Abstract
Description
[Technical Field]
[0001] The present invention relates to a fire hydrant device that stores a fire hose, a fire extinguisher, etc. and is installed in a tunnel, and a fire extinguisher box that stores a fire extinguisher and is installed in a tunnel. [Background technology]
[0002] Conventionally, fire hydrants have been installed as emergency tunnel equipment in tunnels such as expressways and expressways. A fire hydrant system consists of a housing with a fire hydrant door, a fire hose with a nozzle attached to the end, and valves including a fire hydrant valve, housed in a fire hydrant housing section, and a fire extinguisher housing section with a fire extinguisher door, which houses, for example, two fire extinguishers. Furthermore, fire hydrant systems are generally installed by embedding boxes into the tunnel wall at intervals of, for example, 50 meters along the length of the tunnel.
[0003] The fire hydrant device is also equipped with an emergency notification device, which is equipped with a red indicator light, a transmitter, a response lamp, and a telephone jack on the notification device door located between the fire hydrant storage section and the fire extinguisher storage section.
[0004] The red indicator light stays on at all times, allowing the location of the fire hydrant device to be confirmed from a distance. When a fire breaks out and the transmitter is pressed to turn on the push button switch, a fire notification signal is sent to a disaster prevention receiving panel installed in an electrical room or the like, and a fire alarm is output. The disaster prevention receiving panel that has output the fire alarm sends a response signal to the emergency notification device, causing the red indicator light to flash and the response lamp to light up, making it possible to confirm that the fire notification signal has been received on the disaster prevention receiving panel side (Patent Document 1).
[0005] Furthermore, because road users are generally unfamiliar with operating fire hydrant devices, when a road user opens the hydrant door of a fire hydrant device, an instruction manual showing how to operate the device is visible using pictures and text. However, in an emergency situation such as a fire outbreak, it can be difficult to operate the fire hydrant device while reading the instruction manual, so fire hydrant devices have been proposed that provide instructions on how to operate the device using displays and audio (Patent Documents 2 and 3). [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-102380 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-310785 [Patent Document 3] Japanese Patent Application Publication No. 2019-118423 Summary of the Invention [Problem to be solved by the invention]
[0007] Incidentally, if a vehicle fire occurs in a tunnel due to an accident or the like, road users will operate a transmitter to report the fire, and then use a fire hydrant or fire extinguisher to put out the fire.
[0008] However, in an emergency situation such as a fire, some road users may use fire hydrants or fire extinguishers to extinguish the fire without operating a transmitter to report the fire. If the transmitter is not operated, a fire alarm will not be issued on the disaster prevention receiving panel, and the road administrator will not be aware of the fire. Furthermore, when the disaster prevention receiving panel receives both a fire signal from the fire detectors installed at 25-meter or 50-meter intervals along the length of the tunnel and a fire report signal from the transmitter, it activates other emergency equipment, such as a no-entry warning sign installed at the tunnel entrance. However, if the transmitter is not operated, the other emergency equipment will not be activated, which could seriously hinder operation and management in the event of a fire.
[0009] Furthermore, the operating instructions provided by conventional fire hydrant devices consist of instructions for operating procedures such as opening a tilt-forward door, removing the nozzle of the fire hose, and opening the hydrant valve to spray water. However, there is no mention of reporting a fire by operating a transmitter before operating the hydrant, which leaves open the problem of some road users operating the hydrant device to carry out firefighting activities without operating the transmitter to report a fire.
[0010] This problem also applies to fire extinguisher boxes equipped with emergency notification devices that are installed as emergency equipment in low-ranking tunnels that are classified based on traffic volume, tunnel length, etc.
[0011] The present invention aims to provide a fire hydrant device and a fire extinguisher box that enable appropriate operation and management of emergency tunnel equipment in the event of a fire, even if firefighting activities are carried out using a fire hydrant or fire extinguisher without operating a transmitter. [Means for solving the problem]
[0012] (Fire hydrant device 1: Firefighting using a fire hydrant) The present invention provides a fire hydrant device that is installed in a tunnel and includes at least a fire hydrant device including a fire hose with a nozzle, and an emergency notification device including a transmitter, A control unit is provided that outputs audio and / or visual operation guidance to prompt the operator to operate the transmitter when an operation to open the fire hydrant door is detected without the operation of the transmitter being detected.
[0013] (Automatic transmission of fire alarm signals) When the control unit detects operation of a specified fire hydrant device following the opening of the fire hydrant door, it sends a fire notification signal to the disaster prevention receiving panel, just as if the transmitter were operated, and outputs a fire alarm.
[0014] (Operation of prescribed fire hydrant equipment) The operation of a specific fire hydrant device that follows the opening operation of the fire hydrant door is the nozzle removal operation.
[0015] (Detection of fire hydrant door opening operation) The fire hydrant door is an open detector that detects the opening of the fire hydrant door; a contact detector that detects human contact with the opening / closing handle of the fire hydrant door; is established, The control unit detects that the fire hydrant door has been opened when both the door opening by the open detector and the door contact by the contact detector are detected.
[0016] (Fire hydrant device 2: Firefighting using a fire extinguisher) The present invention provides a fire hydrant device that is installed in a tunnel and includes a fire hydrant device including a fire hose with a nozzle, a fire extinguisher, and an emergency notification device including a transmitter, A control unit is provided that outputs audio and / or visual operation guidance to prompt the user to operate the transmitter when an operation to open the fire extinguisher door is detected without the operation of the transmitter being detected.
[0017] (Automatic transmission of fire alarm signals) When the control unit detects that the fire extinguisher has been removed, it transmits a fire notification signal to the disaster prevention receiving panel, in the same way as when the transmitter is operated, and outputs a fire alarm.
[0018] (Opening the fire extinguisher door) The fire extinguisher door is an open detector for detecting the opening of the fire extinguisher door; a contact detector that detects human contact with the fire extinguisher door opening / closing handle; is established, The control unit detects that the fire extinguisher door has been opened when both the door opening detected by the open detector and the door contact detected by the contact detector.
[0019] (Fire extinguisher box) The present invention is a fire extinguisher box that is installed in a tunnel, stores a fire extinguisher, and is equipped with an emergency notification device including a transmitter. A control unit is provided that outputs audio and / or visual operation guidance to prompt the user to operate the transmitter when an operation to open the fire extinguisher door is detected without the operation of the transmitter being detected.
[0020] (Automatic transmission of fire alarm signals) When the control unit detects that the fire extinguisher has been removed, it transmits a fire alarm signal to the disaster prevention receiving panel in the same manner as when the transmitter is operated, thereby outputting a fire alarm.
[0021] (Opening the fire extinguisher door) The fire extinguisher door is an open detector for detecting the opening of the fire extinguisher door; a contact detector that detects human contact with the fire extinguisher door opening / closing handle; is established, The control unit detects that the fire extinguisher door has been opened when both the door opening detected by the open detector and the door contact detected by the contact detector. [Effects of the Invention]
[0022] (Effect of Fire Hydrant Device 1) The present invention is a fire hydrant device that is installed in a tunnel and includes at least a fire hydrant device including a fire hose with a nozzle and an emergency notification device including a transmitter, and is provided with a control unit that outputs audio and / or visual operation guidance urging the user to operate the transmitter when an operation to open the hydrant door is detected without the operation of the transmitter being detected.Therefore, a road user who attempts to open the hydrant door and use the hydrant will operate the transmitter in response to the output of audio and / or visual operation guidance urging the user to operate the transmitter, and by ensuring that road users operate the transmitter, the road administrator will be aware of the occurrence of a fire and be able to take appropriate and prompt action.
[0023] (Effect of automatic transmission of fire alarm signals) In addition, when the control unit detects the operation of a specific fire hydrant device following the opening of the hydrant door, it sends a fire notification signal to the disaster prevention receiving panel to output a fire alarm, just as if the transmitter had been operated. Therefore, if the road user does not operate the transmitter even after the fire hydrant device outputs audio and / or visual instructions urging them to operate the transmitter, when the fire hydrant device detects the operation of a specific fire hydrant device following the opening of the hydrant door, the fire hydrant device will determine that a fire has occurred and forcibly and automatically transmit a fire notification signal, so that a fire alarm will be output from the disaster prevention receiving panel even if the transmitter is not operated, allowing the road administrator to be sure that a fire has occurred and to take prompt and appropriate action. In addition, it is possible to appropriately perform the coordinated operation of other emergency equipment in response to the fire alarm, such as an electronic indicator installed at the entrance of a tunnel to indicate that entry into the tunnel is prohibited.
[0024] (Effects of operating prescribed fire hydrant equipment) Furthermore, the operation of a specified fire hydrant device following the opening of the hydrant door is the operation of removing the nozzle, which is an operation that road users would likely perform without operating the transmitter.Therefore, based on the operation of removing the nozzle following the opening of the hydrant door, it can be estimated with high certainty that a fire has occurred in the tunnel that requires firefighting activities using a fire hydrant, making it possible to forcibly and automatically send a fire notification signal.
[0025] (Effect of detecting the opening of the fire hydrant door) In addition, the fire hydrant door is provided with an open detector that detects the opening of the hydrant door and a contact detector that detects human contact with the opening / closing handle of the hydrant door, and the control unit detects that the fire hydrant door has been opened when both the open detector detects that the door is open and the contact detector detects that the door has been contacted.Therefore, even if the fire hydrant door is unexpectedly opened due to vibration or the like, this will not be detected as an open operation of the fire hydrant door, making it possible to reliably prevent the erroneous transmission of a fire notification signal due to the unexpected opening of the fire hydrant door.
[0026] (Effect of Fire Hydrant Device 2) The present invention is a fire hydrant device that is installed in a tunnel and is equipped with a fire hydrant device including a fire hose with a nozzle, a fire extinguisher, and an emergency notification device including a transmitter, and is provided with a control unit that outputs audio and / or visual operation guidance urging the user to operate the transmitter when an operation to open the fire extinguisher door is detected without the operation of the transmitter being detected.Therefore, a road user who attempts to open the fire extinguisher door and remove the fire extinguisher will operate the transmitter in response to the output of audio and / or visual operation guidance urging the user to operate the transmitter, and by ensuring that road users operate the transmitter, the road administrator will be aware of the occurrence of a fire and be able to take appropriate and prompt action.
[0027] (Effect of automatic transmission of fire alarm signals) In addition, when the control unit detects the removal of the fire extinguisher, it sends a fire notification signal to the disaster prevention receiving panel to output a fire alarm, just as if the transmitter had been operated. Therefore, if the road user does not operate the transmitter even after audio and / or visual instructions urging them to operate the transmitter are output, when the detection of the opening of the fire extinguisher door is followed by the detection of the removal of the fire extinguisher, it determines that a fire has occurred and forcibly and automatically sends a fire notification signal. This means that the disaster prevention receiving panel will output a fire alarm even if the transmitter is not operated, and the road administrator will be sure to be aware of the fire and be able to take prompt and appropriate action. In addition, it will be possible to appropriately perform the coordinated operation of other emergency equipment in response to the fire alarm, such as an electronic indicator installed at the entrance of a tunnel to indicate that entry into the tunnel is prohibited.
[0028] (Effect of opening the fire extinguisher door) In addition, the fire extinguisher door is provided with an open detector that detects the opening of the fire extinguisher door and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door, and the control unit detects that the fire extinguisher door has been opened when both the open detector detects the door being opened and the contact detector detects door contact.Therefore, even if the fire extinguisher door is unexpectedly opened due to vibration or the like, this will not be detected as an opening operation of the fire extinguisher door, making it possible to reliably prevent the erroneous transmission of a fire alarm signal due to the unexpected opening of the fire extinguisher door.
[0029] (Fire extinguisher box effect) The present invention is a fire extinguisher box that is installed in a tunnel, stores a fire extinguisher, and is equipped with an emergency notification device including a transmitter.If an operation to open the fire extinguisher door is detected without detecting operation of the transmitter, a control unit is provided that outputs audio and / or visual operation guidance urging the user to operate the transmitter.Therefore, in the case of the fire extinguisher box, a road user who attempts to open the fire extinguisher door and remove a fire extinguisher will operate the transmitter in response to the output of audio and / or visual operation guidance urging the user to operate the transmitter.By ensuring that road users operate the transmitter, the road administrator will be aware of the occurrence of a fire and be able to take appropriate and prompt action.
[0030] (Effect of automatic transmission of fire alarm signals) In addition, when the control unit detects the removal of a fire extinguisher, it sends a fire notification signal to the disaster prevention receiving panel to output a fire alarm, just as if the transmitter had been operated. Therefore, even if a road user does not operate the transmitter despite audio and / or visual instructions urging them to operate the transmitter, if the fire extinguisher box detects the opening of the fire extinguisher door and then the removal of the fire extinguisher, it determines that a fire has occurred and automatically sends a fire notification signal. This ensures that the disaster prevention receiving panel outputs a fire alarm even if the transmitter is not operated, allowing the road administrator to be sure that a fire has occurred and take prompt and appropriate action. In addition, it also enables the appropriate coordination of other emergency equipment in response to fire alarms, such as the use of electronic indicators installed at tunnel entrances to display a no-entry sign prohibiting entry into tunnels.
[0031] (Effect of opening the fire extinguisher door) In addition, the fire extinguisher door is provided with an open detector that detects the opening of the fire extinguisher door and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door, and the control unit detects that the fire extinguisher door has been opened when both the open detector detects the door being opened and the contact detector detects door contact.Therefore, even if the fire extinguisher door of the fire extinguisher box is unexpectedly opened due to vibration or the like, it will not be detected as an open operation of the fire extinguisher door, making it possible to reliably prevent the erroneous transmission of a fire alarm signal due to the unexpected opening of the fire extinguisher door.

[0033] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following preferred embodiments.
[0034] [Basic concept of the embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which a fire hydrant device and a fire extinguisher are arranged in a housing.
[0035] Here, a "fire hydrant device" is a type of emergency equipment that is installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is configured to house or contain fire hydrant equipment such as fire hoses, emergency reporting equipment such as red indicator lights and transmitters on the reporting device door, and a fire extinguisher.
[0036] In addition, a "transmitter" is equipped with a push button switch, and when a road user operates the push button switch, a fire notification signal is sent to a disaster prevention receiving panel installed in the tunnel electrical room, etc., which then outputs a fire alarm.
[0037] The "fire hydrant device" of the embodiment is provided with a "control unit" that outputs audio and / or visual operation guidance to prompt the user to operate the transmitter when an operation to open the fire hydrant door is detected without the operation of the transmitter being detected.
[0038] Therefore, road users who attempt to open the hydrant door and use the hydrant without operating the transmitter will operate the transmitter after receiving audio and / or visual instructions urging them to operate the transmitter.By ensuring that road users operate the transmitter, road managers will be aware of the occurrence of a fire and will be able to respond appropriately and quickly.
[0039] In addition, when the "control unit" detects operation of a specified fire hydrant device following the opening of the fire hydrant door, it sends a fire notification signal to the disaster prevention receiving panel, in the same way as when the transmitter is operated, and outputs a fire alarm.
[0040] Therefore, even if the fire hydrant device outputs audio and / or visual instructions urging the road user to operate the transmitter, if the road user does not operate the transmitter, when it detects the opening of the fire hydrant door followed by the operation of a specified fire hydrant device, the fire hydrant device will determine that a fire has occurred and forcibly and automatically send a fire notification signal, so that a fire alarm will be output from the disaster prevention receiving panel even if the transmitter is not operated, ensuring that the road administrator is aware of the fire and can take prompt and appropriate action.In addition to receiving fire signals from fire detectors installed along the length of the tunnel at intervals of 25 or 50 meters, the disaster prevention receiving panel will also receive fire notification signals from the fire hydrant device even if the transmitter is not operated, making it possible to appropriately link other emergency equipment, such as using electronic indicators installed at the tunnel entrance to display a no-entry sign.
[0041] Here, the "operation of a specific fire hydrant device following the opening operation of the fire hydrant door" detected by the control unit is arbitrary, but may be, for example, "the operation of removing the nozzle."
[0042] In addition, in this embodiment, the fire hydrant door is provided with an open detector that detects the opening of the fire hydrant door and a contact detector that detects human contact with the opening / closing handle of the fire hydrant door, and the control unit detects a "fire hydrant door opening operation" when both the door opening by the open detector and door contact by the contact detector are detected.
[0043] Therefore, even if the fire hydrant door is unexpectedly opened due to vibration or the like, if no human contact is detected, it will not be detected as an opening operation of the fire hydrant door, and only the opening operation by a road user will be reliably detected and a fire alarm signal will be transmitted, making it possible to reliably prevent the erroneous transmission of a fire alarm signal due to the unexpected opening of the fire hydrant door when no human contact is detected.
[0044] Here, the "open detector" is a detector that activates when the hydrant door is opened, and the structure and type of the detector are arbitrary, but for example, an open detection switch such as a limit switch that turns on when the hydrant door is open is used. Also, the "contact detector" is a detector that activates when a human hand touches the opening / closing handle of the hydrant door, and the structure and type of the detector are arbitrary, but for example, a touch switch that detects changes in pressure or capacitance when a human hand touches it and outputs a contact detection signal is used.
[0045] In addition, the "control unit" of another type of fire hydrant device outputs audio and / or visual guidance urging the user to operate the transmitter when an operation to open the fire extinguisher door is detected without detecting the operation of the transmitter. Therefore, a road user who attempts to open the fire extinguisher door and take out the fire extinguisher without operating the transmitter will operate the transmitter in response to the output of audio and / or visual guidance urging the user to operate the transmitter, ensuring that the road user operates the transmitter reliably, enabling the road administrator to become aware of the occurrence of a fire and take appropriate and prompt action.
[0046] Furthermore, when the "controller" detects the removal of a fire extinguisher, it sends a fire alarm signal to the disaster prevention receiving panel, causing a fire alarm to be issued, just as if the transmitter had been operated. Therefore, if a road user does not operate the transmitter despite receiving audio and / or visual instructions urging them to operate the transmitter based on the detection of the fire extinguisher door being opened, the system automatically and automatically determines that a fire has occurred and issues a fire alarm signal, even if the transmitter is not operated. This ensures that road administrators are aware of the fire and can take prompt and appropriate action. Furthermore, the system also enables the appropriate coordination of other emergency equipment in response to the fire alarm, such as the use of electronic indicators at tunnel entrances to warn against entering the tunnel.
[0047] In addition, the fire extinguisher door is provided with an open detector that detects the opening of the fire extinguisher door and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door, and the control unit detects a "fire extinguisher door opening operation" when both the open detector detects the door being opened and the contact detector detects the door being contacted.
[0048] Therefore, even if the fire extinguisher door is unexpectedly opened due to vibration or the like, if no human contact is detected, it will not be detected as an opening operation of the fire extinguisher door, and only the opening operation by a road user will be reliably detected and a fire alarm signal will be transmitted, making it possible to reliably prevent the erroneous transmission of a fire alarm signal due to the unexpected opening of a fire hydrant door where no human contact is detected.
[0049] In the embodiment of the fire extinguisher box, as in the case of the other form of fire hydrant device described above, the "control unit" outputs audio and / or visual operation guidance urging the operation of the transmitter when it detects an operation to open the fire extinguisher door without detecting operation of the transmitter, and also, when it detects the removal of the fire extinguisher, it sends a constant fire alarm signal to the disaster prevention receiving panel to output a fire alarm, just as if the transmitter had been operated.
[0050] Specific embodiments will be described below. The specific embodiments shown below are for "outputting audio and visual operation guidance to prompt operation of a transmitter when an opening operation of a fire hydrant door or a fire extinguisher door is detected," and will be described for a case where the "open detector" of the fire hydrant door and the fire extinguisher door is an "open detection switch," and the "contact detector" of the fire hydrant door and the fire extinguisher door is a "touch switch" provided on the opening / closing handle (referred to as "door handle" in the "Specific Contents of the Embodiments" below).

[0052] [a. Fire hydrant equipment] The fire hydrant device of this embodiment will be described in more detail below with reference to Fig. 1, which shows an overview of the tunnel emergency equipment, Fig. 2, which shows the fire hydrant device, and Fig. 3, which shows the internal structure of the fire hydrant device from the front with the door open.
[0053] (a1. Overview of tunnel emergency equipment) An overview of the tunnel emergency equipment will be explained below. As shown in Figure 1, the tunnel emergency equipment is configured such that a distribution cable 14 extending from a disaster prevention receiving panel 12 installed in an electrical room or the like of the tunnel facility is connected in stages to, for example, four fire hydrant devices 10 (10-1)-10 (10-4) installed in each longitudinal unit section within the tunnel.
[0054] Here, among the fire hydrant devices 10 (10-1) to 10 (10-4), the fire hydrant device 10 (10-1) connected to the disaster prevention receiving panel 12 at the position closest to the wiring connection becomes the "first stage," and the fire hydrant device 10 (10-4) connected to the farthest position becomes the "final stage."
[0055] The wiring cables 14 include high-voltage wiring cables intended for commercial AC power supplies and low-voltage wiring cables intended for specified DC voltage power supplies, and the low-voltage wiring cables include those consisting of one or more signal lines and a common line.
[0056] (a2. Configuration of fire hydrant equipment) The configuration of the fire hydrant device 10 (10-1) shown in Figure 1 will be described in more detail. The same applies to the fire hydrant devices 10 (10-2) to (10-4). As shown in Figure 2, the fire hydrant device 10 (10-1) has a structure divided into a housing 10a whose interior serves as a fire hydrant storage section and a housing 10b whose interior serves as a fire extinguisher storage section, and decorative frames 11a and 11b are attached to the front of the housings 10a and 10b.
[0057] The door opening of the decorative frame 11a of the housing 10a is divided into upper and lower halves, and a forward-tilting fire hydrant door 15 that opens downward on a hinge is installed at the lower part of the door opening, and a maintenance door 16 that opens upward on a hinge is installed at the upper part of the door opening, and inside this is a fire hydrant storage section that stores fire hoses and valves including a fire hydrant valve as fire hydrant equipment. Fire hydrant door 15 is provided with a door handle 1510, and when a road user puts their hand into door handle 1510 and pulls it toward them, the lock is released and the fire hydrant door 15 can be opened.
[0058] A fire extinguisher door 18 that opens sideways to the left on a hinge is provided on the left side of the door opening in the decorative frame 11b of the housing 10b, and the fire extinguisher storage section inside can store, for example, two fire extinguishers. A door handle 1810 is provided on the fire extinguisher door 18, and when a road user puts their hand into the door handle 1810 and pulls it toward themselves, the lock is released and the fire extinguisher door 18 can be opened. In addition, a viewing window 1820 is provided on the bottom of the fire extinguisher door 18, so that the presence or absence of a fire extinguisher can be confirmed from the outside.
[0059] An electrical door 20 that opens sideways to the right on a hinge is provided on the right side of the door opening in the decorative frame 11b. The electrical door 20 is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 26, and a telephone jack is provided inside the housing 10b of the electrical door 20. The red indicator light 22, transmitter 24, answer lamp 26, and telephone jack provided on the electrical door 20 in this way constitute an emergency notification device.
[0060] The red indicator light 22 is always lit, so that the location of the fire hydrant device 10 (10-1) can be seen from a distance. In the event of a fire, when a road user presses the transmitter 24 to turn on the push button switch of the transmitter 24, a fire notification signal (transmission signal) is sent to the disaster prevention receiving panel 12 installed in an electrical room or the like, and a fire alarm is output. In response to this, a response signal is sent from the disaster prevention receiving panel 12 to the fire hydrant device 10 (10-1), causing the red indicator light 22 to flash and the response lamp 26 to light up.
[0061] The transmitter 24 is provided with a guidance display unit 44 surrounding it. The guidance display unit 44 may have any structure and function, but may be, for example, a light-emitting plate member using an LED as a light source, and displays guidance to encourage operation of the transmitter 24 by flashing the light-emitting plate member.
[0062] In addition, a speaker unit 45 is provided below the electrically equipped door 20. The speaker unit 45 outputs a predetermined voice message urging a road user to operate the transmitter 24 when the road user opens the fire hydrant door 15 or the fire extinguisher door 18 without operating the transmitter 24.
[0063] The door handle 1510 of the fire hydrant door 15 is provided with a handle touch switch 38. The handle touch switch 38 detects human contact with the door handle 1510, and may have any configuration, function, or type, but may be, for example, a pressure-sensitive switch that detects pressure applied to the handle when operated by a person and turns on, or a capacitance switch that detects a change in capacitance when a person touches the handle and turns on.
[0064] The door handle 1810 of the fire extinguisher door 18 is also provided with a handle touch switch 42, which, like the handle touch switch 38, detects human contact with the door handle 1810, and may be, for example, a pressure-sensitive switch or a capacitance switch.
[0065] The hydrant door 15 is provided with a hydrant door open detection switch 36 that functions as an open detector. The hydrant door open detection switch 36 is a switch that is activated when the hydrant door 15 is opened, and may have any structure or type, but for example, a limit switch equipped with a switch knob or switch lever that appears and disappears as the door is opened or closed is used. As an example, the hydrant door open detection switch 36 is turned off when the hydrant door 15 is closed, and turned on when the hydrant door 15 is open.
[0066] The fire extinguisher door 18 is also provided with a fire extinguisher door open detection switch 40 that functions as an open detector. The fire extinguisher door open detection switch 40 is a switch that is activated when the fire extinguisher door 18 is opened, and similar to the fire hydrant door open detection switch 36, for example, a limit switch equipped with a switch knob or switch lever that appears and disappears as the door is opened and closed is used. As an example, the fire extinguisher door open detection switch 40 is turned off when the fire extinguisher door 18 is closed, and is turned on when the fire extinguisher door 18 is open.
[0067] (a3. Internal structure of fire hydrant device) The internal structure of the fire hydrant device 10 (10-1) shown in Fig. 1 will be described in detail below. The same applies to the fire hydrant devices 10 (10-2) to (10-4).
[0068] As shown in Figure 3, the interior of the housing 10a that serves as the fire hydrant storage section 17 is divided into a valve storage section 1710 and a hose storage section 1720. A water supply pipe 54 drawn in from the outside is connected to a hydrant 56 in the valve storage section 1710, and the pipe branches downward and is connected to a fire hose 62 via a hydrant valve 58 and an automatic pressure regulating valve 60. The hydrant valve 58 is opened and closed by a hydrant valve opening / closing lever 61. When a road user opens or closes the hydrant valve opening / closing lever 61, the hydrant valve 58 is opened and closed in conjunction with the opening and closing of the lever 61 by a known wire link mechanism, and a pump start interlock switch 34 provided in the operation box is turned on and off. In addition, a pump start switch 32 used by the fire brigade is provided to the upper right of the hydrant 56.
[0069] The hose storage section 1720 is provided with a hose storage frame 66, which stores the fire hose 62 drawn in from below by winding it inward clockwise or counterclockwise, and a nozzle 64 is attached to the tip of the fire hose 62 drawn out through a hose guide (hose outlet) 68, and the nozzle 64 is detachably held in a nozzle holder 65. Also, as mentioned above, a fire hydrant door open detection switch 36 is provided at the position where the fire hydrant door 15 at the left end of the hose storage section 1720 closes.
[0070] The nozzle holder 64 is provided with a nozzle removal detection switch 50. The nozzle removal detection switch 50 is a switch that is activated when a road user removes the nozzle 64 from the nozzle holder 65, and can be of any structure or type, but for example, a limit switch equipped with a switch knob or switch lever that appears and disappears depending on whether the nozzle 64 is attached to or detached from the nozzle holder 65 is used. As an example, the nozzle removal detection switch 50 is turned off when the nozzle 64 is held in the nozzle holder 65, and turns on when the nozzle 64 is removed from the nozzle holder 65.
[0071] The inside of housing 10b (on the fire extinguisher door 18 side) is fire extinguisher storage section 19, in which two fire extinguishers 33 are stored. Fire extinguisher removal detection switches 52 are provided at positions corresponding to the bottom of each of the two fire extinguishers 33 stored in fire extinguisher storage section 19. Fire extinguisher removal detection switch 52 is a switch that is activated when a road user removes a fire extinguisher 33 from fire extinguisher storage section 19, and similar to nozzle removal detection switch 50, for example, a limit switch equipped with a switch knob or switch lever that appears and disappears depending on the removal of fire extinguisher 33 is used. As an example, fire extinguisher removal detection switch 52 is turned off when the fire extinguisher 33 is stored, and turns on when the fire extinguisher 33 is removed.
[0072] Terminal boxes 30 and 31 are installed on the rear surface of the fire extinguisher storage section 19. The red indicator light 22 provided on the electrical door 20 is connected to the terminal box 30 via a wiring cable, and the transmitter 24, answer lamp 26, and telephone jack 28 provided on the electrical door 20 are connected to the terminal box 31 via wiring cables, and further, the pump start switch 32 and pump start interlock switch 34 provided in the valve storage section 1710 are connected via wiring cables.
[0073] A cable rack 69 is installed in the hose storage section 1720 inside the housing 10a. The cable rack 69 is connected to the terminal box 30 through a high-voltage cable drawn in from the outside, and is also connected to the terminal box 31 through a low-voltage cable drawn in from the outside, and is further connected to the terminal box 31 through wiring cables from the pump start switch 32 and the pump start interlock switch 34.
[0074] A control unit 48 is installed below the terminal boxes 30, 31 on the rear surface of the fire extinguisher storage unit 19. The control unit 48 controls the output of operation guidance urging the operation of the transmitter 24 by flashing the guidance display unit 44 and outputting a voice message from the speaker unit 45 when an opening operation of the fire hydrant door 15 is detected without detecting operation of the transmitter 24, or when an opening operation of the fire extinguisher door 18 is detected without detecting operation of the transmitter 24.
[0075] In addition, the control unit 48 controls the transmission of a fire notification signal to the disaster prevention receiving panel in the same way as when the transmitter 24 is operated, when an operation of a specified fire hydrant device, for example, the removal of the nozzle 64, is detected after the opening operation of the fire hydrant door 15 is detected and operation guidance is given to encourage the operation of the transmitter 24, or when an operation of removing the fire extinguisher 33 is detected after the opening operation of the fire extinguisher door 18 is detected and operation guidance is given to encourage the operation of the transmitter 24.
[0076] [b. Control Unit] The control unit provided in the fire hydrant device will be described in more detail below with reference to Figure 4, which is a block diagram showing the functional configuration of the control unit provided in the fire hydrant device, Figures 5 and 6, which are wiring circuit diagrams showing the wiring to the electrical equipment of the fire hydrant device, and Figure 7, which is a flowchart showing the operation guidance control by the control unit.
[0077] (b1. Functional configuration of the control unit) The functional configuration of the control unit 48 will be described in more detail below. As shown in Fig. 4, the control unit 48 is made up of a computer circuit equipped with a CPU, memory, and various input / output ports, and realizes predetermined control functions by executing a control program stored in the memory.
[0078] The control unit 48 is provided with a current detection unit 35, a fire hydrant input unit 70, and a fire extinguisher input unit 72 as input targets for the control unit 48. The control unit 48 is also provided with a guidance display unit 44, a speaker unit 45, and a fire notification signal transmission unit 46 as output targets for the control unit 48.
[0079] The current detection unit 35 detects the presence or absence of a fire notification signal transmitted to the disaster prevention receiving panel 12 in response to operation of the transmitter 24. When the transmitter 24 is operated, a predetermined fire notification signal current i flows in the signal line connecting the transmitter 24 and the disaster prevention receiving panel 12, which is detected by the current detection unit 35 and outputs a transmitter operation detection signal E1 to the control unit 48. Therefore, when the transmitter operation detection signal E1 is not input, i.e., when the fire notification signal current i is not flowing, the control unit 48 can determine that operation of the transmitter 24 has not been detected.
[0080] The hydrant input unit 70 is provided with a hydrant door open detection switch 36, a handle touch switch 38, and a nozzle removal detection switch 50. The hydrant door open detection switch 36 detects the opening of the hydrant door 15 and outputs a door open detection signal E2. The handle touch switch 38 detects contact when a road user opens the door handle 1510 of the hydrant door 15 and outputs a contact detection signal E3. The nozzle removal detection switch 50 detects the removal operation of the nozzle 64 by the road user and outputs a nozzle removal detection signal E4.
[0081] The fire extinguisher input unit 72 is provided with a fire extinguisher door open detection switch 40, a handle touch switch 42, and a fire extinguisher removal detection switch 52. The fire extinguisher door open detection switch 40 detects the opening of the fire extinguisher door 18 and outputs a door open detection signal E5. The handle touch switch 42 detects contact when a road user opens the door handle 1810 of the fire extinguisher door 18 and outputs a contact detection signal E6. The fire extinguisher removal detection switch 52 detects the removal operation of the fire extinguisher 33 by the road user and outputs a fire extinguisher removal detection signal E7.
[0082] The guidance display unit 44 is provided in the transmitter 24 shown in Figures 2 and 3, and is driven to flash, for example, in response to a control signal from the control unit 48. The speaker unit 45 outputs a predetermined voice message urging the user to operate the transmitter in response to an audio signal from the control unit 48. This voice message is arbitrary, but for example, it may repeatedly output "Beep beep, beep, transmitter not operated, please operate the transmitter to report a fire."
[0083] The fire alert signal transmitting unit 46 includes a relay X and its relay contact x1 that are activated by a control signal from the control unit 48. The relay contact x1 is connected in parallel to the switch contact of the transmitter 24. When the relay contact x1 is closed by activation of the relay X, a fire alert signal current i flows in the signal line connecting the disaster prevention receiving panel 12 and the transmitter 24, and a fire alert signal is transmitted to the disaster prevention receiving panel 12 in the same manner as when the transmitter 24 is operated.
[0084] (b2. Hydrant side operation guidance control) A more detailed description will be given of the control of the operation guidance on the hydrant side by the control unit 48. When the control unit 48 detects the input of the door open detection signal E2 from the hydrant door open detection switch 36 and the input of the contact detection signal E3 from the handle touch switch 38, it determines that the fire hydrant door 15 is being opened, and if the input of the transmitter operation detection signal E1 from the current detection unit 35 is not detected at that time, it outputs a control signal to the guidance display unit 44 to drive it to flash, and also drives the speaker unit 45 with an audio signal to output a predetermined audio message, thereby controlling the output of operation guidance that encourages the operation of the transmitter 24.
[0085] In addition, when the control unit 48 detects input of the nozzle removal detection signal E4 from the nozzle removal detection switch 50 while outputting operation guidance urging the operation of the transmitter 24, it activates the relay X of the fire notification signal transmitting unit 46 to close the relay contact x1, and controls the transmission of a fire notification signal to the disaster prevention receiving panel 12.
[0086] (b3. Fire extinguisher operation guidance control) The control of the operation guidance on the fire extinguisher side by the control unit 48 will be described in more detail. When the control unit 48 detects the input of the door open detection signal E5 from the fire extinguisher door open detection switch 40 and the input of the contact detection signal E6 from the handle touch switch 42, it determines that the fire extinguisher door 18 is being opened, and if the input of the transmitter operation detection signal E1 from the current detection unit 35 is not detected at that time, it outputs a control signal to the guidance display unit 44 to cause it to flash, and also drives the speaker unit 45 with an audio signal to output a predetermined audio message, thereby controlling the output of operation guidance encouraging the operation of the transmitter 24.
[0087] In addition, when the control unit 48 detects input of a fire extinguisher removal detection signal E7 from the fire extinguisher removal detection switch 52 while outputting operation guidance urging the operation of the transmitter 24, it activates the relay X of the fire notification signal transmitting unit 46 to close the relay contact x1, and controls the transmission of a fire notification signal to the disaster prevention receiving panel 12.
[0088] (b4. Wiring circuits for electrical equipment) A more detailed description will be given of the wiring circuit of the electrical equipment provided in the electrical door 20 and the valve storage section 1710. In this description, reference will be made to Fig. 5, which is a wiring circuit diagram showing the wiring for the electrical equipment of the first-stage fire hydrant device 10 (10-1), and Fig. 6, which is a wiring circuit diagram showing the wiring for the electrical equipment of the last-stage fire hydrant device 10 (10-4).
[0089] As shown in Figure 5, the telephone line T, telephone common line TC, pump start line HA, manual notification line M, manual notification common line MC, response line MF, and response common line FC, which are pulled out from the disaster prevention receiving panel 12 and drawn into the hydrant device housing, are connected to the transmitter 24, response lamp 26, and telephone jack 28 provided on the electrical door of the first stage hydrant device 10 (10-1), and the pump start switch 32 and pump start interlock switch 34 provided in the valve storage section 1710, using the terminal block 74 of the terminal box 31 located inside the hydrant device 10 (10-1) housing.
[0090] Furthermore, the telephone line T, telephone common line TC, pump starting line HA, manual reporting line M, manual reporting common line MC, response line MF, and response common line FC from the first-stage fire hydrant device 10 (10-1) to the second-stage fire hydrant device 10 (10-2) are each connected as crossover lines. This also applies between the second-stage fire hydrant device 10 (10-2) and the third-stage fire hydrant device 10 (10-3), and between the third-stage fire hydrant device 10 (10-3) and the fourth-stage fire hydrant device 10 (10-3), which is the final stage shown in Figure 6. Note that the red indicator light 22 uses the terminal block of the terminal box 30, so its explanation and illustration are omitted.
[0091] Of these electrical devices, the manual reporting line M connected to the transmitter 24, which performs an especially important function in the event of a fire, and the pump starting line HA and manual reporting common line MC connected to the pump starting switch 32 and pump starting interlock switch 34, are monitored for disconnection by connecting a terminating resistor 76 between terminals M1 and MC4, to which the manual reporting line M and manual reporting common line MC are connected, and a terminating resistor 78 between terminals HA1 and MC4, to which the pump starting line HA and manual reporting common line MC are connected, in a terminal block 74, as shown in Fig. 6. Note that disconnection monitoring by the disaster prevention receiving panel 12 sequentially switches and connects the manual reporting line M and manual reporting common line MC, and the pump starting line HA and manual reporting common line MC, to the disconnection monitoring circuit at predetermined intervals, and outputs a predetermined fault alarm.
[0092] As shown in Fig. 5, the transmitter 24 provided on the electric door 20 of the first-stage fire hydrant device 10 (10-1) has two-circuit switch contacts 2410, 2420 with a locking structure, and the switch contact 2410 is connected between the manual report line M and the manual report common line MC via the current detection unit 35 and the terminal block 74. When the transmitter 24 is operated, the switch contact 2410 closes, and a fire report signal current i flows from the manual report line M on the positive side to the manual report common line MC on the negative side, and the fire report signal is sent to the disaster prevention receiving panel 12, and a fire alarm is output.
[0093] The relay contact x1 of the relay X, which is operated by the control unit 48, is connected in parallel with the switch contact 2410 of the transmitter 24. When the relay contact x1 is closed by the operation of the relay X, a fire notification signal current i flows from the manual notification line M to the manual notification common line MC, just as when the switch contact 2410 is closed by operating the transmitter 24, and the fire notification signal is transmitted to the disaster prevention receiving panel 12, and a fire alarm is output.
[0094] Furthermore, the signal line connecting the negative terminal of the switch contact 2410 of the transmitter 24 to the terminal MC4 of the terminal block 74 passes through the current detection unit 35. Therefore, when the transmitter 24 is operated to close the switch contact 2410, the fire notification signal current i flows through the current detection unit 35, and the current detection unit 35 outputs a transmitter operation detection signal E1.
[0095] The response lamp 26 has one end connected to the response line MF via the terminal block 74, and the other end connected to the response common line FC via the switch contact 2420 of the transmitter 24 and the terminal block 74, and lights up when it receives a signal voltage from the response common line FC drawn from the disaster prevention receiving panel 12 when the switch contact 2420 is turned on by operating the transmitter 24.
[0096] The switch contact 3210 of the pump start switch 32 and the switch contact 3410 of the pump start interlock switch 34 are connected in parallel, with one end of the parallel connection connected to the pump start line HA via the terminal block 74, and the other end of the parallel connection connected to the manual report common line MC via the terminal block 74. Therefore, when the switch contact 3210 of the pump start switch 32 or the switch contact 3410 of the pump start interlock switch 34 is closed, a signal current flows from the pump start line HA to the manual report common line MC, and a pump start signal is sent to the disaster prevention receiving panel 12.
[0097] Furthermore, the telephone jack 28 is connected to the telephone line T and the telephone common line TC via a terminal block 74, and an attendant can connect the plug of a telephone they carry to the telephone jack 28 to make a call with the disaster prevention receiving panel 12. The wiring circuit of such electrical equipment is also the same for the final stage fire hydrant device 10 (10-4) shown in Figure 6.
[0098] [c. Control behavior of operation guidance in fire hydrant equipment] A more detailed description will be given of the control operation of the operation guidance in the fire hydrant device by the control unit in Fig. 4. In this description, reference will be made to Fig. 7, which is a flowchart showing the operation guidance control by the control unit in Fig. 4.
[0099] As shown in FIG. 7, the control unit 48 monitors the detection of the opening of the fire hydrant door 15 by the fire hydrant door open detection switch 36 (step S1). If a vehicle fire occurs in a tunnel due to an accident or the like and a road user operates the fire hydrant door 15 to open it, the control unit 48 detects the input of the door open detection signal E2 from the fire hydrant door open detection switch 36 and determines that the fire hydrant door 15 has been detected as open (Yes in step S1).
[0100] At this time, if the road user is not operating the transmitter 24, the transmitter 24 is determined to be off because the transmitter operation detection signal E1 is not output from the current detection unit 35 (Yes in step S2), and the control unit 48 causes the guidance display unit 44 provided corresponding to the transmitter 24 to flash, and outputs a voice message from the speaker unit 45 urging the user to operate the transmitter 24, thereby outputting a guidance display and voice guidance for operating the transmitter (step S3).
[0101] Here, when a road user operates the transmitter 24 in response to the guidance display and guidance voice for transmitter operation, the current detection unit 35 outputs a transmission operation detection signal E1, which causes the control unit 48 to determine that the transmitter 24 is on (No in step S2), and the initial state is restored, thereby stopping the guidance display and guidance voice for transmitter operation.
[0102] In contrast, if a road user removes the nozzle 64 without operating the transmitter 24, the nozzle removal detection switch 50 detects the removal of the nozzle 64, which is a predetermined operation following the opening of the fire hydrant door 15 (Yes in step S4), and the control unit 48 determines that a fire has been confirmed and sends a fire notification signal to the disaster prevention receiving panel 12 by closing the relay contact x1 due to the activation of the relay X of the fire notification signal transmitting unit 46 (step S5), and outputs a fire alarm.
[0103] On the other hand, when the control unit 48 has not determined that the fire hydrant door 15 has been detected as open by the fire hydrant door open detection switch 36 (No in step S1), it monitors the detection of the fire extinguisher door 18 being open by the fire extinguisher door open detection switch 40 (step S6).If a vehicle fire occurs in a tunnel due to an accident or the like and a road user operates the fire extinguisher door 18 to open it, the control unit 48 detects the input of the door open detection signal E2 from the fire extinguisher door open detection switch 40 and determines that the fire extinguisher door 18 has been detected as open (Yes in step S6).
[0104] At this time, if the road user is not operating the transmitter 24, the current detection unit 35 does not output the transmitter operation detection signal E1, thereby determining that the transmitter 24 is off (Yes in step S7), and the control unit 48 causes the guidance display unit 44 provided corresponding to the transmitter 24 to flash, and outputs an audio message from the speaker unit 45 urging the user to operate the transmitter 24, thereby outputting a guidance display and audio guidance for operating the transmitter (step S8).
[0105] Here, when a road user operates the transmitter 24 in response to the guidance display and guidance voice for transmitter operation, the current detection unit 35 outputs a transmission operation detection signal E1, which causes the control unit 48 to determine that the transmitter 24 is on (No in step S7), and the initial state is restored, thereby stopping the guidance display and guidance voice for transmitter operation.
[0106] In contrast, if a road user removes the fire extinguisher 33 without operating the transmitter 24, the fire extinguisher removal detection switch 52 detects the removal of the fire extinguisher 33, which is a predetermined operation following the opening of the fire extinguisher door 18 (Yes in step S9), and determines that a fire has occurred.The fire notification signal transmitting unit 46 activates the relay X to close the relay contact x1, thereby transmitting a fire notification signal to the disaster prevention receiving panel 12 (step S10), and a fire alarm is output.
[0107] [d. Fire extinguisher box] The fire extinguisher box with an operation guidance function will be described in more detail below with reference to Fig. 8 showing the fire extinguisher box, Fig. 9 which is a block diagram showing the functional configuration of the control unit provided in the fire extinguisher box, and Fig. 10 which is a flowchart showing the control operation of the operation guidance by the control unit in Fig. 9.
[0108] (d1: Fire extinguisher box configuration) The configuration of the fire extinguisher box will be described in more detail. The fire extinguisher box 100 of this embodiment corresponds to the configuration of the housing 10b side of the fire hydrant device 10 (10-1) shown in FIG. 2, removed. As shown in FIG. 8, a fire extinguisher door 18 that opens sideways to the left on a hinge is provided on the left side of the door opening in the decorative frame 102 of the housing 101 of the fire extinguisher box 100, and for example, two fire extinguishers can be stored in the fire extinguisher storage section inside. A door handle 1810 is provided on the fire extinguisher door 18, and when a road user reaches into the door handle 1810 and pulls it toward themselves, the lock is released and the fire extinguisher door 18 can be opened. In addition, a viewing window 1820 is provided on the bottom of the fire extinguisher door 18, allowing the presence or absence of a fire extinguisher to be confirmed from the outside.
[0109] An electrical door 20 that opens sideways to the right on a hinge is provided on the right side of the door opening in the decorative frame 11b. The electrical door 20 is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 26, and a telephone jack is provided inside the housing 10b of the electrical door 20. The red indicator light 22, transmitter 24, answer lamp 26, and telephone jack provided on the electrical door 20 in this way constitute an emergency notification device.
[0110] The red indicator light 22 is always lit, so that the location of the fire extinguisher box 100 can be seen from a distance. In the event of a fire, when a road user presses the transmitter 24 to turn on the push button switch of the transmitter 24, a fire notification signal (transmission signal) is sent to the disaster prevention receiving panel 12 installed in an electrical room or the like, and a fire alarm is output, and accordingly a response signal is sent from the disaster prevention receiving panel 12 to the fire extinguisher box 100, causing the red indicator light 22 to flash and the response lamp 26 to light up.
[0111] The transmitter 24 is provided with a guidance display unit 44 surrounding it. The guidance display unit 44 may have any structure and function, but may be, for example, a light-emitting plate member using an LED as a light source, and displays guidance to encourage operation of the transmitter 24 by flashing the light-emitting plate member.
[0112] In addition, a speaker unit 45 is provided below the electrically equipped door 20. The speaker unit 45 outputs a predetermined voice message urging a road user to operate the transmitter 24 when the road user opens the fire hydrant door 15 or the fire extinguisher door 18 without operating the transmitter 24.
[0113] The door handle 1810 of the fire extinguisher door 18 is provided with a handle touch switch 42. The handle touch switch 42 detects human contact with the door handle 1810, and may have any configuration, function, or type, but may be, for example, a pressure-sensitive switch that detects pressure applied to the handle when operated by a person and turns on, or a capacitance switch that detects a change in capacitance when a person touches the handle and turns on.
[0114] The fire extinguisher door 18 is provided with a fire extinguisher door open detection switch 40 that functions as an open detector. The fire extinguisher door open detection switch 40 is a switch that is activated when the fire extinguisher door 18 is opened, and may have any structure or type, but for example, a limit switch equipped with a switch knob or switch lever that appears and disappears as the door is opened or closed is used. As an example, the fire extinguisher door open detection switch 40 is turned off when the fire extinguisher door 18 is closed, and turned on when the fire extinguisher door 18 is open.
[0115] (d2. Functional configuration of the control unit) A more detailed description will be given of the control unit provided in the fire extinguisher box 100. As shown in Fig. 9, the control unit 480 provided in the fire extinguisher box 100 corresponds to the functional configuration of the control unit 48 of the fire hydrant device shown in Fig. 4 excluding the hydrant input unit 70.
[0116] A more detailed description will be given of the functional configuration of control unit 480. As shown in Fig. 9, control unit 480 is made up of a computer circuit equipped with a CPU, memory, and various input / output ports, and realizes predetermined control functions by executing a control program stored in the memory.
[0117] The control unit 480 is provided with a current detection unit 35, a fire extinguisher door open detection switch 40, a handle touch switch 42, and a fire extinguisher removal detection switch 52 as input targets for the control unit 480. The control unit 480 is also provided with a guidance display unit 44, a speaker unit 45, and a fire notification signal transmission unit 46 as output targets for the control unit 480. The configurations and functions of the control unit 480 and its input targets and output targets are the same as those in Fig. 4, and therefore the same reference numerals are used and a description thereof will be omitted.
[0118] (d3. Control behavior of operation guide in fire extinguisher box) The control operation of the operation guidance for the fire extinguisher box by the control unit 480 in Fig. 9 will be described in more detail. As shown in Fig. 10, the control unit 480 monitors the detection of opening of the fire extinguisher door 18 by the fire extinguisher door open detection switch 40 (step S11), and if a road user operates to open the fire extinguisher door 18 in the event of a vehicle fire occurring due to an accident or the like in a tunnel, the control unit 480 detects the input of the door open detection signal E5 from the fire extinguisher door open detection switch 40 and determines that the fire extinguisher door 18 is open (Yes in step S11).
[0119] At this time, if the road user is not operating the transmitter 24, the transmitter 24 is determined to be off because the transmitter operation detection signal E1 is not output from the current detection unit 35 (Yes in step S12), and the control unit 48 causes the guidance display unit 44 provided corresponding to the transmitter 24 to flash and outputs an audio message from the speaker unit 45 urging the user to operate the transmitter 24, thereby outputting a guidance display and audio guidance for operating the transmitter (step S13).
[0120] Here, when a road user operates the transmitter 24 in response to the guidance display and guidance voice for transmitter operation, the current detection unit 35 outputs a transmission operation detection signal E1, which causes the control unit 48 to determine that the transmitter 24 is on (No in step S12), and the initial state is restored, thereby stopping the guidance display and guidance voice for transmitter operation.
[0121] In contrast, if a road user removes the fire extinguisher 33 without operating the transmitter 24, the fire extinguisher removal detection switch 52 detects the removal of the fire extinguisher 33, which is a predetermined operation following the opening of the fire extinguisher door 18 (Yes in step S14), and determines that a fire has occurred.The fire notification signal transmitting unit 46 activates the relay X to close the relay contact x1, thereby transmitting a fire notification signal to the disaster prevention receiving panel 12 (step S15), and a fire alarm is output.
[0122] [e. Modifications of the present invention] Modifications of the fire hydrant device and fire extinguisher box according to the present invention will be described in more detail. In addition to the above-described embodiment, the fire hydrant device and fire extinguisher box according to the present invention also include the following modifications.
[0123] (Transmission circuits for electrical equipment) The electrical equipment installed in the electrically equipped door in the above embodiment is, for example, a P-type (Proprietary-type) transmission circuit that transmits and receives signals on a signal line basis drawn from the disaster prevention monitoring panel, but it may also be an R-type (Record-type) transmission circuit in which a unique address is set for each electrically equipped door (emergency notification device), and an upstream signal indicating device control with the specified address is transmitted from the transmission unit installed in the electrically equipped door to the transmission unit of the disaster prevention receiving panel, and a downstream signal including the address and detection information is transmitted from the transmission unit of the disaster prevention receiving panel to the transmission unit of the electrically equipped door.
[0124] (Announcement of transmitter operation instructions) In the above embodiment, the guidance display unit 44 and the speaker unit 45 that outputs a voice message are provided to provide guidance to prompt the user to operate the transmitter, but the configuration may be such that only one of them is provided.
[0125] (Emergency opening of fire hydrant door or fire extinguisher door) In the above embodiment, when switch outputs are obtained from both the fire hydrant door or fire extinguisher door open detection switch and the handle touch switch, an open operation is detected and operation guidance is given to prompt operation of the transmitter. However, when switch output is obtained only from the fire hydrant door or fire extinguisher door open detection switch, this indicates that the fire hydrant door or fire extinguisher door has been unexpectedly opened due to vibration or the like, and in this case, the configuration may be such that a predetermined warning signal is sent from the control unit to the disaster prevention receiving panel to output a warning alarm.
[0126] (Inspection work) Furthermore, fire hydrant devices and fire extinguisher boxes are inspected periodically, and during such inspections, an inspector can open the hydrant door or fire extinguisher door without operating the transmitter, thereby confirming that the operation guidance prompting the operator to operate the transmitter is being issued normally. Furthermore, if an inspection switch is provided on the inside of an electrical door or the like, and the inspection mode is set by operating the inspection switch, the system may be configured such that the operation guidance prompting the operator to operate the transmitter is not issued even if the inspector opens the hydrant door or fire extinguisher door for inspection.
[0127] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages thereof, and for example, in addition to fire hydrant devices and fire extinguisher boxes, the present invention can be applied to equipment that has an emergency notification device and a door, and that allows access inside the door to perform various disaster prevention operations in the event of a fire or other disaster, and in this case, for example, the emergency notification device may be arranged near the equipment main body as a separate unit from the equipment main body that has the door. Furthermore, the present invention is not limited by the numerical values shown in the above embodiments. [Explanation of symbols]
