Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is directed to any one of a plurality of operation panels provided.
The present invention relates to a control device for fire extinguishing equipment that remotely controls fire extinguishing equipment such as water cannons.

(Prior art) In recent years, in large space structures with lightweight ceiling structures known as air domes, sprinkler fire extinguishing equipment that requires piping inside the ceiling cannot be installed, so large fire extinguishing areas are required. In order to control the water cannon, an on-site operation panel is installed near the water cannon, and a TV monitor is installed at a monitoring center located far from the water cannon installation location. However, a remote control panel is provided to control the water cannon, so that the water cannon can be remotely controlled either at the site or at the monitoring center depending on the fire situation.

By the way, when the water cannon is remotely controlled by multiple operation panels, in order to avoid duplication of control by multiple operation panels, select an operation panel that can be controlled at a specific location, such as on the monitoring center side, for example. A means is provided so that it cannot be operated using anything other than the selected operation panel.

(Problem to be solved by the invention) However, in the event of an emergency such as a fire, if the operation panel can only be selected at a specific location, There were problems in that the operating location could not be changed, and if a fire spread to the selected location, the selection function of the operating panel would be lost.

(Means for Solving the Problems) The present invention has been made in view of the above problems, and provides a system for remotely controlling a fire extinguishing device such as a water cannon using a control panel installed in multiple locations. It is an object of the present invention to provide a control device for fire extinguishing equipment that avoids confusion in operation when the fire occurs and allows selection of an appropriate operation panel depending on the fire situation.

In order to achieve this objective, the present invention introduces the concept of operation authority that allows the operation panel to occupy remote control of the fire extinguishing system and prohibits control by other operation panels. An operating right switch is provided to monopolize the remote control of the fire extinguishing system, and an operating right display means is provided to display the status of the operating right, and an operating right discrimination control unit discriminates the operating right switch signal from the operation panel. , the remote control line is switched so that the fire extinguisher can be remotely controlled only by the operation panel from which the operating power switch signal is obtained.

(Example) FIG. 2 is an explanatory diagram showing an outline of the control device of the present invention together with fire extinguishing equipment.

First, to explain the configuration, 1a, 1b, 1c,
1d is a water cannon, which receives a supply of extinguishing agent pressurized by a fire extinguishing pump 2 through a fire extinguishing pipe 3, and further includes a pneumatic unit to mix air when discharging the extinguishing agent to expand the spraying range of the extinguishing agent. Air pressure is supplied from the air pipe 4 to the air pipe 5. Note that the fire pump 2 is controlled by a pump control panel 6.

A water spray control panel 7 is provided for each of the water cannons 1a and 1d.

Furthermore, 2 water cannons 1a to 1d are directed toward the fire extinguishing area.
A stand of thermal radiation detectors 8a and 8b are installed, and the thermal radiation detectors 8a and 8b detect the position of the fire source by horizontal rotation drive by a motor and vertical scanning by rotation of a reflecting mirror. When a fire source is detected, the control calculation unit 9 outputs address information (position coordinates) indicating the location of the fire source.

In such fire extinguishing equipment, water cannons 1a-1
First, on-site operation panels 10a and 10 are installed near the water cannons 1a to 1d as operation panels for remotely controlling the
b, 10c, and 10d are installed. In addition, a center operation panel 12 is installed in a monitoring center 11 in a basement or the like that is far from the installation location of the water cannons 1a to 1d, and if we take as an example a ball game stadium equipped with an air dome ceiling as a location for installing fire extinguishing equipment, There is also an on-site operation panel 1 in the on-site monitoring room 13, which is installed in a place where the on-site monitoring room can be monitored.
4 will be installed.

Furthermore, an automatic control unit 15 using a CPU is installed in the monitoring center 11, and the automatic control unit 15 detects the fire source obtained by the calculation control unit 9 based on the detection outputs of the thermal radiation detectors 8a and 8b. Position information is input via the central processing unit 16, and any one of the water cannons 1a to 1d is operated under program control.
The system automatically controls fire extinguishing by selecting one and releasing extinguishing agent.

A central processing unit 16 installed in the monitoring center 11 is operated by an operation right discrimination control circuit for discriminating the switch signal of the operation right switch provided on each operation panel and occupying the operation right, which will be explained later. Any one of the water spray control panels 7a to 7d of the water cannons 1a to 1d whose remote control line from the panel is selected
Equipped with a switching unit for switching connection to the

The output of the operating power switch provided for each is input.

Here, the center operation panel 12 has a device configuration shown in FIG. 3, for example. First, the center operation panel 12 is provided with an operation right switch 20, and when the operation right switch 20 is turned on, an operation right switch signal S1 is sent to the operation right discrimination control circuit 18 in the central processing unit 16 shown in FIG. Output.

Further, the center operation panel 12 is provided with a mode selection section 21 for selecting a control mode of the water cannon, and in this embodiment, three modes are selected: an automatic mode 21a, a remote mode 21b, and an on-site mode 21c. be able to. Here automatic mode 21a
is a control mode of the water cannon by the automatic control unit 15, remote mode 21b is a remote control mode of the water cannon by the center operation panel 12, and field mode 21c is a control mode of the water cannon by the center operation panel 12.
The selection signals A1 to A3 for these three control modes are given to the operating right discrimination control circuit 18 of FIG. 1 together with the operating right switch signal S1. Furthermore, the center operation panel 12
is provided with a remote control section 22 that outputs a control signal for remotely controlling the water cannons 1a to 1d, and in this embodiment, a right rotation control signal B of the water cannons is provided.
1. A case is taken as an example in which four control signals are output: a left turn control signal B2, a short-distance extinguishing agent selection signal B3, and a long-distance extinguishing agent selection signal B4. Furthermore, the center operation panel 12 is provided with a water cannon selection section 23, which selects remote and on-site modes 21b and 21c other than the automatic mode 21a in the mode selection section 21.
Any one of the four water cannons 1a to 1d
You can select one as the operation target.

On the other hand, the center operation panel 12 has an operation authority display section 24.
A lamp is provided to indicate whether the monitoring panel having the operating authority determined by the operating authority discrimination control circuit 18 is in the center, outside the field, or on-site. Furthermore, the operating authority display section 24 has a built-in alarm buzzer, and when the operating authority is switched, the buzzer sounds to call attention. Furthermore, the operating authority display section 2
In-field and on-site operation authority signals C3 and C4 for 4
is input to the OR gate 25, and the output of the OR gate 25 and the output S1 of the operating power switch 20 are input to the AND gate 26, and are applied to the remote mode setting section 21b in the mode selection section 21. This circuit consisting of the OR gate 25 and the AND gate 26 operates when the operation authority is returned to the center operation panel 12 from another operation panel, that is, the on-site operation panel 14 or the on-site operation panels 10a to 10d, by turning on the operation authority switch 20. A control mode selection means is configured to ensure that the control mode when the operating authority is returned is always the remote mode 21b.

The structure of the center operation panel 12 shown in FIG. 3 is also the same for the on-site operation panel 14.

FIG. 4 is an explanatory diagram showing the device configuration of the field operation panels 10a to 10d, and the center operation panel 1 of FIG.
2, the operating power switch 30 and the mode selection section 3
1. Includes a remote control section 32 and an operation right display section 34. Here, the mode selection section 31 selects the on-site mode 31a.
It has two selection modes: and manual mode 31b,
On-site mode 31a selects remote control of the water cannon using the on-site operation panel itself, and manual mode 31b stops controlling the water cannon from all remote control panels, including the on-site operation panel, and selects the manual handle provided on the water cannon. This allows operations such as In addition, in the case of the field operation panels 10a to 10d, since acquiring the operation authority means the field mode 31a in the mode selection section 31, the center operation panel 12
There is no mode selection means for selecting a specific control mode when the operating authority is acquired.

Referring again to FIG. 1, the remote control unit 22 (third
(see figure) is given to the switches 40b and 40c of the central processing unit 16, and a similar control line is also drawn out from the automatic control unit 15. is inputting the control line from.
The outputs of the control lines from the switching devices 40a to 40c are connected in common, and are inputted in parallel to each of the switching devices 42a to 42d provided corresponding to the water discharge control panels 7a to 7d.

Furthermore, the control line from the remote control unit 32 (see FIG. 4) provided on the field operation panels 10a to 10d is as follows.
The inputs are connected to each of the switching devices 44a to 44d, and the outputs of the switching devices 44a to 44d are commonly connected to the outputs of the corresponding switching devices 42a to 42d to supply control signals to the water discharge control panels 7a to 7d. .

The operating right discrimination control circuit 18 operates by switching switches 40a to 40c and 44a to 44a provided in the central processing unit 16.
44d, the control line is switched and connected between any one of the operation panels (including the automatic control unit 15) and any one of the water discharge control panels 7a to 7d based on the operating authority.

On the other hand, the switching devices 42a to 42d are connected to the automatic control unit 15, the center operation panel 12, or the on-site operation panel 14.
The water cannon selection circuit 46 is switched by the water cannon selection signal 46 to select the water cannon.
The water cannon selection circuit 46 receives a selection signal from the water cannon selection section 23 (see FIG. 3) provided on the center operation panel 12 and the on-site operation panel 14, and a water cannon from the automatic control unit 15. A selection signal is provided. Next, selection control of the switching devices 40a to 40c and 44a to 44d by the operating right discrimination control circuit 18 is as follows.

(1) When automatic mode is selected on the center operation panel 12 or on-site operation panel; switch 40b, 40c and switch 44a to 44
d is off and only the switch 40a is on.

(2) When the center operation panel 12 acquires operation authority; the switches 40a, 40c and the switches 44a to 44
d is off, and only the switch 40b is on.

(3) When the on-site operation panel 14 acquires operation authority; the switching devices 40a, 40b and the switching devices 44a to 44
d is off, and only the switch 40c is on.

(4) When any one of the field operation panels 10a to 10d acquires operation authority; the switches 40a to 40c are turned off. Any one of the switches 44a to 44d corresponding to the on-site operation panel that has acquired operation authority is turned on, and the others are turned off.

Switching control accompanying acquisition of such operating authority is performed by switching signals C1 to C4, and furthermore, switching signals C1 to C4 are transmitted to the center operation panel 12 and the on-site operation panel 1.
4 and the on-site operation panels 10a to 10d to display the operating authority in the operating authority display section 24 (see FIG. 3) and the operating authority display section 34 (see FIG. 4).

Next, the control operation of the above embodiment will be explained.

If the center operation panel 12 now has the operation authority, as is clear from the center operation panel 12 shown in FIG. selection, control of the water cannon by the remote control unit 22;
Further, any selection of water cannons by the water cannon selection section 23 can be remotely controlled.

If, for example, the operating authority switch of the on-site operating panel 14 is turned on while the operating authority on the center operating panel 12 has been acquired, the operating authority discriminating control circuit 18 of the central processing unit 16 will control the operating authority on the on-site operating panel 1.
4, the switching device 40b, which had been in the on state, is turned off, and the switching device 40c is turned on at the same time. Switching devices 42a to 42d based on the water cannon selection signal
Turn on any one of them, and connect the control line from the on-site operation panel 14 to the water discharge control panels 7a to 7 through the switch 40c and any one of the switches 42a to 42d.
7d.

Furthermore, if one of the on-site operation panels 10a to 10d, for example, the operation right switch 30 of the on-site operation panel 10a, is turned on with the operation authority acquired on the on-site operation panel 14, the operation from this on-site operation panel 10a Upon receiving the right switch signal, the operation right discrimination control circuit 18 turns off all the switches 40a to 40c, and at the same time turns on only the switch 44a corresponding to the field operation panel 10a, and switches the control line from the field operation panel 10a. It is switched and connected to the corresponding water discharge control panel 7a via the container 44a.

Furthermore, if the operation authority switch 20 of the center operation panel 12 is turned on with the operation authority acquired on the field operation panel 10a, the operation authority discrimination control circuit 18
By turning on the switch 40b again, the control line from the center operation panel 12 is switched to the switch 4 selected by the switch 40b and the water cannon selection circuit 46.
It is switched and connected to any one of the corresponding water discharge control panels 7c to 7d via any one of 2a to 42d.

When the operation authority is returned from another operation panel to the center operation panel 12 in this way, as shown in FIG. Therefore, when the operating power switch 20 is turned on, the AND gate 26 generates an H level output, and the control mode of the mode selection section 21 is changed to the H level of the AND gate 26.
The level output forcibly switches to the remote mode 21b and returns the operating authority to the center operation panel 12.

In this way, the control device of the present invention has a center operation panel 12, an on-site operation panel 14, and an on-site operation panel 1.
In any case from 0a to 10d, if necessary, the operation authority to remotely control the water cannon can be obtained from the own operation panel by turning on the operation switch, and the acquisition status of this operation authority varies depending on each operation. Since it is displayed on the panel, it is immediately known which operation panel has the operating authority, and a more appropriate decision can be made when transferring the operating authority.

In order to enable communication between the operators of each operation panel when the operating authority is transferred, it is desirable to provide communication equipment such as an intercom on each operation panel.

In addition, although the above embodiment takes remote control of a water cannon as an example, the present invention is not limited thereto, and can be applied as it is to remote control of an appropriate fire extinguishing system, and the number and operation of fire extinguishing systems can be adjusted as is. There are no restrictions on the number of discs.

(Effects of the Invention) As described above, according to the present invention, each of the plurality of operation panels is provided with an operation power switch for monopolizing the remote control of a fire extinguishing device such as a water cannon, and the operation power status is An operation authority display means is provided to display the operation authority switch signal from the operation panel using an operation authority discrimination control unit, and the fire extinguishing system is remotely controlled only by the operation panel from which the operation authority switch signal is obtained. Because the remote control line from the operation panel was switched to make it possible, the remote control line from the operation panel could be switched between the on-site operation panel installed near the water cannon, and the monitoring panel located away from the water cannon installation location, such as the monitoring center or on-site monitoring room. Even in a fire, water cannons can be remotely controlled by obtaining operational authority according to the fire situation. For example, even if a fire develops and the operator evacuates while on-site operation is in progress, there is no need to operate a switch on the on-site operation panel. It is possible to remotely control the water cannon by obtaining the right to control the water cannon, prevent confusion in operation when the fire extinguishing equipment can be remotely controlled using multiple operation panels, and perform appropriate fire extinguishing activities.

In addition, if the operation panel has multiple control modes for the fire extinguishing system, when the operation authority is returned, it will select a predetermined control mode, for example, the same remote control mode as the control mode before acquiring the operation authority. This prevents the water cannon from being controlled by switching to a different control mode, such as automatic control mode, by obtaining operating authority, which is completely different from the previous remote control. Coordination of fire extinguishing activities can be carried out appropriately as the operational authority is transferred.
