Abstract

PURPOSE:To sprinkle water to a tunnel, for which a fire generation confirming signal is outputted, when the water is not sprinkled in any tunnel by providing a second water discharge control means to send the clear signal of under-water discharge information from a second storing means in an automatic master water discharge controller when a fire extinguishment confirming signal is received. CONSTITUTION:A water discharge demanding signal is sent from an automatic slave water discharge controller 15. Then, when the water is not sprinkled to any tunnels Tu1, Tu2...TuN, a water discharge permitting signal is sent from an automatic master water discharge controller 10 to the automatic slave water discharge controller 15 which sends the water discharge demanding signal. Then, only when there is not tunnel, to which the water is already sprinkled, the water can be sprinkled. Thus, the water is not simultaneously sprinkled from a water tank to two water discharge blocks and the information of the automatic slave water discharge controller 15 are collected to the automatic master water discharge controller 10. Then, a control state by each automatic water discharge controller is totally controlled by the automatic master water discharge controller.

The interior of the tunnel TLII is divided along its length into fire warning sections - "A + , B t , Ct '-", and each fire warning section is provided with one or more fire detectors FD. In addition, along the length of the tunnel TLIl, there are water discharge sections corresponding to the fire warning sections...z,

The nozzle N2 of each water discharge section is opened and closed by a respective electromagnetic valve SO to control water discharge from the nozzle N2 and cutoff of water discharge.

Furthermore, the configuration is similar for the tunnel T''uz.In addition, -Az, B*, CZ, - are the fire warning sections of the tunnel Tut, -W, ,X,,Y,

The automatic water spray control device 100 of this embodiment is configured by a microcomputer, and the automatic water spray control device 200 is also the same. Further, as shown in FIG. 3, the automatic water spray control device 300, -NOO, which is not shown in FIG. 2, is also the same, so the automatic water spray control device 100 will be explained. As will be described later, among a plurality of automatic water spray control devices, the automatic water spray control device lOO will be described as a master automatic water spray control device, and the other automatic water spray control devices 200, 300, . . . - will be described as slave automatic water spray control devices. Below, master automatic water discharge control device 1
When it is necessary to distinguish between 00 and the slave automatic water discharge control device 200, the words master and slave will be added. Also, the symbols for the fire warning compartment, fire detector, water discharge compartment, nozzle, solenoid valve, and water tank are omitted.

The automatic water discharge control device 100 includes a central processing unit (CPU) 10
1, a ROM 102, a RAM 103, an input interface circuit 104, and an input/output interface circuit 105.

The ROM 102 includes ROM 1 that stores programs, ROM 2 that stores information on whether or not a water tank is shared between the tunnel TUI and tunnel T'uz, and input/output bits that store the relationship between the fire warning section and the water discharge section. It consists of a ROM 3 stored as a pattern table. ROM

RAM 103 stores information that water is being discharged in the water discharge section of the own tunnel (a tunnel whose water discharge is controlled by the automatic water discharge control device concerned); RAM 20 stores the information that water is being discharged in the water discharge section of the tunnel); RAM 30 stores the fire detection output from the fire warning section; RAM 40 stores the fire detection output of the fire warning section currently being processed; RAM 50 that stores water discharge control data for determining whether water is discharged from the compartment.
, a RAM 60 that stores a water discharge standby code, and a RAM 70 that forms a work area. As in the case of the ROM 102, the RAMs 10 to 70 may be respective storage areas provided within the RAM 103.

Output from lock release switch 130, recovery confirmation switch 1
The outputs from 40 and master instruction switch 150 are supplied to central processing unit 101 via input interface circuit 104 .

The lock/unlock switch 130 is a switch that the operator instructs to discharge water after confirming a fire, and the recovery switch 1
40 is a switch that indicates that the fire has been extinguished, and a master instruction switch 150 is a switch that indicates that it is a master automatic water discharge control device. Furthermore, the output from the fire detectors forming each fire alert area is inputted via the input interface circuit 104. For example, the output terminals of the fire detectors in the fire warning section may be inputted in parallel, or the outputs of each fire detector may be input independently and the central processing unit 101 determines which fire alarm is being detected. It may be determined whether it corresponds to a partition. The input interface circuit 104 includes slave automatic water spray control devices 200 to 200.
A water discharge request signal is sent from the NOO requesting water discharge to water discharge sections within its own control range.

The central processing unit 101 also has a human output interface circuit 1.
05 to control the opening and closing of the nozzle through a drive circuit 106 that drives a solenoid valve for each water discharge section. Further, through the human output interface circuit 105, the tunnel T
'uz, etc., the water discharge enable signal indicating whether water discharge is permitted or not, the water discharge enable signal is the master automatic water discharge control device 100.
or is sent to the Q slave automatic water discharge control device 200-NOO.

Furthermore, a water spray signal indicating that water is being sprayed is sent from the slave automatic water spray control device 200-N00 to the master automatic water spray control device 100 via the input/output interface 105. Furthermore, the status of fire detection for the fire warning compartment and the status of water spraying for the water spraying compartment are displayed on the display device 107 via the input/output interface circuit 105.

When the master automatic water discharge control device 100 receives a water discharge request signal from the slave automatic water discharge control devices 200 to NOO, the master automatic water discharge control device 100 enables water discharge when water is not being discharged from the water tank TA to any one tunnel. In other words, when water is not being discharged in the tunnel for a slave automatic water discharge control device other than the slave automatic water discharge control device that has output the water discharge request signal, and in the water discharge section of the tunnel for the master automatic water discharge control device, the slave that has output the water discharge request signal A water discharge enable signal is sent to the automatic water discharge control device to enable water discharge in the corresponding tunnel, and conversely, water is discharged from water tank T.
When water is being sprayed onto a tunnel, a water spraying prohibition signal is sent to control the water spraying from that tunnel.

The operation of an embodiment of the present invention configured as described above can be explained using a ROM.
This will be explained with reference to FIGS. 4 to 6 along with the program stored in I.

After the start, initial settings are made, and if a recovery confirmation signal is not input, a check is made to see if a master instruction has been given by the master instruction switch 150, and if a master instruction has been made, processing routine (1) is executed. (steps a”-d).

The master instruction switch 150 is set to the ON state for the automatic water discharge control device 100, and a master instruction is being given, and step C is followed by step d.
is executed. In a state where the master instruction switch 150 is set to the OFF state and a slave instruction is given to the automatic water discharge control devices 200 to NOO, step d is skipped and step C is followed by step e described below. is executed.

When the processing routine (1) is executed, it is checked whether or not the water spray code is stored in the RAM 10 (step d).
If the water discharge code is not stored in 0, that is, if there is no discharge in the tunnel T'ut, step d1
Subsequently, for example, 10'' is placed in register B (step aX), and then the value placed in register B is set to TI +
111 (step d3), and the slave automatic water discharge control device (200, ---
1 or N00) is sending out a water discharge signal indicating that water is being discharged (step a). If it is determined that the water discharge signal has not been sent, it is checked whether the value n set in register B has reached the number of slave automatic water discharge control devices (N-1) (step aS).

When it is determined in step ds that the set value of B has not reached (N-1), step d is executed again to check whether a water discharge signal is being sent from any of the slave automatic water discharge control devices. checked (step d)
,~aS). When it is determined in step d4 that the water discharge signal is being sent out, the water discharge code is stored in the RAM 20 following step d4 (step d4).
t). When it is determined in step ds that the water discharge signal has not been sent from all the slave automatic water discharge control devices 200-NOO, the memory contents of the RAM 20 are cleared (step at).

The reason why the stored contents of the RAM 20 are cleared in step d is because even if water is discharged upon receiving the water discharge enable signal, the water discharge may be terminated upon confirmation of recovery.

Following step d, all slave automatic water discharge control device 20
Sending of the water discharge/non-discharge signal to 0 to NOO is stopped (step dII).

When it is determined in step d that the water spray code is stored in RAMl0, in step d6 R
When the water spray code is stored in AM20 or when the sending of the water spray no signal is stopped in step d8, '0'' is set in register B (step ti,
, ), then the value in register B is incremented by 1°11" (
Step d+o), slave automatic water spray control device (200, ..., or No. 0) corresponding to the register setting value
) is checking whether a water discharge request signal is being sent from (steps d, l). If it is determined that the water discharge request signal has not been sent, it is checked whether the value set in register B has reached the number of slave automatic water discharge control devices (Nl) (step d+z) - step dl! When it is determined that (n=N-1) is not the case, step d is performed again. is executed. Therefore, it is checked whether a water discharge request signal has been sent from any of the slave automatic water discharge control devices (steps dlO to d1□). Ste, Tsubu d1゜~dl! When it is determined that the water discharge request signal is not being sent from all slave automatic water discharge control devices, the processing routine (
Exiting from step 1), step e is executed following step d1□.

In step d, when a water discharge request signal is being sent from the B-th slave automatic water discharge control device, for example, tt Ott is set in register C (step d+s), and then the value set in register C is set to u. +1 ee
Then, it is checked whether the water spraying code is stored in the RAM 10 (step ct Is). When it is determined in step atS that the water spraying code is stored in RAMl0, following step atS, a water spraying prohibition signal is sent to the slave automatic water spraying control device corresponding to the set value B of register B in step d1°. A signal is sent (step d14)
. In step dl &, the water spraying refusal signal is sent to the slave automatic water spraying control device corresponding to the set value B of register B because the water spraying request signal is sent from the slave automatic water spraying control device corresponding to the set value B of register B. This is because water has already been discharged in the tunnel Tu under the control of the master automatic water discharge control device 100.

If the water spray code is not stored in RAM10 at step dls, then the RAM
A check is made to see if a water spray code is stored in 20 (step d+s). Step d1. When it is determined that the water spraying code is stored in the RAM 20, step dl& is executed following step dlll. When the water spraying code is stored in the RAM 20 in step dl11, the water spraying non-signal is sent to the slave automatic water spraying control device corresponding to the set value B of register B. This is because, although the water discharge request signal has been sent from the corresponding slave automatic water discharge control device, water has already been discharged into the tunnel by another slave automatic water discharge control device.

Following step d0, it is checked whether the water request signal is still being sent (step d, . . .).

If it is determined in step dll that the water spraying code is not stored in the RAM 20, a water spraying enable signal is sent to the slave automatic water spraying control device corresponding to the set value B of register B following step dll+ (step dI9).
). In steps d and Q, the water discharge enable signal is output to the slave automatic water discharge control device whose water discharge enable signal corresponds to the set value B of register B. This is because the water discharge request signal is output from the slave automatic water discharge control device corresponding to the set value B of register B. is being sent out, and water is not being discharged in the tunnel TL11 corresponding to the master automatic water discharge control device and the tunnel 'ruz-'run corresponding to the slave automatic water discharge control device. Following step d19, RAM20
The water discharge code is stored in (step d8°), and step d0 is executed following step ago.

Step dl? , it is checked whether the water discharge request signal is still continuing, and when it is determined that the water discharge request signal is continuing, it is checked whether the set value C of the register C matches the predetermined set value T. is checked (step d!+), step d! When it is determined that the value C set in the register C is less than the set value T in step d!
, step d14 is executed. Register C
When it is determined that the set value C of register B is equal to the set value T, the sending of the water discharge enable signal that was being sent to the slave automatic water spray control device corresponding to the set value B of register B is stopped (step dgt), and then Steps d and t are then executed. Therefore, step d,. , dll, and checks whether a water discharge request signal is being sent from the remaining slave automatic water discharge control devices following the slave automatic water discharge control device that had sent the water discharge request signal. Step d again! The reason for waiting for the set value T at step d19 is to regulate the sending period of the discharge permission signal sent out in step d19, and also to wait for the set value T or longer if the water discharge request signal continues to be sent due to a malfunction or other reason. This is to get you out of the loop. Note that the water spray no signal and the water spray enable signal output in steps dl&, dll are latched by the latch circuit corresponding to the slave automatic water spray control device that sent the water spray request signal in the input/output interface circuit 105, and the slave automatic water spray It will be referenced by the control device. As a result of reference, the control of tunnel water discharge by the slave automatic water discharge control device will be described later.

If it is designated as a master automatic water spraying control device, the process routine (1) is executed, and if it is not designated as a master automatic water spraying control device, that is, if it is specified as a slave automatic water spraying control device, it continues with step C. Then, it is checked whether or not water is being discharged in the own tunnel (step e), and if there is not water being discharged in the own tunnel, the stored contents of the RAM 20, that is, it is checked whether or not water is being discharged in other tunnels (step f).

In step f, if it is determined that water is not being sprayed in other tunnels, it is checked whether a signal from the lock piece switch 130 is being input (step g).
. In step g, it is checked whether the operator has confirmed that there is a fire.

When the signal from the lock piece switch 130 is input, following step g, the fire detection output from the fire alarm compartment is read and stored in the RAM 30 (step h);
The storage contents of the RAM 30 and the storage contents of the RAM 40 are compared (step i), and as a result of the comparison in step l,
It is checked whether there has been a change (step j).

However, since the fire detection output for each fire alarm section is stored in the RAM 30 in step h, and the fire detection output for each fire alarm section currently being processed is stored in the RAM 40, as a result of comparing the two, When there is a change, it means that a fire has occurred in a new fire warning division, and when there is no change, it means that there is no new fire warning division.

When a fire occurs in a new fire warning section, the contents of RAM 30 are stored in RAM 40 (step k). As a result, the latest fire detection ratio cover turn for the fire alert area is stored in the RAM 40. Next, it is checked whether or not a master instruction has been issued by the master instruction switch 150 (step l).
If no master instruction is given in step m, processing routine (II) is executed (step m). When a master instruction is given in step l, the processing routine (I
I) is skipped. That is, in the master automatic water spray control device 100, the processing routine (II) is not executed, but step n, which will be described later, is executed, and the slave automatic water spray control bag 22 is executed.
At 00-NOO, the processing routine (It) is executed.

When the processing routine (rl) is entered, a water discharge request signal is sent from the master automatic water discharge control device 100 Heslepe automatic water discharge control device (step m+). This is slave automatic 1
This is because a new fire warning area was detected in a tunnel controlled by a water discharge control device, and
We will be asking for permission to release water. Following step m1, u O'' is placed in register C (step m2), then +1'' is added to the value set in register C (step ma),
Step m4) reads out the water discharge permission/no signal sent from the master automatic water discharge control device 100 to the slave automatic water discharge control device that sent the water discharge request signal, and checks whether or not the water discharge permission signal is received (step m4). ms). When it is determined in step m that the water discharge permission signal is being sent, water is permitted to be discharged to the tunnel controlled by the slave automatic water discharge control device, and following step m, the water discharge permission signal is sent. The RAM 20 of the slave automatic water spray control device is cleared (step m)), and the processing routine (II) is exited. When it is determined in step m that the water spray enable signal is not being sent out, it is checked following step m whether or not the water spray no signal is being sent out (step m6). When it is determined in step m that a water discharge prohibition signal is being sent, it is a case where water discharge to the own tunnel is not permitted, and the water discharge indicating that water is being discharged from another tunnel is stored in the RAM 20 of the slave automatic water discharge control device. The middle code is stored (step m6), and the process exits from the processing routine (II). Here RA
The reason why the water discharge code is stored in M20 is because water is being discharged into a tunnel for other automatic water discharge control devices. When it is determined in step m6 that the water discharge/non-discharge signal is not sent out, following step m&, a check is made to see if the value set in register C is less than a predetermined set value T (step m .

Therefore, when there is neither a water discharge enable signal nor a water discharge prohibition signal, steps m and ~m are repeated for a period corresponding to the set value T, and the process exits from the processing routine (II), resulting in a loop of steps m and ~m. It will not reach a state where it cannot be removed. Furthermore, the readout of the water discharge permission/no signal is (
Step m4) is performed by reading the latch output of the latch circuit of the input/output interface circuit 105 of the master automatic water spraying control device 100.

If it is designated as a master automatic water discharge control device, following step 1, and if it is designated as a slave automatic water discharge control device, following the execution of processing routine (II), it is possible to confirm that water is being discharged in other tunnels. It is checked whether the indicated water discharge code is stored in the RAM 20 (step n). In step n, RAM2
If the water discharge code is stored in 0, that is, it is determined that water is being discharged in another tunnel, then the RAM
A water discharge standby code is stored in 60 (step p). The reason why the water discharge standby code is stored in the RAM 60 is to indicate that water cannot be discharged to the own tunnel because water is being discharged from another tunnel and is in a standby state.

When it is determined in step n that the water spray code is not stored in the RAM 20, the R
The input bit pattern of ROM 3 that matches the code stored in AM 30 is determined, and the output bit pattern of ROM 3 corresponding to the input bit pattern of ROM 3 that matches the code stored in RAM 30 is stored in RAM 50 (step q). . RAM following step q
50, a signal corresponding to the bit pattern of the memory is sent to the drive circuit 1.
The signal is output to each electromagnetic valve via 06 to drive the electromagnetic valve. This drive is performed by opening the solenoid valve corresponding to the bit position set to logic II II II in the bit pattern stored in the RAM 50, and from the nozzle of the water discharge section connected to the solenoid valve that has been opened. Water is sprayed (step, pump S).

Following step S, a water discharge code is stored in RAM10, and the fact that water is being discharged is stored in RAM10 (step t). The reason why the water spraying code is stored in the RAM 10 in step t is because water is being sprayed onto the own tunnel. Following step L, master instruction switch 15
It is checked whether a master instruction of 0 has been made (step U). When it is determined in step U that no master instruction has been given, that is, in the case of a slave automatic water spray control device, a water discharge raw signal is sent to the master automatic water discharge control device 100 following step U (step V), and then Sending of the water discharge request signal is stopped (step W). Following step W, the water discharge standby code stored in the RAM 60 is cleared (step X).

Further, when a master instruction is given to step U, step V and step W are skipped, and step X is executed following step U.

Also, when it is determined that there is no change in step j,
In other words, if there is no fire warning area where a new fire has occurred as a result of the comparison in step j, it is checked whether or not a water spray standby code is stored in the RAM 60, and if a water spray standby code is stored, step l is executed. is executed (step r). The reason for providing step r here is that there was a change in step i in the previous program execution, but the master automatic water discharge control device 100
If water cannot be discharged because a water discharge prohibition signal is output from the tunnel, and the water discharge standby code is stored in the RAM 60 in step p, and water discharge in the tunnel concerned is made to wait, the tunnel side that was discharging water is restored and the water discharge is stopped. This is to enable water to be discharged to the water discharge section of the tunnel.

If the water spray standby code is not stored in the RAM 60 in step r, if step p is executed, or if step X is executed, step b is executed again.

In addition, in the above-described embodiment of the present invention, the automatic water discharge control device 100 is the master automatic water discharge control device and the automatic water discharge control devices 200 to NOO are the slave automatic water discharge control devices. The master and slave instructions can be changed by setting the
Even if the instructions of the master automatic water discharge control device and the slave automatic water discharge control device are exchanged, the operation is the same as in the above embodiment.

Furthermore, in the embodiment of the present invention described above, the tunnel is divided into a plurality of parts and the tunnel TUI is designated as TLIN, but the tunnels T'ut and -"r'uN may be independent. (It is only necessary to share the aquarium TA.

Furthermore, in the above-described embodiment of the present invention, the master automatic water spray control device and the slave automatic water spray control device have the same configuration, so that the master or slave can be selected as desired. Conversely, the master automatic water discharge control device and the slave automatic water discharge control device may each be provided with necessary components.

(Effects of the Invention) As explained above, according to the present invention, the slave automatic water discharge control device sends a water discharge request signal, and when there is no tunnel under water discharge, the slave automatic water discharge control device that has sent the water discharge request signal By sending a water discharge enable signal to the automatic water discharge control device, water can be discharged only when there are no tunnels that are already being sprayed with water, so water will not be discharged from the tank to two water discharge sections at the same time.
In addition, since the information of the slave automatic water spray control devices is collected by the master automatic water spray control device, the control status of each automatic water spray control device can be managed collectively by the master automatic water spray control device.

Furthermore, there is no limit to the number of slave automatic water discharge control devices that are collectively managed.

Moreover, since there is no limit to the number of slave automatic water spray control devices, automatic water spray control devices, especially slave automatic water spray control devices, can be added later.

Furthermore, the number of signal transmission paths between the master automatic water spraying control device and the slave automatic water spraying control device is small.

Furthermore, by equipping the master automatic water spraying control device with the function of a slave automatic water spraying control device, it is possible to arbitrarily select between the master automatic water spraying control device and the slave automatic water spraying control device. In this case, all automatic water discharge control devices have the same configuration, and there is no need to differentiate them during manufacturing.
