Description

[Technical Field]

[0001] An embodiment of the present invention relates to a training scenario creation device for a facility control system and a training scenario creation method for a facility control system. [Background technology]

[0002] Road control systems include traffic control systems that ensure the smooth running of vehicles, and facility control systems that monitor the status of road facilities and control their operation. Of these, facility control systems are systems that monitor the status and control the operation of various facilities and equipment installed on general roads and expressways, such as traffic information boards, traffic volume measurement equipment, weather observation equipment, equipment inside tunnels (ventilation equipment, lighting equipment, power supply equipment, etc.), and various facilities (equipment) such as traffic information boards, lighting equipment, and power supply equipment at interchanges and service areas.

[0003] In the facility control system, when a facility controller operating a control console at the road control center discovers an abnormality in road equipment, he or she will carry out the necessary operations such as driving control. Also, if the facility controller determines that on-site inspection or repair is necessary, he or she will request the dispatch of on-site workers to carry out the inspection or maintenance work, and will respond by operating the control console at the road control center, etc. as necessary.

[0004] In a facility control system, facility controllers are required to make quick and appropriate decisions and give instructions to on-site workers when an abnormality occurs in road equipment (including operational abnormalities due to power outages, fires, etc.). For this reason, facility controllers undergo training to enable them to respond quickly and appropriately when an abnormality occurs. In this case, facility controllers improve their skills by, for example, simulating response procedures and instruction procedures according to training scenarios that assume the occurrence of an abnormality. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-059181 [Patent Document 2] Japanese Patent Application Laid-Open No. 2010-020106 [Patent Document 3] Japanese Patent Publication No. 2022-186308 [Patent Document 4] Patent Publication No. 2021-004908 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the types of abnormalities that can occur in road equipment are diverse and complex. Furthermore, the methods for responding to abnormalities often differ depending on the location and cause of the abnormality (including deterioration, damage, power outages, fires, etc.). Therefore, training scenarios must be defined to be able to respond to various events that may occur during training, which requires time and effort to create. Furthermore, creating appropriate training scenarios requires detailed knowledge of the on-site equipment (road equipment).

[0007] For example, when a certain event occurs, it is necessary to predict subsequent events that may occur in relation to that event and incorporate them into the training scenario. This requires the work of experienced creators (such as veteran facility control personnel), but it is not easy to secure personnel to create training scenarios while also performing daily tasks. In addition, due to factors such as the aging of veteran facility control personnel, it has been difficult to easily create appropriate training scenarios.

[0008] Therefore, training scenarios that allow for training to ensure appropriate responses in the event of facility abnormalities are implemented. If it were possible to easily create such scenarios, it would be possible to reduce the cost of creating training scenarios, and it would also be beneficial in reducing the effort required to conduct training to respond to equipment abnormalities and the time required to start training. [Means for solving the problem]

[0009] A training scenario creation device for a facility control system according to an embodiment includes an information acquisition unit, a past event playback unit, and a training scenario creation unit. The information acquisition unit acquires message information, which is detailed events constituting past events that occurred in the past at road facilities. The past event playback unit plays back and displays the occurrence status of the past events in chronological order. The training scenario creation unit allows a user to select whether to adopt or reject the message information while referring to the played back past events, and creates a training scenario for a training event composed of the selected message information.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configurations of the embodiments described below, as well as the actions and results (effects) brought about by the configurations, are merely examples and are not limited to the following description.

[0012] The training scenario creation device of the facility control system of this embodiment plays back past events (equipment abnormalities, etc.) that actually occurred in the past in chronological order and provides them to the scenario creator, allowing them to appropriately select message information, which is the detailed events that make up the past events, and create a new training scenario that is more suitable for training.

[0013] FIG. 1 is an exemplary schematic block diagram showing the configuration of a facility control system 100 including a training scenario creation device according to an embodiment.

[0014] The facility control system 100 is installed in a road traffic control center or the like. The facility control system 100 includes a facility control central processing unit 10 that functions during normal operation, and a facility control training central processing unit 12 that functions during training.

[0015] The facility control central processing unit 10 performs functions such as managing and controlling the status of multiple road facility RMs installed at various locations, and communicating functions for sending and receiving information to and from field workers who actually manage and maintain the road facility RMs. The facility control training central processing unit 12 includes a training scenario creation device of this embodiment (a scenario creation processing unit 30, described later).

[0016] The facility control central processing unit 10 and the facility control training central processing unit 12 have the same basic functions. However, the facility control training central processing unit 12 differs from the facility control central processing unit 10 in that it is configured as a stand-alone processing unit that is not connected to the actual road facility RM (on-site equipment M), and in that it has a training scenario creation function and a training function that uses the created training scenario. In other words, the facility control training central processing unit 12 functions as an independently existing simulation unit (device).

[0017] Road facilities RM are facilities installed to ensure smooth road use and traffic flow, and include various types of equipment (local equipment M). Examples of road facilities RM include tunnel equipment RM1 installed inside tunnels, outside-tunnel road equipment RM2 installed outside tunnels, rest and service area equipment RM3, toll collection equipment RM4, radio rebroadcasting equipment RM5, CCTV equipment RM6, and transportation equipment RM7.

[0018] The road facilities RM described above are grouped and connected to the facility control central processing unit 10 via relay processing devices. The relay processing devices include, for example, a remote monitoring control device 18, a radio rebroadcasting central device 20, a CCTV central device 22, and a road traffic control central device 24.

[0019] The remote monitoring control device 18 is connected to, for example, a tunnel facility RM1, an outside-tunnel road facility RM2, a rest service area facility RM3, a toll collection facility RM4, and the like.

[0020] The tunnel facility RM1 is a facility for maintaining the tunnel so that it can be used safely and appropriately, and is equipped with multiple on-site devices M such as lighting equipment, power supply equipment, and ventilation equipment. The on-site devices M, such as lighting equipment, power supply equipment, and ventilation equipment, are equipped with measuring instruments S that measure (detect) status information (information such as whether the equipment is operating appropriately or is stopped appropriately) of each piece of equipment (on-site device M). Each measuring instrument S is, for example, a status information sensor that constantly detects the status of the on-site device M, and the detection results are provided to the facility control central processing unit 10 via the remote monitoring and control device 18.

[0021] The road facilities outside the tunnel RM2 are road facilities RM other than tunnels, and are facilities for maintaining the road so that it can be used safely and appropriately outside the tunnel. The road facilities outside the tunnel RM2 include, for example, on-site equipment M (not shown in FIG. 1) such as lighting equipment and power supply equipment. Each facility (on-site equipment M) is provided with a measuring instrument S, just like each on-site equipment M of the tunnel facility RM1, and the measurement results are provided to the facility control central processing unit 10 via the remote monitoring control device 18.

[0022] The rest and service area facilities RM3 are facilities for maintaining the safe and appropriate use of service areas (SA), parking areas (PASS), etc. The rest and service area facilities RM3 include, for example, lighting facilities, power supply facilities, and utilization status detection facilities (not shown in FIG. 1). Each facility (local equipment M) is provided with a measuring instrument S, and the measurement results are provided to the facility control central processing unit 10 via the remote monitoring and control device 18.

[0023] The toll collection equipment RM4 is, for example, equipment related to ETC (Electronic Toll Collection System), and includes a server device in the toll booth office and a roadside device (ETC gate) (not shown). Each piece of equipment (local equipment M) is equipped with a measuring instrument S, and the measurement results are transmitted to a remote monitoring station. The information is provided to the facility control central processing unit 10 via the visual control device 18.

[0024] During normal times, the radio rebroadcasting equipment RM5 retransmits radio broadcasts sent from the facility control central processing unit 10 inside tunnels where radio waves cannot reach. In addition, the radio rebroadcasting equipment RM5 operates as a disaster prevention public address system during disasters. Each piece of equipment (local equipment M) included in the radio rebroadcasting equipment RM5 is provided with a measuring instrument S (not shown) that measures (detects) the status information of each piece of equipment (local equipment M), and the measurement results are provided to the facility control central processing unit 10 via the radio rebroadcasting central device 20.

[0025] The CCTV equipment RM6 is a camera that captures images showing traffic conditions, and is installed in appropriate locations both inside and outside the tunnel. Each CCTV is equipped with a measuring instrument S (not shown) that measures (detects) status information on its operating status (such as imaging status), and provides the measurement results to the facility control central processing unit 10 via the CCTV central unit 22.

[0026] Traffic equipment RM7 includes variable traffic information boards, traffic volume measurement equipment, highway radio ( (Equipment that transmits traffic congestion information to moving vehicles by radio), weather equipment, and equipment installed at SAs and PAs. This includes information boards (displaying full / empty status, required time, etc.) installed in the facility control center 10. Each facility (local equipment M) is provided with a measuring instrument S (not shown) that measures (detects) status information of its operating status (image capture status, etc.), and the measurement results are provided to the facility control central processing unit 10 via the road control central device 24.

[0027] The measuring instruments S provided in each facility (on-site equipment M) are, for example, status information sensors that constantly detect the status of the facility and provide it to the facility control central processing unit 10 via the relay processing device described above. The facility control central processing unit 10 analyzes the status information provided from each measuring instrument S.

[0028] The above-mentioned road facility RM is just one example, and there are various facilities (equipment, local equipment M) for improving the usability of roads, which are controlled and managed by the facility control central processing unit 10.

[0029] First, the facility control central processing unit 10 will be described in detail.

[0030] The facility control central processing unit 10 includes a control function for managing and controlling the status of the on-site equipment M installed at each road facility RM based on instructions from a controller who performs control operations at a control desk at an automatic or road control center, etc.

[0031] The facility control central processing unit 10 can be configured with computer resources such as a general PC or server. The facility control central processing unit 10 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and The facility control central processing unit 10 is configured with a storage unit such as a hard disk drive (HDD) or a solid state drive (SSD). The CPU constituting the facility control central processing unit 10 reads a facility management program installed and stored in a nonvolatile storage unit such as a ROM or SSD, and realizes various modules according to the facility management program. For example, modules such as a tunnel CCTV processing unit 10a, a large display processing unit 10b, a tunnel broadcast processing unit 10c, and an external terminal processing unit 10d are realized.

[0032] The tunnel CCTV processing unit 10a constantly monitors the inside of the tunnel by processing images from cameras installed inside the tunnel.

[0033] The large display processing unit 10b displays on a large display at the road control center not only the camera images provided by the tunnel CCTV processing unit 10a but also the detection results of the sensors installed in the tunnel, circular information in the tunnel, the operating status of each local device M installed in the tunnel, etc. The large display processing unit 10b may also perform processing to display on the large display information, etc., displayed on the display unit of the control console, provided by the screen display processing unit 14a of the HMI unit 14, which will be described later.

[0034] The tunnel broadcast processing unit 10c manages and transmits information that can be received inside the tunnel (rebroadcast information). The tunnel broadcast processing unit 10c may also provide broadcast content directly to the receiving devices of vehicles inside the tunnel.

[0035] The external device processing unit 10d is installed, for example, in a service area (SA) or a parking area (PA), and has a function of transmitting and controlling various information in real time to a terminal device that can be seen and operated by users such as general drivers. The external device processing unit 10d can also transmit and operate various information in real time to road information boards and the like installed on roads, in tunnels, service areas, etc. The external device processing unit 10d may also provide information to terminal devices carried by drivers or other systems linked to the facility control system 100.

[0036] 1 shows only one example of the modules realized by the facility control central processing unit 10 for convenience of illustration, and the others are omitted. The facility control central processing unit 10 can realize processing modules corresponding to each road facility RM, communication processing modules that control communication and information transmission between field workers and facility controllers and communication between each device, and information management modules that manage acquired and generated information.

[0037] The facility control central processing unit 10 also performs a storage process for sequentially storing message information and the like indicating the operating status of the road facility RM (local equipment M) and the details of any malfunctions that have occurred (including abnormalities in road facilities).

[0038] The facility control central processing unit 10 includes, for example, an HMI (Human Machine Interface) unit 14 , a storage unit 16, etc. are connected to the ROM 11.

[0039] The screen display processing unit 14a of the HMI unit 14 controls the display unit for the facility control central processing unit 10 and the display unit for the facility control training central processing unit 12. The HMI unit 14 is an intermediary device that facilitates mutual communication between the facility control central processing unit 10 and a facility controller who performs control work at a road control center or the like. The HMI unit 14 is also connected to the facility control training central processing unit 12, and functions as an intermediary device that facilitates mutual communication between the facility control training central processing unit 12 and a scenario creator who creates a training scenario, a trainee who receives training using the created training scenario, and the facility control training central processing unit 12. The facility control central processing unit 10 and the facility control training central processing unit 12 may each be provided with their own dedicated HMI unit 14.

[0040] The HMI unit 14 includes, for example, a screen display processing unit 14a, an input unit 14b, and a teacher data input unit 14c.

[0041] The screen display processing unit 14a controls the display unit of the control console operated by the facility control staff. The display unit may be configured, for example, with an LCD (liquid crystal display) or an OLED (organic electroluminescent display). The screen display processing unit 14a may provide the display content of the control console's display unit as display information on a large display installed in the road control center, or may provide display information to other devices.

[0042] The input unit 14b is a device for facility control personnel and the like to input operation details and various information for managing and controlling the status of the on-site equipment M. The input unit 14b is an input device (keyboard, mouse, etc.) for the facility control central processing unit 10 and an input device (keyboard, mouse, etc.) for the facility control training central processing unit 12. The input unit 14b may also have a function for inputting instructions to field workers. The input unit 14b can receive input content via an input device such as a keyboard or a mouse, as well as a voice input device or a gesture input device. The input unit 14b may also be integrated with a display unit controlled by the screen display processing unit 14a. When the display unit and the input unit 14b are integrated, the display unit is covered with a transparent operation unit such as a touch panel.

[0043] The teacher data input unit 14c functions to input teacher data when the facility control training central processing unit 12 uses a machine learning function to create a base scenario that serves as a basis for a training scenario. Like the input unit 14b, the teacher data input unit 14c can receive input via input devices such as a keyboard or mouse, as well as a voice input device or a gesture input device. The teacher data input unit 14c may also be integrated with a display unit used when creating a training scenario. When the display unit and the teacher data input unit 14c are integrated, the display unit is covered with a transparent operation unit such as a touch panel. Since the display unit that displays various information during operation always displays an operation screen, it is desirable that the display unit that displays various information during training scenario creation or training be configured as an independent device.

[0044] The screen display processing unit 14a of the HMI unit 14 controls the display unit for the facility control central processing unit 10 and the display unit for the facility control training central processing unit 12. Similarly, the input unit 14b controls the input devices (keyboard, mouse, etc.) for the facility control central processing unit 10 and the input devices for the facility control training central processing unit 12. The teacher data input unit 14c may control the input device for the facility control training central processing unit 12 connected to the input unit 14b, or may control a dedicated input device for teacher data input.

[0045] The storage unit 16 is configured with an HDD, SSD, etc. The storage unit 16 sequentially stores information about past events that occurred in the road facility RM (on-site equipment M) in chronological order, such as location information, date and time information, and details of the occurrence of the past event. The various pieces of information (message information, which is detailed events that make up the past event) stored in the storage unit 16 are called up in chronological order according to specified items, and the events that occurred are played back in chronological order.

[0046] In addition, the various information stored in the storage unit 16 is used as reference data when the facility control training central processing unit 12 creates a training scenario.

[0047] The storage unit 16 also stores information processed by the facility control training central processing unit 12, such as new training scenarios and information on how they were created. The training scenarios stored in the storage unit 16 are called up during training and used to train trainees to deal with malfunctions that may occur in road facilities RM. Details of the creation of training scenarios will be described later.

[0048] As described above, the memory unit 16 provides the scenario creation processing unit 30 with information about detailed events that constitute past events that have occurred in the past at the stored road facility RM (on-site equipment M). In other words, the memory unit 16 provides creation data for a new training scenario. The memory unit 16 also stores new training scenarios created by the scenario creation processing unit 30, and when actual training is carried out, provides actual past event information and event information based on the training scenario to the scenario training processing unit 28, causing the training to be carried out.

[0049] In this way, the facility control central processing unit 10 performs integrated management of the type, number, operation status, management status, and mutual equipment cooperation status of the on-site devices M installed in each road facility RM installed on the expressway, etc., and processes various information. In addition, the facility control central processing unit 10 processes information provided from the control console (facility controller) side and information provided from each road facility RM (on-site devices M) (operation information, Based on the information received from the road facility management system (such as road accident information), the system can generate and process information to manage and control each road facility RM (local equipment M) and issue instructions to the local equipment M and field workers, etc.

[0050] Next, the facility control training central processing unit 12 will be described in detail.

[0051] As described above, the basic functions of the facility control training central processing unit 12 and the facility control central processing unit 10 are equivalent. However, the facility control training central processing unit 12 is configured as a stand-alone processing unit that is not connected to actual on-site equipment M. Furthermore, the facility control training central processing unit 12 differs from the facility control central processing unit 10 in that it has a training scenario creation function and a training function that uses the created training scenario.

[0052] The facility control training central processing unit 12 is connected to an HMI unit 14 and a memory unit 16. In other words, the HMI unit 14 and the memory unit 16 are shared with the facility control central processing unit 10. The facility control training central processing unit 12 includes a scenario training processing unit 28, a scenario creation processing unit 30, etc.

[0053] The facility control training central processing unit 12 can be configured with computer resources such as a general-purpose PC. The facility control training central processing unit 12 is configured with a CPU, ROM, RAM, and a storage unit such as an HDD or SSD. The CPU constituting the facility control training central processing unit 12 reads a training program installed and stored in a non-volatile storage unit such as a ROM or SSD, and realizes modules such as a scenario training processing unit 28 and a scenario creation processing unit 30 in accordance with the training program. Note that functions other than the training function in the facility control training central processing unit 12 are basically the same as those of the facility control central processing unit 10, and therefore a description thereof will be omitted.

[0054] The scenario training processing unit 28 performs response training for the trainee by recreating situations that resemble actual events, such as control and management operations for road facilities RM (on-site equipment M), and response operations when a malfunction occurs in on-site equipment M, in accordance with the training scenario created by the scenario creation processing unit 30. The scenario training processing unit 28 may also provide new events that may occur due to the trainee's response, and may evaluate the trainee's response and point out problems.

[0055] The scenario creation processing unit 30 is a processing unit that semi-automatically creates new training scenarios that can be reproduced by the scenario training processing unit 28 based on message information, which is detailed events that constitute past events that occurred in the past at each road facility RM (local equipment M).

[0056] The scenario creation processing unit 30 includes detailed modules such as a specified message history reading unit 30a, a message history playback unit 30b, a message history selection unit 30c, a related screen transition processing unit 30d, an on-related screen icon selection unit 30e, a training scenario creation unit 30f, a teacher data storage processing unit 30g, a base scenario generation unit 30h, and a base scenario editing unit 30i. These detailed modules may be configured as dedicated hardware.

[0057] The designated message history reading unit 30a functions as an information acquisition unit. The designated message history reading unit 30a acquires message information, which is detailed events constituting past events that occurred in the road facility RM (on-site equipment M), from the storage unit 16 as message information that can constitute a training scenario.

[0058] FIG. 2 is an exemplary explanatory diagram showing a history screen GA including a message history list GAL showing message information constituting past events that occurred in the road facility RM (on-site equipment M) in the past when a training scenario was created in the training scenario creation device (scenario creation processing unit 30) according to the embodiment. Figure.

[0059] The history screen GA displays message information, which is detailed events constituting past events that actually occurred during past operation of the road facility RM (on-site equipment M). In the specified message history reading unit 30a, for example, by specifying the date and time of occurrence of the event to be referenced via the input unit 14b, it is possible to acquire a message history list GAL (message information) starting from the specified date and time of the past event. FIG. 2 shows, as an example, the message history list GAL for an event that occurred on November 17, 2023. Furthermore, by specifying the event to be referenced (e.g., a power outage in a tunnel) in the specified message history reading unit 30a, it is possible to acquire a message history list GAL (message information) starting from the specified past event. As a result, it is possible to efficiently acquire a history of message information related to an event that occurred from a certain date and time or a history of message information from the start of a certain event.

[0060] Furthermore, the history screen GA shown in FIG. 2 displays a management office bar Ja for each management office in charge of a management area, which is an example of a history playback menu.

[0061] That is, by selecting a desired management office bar Ja (for example, by placing the cursor on it), the display contents of the message history list GAL can be narrowed down to the specified management office (management area) and displayed.

[0062] Furthermore, by selecting the desired management office bar Ja, a pull-down menu (location tab) is displayed, allowing you to select a location included in the management office (management area) (for example, Aiu IC (interchange), Eoka IC, Tachitsu TN (tunnel), etc.). In this case, the message history list GAL displays a history list of events that occurred at the specified location.

[0063] Furthermore, by placing the cursor on a desired location tab, detailed information about the desired location can be displayed as a message history list GAL. For example, information indicating the power distribution status, a list of equipment, a list of faults, etc., at the selected location can be displayed as a message history list GAL. When displaying the message history list GAL, the message history list GAL may be displayed for each level of the pull-down menu, or the message history list GAL may be displayed after a selection is made in the lowest-level pull-down menu.

[0064] The message history playback unit 30b plays back and displays the occurrence status of past events selected on the history screen GA in chronological order. For example, when a power outage event at an interchange is selected on the history screen GA, the message history playback unit 30b displays the details of the events from the time of the actual power outage that occurred at the specified interchange and the history of the response process for each event in chronological order. By playing back the occurrence status in chronological order using the message history playback unit 30b, the occurrence status of past events can be provided to the scenario creator in a manner that is intuitively easy to understand. In this case, if the specified message history reading unit 30a acquires the message history list GAL (message information) based on a date and time, the history of message information and related screens from a certain point in time (date and time) are played back as if they were at that time.

[0065] Furthermore, when the message history list GAL (message information) is acquired with a specified event as the starting point in the specified message history reading unit 30a, the history of message information from the occurrence of a certain event (failure in the facility) and related screens are played back just as they were at the time. As a result, the scenario creator can check the progress of the event that occurred on the specified date and time, or the progress of the occurrence of a certain event, as the situation progressed just as it was at the time.

[0066] The message history reproducing unit 30b can also fast-forward and rewind the occurrence status of past events, making it easier to check the occurrence status of past events, event transitions, and response transitions.

[0067] The message history selection unit 30c allows the scenario creator to select whether to include message information included in past events that the scenario creator wants to include in the training scenario to be created while referring to the past events played back by the message history playback unit 30b. By selecting whether to include message information of past events in the training scenario using the message history selection unit 30c, the content of the newly created training scenario can be customized to suit the desired training.

[0068] In addition, by referring to responses to past events, it is possible to create ideal scenarios for achieving more efficient or optimal responses, and to create training scenarios that can contribute to optimal response training in the event of a malfunction in road facility RM (local equipment M).

[0069] The related screen transition processing unit 30d transitionally displays related information displayed on the same screen in accordance with changes in the history information played back by the message history playback unit 30b. By displaying related information in a transitional manner by the related screen transition processing unit 30d, related information to be considered when the message history selection unit 30c selects whether to include message information of past events in a training scenario is displayed, which contributes to enabling easier and more accurate selection of whether to include message information.

[0070] For example, a malfunction that was not included in a chain reaction of malfunctions in past events may be included in an event that occurs in the future. Malfunctions of on-site device M that were not included in actual past events must be included in training scenarios that are carried out based on the training scenario. In other words, by providing related information using the related screen transition processing unit 30d, even creators who have little experience or insufficient knowledge in creating training scenarios can easily obtain various information.

[0071] As a result, the scenario creation processing unit 30 of this embodiment can easily increase the variety of training scenarios and contribute to improving the quality of training scenarios.

[0072] The related screen icon selection unit 30e makes it possible to incorporate into the training scenario being created icons that are displayed on the playback screen when playing back past events, making it easier to visually recognize occurrence information and related information of past events. Adding related icons to the training scenario using the related screen icon selection unit 30e can contribute to the enrichment and improvement of the training scenario. In this way, by incorporating related icons into the training scenario, it is possible to, for example, clarify the items on the screen that should be checked during training, thereby contributing to the improvement of training quality.

[0073] The training scenario creation unit 30f creates a training scenario for a training event that can be used in training, based on the information selected in the message history selection unit 30c and the related screen icon selection unit 30e. The training scenario creation unit 30f may be configured to allow the content of a training scenario that has been created to be reconfirmed, and further to allow message information to be added or deleted, thereby improving the accuracy of the training scenario and increasing its variety.

[0074] The training scenario creation unit 30f formats the training scenario as a new training scenario that can be reproduced by the scenario training processing unit 28. Then, the scenario creation processing unit 30 stores the completed training scenario in the memory unit 16. Note that the message history selection unit 30c and the related on-screen icon selection unit 30e may be included in the training scenario creation unit 30f.

[0075] Figures 3 to 5 show examples of screens that are displayed on the display unit during the creation process of a training scenario. Figures 3 to 5 show, as an example, a scenario addition screen GB that includes the transition of the power distribution screen showing the power distribution situation when a power outage occurs at "Aiu IC."

[0076] FIG. 3 is an exemplary schematic explanatory diagram showing a scenario addition screen including a transition screen displayed in the first half when creating a training scenario in the training scenario creation device (scenario creation processing unit 30).

[0077] The scenario addition screen GB displays an enlarged main screen Gm1, which is a power distribution screen for "Aiu IC" selected via the input unit 14b, in the approximate center. The main screen Gm1 in FIG. 3 displays a power outage on the power purchase line La through which electricity purchased from the power company (purchased power) is introduced. The situation that occurred is shown.

[0078] When a power outage occurs, circuit breakers Cb1, Cb2, and Cb3 on the power purchase line La remain closed (shown solid in the illustration). Circuit breaker Cb4 is open (shown white in the illustration). Also, because switch Cs1 is flipped to the power purchase line La side, power is not supplied to the local equipment M (TN ventilation, TN lighting AC, street equipment) downstream of switch Cs1, resulting in a power outage. Also, circuit breaker Cb5 on the private power generation line Lb side is open. In other words, no power is being supplied to any of the local equipment M.

[0079] Therefore, when a power outage occurs, a state in which no power is being supplied to any of the local devices M is displayed. By selecting an icon using the related screen icon selection unit 30e while referring to the main screen Gm1, the display content of the main screen Gm1 displayed in the training scenario can be customized to content suitable for training.

[0080] A plurality of reduced-size sub-screens Gm2 to Gm9 are displayed in the left and right regions of the main screen Gm1.

[0081] For example, the sub-screens Gm2 to Gm5 display detailed information about the devices included in the main screen Gm1 (such as power distribution location information, operation mode information, and inverter status information) in reduced windows. Also, the sub-screens Gm6 to Gm9 display information other than the power distribution screen on the main screen Gm1 as inactive information. Inactive information is, for example, information about lighting devices and ventilation devices, and is displayed in a semi-transparent state, for example.

[0082] Sub-screens Gm2 to Gm5 that show detailed information on the main screen Gm1 can be enlarged by selecting them, improving visibility and allowing the information to be added to the training scenario.

[0083] In addition, inactive sub-screens Gm6 to Gm9 can be activated by selecting them and enlarged to improve visibility. In other words, inactive information can also be added to the training scenario. By selecting whether to accept or reject message information from the message history using the message history selection unit 30c, the content of the training scenario can be customized to suit the training. Note that circuit breakers Cb1 to Cb4 are displayed in a distinguishable manner by different display colors or different display modes such as on, off, or flashing to indicate whether their current state is open or closed.

[0084] The scenario addition screen GB also includes a message history list GBL and an addition target list Gma.

[0085] The message history list GBL is displayed, for example, at the bottom of the main screen Gm1, and displays, as text information, message history (plurality of message information) which is detailed events that make up past events corresponding to the display status of the main screen Gm1. The message history selection unit 30c can select message information that the user wishes to incorporate into the training scenario to be created from the message history displayed in the message history list GBL.

[0086] The addition target list Gma can display a list of items to be added to the training scenario by copying and pasting from the message history corresponding to the display status of the main screen Gm1 displayed in the message history list GBL.

[0087] The message history selection unit 30c is an area that displays a list of message information that the user wishes to incorporate into the training scenario being created from the message history displayed in the message history list GBL. By displaying the message information to be incorporated into the training scenario in the addition target list Gma, it is possible to easily check the configuration of the training scenario being created. Note that the training scenario creation unit 30f may automatically rearrange and display the message information in chronological order even if the message information is copied and pasted into the addition target list Gma without considering the chronological order.

[0088] The message information to be incorporated into the training scenario may be automatically added to the addition target list Gma by checking the message information displayed in the message history list GBL.

[0089] A seek bar 32 is located, for example, at the bottom of the scenario addition screen GB. When the message history playback unit 30b plays back and displays the occurrence status of past events in chronological order, the seek bar 32 enables fast-forwarding or rewinding of the playback scene regardless of the playback state set by operating the play button 32a or stop button 32b. As a result, it is possible to easily check the playback content of past events.

[0090] FIG. 4 is an exemplary schematic explanatory diagram showing a scenario addition screen including a transition screen that is displayed midway through training scenario creation in the training scenario creation device.

[0091] 4 shows a state in which the circuit breaker Cb1 on the power purchase line La is open, as a transition in the situation after the occurrence of a power outage. In other words, by playing back the history in chronological order using the message history playback unit 30b, it is possible to visually indicate that, as a response to a power outage in the training scenario, it is necessary to add a check on the situation after the occurrence of a power outage to determine whether the circuit breaker Cb1 on the power purchase line La is open.

[0092] FIG. 5 is an exemplary schematic explanatory diagram showing a scenario addition screen including a transition screen that is displayed in the latter half of training scenario creation in the training scenario creation device.

[0093] The main screen Gm1 in Figure 5 shows the transition of the situation after the power outage, in which the circuit breaker Cb1 on the power purchase line La opens, and then the circuit breaker Cb5 on the private power generation line Lb side closes. Also, the screen shows the transition of the switch Cs1 to the side of the private power generation line Lb.

[0094] As a result, it is shown that the power outage of the on-site device M shown in Figures 3 and 4 has progressed to a state where it has been partially resolved as a first stage. In other words, by playing back the history in chronological order using the message history playback unit 30b, it is possible to visually indicate which on-site device M should be added as the on-site device M whose recovery should be confirmed first after the occurrence of a power outage in the training scenario.

[0095] As described above, the message history playback unit 30b of the scenario creation processing unit 30 displays the main screen Gm1, which is a screen transition diagram showing the occurrence status of past events, and also displays a message history list GAL listing message information and an addition target list Gma showing items to be added to the training scenario, arranged on the same screen as the scenario addition screen GB.

[0096] As a result, various message information that can be added to a newly created training scenario can be provided in a state that is easy to consider, and it becomes easier to visualize the overall picture of the newly created training scenario, which contributes to the efficient creation of training scenarios.

[0097] For example, when creating a training scenario based on past events, a malfunction that did not occur in the past events may occur due to a slight change in conditions at the time the malfunction occurred. In such cases, the message information provided on the sub-screens Gm2 to Gm9 displayed on the scenario addition screen GB can be easily referenced.

[0098] As a result, even if there is variation in knowledge regarding the on-site equipment M among scenario creators, it is possible to provide the necessary information as appropriate, thereby reducing the variation in the quality of the created training scenarios.

[0099] Furthermore, the specified message history reading unit 30a can acquire message information starting from a specified date and time of a past event, and the message history reproducing unit 30b can reproduce the past event starting from the specified date and time. As a result, past events can be searched for by a specified date and time, and a new training scenario can be created based on the past events narrowed down by the specified date and time. This contributes to the efficient creation of a new training scenario corresponding to the desired training.

[0100] Furthermore, the specified message history reading unit 30a can acquire message information that starts from a past event of the specified event, and the message history reproducing unit 30b can reproduce past events that start from the specified event. As a result, past events can be searched for by the specified event, and a new training scenario can be created based on the past events narrowed down by the specified event. This contributes to the efficient creation of a new training scenario that corresponds to the desired training.

[0101] Furthermore, the designated message history reading unit 30a acquires message information originating from a designated occurrence location of a past event, and the message history reproducing unit 30b reproduces the past event originating from the designated occurrence location. As a result, past events can be searched for at the designated occurrence location, and a new training scenario can be created based on the past events narrowed down by the designated occurrence location. This contributes to the efficient creation of a new training scenario corresponding to the desired training.

[0102] In this way, the training scenario creation device (scenario creation processing unit 30) of this embodiment plays back past events and selects events to be incorporated into the training scenario. As a result, the created training scenario makes it possible to easily predict events that follow, for example, the occurrence of a malfunction in a certain event (on-site device M), and incorporate those events into the training scenario.

[0103] Furthermore, when creating a training scenario, the training scenario creation device (scenario creation processing unit 30) can easily add events related to possible malfunctions that were not included in past events. As a result, it is possible to easily create a training scenario that allows training to be conducted so that appropriate responses can be made to events that have not been handled in the past when a facility abnormality occurs. Furthermore, by creating a training scenario in this way, it is possible to reduce the cost of creating a training scenario, reduce the effort required to conduct training to respond to equipment abnormalities, and shorten the time until the training begins. This will help shorten travel times, etc.

[0104] 1, the training data storage processing unit 30g, base scenario generating unit 30h, and base scenario editing unit 30i included in the scenario creation processing unit 30 function to create a reference base scenario using techniques such as machine learning, using past events that occurred in the past as training data. By using a base scenario created in advance, it is possible to easily create a new training scenario that assumes, for example, the occurrence of a similar event (such as a malfunction of on-site device M) in the base scenario at a location different from the location where the event occurred.

[0105] The teacher data storage processing unit 30g sequentially stores message information, which is detailed events that constitute past events that occurred in the past, in the storage unit 16 as teacher data that can be used in well-known techniques such as machine learning, regardless of whether the information is classified by the date and time of occurrence, the location of occurrence, the content of the event, etc., and builds it into a database. Note that a storage unit for machine learning may be provided separately from the storage unit 16.

[0106] The base scenario generation unit 30h uses the training data stored in the memory unit 16 to generate a hypothetical scenario as a base scenario that differs from the content of an event that actually occurred. In other words, it creates a fictitious scenario as a base scenario that reproduces a malfunction of road facilities RM (local equipment M) that has not occurred in the past. By using a fictitious base scenario, it is possible to easily create scenarios that would not normally occur, such as scenarios that are more difficult to deal with or that easily address the trainee's weaknesses. Therefore, the training data storage processing unit 30g functions as a learning unit together with the base scenario generation unit 30h.

[0107] The base scenario editing unit 30i has a function of editing a base scenario automatically created by machine learning into a training scenario intended by the scenario creator that is more suitable for training. As mentioned above, a base scenario does not necessarily match actual past events that occurred in the past.

[0108] Therefore, the scenario creator can add unnecessary events to the training scenario, or conversely, events that are not included in the base scenario but are desirable to incorporate into the training. In this way, the base scenario editing unit 30i can selectively delete teacher message information from the base scenario and selectively add new message information for events that may occur in different locations. For example, by deleting multiple message information included in the base scenario or adding message information not included in the base scenario, it is possible to adjust the difficulty of responding and the trainee's weaknesses, and create a training scenario that is more suitable for training.

[0109] The base scenario from which message information has been deleted or added in the base scenario editing unit 30i is provided to the scenario creation processing unit 30, where it is formatted as a new training scenario that can be reproduced by the scenario training processing unit 28. The scenario creation processing unit 30 then stores the completed training scenario in the memory unit 16.

[0110] The processing flow in the scenario creation processing unit 30 configured as above will be described with reference to the flowcharts of FIGS.

[0111] FIG. 6 is an exemplary flowchart showing the procedure for creating a training scenario based on a past event in the training scenario creation device (scenario creation processing unit 30).

[0112] In step S100, the scenario creation processing unit 30 checks whether or not the training scenario creation mode has been activated by the scenario creator via the input unit 14b.

[0113] In step S100, if the answer is "No," that is, if the training scenario creation mode is started, In this case, no operation has been performed, and this flow is temporarily terminated.

[0114] If the answer is "Yes" in step S100, that is, if an operation to start the training scenario creation mode has been performed, the process proceeds to step S102, and the scenario creation processing unit 30 displays, for example, a history screen GA as shown in Fig. 2 on a display unit connected to the facility control training central processing unit 12. As described above, the history screen GA displays the management office bar Ja, which is an example of a history playback menu.

[0115] In step S102, the scenario creation processing unit 30 allows the user to select search conditions (management area, location, on-site equipment M, etc.) for creating a training scenario from the management office bar Ja displayed on the history screen GA. Then, the process proceeds to step S104.

[0116] In step S104, the scenario creation processing unit 30 causes the display unit to display a scenario addition screen GB such as that shown in Figures 3 to 6. That is, message information is displayed in chronological order based on past events. Thereafter, the process proceeds to step S106.

[0117] In step S106, the message history selection unit 30c and the related screen icon selection unit 30e allow the scenario creator to select message information and icons to be added to or deleted from the training scenario being created. This selection can be made by editing the addition target list Gma by checking or unchecking message information on the message history list GBL.

[0118] As another selection method, the addition target list Gma may be edited by a drag operation. By editing this addition target list Gma, the training scenario can be made into a desired scenario.

[0119] Then, in step S108, the training scenario creation unit 30f confirms that the scenario creation work is complete by checking whether the "scenario creation complete" button has been operated.

[0120] If the answer is "No" in step S108, that is, if the training scenario is still being created (edited), the process proceeds to step S106, and the process of selecting whether to add or delete message information is repeated.

[0121] In step S108, if the answer is "Yes," that is, if the creation (editing) of the training scenario is complete, the training scenario creation unit 30f formats it as a new training scenario that can be reproduced by the scenario training processing unit 28, stores it in the memory unit 16, and temporarily terminates this flow.

[0122] The created training scenario is completed as follows, for example, according to past events: occurrence of event A → occurrence of event B → occurrence of event C → occurrence of event X1, which did not occur in the past events → occurrence of event X2 → response to event X2 → response to event X1 → response to event C → response to event B → response to event A, etc. As a result, it becomes possible to carry out training to resolve malfunctions caused by the occurrence of hypothetical event A, without regard to the training.

[0123] Furthermore, in other training scenarios, it is easily possible to add a B1 event instead of a B event, and create training scenarios that develop into other scenarios.

[0124] In this way, the scenario creation processing unit 30 of this embodiment plays back and displays message information constituting past events in chronological order. Then, while referring to past events that have actually occurred, it creates a training scenario to be used in response training when a malfunction or the like occurs in road facilities RM (on-site equipment M). As a result, it is possible to easily and efficiently adjust the difficulty level of a newly created training scenario and create a training scenario that is suited to the trainee's level of proficiency.

[0125] In addition, creating training scenarios in this manner can contribute to reducing the cost of creating training scenarios, reducing the effort required to conduct training to respond to equipment abnormalities, and shortening the time required to start training.

[0126] Next, as another form of creating a training scenario, an example of creating a base scenario as a reference using machine learning technology, and a procedure for creating a virtual training scenario using this base scenario will be described.

[0127] FIG. 7 is an exemplary flowchart showing the procedure for creating a base scenario by machine learning in the training scenario creation device (scenario creation processing unit 30).

[0128] In step S200, the scenario creation processing unit 30 checks whether the learning mode of the facility control training central processing unit 12 has been activated by the scenario creator via the input unit 14b (whether learning has started).

[0129] If the answer is "No" in step S200, that is, if the learning mode has not been activated, the flow ends.

[0130] If the answer is "Yes" in step S200, that is, if the learning mode has been activated, the process proceeds to step S202, where the teacher data storage processing unit 30g checks whether it has acquired a history of message information that constitutes past events that occurred in actual operation.

[0131] If the answer is "No" in step S202, that is, if message information constituting past events that occurred in actual operation has not been acquired, and it can be assumed that there is no learning target, the process returns to step S200 and waits for an instruction to start the learning mode, that is, for the timing at which message information indicating past events to be learned can be acquired.

[0132] If the answer is "Yes" in step S202, that is, if the learning mode has been activated, the process proceeds to step S204.

[0133] In step S204, the teacher data storage processing unit 30g extracts, for example, message information that occurs intermittently at the same location from the acquired message information. That is, it collects occurrence patterns of malfunctions of local equipment M that may occur at a certain road facility RM, and then proceeds to the processing of step S206.

[0134] In step S206, the base scenario generating unit 30h arranges the extracted message information in chronological order in the order in which the events occurred, and learns it as information that constitutes the base scenario, and then proceeds to step S208.

[0135] Then, in step S208, the base scenario generating unit 30h checks whether the base scenario generating work has been completed.

[0136] If the answer is "No" in step S208, that is, if the extraction and chronological arrangement of message information occurring intermittently at the same location has not yet been completed, the process proceeds to step S204, and the message information extraction process continues.

[0137] If the answer is "Yes" in step S208, that is, if the creation (editing) of the base scenario is complete, the process proceeds to step S210.

[0138] In step S210, the base scenario generating unit 30h prepares a base scenario in a format that can be reproduced by the scenario training processing unit 28, stores the base scenario obtained as a result of learning in the storage unit 16, and then ends this flow for the time being.

[0139] In this way, for example, a base scenario is created by collecting message information that constitutes past events that occurred at the same location using machine learning technology. As a result, a standard scenario (base scenario) can be created that can be used for training on how to respond to malfunctions in road facilities RM (on-site equipment M) that have not actually occurred in the past but may occur. As a result, when creating a new training scenario, it becomes easier to create a training scenario for how to respond to malfunctions in virtual new road facilities RM (on-site equipment M).

[0140] Next, a procedure for creating a virtual training scenario will be described, in which a new virtual training scenario is created using the created base scenario.

[0141] FIG. 8 is an exemplary flowchart illustrating a procedure for creating a training scenario using a base scenario in the training scenario creation device according to the embodiment.

[0142] In step S300, the scenario creation processing unit 30 checks whether or not the training scenario creation mode of the facility control training central processing unit 12 has been activated by the scenario creator via the input unit 14b.

[0143] If the answer is "No" in step S300, that is, if the training scenario creation mode has not been started, the flow is temporarily ended.

[0144] If the answer is "Yes" in step S300, that is, if the training scenario creation mode has been activated, the process proceeds to step S302.

[0145] In step S302, the user selects the base scenario menu displayed on the display unit. As mentioned above, the base scenario is constructed based on message information that occurs intermittently at the same location. Therefore, although the base scenario includes events that actually occurred, it is not a scenario that completely matches real-world events, but rather a hypothetical scenario.

[0146] For example, this would be a scenario of a hypothetical event that could occur in a typical tunnel facility. In step S302, in the base scenario menu, the "location" and "event" corresponding to the training scenario to be created are entered. By providing "location" information and "event" information to the base scenario, it is possible to select a highly realistic base scenario that is similar to the training scenario to be created. As a result, this contributes to improving the ease of creating training scenarios.

[0147] In step S304, the base scenario editing unit 30i calls and refers to the selected base scenario from the base scenarios stored in the storage unit 16, and then the process proceeds to step S306.

[0148] In step S306, the base scenario editing unit 30i extracts items that will be elements of the training scenario to be created based on the referenced base scenario and the message information that constitutes the base scenario. In other words, it extracts message information (unnecessary events, etc.) to be deleted from the base scenario. It also stores message information to be added to the base scenario in the storage unit. The information is extracted from the information stored in 16 and the information entered by the scenario creator.

[0149] In step S308, the base scenario editing unit 30i combines the extracted elements with the base scenario (selecting and selecting message information) to create a training scenario. By selecting and selecting message information for the virtual base scenario, the realism of the training scenario can be further improved, and the difficulty level of the training scenario can be easily adjusted, and the balance of the training content can be easily adjusted to match the proficiency level of the trainee, thereby creating a desired training scenario.

[0150] Then, in step S310, the scenario creation processing unit 30 checks whether the training scenario is complete. For example, the training scenario creation unit 30f checks whether the scenario creation work is complete by checking whether the "Scenario Creation Complete" button has been operated.

[0151] If the answer is "No" in step S310, that is, if the training scenario is still being created (edited), the process proceeds to step S306, and the message information extraction process is repeated.

[0152] In step S310, if the answer is "Yes," that is, if the creation (editing) of the training scenario is complete, the training scenario creation unit 30f formats it as a new training scenario that can be reproduced by the scenario training processing unit 28, stores it in the memory unit 16, and temporarily terminates this flow.

[0153] In this way, the scenario creation processing unit 30 of this embodiment can easily create training scenarios that respond to events that have never occurred before by referring to a base scenario created in advance through machine learning and editing the base scenario. As a result, it is possible to easily and efficiently create training scenarios that are appropriate for adjusting the difficulty level of newly created training scenarios and for the proficiency level of the trainee. Furthermore, creating training scenarios in this way can contribute to reducing the cost of creating training scenarios, reducing the effort required for training to respond to equipment abnormalities, and shortening the time required to start training.
