管系の寿命が短くなるという問題があった。However, in such a conventional fire extinguishing system, a water supply pump having a different performance is used for each type of the fire extinguishing system, and a piping system of each fire extinguishing system is provided independently. Therefore, there is a problem that the mutual backup cannot be performed even when the feedwater pump fails. Further, there is a problem that the cost is high in terms of facilities and power consumption. On the other hand, conventional fire extinguishing equipment supplies water at a pressure that can secure the required pressure on the top floor, so if the pump is started at the time of fire or inspection, excess pressure will be applied to pipes other than the top floor,
If this state continues for a long time, there is a problem that an excessive force is applied to the piping and the life of the piping system is shortened.

からの作動信号も情報処理部７等へ送られる。When a fire occurs on a certain floor, the sprinkler head of the sprinkler 51 is opened by heat to release water. When water is discharged from the sprinkler head, the pressure in the pipe decreases and cannot be replenished in the pressure tank 12, and when the pressure in the pressure tank 12 falls below a predetermined pressure, the pressure switch 17 detects this and processes the pump start signal. Send it to the unit 7. The information processing unit 7 that has received the pump activation signal determines which water supply pump to activate based on a predetermined operation pattern, and sends a command to the pump control unit 6 to activate, for example, the water supply pump 3. Upon receiving this command, the pump control unit 6 starts the water supply pump 3. At the same time, the information processing section 7 outputs a command to open the motor-operated valve 16 provided on the main pipe 9 of the sprinkler facility. When the water supply pump 3 is started, the branch pipe 2 is connected via the main pipe 9.
The pressure in the branch pipe 2 gradually increases as the rotation speed of the water supply pump 3 increases. When water is discharged by the operation of the sprinkler head, a flow of fire-extinguishing water is generated in the branch pipe 2, and the flow opens the valve body in the water flow detection device 4, and the water channel formed by opening the valve body Pressure switch 8 that closes the contacts with the pressure of the fire water passed through
Is also sent to the information processing section 7 or the like.

Further, the information processing section 7 determines on which floor a fire has occurred based on the operation signal of the flowing water detection device 4, that is, the signal from the pressure switch 8. In the information processing unit 7,
The reference pressure required for extinguishing the fire is set in advance, and the information processing section 7 compares the pressure data sent from the pressure sensor 5 provided on the branch pipe on the floor where the fire has occurred with the reference pressure.

プを行う。However, here, when the push button of the fire hydrant 52 of the fire hydrant equipment 10 is pressed by instructing the start of the pump, the electric valve 16 of the fire hydrant equipment 10 is opened to supply water. When the fire hydrant valve is opened at 52, the pressure in the branch pipe 2 on the sprinkler equipment 1 side decreases accordingly. In response, the information processing section 7 increases the opening of the motor-operated valve 16 on the sprinkler facility 1 side. However, when the reference pressure is not reached even when the electric valve 16 is fully opened, the information processing section 7 determines that the capacity of the water supply pump 3 is insufficient,
It outputs a command to start another water supply pump 19 that is at rest. In response to this command, the water supply pump 19 is activated to back up the water supply pump 3. Then, the pressure rises again, and the reference hydraulic pressure is maintained by adjusting the electric valves 16. The command to start the second water supply pump 19 is issued even when the pressure in the branch pipe 2 does not increase due to the failure of the first water supply pump 3, and the water supply pump 19 backs up the water supply pump 3.

起動命令を出し、給水ポンプをバックアップする。In the present embodiment, as in the first embodiment, the water supply pump 3 is started by a pump start signal from the pressure switch 17 and the like, the electric valve 16 is opened to supply water to the branch pipe 2, and the water supply pressure is reduced. If the water supply runs short, the dosing water pump is started to perform backup. Here, in the case of the present embodiment, the reference pressure is set in advance for the pressure switch 13 of each floor. When the pressure in the branch pipe 2 reaches the reference pressure, the pressure switch 13 sends a signal to that effect to the information processing section 7. In this case, similarly to the first embodiment, when other fire extinguishing equipment is used, or when many sprinkler heads are activated, the detection signal cannot be received from the pressure switch 13 on the floor where the running water detection device is activated. Then, the information processing unit 7 issues a start-up command to the other suspended water supply pumps, and backs up the water supply pumps.

けることが望ましい。On the other hand, in the present embodiment, the pressure in the branch pipe 2 is controlled by controlling the opening of the motor-operated valve 16 in the same manner as in the first embodiment. The processing unit 7 issues a command to control the opening of the motor-operated valve 16 so that this signal is always sent. That is, when the pressure in the branch pipe 2 decreases and the signal from the pressure switch 13 is interrupted, the opening of the motor-operated valve 16 is increased to increase the pressure in the branch pipe 2, and when the signal is received again, the increase in the opening is stopped. . In this case, by setting the pressure switch 13 to have a contact point other than the reference pressure, more accurate opening control can be performed. That is, by sending a further signal when the pressure reaches a certain pressure higher than the reference pressure,
The increase in the opening of the motor-operated valve 16 is stopped, and the pressure in the branch pipe 2 can always be maintained at or above the reference pressure. In the first and second embodiments, in order to detect the pressure on the secondary side of the flowing water detecting device, the flowing water detecting device itself, that is, the pressure on the secondary side of the valve body is detected. It goes without saying that it may be anywhere on the secondary side of the flowing water detection device. However, it is desirable to provide a pressure sensor and a pressure switch near the flow detecting device or at the end of the branch pipe.

Activate the water supply pump which is inactive to perform backup. Here, in the case of the present embodiment, the data of the pressure required to obtain the reference pressure for each floor at the position of the pressure sensor 14 in order to obtain the reference pressure required for fire extinguishing is set in the information processing unit 7 in advance. ing. Then, when the fire occurrence floor is determined based on the operation signal from the pressure switch 8, the information processing section 7 determines the pressure data sent from the pressure sensor 14 and the pressure corresponding to the fire occurrence floor in the information processing section 7. Compare with data.
In this case as well, if another fire extinguishing facility cannot be used and the predetermined reference pressure cannot be maintained, the information processing unit 7 issues a start-up command to the other inactive pumps to back up the water supply pump.
