The control unit 25 constantly monitors the output state of the fire detector M by communicating with the repeater 31 connected to the respective channels CH0 to CHl5 through the first to fourth muxes 21 to 24. .

The control section 25 and the first to fourth muxes 21 to 24 are connected in parallel as shown in FIG.

Accordingly, the controller 25 selectively drives the muxes 21 to 24 to operate by using the address (address) signal and the data (data) signal so that the input / output data is not disturbed so as to prevent the first to fourth operations. The data input from the repeater 31 connected to the respective channels CHO to CHl5 of the muxes 21 to 24 are correctly input.

The control unit 25 monitors the output state of the fire detector M with data input according to the control operation as described above, that is, data input from the plurality of repeaters 31, and as a result of the monitoring, the fire detector M If it is determined that the output state is changed, the output value is changed to the control means 1 via the serial input / output terminal PO.

The execution program stored in 253 is supplied through the RAM 255 to perform an output signal detection operation of the fire detector M.

As described above, the execution program may be supplied from the control means 1, but may be stored permanently in the second ROM 254 to reduce the program loading time.

On the other hand, the CPU 251 communicates with the first to fourth muxes 21 to 24 and various signals (Address, Data), and is connected to the channels CHO to CHl5 of the respective muxes 21 to 24. Monitor the output signal of the fire detector (M) installed in several places through the repeater (31).

That is, the first UART 212a outputs data input from the CPU 251 to the first level translator 214a, and the first level translator 214a outputs the input data to a signal level suitable for the RS232C communication standard. The first converter 215a converts and outputs the signal of the RS237C communication standard to allow the long distance communication to be output to the repeater 31.

The converter 215a converts the signal level of the input RS232C communication standard into a digital signal composed of 24V and OV and transmits the signal to the repeater 31.

The reason for amplifying the output signal as described above is that the signal level of the RS232C communication standard can be transmitted at a distance of about l00m to 200m, so that the driving means is far from the repeater 31 connected to the fire detector M. (2) and control means (1) to communicate with the repeater 31 without loss of data.

For reference, when the output signal is converted into a digital signal of 24V and OV and transmitted by the converter 215a, communication is possible without data loss even at a distance of 1 km.

In the present invention, 127 repeaters 31 are connected to one converter 215a.

That is, four muxes (four channels) are configured in one mux, and 127 repeaters 31 are connected to each of the transducers 215a to 215d. Thus, one mux communicates with 508 repeaters 31. I will.

On the other hand, when a response signal for data output from the first to fourth converters 215a to 215d is transmitted from the repeater 31, the first to fourth converters 2153 to 215d transmit the input response signal to RS232C. Converted to a signal level suitable for the communication standard and output to the first to fourth UARTs 212a to 212d through the first and second level converters 214a and 214b, and the UARTs 2123 to 212d respond to the input. The signal is output to the CPU 251.

In the above description, the first to fourth UARTs 212a to 212d transmit / receive data communicated between the CPU 251 and the repeater 31 according to the oscillation frequency supplied from the oscillator 213.

A level converter 313 for converting the signal level into a signal level, a converter 314 for amplifying the signal input from the level converter 313 for long-distance communication and transmitting it to the driving means 2, and four input terminals A first optical combiner (PCI) for reading the output signal of the fire detector (M) through the CPU 311 and supplying it to the CPU 311; The second optical coupler PC2 which detects the disconnection of four input terminals and supplies it to the CPU 311, the third optical coupler PC3 which performs the line test of the four input terminals, and the CPU 311. A voltage supply 315 for supplying or cutting off 24V power to the four-wire input terminal by switching operation under control, and a fourth optical coupler PC4 for outputting a fire detector (M) driving signal input from the CPU 311. ), And a relay switch 316 for operating the driving signal input from the fourth optical coupler PC4 to supply driving power of the fire detector M.

The operation of the repeater 31 configured as described above is as follows.

The CPU 311 constituting the repeater 31 receives data from the driving means 2 and performs an operation according to the input data.

That is, according to the data inputted from the driving means 2, there is a disconnection with the fire detector M, the line test, the output signal detection of the fire detector M, the operation of supplying the driving signal of the fire detector M, and the like. And the result is output to the control unit 25 of the drive means (2).

The CPU 311 turns on the voltage supply 315 to perform the operation so that a voltage of 24V is supplied to an input terminal of four wires.

As described above, when a voltage of 24V is supplied to the four-wire input terminal, the first optical combiner PCI reads the output signal of the fire detector M input through the four-wire input terminal and outputs the signal to the CPU 311. The second optical coupler PC2 detects the presence or absence of the disconnection of the four-wire input terminal and outputs it to the CPU 311. The third optical coupler P73 performs the line test of the four-wire input terminal.

The CPU 311 outputs a driving signal for supplying driving power to the fire detector M to the fourth optical coupler PC4, and the fourth optical coupler PC4 is a relay switch as an input driving signal. By operating 316, the driving power is supplied to the fire detector M. FIG.

As described above, when a series of operations are performed in accordance with the data input from the driving means 2, and the result of the operation is input from each of the optical couplers PCI to PC4, the CPU 311 performs the driving means (2). The control unit 25 outputs a response signal.

The response signal output from the CPU 311 is converted into a signal level suitable for the RS232C communication standard by the level converter 313 and output to the converter 314, and the converter 314 is output from the CPU 311. The response signal is amplified so as to be transmitted without loss of data even in a long distance and outputted to the first to fourth muxes 21 to 24 constituting the driving means 2.

At this time, the ID designator 312 designates the ID of the data output from the CPU 311.

The reason for assigning ID to the data output from the CPU 311 is 127 per channel for each of the channels CH0 to CHl5 formed in the first to fourth muxes 21 to 24 constituting the driving means 2. Since the repeaters 31 are provided, the control unit 25 of the drive means 2 which receives the data output from the repeater 31 by assigning a unique number, i. This is to make it easy to know whether the data is input from).

IDs assigned to each repeater 31 can be assigned to 128 IDs from 0 to 127, and 128 repeaters 31 connected to one channel are assigned different IDs.

In the ID, '0' is used as the common ID of all the repeaters 31, and thus, the ID of the repeater 31 is not used.

On the other hand, the driving means 2 and the repeater 31 applied to the present invention communicate data by serial data communication.

Serial data communication is performed by converting signal level to RS232C communication standard. 128 repeaters 31 are connected to one channel of the driving means 2 applied to the present invention, and the length of the communication line is about IKm. In order to prevent data loss even during long distance transmission, the level of transmitted data is amplified to digital data of 24V and 0V and transmitted. Figure 6 shows the structure of the transducer of the drive means (2) and the transducer of the repeater 31 for transmitting and receiving data through the transmission line in the present invention, electrically separating the transmission side and the transmission line And a transmission optical coupler PC5 for supplying transmission data to the transmission line by switching on / off by data to be transmitted, and transmitting data provided according to the switching operation of the transmission optical coupler PC5. Transistor 01 converts and transfers the signal level between the receiver side and the transmission line, and converts 24V and 0V data transmitted by the transistor 01 into an example bell of RS232C communication standard and supplies it to the receiver side. It consists of a receiving optical coupler PC6.

In addition, the above-described reference numerals Rl R2 and R3 are resistors, D is a light emitting diode, and Q is a transistor.

The transducer of the drive means 2 and the repeater 31 of the above-described structure operate as follows.

First, when data to be transmitted to the transmission optical coupler PC5 is input, the light emitting diode D constituting the transmission optical coupler PC5 emits light according to the input transmission data to form the transmission optical coupler PC5. The transistor Q is turned on / off switching.

As the transistor Q of the optical coupler PC5 for switching is switched, the transistor 01 connected to the transistor Q in Darlington is switched on and off to convert the level of transmission data to 24V and OV. It transmits to the receiving optical coupler PC6 through the transmission line.

The receiving optical coupler PC6 converts the transmission data having a level of 24V and 0V input through a transmission line into a signal level suitable for the RS232C communication protocol, and supplies it to the receiving side, thereby losing data during long distance transmission. The data is transmitted without it.

In addition, the diode D constituting the receiving optical coupler PC6 operates when 10 mA flows through the transmission line to convert the level of data transmitted through the transmission line to a signal level suitable for RS232C communication protocol. To lose.

As described above, when the diode D of the receiving optical coupler PC6 is operated in accordance with the current change of the transmission line, an error in data transmission does not occur even if the voltage of the transmission line changes due to external noise in the transmission line. There is no effect.

7 and 8 show the transmission data format between the drive means 2 and the repeater 31 applied to the present invention.

As shown in the figure, the driving means 2 and the repeater 31 applied to the present invention communicate in a data packet of 3 bytes or variable bytes.

The overall communication is started by the drive means 2 sending the command data to the repeater 31 and the end of the repeater 31 sending a response to the command to the drive means 2.

The command data transmitted from the drive means 2 to the repeater 31 is mainly 3 bytes. When the command for single operation is transmitted to the repeater 31, the command data of the variable byte is transmitted.

The command data transmitted from the drive means 2 to the repeater 31 is composed of an ID byte, a command byte, and a checksum byte, as shown in Fig. 7A. The ID byte is the first byte of the command packet. The most significant bit (MSB) is fixed to '1', and the ID number of the repeater 31 is input to the remaining 7 bits.

When the command data is to be transmitted to all the repeaters 31, the ID number is transmitted as '0'.

The command byte is the second byte of the command packet. The most significant bit is fixed as '0', and the command byte is inputted and transmitted to the remaining 7 bits to allow the relay 31 to perform various operations.

The checksum byte is the third byte of the command packet and is used to check an error of the command packet transmitted from the driving means 2 to the repeater 31.

The most significant bit of the checksum byte is fixed as '0', and the remaining 7 bits are inputted and transmitted by adding the 7 bits of ID byt7 and 7 bits of the command byte.

When the driving means 2 transmits the command packet as described above to the repeater 31, the repeater 31 checks the first byte of the input command packet, that is, the ID byte, and compares whether it is its ID.

If the result is the same as its ID, all remaining command bytes and checksum bytes are accepted.

The repeater 31 adds the input ID byte and the command byte and compares the data with the checksum byte.

As a result of the comparison, if the sum of the ID byte and the command byte is the same as the data of the checksum byte, the received command packet is received without error, and if not, an error occurs while the received command packet is being transmitted.

When the repeater 31 determines that an error has occurred in the received command packet as a result of the comparison, the relay 31 transmits a response signal indicating that an error has occurred to the driving means 2, and no error has occurred in the received command packet as a result of the comparison. If so, after performing a series of operations according to the command to transmit a response signal to the drive means (2).

On the other hand, the driving means 2 is the same as that of FIG. 7 which allows the repeater 31 to operate alone when communication between the repeater 31 and the driving means 2 is interrupted, in addition to the command packet of 3 bytes described above. The same rule table as b) may be transmitted to the corresponding relay 31.

The rule table is composed of an ID byte, a length byte, a rule byte, and a checksum byte.

The ID byte is the ID number of the repeater 31, the length byte indicates the number of rule bytes to be transmitted later, the rule byte is a command to operate the repeater 31 alone, the Checksum byte is an ID Enter the sum of byte, length byte, and rule byte.

The rule byte may transmit up to 127 bytes.

On the other hand, the repeater 31 transmits the result of the operation according to the command packet transmitted from the driving means 2 to the driving means 2 as described above, and the response signal is 3 bytes as shown in FIG. Send as response packet.

The response packet consists of an ID byte, a response byte, and a ChecKsum byte. The ID byte has the most significant bit fixed at '1', the ID number of the responding repeater 31 itself is input, and the response byte is input to the command packet. A response signal for the result of the operation or the occurrence of the error of the received command packet is input.

In addition, the checksum byte is transmitted by inputting a value obtained by adding the ID byte and the response byte, so that the driving means 2 having received the response packet can determine whether an error has occurred in the received response packet.

The repeater 31 performs an operation on whether or not an error occurs in the command packet received from the drive means 2, or a command of the command packet, and drives the result of the operation using a 3-byte response packet as described above. (2).

However, the repeater 31 does not respond to this case because all repeaters operate when the ID byte of the command packet input from the driving means 2 is '0'.

In the data format of the command packet and the response packet as described above, the drive means 2 and the repeater 31 communicate with each other, so that the output signal of the fire detector M, the connection state between the fire detector M and the repeater 31, and the like. It is transmitted to the drive means 2 through the repeater 31, the drive means 2 monitors the output signal of the fire detector (M) with a response packet input from the repeater 31, and the fire detector (M) and The repeater 31 will be able to detect whether or not the line short.
