Description

  The present invention relates to a radar information processing apparatus and a radar information processing program for displaying radar information on an aircraft or the like and operation data corresponding to an input operation by a controller or the like on a radar screen.

  In general, in air traffic control, information on the position and model of an aircraft obtained from a radar device is displayed on a radar screen. The controller performs control work using information displayed on the radar screen. The controller can operate each information displayed on the radar screen by using various input devices such as a keyboard, a pointing device, and buttons.

  2. Description of the Related Art Conventionally, an air traffic control interface device that can store and store image information and communication audio content of a display device and easily monitor the state of an aircraft in air traffic control has been considered (see, for example, Patent Document 1).

  In the apparatus described in Patent Literature 1, the display processing unit receives information obtained by collating information on the aircraft transmitted from the flight plan information processing system with information on the current position transmitted from the airway radar information processing system. A symbol indicating the position of the aircraft is displayed based on the position information of the aircraft. When the controller wants to save the displayed image, he / she operates the input unit to instruct the display processing unit. Receiving this instruction, the display processing unit stores the information related to the aircraft corresponding to the image being displayed, the information related to the current position, and the storage time in the information storage unit. The display processing device adjusts the scale and display range of the image based on the stored information according to the size of the display area of the stored information display unit, and causes the stored information display unit to display the image.

  In Patent Document 1, information related to the aircraft, information related to the current position, and the storage time are stored, but it is further required to record the input operation by the controller.

  FIG. 6 is a block diagram illustrating a configuration of a radar information processing apparatus for recording data including input operation data by a controller or the like in addition to information regarding an aircraft and information regarding a current position.

  The radar information input unit 10 inputs radar information (aircraft position, identification code, altitude, etc.) detected by a radar device (not shown), sends it to the radar information processing unit 12, and indicates the time when the radar information is input. Data is added and stored in the radar information storage unit 11 in time series.

  Based on the radar information input from the radar information input unit 10, the radar information processing unit 12 processes the flight plan and model information of the aircraft captured by the radar to create flight plan information, and the operation data record storage unit 13. To record.

  The operation / display processing unit 140 generates drawing data for displaying a radar screen based on the radar information input by the radar information input unit 10 and the flight plan information created by the radar information processing unit 12. The operation / display processing unit 140 controls the display control unit 180 by outputting a drawing command for displaying a radar screen corresponding to the drawing data to the display control unit 180, and causes the display unit 22 to display the radar screen. For example, information such as an aircraft symbol, a flight number, and an altitude is displayed on the radar screen.

  Further, the operation / display processing unit 140, when there is an input operation to the operation unit 17 by a controller or the like, for example, an input operation for selecting a symbol representing an aircraft displayed on the radar screen, the operation input by this operation The data is recorded in the operation record storage unit 15 with the addition of data indicating the operated time. For example, position data designated using a pointing device on the radar screen is recorded.

When the reproduction output of the information recorded from the operation unit 17 is requested, the operation / display processing unit 140 stores the radar information stored in the radar information storage unit 11 through the radar information input unit 10 and the operation record storage unit 15. Read stored operation data in time series. Then, drawing data is created in synchronization with the radar information and the time data added to the operation data, and is displayed on the display unit 22. As a result, a radar screen including a display corresponding to the operation data can be reproduced and output.

  As described above, conventionally, the radar information acquired by the radar device and the operation data input in response to the input operation are respectively recorded by adding data indicating the time, and the time is set when reproducing and outputting. The radar screen was displayed in synchronization with the data shown.

  However, in the conventional radar information processing apparatus, there is a possibility that a slight timing shift may occur between the radar information displayed on the radar screen and the data display according to the input operation of the controller. For example, time information input by the radar information input unit 10 is added to the radar information, but the operation data is input by an input operation performed on the radar information displayed on the radar screen. Therefore, depending on the load status of the device, if it takes time until the radar information is input and displayed, a difference occurs between the time when the radar information is input and the time when the input operation is performed. If synchronization is made based on the time, there will be a difference between the display of radar information and the display of operation data corresponding to the input operation. For example, when there is an input operation for selecting a symbol displayed on the radar screen, a display as if the input operation was performed at a position deviated from the position where the symbol was displayed is performed.

  For this reason, conventionally, for example, by taking a radar screen using a VTR or a photograph, the radar screen on which the display corresponding to the radar information and the data input in the input operation are displayed is directly recorded. It was broken. In this case, there arises a problem that the normal control operation is hindered and long-time recording becomes difficult.

  An object of the present invention is to provide a radar information processing apparatus and a radar information processing program capable of recording and reproducing a radar screen in which the display of radar information and the display of operation data coincide with each other without hindering control operations. It is in.

  The present invention provides a radar information processing apparatus for displaying radar information relating to an aircraft or the like and operation data corresponding to an input operation by a controller or the like on a radar screen, for displaying the radar information corresponding to the radar information and the operation data. Drawing data creation means for creating drawing data, drawing command output means for outputting a drawing command for executing display of drawing data created by the drawing data creation means, and drawing output by the drawing command output means It is characterized by comprising drawing command recording means for recording commands in time series and drawing command reproduction means for reproducing and displaying a radar screen according to the drawing commands recorded by the drawing command recording means.

  According to the present invention, the drawing commands output for displaying the radar screen corresponding to the radar information and the operation data are recorded in time series, and when the radar screen is reproduced and output, the recorded drawing commands are recorded. By reading and displaying in time series, it is possible to record and reproduce the radar screen in which the display of radar information and the display of operation data coincide. Since the drawing command is recorded while the radar screen is displayed during the normal control operation, the control operation is not hindered.

Next, the operation of the radar information processing apparatus in the present embodiment will be described with reference to FIGS.
FIG. 2 is a flowchart for explaining radar information processing in the present embodiment. FIG. 3 is a diagram showing a flow of processing in radar information processing.

  Radar information relating to an aircraft or the like detected by a radar device (not shown), for example, information relating to the position and altitude of the aircraft, a model (identification command, etc.), etc. is input by the radar information input unit 10. The radar information input unit 10 sends the input radar information to the radar information processing unit 12, adds data indicating the time when the radar information is input, and stores the data in the radar information storage unit 11 in time series (step). A1).

  Next, based on the radar information input from the radar information input unit 10, the radar information processing unit 12 processes the flight plan and model information of the aircraft captured by the radar, creates flight plan information, and records operation data. Record in the storage unit 13 (step A2).

  The operation / display processing unit 14 (the drawing data creation unit 16 displays the radar screen based on the radar information input by the radar information input unit 10 and the flight plan information created by the radar information processing unit 12. (Step A5) The operation / display processing unit 14 outputs a drawing command for displaying a radar screen corresponding to the drawing data created by the drawing data creation unit 16 to the display control unit 180. (Step A6).

  At this time, the drawing command recording unit 20 of the display control unit 18 records the drawing commands output from the operation / display processing unit 14 in the drawing command storage unit 19 in time series (step A7). Further, the display control unit 18 displays the display object on the display unit 22 in accordance with the drawing command from the operation / display processing unit 14 (step A8). On the radar screen, for example, information such as an aircraft symbol, a flight number, and an altitude is displayed. By repeatedly executing the above processing, the radar screen corresponding to the input radar information can be continuously displayed.

  Here, it is assumed that the controller performs an input operation on the operation unit 17 in order to execute some processing on the information displayed on the radar screen. When the operation data is input by the input operation to the operation unit 17 (Yes in Step A3), the operation / display processing unit 14 adds the data indicating the operation time to the input operation data and accumulates the operation record. It records in the part 15 (step A4).

  In this case, the drawing data creation unit 16 creates drawing data including a display object corresponding to the operation data.

  For example, when an input operation for selecting a symbol representing an aircraft displayed on the radar screen is performed on the pointing device, the display position is changed according to the operation of the pointing device, or the cursor is selected by the cursor. A symbol whose display form has changed is displayed on the screen.

  The operation / display processing unit 14 outputs a drawing command for displaying drawing data including a display object corresponding to the operation data to the display control unit 18. By repeatedly executing this, for example, a radar screen or the like representing the movement of the cursor display position described above can be displayed.

When the reproduction output of the radar screen is requested through the operation unit 17, the operation / display processing unit 14 outputs a reproduction command to the display control unit 18 (step B1).

  In response to the playback command from the operation / display processing unit 14, the display control unit 18 starts reproduction output of the radar screen using the drawing command recorded in the drawing command storage unit 19.

  That is, the drawing command playback unit 21 of the display control unit 18 reads the drawing commands recorded in the time series in the drawing command storage unit 19 in time series (step B2), and displays a display object corresponding to the drawing command in the display unit. 22 is displayed (step B3). This is repeated until all drawing commands to be reproduced and output are read (steps B2 to B4).

  The drawing command recorded in the drawing command storage unit 19 is a recording of the drawing command output from the operation / display processing unit 14 in order to actually display the radar screen. By reading sequentially and displaying the display object on the display unit 22, it is possible to display a radar screen that is exactly the same as the radar screen actually displayed during radar information processing. That is, there is no deviation in the display timing of the radar information displayed on the radar screen and the display object displayed in accordance with the input operation.

  In the above description, in the radar information processing executed during the control operation, the drawing command is described as being recorded in the drawing command storage unit 19 in time series. ) Recording start / end may be instructed. In this case, when a recording start instruction is input from the operation unit 17, the operation / display processing unit 14 outputs a recording start command to the display control unit 18 (the drawing command recording unit 20). The drawing command recording unit 20 records the drawing commands output from the operation / display processing unit 14 in time series in accordance with the recording start command as described above. When a recording end instruction is input from the operation unit 17, a recording end command is output to the display control unit 18 (drawing command reproduction unit 21). The drawing command playback unit 21 ends the recording of the drawing command in response to the recording end command. At this time, it is assumed that arbitrary identification information (recording date and time, title arbitrarily input from the operation unit 17) is added to the recorded drawing command group of the radar screen.

  In the radar information reproduction process, when the radar screen is reproduced and output using the drawing command recorded in the drawing command storage unit 19, the identification information added at the time of recording is designated and reproduced and output individually. Can do.

  In the above description, the radar screen that displays the radar information input from the radar information input unit 10 and the operation data input from the operation unit 17 is described as being recorded and reproduced. The flight plan information recorded in the unit 13 may be displayed on the radar screen. In this case, since the drawing command for displaying the radar screen including the flight plan information is output from the operation / display processing unit 14, the drawing command is recorded in time series and reproduced and output in the same manner as described above. It ’s fine.
