Description

[Technical Field]

[0001] The present technology relates to a technology for a disaster prevention control device that controls disaster prevention equipment installed in a tunnel. [Background technology]

[0002] Generally, tunnels that allow vehicles and people to pass through are equipped with various types of disaster prevention equipment to protect people from disasters such as accidents and fires that occur within the tunnel (see, for example, Patent Document 1 below). In addition, a disaster prevention control device is installed in the road management office to receive signals from each piece of disaster prevention equipment and control each piece of disaster prevention equipment.

[0003] Disaster prevention equipment includes, for example, push-button manual reporting devices that allow people to manually report a disaster when it occurs, fire detection devices that detect fires, fire extinguishing devices that extinguish fires, and warning signs that warn vehicle drivers of an upcoming disaster.

[0004] The disaster prevention control device installed in the road management office is equipped with a display unit that displays images for the administrator to monitor the situation inside the tunnel, and an operation unit that allows the administrator to manually control the disaster prevention equipment.

[0005] For example, when a disaster is notified to the disaster prevention control device by a signal from a manual notification device or a fire detection device, the disaster prevention control device generates an alarm sound and displays the location of the disaster on the display unit. The manager visually checks the information on the screen, and then, for example, operates the operation unit to display words such as "accident occurred" on the alarm display board. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2022-39344 Summary of the Invention [Problem to be solved by the invention]

[0007] Conventionally, in order for a manager to check the occurrence of a disaster in a tunnel and control the disaster prevention equipment, the manager had to go to the front of the disaster prevention control device, view the image displayed on the display unit, and perform any control using the operation unit. Therefore, there is a problem that the manager has to bear the burden of time and effort due to the travel.

[0008] In light of the above circumstances, the purpose of this technology is to provide a technology that allows administrators to check the status of disasters occurring within tunnels and control disaster prevention equipment without burdening them with the time and effort of traveling. [Means for solving the problem]

[0009] A disaster prevention control device according to the present technology includes a display unit, an operation unit, and a control unit. The display unit displays an image for the administrator to visually monitor the occurrence of a disaster in the tunnel. The operation unit is a part that allows the manager to manually control the disaster prevention equipment installed in the tunnel. The control unit performs a display process that generates the image and displays it on the screen, a control process that controls the disaster prevention equipment based on an input signal from the operation unit, and a web server process that generates a web image on the network for the administrator to monitor the occurrence of a disaster within the tunnel and control the disaster prevention equipment, and transmits information about the web image to a terminal device via a network line.

[0010] With this technology, web images are sent to the terminal device, allowing the administrator to check the status of any disasters occurring within the tunnel by viewing the web images displayed on the terminal screen, and to control disaster prevention equipment by operating the web images, thereby preventing the administrator from having to spend time and effort traveling.

[0011] In the above-mentioned disaster prevention control device, the control unit may control the disaster prevention equipment according to a predetermined priority when there is a conflict between the administrator's control of the disaster prevention equipment via the operation unit and the administrator's control of the disaster prevention equipment via the web image.

[0012] This makes it possible to appropriately respond to a conflict between the administrator's control of the disaster prevention equipment via the operation unit and the administrator's control of the disaster prevention equipment via the web image.

[0013] In the disaster prevention control device, the control unit may prioritize control of the disaster prevention equipment by the administrator via the operation unit over control of the disaster prevention equipment by the administrator via the web image.

[0014] In general, control of disaster prevention equipment via an operation unit by a manager (at the road management office, i.e., always at the site) is likely to have a higher priority than control of disaster prevention equipment via a web image by a manager (who may not be at the site). Therefore, by controlling disaster prevention equipment with such a priority, it is possible to respond more appropriately to the above collision.

[0015] In the above-mentioned disaster prevention control device, the web image has multiple screens including a monitoring screen for the manager to monitor the occurrence of disasters within the tunnel, and a control screen for the manager to control the disaster prevention equipment, and the multiple screens may be switchable.

[0016] This improves the operability on the web image.

[0017] In the disaster prevention control device, the disaster prevention equipment may include an alarm display board, and the control screen may include an alarm display board control screen for controlling the alarm display board.

[0018] This allows the administrator to control the warning display board by operating it on a web image.

[0019] In the disaster prevention control device, the control screen may include a circuit test control screen for the manager to perform a circuit test in the disaster prevention equipment.

[0020] This allows the administrator to perform circuit tests by operating on a web image.

[0021] In the disaster prevention control device, the plurality of screens may include a history screen relating to a history of the disaster prevention equipment.

[0022] A disaster prevention control system according to the present technology includes a disaster prevention control device and a terminal device. The disaster prevention control device has a display unit, an operation unit, and a control unit. The display unit displays an image for the administrator to visually monitor the occurrence of a disaster in the tunnel. The operation unit is a part that allows the manager to manually control the disaster prevention equipment installed in the tunnel. The control unit performs a display process that generates the image and displays it on the screen, a control process that controls the disaster prevention equipment based on an input signal from the operation unit, and a web server process that generates a web image on the network for the administrator to monitor the occurrence of a disaster within the tunnel and control the disaster prevention equipment, and transmits information about the web image to a terminal device via a network line.

[0023] The control method according to the present technology includes a display process for generating an image for a manager to visually monitor the occurrence of a disaster in a tunnel and displaying the image on a screen of a display unit in a disaster prevention control device; a control process for controlling the disaster prevention equipment installed in the tunnel based on an input signal from an operation unit of the disaster prevention control device for the manager to manually control the disaster prevention equipment; The administrator monitors the occurrence of disasters within the tunnel on the network, generates web images for controlling the disaster prevention equipment, and executes web server processing to transmit information about the web images to terminal devices via a network line. [Effects of the Invention]

[0024] As described above, this technology provides a technique that allows administrators to check the occurrence of disasters within tunnels and control disaster prevention equipment without burdening them with the time and effort of traveling. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, embodiments of the present technology will be described with reference to the drawings.

[0027] First Embodiment <Overall structure and structure of each part> 1 is a diagram showing a disaster prevention control system 100 according to an embodiment of the present technology. As shown in FIG. 1, the disaster prevention control system 100 according to the present technology includes a disaster prevention facility 2, a disaster prevention control device 10 (also referred to as a receiving controller), and a terminal device 20.

[0028] Disaster prevention equipment 2 is installed in tunnel 1, which is passable by vehicles such as automobiles (and / or people). Examples of disaster prevention equipment 2 include a push-button manual reporting device 2c that allows a person to manually report the occurrence of a disaster in the event of a disaster, an emergency telephone, a fire detection device that detects fires, and a fire extinguishing device that extinguishes fires. Examples of disaster prevention equipment 2 include warning signs 2a and 2b that warn automobile drivers of the occurrence of a disaster, an imaging device that captures images inside tunnel 1, a ventilation device that ventilates tunnel 1, lighting equipment that drives each lighting device installed in tunnel 1, and a power storage device that supplies power to each device.

[0029] In Figure 1, examples of disaster prevention equipment 2 are shown as two warning display boards 2a and 2b installed near the entrance / exit of tunnel 1, and multiple push-button manual reporting devices 2c installed at predetermined intervals within tunnel 1.

[0030] A control device 3 (TMC: Tunnel Master Control unit) is installed near the warning display board 2a (the TMC 3 may be built into the warning display board 2a). A sub-control device 4 (TSC: Tunnel Sub Control unit) is installed near the warning display board 2b (the TSC 4 may be built into the warning display board 2b).

[0031] The TMC 3 and the TSC 4 are connected to each disaster prevention equipment 2 via an analog line or a digital line (such as an IP (Internet Protocol) line). The TMC 3 and the TSC 4 are configured to be able to communicate with each other, and are capable of controlling each disaster prevention equipment 2 in an integrated manner.

[0032] The TMC 3 and the TSC 4 receive signals from each disaster prevention equipment 2, and thereby automatically monitor the occurrence of a disaster (whether or not a disaster has occurred, the location of the disaster, etc.) and whether or not the disaster prevention equipment 2 has malfunctioned.

[0033] For example, the TMC 3 and the TSC 4 monitor the occurrence of a disaster (whether or not a disaster has occurred, the location of the disaster, etc.) by monitoring the presence or absence of signals from the push-button manual reporting device 2c, emergency telephones, and fire detection devices. Also, for example, the TMC 3 and the TSC 4 monitor the presence or absence of malfunctions in each of the disaster prevention equipment 2 by receiving signals from the manual reporting device 2c, emergency telephones, fire detection devices, fire extinguishing devices, warning display boards 2a and 2b, imaging devices, ventilation equipment, lighting equipment, power storage equipment, etc.

[0034] Furthermore, TMC 3 and TSC 4 automatically control the disaster prevention equipment 2 based on the automatic monitoring process. For example, when TMC 3 and TSC 4 receive a signal from the manual notification device 2c or a fire detection device, they execute processes such as automatically activating a fire extinguishing device, a ventilation device, etc., and displaying predetermined characters on the alarm display boards 2a and 2b.

[0035] Information on automatic monitoring and automatic control by the TMC 3 and TSC 4 is transmitted to the disaster prevention control device 10.

[0036] The disaster prevention control device 10 is installed in the road management office 3. The disaster prevention control device 10 is configured to be able to communicate with the TMC 3 via a digital line or the like.

[0037] The disaster prevention control device 10 is also configured to be able to communicate with each terminal device 20 via a network line (Internet line), and generates web image information in response to a request from each terminal device and transmits it to each terminal device 20 (details will be described later). The disaster prevention control device 10 and each terminal device 20 are typically connected via a VPN (Virtual Private Network).

[0038] In the example shown in Figure 1, the disaster prevention control device 10 is connected to each disaster prevention equipment 2 (TMC3) installed in one tunnel 1, but the disaster prevention control device 10 may also be connected to each disaster prevention equipment 2 (TMC3) installed in two or more tunnels 1.

[0039] The terminal devices 20 are various types of user terminals such as desktop PCs (Personal Computers), laptop PCs, tablet PCs, mobile phones (including smartphones), etc. The number of terminal devices 20 is not particularly limited.

[0040] In the example shown in FIG. 1, examples of the terminal device 20 include a desktop PC 20a (Personal Computer) installed in the road management office 3 and a laptop PC 20b placed in the manager's home.

[0041] [Disaster prevention control device 10] Fig. 2 is a block diagram showing the internal configuration of the disaster prevention control device 10. As shown in Fig. 2, the disaster prevention control device 10 includes a control unit 11, a display unit 12, an operation unit 13, a storage unit 14, a communication unit 15, and an alarm generation unit 16.

[0042] The display unit 12 is composed of an LCD display or the like, and displays images that allow the manager to visually monitor the occurrence of disasters within the tunnel 1 (whether or not a disaster has occurred, where it has occurred, etc.) according to the control of the control unit 11.

[0043] The operation unit 13 is a part that allows the administrator to manually control the disaster prevention equipment 2 installed in the tunnel 1. The operation unit 13 is composed of, for example, a push button or a touch sensor installed on the display unit 12. The operation unit 13 detects various operations input by the administrator and outputs them to the control unit 11.

[0044] The storage unit 14 includes a non-volatile memory that stores various programs and various data required for processing by the control unit 11, and a volatile memory that is used as a work area for the control unit 11.

[0045] The communication unit 15 is configured to be able to communicate with the TMC 3 via a digital line or the like. The disaster prevention control device 10 is also configured to be able to communicate with each terminal device 20 via a network line.

[0046] The alarm generating unit 16 is composed of a buzzer, a lamp, etc. When a report is made by the manual reporting device 2c or an emergency telephone, when a fire is detected by the fire detection device, when there is a malfunction in the disaster prevention equipment 2, etc., the alarm generating unit 16 notifies the manager of an emergency by sounding a buzzer or lighting a lamp, etc.

[0047] The control unit 11 executes various calculations based on various programs stored in the storage unit 14 and controls each unit of the disaster prevention control device 10 in an integrated manner.

[0048] The control unit 11 is realized by hardware or a combination of hardware and software. The hardware is configured as part or all of the control unit 11, and examples of this hardware include a CPU (Central Processing Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or a combination of two or more of these. This also applies to the control unit 21 of the terminal device 20.

[0049] In this embodiment, the control unit 11 of the disaster prevention control device 10 performs the following three main processes (1) to (3).

[0050] (1) Image display processing on the display unit 12 In the image display process, for example, an image is displayed that shows the administrator the occurrence status of a disaster (whether or not a disaster has occurred, the location of the disaster, etc.), whether or not there is a malfunction in the disaster prevention equipment 2, which disaster prevention equipment 2 has malfunctioned, etc. This image is generated based on, for example, information from automatic monitoring by the TMC 3 and the TSC 4.

[0051] Furthermore, in the image display process, for example, an image is displayed that allows the administrator to manually (via the operation unit 13) control the disaster prevention equipment 2. Examples of such images include an image for determining the characters to be displayed on the alarm display boards 2a and 2b, an image for manually operating a fire extinguishing device, a ventilation device, etc., an image for executing a circuit test in the disaster prevention equipment 2, etc.

[0052] Furthermore, in the image display process, an image relating to the history of the disaster prevention equipment 2 is displayed. Also, for example, an image captured by an imaging device is displayed on the screen.

[0053] (2) Control processing The control process is a process in which, when there is manual input from the administrator via the operation unit 13 of the disaster prevention control device 10, and when there is manual input from the administrator via the operation unit 23 of the terminal device 20, commands are issued to the TMC 3 and the TSC 4 based on this input, and the disaster prevention equipment 2 is controlled.

[0054] For example, when an instruction is given by an administrator via the operation unit 13 of the disaster prevention control device 10, the disaster prevention control device 10 issues commands to the TMC 3 and the TSC 4 based on this instruction, and performs processes such as displaying specified characters on the alarm display boards 2a and 2b, activating fire extinguishing devices, ventilation devices, etc., and performing circuit tests in the disaster prevention equipment 2.

[0055] Furthermore, for example, when an instruction is given by the administrator via the operation unit 13 of the terminal device 20, the control device issues commands to the TMC 3 and the TSC 4 based on this instruction, and performs processes such as displaying specified characters on the alarm display boards 2a and 2b and performing a circuit test on the disaster prevention equipment 2.

[0056] (3) Web server processing The web server process is a process in which the disaster prevention control device 10 generates a web image and transmits it to the terminal device 20 in response to a request from the terminal device 20. This web image is an image that allows an administrator on the network to monitor the occurrence of a disaster in the tunnel 1 (whether a disaster has occurred, where the disaster has occurred, etc.) and to control the disaster prevention equipment 2. The web image will be described in detail later.

[0057] [Terminal device 20] 3 is a block diagram showing the internal configuration of the terminal device 20. As shown in FIG. 3, the terminal device 20 includes a control unit 21, a display unit 22, an operation unit 23, a storage unit 24, and a communication unit 25.

[0058] The display unit 22 is configured with a liquid crystal display or the like, and displays various images, including web images, on the screen in accordance with the control of the control unit 21.

[0059] The operation unit 23 is configured by, for example, a keyboard, a mouse, a press-type button, a touch sensor provided on the display unit 22, etc. The operation unit 23 detects various operations input by the administrator and outputs them to the control unit 21.

[0060] The storage unit 24 includes a non-volatile memory that stores various programs and various data required for processing by the control unit 21, and a volatile memory that is used as a work area for the control unit 21.

[0061] The communication unit 25 is configured to be able to communicate with the disaster prevention control device 10 via a network line (Internet line).

[0062] The control unit 21 executes various calculations based on various programs stored in the storage unit 24 and controls each unit of the terminal device 20 in an integrated manner.

[0063] [web image] Fig. 4 is a transition diagram of a web image displayed on the display unit 12 of the terminal device 20. As shown in Fig. 4, the web image has a plurality of switchable screens. The plurality of screens include a facility point selection screen, a monitoring screen, a control screen (including a control selection screen, an alarm display panel control screen, a circuit test control screen, a control confirmation screen, and a control target selection screen), a maintenance screen, and a history screen.

[0064] "Facility location selection screen" The facility point selection screen is a screen for the administrator to decide which tunnel 1 to select from multiple tunnels 1 (facility points). For example, when the administrator selects one tunnel 1 from multiple tunnels 1 (facility points), the screen switches to the monitoring screen corresponding to the selected tunnel 1.

[0065] When an emergency occurs (for example, when a report is made by the manual reporting device 2c or an emergency telephone, when a fire is detected by the fire detection device, when a failure occurs in the disaster prevention equipment 2, or when an alarm is issued by the alarm issuing unit 16), the tunnel 1 in which the emergency occurred may be highlighted (for example, by flashing, changing color, etc.). This highlighting allows the administrator to easily recognize in which tunnel 1 the emergency occurred.

[0066] The facility location selection screen can be switched to a maintenance screen by operation.

[0067] "Monitoring screen" 5 is a diagram showing an example of a monitoring screen. The monitoring screen is a screen that allows the administrator to monitor the occurrence of a disaster in the tunnel 1 (whether or not a disaster has occurred and where it has occurred) and whether or not the disaster prevention equipment 2 has malfunctioned.

[0068] The upper part of the monitoring screen displays a diagram that simulates the tunnel 1 and the two warning display boards 2a and 2b on both ends of the tunnel 1, and the currently displayed characters are displayed on the two warning display boards 2a and 2b. Note that "disappeared" does not mean that the word "disappeared" is displayed on the warning display boards 2a and 2b, but rather means that no characters are displayed on the warning display boards 2a and 2b.

[0069] Additionally, multiple monitoring items are displayed in rows and columns at the bottom of the monitoring screen. Examples of monitoring items include disaster detection by each disaster prevention equipment 2 (manual report detection, fire detection, etc.) and items indicating failures of each disaster prevention equipment (TMC, TSC failure, power outage, circuit abnormality, storage battery output stop, etc.). The monitoring items may be different for each tunnel 1 (each facility location).

[0070] When an emergency occurs (for example, when a report is made by the manual reporting device 2c or an emergency telephone, when a fire is detected by the fire detection device, when a failure occurs in the disaster prevention equipment 2, or when an alarm is generated by the alarm generating unit 16), the corresponding monitoring item is highlighted on the monitoring screen. For example, if the monitoring item is a report by the manual reporting device 2c, the monitoring item corresponding to the manual report is highlighted, and if the monitoring item is a failure of the TMC 3, the monitoring item corresponding to the TMC failure is highlighted.

[0071] When a communication error occurs between the disaster prevention control device 10 and the TMC 3, the words "Transmission Error" are displayed in the upper right corner of the monitoring screen.

[0072] Additionally, a "Control Screen" operation button is displayed at the top of the monitoring screen, and when the administrator presses the "Control Screen" operation button, the screen switches to the control selection screen. Additionally, a "Main Menu" operation button is displayed at the top right of the monitoring screen, and when the administrator presses the "Main Menu" operation button, the screen switches to the facility location selection screen.

[0073] "Control screen" Next, the control screen will be described. The control screen is a screen that allows the administrator to manually control the disaster prevention equipment 2. In this embodiment, the control screen includes a control selection screen, an alarm display panel control screen, a control confirmation screen, and a circuit test control screen. The control screen may also include a control target selection screen, which will be described later.

[0074] (Control target selection screen) The control selection screen is a screen for selecting which control to execute from among various types of control that can be manually controlled by the administrator.

[0075] In this embodiment, the control selection screen allows the user to select whether to perform display control or circuit test. If display control is selected, a password is confirmed, and if the password matches, the screen switches to the alarm display control screen. On the other hand, if circuit test is selected, a password is confirmed, and if the password matches, the screen switches to the circuit test control screen.

[0076] The control selection screen can be operated to return to the monitoring screen, and can also be operated to return to the facility location selection screen (without passing through another screen).

[0077] (Alarm display board control screen) 6 is a diagram showing an example of the alarm display board control screen. The alarm display board control screen is a screen that allows the administrator to select characters to be displayed on the alarm display boards 2a and 2b.

[0078] In the upper left area of ​​the warning display board control screen, multiple selection buttons for display items on the warning display board 2 are displayed. Examples of display items include "accident occurred," "disappeared," "work in progress," and "one-way traffic." Note that, although the example shown in FIG. 6 shows a case where the number of selectable display items is four, the number of selectable display items is not particularly limited. Furthermore, the display items may be set differently for each tunnel 1 (each facility location).

[0079] The left area of ​​the alarm display board control screen displays a diagram of the two alarm display boards 2a and 2b, along with the characters currently displayed on the alarm display boards 2a and 2b. The right area of ​​the alarm display board control screen also displays the characters selected by pressing one of the selection buttons.

[0080] The "Control Start" operation button is displayed in the upper right corner of the warning display board control screen. When the administrator presses the "Control Start" operation button, the screen switches to the control confirmation screen.

[0081] The "Control Screen" operation button is displayed at the top of the warning display board control screen, and when the administrator presses the "Control Screen" operation button, the screen switches to the control selection screen. Also, the "Monitoring Screen" operation button is displayed at the top of the warning display board control screen, and when the administrator presses the "Monitoring Screen" operation button, the screen switches to the monitoring screen for the corresponding tunnel. Also, the "Main Menu" operation button is displayed at the top right of the warning display board control screen, and when the administrator presses the "Main Menu" operation button, the screen switches to the facility location selection screen.

[0082] When a communication error occurs between the disaster prevention control device 10 and the TMC 3, the words "Transmission Error" are displayed in the upper right corner of the alarm display panel control screen.

[0083] (Control confirmation screen) The control confirmation screen is a screen for confirming whether the characters selected on the alarm display board control screen should actually be displayed on the alarm display boards 2a and 2b.

[0084] If the display control is confirmed on the control confirmation screen, the characters selected on the alarm display board control screen are displayed on the two alarm display boards 2a and 2b (if disappearance is selected, nothing is displayed). On the other hand, if the display control is not confirmed, the screen returns to the alarm display board control screen.

[0085] In addition, the control confirmation screen can be operated to return to the tunnel monitoring screen, and also to the facility location selection screen (without going through another screen).

[0086] (Control target selection screen) In the explanation given here, the same characters are displayed on the two warning display boards 2a and 2b. However, it is also possible to display different characters on the two warning display boards 2a and 2b (individual display control).

[0087] In this case, a control object selection screen (not shown in the transition diagram of Figure 4) is interposed between the control selection screen and the warning display panel control screen (when entering a password, the screen transitions from the control selection screen if the password matches).

[0088] The control target selection screen is a screen for the administrator to select which of the two warning display boards 2a and 2b is to be subjected to display control.

[0089] When the administrator selects the TMC side alarm display board 2a on the control target selection screen, the screen switches to an alarm display board control screen for selecting the display content for the TMC side alarm display board 2a. On the other hand, when the administrator selects the TSC side alarm display board 2b, the screen switches to an alarm display board control screen for selecting the display content for the TSC side alarm display board 2b.

[0090] (Circuit test control screen) The circuit test control screen is a screen for the administrator to control the start and end of the circuit test of the disaster prevention equipment 2.

[0091] When the administrator selects to start the test, the circuit test begins, and when the administrator selects to end the test, the circuit test ends.

[0092] In addition, the circuit test control screen can be operated to return to the control selection screen and tunnel monitoring screen, and it is also possible to return to the facility location selection screen (without going through other screens).

[0093] "Maintenance screen" The maintenance screen is the main screen for maintaining the disaster prevention equipment 2. For example, an operation button for displaying the history related to the disaster prevention equipment 2 is displayed on the maintenance screen, and when the administrator presses this operation button, the screen switches to the history screen.

[0094] The maintenance screen can be returned to the facility location selection screen by operating the screen.

[0095] "History screen" The history screen is a screen for the administrator to check the history related to the disaster prevention equipment 2.

[0096] For example, on the history screen, it is possible to select one of multiple data sets containing a large amount of history for disaster prevention equipment (data sets containing history from a certain date, hour, minute, second to a certain date, hour, minute, second).

[0097] The history screen has a history display area in which the histories included in the selected data set are displayed, for example, in chronological order from most recent to the top. Note that the histories in this history display area may be scrollable.

[0098] The history in the history display area includes items such as "occurrence date and time," "device name," "occurrence event," and "occurrence / recovery," for example.

[0099] The "occurring event" item indicates an event that occurred in the disaster prevention equipment 2. Examples of "occurring events" include text displayed on the alarm display boards 2a and 2b, the contents of the display, reports made by the manual reporting device 2c and emergency telephones, failures of each disaster prevention equipment 2 (such as circuit abnormalities in the manual reporting device 2c), power outages, stoppage of battery output, and circuit testing.

[0100] The "Date and time of occurrence" field indicates the date and time when the event occurred. The "Device name" field indicates the identification number of the disaster prevention equipment 2 that was the target of the event (for example, if text was displayed on the alarm display boards 2a and 2b, the identification number of the target alarm display boards 2a and 2b).

[0101] Furthermore, the "Occurrence / Recovery" item indicates whether the occurrence of the event has occurred or has been recovered from. For example, if the occurrence of the event is a circuit abnormality in the manual reporting device 2c, it indicates whether the circuit abnormality has occurred or has been recovered from. For example, if the occurrence of the event is a circuit test, the "Occurrence / Recovery" item indicates whether the circuit test has started or ended. For example, if the occurrence of the event is a text display on the alarm display boards 2a, 2b, the "Occurrence / Recovery" item indicates an identification number indicating which device the administrator input a control command to (whether the input was from the disaster prevention control device 10 or from which terminal device 20).

[0102] The history may be downloadable, for example, for each currently selected data set.

[0103] The history screen can be operated to return to the maintenance screen, and can also be operated to return to the facility location selection screen (without passing through another screen).

[0104] <Effect, etc.> Next, the operation of the present technology will be described. First, as a comparative example, a case will be described in which the disaster prevention control device 10 does not have a web server function. In this comparative example, when an emergency occurs and an alarm is issued by the alarm generation unit 16, the manager must go to the front of the disaster prevention control device 10 to check the disaster occurrence status in the tunnel 1 and control the disaster prevention equipment 2, and must visually check the image displayed on the display unit 12 of the disaster prevention equipment 2 and perform any control using the operation unit 13 of the disaster prevention equipment 2. Furthermore, if an emergency occurs outside of working hours, such as at night, the manager must return to the road management office 3 and work in front of the disaster prevention control device 10 as necessary.

[0105] Furthermore, if an administrator receives an inquiry about the operation or history of the disaster prevention control device 10 while working on the terminal device 20 at his or her desk in the management office, he or she will need to move from his or her desk to the front of the disaster prevention control device 10 and visually check the image displayed on the display unit 12 of the disaster prevention equipment 2 in order to check the history, etc.

[0106] In either case, the administrator is burdened with time, effort, etc. due to the travel.

[0107] On the other hand, in this embodiment, the disaster prevention control device 10 has a web server function, so even if the manager is far from the management office (tunnel 1) such as his home, as long as he has the terminal device 20, he can monitor the occurrence of a disaster, control the disaster prevention equipment 2, and check the history of the disaster prevention equipment 2 from anywhere. Therefore, it is possible to prevent the manager from having to spend time and effort traveling.

[0108] This technology can also be implemented inexpensively by simply adding a web server function to the current disaster prevention control device 10. Furthermore, even in tunnels 1 where disaster prevention equipment 2 is connected by analog lines and no network connection is possible to the disaster prevention equipment 2, it is possible to provide information in the same way as with IP-connected devices.

[0109] [Priority] Next, priority will be explained. It is conceivable that the control of the disaster prevention equipment 2 by an administrator through input to the disaster prevention control device 10 and the control of disaster prevention of the disaster prevention equipment 2 via a web image by an administrator through input to the terminal device 20 may conflict. For example, when a disaster occurs, when an administrator causes predetermined characters to be displayed on the warning display boards 2a and 2b through input to the disaster prevention control device 10, it is conceivable that at the same time or immediately thereafter (for example, within one minute), another administrator may input a different character into the terminal device 20 to control the display of the other characters.

[0110] The administrator can be located far away from the tunnel 1, such as at home, and can control the display of the warning display boards 2a and 2b from the terminal device 20 at a location far away from the tunnel 1. However, in such a case, the display control command input to the terminal device 20 by the administrator located far away from the site, such as at home, is likely to be less reliable than the display control command input to the disaster prevention control device 10 by the administrator at the site (at the road management office 3).

[0111] Therefore, the control of the disaster prevention equipment 2 by the administrator's input to the disaster prevention control device 10 may be prioritized over the control of the disaster prevention equipment 2 via a web image by the administrator's input to the terminal device 20. By controlling the disaster prevention equipment 2 with such a priority, it is possible to respond appropriately when a collision such as the one described above occurs.

[0112] In addition, when a conflict occurs between multiple terminal devices 20, it may be determined which terminal device 20 controls the disaster prevention equipment 2 based on the command input from that terminal device, depending on the pre-set priority between the terminal devices.

[0113] [others] For example, when an emergency occurs (for example, when a report is made by the manual reporting device 2c or an emergency telephone, when a fire is detected by the fire detection device, when a failure occurs in the disaster prevention equipment 2, or when an alarm is generated by the alarm generating unit 16), the disaster prevention control device 10 may send, for example, an email or the like to the terminal device 20 indicating that an emergency has occurred. This allows the administrator to know that an emergency has occurred even if he or she is located far away from the tunnel 1. [Explanation of symbols]
