Description

Technical Field

[0001] The present invention relates to a disaster prevention system that connects terminal equipment including a fire hydrant device to a disaster prevention receiver and monitors for abnormalities, and to the fire hydrant device thereof.

Background Art

[0002] Conventionally, in tunnels such as highways and motorways that are areas to be extinguished, fire hydrant devices are installed as emergency facilities in the tunnel to construct a disaster prevention system. As fire hydrant equipment, the fire hydrant device includes, for example, a fire hose with a nozzle attached to its tip in a fire hydrant storage section inside a housing equipped with a fire hydrant door, valves including a fire hydrant valve, and a fire hydrant valve opening / closing lever as a fire hydrant valve opening / closing operation section, etc., which are stored and installed, and two fire extinguishers are stored in a fire extinguisher storage section inside a housing equipped with a fire extinguisher door. In addition, the fire hydrant device is generally installed by cutting out the tunnel wall surface at intervals of, for example, 50 meters in the longitudinal direction of the tunnel and embedding it.

[0003] In addition, in the tunnel, fire detectors for detecting fires are installed at intervals of, for example, 25 meters or 50 meters in the longitudinal direction of the tunnel to monitor for fires as an abnormality. The fire detectors are connected to signal lines and transmission lines drawn from a disaster prevention receiver installed in an electrical room or the like of the tunnel equipment. In addition, the fire detectors have detection areas in both directions in the longitudinal direction of the tunnel, and detect fires by receiving infrared energy in the wavelength band unique to flames radiated from the source of the fire that has occurred.

[0004] In general, since road users are not used to operating fire hydrant devices, when the fire hydrant door is opened, the fire hydrant device is designed to show an operation method nameplate that clearly shows the operation method in order by graphics or the like. However, it is difficult to correctly use the fire hydrant device by looking at the operation method nameplate under urgent situations such as a fire, and there is a risk that the operation of the fire hydrant device will take time and the fire extinguishing activity cannot be carried out appropriately and quickly.

[0005] Therefore, in order to solve this problem, fire hydrant systems are known that provide instructions on how to operate the fire hydrant system by displaying and / or by voice, in order to assist road users who are unfamiliar with operating fire hydrant systems (Patent Documents 1 and 2).

[0006] Conventional fire hydrant operation guides include systems that optically activate a display unit to indicate the location of the fire hydrant door handle when the push button on the fire hydrant system's transmitter is pressed, systems that optically activate a display unit to indicate the location of the fire hose nozzle when it is detected that the fire hydrant door has been opened, and systems that optically activate a display unit to indicate the location of the fire hydrant valve opening / closing lever when it is detected that the nozzle has been removed. These systems enable road users unfamiliar with fire hydrant operation to understand which part of the fire hydrant system to operate in the event of a fire or other emergency, and to operate the fire hydrant system correctly. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2003-310785 [Patent Document 2] Japanese Patent Publication No. 2002-102380 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, in urgent situations such as a fire, there is no guarantee that road users will perform the correct operations according to the operating instructions. Even if operating instructions are provided, as with conventional fire hydrant systems, users may perform actions that should be done later, and conventional fire hydrant systems were insufficient to suppress and prevent user errors and to ensure that road users operate them in the correct procedure.

[0009] For example, even though the fire hydrant system guides users to remove the nozzle, road users may mistakenly operate the fire hydrant valve opening / closing lever first. Conventional fire hydrant systems do not have a mechanism to handle such errors and will continue to guide users to remove the nozzle. In this case, road users must realize their mistake and return the fire hydrant opening / closing lever to its original position. If the lever is not returned to its original position, firefighting water will be discharged from the nozzle held in the nozzle holder, causing the discharged water to scatter inside and around the casing, potentially leading to unexpected flooding damage. Furthermore, the difficulty in removing the nozzle that has started discharging water could seriously hinder firefighting efforts.

[0010] The present invention aims to provide a disaster prevention system and a fire hydrant system that monitor the operation of fire hydrant equipment in a fire hydrant system, provide guidance to ensure correct operation procedures are followed, and also provide appropriate guidance to alert users to errors in operation. [Means for solving the problem]

If it receives operation event information other than the operation event information indicating the opening of the fire hydrant door, it outputs an operation guidance indicating that it is an incorrect operation and prompting the opening of the fire hydrant door. Upon receiving operation event information indicating the operation of the transmitter and the opening of the fire hydrant door, and then receiving operation event information indicating the nozzle removal operation transmitted from the event detection unit based on the nozzle removal, the system will output an operation guidance message to open the fire hydrant valve opening / closing control unit. If operation event information other than that indicating the nozzle removal operation is received, the system will output an operation guidance message indicating that it is an incorrect operation and prompting the user to remove the nozzle. After receiving operation event information indicating the operation of the transmitter, the opening of the fire hydrant door, and the removal of the nozzle, if the system receives operation event information indicating the opening of the fire hydrant valve lever transmitted from the event detection unit based on the opening of the fire hydrant valve lever, it outputs an operation guide instructing the user to pull out the fire hose and discharge water from the nozzle. If the system receives operation event information other than the opening of the fire hydrant valve lever, it outputs an operation guide indicating that it is an incorrect operation and prompting the user to open the fire hydrant valve lever.

[0013] (Operational guidance control when a fire detector transmits a fire signal) A fire detector is connected to the disaster prevention receiver panel as a terminal device. When the disaster prevention receiving board receives a fire signal transmitted by a fire detector detecting a fire, the operation monitoring unit outputs an operation guide instructing to confirm the fire in the fire hydrant device corresponding to the detection area of the fire detector that transmitted the fire signal and to prompt a fire report by operating the transmitter.

[0014] (Operation guide control when the fire hydrant door is opened without a fire report) When the operation monitoring unit receives operation event information indicating the opening of the fire hydrant door without receiving operation event information indicating the operation of the transmitter, it outputs an operation guide instructing to confirm the fire and to prompt a fire report by operating the transmitter.

[0015] (Operation guide by display and voice) The fire hydrant device is provided with an operation guide display unit that displays an instruction to prompt an operation at a position corresponding to each of the transmitter, the fire hydrant door, the nozzle, and the fire hydrant valve opening / closing operation unit, and is provided with a voice output unit that outputs an operation guide by voice. When the operation monitoring unit outputs an operation guide instructing to prompt an operation, it activates the corresponding operation guide display unit and outputs a voice message of the corresponding operation guide from the voice output unit.

[0016] (Installation locations of the event detection unit and the operation monitoring unit) The event detection unit is provided in the fire hydrant device, and the operation monitoring unit is provided in the disaster prevention receiving board.

[0017] (Fire hydrant device) The present invention is a fire hydrant device installed connected to a disaster prevention receiving board, an event detection unit that detects an operation event of a predetermined fire hydrant device included in the fire hydrant device and transmits operation event information indicating the operation event, When the operation event information transmitted by the event detection unit is a correct operation event of the fire hydrant equipment, an operation guidance for prompting an operation for the next operation event of the operation event is output based on a predetermined control. When the operation event information transmitted by the event detection unit is not a correct operation event of the fire hydrant equipment, an operation guidance unit that provides an operation guidance indicating that it is an incorrect operation and / or prompting an operation for the correct operation event based on a predetermined control, is characterized by including.

[0018] (Operation guidance of fire hydrant device) As fire hydrant equipment, a transmitter that sends a fire alarm by transmitting a fire alarm signal, a fire hydrant door that is opened when pulling out a fire hose housed inside the fire hydrant device, a nozzle attached to the fire hose and detachably held by a nozzle holding part, a fire hydrant valve opening / closing operation part that opens and closes a fire hydrant valve provided in a pipe that supplies fire extinguishing water to the fire hose, including, The operation guidance unit, after transmitting operation event information indicating an operation of the transmitter based on a fire alarm signal transmitted by the event detection unit from the transmitter, and transmitting an operation event indicating an opening operation of the fire hydrant door based on the opening of the fire hydrant door, outputs an operation guidance for prompting the removal of the nozzle based on a predetermined control. When transmitting operation event information other than the operation event information indicating the opening operation of the fire hydrant door, outputs an operation guidance indicating that it is an incorrect operation and prompting an opening operation of the fire hydrant door based on a predetermined control. after the event detection unit transmits operation event information indicating an operation of the transmitter and an opening operation of the fire hydrant door, and transmits operation event information indicating a removal operation of the nozzle transmitted from the event detection unit based on the removal of the nozzle, outputs an operation guidance for prompting an opening operation of the fire hydrant valve opening / closing operation part based on a predetermined control. When transmitting operation event information other than the operation event information indicating the removal operation of the nozzle, outputs an operation guidance indicating that it is an incorrect operation and prompting a removal operation of the nozzle based on a predetermined control. If the event detection unit transmits operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, and the operation of removing the nozzle, and then transmits operation event information indicating the opening of the fire hydrant valve control unit based on the opening operation of the fire hydrant valve control unit transmitted from the event detection unit, the unit outputs operation guidance to pull out the fire hose and discharge water from the nozzle based on predetermined control. If it transmits operation event information other than the operation of opening the fire hydrant valve control unit, the unit outputs operation guidance indicating that it is an error operation and prompting the user to open the fire hydrant valve control unit based on predetermined control.

[0019] (Instructions for when the fire detector transmits a fire signal) The fire hydrant system is installed in a location corresponding to the detection area of ​​a predetermined fire detector connected to the fire prevention receiving panel. When the corresponding fire detector transmits a fire signal, the operation guidance unit outputs operation guidance indicating that the fire has been confirmed and prompting the user to report the fire by operating the transmitter, based on predetermined control.

[0020] (Instructions for when a fire hydrant door is opened without a fire alarm) If the event detection unit transmits operation event information indicating the opening of a fire hydrant door without transmitting operation event information indicating the operation of a transmitter, the operation guidance unit will output operation guidance based on predetermined control, stating that a fire has been confirmed and prompting the user to report the fire by operating the transmitter.

[0021] (Operation guidance via display and voice) The operation guide section is, An operation guidance display unit is provided at a position corresponding to the transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing operation unit, and displays instructions to prompt operation. An audio output unit that outputs operating instructions by voice, Equipped with, When outputting operation guidance prompting an action based on predetermined control, the corresponding operation guidance display unit is activated and the corresponding operation guidance voice message is output from the voice output unit. [Effects of the Invention]

[0022] (Effectiveness of disaster prevention systems) The present invention relates to a disaster prevention system that monitors abnormalities by connecting terminal equipment including a fire hydrant device to a disaster prevention receiving panel, and comprises: an event detection unit that detects a predetermined operation event of a fire hydrant device provided on the fire hydrant device and transmits operation event information indicating the operation event; and an operation monitoring unit that, when it receives operation event information indicating a correct operation event of the fire hydrant device from the event detection unit, causes the fire hydrant device to output operation guidance prompting the user to perform the next operation event, and when it receives operation event information indicating an incorrect operation of the fire hydrant device from the event detection unit, causes the fire hydrant device to output operation guidance indicating that it is an incorrect operation and prompting the user to perform the correct operation event. As a result, when the fire hydrant device is operated in the correct procedure, operation guidance prompting the user to perform the next operation enables even road users unfamiliar with handling fire hydrant devices to quickly perform the correct operations in the predetermined order.

[0023] Furthermore, if a fire hydrant system is not operated according to the correct procedure, the system will display instructions indicating that it is an error and prompting users to perform the correct operation. This will allow road users to realize they have made an error and learn the correct procedure they should have followed, enabling them to appropriately recover from the error and prevent unforeseen incidents.

[0024] (Effects of operation guidance control) Furthermore, the fire hydrant equipment includes a transmitter that issues a fire alarm by transmitting a fire alarm signal, a fire hydrant door that opens when the fire hose stored inside the fire hydrant device is pulled out, a nozzle attached to the fire hose and detachably held in the nozzle holder, and a fire hydrant valve opening / closing operation unit that opens and closes the fire hydrant valve provided in the piping that supplies fire extinguishing water to the fire hose. The operation monitoring unit receives operation event information indicating the operation of the transmitter transmitted from the event detection unit based on the fire alarm signal transmitted from the transmitter, and if it receives operation event information indicating the operation of opening the fire hydrant door transmitted from the event detection unit based on the opening of the fire hydrant door, it outputs an operation guidance prompting the removal of the nozzle. If it receives operation event information other than the operation of opening the fire hydrant door, it outputs an operation guidance indicating that it is an incorrect operation and prompting the opening of the fire hydrant door. After receiving operation event information indicating the operation of the transmitter and the operation of opening the fire hydrant door, it outputs an operation guidance indicating the operation of removing the nozzle transmitted from the event detection unit based on the removal of the nozzle. When operation event information is received, the system outputs instructions to open the fire hydrant valve control unit. When operation event information other than that indicating the nozzle removal operation is received, the system outputs instructions indicating that it is an incorrect operation and prompts the user to remove the nozzle. After receiving operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, and the operation of removing the nozzle, the system receives operation event information indicating the opening of the fire hydrant valve control unit transmitted from the event detection unit based on the opening operation of the fire hydrant valve control unit, and outputs instructions to pull out the fire hose and discharge water from the nozzle. When operation event information other than that indicating the opening of the fire hydrant valve control unit is received, the system outputs instructions indicating that it is an incorrect operation and prompts the user to open the fire hydrant valve control unit. As a result, road users can quickly operate the fire hydrant system in the correct procedure by following the instructions, including reporting a fire with the transmitter, opening the fire hydrant door, removing the nozzle, opening the fire hydrant valve control unit, and pulling out the hose.

[0025] Furthermore, if a fire hydrant system is not operated according to the correct procedure, instructions indicating that it is an error and prompting the user to perform the correct operation will allow road users to realize that they have made an error and learn the correct procedure they should have followed. This will enable them to appropriately recover from the error and prevent unforeseen incidents.

[0026] (Effects of operation guidance control when a fire detector transmits a fire signal) Furthermore, a fire detector is connected to the disaster prevention receiving panel as a terminal device, and when the disaster prevention receiving panel receives a fire signal transmitted by the fire detector after detecting a fire, the operation monitoring unit is configured to output operational guidance to the fire hydrant device corresponding to the detection area of ​​the fire detector that transmitted the fire signal, instructing it to confirm the fire and to prompt fire reporting by operating the transmitter. As a result, guidance on fire confirmation and transmitter operation, which should be performed first at the fire hydrant device located near the fire site, corresponding to the detection area of ​​the fire detector that detected the fire, is output, enabling road users to know which fire hydrant device to use and to operate it quickly using the correct procedure.

[0027] (Effects of operation guidance control when a fire hydrant door is opened without a fire alarm) Furthermore, the operation monitoring unit is configured to output an operation guidance message stating that a fire has been confirmed and urging users to report the fire by operating the transmitter, in the event of an emergency and chaotic situation such as a fire. In such cases, road users may attempt to pull out a fire hose and open the fire hydrant door first without reporting the fire by operating the transmitter. However, by providing an operation guidance message stating that a fire has been confirmed and urging them to report the fire by operating the transmitter, it is possible to prevent situations where a fire report is not made.

[0028] (Effectiveness of on-screen and voice guidance) Furthermore, the fire hydrant system is equipped with operation guidance display units that indicate prompts for operation at the locations corresponding to the transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing control unit, as well as an audio output unit that outputs operation guidance audibly. The operation monitoring unit activates the corresponding operation guidance display unit and outputs the corresponding voice message from the audio output unit when it is necessary to output operation guidance prompts for operation. As a result, through display and audio operation guidance, even road users unfamiliar with the operation of fire hydrant systems can be sure to know where the transmitter, fire hydrant door, nozzle, or fire hydrant valve opening / closing control unit is located on the fire hydrant system and what operating procedure to follow, enabling them to operate the fire hydrant system correctly and quickly.

[0029] (Effectiveness of fire hydrant systems) The present invention provides a fire hydrant system installed connected to a disaster prevention receiving panel, comprising: an event detection unit that detects operation events of predetermined fire hydrant equipment and transmits operation event information indicating said operation events; and an operation guidance unit that, if the operation event information transmitted by the event detection unit is a correct operation event of the fire hydrant equipment, outputs operation guidance prompting the user to perform an operation for the next operation event based on predetermined control; and if the operation event information transmitted by the event detection unit is not a correct operation event of the fire hydrant equipment, provides operation guidance based on predetermined control indicating that it is an incorrect operation and / or prompting the user to perform an operation for the correct operation event. As such, the same effects as a disaster prevention system can be obtained with other configurations of the fire hydrant system. [Brief explanation of the drawing]

[0031] The following describes in detail embodiments of the disaster prevention system and its fire hydrant device according to the present invention, based on the drawings. However, the present invention is not limited to the following embodiments.

[0032] [Basic Concepts of the Embodiment] First, the basic concept of the embodiment will be explained. The embodiment generally relates to a disaster prevention system that monitors abnormalities by connecting terminal equipment, including a fire hydrant device, to a disaster prevention receiving panel.

[0033] Here, "fire hydrant system" refers to a type of emergency equipment used to construct a fire prevention system installed in areas that are subject to fire suppression, such as tunnels on expressways and motorways. This includes systems that house fire hoses and fire extinguishers, as well as those equipped with emergency notification devices such as red indicator lights and transmitters.

[0034] Furthermore, a "disaster prevention receiving panel" is installed in the electrical room of a facility or equipment that constructs a disaster prevention system. It monitors abnormalities in the area to be extinguished by connecting terminal equipment of emergency equipment such as fire hydrants and fire detectors installed in the area to be extinguished. For abnormality monitoring, for example, terminal equipment is connected via signal lines or transmission lines, and downstream signals containing control information are sent to the terminal equipment to cause each terminal equipment to perform a predetermined operation. At the same time, upstream signals containing detection information regarding abnormalities from the terminal equipment and information regarding the status of each terminal equipment are received to perform receiving processing such as alarm processing and monitoring the status of the terminal equipment. In addition, there are two types of transmission between the disaster prevention receiving panel and terminal equipment: "R-type (Recorded type) transmission," which sets a unique address for each terminal equipment, including fire hydrants and fire detectors, and transmits and receives signals; and "P-type (Proprietary-type) transmission," which connects terminal equipment on a line-by-line basis and transmits and receives signals.

[0035] Furthermore, the "fire detector" included in the terminal equipment is installed in the area to be extinguished and detects fires occurring in that area. For example, if the area to be extinguished is inside a tunnel, it may be installed at intervals of 25 meters or 50 meters along the length of the tunnel, with detection areas in both directions along the length of the tunnel, and it may detect a fire by receiving infrared energy in the wavelength band specific to the flame emitted from the fire source and transmit a fire signal.

[0036] Furthermore, the "disaster prevention system" of the embodiment is characterized by comprising an event detection unit and an operation monitoring unit. In addition, the location of the event detection unit and the operation monitoring unit in the disaster prevention system is arbitrary, but this includes, for example, a system in which the event detection unit is installed in the fire hydrant device and the operation monitoring unit is installed in the disaster prevention receiving panel.

[0037] Here, the "event detection unit" detects operation events of predetermined fire hydrant equipment installed in the fire hydrant system and transmits operation event information indicating said operation events, and the "operation monitoring unit" receives operation event information from the event detection unit that has been set as a correct operation event for the fire hydrant equipment and causes the fire hydrant system to output operation guidance prompting the user to perform the next operation event after the said operation event, and if the event detection unit receives operation event information that has not been set as a correct operation event for the fire hydrant equipment and causes the fire hydrant system to output operation guidance indicating that it is an incorrect operation and prompting the user to perform the correct operation event.

[0038] Furthermore, "specified fire hydrant equipment installed in a fire hydrant system" refers to any fire hydrant equipment that detects operation, and includes, for example, a transmitter, a fire hydrant door, a nozzle attached to a fire hose, and a fire hydrant valve opening / closing control unit.

[0039] Here, "transmitter" refers to a device that transmits a fire alarm signal by operating a push button or the like to make a fire alarm. "Fire hydrant door" refers to a door that is opened when the fire hose stored inside the fire hydrant system is pulled out, and includes, for example, a door that is unlocked and opened by operating a door handle provided on the fire hydrant door. "Nozzle" refers to a nozzle that is attached to the fire hose and is detachably held in the nozzle holder, and is the nozzle end from which fire extinguishing water is discharged. "Fire hydrant valve opening / closing operation unit" refers to a unit that opens and closes the fire hydrant valve provided in the piping that supplies fire extinguishing water to the fire hose, and can be any structure as long as it can open and close the fire hydrant valve to discharge water from the nozzle of the fire hose and stop the discharge, and includes, for example, a fire hydrant valve opening / closing lever that can open and close the fire hydrant valve by operating a lever.

[0040] Furthermore, the "detection of fire hydrant equipment operation events" by the event detection unit includes not only the detection of fire hydrant equipment operation, but also the detection of events resulting from the operation of fire hydrant equipment. For example, if the fire hydrant equipment is a transmitter, it does not simply detect that the transmitter was operated by a push button or the like as an operation event, but also includes detecting the "transmission of a fire alarm signal" as a result of the transmitter being operated as an operation event for the transmitter.

[0041] Furthermore, the "operation event information" transmitted from the event detection unit is arbitrary as long as it allows the operation monitoring unit, which is the recipient of the transmission, to determine, identify, and detect the operation event detected by the event detection unit based on the received operation event information. For example, this could be bit information in which each operation event is listed as 1 bit information, or more specifically, a bit information corresponding to an operation event is set to "0" when no operation event is detected, and to "1" when an operation event is detected. It should be noted that this does not prevent the inclusion of information about multiple operation events within a single operation event information, as in the specific example of bit information in which operation event information is listed.

[0042] Furthermore, "operation event information that represents a correct operation event of the fire hydrant equipment" refers to operation event information based on an operation event that occurs when the correct operation procedure for handling the fire hydrant system is performed. On the other hand, "operation event information that represents an incorrect operation event of the fire hydrant equipment" refers to operation event information based on an operation event that occurs when an incorrect operation procedure for handling the fire hydrant system is performed. Here, the operation monitoring unit has the discretion to determine what operation event information constitutes a correct operation event, and this is set considering the fire hydrant equipment installed in the fire hydrant system, the operation procedure for the fire hydrant system, the designer's design philosophy, etc.

[0043] To give a specific example, if a fire hydrant system includes a transmitter, a fire hydrant door, a nozzle, and a fire hydrant valve opening / closing control unit, and the correct operating procedure for the fire hydrant system is to perform the following actions in this order: operating the transmitter, opening the fire hydrant door, removing the nozzle, and opening the fire hydrant valve opening / closing control unit, then the following four actions would be considered "operation event information that represents the correct operation of the fire hydrant system": "operation event information indicating the operation of the transmitter," "operation event information indicating the operation of the fire hydrant door after receiving operation event information indicating the operation of the transmitter and the operation of the fire hydrant door," "operation event information indicating the operation of the nozzle after receiving operation event information indicating the operation of the transmitter, the operation of the fire hydrant door, and the operation of the nozzle," and "operation event information indicating the operation of the fire hydrant valve opening / closing control unit after receiving operation event information indicating the operation of the transmitter, the operation of the fire hydrant door, and the operation of the nozzle." Furthermore, other operational event information, such as "operational event information indicating the opening of a fire hydrant door without receiving operational event information indicating the operation of a transmitter," which occurs when a fire hydrant door is opened without a fire alarm being issued, falls under the category of "operational event information that is not a correct operational event of the fire hydrant equipment."

[0044] Furthermore, when the fire alarm receiving panel receives a fire signal transmitted by a fire detector, the operation monitoring unit controls the system to output an operation guide to the fire hydrant device corresponding to the detection area of ​​the fire detector that transmitted the fire signal, stating that a fire has been confirmed and prompting the user to report the fire by operating the transmitter. In addition, "fire hydrant device corresponding to the detection area of ​​the fire detector" includes, for example, fire hydrant devices installed within or near the detection area of ​​the fire detector, or in a location close to the location where the fire occurred.

[0045] Furthermore, if the operation monitoring unit receives operation event information indicating the opening of a fire hydrant door without receiving operation event information indicating the operation of a transmitter, it will perform control to output operation guidance indicating that a fire has been confirmed and prompting the user to report the fire by operating the transmitter.

[0046] Furthermore, the "fire hydrant device" of this embodiment is provided with an operation guidance display unit that displays instructions for operation at positions corresponding to the transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing operation unit, as an operation guidance unit for outputting operation guidance, and is also provided with an audio output unit that outputs operation guidance in voice.

[0047] Furthermore, the "locations corresponding to the transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing operation unit" where the operation guidance display unit is provided include, for example, the location of each of the transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing operation unit, or a location near each of them. In addition, the "voice output unit" is optional as long as it can convey operation guidance to road users by voice, and includes, for example, a speaker unit equipped with a speaker.

[0048] Furthermore, when the operation monitoring unit is instructed to output operation guidance to the operation guidance display unit and the voice output unit, it activates the corresponding operation guidance display unit and outputs the corresponding operation guidance voice message from the voice output unit.

[0049] The following describes a specific embodiment. In the specific embodiment shown below, the "disaster prevention system" is "a tunnel disaster prevention system constructed in a tunnel on an expressway, connecting a fire hydrant device and a fire detector to a disaster prevention receiving panel and transmitting and receiving signals by R-type transmission", the "fire hydrant equipment" is "including a transmitter, fire hydrant door, nozzle, and fire hydrant valve opening / closing lever", the "nozzle holding part" is "nozzle holder", the "correct operating procedure for the fire hydrant device" is "operation in the order of operating the transmitter, opening the fire hydrant door, removing the nozzle, and opening the fire hydrant valve opening / closing operation part", and "event The "operation detection unit" is described as "a terminal control device installed in a fire hydrant system that has the function of detecting operation events of fire hydrant equipment and transmitting operation event information indicating said operation event," the "operation monitoring unit" is described as "implemented in the control unit of the disaster prevention receiving panel," and the "operation guidance unit" is described as "a unit provided as an operation guidance display unit for a fire hydrant system, which includes a transmitter operation guidance display unit, a fire hydrant door opening operation guidance display unit, a nozzle removal operation guidance display unit, and a valve opening / closing lever operation guidance display unit, and a speaker unit provided as an audio output unit."

[0051] [a. Tunnel disaster prevention system] This section will explain the tunnel disaster prevention system. Refer to Figure 1, which illustrates the tunnel disaster prevention system, for further explanation.

[0052] As shown in Figure 1, two tunnels, an uphill tunnel 1 and a downhill tunnel 2, are constructed as an expressway tunnel, and the uphill tunnel 1 and the downhill tunnel 2 are connected by an evacuation tunnel 3. Inside the uphill tunnel 1 and the downhill tunnel 2, fire detectors 16 are installed along the longitudinal walls of the tunnels, for example, at intervals of 50 meters. The fire detectors 16 have a detection area set to 50 meters on both sides in the longitudinal direction of the tunnel, and detect fires by receiving infrared energy emitted from flames caused by fires, etc. In addition, each fire detector 16 is assigned a unique address corresponding to the R-type transmission system.

[0053] Furthermore, inside the inbound tunnel 1 and the outbound tunnel 2, fire hydrant devices 20 are embedded and installed along the walls of the monitoring staff passages that run along the longitudinal direction of the tunnels, for example, at intervals of 50 meters. Details of the fire hydrant devices 20 will be described separately later.

[0054] Furthermore, a disaster prevention receiving panel 10 is installed in the tunnel's electrical room or other location to monitor for abnormalities, including fires, within the tunnel by connecting terminal equipment such as fire detectors 16 and fire hydrant systems 20 installed inside the tunnel. Details of the disaster prevention receiving panel 10 will be described separately later.

[0055] Furthermore, in order to connect the disaster prevention receiving panel 10 with each terminal device, a transmission cable 12 including transmission lines 1210, 1220, 1230, and 1240 is drawn out from the disaster prevention receiving panel 10. Transmission lines 1210 and 1220 are drawn out into the uphill tunnel 1, and transmission lines 1230 and 1240 are drawn out into the downhill tunnel 2. Fire detectors 16 are connected to transmission lines 1210 and 1230, and fire hydrant devices 20 are connected to transmission lines 1220 and 1240.

[0056] Furthermore, transmission lines 1210 to 1240 are wired via a relay amplification panel 18 installed inside the tunnel, and the relay amplification panel 18 relays and amplifies the signals transmitted and received between the fire detector 16 and fire hydrant system 20, which are installed far from the disaster prevention receiving panel 10, and the disaster prevention receiving panel 10.

[0057] Furthermore, the configuration of transmission lines 1210 to 1240 is arbitrary, but for example, it shall consist of a power line, a common line, and a transmission line for transmitting downlink signals in voltage mode from the disaster prevention receiving panel 10 to terminal equipment and uplink signals in current mode from the terminal equipment to the disaster prevention receiving panel 10. When transmitting downlink signals in voltage mode, for example, the downlink signal shall be transmitted as a voltage pulse that changes the line voltage between 18 volts and 30 volts. When transmitting uplink signals in current mode, for example, the signal current shall flow at the timing of bit 1 of the transmission data, and the uplink signal shall be transmitted as a so-called current pulse train. In the case of transmission using two-wire transmission lines 1210 to 1240 consisting of a transmission line and a common line, half-duplex communication shall be performed by switching between transmitting downlink signals in voltage mode and uplink signals in current mode.

[0058] In addition, other emergency tunnel equipment is installed, including fire pump equipment 24, IG substation equipment (intelligent substation equipment) 26, ventilation equipment 28, alarm display board equipment 30, radio rebroadcasting equipment 32, television monitoring equipment 34, and lighting equipment 36. These pieces of equipment are individually connected to the disaster prevention receiving panel 10 via P-type signal lines 14, with the exception of the IG substation equipment 26, which is connected to the disaster prevention receiving panel 10 via a data transmission line. In some cases, the transmission between the fire pump equipment 24 and the disaster prevention receiving panel 10 is R-type transmission, and the fire pump equipment 24 and the disaster prevention receiving panel 10 are connected via R-type transmission lines.

[0059] Here, the IG substation equipment 26 is communication equipment that connects the equipment installed inside the tunnel, including the disaster prevention receiving panel 10, with remote management equipment installed far outside the tunnel. The ventilation equipment 28 is equipment that energizes the air inside the tunnel by operating jet fans installed on the ceiling side of the tunnel, creating a ventilation flow in the longitudinal direction of the tunnel. The alarm display board equipment 30 is equipment that notifies road users inside the tunnel of abnormalities inside the tunnel by displaying them on an electronic display board. The radio rebroadcasting equipment 32 is equipment that enables road users and others inside the tunnel to receive information from the road administrator. The television monitoring equipment 34 is equipment that allows for confirmation of the scale and location of fires, operation of water spray equipment, and understanding the situation inside the tunnel when guiding evacuations. The lighting equipment 36 is equipment that drives the lighting fixtures inside the tunnel.

[0060] [b. Fire hydrant system] Next, we will explain the fire hydrant system. In this explanation, please refer to Figure 2, which shows the fire hydrant system; Figure 3, which shows the internal structure of the fire hydrant system from the front with the fire hydrant door, maintenance door, and fire extinguisher door in the open position; and Figure 4, which shows the configuration of the terminal control device installed in the fire hydrant system.

[0061] In the explanation of Figures 2 and 3, the X, Y, and Z directions are mutually orthogonal. Specifically, when viewing the front of the fire hydrant device with various doors, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction. Furthermore, in the X direction, the +X side is the right side and the -X side is the left side; in the Y direction, the +Y side is the upper side and the -Y side is the lower side; and in the Z direction, the +Z side is the front side and the -Z side is the rear side. Note that the Z direction is not shown in Figures 2 and 3.

[0062] (b1. Structure of fire hydrant system) First, let's explain the structure of the fire hydrant system. As shown in Figure 2, the fire hydrant system 20 has a structure divided into a housing 60 which houses the fire hydrant and a housing 62 which houses the fire extinguisher, and decorative frames 64 and 66 are attached to the front of the housings 60 and 62.

[0063] Furthermore, the door opening of the decorative frame 64 of the housing 60 is divided into upper and lower sections. A forward-tilting fire hydrant door 70 that opens downward by hinge is provided on the lower side of the door opening, and a maintenance door 68 that opens upward by hinge is provided on the upper side of the door opening. Inside this maintenance door, a fire hydrant storage compartment houses fire hydrant equipment including a fire hose and valves including a fire hydrant valve. The fire hydrant door 70 is equipped with a door handle 72, and when a road user puts their hand into the door handle 72 and pulls it towards them, the lock is released and the fire hydrant door 70 can be opened. The fire hydrant door 70 is treated as part of the fire hydrant equipment.

[0064] Furthermore, a door detection switch 74 is provided, for example, on the left side of the door opening of the fire hydrant door 70. The door detection switch 74 is a switch that operates when a road user pulls the door handle 72 towards them to open the fire hydrant door 70. 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 opening and closing operation of the fire hydrant door 70 is used. In this embodiment, the door detection switch 74 is turned off when the fire hydrant door 70 is closed and turned on when the fire hydrant door 70 is open.

[0065] Furthermore, the door handle 72 is provided with a door opening operation guidance display unit 76. The structure and function of the door opening operation guidance display unit 76 are arbitrary, but for example, it is a light-emitting panel member with an LED as the light source, which is arranged around the door handle 72 and flashes based on instruction information included in the control command signal from the disaster prevention receiving panel 10 to provide guidance prompting the opening of the fire hydrant door 70.

[0066] Furthermore, a fire extinguisher door 78 is provided on the left side of the door opening of the decorative frame 11b of the housing 10b, which 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 78 is equipped with a door handle 80, and when a road user puts their hand into the door handle 80 and pulls it towards them, the lock is released and the fire extinguisher door 78 can be opened. In addition, a viewing window 82 is provided on the lower side of the fire extinguisher door 78, allowing the presence or absence of fire extinguishers to be checked from the outside.

[0067] Furthermore, an electrical door 84 that opens horizontally to the right by a hinge is provided on the right side of the door opening of the decorative frame 11b. The electrical door 84 is equipped with electrical equipment such as a red indicator light 86, a transmitter 88, and a response lamp 90, and a telephone jack is provided inside the housing 62 of the electrical door 84. In addition, the red indicator light 22, transmitter 24, response lamp 26, and telephone jack provided on the electrical door 20 constitute an emergency notification device, and the transmitter 88 is treated as part of the fire hydrant equipment.

[0068] The red indicator light 86 is always lit so that the location of the fire hydrant device 20 can be seen from a distance. In the event of a fire, when the transmitter 88 is pressed and its push button switch is turned on, a fire alarm signal is transmitted. Based on the fire alarm signal, the disaster prevention receiving panel 10 outputs a fire alarm, and in response, the disaster prevention receiving panel 10 transmits a response signal to the fire hydrant device 20 using R-type transmission control, causing the red indicator light 86 to flash and the response lamp 90 to light up.

[0069] Furthermore, the transmitter 88 is equipped with a transmitter operation guidance display unit 96. The structure and function of the transmitter operation guidance display unit 96 are arbitrary, but for example, similar to the door opening operation guidance display unit 76, it is a light-emitting panel member with an LED as the light source, arranged around the transmitter 88, and provides guidance by flashing the light-emitting panel member based on instruction information included in the control command signal from the disaster prevention receiving panel 10 to prompt the user to press the push button on the transmitter 88.

[0070] Furthermore, a speaker unit 98 is provided on the lower side of the electrical door 84. Based on instruction information included in the control command signal from the disaster prevention receiving panel 10, the speaker unit 98 outputs predetermined voice messages prompting the operation of fire hydrant equipment, including pressing the buttons on the transmitter 88, opening the fire hydrant door 70, removing the nozzle, and opening the fire hydrant valve opening / closing lever, as well as pointing out any incorrect operation of the fire hydrant equipment.

[0071] (b2. Internal structure of a fire hydrant system) Next, the internal structure of the fire hydrant device 20 shown in Figure 2 will be explained. As shown in Figure 3, the inside of the housing 60, which serves as the fire hydrant storage section 100, is divided into a valve storage section 102 and a hose storage section 104.

[0072] In the valve storage section 102, a water tap 108 is connected to a water supply pipe 106 that is drawn in from the outside, and the water supply pipe 106 is branched downward and connected to a fire hose 114 via a fire hydrant valve 110 and an automatic pressure regulating valve 112.

[0073] The hose storage section 104 is equipped with a hose storage frame 116, which stores the fire extinguishing hose 114 that is pulled in from below by winding it inward clockwise or counterclockwise. A nozzle 120 is attached to the end of the fire extinguishing hose 114 that is pulled out through a hose guide 118 installed on the back side of the fire hydrant door 70, and the nozzle 120 is detachably held in a nozzle holder 122.

[0074] The fire hydrant valve 110 is opened and closed by a fire hydrant valve opening / closing lever 124 provided in an operation box 125 installed on the back side of the fire hydrant door 70. The fire hydrant valve 110 is opened and closed in conjunction with the opening and closing operation of the fire hydrant valve opening / closing lever 124 by a known wire link mechanism provided between the operation box 125 and an interlocking box 126 provided on the fire hydrant valve 110 in correspondence with the operation box 125.

[0075] Furthermore, a pump start interlocking switch 130 is provided in the interlocking box 126 that turns on and off in response to the opening and closing of the fire hydrant valve 110, and transmits a pump start signal when turned on. A pump start switch 128 is also provided to the upper right of the water tap 108 for use by the fire brigade, and transmits a pump start signal when turned on.

[0076] Furthermore, the operation box 125 is equipped with a valve opening / closing lever detection switch 136. The valve opening / closing lever detection switch 136 is activated when a road user operates the fire hydrant valve opening / closing lever 124 from the closed position to the open position. Its structure and type are arbitrary, but for example, a limit switch is used, similar to the door detection switch 74. In this embodiment, the valve opening / closing lever detection switch 136 is turned off when the fire hydrant valve opening / closing lever 124 is in the closed position shown in the figure, and turned on when the fire hydrant valve opening / closing lever 124 leaves the closed position.

[0077] Furthermore, the operating handle of the fire hydrant valve opening / closing lever 124 is equipped with a valve opening / closing lever operation guidance display unit 138. The structure and function of the valve opening / closing lever operation guidance display unit 138 are arbitrary, but for example, a light-emitting cylinder member with an LED as the light source is provided at the right end of the operating handle, and based on instruction information included in the control command signal from the disaster prevention receiving panel 10, the light-emitting cylinder member flashes to provide guidance prompting the opening operation of the fire hydrant valve opening / closing lever 124.

[0078] Furthermore, the nozzle holder 122 is provided with a nozzle detection switch 132. The nozzle detection switch 132 is a switch that operates when a road user removes the nozzle 120 from the nozzle holder 122. Its structure and type are arbitrary, but for example, a limit switch is used, similar to the door detection switch 74. In this embodiment, the nozzle detection switch 132 is turned off when the nozzle 120 is held in the nozzle holder 122, and turned on when the nozzle 120 is removed from the nozzle holder 122.

[0079] Furthermore, the nozzle holder 122 is provided with a nozzle removal operation guidance display unit 134. The structure and function of the nozzle removal operation guidance display unit 134 are arbitrary, but for example, similar to the door opening operation guidance display unit 76, it is a light-emitting plate member with an LED as the light source, arranged around the nozzle holder 122, and flashes the light-emitting plate member to provide guidance prompting the removal of the nozzle 120 based on instruction information included in the control command signal from the disaster prevention receiving panel 10.

[0080] Furthermore, an operating instructions plate 144 is located behind the nozzle holder 122 (on the inside of the housing side). The operating instructions plate 144 is divided into three sections and uses diagrams to show the procedures for removing the nozzle, opening the fire hydrant valve lever, and discharging water from the fire hose nozzle.

[0081] Furthermore, the interior of the housing 62 (the side with the fire extinguisher door 78) is a fire extinguisher storage section 65, which houses two fire extinguishers 140. Terminal boxes 92 and 94 are installed on the rear of the fire extinguisher storage section 65. A red indicator light 86 provided on the electrical door 84 is connected to terminal box 92 via a wiring cable, and a transmitter 88, response lamp 90, telephone jack and speaker section 98 provided on the electrical door 84, and a pump start switch 128 and pump start interlocking switch 130 provided in the valve storage section 102 are connected to terminal box 94 via wiring cables.

[0082] Furthermore, a cable rack 142 is installed above the valve storage section 102 within the housing 60, extending from near the center to the hose storage section 104. The cable rack 142 is used to pass high-voltage cables through which high-voltage cables drawn into the valve storage section 102 from the outside are connected to the terminal box 92, low-voltage cables through which low-voltage cables drawn into the valve storage section 102 from the outside are connected to the terminal box 94, and wiring cables from the pump start switch 128 and the pump start interlocking switch 130 are also passed through the terminal box 94.

[0083] Furthermore, a terminal control device 58 is installed below the terminal boxes 92 and 94 on the rear of the fire extinguisher storage section 65. The terminal control device 58 is where the transmission lines 1220 and 1240 drawn from the disaster prevention receiving panel 10 are connected, and it transmits and receives signals using R-type transmission control between it and the disaster prevention receiving panel 10. Details of the terminal control device 58 will be described separately. In addition, the wiring necessary for control by the terminal control device 58 may be routed through the cable rack 142.

[0084] (b3. Terminal control device) Next, we will describe the terminal control device installed in the fire hydrant system. As shown in Figure 4, the terminal control device 58 is equipped with a transmission unit 148 and a control unit 150.

[0085] The transmission unit 148 transmits and receives signals with the disaster prevention receiving panel 10 using R-type transmission control. The control unit 150 is a computer circuit equipped with a CPU, memory, and various input / output ports. The CPU executes a program to realize functions such as transmission control of operation event information, operation control of electrical equipment based on instruction information from the disaster prevention receiving panel 10, and output control of operation guidance. In addition, the transmission unit 148 has a unique address pre-set for transmitting and receiving signals with the disaster prevention receiving panel 10 using R-type transmission control.

[0086] Furthermore, the control unit 150 is connected to an emergency notification unit 152, which is operated and activated when a notification is made, consisting of a transmitter 88 and a response lamp 90. The pump start switch 128 and the pump start interlock switch 130 are connected to a pump equipment start unit 153, which is operated when starting the pump equipment. Alternatively, the pump start switch 128 and the pump start interlock switch 130 may be connected in parallel, resulting in a single input system for the control unit 150.

[0087] In addition, the control unit 150 is connected to an operation event detection unit 154 that detects operation events of the fire hydrant equipment when the fire hydrant system is operated, and includes a door detection switch 74, a nozzle detection switch 132, and a valve opening / closing lever detection switch 136. Furthermore, the operation guidance unit 156 that outputs operation guidance for the fire hydrant equipment is connected to an operation guidance unit 156 that includes a door opening operation guidance display unit 76, a transmitter operation guidance display unit 96, a nozzle removal operation guidance display unit 134, a valve opening / closing lever operation guidance display unit 138, and a speaker unit 98.

[0088] The control unit 150 detects an operation event of the fire hydrant equipment based on a fire alarm signal from the transmitter 88, a pump start signal from the pump start switch 128 or the pump start interlock switch 130, or an ON signal based on the ON status of any of the switches: the door detection switch 74, the nozzle detection switch 132, or the valve opening / closing lever detection switch 136. The control unit 150 then causes the transmission unit 148 to transmit a response signal to the disaster prevention receiving panel 10 containing operation event information indicating the detected operation event via R-type transmission control.

[0089] Furthermore, when the control unit 150 receives a control command signal (downlink signal) containing predetermined instruction information from the disaster prevention receiving panel 10 via the transmission unit 148, it performs control to activate the response lamp 90, door opening operation guidance display unit 76, transmitter operation guidance display unit 96, nozzle removal operation guidance display unit 134, valve opening / closing lever operation guidance display unit 138, or speaker unit 98 based on the instruction information contained in the control command signal. Details of the R-type transmission control performed with the disaster prevention receiving panel 10 will be described separately.

[0090] [c. Disaster Prevention Receiving Panel] Next, we will explain the disaster prevention receiving panel. For this explanation, please refer to Figure 5, which shows the configuration of the disaster prevention receiving panel.

[0091] (c1. Configuration of the disaster prevention receiving panel) As shown in Figure 5, the disaster prevention receiving panel 10 is equipped with a control unit 40, and the control unit 40 is further provided with transmission units 4210-4240, an alarm unit 45, a display unit 46, an operation unit 48, a modem 50, and a P-type transmission unit 52. The operation monitoring function is realized by the control unit 40.

[0092] The control unit 40 is a computer circuit equipped with a CPU, memory, various input / output ports, etc., and functions such as abnormality monitoring and control, alarm control, operation monitoring and control, and instruction information transmission control are realized by the execution of a program by the CPU.

[0093] Furthermore, transmission lines 1210 to 1240 are drawn from transmission units 4210 to 4240 to correspond to fire detectors 16 or fire hydrant devices 20 installed in the uphill tunnel 1 and downhill tunnel 2, respectively. The alarm unit 45 is equipped with a speaker and an alarm indicator light, the display unit 46 is equipped with a liquid crystal display, the operation unit 48 is equipped with various switches, a data transmission line for connecting the IG slave station equipment 26 is drawn from the modem 50, and individual P-type signal lines 14 are drawn from the P-type transmission unit 52 to connect the ventilation equipment 28, alarm display board equipment 30, radio rebroadcasting equipment 32, television monitoring equipment 34, lighting equipment 36, and fire pump equipment 24.

[0094] (c2. R-type transmission control performed with the fire detector) Next, we will explain the R-type transmission control performed with the fire detectors. The transmission units 4210 and 4230 of the disaster prevention receiving panel 10 connected to the fire detectors 16 perform R-type transmission control, sending and receiving signals according to a predetermined communication protocol. As a result, the disaster prevention receiving panel 10 individually detects the status of the fire detectors 16 and centrally monitors the fire detectors 16 that have detected a fire.

[0095] As an R-type transmission control performed with the fire detector 16, in the normal monitoring state, the transmission unit 4210 of the disaster prevention receiving panel 10 transmits polling command signals (downlink signals) in voltage mode, sequentially specifying the addresses of the fire detectors 16 connected to the transmission line 1210 at predetermined timings, for example, every minute, and receives response signals (uplink signals) transmitted in current mode from the fire detectors 16, thereby detecting the status of the fire detectors 16.

[0096] Then, when the fire detector 16 detects a fire by receiving infrared energy emitted from flames such as a fire, the fire detector 16 that has detected the fire sends an interrupt signal as a fire signal to the connected transmission line 1210. When the transmission unit 4210 of the disaster prevention receiving panel 10 receives the interrupt signal from the fire detector 16 that has detected the fire, it sends a group search command signal to the fire detector 16 to identify the group that has detected the fire, and then sends an in-group search command signal to the fire detector 16 of the identified group to search for the address of the fire detector 16 that has detected the fire, thereby identifying the fire detector 16 that has detected the fire. By specifying the address of the identified fire detector 16, the system sends a polling command signal at a shorter period than the period during normal monitoring and receives a response signal from the fire detector 16 that has detected the fire, thereby centrally monitoring the fire detector 16 that has detected the fire.

[0097] Here, an interrupt signal is a signal that is preferentially transmitted from the fire detector 16 that has detected a fire to the disaster prevention receiving panel 10, regardless of the transmission status of the downlink or uplink signal. The format of the interrupt signal is arbitrary, but for example, a signal that sets all the bit information of the uplink signal transmitted in current mode to 1 (a constant current signal) is used. Similarly, the transmission unit 4230 of the disaster prevention receiving panel 10 connected to the fire detector 16 in the downlink tunnel 2 also uses the same R-type transmission control.

[0098] (c3. R-type transmission control performed with fire hydrant systems) Next, we will explain the R-type transmission control performed with the fire hydrant system. The transmission units 4220 and 4240 of the disaster prevention receiving panel 10 connected to the fire hydrant system 20 perform R-type transmission control, sending and receiving signals according to a predetermined communication protocol. The disaster prevention receiving panel 10 individually detects and monitors the status of the fire hydrant system 20 and the operation events performed on the fire hydrant system 20, and also transmits instruction information to control the operation of the electrical equipment of the fire hydrant system 20 and the output of operation guidance.

[0099] As shown in Figure 3, the fire hydrant system 20 is equipped with a terminal control device 58 comprising a transmission unit 148 and a control unit 150. The transmission unit 148 of the terminal control device 58 receives polling command signals or control command signals, which are downlink signals, transmitted in voltage mode from the transmission units 4220 and 4240 of the disaster prevention receiving panel 10, and transmits response signals and interrupt signals, which are uplink signals, in current mode to the transmission units 4220 and 4230 of the disaster prevention receiving panel 10.

[0100] As an R-type transmission control performed with the fire hydrant system 20, in the normal monitoring state, the transmission unit 4220 of the disaster prevention receiver panel 10 transmits polling command signals (downlink signals) sequentially specifying the addresses of the fire hydrant systems 20 connected to the transmission line 1220 at predetermined timings, for example, every minute. When the transmission unit 148 of the terminal control device 58 provided on the fire hydrant system 20 receives a polling command signal specifying its own address, it outputs a signal to the control unit 150 indicating that it has received the polling command signal, and at the response timing following the reception of the polling command signal, it transmits a response signal (uplink signal) containing response information instructed by the control unit 150 to the disaster prevention receiver panel 10. The response information in the normal monitoring state is arbitrary, but for example, it may be status information indicating that the fire hydrant system 20 is in a normal state.

[0101] Furthermore, if the terminal control device 58 installed in the fire hydrant system 20 detects the input of a fire alarm signal, i.e., an ON signal from the push-button switch operated by the push-button operation of the transmitter 88, at the control unit 150, or detects the opening operation of the fire hydrant door 70, and has not yet sent an interrupt signal, the transmission unit 148 performs transmission control to send an interrupt signal to the disaster prevention receiving panel 10 at the instruction of the control unit 150.

[0102] In this case, the transmission control on the disaster prevention receiving panel 10 side is the same as when the fire detector 16 detects a fire and sends an interrupt signal as a fire signal to the disaster prevention receiving panel 10. When the transmission unit 4220 of the disaster prevention receiving panel 10 receives an interrupt signal from the fire hydrant device 20, it sends a group search command signal to the fire hydrant device 20 to identify the group of fire hydrant devices 20 that sent the interrupt signal, that is, the group of fire hydrant devices 20 that performed the fire alarm or the fire hydrant door 70 opening operation without a fire alarm. Subsequently, it sends an in-group search command signal to the fire hydrant devices 20 in the identified group to search for the address of the fire hydrant device 20 that sent the interrupt signal, thereby identifying the fire hydrant device 20 that sent the interrupt signal. By specifying the address of the identified fire hydrant device 20 and sending a polling command signal at a shorter period than the period in the normal monitoring state, it receives a response signal from the fire hydrant device 20 that sent the interrupt signal, thereby centrally monitoring the fire hydrant device 20 that sent the interrupt signal.

[0103] Furthermore, as transmission control after the disaster prevention receiving panel 10 has identified the fire hydrant device 20, the transmission unit 148 of the terminal control device 58 installed on the fire hydrant device 20 outputs a signal to the control unit 150 indicating that it has received a polling command signal when it receives a polling command signal specifying its own address. The control unit 150 then detects the on / off state (operation event) of the pump start switch 128, pump start interlock switch 130, door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136 at that time, and, in response timing following the receipt of the polling command signal, sends a response signal (up signal) to the disaster prevention receiving panel 10 that includes switch operation information indicating the operation of each switch as operation event information, in accordance with instructions from the control unit 150. Note that the switch operation information included in the response signal is one type of response information included in the response signal.

[0104] Here, "switch operation information" is arbitrary as long as the on / off state (operation event) of each switch can be detected on the disaster prevention receiver panel 10 side. For example, it corresponds to the six lines connected to the control unit 150 as input: transmitter 88, pump start switch 128, pump start interlock switch 130, door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136. It is 6-bit information, with bit 1 set when the switch is ON and bit 0 when the switch is OFF. In the following explanation, the first bit of the 6-bit information corresponds to transmitter 88, the second bit to pump start switch 128, the third bit to pump start interlock switch 130, the fourth bit to door detection switch 74, the fifth bit to nozzle detection switch 132, and the last bit to valve opening / closing lever detection switch 136.

[0105] The disaster prevention receiver panel 10 then detects the on / off state (operation event) of the transmitter 88 from the first bit of information in the switch operation information included in the response signal received by the transmission unit 4220 of the disaster prevention receiver panel 10. It also detects the on / off state (operation event) of the pump start switch 128 or the pump start interlock switch 130 from the second and third bits of information from the beginning of the switch operation information. If the bit information corresponding to either the pump start switch 128 or the pump start interlock switch 130 is bit 1, the control unit 40 of the disaster prevention receiver panel 10 controls the fire pump equipment 24 to start the pump.

[0106] Furthermore, the control unit 40 of the disaster prevention receiving panel 10 detects the on / off state (operation event) of the door detection switch 74, nozzle detection switch 132, and valve opening / closing lever detection switch 136 from the 4th to 6th bits of information from the beginning of the switch operation information. If the bit information corresponding to the door detection switch 74 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the opening operation of the fire hydrant door 70. If the bit information corresponding to the nozzle detection switch 132 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the removal operation of the nozzle 120. In addition, if the bit information corresponding to the valve opening / closing lever detection switch 136 is bit 1, the control unit 40 of the disaster prevention receiving panel 10 detects the opening operation of the fire hydrant valve opening / closing lever 124.

[0107] Furthermore, the disaster prevention receiving panel 10 controls the output of operation guidance from the fire hydrant device 20 in response to detected operation events, but the details of this will be described separately. Similarly, the transmission unit 4240 connected to the fire hydrant device 20 in the down-line tunnel 2 also uses the same R-type transmission control.

[0108] [d. Operation guidance and control of fire hydrant systems] Next, we will explain the operation guidance control of the fire hydrant system based on the coordination between the fire hydrant system and the disaster prevention receiving panel. In the following explanation, the operation guidance control will be divided into three parts: operation guidance control when the operation of the transmitter is first detected, operation guidance control when the fire detector first receives a fire signal, and operation guidance control when the opening operation of the fire hydrant door is first detected.

[0109] [e. Operational guidance and control based on the fire alarm signal from the transmitter] First, we will explain the operation guidance control when the disaster prevention receiver panel first detects operation of the transmitter.

[0110] (e1. Operation guidance control to prompt the opening of the fire hydrant door) The control unit 40 of the disaster prevention receiving panel 10 receives an interrupt signal from the terminal control device 58 of the fire hydrant device 20 when the transmission units 4220 and 4240 operate the push button on the transmitter 88 installed on the fire hydrant device 20, and identifies the address of the fire hydrant device 20 that sent the interrupt signal. Furthermore, it detects a fire alarm from the operation event information indicating the operation of the transmitter, which includes the response signal received from the identified fire hydrant device 20, and the already received interrupt signal. By combining this with the fire detection from the interrupt signal transmitted as a fire signal from the fire detector 16, it determines that there is a fire, and outputs a fire alarm from the alarm unit 45. It also controls the alarm display board equipment 30 to display, for example, a tunnel entry prohibited sign, and causes the transmission units 4220 and 4240 to send a control command signal to the identified fire hydrant device 20, which includes instruction information for opening the fire hydrant door 70.

[0111] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiver panel 10 that includes instruction information for door opening operation guidance with its own address specified, the control unit 150 prompts the fire hydrant door 70 to be opened. For example, it causes the door opening operation guidance display unit 76 to blink and outputs a predetermined voice message from the speaker unit 98: "Beep beep, pull the door handle to open the fire hydrant door." The voice data for the voice message output from the speaker unit 98 is either stored in the memory of the terminal control device 58 beforehand, or the voice data is transmitted from the disaster prevention receiver panel 10 to be output. The same applies to the output of other voice messages for operation guidance.

[0112] When a road user opens the fire hydrant door 70 based on these instructions, the door detection switch 74 turns ON, and the terminal control device 58, at the response timing following the receipt of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation of the transmitter and the opening of the fire hydrant door, i.e., switch operation information with the first and fourth bits set to bit 1.

[0113] Furthermore, the response lamp 90 installed on the fire hydrant device 20 lights up as an acknowledgment from the disaster prevention receiving panel 10 to a fire alarm from the transmitter 88. Therefore, the control command signal transmitted from the disaster prevention receiving panel 10 includes instruction information for lighting the response lamp 90. Upon receiving the control command signal containing the instruction information for the response lamp 90, the terminal control device 58 of the fire hydrant device 20 uses the control unit 150 to light up the response lamp 90. Note that the instruction information for lighting the response lamp 90 and the instruction information for door opening operation guidance may be included in the same control command signal, or they may be included in separate control command signals.

[0114] (e2. Operation guidance control to prompt the removal of the nozzle) Next, when the control unit 40 of the disaster prevention receiving panel 10 receives a response signal from the fire hydrant device 20 that includes operation event information indicating the operation of the transmitter and the opening of the fire hydrant door, it specifies the address of the identified fire hydrant device 20 and causes the transmission units 4220 and 4240 to transmit a control command signal that includes instruction information for nozzle removal operation guidance.

[0115] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiving panel 10 that includes instruction information for nozzle removal operation guidance to which its own address is specified, the control unit 150 prompts the removal of the nozzle 120 by flashing the nozzle removal operation guidance display unit 134 and outputting a predetermined voice message from the speaker unit 98: "Beep beep beep. Remove the nozzle from the nozzle holder and pull out the hose."

[0116] Based on these instructions, when a road user removes the nozzle 120 from the nozzle holder 122, the nozzle detection switch 132 turns ON, and the terminal control device 58, in response timing following the receipt of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, and the operation of removing the nozzle, i.e., switch operation information with the first bit and the fourth and fifth bits from the beginning set to bit 1.

[0117] (e3. Operation guidance control to prompt the opening of the fire hydrant valve lever) Next, when the control unit 40 of the disaster prevention receiving panel 10 receives a response signal from the fire hydrant device 20 that includes operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, and the operation of removing the nozzle, it specifies the address of the identified fire hydrant device 20 and causes the transmission units 4220 and 4240 to transmit a control command signal that includes instruction information for guiding the opening operation of the fire hydrant valve opening / closing lever.

[0118] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiver panel 10 that includes instruction information for opening the fire hydrant valve opening / closing lever to which its own address is specified, the control unit 150 prompts the fire hydrant valve opening / closing lever 124 to be opened by, for example, flashing the valve opening / closing lever operation guidance display unit 138 and outputting a predetermined voice message from the speaker unit 98: "Beep beep beep. Please open the fire hydrant valve opening / closing lever. Water discharge will begin. Please hold the nozzle firmly."

[0119] Based on these instructions, when a road user opens the fire hydrant valve opening / closing lever 124, the valve opening / closing lever detection switch 136 turns ON, and the terminal control device 58, in response timing following the receipt of a polling command signal specifying its own address, transmits a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, the operation of removing the nozzle, and the operation of opening the fire hydrant valve opening / closing lever, i.e., switch operation information with the first bit and the 4th to 6th bits from the beginning set to bit 1.

[0120] Then, the disaster prevention receiving panel 10, which has received a response signal containing operation event information indicating the opening of the fire hydrant door, the removal of the nozzle, and the opening of the fire hydrant valve opening / closing lever, specifies the address of the fire hydrant device 20 identified by the control unit 40 and causes the transmission units 4220 and 4240 to transmit a control command signal containing instruction information for water discharge operation guidance.

[0121] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiving panel 10 that includes instruction information for water discharge operation guidance to which its own address is specified, the control unit 150 causes the speaker unit 98 to output a predetermined voice message, for example, "Point the nozzle towards the fire and pull out the hose while discharging water. Discharge water from a position sufficiently far away from the fire."

[0122] (e4. Instructions for correcting user errors) Here, if, despite the fire hydrant device 20 outputting an operation guide prompting the user to remove the nozzle, the road user mistakenly opens the fire hydrant valve opening / closing lever 124 without removing the nozzle 120, the valve opening / closing lever detection switch 136 turns ON, and the terminal control device 58, in response timing following the reception of a polling command signal specifying its own address, sends a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation of the transmitter, the operation of opening the fire hydrant door, and the operation of opening the fire hydrant valve opening / closing lever, i.e., switch operation information with the first bit and the 4th and 6th bits from the beginning set to bit 1.

[0123] However, the operation to open the fire hydrant valve lever 124 performed by the road user following the opening of the fire hydrant door 70 is an incorrect operation that differs from the correct operating procedure for the fire hydrant system. The disaster prevention receiving panel 10 does not receive a response signal containing operation event information indicating a nozzle removal operation, i.e., a response signal containing switch operation information with the fifth bit from the beginning set to bit 1. Instead, it receives a response signal containing operation event information indicating the opening of the fire hydrant valve lever 124, i.e., a response signal containing switch operation information with the sixth bit from the beginning set to bit 1. Therefore, the control unit 40 of the disaster prevention receiving panel 10 can detect that the operation to open the fire hydrant valve lever 124 performed following the opening of the fire hydrant door 70 is an incorrect operation, and causes the transmission units 4220 and 4240 to send a control command signal containing instruction information indicating that it is an incorrect operation and prompting the user to remove the nozzle, specifying the address of the identified fire hydrant system.

[0124] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiver panel 10 that includes instruction information indicating that an error has occurred specifying its own address and prompting the user to remove the nozzle, the control unit 150 outputs, for example, a predetermined voice message from the speaker unit 98 indicating that an error has occurred, such as "Beep beep, beep, opening the fire hydrant valve lever is an error. Please return the lever to its original position." and, as an operation guidance prompting the user to remove the nozzle, which is the correct operation, the nozzle removal operation guidance display unit 134 flashes and the speaker unit 98 outputs a predetermined voice message, such as "Beep beep, beep, remove the nozzle from the nozzle holder and pull out the hose."

[0125] Therefore, road users can recover from the error by realizing that opening the fire hydrant valve lever 124 was an error, returning the fire hydrant valve lever 124 to its original closed position, and then taking out the nozzle 120 as the correct operation. Following this recovery operation, the nozzle detection switch 132 turns ON and the valve lever detection switch 136 turns OFF. Consequently, the terminal control device 58, in response to the polling command signal specifying its own address, sends a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the operation of the transmitter, the opening of the fire hydrant door, and the taking out of the nozzle, but does not include operation event information indicating the opening of the fire hydrant valve lever 124. In other words, the first and fourth and fifth bits from the beginning are set to bit 1, and the sixth bit from the beginning is set to bit 0. The subsequent operation guidance control is the same as that described in "item e3" above, so the explanation is omitted.

[0126] [f. Operational guidance control based on fire signals from fire detectors] Next, we will explain the operation guidance control when the disaster prevention receiving panel first receives a fire signal from the fire detector.

[0127] The control unit 40 of the disaster prevention receiving panel 10 receives an interrupt signal as a fire signal from the fire detector 16 via the transmission units 4210 and 4230. When the transmission units 4210 and 4230 receive an interrupt signal as a fire signal from the fire detector 16 and identify the address of the fire detector 16 that detected the fire, the control unit 40 specifies the address of a fire hydrant device 20 installed in the detection area corresponding to the detection area of ​​the fire detector 16 at the identified address, and causes the transmission units 4210 and 4230 to send a control command signal containing instruction information that confirms the fire and prompts the user to report the fire by operating a transmitter.

[0128] When the terminal control device 58 of the fire hydrant device 20 receives a control command signal from the disaster prevention receiving panel 10 that includes instruction information for operation guidance to confirm the fire for which its own address has been specified and to prompt the fire to be reported by operating the transmitter, the control unit 150 causes, for example, the transmitter operation guidance unit 96 to blink and the speaker unit 98 to output a predetermined voice message: "Beep beep beep. Please confirm the fire. If you confirm the fire, press the transmitter to report the fire."

[0129] Therefore, road users near the fire hydrant system 20 will receive an audio message from the fire hydrant system 20, confirm the fire, and press the button on the transmitter 88. The terminal control unit 58 of the fire hydrant system 20 will then transmit an interrupt signal to the disaster prevention receiving panel 10 based on the operation of the button on the transmitter 88.

[0130] The disaster prevention receiving panel 10 then detects both the fire detection by the fire detector 16 and the fire notification via a response signal that includes an interrupt signal from the fire hydrant device 20 and operation event information indicating the operation of the transmitter, i.e., switch operation information with the leading bit set to bit 1. Based on the interrupt signal already received from the fire detector 16, the panel determines that there is a fire and outputs a fire alarm from the alarm unit 45. It also controls the alarm display board equipment 30 to display, for example, a tunnel entry prohibition sign, and transmits a control command signal containing instruction information for opening the fire hydrant door 70 to the identified fire hydrant device 20 from the transmission units 4220 and 4240. The subsequent operation guidance control is the same as the control described in "items e1 to e4" already explained, so the explanation will be omitted.

[0131] [g. Operation guidance control when opening the fire hydrant door for the first time] Next, we will explain the operation instructions for when a road user first opens the fire hydrant door 70 without operating the transmitter 88.

[0132] In urgent and chaotic situations such as a fire occurring inside a tunnel, it is conceivable that road users might first attempt to open the fire hydrant door 70 in order to use the fire hose 114 stored inside, without operating the transmitter 88.

[0133] In such cases, since the operated fire hydrant device 20 does not have an address assigned to the disaster prevention receiving panel 10, the terminal control device 58 of the fire hydrant device 20 detects that the door detection switch 74 is ON due to the opening operation of the fire hydrant door 70, and sends an interrupt signal to the disaster prevention receiving panel 10, provided that it has not sent an interrupt signal.

[0134] Upon receiving an interrupt signal based on the operation to open the fire hydrant door, the disaster prevention receiving panel 10 identifies the address of the fire hydrant device 20 that sent the interrupt signal, shortens the transmission period of the polling command signal to the identified fire hydrant device 20 compared to the normal monitoring state, and transmits the polling signal. The response signal does not contain operation event information indicating the operation of the transmitter transmitted from the identified fire hydrant device 20, but does contain operation event information indicating the operation to open the fire hydrant door, i.e., the first bit information is set to bit 0 and the fourth bit information from the beginning is set to bit 1. Based on this, the panel detects that the operation to open the fire hydrant door 70 was an error and transmits a control command signal to the identified fire hydrant device 20 containing instruction information indicating that a fire has been confirmed and that the fire will be reported by operating the transmitter.

[0135] When the terminal control device 58 of the fire hydrant system 20 receives a control command signal from the disaster prevention receiving panel 10 that includes instruction information for operation guidance to check for a fire with its own address specified and to prompt fire reporting by operating the transmitter, the control unit 150 causes, for example, the transmitter operation guidance unit 96 to blink and outputs a predetermined voice message from the speaker unit 98 saying, "Beep beep beep. Check for a fire before using the fire hydrant. If a fire is confirmed, press the transmitter to report the fire."

[0136] Although opening the fire hydrant door 70 without operating the transmitter 88 is an operational error, it is not necessary to close the fire hydrant door 70 once it has been opened, so no voice message indicating an operational error with the fire hydrant door is output.

[0137] Therefore, road users who open the fire hydrant door 70 without operating the transmitter 88 will receive operational guidance from the fire hydrant system 20, confirm the fire, and press the button on the transmitter 88. The terminal control device 58, at the response timing following the receipt of a polling command signal specifying its own address, sends a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the opening of the fire hydrant door and the operation of the transmitter. Since the address of the fire hydrant system 10 that is the target of the operational guidance has already been identified, no interrupt signal is sent even if the transmitter 88 is operated.

[0138] Furthermore, the disaster prevention receiving panel 10 detects both a fire based on an interrupt signal transmitted as a fire signal from the fire detector 16 after a separate fire has been detected, and a fire alert based on the interrupt signal already received and the operation event information indicating the operation of the transmitter included in the received response signal. When it determines that there is a fire, the control unit 40 outputs a fire alarm from the alarm unit 45 and controls, for example, the alarm display board equipment 30 to display a tunnel entry prohibition sign. Since it also receives operation event information indicating the operation of opening the fire hydrant door, the subsequent operation guidance control will be the same as the control described in "items e2 to e4" already explained, and will not be explained further.

[0139] [h. Control operation of the disaster prevention receiver panel regarding operation guidance] The control operation related to the operation guidance by the control unit 40 of the disaster prevention receiver panel 10 shown in Figure 5 will be explained. In this explanation, refer to Figures 6 and 7, which are flowcharts showing the monitoring and control of the fire hydrant system by the disaster prevention receiver panel. Note that the flowchart in Figure 7 is a continuation of the flowchart in Figure 6.

[0140] When the transmission units 4210 and 4230 of the disaster prevention receiving panel 10 receive an interrupt signal as a fire signal from the fire detector 16, the control unit 40 selects the address of the fire hydrant device 20 corresponding to the detection area of ​​the fire detector 16 and sends control command signals from the transmission units 4220 and 4240 to instruct the specified fire hydrant device 20 to output an operation guide stating that a fire has been confirmed and prompting the user to report the fire by operating the transmitter (steps S1 to S3).

[0141] Next, when the control unit 40 receives an interrupt signal from the fire hydrant device 20 based on the operation of the transmitter 88 by the transmission units 4220 and 4240, it identifies the address of the fire hydrant device 20 that sent the interrupt signal (steps S4 and S5).

[0142] Next, if the control unit 40 detects an operation of the transmitter based on the operation event information indicating the operation of the transmitter included in the response signal from the identified fire hydrant device 20, it sends a control command signal from the transmission units 4220 and 4240 to instruct the identified fire hydrant device 20 to output an operation guide prompting it to open the fire hydrant door (steps S6 and S7).

[0143] Next, the control unit 40 detects the opening of the fire hydrant door based on the operation event information indicating the operation of the transmitter and the opening of the fire hydrant door included in the response signal from the identified fire hydrant device 20. Upon detection, the control unit 4220 and 4240 transmit control command signals to instruct the identified fire hydrant device 20 to output operation guidance prompting the removal of the nozzle (steps S8 and S9).

[0144] Next, the control unit 40 detects a nozzle removal operation based on operation event information indicating the operation of the transmitter, the opening of the fire hydrant door, and the removal of the nozzle, which are included in the response signal from the identified fire hydrant device 20. Upon detection of the nozzle removal operation, the control unit 4220 and 4240 transmit control command signals to the identified fire hydrant device 20, instructing it to output operation guidance prompting the opening of the fire hydrant valve opening / closing lever (steps S10, S11).

[0145] Next, based on the operation event information included in the response signal from the identified fire hydrant device 20, which indicates the operation of the transmitter, the operation of opening the fire hydrant door, the operation of removing the nozzle, and the operation of opening the fire hydrant valve opening lever, the control unit 40 detects the opening operation of the fire hydrant valve opening lever and transmits control command signals from the transmission units 4220 and 4240 to instruct the identified fire hydrant device 20 to output operation guidance prompting it to start the water discharge operation (steps S12, S13).

[0146] This completes the series of control operations performed by the control unit 40 when the fire hydrant system 20 is operated according to the correct procedure based on the fire signal received from the fire detector 16.

[0147] On the other hand, after instructing the fire hydrant device 20 in step S9 to output an operation guidance prompting the removal of the nozzle, if the control unit 40 detects the opening of the fire hydrant valve lever as a erroneous operation event without detecting the removal of the nozzle, based on the operation event information indicating the opening of the fire hydrant valve lever included in the response signal from the identified fire hydrant device 20, the control unit 40 sends control command signals to instruct the output of an operation guidance indicating that it is an erroneous operation, and also instructs the output of an operation guidance prompting the removal of the nozzle again in order to recover from the erroneous operation (steps S10, S14, S15, S9).

[0148] Furthermore, after identifying the fire hydrant device 20 that sent the interrupt signal in step S5, the control unit 40 detects the opening of the fire hydrant door as a erroneous operation event based on the operation event information indicating the opening of the fire hydrant door included in the response signal from the identified fire hydrant device 20, without detecting the operation of the transmitter. In this case, the control unit 40 sends control command signals from the transmission units 4220 and 4240 to instruct them to output operation guidance indicating that it is an erroneous operation, and also instructs them to output operation guidance to confirm the fire and to encourage reporting the fire by operating the transmitter in order to recover from the erroneous operation (steps S6, S16~S19).

[0149] Furthermore, if the transmission units 4220 and 4240 do not receive a fire signal from the fire detector 16, the control unit 40 will perform the control operations from step S5 onward (steps S1, S20, S5-S19) without performing the control operations in steps S2-4.

[0150] [i. Control operation of fire hydrant systems related to operation guidance] The control operation related to the operation guidance by the control unit 150 of the terminal control device 58 of the fire hydrant system 20 shown in Figure 4 will be explained. In this explanation, refer to Figure 8, which is a flowchart illustrating the control operation by the terminal control device of the fire hydrant system.

[0151] As shown in Figure 8, the control unit 150 of the terminal control device 58 of the fire hydrant device 20 detects an operation event, and if it has already sent an interrupt signal from the transmission unit 148 to the disaster prevention receiving panel 10, it causes the transmission units 4220 and 4240 to send a response signal to the disaster prevention receiving panel 10 that includes operation event information indicating the detected operation event (steps S21 to S23).

[0152] Meanwhile, the control unit 150 detects an operation event and, if it has not sent an interrupt signal from the transmission unit 148 to the disaster prevention receiving panel 10, it causes the control unit 150 to send an interrupt signal to the disaster prevention receiving panel 10 (steps S21, S22, S24).

[0153] Next, when the control unit 150 receives a control command signal transmitted from the disaster prevention receiving panel 10, it activates the corresponding display unit and outputs an audio message from the speaker unit 98 based on the operation guidance instruction information contained in the control command signal (steps S25, S26).

[0154] [j. Modifications of the present invention] Modifications of the disaster prevention system and fire hydrant device according to the present invention will be described. In addition to the embodiments described above, the tunnel disaster prevention system and fire hydrant device of the present invention include the following modifications.

[0155] (Monitoring of fire hydrant devices on the disaster prevention receiving panel) In the above embodiment, the control unit 40 of the disaster prevention receiving panel 10 detects operation events based on operation event information received from the fire hydrant system 20 and performs control to instruct operation guidance. In addition, the display unit 46 of the disaster prevention receiving panel 10 may also display the operating status of the fire hydrant system 10 on the screen based on the received operation event information, so that the operating status of the fire hydrant system 20 can be grasped from the disaster prevention receiving panel 10. Furthermore, the control unit 40 of the disaster prevention receiving panel 10 may store the history of operation events as history data in memory from the received operation event information, and may read the history of operation events as needed to check and analyze the operating status of the fire hydrant system 20.

[0156] (Transmission control) The above embodiment uses half-duplex communication as an example, where the disaster prevention receiving panel 10 transmits and receives voltage mode downlink signals and current mode uplink signals on the same transmission line (transmission line and common line) as R-type transmission control between the fire detector 16 and the fire hydrant device 20. However, it is not limited to this, and full-duplex communication may be used, where the downlink transmission line and the uplink transmission line (for example, the downlink transmission line, the uplink transmission line and the common line) are provided as separate transmission lines, allowing simultaneous transmission of downlink and uplink signals.

[0157] Furthermore, in half-duplex communication, when an interrupt signal is transmitted, such as when a fire is detected by the fire detector 16 or when the transmitter 88 is operated by the fire hydrant device 20, in full-duplex communication, since the downlink and uplink transmission lines are separate transmission lines, a fire signal or fire alarm signal including the self-address is transmitted as an uplink signal instead of an interrupt signal. Also, in full-duplex communication, it is not necessary to separate the downlink and uplink signals into voltage mode and current mode; both may be in the same mode, and full-duplex communication can be realized using a known transmission method.

[0158] (Operating Instructions) The above embodiment includes a guidance display unit and a speaker unit for providing guidance to encourage operation of the fire hydrant equipment, but either one of them may be provided instead.

[0159] (Inspection work) Furthermore, while the fire hydrant system 20 is subject to periodic inspections, the disaster prevention receiver panel 10 may be set to inspection mode during these inspections. One of the inspection modes may be to disable fire alarm operation and linkage to equipment other than the fire hydrant system 20, allowing for verification that correct operation guidance is output for the operation of the fire hydrant equipment of the fire hydrant system 20.

[0160] (Activity detection target) In the above embodiment, the operation of the transmitter, fire hydrant door, nozzle, and fire hydrant opening / closing lever provided on the fire hydrant device 10 is detected, and operation guidance is provided in response to the operation of these fire hydrant devices. However, the fire hydrant devices to be detected are not limited to these, and for example, the fire extinguisher 140 stored in the fire extinguisher storage section 65 of the fire hydrant device 20 and the fire extinguisher door 78 provided on the housing 60 may also be included as detection targets.

[0161] More specifically, a door detection switch is provided on the fire extinguisher door 78, similar to the fire hydrant door 70, so that the opening operation of the fire extinguisher door 78 can be detected as an operation event. Additionally, a detection switch is provided on the bottom of the fire extinguisher storage section 65 where the fire extinguisher 140 is stored, which is turned off when the fire extinguisher 140 is stored and turned on when the fire extinguisher 140 is removed, so that the removal operation of the fire extinguisher 140 can be detected as an operation event.

[0162] Furthermore, if the fire alarm receiver 10 detects that the fire extinguisher door 78 has been opened before a fire alarm is issued, it outputs instructions to confirm the fire and to prompt the user to report the fire by operating the transmitter. If the fire alarm receiver 10 detects that the fire extinguisher door 78 has been opened after a fire alarm has been issued, it outputs instructions to prompt the user to remove the fire extinguisher. If the fire extinguisher 140 is removed, it outputs instructions on how to operate the fire extinguisher.

[0163] (Detection target for misoperation) In the above embodiment, the disaster prevention receiver panel 10 detects that opening the fire hydrant valve lever 124 without removing the nozzle 120 and opening the fire hydrant door 70 before operating the transmitter 88 are incorrect operations. However, the detection of incorrect operations is not limited to these operations, and is determined by considering the equipment installed in the fire hydrant system, the operating procedures of the fire hydrant system, the designer's design philosophy, etc. For example, abnormal operations that are not expected from the correct operating procedures of the fire hydrant system, such as closing a fire hydrant door that has been opened once, or returning a nozzle that has been removed once to the nozzle holder, may also be included as targets for incorrect operation detection.
