Fire hydrant system and fire extinguisher box

Abstract

Even if the fire alarm is not activated and firefighting efforts are carried out using fire hydrants or fire extinguishers, this system ensures the proper operation and management of emergency equipment in the event of a fire. [Solution] If the control unit 48 detects that the fire hydrant door 15 has been opened without any operation of the transmitter 24 by a road user, it outputs a voice prompting the user to operate the transmitter 24 from the speaker unit 45 and causes the guidance display unit 44 of the transmitter 24 to flash. If the control unit 48 detects that an operation of a predetermined fire hydrant device following the opening of the fire hydrant door 15 has been performed, for example, the operation of removing the nozzle of the fire hose, without any operation of the transmitter 24, the control unit 48 determines that a fire has been confirmed and automatically and forcibly transmits a fire alarm signal to the disaster prevention receiving panel, just as if the transmitter 24 had been operated, to output a fire alarm.

Description

Technical Field

[0001] The present invention relates to a fire hydrant device installed in a tunnel for storing a fire hose, a fire extinguisher, etc., and a fire extinguisher box installed in a tunnel for storing a fire extinguisher.

Background Art

[0002] Conventionally, a fire hydrant device has been installed in a tunnel such as a highway or an expressway as an emergency facility in the tunnel. The fire hydrant device stores a fire hose with a nozzle attached to its tip and valves including a fire hydrant valve in a fire hydrant storage section of a housing equipped with a fire hydrant door, and also stores, for example, two fire extinguishers in a fire extinguisher storage section equipped with a fire extinguisher door. In addition, the fire hydrant device is generally installed by recessing and embedding the tunnel wall surface at intervals of, for example, 50 meters in the longitudinal direction of the tunnel.

[0003] In addition, the fire hydrant device is provided with an emergency reporting device. The emergency reporting device is provided with a red indicator light, a transmitter, a response lamp, and a telephone jack on a reporting device door disposed between the fire hydrant storage section and the fire extinguisher storage section.

[0004] The red indicator light is always on so that the installation location of the fire hydrant device can be confirmed from a distance. When a fire breaks out and the transmitter is pressed to turn on the push button switch, a fire alarm signal is transmitted to a disaster prevention receiving board installed in an electric room or the like, and a fire alarm is output. The disaster prevention receiving board that has output the fire alarm transmits a response signal to the emergency reporting device, causing the red indicator light to blink and the response lamp to light, enabling confirmation that the fire alarm signal has been received on the disaster prevention receiving board side (Patent Document 1).

[0005] Furthermore, since road users are generally unfamiliar with operating fire hydrant systems, when a road user opens the fire hydrant door, they can see instructions on how to operate the fire hydrant system, illustrated with pictures and text. However, in urgent situations such as a fire, it may be difficult to operate the fire hydrant system while reading the instructions. Therefore, fire hydrant systems equipped with a function to guide users on how to operate the fire hydrant system through displays and audio have been proposed (Patent Documents 2, 3). [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2002-102380 [Patent Document 2] Japanese Patent Publication No. 2003-310785 [Patent Document 3] Japanese Patent Publication No. 2019-118423 [Overview of the project] [Problems that the invention aims to solve]

[0007] By the way, if a vehicle fire occurs inside a tunnel due to an accident or other reason, 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 urgent situations such as a fire, it is conceivable that some road users may use fire hydrants or fire extinguishers to extinguish the fire without operating the transmitter to report the fire. If the transmitter is not operated, the fire alarm will not be issued by the disaster prevention receiving panel, and the road administrator will not be aware of the fire. Furthermore, the disaster prevention receiving panel is designed to activate other emergency equipment, such as displaying a no-entry sign on an alarm board installed at the tunnel entrance, when both a fire signal from a fire detector installed at 25-meter or 50-meter intervals along the length of the tunnel and a fire alarm signal from a transmitter are received. However, if the transmitter is not operated, the activation of other emergency equipment will not occur, which could seriously hinder operational management in the event of a fire.

[0009] Furthermore, the operating instructions provided by conventional fire hydrant systems guide users through the procedure of opening the forward-sloping door, removing the fire hose nozzle, and opening the fire hydrant valve to discharge water. However, these instructions do not mention the operation of a fire alarm by using a transmitter prior to operating the fire hydrant. This leaves a problem where road users may operate the fire hydrant system and engage in firefighting activities without first using a transmitter to report a fire.

[0010] This problem also applies to fire extinguisher boxes equipped with emergency notification devices, which are installed as emergency equipment in lower-ranked tunnels, categorized by factors such as traffic volume and tunnel length.

[0011] The present invention aims to provide a fire hydrant system and a fire extinguisher box that enable proper operation and management of tunnel emergency equipment in response to a fire, even when firefighting activities are carried out using fire hydrants and fire extinguishers without the activation of the transmitter. [Means for solving the problem]

[0012] (Fire hydrant system 1: Firefighting activities using fire hydrants) The present invention relates to a fire hydrant system installed in a tunnel, comprising at least a fire hydrant device including a fire hose equipped with a nozzle, and an emergency notification device including a transmitter. The system is characterized by having a control unit that outputs voice and / or display guidance prompting the user to operate the transmitter when the opening of a fire hydrant door is detected without the operation of the transmitter being detected.

[0013] (Automatic transmission of fire alarm signal) When the control unit detects the operation of a predetermined fire hydrant device following the opening of a fire hydrant door, it transmits a fire alarm signal to the disaster prevention receiver panel, similar to when a transmitter is operated, and outputs a fire alarm.

[0014] (Operation of designated fire hydrant equipment) Following the operation of opening the fire hydrant door, the next operation of the designated fire hydrant equipment is to extend the nozzle.

[0015] (Detection of fire hydrant door opening operation) The fire hydrant door is An open detector that detects the opening of a fire hydrant door, A contact detector that detects human contact with the opening and closing handle of a fire hydrant door, A system was established, The control unit detects that the fire hydrant door has been opened when both the open detector detects door opening and the contact detector detects door contact.

[0016] (Fire hydrant system 2: Firefighting using fire extinguishers) The present invention relates to a fire hydrant system installed in a tunnel, comprising a fire hydrant device including a fire hose with a nozzle, a fire extinguisher, and an emergency notification device including a transmitter. The system is characterized by having a control unit that outputs voice and / or display guidance prompting the user to operate the transmitter when the opening of the fire extinguisher door is detected without the operation of the transmitter being detected.

[0017] (Automatic transmission of fire alarm signal) When the control unit detects that a fire extinguisher has been removed, it sends a fire alarm signal to the fire prevention receiver panel, just as if the transmitter had been operated, and outputs a fire alarm.

[0018] (Opening the fire extinguisher door) The fire extinguisher door is, An opening detector that detects the opening of the fire extinguisher door, A contact detector that detects a person's contact with the opening / closing handle of the fire extinguisher door, are provided, When both the door opening by the opening detector and the door contact by the contact detector are detected, the control unit detects an opening operation of the fire extinguisher door.

[0019] (Fire extinguisher box) The present invention is a fire extinguisher box installed in a tunnel, storing a fire extinguisher and equipped with an emergency reporting device including a transmitter, characterized in that a control unit is provided which outputs an operation guidance by voice and / or display to prompt the operation of the transmitter when an opening operation of the fire extinguisher door is detected without detecting the operation of the transmitter.

[0020] (Automatic transmission of fire alarm signal) When the removal of the fire extinguisher is detected, the control unit transmits a fire standing alarm signal to the disaster prevention receiving board and outputs a fire alarm in the same manner as when the transmitter is operated.

[0021] (Opening operation of the fire extinguisher door) The fire extinguisher door, An opening detector that detects the opening of the fire extinguisher door, A contact detector that detects a person's contact with the opening / closing handle of the fire extinguisher door, are provided, When both the door opening by the opening detector and the door contact by the contact detector are detected, the control unit detects an opening operation of the fire extinguisher door.

Effect of the invention

[0022] (Effect of the fire hydrant device 1) The present invention relates to a fire hydrant system installed in a tunnel, which includes at least a fire hydrant device including a fire hose with a nozzle and an emergency notification device including a transmitter. The system is equipped with a control unit that outputs voice and / or display guidance prompting the user to operate the transmitter when the opening of the fire hydrant door is detected without the operation of the transmitter being detected. As a result, road users who open the fire hydrant door to use the fire hydrant will operate the transmitter after receiving voice and / or display guidance prompting them to operate the transmitter. This ensures that road users operate the transmitter, allowing road administrators to become aware of a fire and respond appropriately and quickly.

[0023] (Effects of automatic transmission of fire alarm signals) Furthermore, the control unit, upon detecting the opening of a fire hydrant door followed by the operation of a designated fire hydrant device, transmits a fire alarm signal to the disaster prevention receiving panel, similar to the operation of a transmitter, and outputs a fire alarm. Therefore, even if the fire hydrant system outputs voice and / or display guidance prompting the user to operate the transmitter, if the road user does not operate the transmitter, the fire hydrant system will determine that a fire has been confirmed and automatically transmit a fire alarm signal upon detecting the opening of the fire hydrant door followed by the operation of a designated fire hydrant device. This ensures that a fire alarm is output from the disaster prevention receiving panel even if the transmitter is not operated, allowing road administrators to be sure to know about the fire and take swift and appropriate action. In addition, it becomes possible to appropriately coordinate the operation of other emergency equipment in response to the fire alarm, such as displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0024] (Effects of operating designated fire hydrant equipment) Furthermore, since the operation of the fire hydrant equipment following the opening of the fire hydrant door is the operation of extending the nozzle, which road users would likely perform without operating a transmitter, it is possible to estimate with high accuracy that a fire requiring firefighting by fire hydrants has occurred in the tunnel based on the nozzle extension operation that follows the opening of the fire hydrant door, and to transmit a mandatory and automatic fire alarm signal.

[0025] (Effects of detecting the opening operation of the fire hydrant door) Furthermore, the fire hydrant door is equipped with an open detector that detects when the fire hydrant door is open, and a contact detector that detects human contact with the opening / closing handle of the fire hydrant door. The control unit detects that the fire hydrant door has been opened when both the open detector detects the door opening and the contact detector detects contact with the door. Therefore, even if the fire hydrant door opens unexpectedly due to vibration or other reasons, it will not be detected as an opening operation, thus reliably preventing the erroneous transmission of fire alarm signals due to the unexpected opening of the fire hydrant door.

[0026] (Effects of fire hydrant system 2) The present invention relates to a fire hydrant system installed in a tunnel, which includes a fire hose equipped with a nozzle, a fire extinguisher, and an emergency notification device including a transmitter. The system is equipped with a control unit that outputs voice and / or display guidance prompting the user to operate the transmitter when the opening of the fire extinguisher door is detected without the operation of the transmitter being detected. As a result, a road user who opens the fire extinguisher door to take out the fire extinguisher will operate the transmitter after receiving voice and / or display guidance prompting the user to operate the transmitter. This ensures that the transmitter is operated by the road user, allowing the road administrator to become aware of the fire and take appropriate and prompt action.

[0027] (Effects of automatic transmission of fire alarm signals) Furthermore, when the control unit detects that a fire extinguisher has been removed, it sends a fire alarm signal to the disaster prevention receiving panel, just as if the transmitter had been operated, and outputs a fire alarm. Therefore, even if voice and / or display instructions prompting the user to operate the transmitter are output, if the removal of the fire extinguisher is detected following the detection of the fire extinguisher door being opened, the system will determine that a fire has occurred and forcibly and automatically send a fire alarm signal. This ensures that a fire alarm is output on the disaster prevention receiving panel even if the transmitter is not operated, allowing road administrators to be sure that a fire has occurred and to take swift and appropriate action. In addition, it will be possible to properly coordinate the operation of other emergency equipment in response to the fire alarm, for example, by displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0028] (Effects of opening the fire extinguisher door) Furthermore, the fire extinguisher door is equipped with an open detector that detects when the fire extinguisher door is open, and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door. The control unit detects that the fire extinguisher door has been opened only when both the open detector detects the door opening and the contact detector detects contact with the door. Therefore, even if the fire extinguisher door opens unexpectedly due to vibration or other reasons, it will not be detected as an opening operation, thus reliably preventing the false transmission of fire alarm signals due to the unexpected opening of the fire extinguisher door.

[0029] (Effect of fire extinguisher boxes) The present invention relates to a fire extinguisher box installed in a tunnel, which houses a fire extinguisher and is equipped with an emergency notification device including a transmitter. The box is equipped with a control unit that outputs voice and / or display guidance prompting the user to operate the transmitter when the opening of the fire extinguisher door is detected without the operation of the transmitter being detected. As a result, when a road user attempts to open the fire extinguisher door to retrieve a fire extinguisher, they will receive voice and / or display guidance prompting them to operate the transmitter, ensuring that the transmitter is reliably operated by the road user. This allows road administrators to become aware of a fire and respond appropriately and quickly.

[0030] (Effects of automatic transmission of fire alarm signals) Furthermore, when the control unit detects that a fire extinguisher has been removed, it sends a fire alarm signal to the disaster prevention receiving panel, just as if the transmitter had been operated, and outputs a fire alarm. Similarly, if a road user does not operate the transmitter even after voice and / or display instructions prompting operation have been output for the fire extinguisher box, the system will determine that a fire has been confirmed when the fire extinguisher has been removed following the detection of the fire extinguisher door being opened, and will forcibly and automatically send a fire alarm signal. This ensures that a fire alarm is output on the disaster prevention receiving panel even if the transmitter is not operated, allowing road administrators to be sure that a fire has occurred and to take swift and appropriate action. In addition, it will be possible to properly coordinate the operation of other emergency equipment in response to the fire alarm, for example, by displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0031] (Effects of opening the fire extinguisher door) Furthermore, the fire extinguisher door is equipped with an open detector that detects when the fire extinguisher door is open, and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door. The control unit detects that the fire extinguisher door has been opened when both the open detector detects the door opening and the contact detector detects contact with the door. Therefore, even if the fire extinguisher door of the fire extinguisher box is opened unexpectedly due to vibration or other reasons, this will not be detected as an operation to open the fire extinguisher door, thus reliably preventing the false transmission of fire alarm signals due to the unexpected opening of the fire extinguisher door.

[0033] Embodiments of the fire hydrant system and fire extinguisher box according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0034] [Basic Concepts of the Embodiment] First, the basic concept of the embodiment will be explained. The embodiment generally relates to a fire hydrant system in which fire hydrant equipment and fire extinguishers are arranged inside a housing.

[0035] Here, "fire hydrant system" refers to a type of emergency equipment installed in tunnels on expressways and other roads that are designated as fire-fighting areas. It consists of a housing installed in the fire-fighting area containing fire hydrant equipment such as fire hoses, emergency notification equipment such as red indicator lights and transmitters on the notification device door, and fire extinguishers.

[0036] Furthermore, a "transmitter" is equipped with a push-button switch, and when a road user operates the push-button switch, a fire alarm signal is transmitted to a disaster prevention receiving panel installed in the tunnel's electrical room or similar location, causing a fire alarm to be issued.

[0037] The "fire hydrant device" of this embodiment is provided with a "control unit" that outputs voice and / or display guidance prompting the user to operate the transmitter when the operation of opening the fire hydrant door is detected without the operation of the transmitter being detected.

[0038] Therefore, road users who attempt to use a fire hydrant by opening the hydrant door without operating the transmitter will be prompted to operate the transmitter by voice and / or display guidance, ensuring that road users operate the transmitters reliably, which allows road administrators to become aware of a fire and respond appropriately and quickly.

[0039] Furthermore, the "control unit" transmits a fire alarm signal to the disaster prevention receiving panel and outputs a fire alarm, similar to when a transmitter is operated, when it detects the operation of a designated fire hydrant device following the opening of a fire hydrant door.

[0040] Therefore, even if the fire hydrant system outputs voice and / or display instructions prompting the user to operate the transmitter, if the road user does not operate the transmitter, the fire hydrant system will determine that a fire has occurred and automatically transmit a fire alarm signal when it detects the opening of the fire hydrant door followed by the operation of the designated fire hydrant equipment. This ensures that a fire alarm is output from the disaster prevention receiver panel even if the transmitter is not operated, allowing road administrators to be sure to know about the fire and take swift and appropriate action. In addition, the disaster prevention receiver panel receives fire signals from fire detectors installed, for example, at 25-meter or 50-meter intervals along the length of the tunnel, and also receives fire alarm signals from the fire hydrant system even if the transmitter is not operated. This enables the proper coordination of other emergency equipment, such as displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0041] Here, the "operation of a predetermined fire hydrant equipment following the opening of the fire hydrant door" detected by the control unit is arbitrary, but for example, it could be "the operation of removing the nozzle."

[0042] Furthermore, in this embodiment, the fire hydrant door is equipped with an open detector that detects when the fire hydrant door is open, and a contact detector that detects when a person makes contact with the opening / closing handle of the fire hydrant door. The control unit detects "opening operation of the fire hydrant door" when both the open detector detects the door opening and the contact detector detects contact with the door.

[0043] Therefore, even if a fire hydrant door is opened prematurely due to vibration or other reasons, if no human contact is detected, it will not be detected as an operation to open the fire hydrant door. Only an opening operation by a road user will be reliably detected, and a fire alarm signal will be transmitted. This ensures that false transmissions of fire alarm signals due to premature opening of fire hydrant doors without human contact are prevented.

[0044] Here, an "open detector" is a detector that activates when the fire hydrant door is opened. 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 fire hydrant door is opened can be used. A "contact detector" is a detector that activates when a person's hand comes into contact with the opening / closing handle of the fire hydrant door. The structure and type of the detector are arbitrary, but for example, a touch switch that detects changes in pressure or capacitance when a person's hand makes contact and outputs a contact detection signal can be used.

[0045] Furthermore, a different type of fire hydrant system's "control unit" outputs voice and / or display guidance prompting the user to operate the fire extinguisher door if the fire extinguisher door is opened without the operator's activation of the transmitter being detected. As a result, a road user who attempts to open the fire extinguisher door and retrieve the extinguisher without operating the transmitter will be prompted to operate the transmitter by the voice and / or display guidance, ensuring that the transmitter is operated by the road user and enabling road administrators to become aware of a fire and respond appropriately and quickly.

[0046] Furthermore, the "control unit" transmits a fire alarm signal to the disaster prevention receiving panel, similar to when the transmitter is operated, when it detects that a fire extinguisher has been removed, thereby outputting a fire alarm. Therefore, even if voice and / or display guidance prompting the user to operate the transmitter is output based on the detection of the fire extinguisher door being open, if the user does not operate the transmitter, the system will determine that a fire has been confirmed when the operation to remove the fire extinguisher is detected, and a fire alarm signal will be forcibly and automatically transmitted. This ensures that a fire alarm is output from the disaster prevention receiving panel even if the transmitter is not operated, allowing road administrators to be sure that a fire has occurred and to take swift and appropriate action. In addition, it will be possible to appropriately coordinate the operation of other emergency equipment in response to the fire alarm, for example, by displaying a prohibition on tunnel entry on an electronic display installed at the tunnel entrance.

[0047] Furthermore, the fire extinguisher door is equipped with an open detector that detects when the fire extinguisher door is open, and a contact detector that detects human contact with the opening / closing handle of the fire extinguisher door. The control unit detects "opening operation of the fire extinguisher door" when both the open detector detects the door opening and the contact detector detects contact with the door.

[0048] Therefore, even if a fire extinguisher door is opened prematurely due to vibration or other reasons, if no human contact is detected, it will not be detected as an opening operation of the fire extinguisher door. Only opening operations by road users will be reliably detected, and a fire alarm signal will be transmitted. This ensures that false fire alarm signals are not transmitted due to premature opening of fire hydrant doors where no human contact is detected.

[0049] In the fire extinguisher box embodiment, as in the case of the other form of fire hydrant system described above, the "control unit" outputs voice and / or display guidance prompting operation of the transmitter when the opening operation of the fire extinguisher door is detected without the operation of the transmitter being detected, and also transmits a fire alarm signal to the disaster prevention receiver panel and outputs a fire alarm when the removal of the fire extinguisher is detected, just as when the transmitter is operated.

[0050] The following describes a specific embodiment. The specific embodiment described below is one in which "when an opening operation of a fire hydrant door or fire extinguisher door is detected, an operation guidance message is output via voice and display prompting the operation of a transmitter," and the "open detector" of the fire hydrant door and fire extinguisher door is an "open detection switch," and the "contact detector" of the fire hydrant door and fire extinguisher door is a "touch switch" provided on the opening / closing handle (referred to as "door handle" in the following [Specific Details of the Embodiment]).

[0051] [Specific details of the embodiment] We will now explain the fire hydrant system in more detail. The explanation will be divided as follows: a. Fire hydrant system a1. Overview of tunnel emergency equipment a2. Configuration of a fire hydrant system a3. Internal structure of a fire hydrant system b. Control Unit b1. Functional configuration of the control unit b2. Operation guidance control on the fire hydrant side b3. Operation guidance control on the fire extinguisher side b4. Wiring circuits for electrical equipment c. Control operation of the operating guidance in the fire hydrant system d. Fire extinguisher box d1: Fire extinguisher box configuration d2. Functional configuration of the control unit d3. Control operation of the operating guidance in the fire extinguisher box e. Modifications of the present invention

[0052] [a. Fire hydrant system] The fire hydrant system of this embodiment will be described in more detail. In this description, refer to Figure 1, which shows an overview of the tunnel emergency equipment, Figure 2, which shows the fire hydrant system, and Figure 3, which shows the internal structure of the fire hydrant system from the front with the door open.

[0053] (a1. Overview of tunnel emergency equipment) An overview of the tunnel emergency equipment will be described. As shown in Figure 1, the tunnel emergency equipment consists of wiring cables 14 from a disaster prevention receiving panel 12 installed in the electrical room of the tunnel facility, which are connected in stages to, for example, four fire hydrant devices 10(10-1)-10(10-4) installed in each longitudinal unit section of 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 in terms of wiring connection is designated as the "first stage," and the fire hydrant device 10(10-4) connected to the furthest position is designated as the "final stage."

[0055] The wiring cable 14 includes high-voltage wiring cables for commercial AC power and low-voltage wiring cables for a predetermined DC voltage power supply, and the low-voltage wiring cables include those composed of one or more signal lines and a common line.

[0056] (a2. Configuration of fire hydrant system) The configuration of the fire hydrant device 10(10-1) shown in Figure 1 will be explained 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 which houses the fire hydrant and a housing 10b which houses the fire extinguisher, 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 sections. A forward-tilting fire hydrant door 15 that opens downward on a hinge is installed on the lower side of the door opening, and a maintenance door 16 that opens upward on a hinge is installed on the upper side of the door opening. Inside the maintenance door, which is the fire hydrant storage section, fire hydrant equipment including a fire hose and valves including a fire hydrant valve is stored. The fire hydrant door 15 is provided with a door handle 1510, and when a road user puts their hand into the door handle 1510 and pulls it towards them, the lock is released and the fire hydrant door 15 can be opened.

[0058] On the left side of the door opening of the decorative frame 11b of the housing 10b, there is a fire extinguisher door 18 that opens horizontally to the left by a hinge, and the fire extinguisher storage area inside can accommodate, for example, two fire extinguishers. The fire extinguisher door 18 is equipped with a door handle 1810, and when a road user puts their hand into the door handle 1810 and pulls it towards them, the lock is released and the fire extinguisher door 18 can be opened. In addition, a viewing window 1820 is provided on the lower side of the fire extinguisher door 18, allowing the presence or absence of fire extinguishers to be checked from the outside.

[0059] An electrical door 20 is provided on the right side of the door opening of the decorative frame 11b, which opens horizontally to the right by a hinge. The electrical door 20 is equipped with electrical equipment such as a red indicator light 22, a transmitter 24, and a response lamp 26, and a telephone jack is provided inside the housing 10b of the electrical door 20. Thus, the red indicator light 22, transmitter 24, response lamp 26, and telephone jack provided on the electrical door 20 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 and the push button switch on the transmitter 24 is turned on, a fire alarm signal (transmission signal) is sent to the disaster prevention receiving panel 12 installed in the electrical room, etc., and a fire alarm is output. Accordingly, 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 surrounded by a guidance display unit 44. The structure and function of the guidance display unit 44 are arbitrary, but for example, it is a light-emitting plate member with an LED as the light source, and it displays guidance to prompt operation of the transmitter 24 by flashing the light-emitting plate member.

[0062] Furthermore, a speaker unit 45 is provided on the lower side of the electrical door 20. The speaker unit 45 outputs a predetermined voice message prompting the road user to operate the transmitter 24 if they open the fire hydrant door 15 or fire extinguisher door 18 without operating the transmitter 24.

[0063] A handle touch switch 38 is provided on the door handle 1510 of the fire hydrant door 15. The handle touch switch 38 detects human contact with the door handle 1510. Its configuration, function, and type are arbitrary, but for example, a pressure-sensitive switch that turns on when it detects the pressure applied to the handle when a person operates it, or a capacitive switch that turns on when it detects the change in capacitance when a person touches the handle, can be used.

[0064] A handle touch switch 42 is also provided on the door handle 1810 of the fire extinguisher door 18. Similar to the handle touch switch 38, it detects human contact with the door handle 1810, and can be a pressure-sensitive switch or a capacitive switch.

[0065] The fire hydrant door 15 is equipped with a fire hydrant door open detection switch 36, which functions as an open detector. The fire hydrant door open detection switch 36 is a switch that is activated when the fire hydrant door 15 is opened. Its structure and type are arbitrary, but for example, a limit switch equipped with a switch knob or switch lever that extends and retracts with the opening and closing of the door can be used. As an example, the fire hydrant door open detection switch 36 is turned off when the fire hydrant door 15 is closed and turned on when the fire hydrant door 15 is open.

[0066] The fire extinguisher door 18 is also provided with a fire extinguisher door open detection switch 40, which 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, a limit switch equipped with a switch knob or switch lever that extends and retracts in conjunction with the opening and closing of the door is used. For 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.

[0067] (a3. Internal structure of a fire hydrant system) The internal structure of the fire hydrant device 10(10-1) shown in Figure 1 will be explained in detail. The same applies to fire hydrant devices 10(10-2) to (10-4).

[0068] As shown in Figure 3, the interior of the housing 10a, which serves as the fire hydrant storage section 17, is divided into a valve storage section 1710 and a hose storage section 1720. In the valve storage section 1710, a water supply pipe 54 drawn in from the outside is connected to a water tap 56, and also branches downward and is connected to a fire hose 62 via a fire hydrant valve 58 and an automatic pressure regulating valve 60. The fire hydrant valve 58 is opened and closed by a fire hydrant valve opening / closing lever 61. When a road user opens or closes the fire hydrant valve opening / closing lever 61, the fire hydrant valve 58 is opened and closed in conjunction with a known wire linkage mechanism, and a pump activation interlocking switch 34 provided in the operation box is turned on or off. In addition, a pump activation switch 32 used by the fire brigade is provided to the upper right of the water tap 56.

[0069] The hose storage section 1720 is equipped with a hose storage frame 66, which stores the fire extinguishing hose 62 that is pulled in from below by winding it inward clockwise or counterclockwise. A nozzle 64 is attached to the end of the fire extinguishing hose 62 that is pulled out through the hose guide (hose outlet) 68, and the nozzle 64 is detachably held in a nozzle holder 65. 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 is closed.

[0070] The nozzle holder 65 is equipped with a nozzle removal detection switch 50. The nozzle removal detection switch 50 is a switch that operates when a road user removes the nozzle 64 from the nozzle holder 65. Its structure and type are arbitrary, but for example, a limit switch equipped with a switch knob or switch lever that extends and retracts in accordance with the attachment and detachment of the nozzle 64 to the nozzle holder 65 can be used. As an example, the nozzle removal detection switch 50 is 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 interior of the housing 10b (the side with the fire extinguisher door 18) is a fire extinguisher storage compartment 19, which houses two fire extinguishers 33. Fire extinguisher removal detection switches 52 are provided at positions corresponding to the bottom of each of the two fire extinguishers 33 stored in the fire extinguisher storage compartment 19. The fire extinguisher removal detection switches 52 are switches that activate when a road user removes a fire extinguisher 33 from the fire extinguisher storage compartment 19. Similar to the nozzle removal detection switch 50, a limit switch equipped with a switch knob or switch lever that extends or retracts in response to the removal of a fire extinguisher 33 is used. For example, the fire extinguisher removal detection switch 52 is 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 of the fire extinguisher storage section 19. A red indicator light 22 provided on the electrical door 20 is connected to terminal box 30 via a wiring cable, and a transmitter 24, response lamp 26, and telephone jack 28 provided on the electrical door 20 are connected to terminal box 31 via a wiring cable. Furthermore, a pump start switch 32 and a pump start interlock switch 34 provided on the valve storage section 1710 are connected via a wiring cable.

[0073] A cable rack 69 is installed in the hose storage section 1720 inside the enclosure 10a. The cable rack 69 is connected to the terminal box 30 through high-voltage cables brought in from the outside, to the terminal box 31 through low-voltage cables brought in from the outside, and 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 and 31 on the rear of the fire extinguisher storage unit 19. The control unit 48 controls the system to output operation guidance prompting the user to operate the transmitter 24 by flashing the guidance display unit 44 and outputting an audio message from the speaker unit 45 when the operation of the transmitter 24 is detected but the operation of the fire hydrant door 15 is detected but the operation of the fire extinguisher door 18 is detected but the operation of the transmitter 24 is detected.

[0075] Furthermore, the control unit 48, after detecting the opening of the fire hydrant door 15 and providing operation guidance to prompt the operation of the transmitter 24, then detects the operation of a predetermined fire hydrant device, for example, the removal of the nozzle 64, or after detecting the opening of the fire extinguisher door 18 and providing operation guidance to prompt the operation of the transmitter 24, then detects the removal of the fire extinguisher 33, performs control to transmit a fire alarm signal to the disaster prevention receiving panel in the same manner as when the transmitter 24 is operated.

[0076] [b. Control Unit] The control unit installed in the fire hydrant system will be described in more detail. In this description, refer to Figure 4, which is a block diagram showing the functional configuration of the control unit installed in the fire hydrant system; Figures 5 and 6, which are wiring circuit diagrams showing the wiring to the electrical equipment of the fire hydrant system; 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 now be explained in more detail. As shown in Figure 4, the control unit 48 is composed 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. The control unit 48 is also provided with an information display unit 44, a speaker unit 45, and a fire alarm signal transmission unit 46 as output targets.

[0079] The current detection unit 35 detects whether or not a fire alarm signal is transmitted to the disaster prevention receiving panel 12 by the operation of the transmitter 24. When the transmitter 24 is operated, a predetermined fire alarm signal current i flows through the signal line connecting the transmitter 24 and the disaster prevention receiving panel 12. The current detection unit 35 detects this current and outputs a transmitter operation detection signal E1 to the control unit 48. Therefore, if the transmitter operation detection signal E1 is not input, that is, if the fire alarm signal current i is not flowing, the control unit 48 can determine that the operation of the transmitter 24 has not been detected.

[0080] The fire hydrant input section 70 is equipped with a fire hydrant door open detection switch 36, a handle touch switch 38, and a nozzle removal detection switch 50. The fire hydrant door open detection switch 36 detects the opening of the fire hydrant door 15 and outputs a door open detection signal E2. The handle touch switch 38 detects contact made when a road user opens the door handle 1510 of the fire hydrant door 15 and outputs a contact detection signal E3. The nozzle removal detection switch 50 detects the operation of a road user to remove the nozzle 64 and outputs a nozzle removal detection signal E4.

[0081] The fire extinguisher input unit 72 is equipped 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 made 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 operation of a road user to remove the fire extinguisher 33 and outputs a fire extinguisher removal detection signal E7.

[0082] The guidance display unit 44 is located on the transmitter 24 shown in Figures 2 and 3, and is driven to flash, for example, by a control signal from the control unit 48. The speaker unit 45 outputs a predetermined voice message prompting the user to operate the transmitter based on a voice signal from the control unit 48. This voice message is arbitrary, but for example, it repeatedly outputs "Beep beep beep, the transmitter is not being operated. Please operate the transmitter to report the fire."

[0083] The fire alarm signal transmission unit 46 includes a relay X and its relay contact x1, which are operated 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 closes due to the operation of relay X, a fire alarm signal current i flows through the signal line connecting the disaster prevention receiving panel 12 and the transmitter 24, and a fire alarm signal is transmitted to the disaster prevention receiving panel 12, just as when the transmitter 24 is operated.

[0084] (b2. Operation guidance control on the fire hydrant side) The operation guidance control on the fire hydrant side by the control unit 48 will be explained in more detail. When the control unit 48 detects the input of the door open detection signal E2 from the fire hydrant door open detection switch 36 and the contact detection signal E3 from the handle touch switch 38, it determines that the fire hydrant door 15 should be opened. If the input of the transmitter operation detection signal E1 from the current detection unit 35 is not detected at that time, the control unit 48 outputs a control signal to the guidance display unit 44 to make it blink, and also drives the speaker unit 45 with an audio signal to output a predetermined audio message, thereby providing operation guidance to prompt the operation of the transmitter 24.

[0085] Furthermore, when the control unit 48 detects the input of a nozzle removal detection signal E4 from the nozzle removal detection switch 50 while outputting operation guidance prompting the operation of the transmitter 24, it activates the relay X of the fire alarm signal transmission unit 46 to close the relay contact x1 and performs control to transmit a fire alarm signal to the disaster prevention receiving panel 12.

[0086] (b3. Operation guidance control on the fire extinguisher side) The operation guidance control on the fire extinguisher side by the control unit 48 will be explained 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 contact detection signal E6 from the handle touch switch 42, it determines that the fire extinguisher door 18 should be opened. If the input of the transmitter operation detection signal E1 from the current detection unit 35 is not detected at that time, the control unit 48 outputs a control signal to the guidance display unit 44 to make it blink, and also drives the speaker unit 45 with an audio signal to output a predetermined audio message, thereby providing operation guidance prompting the operation of the transmitter 24.

[0087] Furthermore, when the control unit 48 detects the input of a fire extinguisher removal detection signal E7 from the fire extinguisher removal detection switch 52 while outputting operation guidance prompting the operation of the transmitter 24, it activates the relay X of the fire alarm signal transmission unit 46 to close the relay contact x1 and performs control to transmit a fire alarm signal to the disaster prevention receiving panel 12.

[0088] (b4. Wiring circuits for electrical equipment) The wiring circuits for the electrical equipment installed in the electrical door 20 and the valve storage section 1710 will be described in more detail. In this description, refer to Figure 5, a wiring diagram showing the wiring to the electrical equipment of the first stage fire hydrant device 10 (10-1), and Figure 6, a wiring diagram showing the wiring to the electrical equipment of the final stage fire hydrant device 10 (10-4).

[0089] As shown in Figure 5, the transmitter 24, response lamp 26, and telephone jack 28 located on the electrical door of the first-stage fire hydrant device 10 (10-1), and the pump start switch 32 and pump start interlock switch 34 located in the valve storage section 1710 are connected to 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 drawn out from the disaster prevention receiving panel 12 and brought into the housing of the fire hydrant device, using the terminal block 74 of the terminal box 31 located inside the housing of the fire hydrant device 10 (10-1).

[0090] Furthermore, 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 are connected as jumper lines from the first stage fire hydrant device 10(10-1) to the second stage fire hydrant device 10(10-2). This is also the case 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 final stage fire hydrant device 10(10-3) shown in Figure 6. Note that the red indicator light 22 is not shown in the description or illustration because it uses the terminal block of the terminal box 30.

[0091] Of these electrical devices, the manual alarm line M connected to the transmitter 24, which plays a particularly important role in the event of a fire, the pump start line HA connected to the pump start switch 32 and the pump start interlock switch 34, and the manual alarm common line MC are monitored for disconnection in the terminal block 74, as shown in Figure 6. This is done by connecting a terminating resistor 76 between terminals M1 and MC4, to which the manual alarm line M and the manual alarm common line MC are connected, and by connecting a terminating resistor 78 between terminals HA1 and MC4, to which the pump start line HA and the manual alarm common line MC are connected. Disconnection monitoring by the disaster prevention receiver panel 12 sequentially switches the connection between the manual alarm line M and the manual alarm common line MC, and the pump start line HA and the manual alarm common line MC to the disconnection monitoring circuit at predetermined intervals and outputs a predetermined fault alarm.

[0092] As shown in Figure 5, the transmitter 24 installed on the electrical door 20 of the first stage fire hydrant device 10 (10-1) is equipped with two switch contacts 2410 and 2420 that form a locking structure, and the switch contact 2410 is connected between the manual alarm line M and the manual alarm 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 alarm signal current i flows from the positive manual alarm line M to the negative manual alarm common line MC, the fire alarm signal is transmitted to the disaster prevention receiving panel 12, and a fire alarm is output.

[0093] The relay contact x1 of relay X, which is operated by the control unit 48, is connected in parallel with the switch contact 2410 of the transmitter 24. When relay X is activated and relay contact x1 closes, a fire alarm signal current i flows from the manual alarm line M to the manual alarm common line MC, just as when the switch contact 2410 is closed by operation of the transmitter 24. The fire alarm signal is then transmitted to the fire 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 terminal MC4 of the terminal block 74 passes through the current detection unit 35. Therefore, when the transmitter 24 is operated and the switch contact 2410 is closed, the fire alarm 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 terminal block 74, and the other end connected to the response common line FC via switch contact 2420 of the transmitter 24 and terminal block 74. The lamp lights up when the switch contact 2420 is turned ON by operation of the transmitter 24, in response to a signal voltage from the response common line FC drawn from the disaster prevention receiving panel 12.

[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. One end of the parallel connection is connected to the pump start line HA via terminal block 74, and the other end of the parallel connection is connected to the manual notification common line MC via 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 closes, a signal current flows from the pump start line HA to the manual notification common line MC, and a pump start signal is transmitted 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 the terminal block 74, allowing the staff to communicate with the disaster prevention receiving panel 12 by plugging the plug of their portable telephone into the telephone jack 28. The wiring circuit for such electrical equipment is similar for the final stage fire hydrant device 10 (10-4) shown in Figure 6.

[0098] [c. Control operation of the operating guidance in fire hydrant systems] The control operation of the control unit in Figure 4, which provides guidance for operation in the fire hydrant system, will be explained in more detail below. This explanation will refer to Figure 7, a flowchart illustrating the control of the control unit in Figure 4.

[0099] As shown in Figure 7, the control unit 48 monitors the detection of the fire hydrant door 15 being opened by the fire hydrant door open detection switch 36 (step S1). If a vehicle fire occurs in the tunnel due to an accident or the like, and a road user opens the fire hydrant door 15, 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 opened (Yes in step S1).

[0100] At this time, if the road user is not operating the transmitter 24, the current detection unit 35 does not output a transmitter operation detection signal E1, which indicates that the transmitter 24 is off (Yes in step S2). The control unit 48 then drives the guidance display unit 44, which is provided in conjunction with the transmitter 24, to blink, and outputs a voice message from the speaker unit 45 prompting the user to operate the transmitter 24, thereby providing guidance display and voice guidance for transmitter operation (step S3).

[0101] Here, when a road user operates the transmitter 24 after receiving the transmitter operation guidance display and voice guidance, the current detection unit 35 outputs a transmitter operation detection signal E1, which allows the control unit 48 to determine that the transmitter 24 is ON (No. in step S2), and the system returns to its initial state, stopping the transmitter operation guidance display and voice guidance.

[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). The control unit 48 determines that a fire has occurred and, by closing the relay contact x1 due to the operation of relay X of the fire alarm signal transmission unit 46, transmits a fire alarm signal to the disaster prevention receiving panel 12 (step S5), and outputs a fire alarm.

[0103] On the other hand, if the control unit 48 has not determined that the fire hydrant door 15 has been opened by the fire hydrant door open detection switch 36 (No in step S1), it monitors the detection of the fire extinguisher door 18 being opened by the fire extinguisher door open detection switch 40 (step S6). If a vehicle fire occurs in the tunnel due to an accident or the like, and a road user opens the fire extinguisher door 18, 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 opened (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 a transmitter operation detection signal E1, which indicates that the transmitter 24 is off (Yes in step S7). The control unit 48 then drives the guidance display unit 44, which is provided in conjunction with the transmitter 24, to blink and outputs an audio message from the speaker unit 45 prompting the user to operate the transmitter 24, thereby providing guidance display and audio guidance for transmitter operation (step S8).

[0105] Here, when a road user operates the transmitter 24 after receiving the transmitter operation guidance display and voice guidance, the current detection unit 35 outputs a transmitter operation detection signal E1, which allows the control unit 48 to determine that the transmitter 24 is ON (No. in step S7), and the system returns to its initial state, stopping the transmitter operation guidance display and voice guidance.

[0106] In contrast, if a road user takes out 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). The system determines that a fire has occurred and closes the relay contact x1 by activating the relay X of the fire alarm signal transmission unit 46, thereby sending a fire alarm signal to the disaster prevention receiving panel 12 (step S10) and outputting a fire alarm.

[0107] [d. Fire extinguisher box] A fire extinguisher box equipped with an operation guidance function will be described in more detail. In this description, refer to Figure 8, which shows the fire extinguisher box; Figure 9, which is a block diagram showing the functional configuration of the control unit installed in the fire extinguisher box; and Figure 10, which is a flowchart showing the control operation of the operation guidance by the control unit in Figure 9.

[0108] (d1: Fire extinguisher box configuration) The configuration of the fire extinguisher box will now be explained in more detail. The fire extinguisher box 100 of this embodiment corresponds to the configuration obtained by removing the housing 10b side of the fire hydrant device 10(10-1) shown in Figure 2. As shown in Figure 8, a fire extinguisher door 18 that opens horizontally to the left by a hinge is provided on the left side of the door opening of the decorative frame 102 of the housing 101 of the fire extinguisher box 100, and two fire extinguishers can be stored inside the fire extinguisher storage section. The fire extinguisher door 18 is provided with a door handle 1810, and when a road user puts their hand into the door handle 1810 and pulls it towards them, the lock is released and the fire extinguisher door 18 can be opened. In addition, a viewing window 1820 is provided on the lower side of the fire extinguisher door 18, making it possible to check from the outside whether there are fire extinguishers or not.

[0109] An electrical door 20 is provided on the right side of the door opening of the decorative frame 11b, which opens horizontally to the right by a hinge. The electrical door 20 is equipped with electrical equipment such as a red indicator light 22, a transmitter 24, and a response lamp 26, and a telephone jack is provided inside the housing 10b of the electrical door 20. Thus, the red indicator light 22, transmitter 24, response lamp 26, and telephone jack provided on the electrical door 20 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 and the push button switch on the transmitter 24 is turned on, a fire alarm signal (transmission signal) is sent to the disaster prevention receiving panel 12 installed in the electrical room, etc., and a fire alarm is output. In response, a response signal is sent from the disaster prevention receiving panel 12 to the fire extinguisher box 100, the red indicator light 22 flashes and the response lamp 26 lights up.

[0111] The transmitter 24 is surrounded by a guidance display unit 44. The structure and function of the guidance display unit 44 are arbitrary, but for example, it is a light-emitting plate member with an LED as the light source, and it displays guidance to prompt operation of the transmitter 24 by flashing the light-emitting plate member.

[0112] Furthermore, a speaker unit 45 is provided on the lower side of the electrical door 20. The speaker unit 45 outputs a predetermined voice message prompting the road user to operate the transmitter 24 if they open the fire hydrant door 15 or fire extinguisher door 18 without operating the transmitter 24.

[0113] A handle touch switch 42 is provided on the door handle 1810 of the fire extinguisher door 18. The handle touch switch 42 detects human contact with the door handle 1810. Its configuration, function, and type are arbitrary, but for example, a pressure-sensitive switch that turns on when it detects the pressure applied to the handle when a person operates it, or a capacitive switch that turns on when it detects the change in capacitance when a person touches the handle, can be used.

[0114] The fire extinguisher door 18 is equipped with a fire extinguisher door open detection switch 40, which 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. Its structure and type are arbitrary, but for example, a limit switch equipped with a switch knob or switch lever that extends and retracts with the opening and closing of the door can be used. As an example, the fire extinguisher door open detection switch 40 is off when the fire extinguisher door 18 is closed and on when the fire extinguisher door 18 is open.

[0115] (d2. Functional configuration of the control unit) The control unit provided in the fire extinguisher box 100 will be described in more detail. As shown in Figure 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 Figure 4, excluding the fire hydrant input unit 70.

[0116] The functional configuration of the control unit 480 will now be explained in more detail. As shown in Figure 9, the control unit 480 consists 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 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. The control unit 480 is provided with a guidance display unit 44, a speaker unit 45, and a fire alarm signal transmission unit 46 as output targets. The configuration and functions of the control unit 480 and its input and output targets are the same as in Figure 4, so the same reference numerals are used and their descriptions are omitted.

[0118] (d3. Control operation of the operating instructions in the fire extinguisher box) The control operation of the control unit 480 in Figure 9, which provides guidance on operating the fire extinguisher box, will be explained in more detail. As shown in Figure 10, the control unit 480 monitors the detection of the fire extinguisher door 18 being opened by the fire extinguisher door open detection switch 40 (step S11). If a vehicle fire occurs in the tunnel due to an accident or the like, and a road user attempts to open the fire extinguisher door 18, 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 has been opened (Yes in step S11).

[0119] At this time, if the road user is not operating the transmitter 24, the current detection unit 35 does not output a transmitter operation detection signal E1, which indicates that the transmitter 24 is off (Yes in step S12). The control unit 48 then drives the guidance display unit 44, which is provided in conjunction with the transmitter 24, to blink and outputs an audio message from the speaker unit 45 prompting the user to operate the transmitter 24, thereby providing guidance display and audio guidance for transmitter operation (step S13).

[0120] Here, when a road user operates the transmitter 24 after receiving the transmitter operation guidance display and voice guidance, the current detection unit 35 outputs a transmitter operation detection signal E1, which allows the control unit 48 to determine that the transmitter 24 is ON (No. in step S12), and the system returns to its initial state, stopping the transmitter operation guidance display and voice guidance.

[0121] In contrast, if a road user takes out 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). The system determines that a fire has occurred and closes the relay contact x1 by activating the relay X of the fire alarm signal transmission unit 46, thereby sending a fire alarm signal to the disaster prevention receiving panel 12 (step S15) and outputting a fire alarm.

[0122] [e. Variations of the present invention] Modifications of the fire hydrant system and fire extinguisher box according to the present invention will be described in more detail. In addition to the embodiments described above, the fire hydrant system and fire extinguisher box of the present invention include the following modifications.

[0123] (Transmission circuits for electrical equipment) In the above embodiment, the electrical equipment installed on the electrical door was an example of a P-type (Proprietary-type) transmission circuit that sends and receives signals on a signal line basis drawn from the disaster prevention monitoring panel. However, it may also be an R-type (Record-type) transmission circuit in which a unique address is set for each electrical door (emergency notification device), and an uplink signal indicating equipment control with the specified address is sent from the transmission unit installed on the electrical door to the transmission unit of the disaster prevention receiving panel, and a downlink signal containing the address and detection information is sent from the transmission unit of the disaster prevention receiving panel to the transmission unit of the electrical door.

[0124] (Instructions and notifications for operating the transmitter) In the above embodiment, a guidance display unit 44 and a speaker unit 45 for outputting voice messages are provided to provide guidance and notification to prompt operation of the transmitter, but a configuration in which only one of them is provided is also possible.

[0125] (Unauthorized opening of fire hydrant doors or fire extinguisher doors) In the above embodiment, when both the open detection switch and the handle touch switch outputs are obtained for the fire hydrant door or fire extinguisher door, the system detects the opening operation and provides operation guidance to prompt the user to operate the transmitter. However, if only the open detection switch outputs for the fire hydrant door or fire extinguisher door, it indicates an accidental opening of the fire hydrant door or fire extinguisher door due to vibration or the like. In this case, the system may be configured to transmit a predetermined warning signal from the control unit to the disaster prevention receiving panel to output a warning alarm.

[0126] (Inspection work) Furthermore, while fire hydrant systems and fire extinguisher boxes undergo periodic inspections, during these inspections, it can be confirmed that the operation guidance prompting the operator to operate the transmitter is properly transmitted when the inspector opens the fire hydrant door or fire extinguisher door without operating the transmitter.
