Description

The present invention relates to a map display device for a fire extinguishing facility that displays a section or the like discharged from a head by a fire in a sprinkler fire extinguishing facility or a foam fire extinguishing facility on a list map of a warning area.

  Conventionally, the sprinkler equipment is connected to the closed sprinkler head installed in the warning area via the control valve and the flow detection device, and the open sprinkler head is opened by receiving the hot air current from the fire. Fire extinguishing is started by discharging water from (Patent Document 1).

  In addition, in the foam extinguishing equipment, the piping from the foam extinguishing agent supply equipment is connected to the simultaneous opening valve installed in the warning area through the control valve and the water flow detection device, and further the piping on the secondary side of the simultaneous opening valve. Is connected to the foam head and the sensing pipe is connected to the sensing head, and fire extinguishing is started by supplying and releasing the foam extinguishing agent to the foam head by opening the simultaneous opening valve with the operation of the sensing head (Patent Document) 2).

  In such a fire extinguishing system, monitoring and control are performed by treating the area divided for each running water detector installed on the primary side of the head as a protection zone, not for each head installed in the warning area. ing.

  When the sprinkler fire extinguishing equipment or foam fire extinguishing equipment starts to extinguish, the sprinkler fire extinguishing equipment has a water source for water discharge for 20 minutes and the foam fire extinguishing equipment has a water source for 10 minutes. Fire extinguishing often ends.

  In this way, if you want to stop the water discharge after the fire is extinguished within the time when the water source is secured, the fire prevention manager, the disaster prevention center staff or the fire brigade will confirm the fire extinguishing at the fire site, then the primary side of the water flow detection device The water discharge can be stopped by closing the control valve provided for each protection section.

  Moreover, even when an earthquake or the like occurs and water is accidentally discharged due to damage to a fire extinguishing pipe rather than a fire, the water discharge can be stopped by closing the control valve.

  The control valve used to stop the water discharge of such a fire extinguishing facility is installed in a dedicated room near the protective compartment in the building, and a “sprinkler control valve room” is displayed on the door of this room.

  On the other hand, on the display screen of the disaster prevention center's general operation panel and the map display device installed in the alert area, when fire extinguishing is started with the fire extinguishing equipment, the protection area where the head is activated is displayed in the list of alert areas. I am doing so.

  However, if the fire prevention manager or the disaster prevention center staff confirms that the fire has been extinguished and stops the water discharge at the fire site, the control screen is not displayed on the display screen of the disaster prevention center's general operation panel or the map display device installed in the warning area. The chamber is not shown, and it is necessary to check with a booklet provided separately, and it takes time and effort to know the location of the control valve chamber.

  In this case, since fire fighting equipment is regularly inspected by an external fire fighting equipment engineer, the fire prevention manager and the disaster prevention center staff know the location of the control valve room. Few.

  Since the control valve room is not a room for daily use, it is installed in a place where it is difficult to approach in the narrowest room in the building, for example, in the toilet or in a place where it does not touch daily flow lines. Even if the location of the control valve chamber is known, the location cannot be quickly found, and it may take time to reach the control valve chamber.

  Furthermore, the control valve chamber may be locked so that a general user cannot enter the room by mistake, and the locked valve chamber may not be noticed unless the control valve chamber is reached. , It may take time and effort to unlock and enter the room.

  Therefore, even if it is desired to close the control valve in order to stop water discharge from the head, it is difficult to understand the location of the control valve chamber, and it takes much time to stop the control valve. In addition, when the control valve is closed and the water discharge is stopped, all the water source is consumed, and if the water loss occurs or a fire occurs again after the fire is extinguished, the fire extinguishing equipment cannot be operated normally. There is a problem.

It is an object of the present invention to provide a map display device for a fire extinguishing facility capable of quickly and surely grasping a control valve chamber in which a control valve for stopping the water discharge of the fire extinguishing facility is installed and capable of stopping the water discharge by a closing operation. .

The map display device of the fire extinguishing equipment according to the present invention displays a list map of the warning areas in which the protection compartments and the control valve chambers are separately displayed by the map display means, and can selectively display the water discharge symbol for each protection compartment. The valve chamber symbol can be selectively displayed for each control valve chamber, and when the control means detects water discharge from the head, the map display means is controlled, and the water discharge symbol is displayed in the protected protection area in the list map. Since the valve chamber symbol is displayed in the control valve chamber in the list map corresponding to the protected section that has been displayed and discharged, the symbol map of the protected section that started extinguishing is now supported in the list map of the warning area By observing the symbol display that indicates the control valve chamber, it is possible to easily and easily grasp the location of the control valve chamber in which the control valve is installed in the building. By closing the valve, water discharge is stopped immediately, water loss and unnecessary consumption of water sources are suppressed, and it is possible to operate fire extinguishing equipment normally in the event of a fire again after extinguishing. .

(Effect of delay display of control valve chamber by running water detection)
In addition, the control means controls the map display means when a predetermined time has elapsed after receiving the water flow detection signal from the water flow detection device, and controls the control valve chamber corresponding to the drained protection section in the list map. Since the valve chamber symbol is displayed, when fire extinguishing is started by water discharge from the head of the fire extinguishing equipment, there is no need to stop water discharge by closing the control valve. In the state where water has actually been discharged from the head after the passage, it is possible to display the symbol indicating the control valve chamber corresponding to the protective section that is discharging water and to indicate the location.

(Displays control valve chamber by detecting secondary pressure reduction)
The control means controls the map display means when receiving a decompression detection signal from the decompression detector provided on the secondary side of the water flow detection device, and controls corresponding to the protected compartment that has been discharged in the list map. Since the valve chamber symbol is displayed in the valve chamber, when water is discharged from the head, the pressure in the piping will drop, so this corresponds to the protective section that is discharging water while the water is actually discharged from the head. It is possible to display the symbol indicating the control valve chamber and indicate its location.

(Displays control valve chamber when no fire is detected)
In addition, the control means controls the map display means when the fire signal received from the fire detector provided in the protection section corresponding to the head water discharge is not detected, and the discharged water protection in the list map is controlled.

Further, it is possible to display a symbol indicating the control valve chamber when it is necessary to stop water discharge such as when water is discharged due to malfunction or the like.

(Display of control valve chamber by switch operation)
In addition, when the control means detects acceptance of the control valve chamber display instruction by the switch operation, the control means controls the map display means so that the control valve chamber corresponding to the protection section in the list map corresponding to the water discharge of the head. Since the valve chamber symbol is displayed, the protective section that is discharging water by operating the switch provided on the map display device in the state that the protective section that has started discharging water by the fire extinguishing equipment is displayed as a symbol. It is possible to display a symbol indicating a control valve chamber corresponding to the above.

(Effects of co-displaying the water discharge symbol and valve chamber symbol)
In addition, the control means controls the map display means to display the water discharge symbol in the protective compartment where the water is discharged in the list map and when displaying the valve chamber symbol in the control valve chamber corresponding to the discharged protective compartment, Since the display showing the cooperation between the water discharge symbol and the valve chamber symbol is performed, the cooperative relationship between the protection compartment that started the water discharge and the control valve chamber corresponding to this, for example, connecting both symbols in a line display, etc. This clearly displays the relationship between the protective compartment that discharges water and the control valve chamber that stops the water discharge.For example, an earthquake occurs and multiple protective compartments accidentally discharge water with the same floor due to damage to the firefighting piping. In such a case, it is possible to accurately grasp the location of the control valve chamber corresponding to each protection section and perform the control valve closing operation.

(Effects of valve chamber symbol indicating door with lock)
In addition, when a lock door is installed in the control valve chamber and locked, the control means controls the map display means to display a symbol indicating the lock door as the valve chamber symbol. By looking at the valve chamber symbol indicating the chamber, you can see that the door of the control valve chamber is locked, and by bringing the key you are managing, open the door of the locked control valve chamber and open the control valve It is possible to quickly stop the water discharge by the closing operation.

(Effect of map display using map panel)
The map display means can display a map panel on which a warning area list map is drawn, a water discharge section indicator lamp that can display a water discharge symbol for each protection section of the map panel, and a valve chamber symbol for each control valve chamber of the map panel A control valve chamber indicator light, and when the control means detects the water discharge from the head, the control means drives the water discharge compartment indicator light to display the water discharge symbol in the discharged water protection compartment in the map panel, Since the valve chamber symbol is displayed in the control valve chamber corresponding to the protective compartment that has been discharged by driving the control valve chamber indicator light, the protective compartment has been discharged in the list map showing the warning area with a relatively simple structure. And a symbol display indicating a control valve chamber corresponding to the control valve chamber.

(Effect of map display using liquid crystal display panel)
Further, the map display means is a liquid crystal display panel displaying a list map of the warning area, and when the control means detects water discharge from the head, the liquid crystal display panel is driven to discharge water in the list map. Since the water discharge symbol is displayed in the protective compartment and the valve chamber symbol is displayed in the control valve chamber in the list map corresponding to the discharged protective compartment, display data including the division display of the protective compartment and the control valve chamber is displayed. By preparing, it is possible to easily and flexibly display a symbol indicating a protected section that has discharged water and a control valve chamber corresponding thereto in the list map.

(Effect of cooperation with security system)
In addition, when a lockable door is installed and locked in the control valve chamber, the control means controls the map display means to display a symbol indicating the lockable door as the valve chamber symbol and opens it to the security system. Since the lock control signal is sent and the target control valve chamber is unlocked, even if the control valve chamber is locked, the control valve chamber of the target is automatically activated in cooperation with the security system. The door is unlocked, and it is possible to enter the control valve chamber and close the control valve without managing the key or bringing the key.

As shown in FIG. 5, the map display device 40 includes a control unit 50, a section receiving unit 52, a water discharge section indicator lamp 65 provided for each of the protection sections A1 to An of the map panel, and each of the control valve chambers B1 to Bn of the map panel. The control valve chamber indicator lamp 66 and the valve chamber indicator switch 70 provided in the above are provided.

  The control unit 50 of the map display device 40 functions as a control means, for example, a function realized by executing a program. As the hardware, a CPU, a memory, a computer circuit having various input / output ports, and the like are used. .

  A flow detection signal from the flow detector 42 of the flow detection device 24 provided in each of the protection sections A <b> 1 to An can be input to the control unit 50 via the section reception unit 52. Although the fire detector 36 is installed in the protection sections A1 to An corresponding to the flowing water detection device 24, it is shown in the flowing water detection device 24 for convenience of explanation.

  When the closed sprinkler head in the protection section Ai is activated by the fire and starts to discharge water, the control unit 50 detects the reception of the flowing water detection signal from the flowing water detector 42 provided in the flowing water detection device 24, that is, from the head. When the water discharge is detected, the water discharge section indicator lamp 65 provided in the corresponding protection section Ai of the map panel 48 of FIG. 2 is turned on to display the water discharge symbol 60 in an illuminated manner, and the water discharge symbol 60 of FIG. The control valve chamber indicator lamp 66 provided in the control valve chamber Bi of the map panel 48 is turned on to display the valve chamber symbol 62 in an illuminated manner.

  Here, the display control of the valve chamber symbol 62 by the control unit 50 includes the following control mode 1 and control mode 2.

(Control mode 1)
In the control mode 1 by the control unit 50, when a predetermined time has elapsed after receiving the water flow detection signal from the water flow detection device 24, the control valve chamber indicator lamp 66 is driven to turn on and discharge water in the list map. Control is performed to display the valve chamber symbol 62 in the control valve chamber Bi corresponding to the protection section Ai.

  FIG. 6 is a block diagram showing an example of a functional configuration for realizing control in control mode 1 by the control unit 50 provided in the map display device of FIG.

  As shown in FIG. 6, the control unit 50 includes drivers 72 and 80, a delay unit 74, an AND circuit 76, and an OR circuit 78. When the flowing water detector 42 detects flowing water, the flowing water detection signal E <b> 1 that becomes H level is input to the driver 72, and the water discharge section indicator lamp 65 is driven to light by the output of the driver 72.

  The flowing water detection signal E1 that becomes H level is input to the delay unit 74, output after a predetermined delay time has elapsed, and is input to the driver 80 via the OR circuit 78. The output of the driver 80 displays the control valve chamber display. The lamp 66 is driven to turn on.

  For this reason, when fire extinguishing is started by water discharge by the operation of the closed type sprinkler head, it is not necessary to stop water discharge by closing operation of the control valve 25. The control valve chamber corresponding to the protective section that is discharging water is displayed after the sprinkler head that has been activated after a predetermined time determined by the delay time of the delay unit 74 has actually been discharged. Illumination display of the valve chamber symbol 62 shown can be performed to indicate the location.

  Further, the control unit 50 inputs the flowing water detection signal E1 and the switch signal Es of the valve chamber display switch 70 to the AND circuit 76, and the valve chamber display switch in a state where the flowing water detection signal E1 which is at the H level is input. When the switch 70 is turned on and the switch signal Es becomes H level, the output of the AND circuit 76 becomes H level and is input to the driver 80 via the OR circuit 78, and the control valve chamber indicator lamp 66 is turned on by the output of the driver 80. Drive on.

  For this reason, if the person in charge turns on the control valve chamber display switch 70 in a state where the water discharge symbol 60 is illuminated in the protection section but the valve chamber symbol 62 is not displayed, the valve chamber corresponding to the water discharge symbol 60 is displayed. The symbol 62 is illuminated to enable confirmation of the location of the control valve chamber on the map map list.

  The functional configuration of the control mode 1 in FIG. 6 can be similarly realized by program control by a computer.

(Control mode 2)
The control mode 2 is controlled by the control unit 50 for a predetermined time after receiving the running water detection signal from the running water detection device 24 on the condition that the fire signal from the fire detector 36 provided in the protection section is not received. When the control valve chamber indicator lamp 66 has elapsed, the control valve chamber indicator lamp 66 is driven to turn on and display the valve chamber symbol 62 in the control valve chamber Bi corresponding to the discharged protection section Ai in the list map.

  FIG. 7 is a block diagram showing an example of a functional configuration for realizing control in control mode 2 by the control unit 50 provided in the map display device of FIG.

  As shown in FIG. 7, the control unit 50 includes drivers 72 and 80, a delay unit 74, an AND circuit 76, and an OR circuit 78. This point is the same as the control mode 1 in FIG. A circuit 82 and an AND circuit 84 are provided.

  A flowing water detection signal E1 that becomes H level when flowing water is detected by the flowing water detector 42 is input to the driver 72, and the water discharge section indicator lamp 65 is driven to light by the output of the driver 72.

  Further, the flowing water detection signal E <b> 1 that becomes H level is input to the delay unit 74, output after a predetermined delay time has elapsed, and input to the AND circuit 84. The fire signal E2 is inverted by the inverter circuit 82 and input to the AND circuit 84. When fire detection by the fire detector is not performed, the fire signal E2 is at the L level, is inverted by the inverter circuit 82 and becomes the H level, and the AND circuit 84 is allowed.

  For this reason, when the flowing water detection signal E2 that becomes H level due to water discharge from the sprinkler head is input in a state where the fire signal not detected by the fire detector is L level, the predetermined time determined by the delay time of the delay unit 74 After that, the H level output of the delay unit 74 is input to the driver 80 via the AND circuit 84 and the OR circuit 78, and the control valve chamber indicator lamp 66 is driven to light by the output of the driver 80.

For this reason, since it is not necessary to stop the water discharge when a fire signal is received, the valve chamber symbol 62 indicating the control valve chamber that stops the water discharge by the closing operation of the control valve 25 is not displayed, and the fire is caused by the fire extinguishing. When the signal is not received and it is necessary to stop the water discharge, the valve chamber symbol 62 indicating the control valve chamber can be displayed.

  Note that the display control of the valve chamber symbol 62 by turning on the valve chamber display switch 70 is the same as in the control mode 1 of FIG. 6 and the water discharge symbol 60 is illuminated and displayed in the protection section. When the person in charge turns on the control valve chamber display switch 70 in the state where 62 is not displayed, the valve chamber symbol 62 corresponding to the water discharge symbol 60 is illuminated and displayed, and the control valve chamber on the list map of the map panel is displayed. The location can be confirmed.

FIG. 11 is a block diagram showing an example of the functional configuration of the control unit provided in the map display device of FIG. 10, and FIG. 12 is a control unit provided in the map display device of FIG. It is the block diagram which showed the other example of the functional structure.

  In the sprinkler fire extinguishing equipment shown in FIG. 9, the depressurization detection signal is output to the water flow detection device 24 by detecting that the secondary side pressure due to water discharge from the closed sprinkler head 26 has dropped below a predetermined value. A decompression detector 44 is provided, and a decompression detection signal from the decompression detector 44 is transmitted to the map display device 40 via the sprinkler control panel 34. Since the other configuration is the same as that of the sprinkler fire extinguishing equipment of FIG. 1, the same reference numerals are given and the description thereof is omitted.

  The map display device 40 has the functional configuration shown in FIG. 10, and the decompression detection signal from the decompression detector 44 provided in the flowing water detection device 24 is sent to the section receiving unit 52 of the map display device 40 via the sprinkler control panel 34. Received and input to the control unit 50. Further, the map list 48 is used for the list map of the alert area as in the case of FIG.

  Here, the display control of the valve chamber symbol 62 by the control unit 50 includes the following control mode 1 and control mode 2.

(Control mode 1)
In the control mode 1 by the control unit 50 of FIG. 10, when a decompression detection signal is received from the decompression detector 44, the control valve chamber indicator lamp 66 is driven to turn on and discharge to the protected section Ai in the list map. Control is performed to display the valve chamber symbol 62 in the corresponding control valve chamber Bi.

  FIG. 11 is a block diagram showing an example of a functional configuration for realizing control in control mode 1 by the control unit 50 provided in the map display device of FIG.

  As shown in FIG. 11, the control unit 50 includes drivers 72 and 80, an AND circuit 76, and an OR circuit 78. The flowing water detection signal E1 which becomes the H level from the flowing water detector 42 is input to the driver 72, and the water discharge section indicator lamp 65 is driven to light by the output of the driver 72.

  On the other hand, the decompression detection signal E3 which becomes the H level from the decompression detector 44 is input to the driver 80 via the OR circuit 78, and the control valve chamber indicator lamp 66 is driven to light by the output of the driver 80.

  For this reason, when fire extinguishing is started by water discharge by the operation of the closed type sprinkler head, first, the water flow detector 42 detects the water flow accompanying the head water discharge and outputs the water flow detection signal E1, thereby corresponding to the list map. The valve chamber indicating the control valve chamber corresponding to the discharged protected area by displaying the water discharge symbol 60 in the protection section and subsequently outputting the pressure drop detection signal E3 for the pressure drop in the secondary side piping of the water flow detection device 24. The symbol 62 can be displayed to indicate its location.

  Further, the control unit 50 inputs the flowing water detection signal E1 and the switch signal Es of the control valve chamber display switch 70 to the AND circuit 76, and displays the control valve chamber display in a state where the flowing water detection signal E1 which is at the H level is input. When the switch 70 is turned on and the switch signal Es becomes H level, the output of the AND circuit 76 becomes H level and is input to the driver 80 via the OR circuit 78, and the control valve chamber indicator lamp 66 is output by the output of the driver 80. Drive on. This is the same as FIG.

(Control mode 2)
In the control mode 2 control by the control unit 50 of FIG. 10, when a decompression detection signal is received from the decompression detector 44 on the condition that a fire signal from the fire detector 36 provided in the protection section is not received. Then, the control valve chamber indicator lamp 66 is turned on to perform control for displaying the valve chamber symbol 62 in the control valve chamber Bi corresponding to the protected section Ai that has discharged water in the list map.

  FIG. 12 is a block diagram showing an example of a functional configuration for realizing control in control mode 2 by the control unit 50 provided in the map display device of FIG.

  As shown in FIG. 12, the control unit 50 is provided with drivers 72 and 80, an AND circuit 76, and an OR circuit 78. This point is the same as the control mode 1 in FIG. A circuit 84 is provided.

  On the other hand, the decompression detection signal E 3 that is at the H level from the decompression detector 42 is input to the AND circuit 84. The fire signal E2 is inverted by the inverter circuit 82 and input to the AND circuit 84. When fire detection by the fire detector is not performed, the fire signal E2 is at the L level, is inverted by the inverter circuit 82 and becomes the H level, and the AND circuit 84 is allowed.

  For this reason, when the fire signal not detected by the fire detector is in the L level, the decompression detection signal E3 that detects the decompression due to the decrease in the secondary pressure due to the water discharge from the sprinkler head and becomes the H level is input. Then, the signal is input to the driver 80 through the AND circuit 84 and the OR circuit 78, and the control valve chamber indicator lamp 66 is driven to light by the output of the driver 80.

  Note that the display control of the valve chamber symbol 62 by turning on the control valve chamber display switch 70 is the same as in the control mode 1 of FIG.

  Further, as the map display device 40 shown in FIGS. 9 and 10, as shown in FIG. 9, a liquid crystal display panel 100 may be used.

  The functional configurations of the control mode 1 in FIG. 11 and the control mode 2 in FIG. 12 can be similarly realized by program control by a computer.
