  Hereinafter, a moving body information display device and a program according to embodiments will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram illustrating an example of a hardware configuration of the moving object information display apparatus according to the embodiment.

  The moving body information display device 1 is an information processing device that displays moving body information in the controlled airspace. As shown in FIG. 1, the moving body information display device 1 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. A computer configured control unit 10, a communication I / F 12, and an I / O device control unit 13 are connected by a bus 11.

  The control unit 10 performs overall control of the operation of the moving body information display device 1 by causing the CPU to develop the program 171 stored in the ROM or the storage unit 17 in the work area of the RAM and sequentially execute the program. Specifically, the control unit 10 sequentially executes a program 171 stored in the storage unit 17, thereby functioning as the monitoring information processing unit 101, the monitoring information display unit 102, and the monitoring information operation unit 103 (details will be described later). To achieve). The communication I / F 12 performs data communication with an external control information processing system such as an RDP (Radar Data Processing system) under the control of the control unit 10. Specifically, the communication I / F 12 is a position (latitude, longitude, altitude, error), speed, flight plan of a moving object (aircraft, ship, ground moving object) that moves within the controlled airspace from an external control information processing system. The moving body information such as is acquired at any time.

  An operation unit 14, a display unit 15, a printer 16, and a storage unit 17 are connected to the control unit 10 via an I / O device control unit 13. The operation unit 14 is a pointing device such as a keyboard, a mouse, or a touch panel stacked on the display unit 15 and accepts an operation from an operator (controller). The display unit 15 is a display device that displays display information from the control unit 10. The storage unit 17 is a storage device such as an HDD (Hard Disk Drive). The storage unit 17 stores various setting information in addition to the program 171 executed by the control unit 10. As the various setting information stored in the storage unit 17, when displaying a monitoring screen for displaying moving body information of the controlled airspace on the display unit 15, it is used for displaying a map of a building, topography, etc. There are building and terrain information files that describe the position of the building and terrain (latitude, longitude, altitude).

  FIG. 2 is a block diagram schematically illustrating a functional configuration of the moving object information display device 1 according to the embodiment. As shown in FIG. 2, the monitoring information processing unit 101 is a moving object that exists in the controlled airspace based on moving object information input from an external control information processing system and operation data input from the monitoring information operation unit 103. Display information of a two-dimensional monitoring screen for projecting symbols indicating each of the symbols in a state desired by the operator is generated. The monitoring information processing unit 101 outputs the generated display information to the monitoring information display unit 102. Specifically, the monitoring information processing unit 101 refers to a building / terrain information file in which the position of a building or terrain in the controlled airspace is described in addition to the moving object information and operation data, and the moving object in the controlled airspace, The building / terrain is projected onto the horizontal plane from vertically above, and display information for displaying a two-dimensional monitoring screen looking down from above is generated. In addition, about the direction which projects the moving body in a control airspace, you may project on a vertical surface from a horizontal direction other than projecting on a horizontal surface from right above. In this case, display information for generating a two-dimensional monitoring screen in which the controlled airspace is viewed from the horizontal direction is generated.

  The monitoring information display unit 102 displays the above-described two-dimensional monitoring screen on the display unit 15 based on the display information output from the monitoring information processing unit 101. The monitoring information operation unit 103 receives an operator input from the operation unit 14 when the operation unit 14 displays a two-dimensional monitoring screen on the display unit 15. Specifically, a pointing operation and various setting operations on the two-dimensional monitoring screen are received from the operator based on operations of a keyboard, a mouse, a touch panel, and the like in the operation unit 14. The monitoring information operation unit 103 outputs operation data indicating the received operation content to the monitoring information processing unit 101.

  Next, details of the operation of the moving body information display device 1 realized by the monitoring information processing unit 101, the monitoring information display unit 102, and the monitoring information operation unit 103 described above will be described. FIG. 3 is a flowchart showing an example of the operation of the moving object information display device 1.

  As shown in FIG. 3, when the program 171 is executed by the CPU of the control unit 10 and the process is started, the monitoring information processing unit 101 receives an input by the operator's operation from the monitoring information operation unit 103 (S11a). Based on the operation data output from the monitoring information operation unit 103, the display parameters for grouping and displaying moving objects existing in the controlled airspace are set (S11). Note that the display specifications in S11 may be set according to the operation of a setting button on the operation unit 14, and the setting may be changed at any timing of the operator.

  The operator's input in S11a is performed by displaying a setting image for performing various settings on the display unit 15 and receiving the operator's operation from the operation unit 14. In addition, the display parameters to be set in S11 are determined by setting the division of areas (ranges) to be grouped in the controlled airspace, setting the display / non-display of dividing lines dividing the areas, and selecting a plurality of divided areas. , Setting the range of the area where moving objects are grouped and displayed, setting the switching interval (cycle) when switching and displaying the symbols of grouped moving objects, setting the moving object symbols to be displayed with priority, displaying the wake indicator There is a setting of non-display and setting of its display direction, a grouping of moving objects existing in the controlled airspace, and a setting of starting / stopping a function for switching and displaying symbols of the grouped moving objects.

  FIG. 4 is a conceptual diagram illustrating an example of the display screen G. More specifically, FIG. 4 is a diagram illustrating an example of the display screen G including the setting image G2 for setting the above-described display specifications.

  As shown in FIG. 4, the display screen G is a screen that is displayed on the display unit 15 under the control of the control unit 10, and includes a monitoring image G <b> 1 and a setting image G <b> 2. The monitoring image G1 is an image that the monitoring information display unit 102 displays on the display unit 15 based on the display information of the monitoring information processing unit 101. A moving object (for example, P1 to P5) in the controlled airspace is vertically viewed from above. It is an image which projects on a horizontal surface and displays the state looked down from perpendicularly upward.

  In the monitoring image G1 illustrated in FIG. 4, moving objects are grouped for each rectangular reference area G10 divided by the vertical dividing line G11 and the horizontal dividing line G12, and the grouped moving object symbols are switched and displayed. The function is deactivated and all moving symbols are displayed. For this reason, for example, three moving object symbols P1 to P3 are displayed in the reference area G10i, and two moving object symbols P4 and P5 are displayed simultaneously in the reference area G10j, which makes it difficult to identify. Note that each moving object symbol such as the moving object symbols P1 to P5 is based on moving object information, a wake presence point S1 indicating the current position of the moving object, a symbol image S2 corresponding to the moving object, and a traveling direction image S3 indicating the moving direction of the moving object. It is the structure which has.

  The setting image G2 includes setting areas G21 to G27 for setting display parameters for grouping and displaying moving objects existing in the controlled airspace, and a button G28 for reflecting the setting. The setting area G21 is an area for setting a delimiter of the reference area G10 for grouping moving objects for each reference area G10 obtained by dividing the monitoring image G1 by the vertical dividing line G11 and the horizontal dividing line G12. Specifically, it is selected whether to set the actual distance in the vertical and horizontal directions of the reference area G10, the number of dots on the monitoring image G1, or the number of vertical and horizontal divisions in the monitoring image G1, and the input value is, for example, (vertical) × (horizontal) ) Value to set.

  The setting area G22 is an area for setting display / non-display of the vertical dividing line G11 and the horizontal dividing line G12. Specifically, the setting is made by selecting either a “display” button or a “non-display” button. The setting area G23 is an area for setting a range of areas in which moving objects are grouped and displayed. Specifically, by selecting either the “entire” button / “individual” button, the individual reference areas G10 of the entire monitoring image G1 are grouped, or the reference areas G10 are individually selected and selected. It is selected whether to group the reference area G10.

  Here, when the reference area G10 is individually selected (when the “individual” button is selected in the setting area G23), a touch operation of the reference area G10 desired to be grouped is received from the operator from the monitoring image G1. . For example, when the reference area G10i in which the three moving body symbols P1 to P3 are simultaneously displayed is grouped and the grouped moving body symbols P1 to P3 are to be switched and displayed, the operator selects the reference area G10i of the monitoring image G1. By touching, the reference area G10i can be made an area to be grouped.

  The setting area G24 is an area for setting a switching interval (cycle) when switching and displaying the grouped moving object symbols. Specifically, the value of the switching interval is input and set as the input value. The setting area G25 is an area for setting a moving object symbol to be displayed with priority. Specifically, a button corresponding to a moving object symbol to be displayed with priority is selected and set. The moving object symbol includes various shapes of moving object symbols for identifying the state of the moving object based on the moving object information. For example, there are a moving object symbol indicating an ally aircraft, a moving object symbol indicating an enemy aircraft, a moving object symbol indicating an enemy ally unknown aircraft (the same applies to ships and ground moving objects). The operator can select a moving object symbol to be displayed preferentially from these various shapes of moving object symbols.

  The setting area G26 is an area for setting display / non-display of the wake indicator and its display orientation. Here, the wake indicator is a sign indicating the number of grouped moving body symbols. When switching and displaying the grouped moving symbols for each reference area G10, the number of grouped moving symbols is used as a wake indicator in order to make it easy to understand how many moving symbols exist in the reference area G10. Display. Specifically, one of the “display” button / “non-display” button is selected, and in the case of display, the display orientation (display position of the wake indicator with respect to the moving object symbol) is input and set. As for the display azimuth, the display position of the wake indicator with respect to the moving object symbol may be designated as “upper left” or simply by the azimuth angle (for example, 315 °).

  The setting area G27 is an area for setting activation / stop of a function for switching and displaying the grouped moving object symbols. Specifically, it is set by selecting one of the “function activation” button and the “function stop” button.

  Returning to FIG. 3, after S11, the monitoring information processing unit 101 sets the moving object symbols indicating the moving objects existing in the controlled airspace according to the display parameters set in S11 based on the moving object information. A grouping process for grouping for each area G10 is performed (S12). Specifically, the position of each moving object included in the moving object information is referred to, and moving objects existing in the reference area G10 set to be grouped in the reference area G10 set as a delimiter are extracted and extracted. A group ID or the like is assigned to the moving object to be grouped.

  For example, if the reference areas G10i and G10j are grouped areas in the example of FIG. 4, the moving object symbols P1 to P3 existing in the reference area G10i are extracted and assigned the same group ID “i” and the like. . Further, the moving object symbols P4 and P5 existing in the reference area G10j are extracted, and the same group ID “j” or the like is assigned.

  Next, the monitoring information processing unit 101 selects a display symbol that is a moving object symbol to be displayed in each monitoring image G1 of the monitoring image G1 (S13). Here, for the reference area G10 to which no group ID is assigned, all moving body symbols are set as display symbols. In addition, for the grouped reference area G10 to which group IDs are assigned, display symbol selection is switched at predetermined time intervals among moving object symbols having the same group ID. For example, in the example of FIG. 4 described above, for the moving object symbols P1 to P3 in the reference area G10i to which the same group ID “i” or the like is assigned, the moving object symbols P1 → P2 → P3 → P1. Switching is performed at predetermined time intervals.

  Here, when the moving object symbol to be displayed with priority is set, the display symbol is selected so as to increase the display frequency of the moving object symbol to be displayed with priority. For example, when the moving object symbol P1 is preferentially displayed for the moving object symbols P1 to P3 in the reference area G10i to which the same group ID “i” or the like is assigned, the moving object symbol P1 → P2 → P1 → P3 → P1. As shown, the display frequency of the moving object symbol P1 is selected to be higher than that of the moving object symbols P2 and P3.

  Next, the monitoring information processing unit 101 calculates the center position of the symbol display for displaying the moving object symbol on the monitoring image G1 based on the moving object information (S14). Here, when the distance between the center position of the symbol display and the vertical dividing line G11 and the horizontal dividing line G12 is equal to or smaller than a predetermined value (distance from the center of the moving object symbol to the surroundings), the moving object symbol displayed on the monitoring image G1 A part of the area goes out of the reference area G10 across the vertical dividing line G11 and the horizontal dividing line G12. Therefore, when the distance between the center position of the symbol display and the vertical dividing line G11 and the horizontal dividing line G12 is equal to or less than the predetermined value, the center position of the symbol display is moved in the center direction of the reference area G10, so It correct | amends so that a part may straddle the vertical dividing line G11 and the horizontal dividing line G12, and it may not come out of the reference | standard area G10.

  Next, the monitoring information processing unit 101 calculates the display position of the track presence point S1 of each moving object on the monitoring image G1 based on the moving object information (S15). Next, the monitoring information processing unit 101 sets the number of moving objects to which the same group ID is assigned for the moving object symbols in the grouped reference area G10 having the group ID assigned according to the setting of the track indicator in the setting area G26. Display is set (S16). Next, the monitoring information processing unit 101 displays the moving object symbol in the monitoring image G1 based on the processing of S12 to S16 (S17).

  FIG. 5 is a conceptual diagram illustrating an example of the monitoring image G1, and more specifically, an example of the monitoring image G1 displayed in the process of S17 after the activation of the function of switching and displaying the grouped moving object symbols. FIG. As shown in FIG. 5, in the reference area G10 in which a plurality of moving objects are present, moving object symbols are grouped in S12, and display symbols are selected by switching one by one at a predetermined time interval in S13. Since the displayed display symbols are displayed, even if many moving objects are densely arranged in one area, the moving object symbols do not overlap and become difficult to see.

  FIG. 6 is a conceptual diagram illustrating switching of moving object symbols P1 to P3. As shown in FIG. 6, in the reference area G10i where a plurality of moving objects are present, the moving object symbols P1 to P3 are switched and displayed at predetermined time intervals.

  FIG. 7 is a conceptual diagram illustrating switching when a moving object symbol to be displayed with priority is set. As shown in FIG. 7, when the moving object symbol P10 is displayed with priority among the moving object symbols P10 to P13, the moving object symbol P10 → P11 → P10 → P12 → P10 → P13 → P10 → P11... It is selected so that the display frequency of the moving object symbol P10 is increased during the entire display. Therefore, it becomes easier for the operator to identify the moving object symbol P10 having a high priority.

  FIG. 8 is a conceptual diagram illustrating movement of a moving object symbol. As shown in FIG. 8, when the symbol display center position is close to the edge of the reference area G10 and the symbol image S2 is displayed as it is, a part of the symbol display moves outside the reference area G10. The symbol image S2a and the traveling direction image S3a are displayed. Thereby, it is possible to prevent overlapping with the vertical dividing line G11 and the horizontal dividing line G12 that divide the reference area G10, and to prevent part of the reference area G10 from overlapping with other moving body symbols.

  FIG. 9 is a conceptual diagram illustrating a wake indicator S4 indicating the number of grouped moving object symbols P. As shown in FIG. 9, in the grouped moving body symbol P, the number of grouped moving body symbols is displayed on the wake indicator S4 according to the setting of the wake indicator. Therefore, the operator can recognize the number of moving objects grouped in the reference area G10 by checking the wake indicator S4.
