Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm transmission/reception system, and in particular, it transmits alarm information from a plurality of alarm transmitting devices and receives it via a telephone switching network, thereby transmitting various situations occurring in remote locations. This invention relates to an alarm transmission/reception system for centralized monitoring.

As this type of alarm transmission/reception method, security start information 2w: preparation end information, fire,
There is a system that centrally monitors security information such as theft, intrusion, abnormalities in equipment, etc. by receiving it at one location via an exchange network. The security receiving device using this system is equipped with an indicator light for each security destination to indicate the status of the security destination and whether or not a security notice has been received, and is capable of displaying the received security information and printing a record on a printer. Is going.

When such a receiving device receives security information, one piece of security information is received in one reception. Therefore, when the sound type sending device transmits multiple security information generated at the same time, in order to transmit only the one with the highest priority among the multiple security information, or to transmit all the multiple security information, It is now possible to automatically dial multiple times and send security information that occurs simultaneously.

For this reason, it is possible to receive only high-priority pieces of security information that occur simultaneously, or it takes time to receive all the security information when receiving multiple security information at the same time. There are drawbacks.

SUMMARY OF THE INVENTION Therefore, the present invention has been made in order to eliminate the shortcomings of the conventional methods, and an object of the present invention is to provide an alarm transmission/reception method that can receive all simultaneously generated security information in a short time. It is said that

The alarm transmitting/receiving method according to the present invention is configured such that when at least two pieces of security information to be transmitted occur substantially simultaneously, the alarm transmitting device transmits continuation information indicating the continuation of the next information following the security information of cylinder 1. At the same time, the alarm receiving device determines whether there is continuation information or not. The present invention is characterized in that a security transmission request is issued to the alarm transmitting device when this continuation information is detected.

FIG. 1 is a block diagram of one embodiment of the υ information receiving device of the present invention, in which network control units 1 and 2 are connected to a plurality of monitoring terminal devices via telephone lines AT and A2 via an exchange. After receiving a call signal from the exchange, the call is automatically received, and at the same time, a gradual response signal indicating that the line has been connected to the monitoring terminal device on the calling side is output, and at the same time, multi-frequency reception is sent to the reception control unit 3. The multi-frequency receiver 4 receives the device use request signal 21-1 and 21-2.
Make a request for use. If the multi-frequency receiver 4 is usable, the reception control unit 3 sends a multi-frequency receiver use permission signal 22- to the multi-frequency receiver use request signals 21-1 and 21-2 from the network control units 1 and 2. 1 or 22-2 to enable reception of monitoring information. When the network control units 1 and 2 receive the multi-frequency receiver use permission signal 22-1, 22-2, they send a transmission request signal to the alarm transmitting device in order to have the device transmit monitoring information.

The reception control unit 3, which is now able to receive the security information, receives the terminal number received by the multi-frequency receiver 4 and starts security.

Security information such as end of security, fixed call, fire, theft, water level, etc. is recorded on a 4-bit B CD (Binary Coded D).

Then, if the multi-frequency signal of the last digit among the preset digits in the received security information is an end signal, it is determined that the reception of the security information has ended, and the network control unit 1
A reception end signal 23-1.23-2 is sent to ゜2.

If the multi-frequency signal of the last digit of the preset digits in the received security information is the next information continuation signal, it is determined that the security information is still being received, and the network controllers 1 and 2 are notified of the next information. Send request signal 24-1.24-2. Moreover, if a multi-frequency signal other than the end signal or the next information continuation signal is received at the last digit of the preset digits, it is determined that a data error has occurred, and the data error signal 25-1 is sent to the network controllers 1 and 2. Send ゜25-2.

When the network control units 1 and 2 receive the reception completion signal 23-1 and 23-2, they send a confirmation reception signal to the light transmitting device, open the line on which communication has been carried out, and wait for a call from the monitoring terminal device. becomes. However, the next information request signals 24-1, 24. −
2, the alarm transmitter sends a next information transmission request signal to the confirmation signal and waits for the next information to be received.

Also, upon receiving the data error signal 25 1, 25 2, the communication line that has been used up until now is immediately released, and the system waits for a re-call from the alarm transmitting device. The security information analysis unit 5 receives the BCD coded monitoring information from the reception control unit 3, and if it is the start of security, it sends a time monitoring start signal 26 to time monitoring corresponding to each terminal device of the scheduled transmission time monitoring unit 6. Start the timer, and when the security ends, the time monitoring stop signal 27
to stop the time monitoring timer. Further, when the security information analysis section 5 identifies a signal other than start of guarding or end of guarding, it sends a time monitoring reset signal 28 to reset the time monitoring timer and restart time monitoring.

The scheduled transmission time monitoring section 6 monitors the time using a time monitoring timer corresponding to each terminal device, and the scheduled transmission signal 29 and the terminal number 30 are received by the security information analysis section 5 within the normal reception range.
When given, it resets the time monitoring timer and starts time monitoring again.

In addition, when the security information analysis section 5 receives a regular transmission signal with a short interval outside the normal reception range, the regular transmission time monitoring section 6 resets the time monitoring evening 4 timer and starts time monitoring again. The outgoing abnormality signal and the security destination number are sent to the print display control section 7. Alternatively, if the normal reception range is established and the regular transmission signal 29 and terminal number 30 are given from the security information analysis unit 5, or if the regular transmission signal cannot be received, the monitoring terminal abnormality signal and the security destination number are printed. It is sent to the display control section 7.

In the print display control section 7, regularly transmitted abnormal print signals generated under each of the above-mentioned situations are transmitted.

When the security terminal abnormality signal and each security destination number are received from the scheduled call time monitoring section 6, the display interface 8
．． The images displayed on the display unit 10 via the printing interface 9 are printed and recorded on the printer 11.

Further, when receiving security information other than the scheduled transmission signal received from the security information analysis section 5, it is displayed on the display unit 10,
The printer 11 is caused to print and record. The clock part 12 is
