipment monitoring system occurs while a subscriber telephone is in use or while a call is being made, the control circuit detects the alarm information identified by the emergency level identification circuit and maintains one circuit. If both parties on the call or the caller hear an alert signal indicating that alarm information has occurred, and the alarm information is highly urgent, the control circuit activates a timer circuit and releases the line after a predetermined period of time. Automatically send alarm signals to the monitoring center. Therefore, it is possible to reliably prevent a catastrophe caused by a delay in alarm transmission, which can occur when highly urgent alarm information occurs while a subscriber telephone is in use or while a call is being made, as in conventional automatic transmission devices. became.

．． The control circuit 14 detects that the communication line 9 has been released, and the control circuit 14 switches the line switching circuit 12 to the signal transmission device 6. The control circuit 14 can then activate the automatic transmission circuit 15 to call the monitoring center 4 and transmit alarm information.

When the subscriber telephone 7 is in use and the emergency level of the disaster prevention/crime prevention/building equipment monitoring sensor 1 is high, the control circuit 14 activates the warning signal sound generation circuit 11 and the timer circuit 17 via the emergency level signal line 18. Then, the subscriber telephone 7 and the other party are informed of the necessity of interrupting the call by letting them hear a warning signal sound from the warning signal sound generating circuit 11, as alarm information with a high degree of urgency has occurred. However, if the subscriber who is talking does not interrupt the call, the handset of the subscriber telephone 7 is electrically placed on-hook within a preset time period by the timer circuit 17, and the telephone line 9 is forcibly released. Then, the control circuit 14 activates the automatic transmission circuit 15 to call the monitoring center 4 and transmit alarm information.

When the alarm detection circuit 3 detects the occurrence of an alarm, the subscriber telephone 7
When the control circuit 14 detects that the telephone line 9 is not in use, the control circuit 14 immediately sends a switching signal to the line switching circuit 12 to connect the telephone line 9 to the signal transmission bag @6 side. At this time, the automatic reception circuit 13 is connected to detect the presence or absence of a 16 Hz ringing tone. After switching the line switching circuit 12.

The control circuit 14 waits for a detection signal from the automatic reception circuit 13, and if it is not detected after a predetermined period of time has elapsed, the telephone 7 is not in use and is not being called (the telephone line 9 is in an open state). ), the control circuit 14 starts the automatic transmission circuit 15 and calls the monitoring center 4. Subsequently, alarm information is sent out in the same manner as described above.

If the automatic reception circuit 13 detects a 16Hz ringing tone, the automatic reception circuit 13 creates a DC closed circuit in the same state as when the handset is on-hook and responds to the exchange. timer circuit 17. By activating the caution signal generation circuit 11, the caution signal is made to be heard by the caller.

Therefore, since the caller cannot start a call, the caller puts the handset on-hook, and in the case of alarm information with a high degree of urgency, the control circuit 14 puts the handset in the same state as on-hook after a predetermined period of time, so that the alarm information can be transmitted. Become.

According to this embodiment, when alarm information is placed on the subscriber telephone network, a caution signal tone is heard by both parties or the caller even when the subscriber telephone is in use or being called;
