DISCLOSURE OF THE INVENTION The conventional disaster prevention board of the tunnel disaster prevention equipment is constructed as described above, and the tunnel has the types of terminal equipment such as the fire detector 2 to the electric valve 6 as described above. Since there are many tunnels and the tunnel itself is long, the number of tunnels also increases. Therefore, the number of circuit boards 21 to 28 is increased and the number of connecting lines between the boards is increased, resulting in erroneous connection, high cost, and the disaster prevention board 10.
There was a problem that the size itself became large. Also, there are two types of automatic valves, one using the solenoid valve 5 and one using the motorized valve 6. Since these control methods are different as described above, there are two types of substrates for the solenoid valve and the motorized valve. It is necessary, the substrates cannot be shared, and there is a problem that manufacturing control in the factory is troublesome.

Further, when the terminal device, for example, the solenoid valve 5 which is one of the automatic valves, is not installed on the substrate for the input / output receiving circuit, that is, when it becomes an empty line, do not output a disconnection signal. In order to do so, it has been necessary to perform a vacant line process of attaching a dummy resistor 55 between vacant terminals. Also, after installing the terminal equipment in the tunnel,
The number of installations may change due to design changes or design errors. In this case, when reducing the number of terminal equipment, it is necessary to process the empty line as described above, and when increasing the number of terminal equipment, remove the resistor when there is an empty line on the board, and when there is no empty board Need to increase,

The MPU2 121, which is the first control unit, is mounted on each partition management board 120. The MPU2 121 includes a ROM2 122 that is a first storage unit and a RAM2 that is a second storage unit.
It has 123 built-in. The ROM 2 122 includes a disaster prevention processing program for processing signals from a plurality of terminal devices such as a fire detector 2, an automatic valve 7 including a solenoid valve 5 and an electric valve 6, a disconnection monitoring program, and other specific programs.

Various terminal devices such as the valve 7 and the pressure switch 8 are connected. By connecting the automatic valve input / output circuit 126 to the connector 125 in this manner,
It can be attached and removed at any time.
This is because some properties do not have an automatic valve. 127 is MPU1 101 and MPU2
A transmission / reception circuit for exchanging signals with the 121. It should be noted that the partition management board 120 of this embodiment can control the terminal devices for a predetermined partition by one sheet, and, for example, a fire detector can control 10 partitions. The disconnection monitoring circuit for monitoring the disconnection is not shown. Also, MPU1
101, ROM1 102, RAM1 103, and interfaces 110 to 115 are provided on a board different from the partition management board 120.

Next, the operation of the above embodiment will be described. First, the operation of MPU1 101 will be described. MPU
1 101 determines, based on the general management program stored in the ROM 1 102, various signals from the partition management board 120, for example, a fire signal, and from which signal the fire has occurred, and the display device 104 It controls alarms such as lighting a predetermined compartment lamp (display element) and sounding of the audio device 105, and controls input / output-related devices such as the ten-key pad 108 and the printer 106. At this time, for example, if the ROM 1102 stores a comparison table (for example, a fire occurrence section and a section lamp to be turned on) that plays a role similar to that of a conventional matrix circuit or a program, the matrix circuit becomes unnecessary and the connecting line is Can be reduced. When each partition management board 120 controls and monitors various terminal devices for a predetermined partition, MP
U1 101 needs to send the terminal management data of the number and type of various terminal devices for each predetermined partition in the plurality of partition management boards stored in the ROM1 102 to the RAM2 123 of each partition management board 120.

The operation in which the MPU1 101 sends the terminal management data stored in the ROM1 102 to the RAM2 123 of each partition management board 120 will be described with reference to the flowchart of FIG. First, the MPU1 101 is initialized (S2), then the MPU 1101 reads the terminal management data from the ROM1 102 and transmits it to the partition management board 120 via the transmission / reception circuit 127 (S3). At this time, the MPU2 121 reads its own board NO from the board NO setting switch 124 of the partition management board 120 (S4), and receives only the terminal management data corresponding to the board NO among the terminal management data transmitted from the MPU1 101. Then, it is stored in the RAM2 123 and the response signal is returned to the MPU1 101 (S5). And
In the MPU1 101, it is judged whether all the MPU2 121 have received the terminal management data (S6), and if it is judged that all the MPU2 121 have received the terminal management data (S7). . If not, the process returns to step S5. In this way, the terminal management data is stored in the RAM2 123 of all the partition management boards 120.

In each partition management board 120 in which the terminal management data is stored in the RAM2 123, the MPU2 121 which is the first control section thereof is the ROM2 1 which is the first storage section.
According to the disaster prevention processing program stored in 22, the various terminal devices for a predetermined section are controlled and monitored based on the terminal management data stored in the RAM 2 123 which is the second storage unit. Therefore, when changing the number of terminal devices installed in a predetermined section for which the section management board 120 is in charge due to a design change or the like, the ROM 1 which is the third storage unit is changed.
This can be dealt with by changing the content of the terminal management data stored in 102, and the change is easy. Also,
Even if the number of terminal devices is reduced, the MPU2 121, which is the first control unit of each partition management board 120, ignores the disconnection signal from the empty line. I no longer need to.

Further, the disconnection monitoring operation of the embodiment of the present invention will be described with reference to the flowchart of FIG. First, MP
The U2 121 activates the disconnection monitoring program, which is one of the disaster prevention processing programs stored in the ROM2 122 (S10). Next, the partitions managed by the MPU 2121 are sequentially checked (S11), and the MPU2 1
21 first reads the signal state from the first n sections (S
12) It is checked whether or not there is a signal from the corresponding n section (S13). Then, if there is such a signal, it is read from the RAM2 123 whether or not n partitions are used (S1).
4). This can be read because the terminal management data corresponding thereto is sent from the ROM 1102 to the partition management board 120 and stored in the RAM 2123. For example, the fire detector may not be connected to the last two compartments of the ten compartments that can be controlled and monitored by the compartment management board 120. In this case, the RAM 2 is used.
In 123, the type of terminal equipment connected to the 1st to 8th sections, and in the 9th and 10th sections, the terminal is not connected to the MP.
The terminal management data sent from U1 101 is stored. From this, it can be seen that the MPU2 121 does not use the last two partitions.

If the n partition is in use (S1
5) It is checked whether or not the signal is a disconnection signal from a disconnection monitoring circuit of n sections (not shown) (S16). If the n partition is not in use, the partition is an unused partition, so the signal is ignored and the process proceeds to the next partition. If there is a disconnection signal, the disconnection signal is displayed or a buzzer sounds based on the disconnection signal (S17). If the input signal is not a disconnection signal,
Corresponding processing such as outputting the detected fire signal to the MPU1 101 is carried out (S18), the process proceeds to the next section, and the same operation as described above is repeated. At this time, for example, the number of fire detectors assigned to the section management board is checked for each section, and when a predetermined number of N sections (here, 10) are checked, the signal is read back to the first section. (S1
9, S20).

As described above, in this embodiment, in the disconnection monitoring, it is possible to discriminate between the used section where the terminal device is provided and the unused section where the terminal device is not provided. Is more efficient than installing

Next, MPU1 101 and MPU2 12
The role of 1 and the interlocking control will be described. MPU2 1
21 receives a signal from a terminal device, for example, a fire signal, determines the signal by a predetermined program, and then sends the signal to the MPU1 101 if it determines that the signal is actually a fire signal. Upon receiving this signal, the MPU1 101 activates the display and the sound devices 104 and 105 to perform an alarm operation, and to determine which section should be emitted based on the fire signal and the number of sections of the fire occurrence. , Or which ventilator to operate. Then, a water discharge signal is sent to the MPU2 121 of the partition management board 120 which controls the automatic valve 7 in the water discharge section. Upon receiving this discharge signal, the MPU2 121 sends a water discharge signal to the corresponding automatic valve 7.

In addition, when a fire occurs in the periphery of the boundary section controlled and monitored by the continuous section management boards 120, for example, in the 10th and 11th sections, the MPU1 101 uses both of these section management boards 120. The water discharge section is determined based on the fire signal sent from, and the water discharge signal is sent to each or one of the section management boards 120. As described above, the MPU1 101 is an MPU for terminal equipment mainly for exchanging signals with the terminal equipment, whereas the MPU2 121 is an MPU for overall control such as alarm relation and interlocking control. is there. Here, when the data of a certain partition management board 120 is changed due to a design change or the like, the RAM
2123, the contents of the ROM1 102 can be changed without changing the contents of the ROM1 102.
It may be sufficient to change only the contents of item 3. However, in this case, if the contents of the RAM2 123 are arbitrarily changed, the MP that collectively controls the plurality of partition management boards 120
It interferes with U1 101.

In other words, when a new fire detector is added to the RAM2 123, the data of the fire detector is not in the management data of the ROM1 102. Therefore, when the fire detector 2 sends a fire signal, It becomes impossible to perform the interlocking control such as from which automatic valve 7 the valve is released. Therefore, even the slightest design change is made by changing the contents of the ROM 1102. In addition, it is possible to store the terminal management data of the number and type of terminal devices for a predetermined partition in the ROM 2 122 of the partition management board 120 in advance at the time of initial setting. In this case, the number of partition management boards 120 is set. There are many, and each R
Since the contents of OM2 122 are not always the same, it is very troublesome to adopt such a data input method. Therefore, according to the above-described embodiment, the same partition management board 120 can be used in the tunnel of any property, and the ROM can be used.
By changing the contents of 1102, you can easily deal with any property. Further, the ROM1 102 may use a rewritable EEPROM.

[0024]

As described above, according to the present invention, for disaster prevention control of a tunnel, partition management boards having a first control unit are distributed and arranged for each predetermined partition, and various terminal devices are controlled and monitored to manage each partition. Since the first control unit of the substrate is centrally managed and controlled by the second control unit, there is an advantage that the processing speed is low and the processing speed is high.

When the plurality of partition management boards respectively control and monitor various terminal devices for a predetermined partition, the second control unit follows initial control or power supply according to the general management program stored in the third storage unit. At start-up, terminal management data of the number and type of various terminal devices for each predetermined partition in the plurality of partition management boards stored in the third storage unit is sent out, and the first control unit sets the setting switch unique to the setting switch. , The terminal management data for various terminal devices for a predetermined section corresponding to the unique number of the board NO setting switch is received and stored in the second storage section of each section management board. , The first control unit of each partition management board follows the disaster prevention processing program stored in the first storage unit, and sends various data for a predetermined partition based on the terminal management data sent and stored in the second storage unit. Since the end devices are controlled and monitored, the contents of the terminal management data in the third storage unit are changed when the number of installed terminal devices in the predetermined partition handled by the partition management board is changed due to a design change or the like. This has the effect that it can be dealt with and the change is easy.

Further, even if the number of terminal devices is reduced, the first control unit in each partition management board ignores the signal from the empty line, so that the empty line processing, which is conventionally necessary, such as mounting a dummy resistor, is performed. There is an effect that it is not necessary, and if the partition management board does not use all the lines at the time of initial setting and an empty line is provided in advance, it is possible to cope with the case where the number of terminal devices is increased.

Further, in each partition management board, the first control section thereof is sent in accordance with the disaster prevention processing program stored in the first storage section and is sent to and stored in the second storage section. Since the software is used to control and monitor the disaster prevention panel, the disaster prevention panel can be downsized, and the two control methods of the solenoid valve and the motorized valve are stored in the second storage unit in advance. As for the circuit, the one that combines the input / output circuit of the conventional solenoid valve and the input / output circuit of the motorized valve together, that is, a common relay, two relays for opening and closing, and a polarity reversing circuit are used. Good. In this way, the first control unit determines which of the solenoid valve and the motorized valve is used from the data in the second storage unit, and the first control unit controls the relay correspondingly. By doing so, the conventional control circuit is not required, the substrate of the input / output circuit of the automatic valve can be shared, and there is an effect that manufacturing control becomes easy.
