Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a disaster prevention system equipped with intelligent repeaters.

[Background Art 1] Figure 8 shows the basic configuration of a conventional disaster prevention system of this type.
A plurality of repeaters 3 are connected via. Each repeater 3
A line 4 is connected to each line 4, and each line 4 is connected to a disaster prevention sensor 5 such as a smoke detector or a heat sensor that transmits an analog signal such as a current level or voltage level to a repeater 3 according to a sensing operation. is connected. The receiver 1 sends a transmission signal consisting of a pulse hood signal including an address signal individually assigned to each of the A-A units 3 via the main line 2,
When the address signal matches its own address, the repeater 3 takes in the above-mentioned transmission signal, converts the address signal from the disaster prevention sensor 5 connected to the line 4 into a pulse code signal, and sends it to the main line 2 as a transmission 4= signal. The data is sent back to the receiver 1 via the receiver 1. 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.

However, in such a conventional system, as the number of disaster prevention sensors 5 increases, most of the transmission is occupied by analog information transmission, which complicates the signal processing at the receiving (receiving) section 1 and significantly reduces the operational efficiency of the system. There was a problem.

OBJECT OF THE INVENTION 1 The present invention has been made in view of the above-mentioned problems, and its purpose is to improve the efficiency of information transmission on trunk lines, to disperse risks in the event of failure, and to achieve 1. The purpose of the present invention is to provide a disaster prevention system that can perform standard information processing on the receiver side.

[Disclosure of the Invention] FIG. 1 shows the circuit configuration of a receiver 1 and a repeater 3 used as an embodiment, and the repeater 3 has a criterion for discriminating analog signals from a disaster prevention sensor 5 connected to a line 4. A memory 6 such as a RAM for writing and storing data, and the memory 6
a determination unit 7 that determines the occurrence of a fire, a forecast, etc. by comparing the set standard data of the input analog signal with the input analog signal;
an output unit 8 that generates an output S such as a drive signal for an alarm bell or a control output for smoke prevention control based on the determination result of s7;
, a signal converter 9 that converts the determination result of the determiner 7 into a pulse code signal, and a signal converter 9 that determines whether the address matches when receiving the transmission signal and controls each unit, and returns the output of the signal converter 9 as a return signal. Signal processing unit 1 to send out as a signal
0, and normally receives power through the main line 2. The receiver 1 includes a storage section 12 that writes and stores judgment criterion data for each repeater 3 based on input data from an input section 11 such as a keyboard, and a storage section 12 that transmits transmission signals to the repeaters 3 and records data that has been transmitted. It is comprised of a signal processing liquid W and a section 13 that receives the returned signal and performs processing for determining the content. FIG. 2 shows the overall configuration of a disaster prevention system using the above-mentioned A-type relays 3, in which the receiving and transmitting signals 1 are transmission signals consisting of pulse code signals including address signals individually assigned to each repeater 3. is transmitted via the main line 2, and when the address signal matches its own address, the repeater 3 takes in the transmission signal, and at that time, the relay 3 receives judgment information based on the state of the disaster prevention sensor 5 connected to the fountain 4. is sent back as a transmission signal.

Next, the main operations of the present 'X embodiment will be explained based on the flowcharts shown in FIGS. 3 and 54.

Now, when a hard reset is performed at the receiver 1 by turning on the power or repeatedly operating the reset switch, the internal circuit of the receiver 1 is cleared, and each A-A unit 3 is sequentially called to perform an initial reset. After this, the receiver 1 determines whether the start switch SW for setting the initial start is turned on or not. If the start switch SW is turned on, the receiver 1 uses the storage section 1 The judgment standard data of each repeater 3 is read out and transferred to each repeater 3 in sequence, and if there is no input, the result is 2+! 'Start the system for processing.

On the other hand, when the repeater 3 receives a command from the receiver 1 side or receives an initial reset when the power is turned on, it initializes the internal circuits other than the memory 6, and then determines whether or not the judgment reference data has been transferred. , if there is a transfer, signal path J! Ij capital 10
The 1゛11 constant reference data transferred to the memory 6 is written under the control of the controller. Now, in the receiver 1, when the transfer of the judgment reference data is completed, it is stored in the memory 6 for each relay D3? l
Command to return the contents of the judgment criteria data that has been imported (i
send out the issue. When the intermediate heavy equipment 3 receives the return command, it returns the judgment standard data written in the memory 6. In the receiver 1, the returned judgment standard data and the previously transferred judgment standard data are compared in the signal processing calculation unit 13, and
Determine whether the judgment criterion data was correctly transmitted to the
After comparison, if they do not match, the determination reference data is retransmitted to the repeater 3 until it is correctly received. Then, when it is confirmed that the determination reference data has been correctly transferred to all repeaters 3, the system is started to perform regular processing. Further, in the repeater 3, when there is no longer a return command or the return is completed, the process shifts to normal processing. It is also recommended to repeat the above procedure when changing the judgment standard data.

FIG. . On the other hand, the receiving shore 1 is equipped with a writable memory 14 for writing judgment reference data for each repeater 3, and also a storage section 15 in which judgment reference data for control over between the repeaters 3 is written.

Next, the main operations of this embodiment will be explained with reference to charts 70 shown in FIGS. 6 and 7.

If a hard reset is applied by turning on the power or turning on the reset switch in the receiver 1, the internal circuit of the receiver 1 is cleared, and each repeater 3 is sequentially called to perform an initial reset. Thereafter, the stored contents of the memory are checked to determine whether or not the criterion data for each repeater 3 has been written, and if it has been written, the system is started to perform steady processing. In addition, if the data has not been written, a command signal is sent to each repeater 3 to return the judgment standard data written in the respective storage unit 6', and the returned judgment standard data of each repeater 3 is assigned to each one. The data is written to an area of the memory 14 that is . The repeater 3 performs an initial reset by a command from the receiver 1 or by turning on the power, clears the internal circuit, and then determines whether there is a return command from the receiver 1 side. The judgment standard data written in the storage unit 6° is returned, and if there is no judgment standard data, the process shifts to steady processing.

Note that when the system start step of chart 70 of each embodiment is completed, the process returns to RET.

[Effects of the Invention] As described above, the present invention provides a rewritable memory in the repeater, and writes the judgment criterion data set and transferred on the receiver side into this memory, so that the Either the fixed standard data or the storage section in which the judgment standard data of the judgment standard means is stored in advance is provided in the repeater, and the receiver calls the repeater and returns the judgment standard data stored in the storage section of the repeater. At the same time, since the returned judgment standard data is written to the writable memory provided in the receiver, the judgment standard data of the repeater can be centrally managed on the receiver side, and since the data source is in one place, there is no duplication. This makes it easy to change the judgment standard data without confusion, and by providing the judgment standard in the repeater, it is possible to reduce the judgment processing operation at the receiver and reduce the burden on the transmission system. This has the effect of increasing the efficiency of system operation.
