The matrix circuits A to D respectively include these circuits 25
To 28 are interconnected. This matrix circuit A
To D, for example, the matrix circuit A 21 connected to the display device 16 illuminates a predetermined lamp, that is, a fire lamp in a fire-causing compartment, out of a large number of compartment lights based on a fire signal from the input reception processing circuit A 25. It is a circuit for making it. Also,
The input interface 14 is connected to each of these circuits 25
And the output interface 15 is connected to the input / output circuits 27 and 28 for the solenoid valve and the electric valve. Each of the matrix circuits A to D is formed of one substrate, and each of these circuits 25 to 28 is also formed of one substrate. The one substrate can control and monitor, for example, four sections of terminal equipment. In this conventional disaster prevention board, three boards are provided for each circuit, and 12 sections are controlled and monitored. In FIG. 7A, the electromagnetic valve input / output circuit 27 comprises a control circuit 41, a common relay 42, a valve opening relay 43, and a valve closing relay 44.
When the control valve 41 is opened, the control circuit 41 operates the common relay 42 and the valve opening relay 43, and when the solenoid valve 5 is closed, the control circuit 41 operates the common relay 42 and the valve closing relay 44. 7B, the motor-operated valve input / output circuit 28 includes a control circuit 51 having a polarity inversion circuit and two relays 52 and 53. When the motor-operated valve 6 is opened and closed, the control circuit 51 Activate relays 52 and 53,
The polarity is changed between the open state and the closed state by the polarity inversion circuit of the control circuit 51. Further, FIG. 8 shows a vacant line processing of the disaster prevention board. For example, when a vacant line to which the electromagnetic valve 5 is not connected occurs on the board of the electromagnetic valve input / output receiving circuit 27, the input / output circuit 27a and the disconnection monitor are connected as shown. A dummy resistor 55 is provided between the vacant terminals of the circuit 28a to prevent the disconnection signal from being output from the vacant line. [0006] The disaster prevention panel of the conventional tunnel disaster prevention equipment is constructed as described above, and the tunnel has a terminal such as the fire detector 2 to the motor-operated valve 6 as described above. Since there are many types of devices and the length of the tunnel itself is long, the number of devices is also large. For this reason, the number of circuit boards 21 to 28 increases, and the number of connection lines between the boards increases, resulting in erroneous connection and high cost.
There was a problem that the device itself became large. In addition, there are two types of automatic valves, one using an electromagnetic valve 5 and one using an electric valve 6. Since these control methods are different as described above, two types of substrates for the electromagnetic valve and the electric valve are used. This is necessary, and there is also a problem that the substrate cannot be shared and the production management in the factory is troublesome. Further, in the case where the terminal equipment, for example, the solenoid valve 5 which is one of the automatic valves is not installed on the board for the input / output receiving circuit, that is, in the case where the circuit becomes an idle line, the disconnection signal is not output. In order to do this, it is necessary to perform an empty line process of attaching a dummy resistor 55 between empty terminals. Also, after installing the terminal equipment in the tunnel,
The number of installations may be changed due to design change or design error. In this case, when reducing the number of terminal devices, it is necessary to perform the free line processing as described above.When increasing the number of terminal devices, remove the resistor if there is a free line on the board, and remove the resistor when there is no free space. Need to be increased,
There was a problem that it took time. The present invention has been made in order to solve such a problem, and the cost of the disaster prevention panel can be reduced by using a microprocessor to soften the configuration of the disaster prevention board.
Achieved miniaturization and shared the input / output circuit board for the solenoid valve and motorized valve, eliminating the need for free line processing, easily adapting to changes in specifications, and providing a disaster prevention panel with a high-speed disaster prevention panel. The purpose is to provide equipment. A tunnel disaster prevention facility according to the present invention includes a first storage unit for storing a disaster prevention processing program for various terminal devices, and a storage unit for storing various terminal devices for a predetermined section. A second storage unit that stores the number and types of terminal management data, and various types of data for a predetermined section based on the terminal management data stored in the second storage unit according to the disaster prevention processing program stored in the first storage unit. A plurality of section management boards including a first control unit for controlling and monitoring the terminal device, a board number setting switch provided for each management board and set with a unique number corresponding to each predetermined section; A third storage unit that stores the management program and terminal management data of the number and types of various terminal devices for each predetermined partition in the plurality of partition management boards, and a general management program stored in the third storage unit. A second control unit for transmitting terminal management data for various terminal devices for a predetermined section stored in the third storage unit to the section management board at the time of initial setting or power-on according to the system. The first control unit reads the unique number of the setting switch, and stores the management data corresponding to the unique number in the transmitted terminal management data in the second.
Is controlled to be stored in the storage unit. According to the present invention, the disaster prevention control of the tunnel is the first.
The partition management boards having the control units are distributed and arranged for each predetermined section, and various terminal devices are controlled and monitored, and the first control unit of each partition management board is totally managed and controlled by the second control unit. Therefore, it is inexpensive and has a high processing speed. When a plurality of partition management boards control and monitor various terminal devices for a predetermined partition, respectively, the second control unit performs initialization or power supply control according to the general management program stored in the third storage unit. At the time of start-up, the number of terminal devices and the type of terminal management data for each predetermined partition in the plurality of partition management boards stored in the third storage unit are sent out. After reading the number, the terminal management data for various terminal devices for a predetermined section corresponding to the unique number of the board number setting switch is received, and stored in the second storage unit of each section management board. In each partition management board, the first control unit according to the disaster prevention processing program stored in the first storage unit transmits various types of terminals for a predetermined partition based on the terminal management data stored in the second storage unit. Since the equipment is controlled and monitored, the contents of the terminal management data in the second storage unit must be changed when the number of terminal devices to be installed in a predetermined area assigned to the area management board is changed due to a design change or the like. And can be easily changed. In addition, even if the number of terminal devices is reduced, each partition
Since the control unit ignores the signal from the vacant line, it is no longer necessary to perform the vacant line processing of attaching a dummy resistor, which was conventionally required. FIG. 1 is a block diagram showing an embodiment of the present invention.
FIG. 2 is a diagram showing terminal management data of a terminal device in each partition management board stored in the ROM 1 of the embodiment, and FIG. 3 is a diagram showing data of the entire tunnel stored in the ROM 1 of the embodiment. And a comparison table for determining which section of the tunnel the section to be controlled and monitored by the section management base actually corresponds to. In the figure, reference numeral 100 denotes a disaster prevention board, and 101 denotes an MPU which is a second control unit of the disaster prevention board 100.
Reference numerals 1 and 102 denote a ROM 1 serving as a third storage unit in which the central management program and the number and types of terminal management data of various terminal devices for each predetermined partition in the plurality of partition management boards are stored. This ROM1 102 contains FIG.
And terminal management data as shown in FIG. 103 is a RAM 1 of a work area; 104 is a display device for displaying the status of the disaster prevention terminal device; 105 is a sound device having a buzzer and a bell for notifying a fire or a failure; 106 is a printer for printing the fire status; 107 is ventilation equipment 108, a signaling input / output circuit for outputting a drive signal for moving another facility, etc.
Is a numeric keypad for manual input in the case of water discharge and the like, and 109 is a test switch. 110 to 115 are display devices 104
To the test switch 109 interface. Reference numeral 120 denotes a partition management board for controlling and monitoring various terminal devices for a predetermined partition. Each partition management board 120 has an MPU2 121 as a first control unit mounted thereon. The MPU2 121 has a ROM2 122 as a first storage unit and a RAM2 as a second storage unit.
123 is built-in. The ROM2 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 an electromagnetic valve 5 and an electric valve 6, a disconnection monitoring program, and other specific programs. The processing method and the like are stored. Also, RAM 21
Reference numeral 23 is also used as a working memory for temporarily storing data in addition to storing terminal management data. 12
Reference numeral 4 denotes a board number setting switch including, for example, a dip switch or the like in which a unique number corresponding to a different predetermined section is set in each section management board provided on the section management board 120. Various terminal devices such as a fire detector 2, a manual alarm 3 and a fire hydrant 4 are connected to the MPU 2 121 via an I / F and automatically connected via a connector 125 and an automatic valve input / output circuit 126. Various terminal devices such as a valve 7 and a pressure switch 8 are connected. By connecting the automatic valve input / output circuit 126 to the connector 125 in this manner,
It can be installed and removed at any time.
This is because the automatic valve may not be installed depending on the property. 127 is MPU1 101 and MPU2
It is a transmission / reception circuit for exchanging signals with 121. It should be noted that the section management board 120 of this embodiment can control a terminal device for a predetermined section by one sheet. For example, a fire detector can control 10 sections. 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 the MPU1 101 will be described. MPU
In response to the input of various signals from the section management board 120, for example, a fire signal, based on the general management program stored in the ROM 1 102, the reference numeral 101 judges where the fire has occurred based on the signal. It performs control related to alarms such as emission of a predetermined section light (display element) and sounding of the acoustic device 105, and control of input / output devices such as the numeric keypad 108 and the printer 106. At this time, if, for example, a comparison table (for example, a section lamp to be lit and a section lamp to be lit) or a program that plays a role similar to that of the conventional matrix circuit is stored in the ROM 1102, the matrix circuit becomes unnecessary and connection lines are not required. Can be reduced. When each section management board 120 controls and monitors various terminal devices for a predetermined section, MP
It is necessary for the U1 101 to send the number and types of terminal management data of various terminal devices for each predetermined section in the plurality of section management boards stored in the ROM1 102 to the RAM2 123 of each section management board 120. The operation in which the MPU 1 101 sends the terminal management data stored in the ROM 1 102 to the RAM 2 123 of each partition management board 120 will be described with reference to the flowchart of FIG. First, initial setting is performed on the MPU1 101 (S2). Next, terminal management data is read from the ROM1 102 by the MPU1101 and transmitted to the partition management board 120 via the transmission / reception circuit 127 (S3). At this time, the MPU2 121 reads its own board number from the board number setting switch 124 of the section management board 120 (S4), and receives only the terminal management data corresponding to the board number from the terminal management data transmitted from the MPU1 101. Then, the response signal is stored in the RAM2 123, and a response signal is returned to the MPU1 101 (S5). And
The MPU1 101 determines whether all the MPU2 121 have received the terminal management data (S6). If it is determined that all the MPU2 121 have received the terminal management data, the MPU1 enters a terminal monitoring state (S7). . Otherwise, return 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 unit is the ROM21 which is the first storage unit.
In accordance with the disaster prevention processing program stored in the storage 22, various terminal devices in a predetermined section are controlled and monitored based on the terminal management data stored in the RAM 2 123 as the second storage unit. Therefore, when the number of terminal devices to be installed in a predetermined section handled by the section management board 120 is changed due to a design change or the like, the ROM 1 serving as 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 as the first control unit in each partition management board 120 ignores a disconnection signal from an empty line. You no longer need to. Further, the disconnection monitoring operation according to the embodiment of the present invention will be described with reference to the flowchart of FIG. First, MP
The U2 121 starts a 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 MPU 21 1 is checked.
21 first reads the signal state from the first n sections (S
12) It is checked whether there is a signal from the corresponding n sections (S13). Then, if there is the signal, it is read from the RAM2 123 whether or not the n section is used (S1).
4). This can be read because the corresponding terminal management data is sent from the ROM 1102 to the partition management board 120 and stored in the RAM 2123. This is because, for example, the fire detector may not be connected to the last two of the 10 sections that can be controlled and monitored by the section management board 120. In this case, the RAM 2
123 indicates the type of the terminal device connected to the 1st to 8th sections, and the MP that the terminal is not connected to the 9th and 10th sections.
The terminal management data sent from U1 101 is stored. This indicates that the MPU2 121 does not use the last two sections. If the n partitions are in use (S1)
5) It is checked whether or not the signal is a disconnection signal from a disconnection monitoring circuit in an n section (not shown) (S16). If the n sections are not in use, the section is an unused section, so the signal is ignored and the process proceeds to the next section. If there is a disconnection signal, it is displayed based on the disconnection signal or a buzzer sounds (S17). If the input signal is not a disconnection signal,
Corresponding processing such as outputting the detected fire signal to the MPU1 101 is performed (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 after checking a predetermined number of N sections (here, 10), the signal returns to the first section and reads signals. (S1
9, S20). As described above, in this embodiment, in the disconnection monitoring, it is possible to distinguish between the used section where the terminal equipment is provided and the unused section where the terminal equipment is not provided. It is more efficient than the case where Next, MPU1 101 and MPU2 12
The role of 1 and the interlocking control will be described. MPU2 1
When a signal from a terminal device, for example, a fire signal is received, the signal 21 is discriminated by a predetermined program, and is transmitted to the MPU 1 101 when it is determined that the signal is a fire signal. Upon receiving this signal, the MPU 1 101 operates the display and sound devices 104 and 105 to perform an alarm operation and, based on the fire signal and the number of fire occurrence zones, etc., determine which zone to release. Or which ventilator to operate. Then, a water discharge signal is transmitted to the MPU2 121 of the section management board 120 which controls the automatic valve 7 in the water discharge section. Upon receiving this release signal, the MPU2 121 sends a water discharge signal to the corresponding automatic valve 7. In the case where a fire occurs in the vicinity of the boundary section controlled and monitored by the continuous section management boards 120, for example, the 10th section and the 11th section, the MPU 1 101 controls both the section management boards 120. The water discharge section is determined based on the fire signal sent from the, and the water discharge signal is transmitted to each or one of the section management boards 120. As described above, the MPU1 101 is an MPU for a terminal device mainly for exchanging signals with the terminal device, whereas the MPU2 121 is an MPU for an overall control such as an alarm-related operation and an interlocking control. is there. Here, when data of a certain section management board 120 is changed by a design change or the like, the RAM
By changing the contents of the ROM 123, the RAM2 12 of the partition management board can be used without changing the contents of the ROM 102.
In some cases, changing only the contents of 3 is sufficient. However, in this case, if the contents of the RAM 2 123 are changed without permission, the MP that controls the plurality of partition management boards 120 in an integrated manner is used.
U1 101 is hindered. That is, when the number of fire detectors is newly increased in the RAM2 123, the data of the fire detectors is not in the management data of the ROM1 102. Therefore, when the fire detector 2 sends out a fire signal, Interlocking control as to which automatic valve 7 to release from becomes impossible. For this reason, even if the design is slightly changed, the contents of the ROM 1102 are changed to cope with the change. In addition, it is possible to store the number and types of terminal devices for a predetermined section in the ROM2 122 of the section management board 120 in advance at the time of initial setting. Are numerous and each R
Since the contents of the 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 block management board 120 can be used in any property tunnel,
By simply changing the content of 1102, any property can be easily handled. Further, a rewritable EEPROM may be used as the ROM1 102. As described above, according to the present invention, in the disaster prevention control of the tunnel, the partition management boards having the first control unit are distributed and arranged for every predetermined section, and various terminal devices are controlled and monitored. Since the first control section of the section management board is controlled by the second control section, the present invention has an effect of being inexpensive and having a high processing speed. When a plurality of partition management boards control and monitor various terminal devices for a predetermined partition, respectively, the second control unit operates according to the general management program stored in the third storage unit at the time of initial setting or power supply. At the time of start-up, the number of terminal devices and the type of terminal management data for each predetermined partition in the plurality of partition management boards stored in the third storage unit are sent out. After reading the number, terminal management data for various terminal devices for a predetermined section corresponding to the unique number of the board number setting switch is received and stored in the second storage unit of each section management board. In each partition management board, the first control unit according to the disaster prevention processing program stored in the first storage unit transmits various types of data for a predetermined partition based on the terminal management data stored in the second storage unit. Since the terminal devices are controlled and monitored, the contents of the terminal management data in the third storage unit are changed when the number of terminal devices to be installed in a predetermined block assigned by the partition management board is changed due to a design change or the like. Therefore, there is an effect that the change is easy. In addition, even if the number of terminal devices is reduced, the first control unit of each section management board ignores signals from the empty line, so that the empty line processing of attaching a dummy resistor, which is conventionally required, is performed. This eliminates the necessity, and the partition management board has an effect that it can cope with a case where the number of terminal devices is increased by providing an unused line in advance without using all lines at the time of initial setting. Further, in each partition management board, the first control unit is in accordance with the disaster prevention processing program stored in the first storage unit, and is sent various terminal devices for a predetermined partition stored in the second storage unit. Is controlled and monitored, so that the disaster prevention panel can be downsized. The two control methods of the solenoid valve and the motor-operated valve are stored in the second storage unit in advance. By using a circuit that combines the input / output circuit of a conventional solenoid valve and the input / output circuit of a motor-operated valve, that is, a circuit that has a common relay, two relays for opening and closing, and a polarity reversing circuit. Is also good. In this way, the first control unit determines whether the solenoid valve or the motor-operated valve is being used from the data in the second storage unit, and the first control unit controls the relay accordingly. By doing so, the conventional control circuit becomes unnecessary, the substrate of the input / output circuit of the automatic valve can be shared, and there is an effect that the production management becomes easy.
