MODE FOR CARRYING OUT THE INVENTION

[0010] Hereinafter, embodiments of this disclosure will be described with reference to the drawings. In this disclosure, the drawings are associated with one or more embodiments. Also, in all the drawings, the same components are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0011] <<FIRST EMBODIMENT>> FIG. 1 is a functional block diagram showing an overview of an information processing apparatus 10. FIG. 2 is a flowchart showing an example of the processing flow executed by the information processing apparatus 10.

[0012] As shown in Figure 1, the information processing device 10 includes a map control unit 11, a specific unit 12, and a route map control unit 13. These functional units execute the processes shown in the flowchart of Figure 2.

[0013] In S10, the map control unit 11 displays a map screen, including part or all of the map showing the route's location, on each of the multiple terminal devices, and switches the range of the map displayed on the map screen for each terminal device. In S11, the identification unit 12 identifies the display route range, which is the range of routes included in the map screen displayed on each terminal device. In S12, the route map control unit 13 generates a route map screen showing the display route range for each terminal device on a route map showing the connections between routes, and displays it on each of the multiple terminal devices.

[0014] In this manner, the information processing device 10 displays a map screen on the terminal device that includes part or all of a map showing the location of the route. The information processing device 10 also displays a route map screen on the terminal device that includes a route map showing the connections between the routes. A monitor monitoring the route can monitor the route and its surroundings based on the map screen and the route map screen. For example, the monitor can switch between displaying the map screen and the route map screen. The monitor can then view the desired information at the desired time and perform monitoring work. With such an information processing device 10, the monitor can appropriately utilize different information, such as the map screen and the route map screen, to perform monitoring. As a result, improvements in the efficiency and accuracy of monitoring work can be expected.

[0015] Incidentally, the scope of the route can be extensive. For this reason, route monitoring may involve multiple monitors dividing the task among themselves. Therefore, the information processing device 10 displays a map screen on each of the multiple terminal devices and switches the map area displayed on the map screen for each terminal device. In this case, each monitor can display the map of the area they are monitoring on the map screen and perform their monitoring work. That is, one monitor can display and monitor a part of the route on the map screen, and another monitor can display and monitor another part of the route on the map screen. As a result, multiple monitors can divide the task of monitoring the route.

[0016] Furthermore, when multiple monitors share the task of monitoring a route, information sharing among them is necessary. By properly sharing information, it is possible to eliminate duplicate monitoring, such as multiple monitors monitoring the same location.

[0017] The information processing device 10 has a function to assist in such information sharing. Specifically, the information processing device 10 has a function to identify the displayed route range, which is the range of routes included in the map screen displayed on each terminal device. The range of routes displayed on a terminal device can be considered as the range of routes being monitored by the monitor operating that terminal device. This function makes it possible to identify the range of routes being monitored by the monitor operating each terminal device with high accuracy.

[0018] The information processing device 10 has the function of generating a route map screen that shows the range of routes displayed on each terminal device (displayed route range) on the route map and displaying it on each terminal device. Based on the information shown on the route map screen, each monitor can understand which parts of the route other monitors are displaying and monitoring on their terminal devices. By displaying information on the route map that shows the range of routes monitored by each monitor, monitors can intuitively understand the overlap of monitoring ranges of multiple monitors and the distribution of monitoring ranges of multiple monitors.

[0019] As a comparative example of a means of identifying the range of routes monitored by an observer, a method of receiving declarations from each observer can be considered. In this case, observers would need to input the range of routes they are monitoring, which is time-consuming. Furthermore, the range of monitoring can change dynamically. In such cases, observers would need to perform this input work every time the range of monitoring changes, which is very time-consuming. As described above, the information processing device 10 identifies the range of routes monitored by an observer as the range of routes included in the map screen displayed on each terminal device, making it possible to identify the range of routes monitored by an observer without imposing any burden of input on the observer.

[0020] Such an information processing device 10 can be used to develop technology for monitoring routes.

[0021] <<Second Embodiment>> <Overview> The information processing device 10 of the second embodiment is a concrete implementation of the configuration of the information processing device 10 of the first embodiment. It will be described in detail below.

[0022] <Hardware Configuration> First, an example of the hardware configuration of the information processing device 10 will be described. Each functional unit of the information processing device 10 is realized by any combination of hardware and software. Those skilled in the art will understand that there are various variations in the implementation method and the device. The software includes programs that are pre-installed at the time of shipment of the device, as well as programs downloaded from recording media such as CDs (Compact Discs) or from servers on the Internet.

[0023] Figure 3 is a block diagram illustrating the hardware configuration of the information processing device 10. As shown in Figure 3, the information processing device 10 includes a processor 1A, memory 2A, input / output interface 3A, peripheral circuitry 4A, and bus 5A. Peripheral circuitry 4A includes various modules. The information processing device 10 does not necessarily have peripheral circuitry 4A. The information processing device 10 may also be composed of multiple physically and / or logically separated devices. In this case, each of the multiple devices may have the above hardware configuration.

[0024] Bus 5A is a data transmission path for the processor 1A, memory 2A, peripheral circuits 4A, and input / output interface 3A to send and receive data to and from each other. Processor 1A is a processing unit such as a CPU (Central Processing Unit) or GPU (Graphics Processing Unit). Memory 2A is a memory such as RAM (Random Access Memory) or ROM (Read Only Memory). Input / output interface 3A includes interfaces for acquiring information from input devices, external devices, external servers, external sensors, cameras, etc., and interfaces for outputting information to output devices, external devices, external servers, etc. Input / output interface 3A also includes interfaces for connecting to communication networks such as the Internet. Input devices include, for example, keyboards, mice, microphones, physical buttons, touch panels, etc. Output devices include, for example, displays, projectors, speakers, printers, mailers, etc. Processor 1A can issue commands to each module and perform calculations based on their calculation results.

[0025] <Functional Configuration> Next, the functional configuration of the information processing device 10 will be described in detail. Figure 4 is an example of a functional block diagram of the information processing device 10. As shown in the figure, the information processing device 10 has a map control unit 11, a specific unit 12, a route map control unit 13, and a switching unit 14.

[0026] The map control unit 11 displays a map screen on each of the multiple terminal devices, which includes part or all of a map showing the location of the route. The map control unit 11 then switches the range of the map displayed on the map screen for each terminal device.

[0027] A "terminal device" is a device operated by a monitor. Examples of terminal devices include, but are not limited to, personal computers, tablet devices, smartphones, wearable devices, and dedicated monitoring devices. Multiple terminal devices are provided. Multiple monitors use separate terminal devices to monitor. A terminal device for the supervisor to oversee multiple monitors may also be provided. A terminal device for the supervisor is not required. The supervisor can understand the monitoring status of multiple monitors based on the information displayed on the terminal device. In the following, it is assumed that terminal devices for monitors and terminal devices for supervisors are provided.

[0028] The terminal device and the information processing device 10 are configured to communicate with each other. For example, the information processing device 10 functions as a server, and the terminal device functions as a client terminal. The information processing device 10 can provide information (such as a map screen or a route map screen) to the terminal device in response to a request from the terminal device, and can display the provided information on the terminal device.

[0029] A "route" is a predetermined path or route. Examples of routes include, but are not limited to, expressways, toll roads, general roads, bus routes, train tracks, freight routes, shipping routes, and aircraft routes.

[0030] A "monitor" is someone who monitors a railway line. For example, a member of a monitoring center that monitors a railway line becomes a monitor and monitors the line. A monitoring center is a facility that collects various information about a railway line and performs monitoring duties based on the collected information. Examples of monitoring centers include, but are not limited to, control centers for expressways and general control rooms for trains. The purpose of monitoring a railway line is to detect accidents and troubles, etc.

[0031] A "map" is a diagram (image) that shows the state of a region, and can be realized, for example, using GIS (Geographic Information System) data. GIS data is composed of various layers overlaid on top of base data. The location of a route may be shown in the base data or in other layers.

[0032] The "map screen" is the screen displayed on the terminal device's display. The map screen includes part or all of the map described above. In other words, the map screen displays part or all of the map described above. Displaying part of the map means displaying a portion of the area included in the map. Displaying the entire map means displaying all of the area included in the map.

[0033] Figure 5 shows an example of a map screen. The map screen shown includes a portion of the map. The map screen shows the location of highways (routes). The mark M in the upper right of Figure 5 will be explained later.

[0034] The map screen is configured as a UI (user interface) screen. Monitors and supervisors can perform various inputs through the map screen. For example, monitors and supervisors can change the scale of the map displayed on the map screen, or change parts of the map displayed on the map screen to other parts.

[0035] "Switching the map range displayed on the map screen" is achieved by changing the scale of the map displayed on the map screen or by changing a part of the map displayed on the map screen to another part. The map control unit 11 displays the map screen on each terminal device and can receive instructions from each terminal device to change the scale of the map or change a part of the map displayed on the map screen to another part. In one example, the terminal device receives the input of such instructions through user operation by a monitor or supervisor. The terminal device then transmits the input instructions to the information processing device 10. The map control unit 11 can switch the map range displayed on the map screen of each terminal device in response to the instructions. The map control unit 11 can receive such operations for each terminal device and perform the switching for each terminal device. This switching process by the map control unit 11 can be achieved using widely known map data provision technology.

[0036] Returning to Figure 4, the specific unit 12 identifies the display route range.

[0037] The "displayed route range" is the range of routes included in the map screen displayed on each terminal device. In other words, the displayed route range is the range of routes displayed on the map screen of each terminal device. The displayed route range can be represented using identification information that identifies each of multiple points along the route. By identifying multiple points along the route, the range of the route enclosed by those points can be represented. The displayed route range can be represented using this method.

[0038] Incidentally, on roads such as expressways, multiple reference points are predetermined along the route, and distance markers indicating the distance (reference value) from a base point on the route to each reference point are installed at each reference point. Multiple reference points can be identified from each other by the distance (reference value) from the base point on the route to each reference point. Therefore, the distance (reference value) from the base point on the route can be used as identification information for each of the multiple reference points.

[0039] Therefore, in one example, the displayed route range can be represented using these reference points and reference values. First, the identification unit 12 identifies multiple reference points located at the furthest ends of the route included in the map screen. If the route included in the map screen is a single route without branches, the identification unit 12 identifies two reference points located at the furthest ends of that route included in the map screen. On the other hand, if the route included in the map screen is a route with branches, the identification unit 12 identifies three or more reference points located at the furthest ends of that route included in the map screen.

[0040] The identification unit 12 then outputs the reference value of each of the identified reference points as information indicating the range of the displayed route.

[0041] Information indicating the location of reference points along the route and the reference value of each reference point is stored in a predetermined storage device. The specific unit 12 can perform the above processing based on this information. The predetermined storage device may be provided within the information processing device 10, or it may be provided within an external device configured to communicate with the information processing device 10. The same premise regarding the predetermined storage device applies below.

[0042] In the example shown in Figure 5, a single route (highway) extending from left to right is displayed. In this case, the identification unit 12 identifies both ends of the illustrated highway, specifically the reference point located at the far right of the screen (not shown) and the reference point located at the far left of the screen (not shown). The identification unit 12 then outputs the reference values ​​of each of the two identified reference points as information indicating the range of the displayed route.

[0043] As a variation, instead of using the above-mentioned reference points and reference values, latitude and longitude information may be used. In this example, the specific unit 12 indicates the locations of multiple ends of the route included in the map screen using latitude and longitude information. The specific unit 12 then outputs the latitude and longitude information of these multiple ends as information indicating the range of the displayed route.

[0044] By the way, if the scope of the routes monitored by each monitor is shared, there may be a need to "know the latest monitoring scope of each monitor." This information would allow monitors and supervisors to understand what scope each monitor is currently monitoring.

[0045] However, monitors can dynamically switch the map range displayed on the map screen. Therefore, if the monitor's monitoring range is determined based on the display at a specific moment in time, the reliability of that determination may be somewhat low. Thus, there may be a need to know the monitoring range of each monitor within a specified time period.

[0046] Therefore, the identification unit 12 can identify the display route range for each terminal device using at least one of the following methods and input the result to the route map control unit 13.

[0047] "A method tailored to the need to know the latest monitoring scope." In this method, the identification unit 12 identifies the range of routes included in the map screen displayed on each terminal device, based on the latest map screen displayed on each terminal device. The identification unit 12 then inputs the result to the route map control unit 13.

[0048] For example, the identification unit 12 can acquire the map screen (latest map screen) displayed on each terminal device at the time it performs the process of identifying the range of routes included in the map screen. Then, based on the acquired map screen, the identification unit 12 can identify the range of routes included in the map screen (displayed route range). The method for identifying the range of routes included in the map screen is as described above.

[0049] Furthermore, the monitor does not necessarily keep the map screen displayed on the terminal device at all times; they can switch between the map screen and other screens. In other words, there may be times when the map screen is not displayed on the terminal device. In this case, there may be terminal devices that are not displaying the map screen at the time of processing to identify the range of routes included in the map screen. In such terminal devices, the identification unit 12 may identify the range of routes included in the map screen based on the most recent map screen displayed in the past.

[0050] A method tailored to the need to "know the monitoring scope within the most recent specified time period." In this method, the specific unit 12 processes each of the multiple map screens displayed within the most recent predetermined time for each terminal device and identifies the range of routes included in each map screen.

[0051] In one example, a predetermined time interval (e.g., every t seconds) is defined as the sampling timing. The identification unit 12 then processes each of the multiple map screens displayed on the terminal device at each of the multiple sampling timings to identify the range of routes included in each map screen. The identification unit 12 then stores the identification results in a predetermined storage device. When the identification unit 12 performs the process of identifying the monitoring range within the most recent predetermined time, it identifies the sampling timing included in the most recent predetermined time. The identification unit 12 then obtains information from the above information stored in the predetermined storage device that indicates the range of routes included in each of the multiple map screens displayed on the terminal device at each of the identified multiple sampling timings.

[0052] The identification unit 12 then identifies a route range for each terminal device that satisfies one of the following conditions. The identification unit 12 then inputs the route range identified for each terminal device into the route map control unit 13 as the route range to be displayed on each terminal device. • The range (logical OR, union) displayed on at least one of the multiple map screens displayed on the terminal device at each of the identified sampling timings. • The range displayed on a predetermined percentage or more of the map screens among the multiple map screens displayed on the terminal device at each of the identified multiple sampling timings. • The range (logical AND, intersection) displayed on all map screens among the multiple map screens displayed on the terminal device at each of the identified sampling timings.

[0053] Here, we will explain an example of the processing performed by the identification unit 12, using an example where the displayed route range is shown by the reference value of the reference point described above. Here, we will explain the process of identifying "the range of routes (logical OR, union) that were displayed on at least one of the multiple map screens displayed on the terminal device at each of the multiple sampling timings identified."

[0054] First, the identification unit 12 identifies the minimum and maximum values ​​from the reference values ​​of reference points included in each of the multiple map screens displayed within the most recent predetermined time for each terminal device. The multiple map screens displayed within the most recent predetermined time are the map screens displayed on the terminal device at each of the multiple sampling timings included in the most recent predetermined time. Then, the identification unit 12 identifies the range from the identified minimum value to the identified maximum value as the display route range for each terminal device. In this case, the identification unit 12 inputs the identified minimum and maximum values ​​to the route map control unit 13 as information indicating the display route range for each terminal device.

[0055] Returning to Figure 4, the route map control unit 13 displays a route map screen showing the connections between routes on each of the multiple terminal devices.

[0056] A "route map" is a diagram (image) that shows the connections between routes. The route map contains information about the entire route that each monitoring center is responsible for monitoring. The route map shows one or more routes that make up a route. The route map also shows the relative positions of facilities and equipment that exist on the route. Facilities and equipment vary and may differ depending on the type of route. For example, if the route is a highway, examples of facilities and equipment include, but are not limited to, interchanges, junctions, service areas (parking areas), surveillance cameras, and distance markers for the reference points mentioned above. If the route is of other types, examples include, but are not limited to, bus stops, train stations, level crossings, airports, and overnight parking areas.

[0057] Incidentally, the maps on the map screen mentioned above also show routes. And the maps may also show the route information as described above. In other words, maps and route maps are similar in that they are images that contain information about routes. However, route maps are diagrams specifically designed to convey particular information about routes, and they show that specific information about routes more clearly and concisely, omitting unnecessary information. For this reason, maps and route maps differ in their details. For example, maps accurately show the shape of the route (presence or absence of curves, shape of curves, radius of curvature of curves, etc.). On the other hand, route maps do not need to show the exact shape of the route. For example, route maps may simply show the connections of routes with straight lines, predetermined curves, or circular lines. Also, in addition to route information, maps show information about the surrounding area (information about facilities not on the route, etc.). Route maps do not need to show information other than route information.

[0058] In one example, the route map is configured as one layer of the GIS data that makes up the map described above. Note that the route map may be configured by other means. When the route map is configured as one layer of the GIS data, the route map is composed of a non-transparent layer. That is, when the route map is displayed, the information of the lower layers is hidden, and only the information of the route map layer is visible.

[0059] The "route map screen" is the screen displayed on the terminal device's display. The route map screen includes the route map described above. In other words, the route map screen displays the route map described above. The route map screen includes the entire route map. That is, the route map screen always displays the entire route map, i.e., the entire route that each monitoring center is responsible for monitoring.

[0060] Figures 6 and 7 show examples of route map screens. The route map screens shown represent a highway (route). The route map screens show the relative positions of multiple interchanges and multiple reference points. The numbers "40 to 80" in Figure 6 and "50 to 130" in Figure 7 represent the reference values ​​for each of the multiple reference points.

[0061] The route maps shown are merely examples and are not limited to this example. Route maps may be presented in a simpler form. For example, the examples shown separately indicate the up and down lines, but this distinction may be omitted. The mark Q in the upper right of Figures 6 and 7 will be explained later.

[0062] The route map screen is configured as a user interface (UI) screen. Supervisors and monitors can perform various inputs through the route map screen.

[0063] The route map control unit 13 can display characteristic information on the route map screen by performing at least one of the following display methods 1 to 7.

[0064] “Display method 1” The route map control unit 13 can generate a route map screen that displays monitoring range information on the route map as described above, and display it on each of the multiple terminal devices.

[0065] The "monitoring range information" indicates the display route range identified by the specific unit 12 for each of the multiple terminal devices. Such monitoring range information can be considered to indicate the range of routes being monitored by the monitor operating each of the multiple terminal devices.

[0066] Figure 8 shows an example of a route map screen displaying monitoring range information R. The monitoring range information R shown is represented by a frame, which indicates the display route range for each terminal device. The area enclosed by each frame is the display route range for each terminal device. Note that the monitoring range information R may be other than a frame. For example, the display route range for each terminal device may be indicated by line segments displayed along the route.

[0067] In the example shown in Figure 8, the display route range for each of the three terminal devices is indicated by three frames. In the example in Figure 8, information labeled "A," "B," and "C" is displayed in association with each frame. This information identifies the monitor operating each terminal device. For example, the monitor operating each terminal device is identified based on the login information entered into each terminal device when logging into the information processing device 10 system by operating each terminal device. The route map control unit 13 identifies the monitor operating each terminal device by means such as this, and realizes the display of information labeled "A," "B," and "C" as shown in Figure 8. The information used to identify the monitor displayed may be the monitor's name, a serial number, or something else. In addition, the route map control unit 13 may display information identifying each terminal device (such as the serial number of the terminal device) in association with each frame, either in lieu of or in addition to the information identifying the monitor.

[0068] “Display method 2” Multiple monitors may be pre-assigned to groups. Information indicating which monitor belongs to each group may be stored in a predetermined storage device. In this case, the route map control unit 13 refers to this information to identify the group to which the monitor operating each terminal device belongs. The route map control unit 13 may then display information identifying the group to which the monitor belongs, linked to each monitoring range information R (frame, line segment, etc.), in place of or in addition to the information identifying the monitor or the information identifying each terminal device.

[0069] “Display method 3” The route map control unit 13 may vary the display style (color, line type, line thickness, etc.) of the monitoring range information R (frames, line segments, etc.) for each monitor, terminal device, or group. By doing so, a monitor viewing the route map screen can intuitively identify multiple monitoring range information R and easily understand which monitor (which terminal device or which group) each monitoring range information R represents.

[0070] “Display method 4” The route map control unit 13 may vary the display manner (color, line type, line thickness, etc.) of the monitoring range information R (frames, line segments, etc.) according to the fluctuation status of the displayed route range indicated by each monitoring range information R. For example, the route map control unit 13 may display monitoring range information R where the displayed route range has not changed (or the amount of change is below a threshold) and monitoring range information R where the displayed route range has changed (or the amount of change is greater than a threshold) in different display manners. In this way, monitors who view the route map screen can easily grasp whether the most recent monitoring range by each monitor is almost fixed or fluid. The amount of change may be obtained, for example, as a statistical value of the difference (distance of non-overlapping parts, etc.) between the displayed route range at a certain point in time during the immediate vicinity and the displayed route range at each of several other points in time, or it may be obtained by other means. The statistical value may be the mean, maximum, minimum, median, mode, etc., but is not limited to these.

[0071] “Display method 5” The route map control unit 13 may accept input to select one monitoring range information R on the route map screen. Then, in response to the input, the route map control unit 13 may transmit predetermined information to the terminal device that received the input and display it on the display.

[0072] The specified information is information related to the terminal device corresponding to the selected monitoring range information R. The terminal device corresponding to the selected monitoring range information R is a terminal device identified by the identification unit 12 as displaying the range of the route indicated by the selected monitoring range information R on the map screen. For example, the route map control unit 13 may acquire the screen currently displayed on the terminal device corresponding to the selected monitoring range information R and send that screen to the terminal device that received the input to select the monitoring range information R for display. Such a process of displaying the screen displayed on the display of one terminal device on the display of another terminal device can be realized, for example, by using a widely known mirroring function.

[0073] “Display method 6” Some areas included in the map do not have any routes. Therefore, the map screen displayed on the terminal device may not include any routes. In this case, the identification unit 12 inputs information to the route map control unit 13 to indicate this. The route map control unit 13 can then link to the terminal device (or the monitor or group operating it) that is displaying a map screen that does not include any routes and display other information in place of the monitoring range information R.

[0074] In one example, as shown in Figure 9, the route map control unit 13 can display the map screen S displayed on a terminal device that is displaying a map screen that does not include any routes. Based on the fact that map screen S is displayed, the monitor can understand that "the terminal device is displaying a map screen that does not include any routes." In addition, the monitor and supervisor can understand the content of the map screen displayed on the terminal device based on the content of map screen S.

[0075] “Display method 7” The route map control unit 13 may display the map screen S instead of the monitoring range information R when other conditions are met. For example, the map screen S may be displayed in association with a terminal device (or the monitor or group operating it) that is displaying the map screen with a zoom level (display magnification) below a threshold. When the zoom level is below a threshold, a fairly wide area is displayed on the map screen. In this case, it can be considered that the monitor is not monitoring a specific range of the route, but is observing a wide area comprehensively with some intention. The map screen S may also be displayed when it is not recognized that a specific range of the route is being monitored. Based on the fact that the map screen S is displayed, the monitor can understand that "the terminal device is displaying a map screen that includes a wide range of the route." In addition, the monitor and supervisor can understand the content of the map screen displayed on the terminal device based on the content of the map screen S.

[0076] Returning to Figure 4, the switching unit 14 switches the screen displayed on each terminal device between the map screen and the route map screen. The switching unit 14 can perform this switching based on user input. The switching unit 14 can receive user input for each terminal device. Based on the user input received by each terminal device, the switching unit 14 can switch the screen displayed on each terminal device.

[0077] In one example, as shown in Figure 5, a screen switching mark M is displayed on the map screen. When the switching unit 14 receives an operation on mark M, it can switch the screen displayed on the terminal device that received the operation from the map screen to the route map screen accordingly.

[0078] In one example, as shown in Figures 6 to 9, a mark Q for screen switching is displayed on the route map screen. When the switching unit 14 receives an operation on mark Q, it can switch the screen displayed on the terminal device that received the operation from the route map screen to the map screen accordingly. In the map screen immediately after the switch in response to the operation, only a part of the map, representing the default range, may be displayed. Alternatively, the entire map may be displayed on the map screen immediately after the switch in response to the operation. Furthermore, when the display is switched from the map screen to the route map screen in response to a user operation, the map control unit 11 may store the range of the map that was displayed on the map screen immediately before the switch in a predetermined storage device. Then, in the map screen immediately after the switch in response to the operation on mark Q on the route map screen, the range of the map that was displayed on the map screen immediately before switching to the route map screen may be displayed.

[0079] Next, an example of the processing flow of the information processing device 10 will be explained using the flowchart in Figure 10. Note that the purpose here is to explain just one example of the processing flow. Details of each process have been described above, so explanations will be omitted here as appropriate. Here, we will explain the processing flow for switching the screen display on a single terminal device.

[0080] First, when processing begins, the information processing device 10 displays a map screen on the terminal device (S20). Next, when the information processing device 10 receives input to change the range of the map to be displayed on the map screen (Yes in S21), it changes the range of the map to be displayed on the map screen (S22).

[0081] Furthermore, when the information processing device 10 receives input to switch the displayed screen to the route map screen (Yes in S23), it displays the route map screen on the terminal device (S24). Subsequently, when the information processing device 10 receives input to switch the displayed screen to the map screen (Yes in S26), it displays the map screen on the terminal device (S20).

[0082] From this point onward, the information processing device 10 repeats the same process. In this example, the map screen was displayed on the terminal device at the start of processing, but the route map screen may also be displayed on the terminal device at the start of processing. In this case, processing will start from S24.

[0083] <Effects and Effects> According to the information processing device 10 of the second embodiment, the same effects and advantages as those of the information processing device 10 of the first embodiment can be achieved.

[0084] Furthermore, as shown in Figure 8, the information processing device 10 can generate a route map screen on which monitoring range information R, indicating the display route range of each terminal device, is displayed on the route map, and display this screen on the terminal device. By viewing such a route map screen, monitors and supervisors can intuitively grasp the range that each monitor is monitoring. In addition, by viewing such a route map screen, monitors and supervisors can intuitively grasp the overlap of monitoring ranges of multiple monitors, the distribution of monitoring ranges of multiple monitors, and so on.

[0085] Furthermore, the information processing device 10 can display characteristic information on the route map screen by executing at least one of the display methods 1 to 7 described above. This enables the realization of the various effects and benefits described above.

[0086] For example, the information processing device 10 can receive input to select one monitoring range information R from one terminal device. Then, in response to this selection input, the information processing device 10 can acquire the screen displayed on the terminal device corresponding to the selected monitoring range information R and display the acquired screen on the terminal device that received the input to select the monitoring range information R. With an information processing device 10 equipped with such a mirroring function, monitors and supervisors can understand the information that other monitors are displaying on their screens and monitoring. As a result, information sharing is promoted.

[0087] Furthermore, the information processing device 10 can receive input to select one terminal device to view the screen using the mirroring function on the route map screen displaying the monitoring range information R as shown in Figure 9. Monitors and supervisors can select the terminal device on which they wish to view the displayed screen while checking the displayed route range on each terminal device.

[0088] Furthermore, the information processing device 10 can identify the display route range of each terminal device using a method that meets the need to "know the latest monitoring range of each monitor." It can also identify the display route range of each terminal device using a method that meets the need to "know the monitoring range of each monitor within the most recent predetermined time." Because the information processing device 10 can identify the display route range of each terminal device using methods that meet these various needs, it becomes possible to provide information that meets those needs.

[0089] <<Third Embodiment>> The information processing device 10 of the third embodiment can perform characteristic processing using a map screen and a route map screen when it detects the occurrence of an event on a route. This will be described in detail below.

[0090] "Characteristic processing in map screens" The map control unit 11 can perform the following operations. When the map control unit 11 detects the occurrence of an event on a route, it identifies the location where the event occurred. Next, the map control unit 11 determines whether the location where the event occurred is displayed on each terminal device that is displaying the map screen. Then, the map control unit 11 displays information indicating the occurrence of the event on the map screen for terminal devices where the location where the event occurred is not displayed. On the other hand, the map control unit 11 may also display information indicating the occurrence of the event at the location where the event occurred on the map for terminal devices where the location where the event occurred is displayed.

[0091] First, we will explain the means for detecting events occurring on the route and identifying the location of the event. In one example, when an event occurs, event information is input to the information processing device 10 from an external device. Alternatively, an operator may input event information to the information processing device 10 when an event occurs.

[0092] Event occurrence information indicates the location where the event occurred. The event occurrence location may be indicated by the reference value of the reference point described in the second embodiment, or by latitude and longitude information. In addition, the event occurrence location may be expressed using facilities or equipment located along the route, such as "between facility A and facility B". In addition, the event occurrence location may be expressed using the name of a city or town, street address, etc.

[0093] Event occurrence information may also indicate the type and severity of the event. Examples of event types include, but are not limited to, accidents, falling objects, road malfunctions, and traffic congestion. Severity may be determined by a human or by a computer using predetermined calculations. The computer can determine severity based on the attributes of the event occurrence location (e.g., inside a tunnel, near an interchange) and the type of event. In one example, a calculation model is generated in advance that takes the attributes of the event occurrence location and the type of event as input and outputs severity. The calculation model may be a calculation formula or may include a correspondence table showing the relationship between input and output values. The computer can calculate severity using this calculation model. In one example, the information processing device 10 can calculate severity. In this case, the information processing device 10 can identify the attributes of the event occurrence location using map information.

[0094] There are various methods for determining whether the event location is displayed on each terminal device that is displaying the map screen. For example, the map control unit 11 can use the display route range described in the second embodiment. In this example, the map control unit 11 determines whether the event location is included within the display route range of each terminal device. In this example, it is preferable to identify the display route range of each terminal device using the method described in the second embodiment that "meets the need to know the latest monitoring range".

[0095] Figure 11 shows an example of displaying information indicating an event has occurred on the map screen for a terminal device where the event location is not displayed. In the example in Figure 11, a highway (route) is shown on the map screen. The event location is not included within the range of the route shown on the map screen. In such a case, the map control unit 11 displays information indicating an event has occurred on the map screen. In the example in Figure 11, the map control unit 11 displays a mark M indicating an event in the upper right corner of the map screen. This mark M can have the same function as the mark M shown in the example in Figure 5. That is, when the switching unit 14 receives an operation on the mark M in Figure 11, it can switch the screen displayed on the terminal device that received the operation from the map screen to the route map screen accordingly. In the example in Figure 11, when an event occurs, the display manner of the mark M for such screen transition is changed to notify the monitor that the event has occurred outside the range of the screen.

[0096] Furthermore, the map control unit 11 may change the display manner (color, shape, design, size, etc.) of the mark M depending on the type and importance of the event. In this way, the monitor can understand the type and importance of the event that is occurring based on the display manner of the mark M.

[0097] "Characteristic processing in the route map screen" The route map control unit 13 can perform the following operations. When the route map control unit 13 detects the occurrence of an event on the route, it identifies the location where the event occurred. Next, the route map control unit 13 displays the event occurrence information at the location on the route map corresponding to the location where the event occurred.

[0098] The means for detecting events occurring along the route and identifying the location of the event are as described above.

[0099] Figure 12 shows an example of a route map screen where event occurrence information N is displayed at the location corresponding to the event occurrence point on the route map. In the example in Figure 12, an "X" mark is displayed for event occurrence information N.

[0100] The route map control unit 13 may change the display manner (color, shape, design, size, etc.) of the event occurrence information N depending on the type and importance of the event. In this way, the monitor can understand the type and importance of the event that has occurred based on the display manner of the event occurrence information N. The display manner of the event occurrence information N may be different from or the same as the display manner of the mark M in the upper right corner of the map screen (see Figure 11) when an event occurs.

[0101] "A distinctive screen switching process" The switching unit 14 can switch the screen displayed on the terminal device that received the operation from the route map screen to the map screen in response to an operation on the event occurrence information N on the route map screen.

[0102] In this case, the map control unit 11 can, in response to an operation on the event occurrence information N, cause the terminal device that received the operation to display a map screen showing a portion of the map where the event occurred. That is, the map control unit 11 can generate a map screen focused on the event occurrence location and display it on the terminal device. In this map screen, the event occurrence location may be located in the center of the screen. In addition, the map screen may display the map at a predefined scale.

[0103] The map control unit 11 may differentiate the displayed content on the map screen immediately after switching depending on whether the screen is switched in response to an operation on mark Q shown in Figure 12 or in response to an operation on event occurrence information N shown in Figure 12. An example of the process when switching the screen in response to an operation on mark Q is as described in the second embodiment. An example of the process when switching the screen in response to an operation on event occurrence information N is as described above.

[0104] When switching screens in response to an operation on Mark Q shown in Figure 12, the map control unit 11 may perform the "characteristic processing on the map screen" described above. That is, the map control unit 11 first determines the range of the map to be displayed on the switched map screen based on the processing described in the second embodiment. Next, the map control unit 11 determines whether the event occurrence location is displayed within the determined map range. Then, the map control unit 11 generates a map screen according to the result of that determination and displays it on the terminal device.

[0105] Furthermore, the switching unit 14 can switch the screen displayed on the terminal device that received the operation from the map screen to the route map screen in response to an operation on the mark M (see Figure 11) on the map screen. In this case, the identification unit 12 can generate the route map screen shown in Figure 12 and display it on the terminal device that received the operation.

[0106] Other configurations of the information processing device 10 can be the same as those in the first and second embodiments.

[0107] According to the information processing device 10 of the third embodiment, the same effects and advantages as those of the information processing device 10 of the first and second embodiments can be achieved.

[0108] Furthermore, when the information processing device 10 detects an event occurring on the route, it can generate the characteristic map screen described above and display it on the terminal device. The monitor can then understand the status of the event that occurred based on this map screen.

[0109] Furthermore, when the information processing device 10 detects an event occurring on the route, it can generate the characteristic route map screen described above and display it on the terminal device. The monitor can then understand the status of the event that occurred based on this route map screen.

[0110] Furthermore, when the information processing device 10 detects an event occurring on the route, it can switch between the map screen and the route map screen using the characteristic method described above. The monitor can quickly view and check the information they want to confirm when an event occurs.

[0111] <<Fourth Embodiment>> The information processing device 10 of the fourth embodiment has the function of receiving input to specify a portion of a route on a route map screen and notifying other terminal devices of the specified portion. This will be described in detail below.

[0112] The route map control unit 13 receives input from a single terminal device to specify a portion of a route on the route map screen that shows the route range displayed for each terminal device. There are various means for receiving such input, and it can be implemented using widely known technologies. For example, as shown in Figure 13, the route map control unit 13 may receive input to specify a portion of a route by drag operation or the like. In the example in Figure 13, the route map control unit 13 receives input to specify a range enclosed by frame V.

[0113] When the route map control unit 13 receives input from one terminal device specifying a range of a route, it can output information indicating the specified range to other terminal devices. For example, the route map control unit 13 may display information indicating the specified range (e.g., frame V) on the route map screen displayed on each terminal device, as shown in Figure 13.

[0114] Furthermore, when the route map control unit 13 receives an input from one terminal device specifying a portion of the route, it may output information indicating the specified portion to all other terminal devices.

[0115] In addition, the route map control unit 13 may, upon receiving an input from one terminal device specifying a range of a route, output information indicating the specified range to other terminal devices. In this case, the route map control unit 13 can receive an input from the terminal device that received the input specifying a range of a route, further specifying a terminal device to output information indicating the specified range. The route map control unit 13 can then output information indicating the specified range to the specified terminal device.

[0116] Other configurations of the information processing device 10 can be the same as those of the first to third embodiments.

[0117] According to the information processing device 10 of the fourth embodiment, the same effects and advantages as those of the information processing device 10 of the first to third embodiments can be achieved.

[0118] Furthermore, the information processing device 10 has a function to accept input specifying a portion of a route on the route map screen and to notify other terminal devices of the specified portion. With such an information processing device 10, monitors and supervisors can use this function to notify designated monitors of the area to be monitored. In other words, monitors and supervisors can use this function to specify an area to be monitored on the route map screen and notify designated monitors of the specified area.

[0119] Furthermore, as shown in Figure 13, the information processing device 10 can accept input to specify a portion of a route on the route map screen displaying the monitoring range information R. Based on the monitoring range information R displayed on the route map screen, monitors and supervisors can understand the ranges being monitored by multiple monitors and then determine the range to be monitored by the designated monitor. With such an information processing device 10, it is possible to efficiently and accurately determine the range to be monitored by a predetermined monitor.

[0120] <<Fifth Embodiment>> The information processing device 10 of the fifth embodiment has a memo function that utilizes a route map screen. Supervisors and monitors can share information using this memo function. This will be explained in detail below.

[0121] The route map control unit 13 accepts input from a single terminal device to register a memo linked to a point on the route or monitoring range information on the route map screen. In other words, the route map control unit 13 accepts input specifying one point on the route or one monitoring range information on the route map screen. Then, the route map control unit 13 accepts input of a memo to be registered linked to the specified point or monitoring range information.

[0122] A memo may contain at least one of the following: text information, image information, and audio information. Text information consists of letters, numbers, symbols, etc. Image information is a concept that includes still images and moving images. Audio information is information that records audio.

[0123] Then, as shown in Figure 14, the route map control unit 13 can display a route map screen on a terminal device that shows information B indicating that a memo has been registered, linked to a location where a memo is registered or to monitoring range information R where a memo is registered. When the route map control unit 13 receives an operation on information B indicating that a memo has been registered, it can display the contents of the memo on the terminal device that received the operation.

[0124] The route map control unit 13 can display a route map screen showing information B indicating that a memo has been registered, as shown in Figure 14, not only on the terminal device that registered the memo, but also on other terminal devices. When the route map control unit 13 receives an operation regarding information B indicating that a memo has been registered, it can display the contents of the memo on the terminal device that received the operation. Therefore, the contents of the memo can be viewed not only by the monitor or supervisor who registered the memo, but also by other monitors and supervisors.

[0125] Other configurations of the information processing device 10 can be the same as those of the first to fourth embodiments.

[0126] According to the information processing device 10 of the fifth embodiment, the same effects and advantages as those of the information processing device 10 of the first to fourth embodiments can be achieved.

[0127] Furthermore, the information processing device 10 provides a memo function using the route map screen. Monitors and supervisors can use this function to register their own comments, etc. Monitors and supervisors can also use this function to share information with other monitors and supervisors.

[0128] <<Sixth Embodiment>> The information processing device 10 of the sixth embodiment has a function to further generate a seating chart showing the seating arrangements of multiple monitors and display it on a terminal device. This will be described in detail below.

[0129] The information processing device 10 can generate a seating chart screen and display it on each of the multiple terminal devices.

[0130] A "seating chart" is a diagram (image) showing the seat of each of several supervisors in a layout diagram of multiple seats. In one example, information identifying the supervisor at each seat is displayed, linked to each of the multiple seats shown in the layout diagram. The seating chart may also show the seat of the supervisor.

[0131] Multiple monitors may be pre-assigned to groups. Furthermore, information identifying the group to which the monitor at each seat belongs may be displayed, linked to each of the multiple seats. The means for identifying the group to which each monitor belongs is as described in the second embodiment.

[0132] In one example, the seating chart is configured as one layer of the GIS data that makes up the map described above. However, the seating chart may be configured by other means. When the seating chart is configured as one layer of the GIS data, the seating chart is composed of a non-transparent layer. That is, when the seating chart is displayed, the information of the lower layers is hidden, and only the information of the seating chart layer is visible.

[0133] The "seat screen" is the screen displayed on the terminal device's display. The seat screen includes a seating chart as described above. In other words, the seat screen displays a seating chart as described above.

[0134] The seat screen is configured as a user interface (UI) screen. Supervisors and managers can input various information through the seat screen.

[0135] Figure 15 shows an example of a seat screen. The illustrated seat screen displays a layout diagram of multiple seats, with each seat's associated mark indicating the group to which the seat's supervisor belongs. For example, each seat can be clicked to set a mark.

[0136] Furthermore, the information processing device 10 may display different seating arrangements (color, line type, line thickness, etc.) for multiple seats. For example, the information processing device 10 may distinguish between the seat of the supervisor operating a terminal device and other seats on a seating screen displayed on a terminal device.

[0137] Furthermore, as shown in the example in Figure 15, the information processing device 10 may have a function to register memos associated with each seat. The information processing device 10 can display a seat screen showing information B indicating that a memo has been registered, as shown in Figure 15, not only on the terminal device that registered the memo, but also on other terminal devices. When the information processing device 10 receives an operation on information B indicating that a memo has been registered, it can display the contents of the memo on the terminal device that received the operation. Therefore, the contents of the memo can be viewed not only by the supervisor or manager who registered the memo, but also by other supervisors and managers.

[0138] Other configurations of the information processing device 10 can be the same as those of the first to fifth embodiments.

[0139] According to the information processing device 10 of the sixth embodiment, the same effects and advantages as those of the information processing device 10 of the first to fifth embodiments can be achieved.

[0140] Furthermore, the information processing device 10 can generate a seat screen and display it on each of the multiple terminal devices. With such an information processing device 10, the seat location of each supervisor can be shared among multiple supervisors and managers via the seat screen.

[0141] <<Variation>> The following describes variations applicable to all embodiments.

[0142] As shown in Figure 16, the map control unit 11 can display information U on the map screen that indicates the display route range for each of the multiple terminal devices. The information U shown is a frame, but a certain range of the route may also be indicated by line segments or other means.

[0143] With such an information processing device 10, monitors and supervisors can understand the monitoring range of each of the multiple monitors by viewing the map screen.

[0144] Furthermore, when the map control unit 11 receives an operation to select one piece of information U (e.g., a hover operation), it may cause the terminal device that received the operation to display information about the monitor monitoring the selected displayed route range. This information about the monitor may include, but is not limited to, the monitor's name, the group they belong to, a photograph of them, their seat number, etc.
