A line 4 is connected to each repeater 3, and each line 4 is connected to a smoke detector, heat sensor, etc. that transmits analog signals such as current level and voltage level to the repeater 3 according to sensing operation. disaster prevention sensor 5
is connected. Receiver 1 sends a transmission signal consisting of a pulse code signal including an individually assigned address signal to each repeater 3 via main line 2, and repeater 3 detects that the address signal matches its own address. At times, the transmission signal is taken in, and an address signal from a disaster prevention sensor 5 connected to the line 4 is converted into a pulse code signal, which is then sent back to the receiver 1 via the main line 2 as a transmission signal. The receiver 1 performs judgment control such as the occurrence of a fire, a forecast, etc. based on the address signal converted into a pulse code signal.

１からの指令が不要となる。[Disclosure of the Invention] FIG. 1 shows a circuit configuration of a repeater 3 used as an embodiment, and the repeater 3 sets a judgment reference level for discriminating analog signals from a disaster prevention sensor 5 connected to a line 4. Standard setting section 6
and a determining unit 7 that compares the set reference level of the standard setting unit 6 with an input analog signal to determine whether a fire has occurred or a forecast, and based on the determination result of the determining unit 7, a driving signal for an alarm bell, An output unit 8 that generates an output S such as a control output for smoke prevention control, and a determination unit 7
A signal converter 9 converts the determination result into a pulse code signal, and a signal that determines whether the address matches when receiving the transmission signal and controls each unit, and sends out the output of the signal converter 9 as a return signal. It is composed of a processing section 10. FIG. 2 shows the overall configuration of a disaster prevention system using the receiver 3 described above. When the address signal matches its own address, the repeater 3 takes in the above-mentioned transmission signal, and transmits the judgment information based on the state of the disaster prevention sensor 5 connected to the line 4 at that time as the transmission signal. Send it back. That is, when the repeater 3 determines that a fire has occurred, for example, it returns not analog information but fire determination information. The receiver 1 only needs to identify the code of the returned determination information and generate a corresponding display or notification signal, and does not need to perform information determination processing. Further, since the repeater 3 immediately generates an appropriate output based on the determination result, a command from the receiver 1 is not required.

In a disaster prevention system consisting of a receiver that returns the received information, the repeater has means for receiving analog information from the disaster prevention sensor, and a means for discriminating the received analog information to prevent a fire,
comprising a judgment criterion means for converting into forecast judgment information, and an output means for generating an output such as an alarm output or a control output based on the judgment result of the judgment criterion means,
The relay called by the receiver sends back the information of the judgment result of the judgment standard means to the receiver.
Compared to sending analog information back to the receiver, the amount of information transmitted can be significantly reduced, and even if there are many disaster prevention sensors, the amount of information on the main line will not increase significantly.
This has the effect of significantly improving the system's information processing time and achieving the speedy processing required for a disaster prevention system.Furthermore, because the repeater performs judgment processing, the functions are distributed, which means that the risk of failure can be dispersed. The reliability of the system has been improved, and the distribution of functions has made it possible to simplify the configuration of each part, and it has also become possible to adjust the operation of each repeater, improving workability and making it easier to respond to increases and decreases in the system. be effective.
