Disaster prevention system

Abstract

This system remotely monitors and restores faulty disaster prevention receiving panels that monitor areas such as tunnels, eliminating the need for human emergency response personnel to travel to remote disaster prevention receiving panels. [Solution] The disaster prevention system consists of a higher-level station equipment 26 at the monitoring center and a disaster prevention receiving panel 10 installed on the distant tunnel side, connected via a communication network 25. The monitor device 46 of the disaster prevention receiving panel 10 displays a display operation screen 4610, which is displayed as a mirror display operation screen 9010 on the monitor device 90 of the higher-level station equipment 26 via the communication network 25. If a failure occurs in the disaster prevention receiving panel 10, a system recovery signal or system restart signal is sent to the disaster prevention receiving panel 10 via a fault recovery operation using the mirror display operation screen 9010, without having to go to the tunnel side, to perform a recovery operation or a restart operation. Before starting the fault recovery operation, the disaster prevention receiving panel 10 saves history data of the fault occurrence status, and reads and transmits the history data upon a transmission request from the higher-level station equipment 26.

Description

Technical Field

[0001] The present invention relates to a disaster prevention system that connects terminal devices such as reporting devices and detectors installed in a monitoring area to a disaster prevention receiving board to monitor abnormalities in the monitoring area.

Background Art

[0002] Conventionally, in tunnels such as exclusive motorways that serve as monitoring areas, tunnel emergency facilities have been installed to construct a tunnel disaster prevention system that protects people and vehicles from fire accidents occurring inside the tunnel.

[0003] Such tunnel emergency facilities include, as terminal devices, a fire detector for detecting a fire and reporting a fire, a manual reporting device or emergency phone for reporting a fire, a fire hydrant activation device for extinguishing a fire and preventing its spread, and an automatic valve device of a water spray facility that sprays fire extinguishing water from a water spray head to protect the inside of ducts under the road surface of the tunnel structure and the monitor passage from fire, and a duct temperature detector. A disaster prevention receiving board for monitoring and controlling the terminal devices of these emergency facilities is installed in the tunnel electrical room.

[0004] In addition, the disaster prevention receiving board is communicatively connected to upper station facilities installed remotely outside the tunnel via a dedicated external communication network. The upper station facilities are, for example, facilities installed in a road management room of a road information system that operates and manages a highway network including tunnels that are far from the tunnel, and each of the disaster prevention receiving boards installed in a plurality of tunnels is communicatively connected in a tree or star shape. And the disaster prevention receiving board can transmit the processing results associated with the monitoring and control of a fire in the tunnel to the upper station facilities via the dedicated external communication network for display (Patent Document 1).

Summary of the Invention

[0006] Incidentally, in disaster prevention systems that connect disaster prevention receiving panels installed in multiple tunnels to higher-level station equipment such as monitoring centers via a communication network, in order to reduce the human burden of system operation and management, it is required that the equipment monitoring on the tunnel side be automated, and that in the event of a failure in the disaster prevention receiving panel, personnel will go from the monitoring center or other location to the tunnel side to perform necessary recovery operations.

[0007] However, in conventional disaster prevention systems that enable remote monitoring, the processing results related to monitoring and controlling fires in tunnels are transmitted to and displayed at higher-level equipment. However, for incidents other than fires, such as malfunctions of the disaster prevention receiving panel, emergency response is basically based on human intervention on the tunnel side where the disaster prevention receiving panel is installed, making it difficult to automate equipment monitoring on the tunnel side.

[0008] The present invention aims to provide a disaster prevention system that remotely monitors and restores a disaster prevention receiving panel that monitors a monitoring area such as a tunnel, thereby eliminating the need for human emergency response personnel to travel to a distant disaster prevention receiving panel. [Means for solving the problem]

[0009] (Disaster prevention system) The present invention A disaster prevention receiver panel that connects designated terminal equipment such as notification devices and detectors installed within the monitoring area to monitor abnormalities within the monitoring area, The disaster prevention receiving panel is connected to higher-level equipment via a designated communication network, A disaster prevention system equipped with, A control unit that transmits the contents of the display operation screen shown on the disaster prevention receiver panel to a higher-level facility via a communication network to display it as a mirrored display operation screen, and transmits operation signals corresponding to the operation on the mirrored display operation screen to the disaster prevention receiver panel via the communication network to perform control corresponding to the operation signals, When a malfunction occurs in the disaster prevention receiving panel, a fault recovery unit inputs a fault recovery signal to the disaster prevention receiving panel based on the operation of the mirror display operation screen of the higher-level equipment, causing it to perform a predetermined fault recovery operation. Before the disaster recovery operation begins on the disaster prevention receiver panel, a history storage unit saves history data of the disaster occurrence state and operation state of the disaster prevention receiver panel. It is characterized by having the following features.

[0010] (System recovery) The Disaster Recovery Department is, The higher-level equipment is equipped with a recovery instruction unit, and the disaster prevention receiving panel is equipped with a recovery execution unit. If a malfunction occurs while the disaster prevention receiver panel is in operation, a system recovery signal (initialization signal) is sent from the recovery instruction unit to the recovery execution unit of the disaster prevention receiver panel based on the recovery instruction operation on the mirror display operation screen, causing the system to perform a predetermined recovery operation (initialization operation).

[0011] (Details of the recovery process) The disaster prevention receiver panel's recovery execution unit performs at least the clearing and reacquisition of the current status information in the monitoring control of the monitoring area.

[0012] (Restarting the disaster prevention receiver panel) The Disaster Recovery Department is, The higher-level equipment is equipped with a restart instruction unit, and the disaster prevention receiver panel is equipped with a restart execution unit. If the disaster prevention receiver unit stops working, a system restart signal is sent from the restart instruction unit to the disaster prevention receiver unit's restart execution unit based on the restart operation operation on the mirror display screen, thereby restarting the disaster prevention receiver unit.

[0013] (Details of the restart) The restart execution unit of the disaster prevention receiver panel is restarted by at least turning off the power to the disaster prevention receiver panel once and then turning it back on.

[0014] (Two-step restart) The restart execution unit of the disaster prevention receiver panel is: The first restart involves shutting down and then restarting the software of the computer circuit section, which is installed as the control unit of the disaster prevention receiver panel. When the failure is not resolved by the first restart, the second restart is performed by turning off the power of the disaster prevention receiver once and then turning it on again. Perform it.

[0015] (Life and death monitoring of the disaster prevention receiver) The failure recovery unit periodically transmits a predetermined operation monitoring signal to the disaster prevention receiver and determines and notifies the stop of operation of the disaster prevention receiver when the reception condition of the predetermined response signal is not satisfied.

[0016] (Time limit for the number of recovery operations) The failure recovery unit limits the number of recovery operations per predetermined time interval on the mirror display operation screen of the upper-level equipment to a predetermined number.

[0017] (Authentication operation) When the failure recovery unit performs a predetermined authentication operation and is authenticated, the failure recovery operation is permitted.

[0018] (Printing of history data) The history storage unit reads out and prints the stored history data.

[0019] (Transmission of history data) When the history storage unit receives a transmission request from the upper-level equipment, it reads out the stored history data and transmits it to the upper-level equipment.

Effect of the invention

[0020] (Effect of the disaster prevention system) The present invention relates to a disaster prevention system comprising: a disaster prevention receiving panel that monitors abnormalities in a monitoring area by connecting predetermined terminal equipment such as notification devices and detectors installed in the monitoring area; and a higher-level equipment connected to the disaster prevention receiving panel via a predetermined communication network, wherein the system includes: a control unit that transmits the contents of the display operation screen displayed on the disaster prevention receiving panel to the higher-level equipment via the communication network to display it as a mirror display operation screen, and a control unit that transmits operation signals corresponding to the operation of the mirror display operation screen to the disaster prevention receiving panel via the communication network to perform control corresponding to the operation signals; a fault recovery unit that, in the event of a failure in the disaster prevention receiving panel, inputs a fault recovery signal to the disaster prevention receiving panel based on the operation of the mirror display operation screen of the higher-level equipment to perform a predetermined fault recovery operation; and a system that, before the fault recovery operation starts in the disaster prevention receiving panel, determines the fault status of the disaster prevention receiving panel (including fault recovery) and the status of the mirror display operation (hereinafter referred to as "operation status"). The system includes a history storage unit that stores history data (which may include information on the progress (state transitions) of failure occurrence, failure recovery, and mirror display operations, as well as time information for each state transition). As a result, even if the disaster prevention receiving panel is unmanned, the monitoring content displayed on the display operation screen of the disaster prevention receiving panel is displayed as is on the mirror display operation screen of the higher-level equipment, enabling remote monitoring similar to that performed by being on-site at the disaster prevention receiving panel. Furthermore, if a failure occurs during the operation of the disaster prevention system, a failure recovery signal can be sent to the disaster prevention receiving panel by operating the mirror display operation screen of the higher-level equipment, allowing for failure recovery operations to be performed without having to go to the site. Moreover, by saving history data of the failure occurrence state and operation state of the disaster prevention receiving panel before the failure recovery operation begins on the disaster prevention receiving panel, the cause of the failure can be identified from the history data, and measures can be taken to resolve the cause of the failure.

[0021] (Effects of system recovery) Furthermore, the fault recovery unit is equipped with a recovery instruction unit on the higher-level equipment and a recovery execution unit on the disaster prevention receiver panel. When a fault occurs while the disaster prevention receiver panel is operating, the recovery instruction unit sends a system recovery signal (initialization signal) to the recovery execution unit on the disaster prevention receiver panel based on the recovery instruction operation on the mirror display operation screen. This causes the unit to perform a predetermined recovery operation (initialization operation), which at least clears and reacquires the current status information in the monitoring control of the monitoring area. Therefore, faults caused by temporary reasons such as detector malfunctions or noise can be resolved by instructing the operating disaster prevention receiver panel to perform a recovery operation based on instructions from the higher-level equipment, thereby returning the system to a normal monitoring state without the need for on-site emergency response.

[0022] (Effects of restarting the disaster prevention receiver panel) Furthermore, the fault recovery unit is equipped with a restart instruction unit in the higher-level equipment and a restart execution unit in the disaster prevention receiver panel. When the disaster prevention receiver panel stops working, based on the restart operation on the mirror display operation screen, a system restart signal is sent from the restart instruction unit to the restart execution unit in the disaster prevention receiver panel, restarting the disaster prevention receiver panel. This allows the fault to be resolved and the panel to operate normally by restarting the disaster prevention receiver panel through a power cycle. More specifically, a failure of the disaster prevention receiver panel refers to a situation where the software or hardware of the computer circuit section, which is provided as the control unit of the disaster prevention receiver panel, has stopped (frozen), or, for example, when the results of the periodic test of the detector repeatedly show abnormalities randomly, raising suspicion of internal hardware retention. In such cases, a hard reboot can be performed to restart the stopped software and return to a normal monitoring state. Here, "hard reboot" refers to the process of turning off and then turning back on the power to the disaster prevention receiver panel, including the computer.

[0023] (The effect of a two-stage restart) Furthermore, the disaster prevention receiver panel's restart execution unit performs two types of restarts: a first restart, which terminates and then restarts the software of the computer circuit section, which is provided as the control unit of the disaster prevention receiver panel; and a second restart, which, if the first restart fails or the problem is not resolved by the first restart, restarts the disaster prevention receiver panel by turning off and then on the power supply. Therefore, if the disaster prevention receiver panel stops working, the first restart is performed as a soft reboot, which restarts the software of the computer circuit section, which is provided as the control unit of the disaster prevention receiver panel, while maintaining the power supply. This allows the software to start up normally and return to a normal operating state. Here, "soft reboot" is a process that terminates and restarts the software (application) while maintaining the power supply.

[0024] Furthermore, if the first restart fails or the problem is not resolved by the first restart, a second restart can be performed: a hard reboot, which involves turning off and then on the power to the disaster prevention receiver panel. This restarts the stopped software and restores the system to a normal monitoring state. This two-stage restart process, namely a soft reboot and a hard reboot, makes it possible to more reliably restore a stopped disaster prevention receiver panel to an operational state.

[0025] (Effect of monitoring the status of the disaster prevention receiver panel) Furthermore, the fault recovery unit periodically transmits a predetermined operational monitoring signal to the disaster prevention receiver panel. If the conditions for receiving a predetermined response signal are not met, it determines that the disaster prevention receiver panel has stopped operating and issues a notification. While it is possible for personnel to manually determine if the disaster prevention receiver panel has stopped operating by monitoring the mirror display operation screen on the higher-level equipment, this places a heavy burden on the operator. Therefore, by periodically transmitting an operational monitoring signal from the higher-level equipment to automatically monitor the status of the disaster prevention receiver panel, the higher-level equipment can be quickly notified of the malfunction, and the higher-level equipment can instruct a restart, thereby restoring the stopped disaster prevention receiver panel to a normal operating state. In other words, the fault recovery unit makes it possible to resolve the malfunction without personnel having to go to the site and return to a normal monitoring state that eliminates the need for on-site emergency response.

[0026] (Effect of the time limit on the number of recovery operations) Furthermore, the fault recovery unit limits the number of recovery operations per predetermined time interval using the mirror display operation screen of the higher-level equipment. Therefore, if the fault in the disaster prevention receiver panel is not recovered even after performing recovery operations or restarts, repeating the fault recovery operations at short time intervals will increase the electrical stress on the disaster prevention receiver panel, potentially causing further failures. By setting a time limit on the number of recovery operations, it is possible to suppress the repetition of fault recovery operations beyond what is necessary.

[0027] (Effect of authentication) Furthermore, since the fault recovery unit is only permitted to perform fault recovery operations after performing a prescribed authentication procedure and being authenticated, security can be enhanced by, for example, performing an authentication procedure using an ID and password, considering the possibility that the disaster prevention receiver panel may be restarted due to unauthorized access to higher-level equipment.

[0028] (Effect of printing historical data) Furthermore, since the history storage unit reads and prints the stored history data, if a printer is installed on the disaster prevention receiver panel, the history data can be printed out, allowing it to be saved in paper form.

[0029] (Effects of sending historical data) Furthermore, when the history storage unit receives a transmission request from the higher-level equipment, it reads the stored history data and transmits it to the higher-level equipment. Therefore, after the fault in the disaster prevention receiver panel is resolved, the higher-level equipment can check the history data of the fault status of the disaster prevention receiver panel that was stored before the fault recovery operation began in the disaster prevention receiver panel, making it possible to identify the cause of the fault and take appropriate action.

[Modes for carrying out the invention]

[0031] Embodiments of the disaster prevention system according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0032] [Basic Concepts of the Embodiment] First, the basic concept of this embodiment will be explained. This embodiment generally relates to a disaster prevention system equipped with a disaster prevention receiving panel and higher-level equipment.

[0033] Here, a "disaster prevention receiving panel" is a device that connects terminal equipment installed within the monitoring area to monitor for abnormalities within that area. Furthermore, the "monitoring area" includes the area, range, or space within a structure that is subject to monitoring for abnormalities, and specifically, it is a concept that includes spaces within tunnels, etc.

[0034] Furthermore, "tunnel" refers to a tunnel that has a road through which vehicles pass, such as an expressway or a highway. Also, "terminal equipment" refers to equipment that is managed or controlled by a disaster prevention receiving panel and outputs a predetermined signal related to the abnormality to the disaster prevention receiving panel via a signal line when an abnormality occurs. The "terminal equipment" targeted in this embodiment is a concept that includes fire detectors, manual reporting devices, etc., installed as emergency equipment in tunnels.

[0035] Furthermore, "higher-level equipment" refers to equipment connected to the disaster prevention receiving panel via a designated communication network, and is installed in the road management office of the road information system that operates and manages the highway network, including tunnels.

[0036] Furthermore, the disaster prevention system of this embodiment includes a coordinated control unit, a fault recovery unit, and a history storage unit.

[0037] Here, the "cooperation control unit" is a function that transmits the contents of the display operation screen shown on the disaster prevention receiver panel to the higher-level equipment via the communication network to display it as a mirrored display operation screen, and also transmits operation signals corresponding to the operations on the mirrored display operation screen to the disaster prevention receiver panel via the communication network to perform control corresponding to the operation signals.

[0038] Furthermore, the "fault recovery unit" is a function that, in the event of a fault in the disaster prevention receiving panel, transmits a fault recovery signal to the disaster prevention receiving panel based on the operation of the mirror display operation screen of the higher-level equipment, thereby causing the panel to perform a predetermined fault recovery operation.

[0039] Furthermore, the "history storage unit" is a function that saves historical data of the fault status of the disaster prevention receiver before the disaster recovery operation of the disaster prevention receiver unit begins.

[0040] Therefore, even if the disaster prevention receiving panel is unmanned, the monitoring information displayed on the display operation screen of the disaster prevention receiving panel is displayed directly on the second screen of the higher-level equipment, enabling remote monitoring operations that are the same as if someone were physically present at the disaster prevention receiving panel.

[0041] Furthermore, if a malfunction occurs in the disaster prevention receiver panel, it is possible to input a fault recovery signal to the disaster prevention receiver panel by operating the mirror display operation screen of the higher-level equipment, thereby performing fault recovery operations remotely from the higher-level equipment without requiring personnel to go to the tunnel.

[0042] Furthermore, by saving historical data on the fault occurrence status and operation status of the disaster prevention receiver before the fault recovery operation begins on the disaster prevention receiver, it becomes possible to identify the cause of the fault from the historical data and take measures to resolve the cause of the fault.

[0043] Furthermore, the "fault recovery unit" is equipped with a recovery instruction unit in the higher-level equipment and a recovery execution unit in the disaster prevention receiving panel. When a fault occurs while the disaster prevention receiving panel is operating, the unit transmits a system recovery signal (initialization signal) from the recovery instruction unit to the recovery execution unit of the disaster prevention receiving panel based on the recovery instruction operation on the mirror display operation screen, causing the unit to perform a predetermined recovery operation (initialization operation). Here, the "recovery operation of the disaster prevention receiving panel" means at least clearing and reacquiring the current status information in the monitoring control of the monitoring area.

[0044] Therefore, if a malfunction occurs while the disaster prevention receiving panel is operating due to a temporary cause such as a terminal device malfunction or noise, the malfunction can be resolved by instructing the disaster prevention receiving panel to perform a recovery operation from the higher-level equipment, thereby returning to a normal monitoring state that does not require on-site emergency response.

[0045] Furthermore, the "fault recovery unit" is equipped with a restart instruction unit in the higher-level equipment and a restart execution unit in the disaster prevention receiver panel. When the disaster prevention receiver panel stops working, it sends a system restart signal from the restart instruction unit to the restart execution unit in the disaster prevention receiver panel based on the restart operation operation on the mirror display screen, thereby restarting the disaster prevention receiver panel. This restart process of the disaster prevention receiver panel by restoring power resolves the fault and enables it to operate normally.

[0046] More specifically, a malfunction of the disaster prevention receiving panel refers to a situation where the software or hardware of the computer circuit section, which serves as the control unit of the disaster prevention receiving panel, has stopped (froze), etc. It is possible to restart the stopped software and return to a normal monitoring state by performing a hard reboot. Here, "hard reboot" refers to the process of turning off and then turning back on the power to the disaster prevention receiving panel, including the computer.

[0047] Furthermore, "booting" refers to the startup or setup process that occurs when a computer system is powered on or after a computer system reset, from the time the basic system software, such as the monitor and operating system (OS), is loaded into main memory until user programs (applications) can be executed.

[0048] Furthermore, the restart of the disaster prevention receiver panel may be a two-stage restart consisting of a first restart and a second restart. The "first restart" is the process of shutting down and restarting the software of the computer circuit section, which is provided as the control unit of the disaster prevention receiver panel. The "second restart" is the process of turning off and then on the power to the disaster prevention receiver panel to restart the software if the first restart could not be performed, if the software did not start after the first restart, or if the problem was not resolved.

[0049] Therefore, if the disaster prevention receiver panel stops working, the first step is to perform a soft reboot, which restarts the software of the computer circuit section that serves as the control unit of the disaster prevention receiver panel, while maintaining power. This allows the software to start up normally and return the system to a normal operating state. Here, "soft reboot" is a process that terminates the software (application) once and then restarts it while maintaining power.

[0050] Furthermore, if the first restart fails, or if the software does not start or the problem is not resolved by the first restart, a second restart can be performed: a hard reboot, which involves turning off and then on the power to the disaster prevention receiver panel. This restarts the stopped software and restores the system to a normal monitoring state. This two-stage restart process, namely a soft reboot and a hard reboot, ensures that a stopped disaster prevention receiver panel can be restored to an operational state.

[0051] Furthermore, the "Fault Recovery Unit" periodically sends a predetermined operational monitoring signal from the higher-level equipment to the disaster prevention receiving panel. If the conditions for receiving a predetermined response signal are not met, it determines that the disaster prevention receiving panel has stopped operating and issues a notification. This is because while it is possible for personnel to manually determine if the disaster prevention receiving panel has stopped operating by closely monitoring the mirror display operation screen of the higher-level equipment, this places a heavy burden on the staff. By periodically sending an operational monitoring signal from the higher-level equipment to automatically monitor the status of the disaster prevention receiving panel, the higher-level equipment can be quickly notified of the panel's stoppage, and the higher-level equipment can then instruct it to restart, restoring the stopped disaster prevention receiving panel to a normal operating state. In other words, the "Fault Recovery Unit of the Higher-Level Equipment" makes it possible to resolve the malfunction without personnel having to go to the site and return to a normal monitoring state, eliminating the need for on-site emergency response.

[0052] Furthermore, the "fault recovery unit" limits the number of recovery operations performed within a predetermined time interval via the mirror display operation screen of the higher-level equipment. This is because if the fault in the disaster prevention receiver panel is not recovered even after performing recovery operations or restarts, it is anticipated that the fault recovery operations will be repeated at short time intervals. In this case, the electrical stress on the disaster prevention receiver panel will increase, potentially causing further malfunctions. In other words, by setting a time limit on the number of recovery operations using the "fault recovery unit of the higher-level equipment," it is possible to suppress the repetition of fault recovery operations beyond what is necessary.

[0053] Furthermore, the "fault recovery unit" is only permitted to perform fault recovery operations after a prescribed authentication procedure has been performed and authentication has been successful. For example, when transmitting a fault recovery signal by operating the mirror display operation screen of a higher-level device, if an authentication procedure is not required, there is a possibility that the disaster prevention receiver panel may be restarted due to unauthorized access to the higher-level device. Therefore, it is possible to enhance security by performing an authentication procedure using an ID and password, for example.

[0054] Furthermore, if a printer is installed on the disaster prevention receiver panel, the "history storage unit" can print out the history data of the disaster occurrence status of the disaster prevention receiver panel before the disaster recovery operation begins on the disaster prevention receiver panel, thereby allowing the history data to be saved in writing.

[0055] Furthermore, the "history storage unit" reads the history data stored in the disaster prevention receiver panel and transmits it to the higher-level equipment when it receives a transmission request from the higher-level equipment. Therefore, after the disaster prevention receiver panel has recovered from a malfunction, the higher-level equipment can check the history data of the malfunction status of the disaster prevention receiver panel that was saved before the malfunction recovery operation began, making it possible to identify the cause of the malfunction and take appropriate action.

[0056] In the specific embodiment described below, the "disaster prevention system" is a "tunnel disaster prevention system that monitors fires in the tunnel by connecting terminal equipment installed in the tunnel to a disaster prevention receiving panel," the "higher-level equipment" is "higher-level station equipment" connected to the disaster prevention receiving panel via a communication network, the "coordination control unit" is a function that coordinates the display and operation of the "display operation screen" on the disaster prevention receiving panel side and the "mirror display operation screen" of the higher-level equipment, and the "fault recovery unit" consists of the "recovery instruction unit and restart instruction unit" of the higher-level equipment and the "recovery execution unit and restart execution unit" of the disaster prevention receiving panel.

[0058] [a. Overview of the tunnel disaster prevention system] An overview of the fire extinguishing system according to the embodiment will be described. In this description, refer to Figure 1, which shows an overview of the fire extinguishing system.

[0059] As shown in Figure 1, an uphill tunnel 1a and a downhill tunnel 1b are constructed as tunnels for an expressway, and the uphill tunnel 1a and the downhill tunnel 1b are connected by an evacuation tunnel 2. The uphill tunnel 1a and the downhill tunnel 1b are equipped with emergency tunnel equipment such as a fire hydrant system 14 and a fire detector 16. In addition, the uphill tunnel 1a and the downhill tunnel 1b are equipped with water spray systems that spray fire-fighting water from water spray heads to protect the tunnel structure and the ducts under the road surface of the monitoring staff passage from fire, but these are not shown in the figure.

[0060] The fire hydrant devices 14 are installed along the wall of the monitoring staff passage in the longitudinal direction of the tunnel, for example, at intervals of 50 meters. The fire hydrant devices 14 are well known and house a fire hose with a water discharge nozzle and a fire extinguisher, and are also equipped with a transmitter that outputs an on / off signal and a fire pump starter. For example, four fire hydrant devices 14 form one section and are connected in parallel to the disaster prevention receiving panel 10 via a P-type signal line 11. The installation interval of the fire hydrant devices 14 is, for example, 50 meters, and the length of each section with four devices is approximately 200 meters. The P-type signal line 11 is a line that transmits and receives signals on a line-by-line basis by connecting multiple terminal devices in parallel.

[0061] Furthermore, the fire detectors 16 are installed along the longitudinal wall of the tunnel, for example, at 50-meter intervals, and are connected to the disaster prevention receiving panel 10 via an R-type signal line 12, and each is assigned a unique address. The fire detectors 16 are well-known and are equipped with two sets of fire detection units, a right eye and a left eye, so that they have detection areas in both the longitudinal upward and downward directions within the tunnel, which is the space to be monitored. The detection areas of adjacent fire detectors 16 are arranged continuously, for example, so that they overlap in a complementary manner. They detect fires by observing infrared radiation from flames associated with a fire occurring within the detection area and transmit a fire detection signal including their own address to the disaster prevention receiving panel 10. The R-type signal line 12 is a line that sends and receives signals by specifying a terminal address.

[0062] In addition to tunnel emergency equipment, the disaster prevention receiving panel 10 is also equipped with fire pump equipment 20, duct cooling pump equipment 22, ventilation equipment 28, alarm display board equipment 30, radio rebroadcasting equipment 32, television monitoring equipment 34, and lighting equipment 36, among others.

[0063] Here, the fire pump system 20 operates upon receiving a pump start signal output by the disaster prevention receiving panel 10 when it receives a fire detection signal from the fire detector 16 or a fire alarm signal from the operation of a transmitter installed in the fire hydrant system 14. The fire pump is driven by a motor to supply firefighting water to the fire hydrant system 14 in the tunnel, enabling water discharge.

[0064] The duct cooling pump system 22 receives temperature signals detected by temperature sensors installed in the duct beneath the road surface of the monitoring walkway via the disaster prevention receiving panel 10. When the temperature exceeds a predetermined threshold, it receives a pump activation signal and operates, driving a fire extinguishing pump with a motor to supply fire extinguishing water to a water spray head inside the duct, thereby cooling the inside of the duct and protecting the wiring cables. The ventilation system 28 is a system that generates ventilation flow in the longitudinal direction of the tunnel by operating jet fans installed on the ceiling side of the tunnel.

[0065] The warning display board equipment 30 is a system that displays abnormalities inside the tunnel, such as entry prohibition warnings due to fire, on an electronic display board to inform users. The radio rebroadcasting equipment 32 is a system that allows drivers and others inside the tunnel to receive information from the road administrator. The television monitoring equipment 34 is a system that allows road administrators to understand the situation inside the tunnel when checking the scale and location of a fire, the operation of water spray equipment, and guiding drivers and others to safety. The lighting equipment 36 is a system that operates and manages the lighting equipment inside the tunnel.

[0066] Furthermore, the disaster prevention receiving panel 10 is connected to a communication control unit 24 and can communicate with the higher-level station equipment 26 via a dedicated communication network 25. The higher-level station equipment 26 is equipment installed in the road management office of a road information system that operates and manages highway networks including tunnels, and connects each of the disaster prevention receiving panels installed in multiple tunnels to it in a tree-like structure, for example. The communication network 25 may be a general-purpose communication network using an internet connection.

[0067] [b. Disaster Prevention Receiving Panel] This section will explain the disaster prevention receiving panel. Refer to Figure 2, which shows the disaster prevention receiving panel, and Figure 3, which shows the functional configuration of the tunnel disaster prevention system.

[0068] (b1. Appearance of the disaster prevention receiver panel) As shown in Figure 2, the disaster prevention receiving panel 10 has a box-shaped enclosure that opens at the front and back, and a panel door 56 that can be opened and closed by operating a handle is provided on the front of the enclosure. A monitor device 46 using a liquid crystal display with a touch panel is installed on the front side of the panel door 56, and an operation display unit 50 is located below it. The monitor device 46 displays an operation screen 4610, which displays predetermined monitoring information and operation information related to tunnel disaster prevention monitoring.

[0069] (b2. Configuration of the disaster prevention receiving panel) As shown in Figure 3, the disaster prevention receiving panel 10 includes a panel control unit 40, which is a function realized, for example, by the execution of a program, and is composed of a computer circuit section equipped with a CPU, memory, various input / output ports including an AD conversion port, etc.

[0070] The computer circuit section constituting the control panel 40 performs tunnel monitoring and control by executing predetermined software. The software consists of an operating system (OS) and an application program for monitoring and control. When the power to the disaster prevention receiving panel 10 is turned on during the system startup boot process, the operating system (OS) and the application program are started and monitoring and control begins, and this operational state continues during operation.

[0071] An R-type transmission unit 42 is provided with the control panel 40. Fire detectors 16 installed in the tunnel are connected to the R-type transmission unit 42 via an R-type transmission line 12. When a fire is detected by any of the fire detectors 16, the R-type transmission unit 42 receives a fire detection signal including an address from the fire detector 16 that detected the fire.

[0072] Furthermore, a P-type transmission unit 44 is provided with the control panel 40. Transmitters installed in, for example, four fire hydrant devices 14 in a section unit installed in the tunnel are connected in parallel to the P-type transmission unit 44 via a P-type signal line 11, and fire alarm signals are received from the transmitters that are turned on.

[0073] Furthermore, the control panel 40 is equipped with a monitor device 46, an alarm unit 48 with a speaker, buzzer, and alarm indicator light, a display unit 50 with various indicator lights, an operation unit 52 with various switches, and a P-type transmission unit 54. The P-type transmission unit 54 is individually connected to the ventilation equipment 28, alarm display board equipment 30, radio rebroadcasting equipment 32, television monitoring equipment 34, lighting equipment 36, fire pump equipment 20, and cooling pump equipment 22 via P-type signal lines.

[0074] Furthermore, the control panel 40 is equipped with a control panel-side interoperation control unit 60 and a control panel-side fault recovery unit 62, which are connected to the upper-level station equipment 26 via the communication network 25 from the communication control unit 24. Correspondingly, the upper-level station equipment 26 is equipped with a communication control unit 74, an upper-level interoperation control unit 76, an upper-level fault recovery unit 78, an upper-level control unit 72, and a monitoring device 90.

[0075] The panel-side linkage control unit 60 and the upper-level linkage control unit 76 constitute the linkage control unit of the embodiment. The display contents of the display operation screen of the first monitor device 46 are transmitted to the upper-level station equipment 26 via the communication control unit 24, the communication network 25, and the communication control unit 74 to be displayed on the monitor device 90 as a mirror display operation screen. At the same time, operation signals corresponding to the operation of the mirror display operation screen of the monitor device 90 are transmitted to the disaster prevention receiving panel 10 via the communication control unit 74, the communication network 25, and the communication control unit 24 to perform the operation corresponding to the operation signal.

[0076] The upper-level fault recovery unit 78 and the panel-side fault recovery unit 62 constitute the fault recovery unit of this embodiment. When a fault occurs while the disaster prevention receiving panel 10 is in operation, a predetermined fault recovery signal is transmitted to the disaster prevention receiving panel 10 based on the fault recovery operation on the mirror display operation screen of the monitoring device 90, causing it to perform a predetermined fault recovery operation. Further details of the cooperation control unit and fault recovery unit of this embodiment will be described later.

[0077] (b3. Monitoring and control of disaster prevention receiving panel) Next, we will explain the monitoring and control performed by the control unit 40 installed in the disaster prevention receiving panel 10.

[0078] The control panel 40 performs predetermined monitoring and control based on fire-related signals from fire detectors 16 and transmitters installed in fire hydrant systems 14 located within the tunnel.

[0079] For example, when the fire alarm receiving panel 10 receives a fire detection signal containing an address from any of the fire detectors 16, or a fire alarm signal from the operation of any of the transmitters of the fire hydrant device 14, the alarm unit 48 sounds a main sound, the display unit 50 displays a representative fire, the monitor device 46 displays a fire and indicates the fire location on its display screen, and the red indicator light of the fire hydrant device 14 flashes as part of the fire alarm operation.

[0080] Furthermore, if a fire alarm is triggered by the control panel 40, it will perform the following actions: send a fire alarm signal to the higher-level station equipment 26 to trigger an alarm; ventilate the fire compartment using the ventilation equipment 28; display the fire compartment using the alarm display board equipment 30; enable drivers and others to receive information from the road administrator inside the tunnel using the radio rebroadcasting equipment 32; display the fire compartment using the television monitoring equipment 34; and illuminate the fire compartment using the lighting equipment 36.

[0081] Furthermore, the control panel 40 monitors various malfunctions that occur during operation. When a malfunction is detected, the alarm unit 48 sounds an alarm, displays a representative malfunction on the display unit 50, and controls the display operation screen of the monitor device 46 to show the malfunction and the malfunction area. At this time, the contents of the display operation screen of the monitor device 46 are transmitted to the higher-level station equipment 26, and the same malfunction and malfunction area are displayed on the mirror display operation screen of the monitor device 90, allowing the higher-level station equipment 26 to also be aware of the malfunction.

[0082] [c. Coordination and monitoring of disaster prevention receiving panels] Next, we will explain the coordinated monitoring of the disaster prevention receiving panel. For this explanation, please refer to Figure 4, which shows the display configuration of the display operation screen that functions as a display operation screen, and Figure 5, which shows a specific example of the display operation screen in Figure 4.

[0083] (c1. Configuration of the display and operation screen) As shown in Figure 4, the configuration of the display area of ​​the display operation screen 4610 displayed on the monitor device 46 of the disaster prevention receiver panel 10 is arbitrary, but for example, various information related to tunnel monitoring and control is displayed separately in the representative display section 92, symbol list 94, message display section 96, mode operation display section 98, screen expansion button display section 100, and variable display section 102.

[0084] Here, the representative display unit 92 is a display unit for performing representative monitoring of predetermined monitoring items regardless of the screen. The symbol list 94 has symbol list buttons for expanding the explanation screen of the display symbols. The message display unit 96 is an area for displaying the latest multiple pieces of information obtained from disaster prevention monitoring, for example, four pieces of information.

[0085] The mode operation display unit 98 is an area where control switches that are commonly used regardless of the screen are located. The screen expansion button display unit 100 is an area where switches for switching screens are located. Furthermore, the variable display unit 102 is an area where the display content is changed by touch operation on the screen expansion button display unit 100.

[0086] In this way, the display operation screen 4610 of the disaster prevention receiver panel 10 transmits screen information to the higher-level station equipment 26 through coordinated control of the display operation screen, and the same screen content is displayed on the mirror display operation screen 9010 of the monitor device 90.

[0087] (c2. Specific examples of display operation screens) Figure 5 shows a specific example of the display operation screen 4610. The representative display section 92 displays representative items such as panel failure, under testing, terminal equipment failure, compensation in progress, water distribution system equipment failure, water distribution system inspection in progress, switch warning, fire pump only, ○○TN upstream fire, ○○TN downstream fire, ○XTN upstream fire, and OCTN downstream fire. When no corresponding event has occurred, the background color is displayed, but when a corresponding event occurs, it is displayed in a predetermined color. For example, representative items of high importance are displayed in red, and representative items of the next highest importance are displayed in yellow. Note that "○○TN" is an abbreviation for "○○ tunnel" and "○XTN" is an abbreviation for "○X tunnel".

[0088] The message display unit 96 displays the latest monitoring information (event information), for example, four pieces of monitoring information. In this example, a warning of contamination of the fire detector, a failure of the signal converter, a fire occurring on the ○○TN upstream, and the operation of the water spray equipment on the ○○TN upstream are displayed along with time information.

[0089] The screen display unit 100 has screen display buttons for the entire tunnel, tunnel details, water distribution system, system system, faulty equipment, history, and maintenance. When any of these screen display buttons is touched, the corresponding display content is shown on the variable display unit 102.

[0090] The mode operation display unit 98 has frames for each type of control switch, divided into operation 104, fire extinguishing equipment water spray, fire pump, and fault recovery 110, with predetermined control buttons arranged within each frame.

[0091] The control buttons required for coordinated control between the disaster prevention receiving panel 10 and the higher-level station equipment 26 in this embodiment are the remote button 106 and the direct button 108 provided on operation 104. Operation 104 sets the operating rights between the disaster prevention receiving panel 10 and the higher-level station equipment 26. When the remote button 106 is touched, the operating rights are transferred to the higher-level station equipment 26, and the operation of the control switches located on the mirror display operation screen 9010 provided on the monitoring device 90 of the higher-level station equipment 26 becomes effective. Conversely, when the direct button 108 is operated, the operating rights are transferred to the disaster prevention receiving panel 10, and the operation of the control switches located on the display operation screen 4610 of the monitoring device 46 provided on the disaster prevention receiving panel 10 becomes effective.

[0092] Furthermore, the control buttons required for fault recovery processing between the disaster prevention receiving panel 10 and the higher-level station equipment 26 in this embodiment are the ID input field 112, password input field 114, system recovery button 116, and system restart button 118 provided on the fault recovery 110.

[0093] The ID input field 112 and password input field 114 are designed to enhance security when remotely operating the disaster prevention receiver panel 10 from an external source. The system recovery button 116 and system restart button 118 become operational only after successful authentication via the input of a predetermined ID and password. Note that if the communication network 25 connecting the disaster prevention receiver panel 10 and the higher-level station equipment 26 is a dedicated communication network, inputting an ID and password may be unnecessary. However, if the communication network 25 is a general-purpose communication network using the internet, authentication via ID and password is mandatory.

[0094] The system recovery button 116 is an operation button used to recover from a malfunction that occurred while the disaster prevention receiving panel 10 was in operation. When the system recovery button 116 is operated, a system recovery signal is sent to the panel control unit 40, and the malfunction recovery operation is performed.

[0095] In order to recover from such a malfunction, since the mirror display operation screen 9010, which has the same content as in Figure 5, is also displayed on the monitoring device 90 of the upper-level station equipment 26, an employee who has confirmed that a malfunction has occurred in the disaster prevention receiving panel 10 can operate the remote button 106 to obtain control, and then operate the system recovery button 116. This sends a system recovery signal to the disaster prevention receiving panel 10 via the communication network 25, and the malfunction recovery operation is performed.

[0096] The system restart button 118 is an operation button used to restart the disaster prevention receiving panel 10 if it has stopped. When the system restart button 118 is operated, a system restart signal is sent to the panel control unit 40, and the stopped disaster prevention receiving panel 10 is restarted.

[0097] To restart the stopped disaster prevention receiver panel 10, a mirror display operation screen 9010 with the same content as in Figure 5 is displayed on the monitoring device 90 of the upper station equipment 26. Upon confirming that the disaster prevention receiver panel 10 has stopped working, the staff member operates the remote button 106 to acquire control, and then operates the system restart button 118. This sends a system restart signal to the disaster prevention receiver panel 10 via the communication network 25, and the stopped disaster prevention receiver panel 10 is restarted.

[0098] Furthermore, there are two methods for restarting the stopped disaster prevention receiver panel 10: a soft reboot (first reboot), which involves maintaining power and then terminating the software of the computer circuit section constituting the panel control unit 40 before restarting it; and a hard reboot (second reboot), which involves cutting off and then restoring power to the computer circuit section constituting the panel control unit 40. However, the basic method is a hard reboot, which involves cutting off and then restoring power. Alternatively, a two-stage restart is also acceptable, in which a soft reboot is performed first, and only if the soft reboot fails to start the system is a hard reboot performed.

[0099] [d. Coordinated control function between the disaster prevention receiving panel and the higher-level station equipment] Next, the functional configuration of the coordinated control between the disaster prevention receiving panel and the higher-level station equipment will be described. In this description, refer to Figure 6, which shows the functional configuration of the coordinated control unit and the fault recovery unit of the embodiment.

[0100] (d1. Coordination between display and operation of the display operation screen) As shown in Figure 6, a panel-side interoperation control unit 60 and a panel-side fault recovery unit 62 are provided between the panel control unit 40 and the communication control unit 24 of the disaster prevention receiving panel 10. The panel-side fault recovery unit 62 is equipped with a recovery execution unit 64 and a restart execution unit 66. Although the communication control unit 24 is located inside the disaster prevention receiving panel 10 in Figure 6, it may also be located outside the disaster prevention receiving panel 10, as shown in Figures 1 and 3.

[0101] Meanwhile, between the upper control unit 72 and the communication control unit 74 of the upper station equipment 26, an upper-side cooperation control unit 76 and an upper-side fault recovery unit 78 are provided, and the upper-side fault recovery unit 78 is provided with a recovery instruction unit 80 and a restart instruction unit 82.

[0102] The control panel-side interoperation control unit 60 and the higher-level interoperation control unit 76 are connected by communication via the communication control unit 24, the communication network 25, and the communication control unit 74. The disaster prevention receiving panel 10 transmits screen information of, for example, the display operation screen 4610 shown in Figure 5, which is displayed on the monitoring device 46, to the higher-level station equipment 26, and displays a mirrored display operation screen 9010 with the same content on the monitoring device 90.

[0103] Therefore, personnel at the higher-level station equipment 26 can check the status of monitoring and control by the disaster prevention monitoring panel 10 by simply watching the mirror display operation screen 9010 without having to go to the tunnel side. It is also possible to connect the monitor device 46 directly to the panel-side linkage control unit 60 and transmit the screen information of the display operation screen 4610 to the higher-level station equipment 26 to display the same content on the mirror display operation screen 9010.

[0104] (d2. Disaster Recovery Department) Furthermore, the recovery instruction unit 80 of the upper-level station equipment 26 and the recovery execution unit 64 of the disaster prevention receiving panel 10 constitute the transmitting and receiving sides of a fault recovery unit that performs a predetermined recovery operation (initialization operation) when a fault occurs while the disaster prevention receiving panel 10 is in operation. In this case, the recovery instruction unit 80 transmits a system recovery signal (initialization signal) from the recovery instruction unit 80 to the recovery execution unit 64 of the disaster prevention receiving panel 10 based on the recovery instruction operation on the mirror display operation screen 9010, causing the predetermined recovery operation (initialization operation) to be performed.

[0105] Furthermore, the restart instruction unit 82 of the upper-level station equipment 26 and the restart execution unit 66 of the disaster prevention receiving panel 10 constitute the transmitting and receiving side for restarting the panel control unit 40 of the disaster prevention receiving panel 10 when the panel control unit 40 of the disaster prevention receiving panel 10 stops.

[0106] Since the restart of the control panel 40 by the restart execution unit 66 is a process that involves turning the power off and then on again, a power switch 70 is provided on the power line from the power supply unit 68 to the control panel 40. When a system restart signal is received from the upper station equipment 26, the power switch 70 is turned off to cut off the power supply to the control panel 40, and then the power switch 70 is turned on to supply power to the control panel 40 and restart it.

[0107] (d3.2-stage restart) Furthermore, in another embodiment of the restart execution unit 66, when it receives a system restart signal from the higher-level station equipment 26, it may have a function to sequentially perform a first restart by soft reboot and a second restart by hard reboot. In this case, when the restart execution unit 66 receives a system restart signal from the higher-level station equipment 26, it instructs the computer circuit section that constitutes the functions of the panel control unit 40 to perform a soft reboot, and restarts the software after it has been terminated once. If the system does not restart with a soft reboot (the problem is not resolved), it instructs the computer circuit section to perform a hard reboot, and restarts the panel control unit 40 by cutting off and then turning on the power supply to it once.

[0108] (d4, Monitoring the status of the disaster prevention receiver panel) Next, the status monitoring of the disaster prevention monitoring panel will be explained. The restart instruction unit 82 of the higher-level equipment 26 periodically transmits a predetermined operation monitoring signal to the disaster prevention receiving panel 10, and has a status monitoring function that determines and notifies that the disaster prevention receiving panel 10 has stopped operating if the conditions for receiving a predetermined response signal are not met.

[0109] The operation monitoring signal transmitted from the restart instruction unit 82 is received by the restart execution unit 66 of the disaster prevention receiving panel 10, which causes the panel control unit 40 to execute a predetermined monitoring process, such as a test monitoring application to check the operation of the computer circuit section constituting the panel control unit 40. If the monitoring application completes successfully, the restart execution unit 66 sends a response signal to the higher-level station equipment 26, but does not send a response signal if it does not complete successfully.

[0110] The restart instruction unit 82 of the higher-level equipment 26 performs control to determine and notify that the disaster prevention receiving panel 10 has stopped operating if it has transmitted an operation monitoring signal but has not received a response signal within a predetermined time, and has not received a response signal for a predetermined number of consecutive times.

[0111] Therefore, while it is possible for a human to determine if the disaster prevention receiving panel 10 is inoperable by monitoring the mirror display operation screen 9010 on the higher-level equipment 26, this places a heavy burden on the human operator. As a result, the higher-level equipment 26 periodically sends an operational monitoring signal to automatically monitor the status of the disaster prevention receiving panel 10. When the higher-level equipment 26 determines that the disaster prevention receiving panel 10 is inoperable, it promptly notifies the operator and instructs the operator to restart the disaster prevention receiving panel 10, thereby restoring the inoperable disaster prevention receiving panel 10 to a normal operating state. This makes it possible to resolve the inoperability of the disaster prevention receiving panel 10 and return to normal monitoring without requiring personnel to go to the site.

[0112] (d5. Time limit on the number of recovery operations) Next, the time limit on the number of recovery operations will be explained. The upper-level fault recovery unit 78 of the upper-level equipment 26 limits the number of recovery operations per predetermined time interval by the recovery instruction unit 80 and the restart instruction unit 82 to a predetermined number. The number of recovery operations to be limited is arbitrary, but for example, it may be limited to a predetermined number of 10 or fewer operations per day, for example, up to 5 operations.

[0113] If the recovery instruction unit 80 or the restart instruction unit 82 repeatedly performs fault recovery operations at short time intervals, the electrical stress applied to the disaster prevention receiving panel 10 will increase, potentially causing further malfunctions. Therefore, by setting a time limit on the number of recovery operations, it is possible to suppress the repetition of fault recovery operations beyond what is necessary.

[0114] (d6. Saving historical data) Furthermore, the panel-side fault recovery unit 62 of the disaster prevention receiver panel 10 is equipped with a history storage function that writes and saves history data of the fault occurrence state and operation state of the disaster prevention receiver panel 10 to memory before the panel control unit 40 starts the fault recovery operation. If the disaster prevention receiver panel 10 is equipped with a printer, the saved history data may be read and printed out.

[0115] The history data stored in the disaster prevention receiver panel 10 can be accessed and read from the upper control unit 72 of the upper station equipment 26. By checking the history data, it is possible to identify the cause of the failure and take appropriate action.

[0116] [e. Disaster recovery operation of the disaster prevention receiver panel] Next, the fault recovery operation of the disaster prevention receiving panel will be explained. In this explanation, please refer to Figure 7, which is a time chart showing the fault recovery operation when the disaster prevention receiving panel stops working, and Figure 8, which shows a simplified display operation screen of the disaster prevention receiving panel and a mirror display operation screen of the higher-level station equipment that enables fault recovery operations when the disaster prevention receiving panel stops working. Note that the fault recovery operation of the disaster prevention receiving panel is performed according to the functional configuration shown in Figure 6.

[0117] As shown in Figure 7, when the disaster prevention monitoring panel 10 is operating normally, monitoring information is displayed on the display operation screen 4610 of the monitor device 46 installed on the disaster prevention receiving panel 10. The contents of the display operation screen 4610 are transmitted to the higher-level station equipment 26 by the panel linkage control unit 60, received by the higher-level linkage control unit 76 installed on the higher-level station equipment 26, and the same contents are displayed on the mirror display operation screen 9010 of the monitor device 90 (steps S1, S2).

[0118] If a malfunction occurs while the disaster prevention receiving panel 10 is in operation and the malfunction is displayed on the display operation screen 4610 (step S3), the same malfunction will be displayed on the mirror display operation screen 9010 of the higher-level station equipment 26. If an employee of the higher-level station equipment 26 confirms the malfunction of the disaster prevention receiving panel 10 from the display on the mirror display operation screen 9010 (Yes in step S4), they will acquire control of the higher-level station equipment 26 by operating the remote button 106 on the mirror display operation screen 9010, as shown in Figure 8. Subsequently, the employee will operate the system recovery button 116, which will send a recovery signal from the recovery instruction unit 80 to the disaster prevention receiving panel 10 (step S5).

[0119] Upon receiving a recovery signal from the higher-level station equipment 26, the recovery execution unit 64 of the disaster prevention receiving panel 10 instructs the panel control unit 40 to save history data prior to the recovery process. The panel control unit 40 then saves history data indicating the state of the disaster prevention receiving panel 10, including the fault currently occurring, to memory (step S6). Subsequently, the recovery execution unit 64 instructs the panel control unit 40 to perform a recovery operation, and the panel control unit 40 performs a predetermined recovery operation for the fault that has occurred (step S7).

[0120] Here, the recovery operation by the control panel 40 is optional, but for example, it may clear and reacquire current information, including the occurrence of a fault. In this case, if the fault that occurred was temporary due to noise or the like, the fault display is restored and the system returns to the normal monitoring state, the recovery execution unit 64 transmits a response signal based on the successful completion of the recovery operation to the higher-level station equipment 26, and the mirror display operation screen 9010 displays that the system has been successfully restored.

[0121] In contrast, if the disaster prevention receiving panel 10 has stopped operating due to a malfunction, the panel control unit 40 will not perform the recovery operation even if it receives a recovery instruction from the higher-level station equipment 26, and the higher-level station equipment 26 will not receive a response signal indicating normal recovery, and will report no response (Yes in step S8).

[0122] Therefore, the person who performed the recovery operation operates the system restart button 118 on the mirror display operation screen 9010 to activate the restart instruction unit 82 as the next fault recovery operation for the stopped control panel 40.

[0123] If the restart instruction unit 82 is configured with the aforementioned two-stage restart process, then based on the operation of the system restart button 118, a first restart signal is transmitted to the disaster prevention receiving panel 10 (step S9).

[0124] Upon receiving a first restart signal from the higher-level station equipment 26, the restart execution unit 66 of the disaster prevention receiving panel 10 instructs the panel control unit 40 to retain history data prior to the second restart operation. The panel control unit 40 then saves history data in memory, which includes the faults and operations occurring at that time, indicating the state of the disaster prevention receiving panel 10 (step S10). However, since the panel control unit 40 is stopped due to a fault, depending on the severity of the fault, it may not be possible to save the history data.

[0125] Next, the restart execution unit 66 instructs the panel control unit 40 to perform a first restart operation, and the panel control unit 40, while keeping the power switch 70 ON, performs a first restart (soft reboot) in which it terminates and then restarts the software of the computer circuit section that constitutes itself (step S11).

[0126] By shutting down and then restarting the software of the computer circuit section that constitutes the control panel 40, if the software starts up and operates normally, it returns to the normal monitoring state, and the restart execution unit 66 sends a response signal based on the successful completion of the restart to the upper station equipment 26, which displays a normal recovery on the mirror display operation screen 9010.

[0127] In contrast, if the control panel 40 remains inoperable even after the first restart (soft reboot), the higher-level station equipment 26 will not receive a response signal indicating normal recovery, and it will be determined that there is no response (Yes in step S12). For this reason, the restart instruction unit 82 transmits a second restart signal to the disaster prevention receiving panel 10.

[0128] Upon receiving a second restart signal from the higher-level station equipment 26, the restart execution unit 66 of the disaster prevention receiving panel 10 instructs the panel control unit 40 to retain history data prior to the second restart operation. The panel control unit 40 then saves history data indicating the state of the disaster prevention receiving panel 10, including any malfunctions occurring at that time, to memory (step S14). However, since the panel control unit 40 is shut down due to a malfunction, it may not be possible to save history data depending on the severity of the malfunction.

[0129] Next, the restart execution unit 66 performs a second restart operation on the panel control unit 40 by turning off the power switch 70 to cut off the power to the panel control unit 40, and then turning on the power switch 70 to supply power and restart the panel control unit 40 (step S15).

[0130] When the control panel 40 is restarted (hard reboot) for the second time, and the control panel 40 starts up normally and returns to the normal monitoring state and the restart is completed (step S16), the restart execution unit 66 sends a response signal to the upper station equipment 26 based on the successful completion of the restart, the restart instruction unit 82 determines that there is a response and notifies the system by displaying that there is a response on the mirror display operation screen 9010 (step S17), and the display operation screen 4610 of the disaster prevention receiving panel 10 is displayed on the mirror display operation screen 9010 of the upper station equipment 26 and coordinated control is resumed (steps S18, S19).

[0131] Furthermore, although the restart instruction unit 82 of the upper station equipment 26 is shown as an example of operation with a two-stage restart, the first restart (soft reboot) may be omitted and only the second restart (hard reboot) may be performed. In this case, the panel control unit 40 is restarted by turning the power switch 70 on and off with a system restart signal, which turns the power off and then on again.

[0132] [f. Variations of the present invention] Modifications of the disaster prevention system according to the present invention will now be described. In addition to the embodiments described above, the disaster prevention system of the present invention includes the following modifications.

[0133] (Disaster recovery) In the above embodiment, when a malfunction occurs while the disaster prevention receiving panel is in operation, a system recovery signal is sent from the higher-level station equipment to recover from the malfunction. However, if a malfunction occurs while a fire alarm is being issued by the disaster prevention receiving panel, an interlock function that prohibits recovery operations from the higher-level station equipment can be provided to prevent the fire alarm from being canceled by the recovery operation of the disaster prevention receiving panel.

[0134] (Saving historical data) In the above embodiment, history data is saved prior to the recovery or restart operation of the control unit of the disaster prevention receiver panel. However, when a restart operation is performed, the control unit is stopped, and depending on the state of the shutdown (for example, when not only the application program for monitoring and control but also the OS is stopped), it may not be possible to execute the process of saving history data. Therefore, the control unit may perform a control that updates the monitoring and control history data by writing it to memory at predetermined time intervals while it is running. As a result, when the disaster prevention receiver panel stops working, the history data from immediately before the shutdown is saved in memory, and it becomes possible to investigate the cause of the shutdown from the history data.

[0135] (Disaster prevention system) Although the above embodiment uses a tunnel disaster prevention system as an example, the present invention is not limited thereto and can be applied to, for example, automatic fire alarm systems and water-type sprinkler fire extinguishing systems. For example, in the case of automatic fire alarm systems and water-type sprinkler fire extinguishing systems, a disaster prevention system in which a server as a higher-level facility is connected to a fire receiving panel or monitoring control panel via a predetermined communication network can be provided with the cooperation control unit, fault recovery unit and history storage unit shown in the above embodiment.

[0136] (History storage section) The history storage unit in the above embodiment may store one or two of the following: the fault occurrence status, operation status, and history data of the disaster prevention receiver panel. Furthermore, it may print or transmit one or all of the stored history data of the fault occurrence status and operation status. In addition to the fault occurrence status of the disaster prevention receiver panel, it may also include, for example, fault occurrence and recovery status related to terminal equipment or signal lines.
