Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tunnel disaster prevention facility, and more particularly to a device for reducing the amount of wire rods in a transmission line connecting various terminal devices installed in a tunnel with a disaster prevention panel.

[0002]

2. Description of the Related Art Generally, in a disaster prevention facility of a tunnel, the tunnel is divided into a plurality of sections, and the plurality of sections are centrally monitored by one disaster prevention panel. Centralized type that controls the valve and extinguishes fire, and centralized monitoring with one disaster prevention panel when the tunnel becomes long is complicated because the configuration of the disaster prevention panel and the disaster prevention panel becomes large, so it consists of multiple sections in the tunnel There is a distributed type in which a relay board is provided for each monitoring range, and the relay board shares the same functions as the disaster prevention board. Further, the line system includes a P type in which a monitoring range is divided into a large number and a dedicated line is used for each divided section, and an R type in which a line common to a plurality of sections in each monitoring range is used. .

FIG. 3 is a schematic configuration diagram of a conventional centralized P-type tunnel disaster prevention facility. In the figure, 1 is a disaster prevention board that controls terminal devices such as a fire detector and an automatic valve, and 2 is provided in each section of a predetermined length along the longitudinal direction in the tunnel to automatically detect a fire. Fire detectors 3 are automatic valves provided for each section in the tunnel, and are opened / closed by a solenoid valve or a motor-operated valve (hereinafter referred to as a solenoid valve) 4 that is opened / closed by a control command from the disaster prevention panel 1 and a solenoid valve 4. And an open / close valve 5 that is opened. Reference numeral 6 is a water spray head as a plurality of water discharge heads provided in each compartment and supplied with water for extinguishing fire by the automatic valve 3. In addition, one automatic valve 3 is provided for each section divided every 50 m, and two fire detectors 2 are provided for each section divided every 50 m, for example.
In addition, although not shown in the figure, a manual transmitter that informs that a person who was driving by a car, for example, every four sections in the tunnel had a fire, a person who was passing by a car, etc. A fire hydrant containing a nozzle and a hose for extinguishing a fire is provided. Reference numeral 7 is a dedicated transmission line for separately connecting the disaster prevention panel 1 and the fire detector 2 for each section, and is for determining in which section a fire has occurred. 8
Like the transmission line 7, is a dedicated transmission line for separately connecting the disaster prevention panel 1 and the automatic valve 3 for each section. 9 is each on-off valve 5
It is a pipe for fire extinguishing water that supplies fire extinguishing water to.

The conventional tunnel disaster prevention equipment is constructed as described above. For example, when the fire detector 2 in a certain section of the tunnel detects a fire, the fire detector 2 fires through the dedicated transmission line 7. When a signal is sent to the disaster prevention board 1, and the fire prevention board 1 receives the fire signal, it activates a pump (not shown) to supply fire extinguishing water to the fire extinguishing water pipe 9 and to release a section from the fire occurrence section. The automatic valve opening signal is sent through the transmission line 8 connected to the electromagnetic valve 4 of the automatic valve 3 installed in the section to be discharged, and the electromagnetic valve 4 is opened and the on-off valve 5 is opened. That is, the automatic valve 3 is opened to discharge the water supplied from the water spray head 6 through the fire extinguishing water pipe 9. Further, when the total length of the tunnel is long, there is a large amount of information for controlling and monitoring various terminal devices such as the fire detector 2, so that it is difficult to control and monitor all the terminal devices in the tunnel with one disaster prevention panel 1. . Therefore, generally, a relay board that is almost the same as the disaster prevention board 1 or has a partial function of the disaster prevention board 1 is provided for each monitoring range consisting of a plurality of sections in the tunnel, and the disaster prevention board 1 centrally monitors these relay boards. The relay board controls and monitors various terminal devices to facilitate information processing functions.

[0005]

In the conventional tunnel disaster prevention equipment as described above, the disaster prevention panel 1 and the fire detector 2 for each section are used to determine in which section the fire has occurred. Dedicated transmission line 7 provided separately for each section
In addition, since the disaster prevention panel 1 and the automatic valve 3 for each section are connected by a dedicated transmission line 8 so that the section to which water is to be discharged can be specified, each section is connected. Since the transmission lines 7 and 8 are provided separately, the number of transmission lines increases and the overall cable length increases, which increases the cost of the transmission line wire and the related construction cost. There was a problem that misconnection was likely to occur. In addition to the fire detectors and automatic valves, there are various terminal devices to be controlled and monitored in the tunnel as described above. Not only that, but the tunnel itself is long, so even if a relay board is installed, And terminal equipment one to one
When connected by, the amount of wire materials such as transmission lines becomes enormous.
Moreover, there is a problem in that the space for installing these wire rods provided under the side road of the tunnel is limited, and if the number of wires increases, the structure of the tunnel itself must be improved.

The present invention has been made to solve the above problems, and by devising a connection method between a disaster prevention board and various terminal equipments, or a relay board and various terminal equipments, the amount of wire materials such as transmission lines can be reduced. The aim is to obtain disaster prevention equipment for tunnels that can reduce

【Example】

Example 1. FIG. 1 is a schematic configuration diagram of a first embodiment of the present invention. In the figure, the same components as those of the conventional example are designated by the same reference numerals, and the description of the components is omitted. This embodiment shows a disaster prevention facility for a short tunnel that does not require a relay board, 10 is a fire detector with an address having a different unique address, 11 is connected to a solenoid valve 4 of an automatic valve 3, and a unique A repeater having an address. In addition, this repeater 11
Is a DIP switch for setting its own address, a transmission / reception unit for receiving command information including an address transmitted via a transmission line, and transmitting status information of the automatic valve 3, and the address thereof. Is provided with at least a discriminating unit for discriminating whether or not the address matches the self-address. The disaster prevention board 1 and the fire detectors 10 with a plurality of addresses are connected in parallel by a first common transmission line 12. Further, the disaster prevention board 1 and the plurality of repeaters 11 are connected in parallel by a second common transmission line 13.

Next, the operation of the above embodiment will be described with reference to FIG. When the address-attached fire detector 10 detects a fire in a section in a short tunnel, the address-attached fire detector 10 sends out an address-attached fire signal via the first common transmission line 12, and the disaster prevention board In No. 1, when the fire signal is received, a pump (not shown) is activated to supply the fire extinguishing water to the fire extinguishing water pipe 9 and to determine the section to be discharged from the address of the fire signal, and the second transmission line 13 is set. The automatic valve opening signal which is the valve control command which added the address to the repeater 11 corresponding to the automatic valve 3 installed in the section where the water is to be discharged is sent via. Repeater 11
Then, when an address matching the self-address is detected for the valve control command including the address from the disaster prevention board 1, the valve control command is output to the solenoid valve 4 of the automatic valve 3. When the solenoid valve 4 receives the valve control command, it opens and the on-off valve 5 opens.
That is, the automatic valve 3 is opened to discharge the water supplied from the water spray head 6 through the fire extinguishing water pipe 9.

In the case of such a short tunnel, a repeater 11 is connected to each solenoid valve 4 of each automatic valve 3 for controlling water discharge to a plurality of water spray heads 6 provided for each section in the tunnel. Since the disaster prevention board 1 and a plurality of repeaters 11 are connected in parallel by a common transmission line 13, each section is provided between the disaster prevention board 1 and the automatic valve 3 or the fire detector 2 as in the conventional case. As compared with the case where the dedicated transmission line 7 is provided, the number of transmission lines and the length of the wire material can be reduced, the installation space can be easily secured, and the wire material cost of the transmission wire and the construction cost related thereto can be reduced. Also, since the number of transmission lines is small, it is possible to prevent erroneous connection.

Example 2. FIG. 2 is a schematic configuration diagram of the second embodiment of the present invention. In the figure, the same components as those of the conventional example are designated by the same reference numerals, and the description of the components is omitted. This embodiment shows a disaster prevention facility for a long tunnel requiring a relay board, and 14 is a relay board for controlling and monitoring the address-equipped fire detector 10 and the automatic valve 3 in each monitoring range consisting of a plurality of sections. The disaster prevention board 1 and each relay board 14 are connected to each other by separate dedicated transmission lines 15. Also,
The relay board 14 and the plurality of address-equipped fire detectors 10 in each monitoring range are connected in parallel by a first common transmission line 12. Further, the relay board 14 and the plurality of relays 11 in each monitoring range are connected in parallel by the second common transmission line 13.

Next, the operation of the above embodiment will be described with reference to FIG. When the address-attached fire detector 10 detects a fire in a section within one monitoring range in a long tunnel, the address-attached fire detector 10 is the first
A fire signal with an address is sent to the relay board 14 within the monitoring range via the common transmission line 12 of the relay board 14
Then, when the fire signal is received, the signal is sent to the disaster prevention board 1 through the dedicated transmission line 15. The disaster prevention board 1 activates a pump (not shown) to supply fire extinguishing water to the fire extinguishing water pipe 9, determines the section to be discharged from the address of the fire signal, and is installed in the section to be discharged. An automatic open signal is sent to the relay board 14 that controls and monitors the valve 3 via the transmission line 15. And the relay board 14 is the transmission line 1
3, an automatic valve opening signal, which is a valve control command with an address added, is sent to the relay 11 corresponding to the automatic valve 3, and the relay 11 responds to the valve control command including the address from the relay board 14. When an address matching the self-address is detected, the valve control command is output to the solenoid valve 4 of the automatic valve 3. Upon receipt of the valve control command, the solenoid valve 4 opens to open the on-off valve 5, that is, to open the automatic valve 3 to discharge the water supplied from the water spray head 6 through the fire-extinguishing water pipe 9.

In the above embodiment, when the fire detector 10 detects a fire, the fire signal is sent to the disaster prevention panel 1 or the relay panel 14, but the relay panel 14 and the fire detector 10 are connected to each other. Information such as fire and breakdown may be exchanged by constant polling. Similarly, various signals are exchanged between the relay board 14 and the disaster prevention board 1, and the relay board 14 is accompanied by a state information collection command from the disaster prevention board 1.
Sends the information such as the status information of the fire detector 10 collected earlier to the disaster prevention board 1. In this case, it is judged whether the disaster prevention panel 1 is a fire, not the fire detector 10.

In the case of such a long tunnel, a relay panel 14 for controlling and monitoring the fire detector 10 and the automatic valve 3 in each monitoring range consisting of a plurality of sections is provided, and the relay 11 is connected to each automatic valve 3. , The disaster prevention panel 1 and each relay panel 14 are respectively connected by separate dedicated transmission lines 15, and each relay panel 14 and a plurality of repeaters 11 in its monitoring range are connected in parallel by a common transmission line 13. Further, since each relay board 14 and the plurality of fire detectors 10 in its monitoring range are connected in parallel by the common transmission line 12, an automatic valve in the relay board and the monitoring range or a fire detector is used as in the conventional case. Compared to the case where a dedicated transmission line is installed between each section, the number of wire rods such as transmission line is smaller, and the installation space can be easily secured, and the wire rod cost of the transmission line and related construction costs are lower. It made.

The disaster prevention panel 1 and the relay panel 14 need not be connected to each other by a dedicated transmission line 15 on a one-to-one basis.
Multiple relay boards may be connected in parallel to one transmission line. However, in this case, if the transmission line is broken or short-circuited,
Most of the tunnel is damaged. On the other hand, in the case of 1: 1, there is an advantage that it is resistant to accidents such as disconnection and short circuit. Moreover, since the amount of information between the disaster prevention panel 1 and the relay panel 14 is much larger than that between the relay panel 14 and the terminal equipment, it is expensive to use a single transmission line to transmit that much information, such as a fiber material such as fiber. However, it is possible to use an inexpensive electric wire by making it 1: 1. Further, in the above embodiment, the fire detector with an address is used for description, but a fire detector without an address may be connected to the transmission line via a relay. Also, the first transmission line and the second transmission line are provided so that the fire detector and the repeater are connected separately, but of course, one fire detector and automatic valve are both connected to one transmission line. However, the number of wire rods can be further reduced by doing so.

[0018]

As described above, according to the present invention, in the case of a short tunnel, an automatic valve for controlling water discharge to a plurality of water spray heads provided for each section in the tunnel includes an address from a disaster prevention board. When an address that matches the self-address for a valve control command is detected, a repeater that outputs the valve control command to the automatic valve is connected, and the disaster prevention board and multiple repeaters are connected in parallel with a common transmission line. Since it is configured as described above, the number of wire rods such as transmission lines can be reduced compared to the case where a dedicated transmission line was provided for each section between the disaster prevention panel and the automatic valve or fire detector as in the past. This has an effect that a space can be easily secured, a wire rod cost of the transmission line and a construction cost related thereto are reduced, and an erroneous connection can be prevented.

Further, in the case of a long tunnel, a relay panel for controlling and monitoring the fire detector and the automatic valve in each monitoring range consisting of a plurality of sections is provided, and each automatic valve is provided with a relay panel or a relay panel from the disaster prevention panel. The relays that output the valve control command to the automatic valve when an address that matches the self-address is detected for the valve control command including the specified address are connected respectively, and the disaster prevention panel and each relay panel transmit their own signals. Since each relay panel and multiple relays and fire detectors in its monitoring range are connected in parallel by a common transmission line, each relay panel and fire detector are connected in parallel. Compared to the case where a dedicated transmission line is installed between the valve and the fire detector for each section, the number of wire rods such as transmission line can be reduced, the installation space can be easily secured, and the transmission line wire cost and The cost of the construction is cheaper involved in, has an effect that an erroneous connection can be prevented.
