[0009] Hereinafter, embodiments (first to third embodiments) of the facility control system and facility control screen display method of the present invention will be described with reference to the accompanying drawings. In the following embodiments, a tunnel for vehicles traveling on a highway is taken as an example of a facility to be managed. Also, a fire is taken as an example of a disaster. However, facilities and disasters are not limited to these.

[0010] (First embodiment) 1 is a block diagram showing the overall configuration of a facility control system S according to a first embodiment. The facility control system S includes a facility central device 1, an operation unit 14, and a tunnel facility 2.

[0011] The tunnel facility 2 includes an information board 21 , a ventilation facility 22 , a CCTV camera 23 , a sensor 24 and a water spray device 25 .

[0012] The information board 21 is a display device for providing road users with various information about roads, tunnels, weather, and the like.

[0013] The ventilation equipment 22 is equipment for discharging exhaust gases from inside the tunnel and smoke in the event of a fire to the outside.

[0014] CCTV cameras 23 are installed inside the tunnel or near the entrances and exits, and transmit the captured images to the facility central device 1.

[0015] The sensor 24 is a variety of sensors such as a fire detector, etc. For example, the fire detector (an example of a detection unit) is installed at various locations within the tunnel, and transmits fire detection information to the facility central device 1 when it detects a fire.

[0016] The water spray device 25 includes a locking device 251 and a water spraying device 252 . The locking device 251 is a device that switches between a locked state when water is not sprayed and an unlocked state when water is sprayed. The water spraying device 252 is a device that sprays water when the locking device 251 is in the unlocked state.

[0017] The facility central device 1 is a computer device that monitors the operating status and abnormal status of the tunnel facility 2 based on information from the tunnel facility 2. The facility central device 1 is realized by a plurality of computer devices such as an information exchange server and a central processing unit, but in this embodiment, for the sake of simplicity, it will be described as a single computer device.

[0018] The facility central device 1 is connected to an operation unit 14. The operation unit 14 is an input device that accepts operations by an operator, and is, for example, a keyboard, a mouse, a touch panel, or the like.

[0019] The facility central device 1 includes an HMI (Human Machine Interface) unit 11, an information processing unit 12, and a memory unit 13. The memory unit 13 is a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The memory unit 13 stores various programs and various data. For example, the memory unit 13 stores a series of disaster response procedures (disaster prevention flow) including confirmation items and operation details in the event of a fire (disaster) occurring in the tunnel facility 2 under management.

[0020] The information processing unit 12 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). ROM is a storage medium for storing various programs and data, while RAM is a storage medium for temporarily storing various programs and rewriting various data. The CPU comprehensively controls the operation of the facility central device 1. The CPU executes programs stored in the ROM, the storage unit 13, etc., using the RAM as a work area.

[0021] The information processing unit 12 includes an acquisition unit 121 and a processing unit 122 .

[0022] The acquisition unit 121 acquires various information from the storage unit 13 and the tunnel facility 2.

[0023] The processing unit 122 executes various types of arithmetic processing, and transmits and receives various types of data to and from the control console 111, for example.

[0024] The HMI unit 11 includes a control console 111. The control console 111 includes a display unit 112, a communication unit 113, and an operation assist unit 114.

[0025] Display unit 112 is a device that displays information, and is, for example, a liquid crystal display (LCD (Liquid Crystal Display)), an organic EL (Electro-Luminescence) display, or the like.

[0026] The communication unit 113 is a communication interface for communicating with an external device of the control console 111 .

[0027] The operation assist unit 114 is a means for providing operation assistance (support) to the operator of the facility central device 1, and is, for example, a display control unit or a voice control unit. The following mainly describes the case of the display control unit.

[0028] After a fire is detected in the tunnel facility 2, the operation assist unit 114 causes the display unit 112 to display a fire status screen, an operation input screen, and the entire disaster response procedure and the current procedure. This will be explained using FIG. 2.

[0029] 2 is a diagram schematically illustrating a first example of a screen in the first embodiment. This screen is displayed on the display unit 112 after a fire in Tunnel A is detected. Area R1 displays information indicating that this screen is linked to the occurrence of a fire in Tunnel A.

[0030] Area R2 displays information indicating that the locking device 251 of the water spray device 25 is in a locked state, that the operation mode is automatic, and that the information boards are not linked.

[0031] Area R3 displays information indicating that an automatic report (fire detected by a fire detector) has been made in section 4 of sections 1 to 4 in the uphill direction of Tunnel A, and that information boards 21 in various locations have signs saying "No entry - Fire" and "Fire, stop."

[0032] Area R4 displays information indicating that the information board 21 at the entrance to Tunnel A in the downward direction displays the message "No Entry - Fire."

[0033] Area R5 displays the time elapsed since the fire started.

[0034] Area R6 displays the fire location from the entrance.

[0035] Area R7 displays the word "emergency" which can be operated to transition to another screen.

[0036] Area R8 displays information indicating the entire disaster response procedure and the current procedure. The entire disaster response procedure consists of seven procedures, steps S1 to S7. The current procedure is step S2, "Unlock Determination," which is indicated by the background color of step S2.

[0037] This allows the operator to easily understand the overall disaster response procedures and the current procedure. Specifically, the operator can see at a glance, for example, how many operations remain before water spraying (step S5) and what operations will be performed after that.

[0038] Although the current procedure is displayed by the background color of the relevant step (step S2), this is not limiting. For example, the frame of the relevant step may be a different color from the others. Alternatively, the relevant step (including just the frame) may be made to blink.

[0039] 1, the operation assist unit 114 displays at least a graphic representation of the current progress of the entire disaster response procedure on the display unit 112. This will be described with reference to FIG.

[0040] 3 is a diagram schematically showing a second example of a screen in the first embodiment. Regions R1 to R7 are the same as those in FIG.

[0041] Area R9 displays figures and text that indicate the current progress in the overall disaster response procedure. Here, as an example, there are nine steps in total (from the start of a fire to spraying water), and four steps have been completed to date. The current step is "Fire detection," and the next step is "Unlock."

[0042] This allows the operator to easily see the current progress of the entire disaster response procedure at a glance by looking at the graphic portion in area R9.

[0043] The display in area R9 is not limited to this. For example, the current progress of the entire disaster response procedure may be displayed as a percentage instead of as a fraction (4 / 9).

[0044] Alternatively, the standard time required for each step to complete the operation may be accumulated, and the ratio of the accumulated time for the steps to complete the operation to the total accumulated time may be displayed in correspondence with the area of ​​the bar that changes color.

[0045] Furthermore, the graphic is not limited to multiple inverted L-shapes, but may be multiple parallelograms, multiple diamonds, two-color display in one bar, or the like.

[0046] 1, the operation assist unit 114 displays a simulation video of each operation in the disaster response procedure as a GIF (Graphics Interchange Format) animation on the display unit 112. This will be described with reference to FIG.

[0047] 4 is a diagram showing a schematic diagram of a third example screen of the first embodiment. Here, a case where the locking equipment 251 is changed from an unlocked state to a locked state is explained. (a) is the entire screen. (b), (c), and (d) are chronologically shown animation screens displayed in the small window of (a).

[0048] When the mouse cursor (black arrow) is pointed to the area to be operated (the "Water Spray Unlock" button in area R11) on the full screen in (a), a small window will display a preview of a simulation illustrating the operation method. Specifically, first, the mouse cursor is pointed to the "Water Spray Unlock" button in area R11 on the screen in (b).

[0049] This then prompts you to select a button in area R12, as shown in screen (c). When you select that button, the button display in area R11 changes from "Water spray unlock" to "Water spray lock," as shown in screen (d).

[0050] Generally, operations in the event of a tunnel fire have a large impact on many aspects, and there are concerns that inexperienced operators may hesitate when operating, resulting in delays. This simulation function allows operators to check the actions that will be taken after an operation in advance, which not only shortens the time required for operation but also helps prevent operational errors.

[0051] Note that since the text and other elements will be small if the entire screen is displayed in a small window as shown in Figure 4, it is also possible to display an enlarged screen of the part relevant to the operation in the small window instead of the entire screen. This will be explained using Figure 5.

[0052] Fig. 5 is a diagram schematically showing a fourth example screen of the first embodiment. Fig. 5(a) is the same overall screen as Fig. 4(a). Fig. 5(b), (c), and (d) are enlarged partial screens of Fig. 4(b), (c), and (d), respectively. In this way, the parts related to the operation are displayed more clearly, making it easier for the operator to understand.

[0053] 1, when an operation is performed near the boundary of an operation button on the display unit 112, the operation assist unit 114 displays a screen requesting the user to perform the operation again. Here, "near the boundary of an operation button" includes both the meaning of "near the boundary of multiple operation buttons" and the meaning of "near the boundary of a single operation button." The following describes the former as an example.

[0054] If an operation is made near the boundary between multiple operation buttons, a screen requesting the operator to repeat the operation is displayed. This prevents operations that are not performed in accordance with the operator's intention. In the event of a tunnel fire, a single incorrect operation can have a major impact on various aspects, so this ensures that operations are performed in accordance with the operator's intention.

[0055] Furthermore, the operation assist unit 114 causes the display unit 112 to display an operation input screen for input based on the judgment result by the operator, and causes the display unit 112 to display confirmation items and / or operation contents according to the input contents on the operation input screen. This will be described with reference to FIG. 6.

[0056] Fig. 6 is a diagram showing a schematic diagram of a fifth example screen of the first embodiment. Areas R1 to R7 are the same as those in Fig. 2. Area R21 displays a screen for selecting from three options for checking the fire situation: no fire, small-scale fire, or large-scale fire. When small-scale fire is selected, a guide screen pops up in area R22 instructing the user to operate the "emergency" button in area R7 to "input water spray standby" (area R32 in Fig. 7). At this time, an audio notification may also be provided.

[0057] By instructing the operator on what to check and how to operate in this way, the operator can check the operation method on the guide screen after making a decision, which helps prevent incorrect operation, especially by operators with little knowledge or experience, and reduces the time required for operation.

[0058] The following changes are possible regarding the input of human judgments: - Display options in a pull-down list and select and enter. - Voice input by the operator

[0059] The method of teaching the operation method can also be changed as follows. - As shown in Figure 5, a series of operations are displayed in a GIF animation. - Notifications are sent only if the correct operation is not performed after a certain period of time. -Display pictograms instead of popup text - Flashes confirmation points and operation points (including pop-up displays). In addition, when you hover the mouse cursor over them, a text popup will appear with instructions on how to operate them.

[0060] Next, Fig. 7 is a diagram schematically showing a sixth example screen of the first embodiment. The screen of Fig. 7 is a screen to which the user transitions when, for example, the "emergency" button in area R7 in Fig. 2 is operated.

[0061] Area R31 displays information indicating that this screen is the screen to which the user transitions when the "emergency" button in area R7 in FIG. 2 is operated.

[0062] Area R32 displays information indicating that the locking device 251 of the water spray device 25 is in a locked state, that the operation location is far away, that the operation mode is automatic, and that the information boards are not linked. Also displayed are buttons for emergency water discharge, upstream fire confirmation, downstream fire confirmation, water spray standby input, and water spray standby input cancellation.

[0063] Area R33 displays, from top to bottom, the locations of CCTV cameras, water sprays, automatic reports (reports by fire detectors), and manual reports (reports by telephones inside the tunnel) for uphill sections 1 to 4 in the tunnel. Here, it shows that "47" in section 4 was activated in the automatic report.

[0064] Area R34 displays, from top to bottom, the corresponding positions of CCTV cameras, water sprays, automatic reports, and manual reports for sections 1 to 4 on the downhill side of the tunnel.

[0065] A guide display such as a pop-up may be displayed on the screen of FIG. 7, or the screen of FIG. 7 may be used as part of a GIF animation on another screen.

[0066] In this way, according to the facility control system S of the first embodiment, the display unit 112 can display a disaster situation screen, an operation input screen, and the entire disaster response procedure and the current procedure, thereby supporting the operator who is carrying out emergency response when a disaster occurs at the facility.

[0067] For example, in situations where emergency operations and decisions must be made during a tunnel fire, guidance on operations to be performed and areas to check during a fire can compensate for the operator's lack of experience and knowledge, reduce operating errors, and enable a faster response.

[0068] Generally, if there are errors in such judgments, confirmations, or operations, there is a risk that various types of damage may be aggravated, but in recent years, with the aging of system operators and an increase in inexperienced operators, this technology is extremely useful in such situations.

[0069] For example, when a tunnel fire occurs, confirmation and operation must be performed in accordance with the disaster prevention flow (disaster response procedures). Furthermore, when it comes to water spraying, multiple decisions must be made, such as whether or not water spraying is necessary and which areas to spray water on. This technology makes it possible to make accurate decisions and perform operations more quickly when a tunnel fire occurs, without relying on the knowledge or experience of the operator.

[0070] (Second embodiment) Next, a second embodiment will be described. Explanations of matters similar to those in the first embodiment will be omitted where appropriate. The outline of the second embodiment is as follows. Eye tracking of the system operator is performed, and when performing operations such as clicking or input, the operation is executed only when the direction of the line of sight and the operation location match. A specific description will be given below.

[0071] Fig. 8 is a block diagram showing the overall configuration of a facility control system S according to the second embodiment. In Fig. 8, a processing unit 122a includes an analysis unit 123 and a determination unit 124. An infrared camera 15 is also connected to the facility central device 1.

[0072] The infrared camera 15 is an example of a measurement unit that measures the eye movement of the operator, and captures an image of the operator using infrared rays and transmits the captured image to the facility central device 1.

[0073] The analysis unit 123 analyzes the gaze position (direction of gaze) that is the position at which the operator is looking on the display unit 112, based on the image captured by the infrared camera 15 (measurement results of the operator's eyeball movement).

[0074] When an operation is performed by the operator using the display unit 112, the determination unit 124 validates the operation only when the display position of the operation content of the operation on the display unit 112 matches the eye gaze position.

[0075] In this way, according to the second embodiment, by determining whether the operator's line of sight and the operation location coincide with each other, it is possible to contribute to preventing erroneous operations that occur due to "familiarity" in particular.

[0076] (Third embodiment) Next, a third embodiment will be described, and the description of the same matters as in the first embodiment will be omitted as appropriate. 9 is a block diagram showing the overall configuration of a facility control system S according to the third embodiment. The third embodiment is outlined as follows.

[0077] Based on the images from CCTV cameras 23 installed inside the tunnel and information obtained from sensors 24 (such as carbon dioxide concentration and visibility inside the tunnel), the system uses AI (Artificial Intelligence) to recognize the status of a tunnel fire. Then, it instructs the operator on the locations to check and the operation methods accordingly. The teaching method can be the same as that of the first embodiment. A specific explanation will be given below.

[0078] In FIG. 9, the processing unit 122 b includes a recognition unit 125 . The recognition unit 125 recognizes a fire situation in a tunnel based on the video and / or sensor information of the tunnel and a learning model for fire recognition created in advance.

[0079] Furthermore, the operation assist unit 114 causes the display unit 112 to display confirmation items and operation contents according to the fire situation.

[0080] Figure 10 is a diagram showing a typical example of a screen in the third embodiment. In Figure 10(a), areas R1 to R7 are the same as those in Figure 2. Area R41 displays the result of AI-based fire recognition (here, "small-scale fire").

[0081] Also, in Fig. 10(b), a screen for correction by the operator is displayed in area R42. That is, if the operator looks at the fire recognition result ("small fire") by the AI ​​shown in area R41 of Fig. 10(a) and determines that a change is necessary, the operator can select "no fire" or "large fire" other than "small fire" in the pull-down menu of area R42 of Fig. 10(b).

[0082] With conventional technology, the need for water spraying was determined solely by human judgment based on CCTV footage.

[0083] On the other hand, according to the third embodiment, the AI ​​makes a comprehensive judgment based not only on the video but also on, for example, the carbon dioxide concentration in the tunnel, visibility conditions, etc., and it is expected that the AI ​​will be able to make a quicker and more accurate judgment than a human would, which will contribute to preventing the spread of damage caused by incorrect judgments by the operator.

[0084] The program executed by the facility central device 1 of this embodiment is provided in a state that it is pre-installed in a ROM or the like. The program may also be provided by being recorded in an installable or executable file format on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disk (DVD).

[0085] Furthermore, the program may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network.The program may also be provided or distributed via a network such as the Internet.

[0086] The program has a modular configuration including the operation assist unit 114 of the facility central device 1. That is, the CPU reads out the program from the ROM and executes it, thereby loading the operation assist unit 114 and the like onto the main storage device.

[0087] Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This novel embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. This embodiment is included within the scope and spirit of the invention, and is also included in the invention described in the claims and their equivalents.

[0088] For example, the facilities to be managed are not limited to tunnels, and the present invention can be widely applied to all facilities to be managed. [Explanation of symbols]
