  FIG. 2 is a block diagram schematically showing a functional configuration of the aircraft information display device 1. As shown in FIG. 2, the monitoring screen processing unit 101 uses the inputted aircraft information and the building / terrain information read from the building / terrain information file 172 to determine the aircraft, building / terrain in the controlled airspace. Is generated as a monitoring screen on the display unit 15. Specifically, the monitoring screen processing unit 101 generates display information for displaying a two-dimensional monitoring screen that two-dimensionally displays an aircraft, a building, and a landform in the controlled airspace on a horizontal plane looking down from above. Further, based on the operation data output from the monitoring screen operation unit 103, display information for generating a projection screen obtained by projecting an area (region) set on the two-dimensional monitoring screen onto a vertical plane is generated.

The aircraft / information and the building / terrain information file 172 stored in the storage unit 17 are acquired (S1). Next, the monitoring screen processing unit 101 refers to the aircraft position (longitude, latitude) included in the aircraft information and the position of the building or terrain (latitude, longitude) included in the building / terrain information, so that the Display information of a two-dimensional monitoring screen in which an aircraft, a building, or a terrain is looked down vertically is generated, and the generated display information is output to the monitoring screen display unit 102 to display the two-dimensional monitoring screen on the display unit 15 (S2). ). This two-dimensional monitoring screen is a two-dimensional map obtained by projecting aircraft, buildings, and terrain in the controlled airspace onto the horizontal plane from vertically above.

  FIG. 4 is a conceptual diagram showing an example of the two-dimensional monitoring screen G1. As shown in FIG. 4, the two-dimensional monitoring screen G1 displays two-dimensionally the aircrafts A1 to A18 flying in the controlled airspace based on the aircraft position included in the aircraft information. On the two-dimensional monitoring screen G1, terrain M1 and M2 such as hills and mountains in the controlled airspace, and the building M3 are also aircraft based on the position of the building and terrain included in the building / terrain information. Two-dimensionally displayed together with A1 to A18.

  Next, the monitoring screen operation unit 103 receives an operator's operation on the two-dimensional monitoring screen G1 from the operation unit 14, and receives selection of the aircrafts A1 to A18 as points of interest on the two-dimensional monitoring screen G1 (S17). The selection of the aircrafts A1 to A18 as the attention points on the two-dimensional monitoring screen G1 may be performed by a touch operation on the two-dimensional monitoring screen G1 or an operation such as a cursor key. In this embodiment, the case where the aircrafts A1 to A18 are selected as the attention points on the two-dimensional monitoring screen G1 is illustrated, but the attention points on the two-dimensional monitoring screen G1 may be other than the aircrafts A1 to A18. . For example, the point of interest on the two-dimensional monitoring screen G1 may be a terrain such as M1, M2, M3, or a building, or a predetermined airspace. In this case, the operator touches and sets the desired point of interest. To do. In the example of FIG. 4, the aircraft A10 is selected, and a projection direction setting cursor P3 indicating that it has been selected is displayed on the selected aircraft A10.

  Next, the monitoring screen operation unit 103 receives the operator's operation from the operation unit 14, and receives selection of the type of area (region) including the aircraft A10 set as the point of interest, that is, the shape of the outer edge surrounding the area (S4). ). The types of areas accepted here include “circle”, “rectangle”, “polygon”, and “fan shape”. In S <b> 4, the monitoring screen processing unit 101 outputs display information for displaying a selection screen for selecting the “circle”, “rectangle”, “polygon”, and “fan shape” to the monitoring screen display unit 102, and displays it on the display unit 15. Display the selection screen. The monitoring screen operation unit 103 receives an operator's selection operation on the selection screen from the operation unit 14, and outputs the received operation data to the monitoring screen processing unit 101.

  The monitoring screen processing unit 101 determines the type of area received in S4 (S5). When the area type is “circle”, the monitoring screen operation unit 103 receives the radius of the circle centered on the aircraft A10 set as the point of interest from the operator, and sets the radius of the circle (S6). Specifically, a screen for setting the radius of the circle is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. The method for setting the radius of the circle by this input operation is to enter the numerical value of the distance (circle radius) using the keyboard or specify (click) a desired point on the two-dimensional monitoring screen G1, and set the aircraft A10 set as the point of interest. The distance between and may be the radius of the circle.

  When the area type is “rectangular”, the monitoring screen operation unit 103 receives and sets the side length of the rectangle including the aircraft A10 set as the point of interest from the operator (S7). Specifically, a screen for setting the latitude and longitude of the start point of the rectangle and the vertical and horizontal distances is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. The rectangular setting method by this input operation is a method of inputting numerical values in the vertical and horizontal directions using the keyboard or designating (clicking) desired two points on the two-dimensional monitoring screen G1 as start points and end points. A rectangle may be used.

  When the area type is “polygon”, the monitoring screen operation unit 103 accepts and sets the vertex of the polygon including the aircraft A10 set as the point of interest from the operator (S8). Specifically, a screen for setting a vertex of the polygon is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. The polygon setting method by this input operation is to input the latitude / longitude as the vertex of the polygon or specify (click) a desired point on the two-dimensional monitoring screen G1, and use the specified point as the vertex. It may be a polygon.

  When the type of area is “fan shape”, the monitoring screen operation unit 103 receives and sets the radius and center angle of the fan shape centered on the aircraft A10 set as the point of interest from the operator (S9). Specifically, a screen for setting a sector radius, a start angle, and an end angle is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. The sector setting method by this input operation is to input numerical values of the radius and center angle of the sector or to specify (click) two desired points on the two-dimensional monitoring screen G1, and to specify the two specified points in the shape of a sector arc. It may be a start point (setting of the start angle and sector radius) and an end point (setting of the end angle).

  Subsequent to S7, S8, and S9, the monitoring screen operation unit 103 receives and sets the rotation angle of the area from the operator with reference to the aircraft A10 set as the point of interest (S10). Specifically, a screen for setting the rotation angle of the area is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. The method of setting the rotation angle by this input operation is to input a numerical value of the rotation angle or specify (click) a point on the two-dimensional monitoring screen G1, and connect the aircraft A10 set as the point of interest with the specified point. The angle between the line and a line extending directly below the aircraft A10 may be the rotation angle.

  By the above S6 to S10, the outer edge of the area including the aircraft A10 set as the point of interest is set. In the example of FIG. 4, when the area type is a circle, an area setting frame P <b> 2 is set as the outer edge of the circle including the aircraft A <b> 10 set as the point of interest by setting the radius. In the example of FIG. 6 to be described later, when the area type is a sector shape, the area is set as a fan-shaped outer edge centered on the aircraft A10 set as the point of interest by setting the radius and the central angle. A frame P2 is set.

  Subsequent to S6 and S10, the monitoring screen operation unit 103 receives and sets the projection direction for projecting the set area from the operator (S11). Specifically, a screen for setting the projection direction for projecting the area is displayed on the display unit 15, and an operator's input operation is received from the monitoring screen operation unit 103. A method for setting the projection direction by this input operation is as follows: the numerical value of the angle of the projection direction with respect to the area, the point on the two-dimensional monitoring screen G1 is designated (clicked), and the aircraft A10 set as the point of interest is set. The direction connecting the points may be the projection direction. In the example of FIG. 4, the projection direction setting cursor P3 is displayed at the position where the point on the two-dimensional monitoring screen G1 is designated (clicked), and the projection direction is set so as to project the area including the aircraft A10 from the front side. ing.

  Next, the monitoring screen operation unit 103 accepts selection of whether or not to display the display items related to the aircraft in the area (distance to the aircraft A10 set as the point of interest, position (altitude) error, speed, etc.) from the operator. (S12). Specifically, a screen (for example, a selection screen using a check box) for selecting whether or not to display is displayed on the display unit 15 for each display item such as distance, position error, and speed, and the monitoring screen operation unit 103 Accepts operator input.

  Next, the monitoring screen processing unit 101 searches for aircraft information regarding buildings, terrain, and building / terrain information included in the areas set in S4 to S10 (S13). Specifically, the outer edge of the area set on the two-dimensional monitoring screen G1 is converted into latitude / longitude, and aircraft information and building / terrain information within the converted latitude / longitude are searched.

  Next, the monitoring screen processing unit 101 refers to the aircraft information and building / terrain information retrieved in S13, and generates a projection map in which the area set in S4 to S10 is projected in the projection direction set in S11 (S14). . Specifically, the monitoring screen processing unit 101 replaces the aircraft, the building, and the terrain in the area with the three-dimensional coordinates from the aircraft information and the building / terrain information in the area obtained by the search. Next, the monitoring screen processing unit 101 places the virtual light source on the front side of the area in the projection direction, and replaces the aircraft, the building, and the terrain replaced with the three-dimensional coordinates on the vertical plane orthogonal to the projection direction on the opposite side of the projection direction area. A projected view is obtained. Note that the projection here allows transmission (perspective). Specifically, even if there is an aircraft, building, or terrain on the near side in the projection direction, the aircraft, building, or terrain on the far side in the projection direction is not hidden and displayed in the projected view. Good thing.

  Further, the virtual light source may be placed at the position set as the projection direction setting cursor P3 in FIG. 4, but in this embodiment, the virtual light source is placed at infinity. In this way, by setting the virtual light source for projection at infinity, parallel light is projected to the set area, so the height relationship between the aircraft, buildings, and terrain in the area remains unchanged. Can be projected (in parallel).

  Next, the monitoring screen processing unit 101 displays the projection diagram created in S14 on the display unit 15 as a projection screen (S15). Specifically, the monitoring screen processing unit 101 generates display information for displaying the projection map created in S <b> 14 on the projection screen and outputs the display information to the monitoring screen display unit 102. The monitoring screen display unit 102 displays a projection screen on the display unit 15 based on the display information output from the monitoring screen processing unit 101. At this time, the monitoring screen display unit 102 reads the display specifications set for display in S12 for the aircraft projected on the projection screen from the aircraft information, and displays it at a position corresponding to the projected aircraft.

  5 and 6 are conceptual diagrams illustrating an example of the projection screen G2. More specifically, FIG. 5 is a conceptual diagram of the projection screen G2 when a circle is set as the area type, and FIG. 6 is a concept of the projection screen G2 when a sector is set as the area type. FIG. As shown in FIG. 5, in S <b> 15, a projection screen G <b> 2 in which the area setting frame P <b> 2 is projected on the vertical plane when a circle is set as the area type is displayed on the display unit 15. Therefore, by checking the projection screen G2, the operator can intuitively and quickly determine the accurate altitude relationship among the aircrafts A6, A7, A8, A10, A11, A12, the terrain M2, and the building M3 included in the area setting frame P2. I can grasp it. Similarly, when a sector is set as the type of area, as shown in FIG. 6, a projection screen G <b> 2 in which the inside of the sector-shaped area setting frame P <b> 2 is projected on the vertical plane is displayed on the display unit 15. Thus, the operator can intuitively and quickly grasp the altitude relationship between the aircrafts A8, A10, and A11 included in the sector-shaped area setting frame P2. Thus, by changing the type of area, the operator can confirm the altitude relationship between the aircraft, the building, and the terrain in the area of the desired shape.

  Further, as shown in FIG. 5, distance information D indicating the distance to the aircraft A10 set as the point of interest as the display specifications of the aircraft A6, A7, A8, A10, A11, A12 set in S12, the altitude Since the error information H and the speed information V are displayed, the states of the aircrafts A6, A7, A8, A10, A11, and A12 in the area can be grasped in detail. In addition, about the distance information D which shows the distance with respect to aircraft A10 set as an attention point, you may change a display mode according to the positional relationship (front side or back side) in a projection direction. Specifically, for the distance information D of the aircrafts A8 and A11 on the near side in the projection direction with respect to the aircraft A10, the distance value is enclosed by a regular triangle, and the aircraft A6 is located in the projection direction with respect to the aircraft A10. , A7, and A12, the display mode may be changed such as enclosing the numerical value of the distance with an inverted triangle.

  Next, the monitoring screen processing unit 101 determines whether or not aircraft information input from the control information processing system has been updated (S16). Specifically, the monitoring screen processing unit 101 temporarily stores aircraft information input from the control information processing system in a RAM or the like, and then temporarily stores the aircraft information input from the control information processing system. The presence or absence of the update is determined by comparing with the aircraft information. When the aircraft information is updated (S16: YES), the monitoring screen processing unit 101 returns the process to S13 to update the projection screen G2 based on the updated aircraft information.

  When the aircraft information is not updated (S16: NO), the monitoring screen operation unit 103 determines an operation input from the operator (S17). If the operation input from the operator is “none”, the process returns to S15 in order to continue displaying the projection screen G2. If the operation input from the operator is “aircraft” for starting the selection of the aircraft as the attention point, the process returns to S3 to return to the selection of the aircraft as the attention point. When the operation input from the operator is “area type” for starting selection of the area type, the process returns to S4 to return to the selection of the area type. If the operation input from the operator is “projection direction” for starting the setting of the projection direction, the process returns to S11 to return to the setting of the projection direction. Further, when the operation input from the operator is “display specifications” for starting the setting of display specifications, the process returns to S12 in order to return to the selection setting of display specifications. If the operation input from the operator is “end” for ending the display of the monitoring screen, the process is ended.
