Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an aircraft position display device, and more particularly to display control capable of immediately confirming a distance relationship between a designated position and an aircraft or between aircrafts .
[0002]
[Prior art]
In an aircraft monitoring system installed in a control tower or the like, a flight position of an aircraft is detected by scanning a radar at predetermined time intervals, and the detected position is displayed on a display board. The controller constantly monitors the flight position of each aircraft on the display board to ensure that a sufficient distance between the aircraft is secured. In order to avoid a collision, it is necessary to secure a certain distance or more, but when it is difficult to visually determine the distance, conventionally, the distance between aircrafts can be measured by the following method. did it.
[0003]
That is, the controller picks up the mouse by moving the mouse cursor to each of the two target machines on the display board whose distance is to be measured, and performs a measurement request operation. In response to this request, the system calculates the distance between picked aircraft and displays it on the screen.
[0004]
[Problems to be solved by the invention]
However, in the conventional method, two aircrafts whose distances are to be measured have to be picked from the display board. In other words, when there are multiple aircraft whose distances are to be measured with respect to one aircraft, it is troublesome because each aircraft must be picked at two points manually and a measurement request operation must be performed. . In addition, it was troublesome to read the displayed distance one by one to determine whether the necessary distance was maintained.
[0005]
By the way, conventionally, in addition to the above-described conventional example, the following system also exists. For example, a condition that the aircraft has entered the airspace under the jurisdiction is set as a condition, and for each aircraft that matches the condition, a circle with the center of the aircraft and a predetermined radius is automatically displayed. Move the circle following the aircraft. In this conventional example, the distance relationship between the aircraft and other aircraft can be clearly understood by always displaying a circle. However, in this conventional example, the distance between aircrafts cannot be confirmed unless the set conditions are met. Also, because the circles are forcibly displayed while the conditions are met, for example, in the vicinity of the airport, the circles overlap and become complicated, and even if the display status is seen, On the other hand, it becomes difficult to understand which aircraft should be paid attention to.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0017]
Embodiment 1 FIG.
FIG. 1 is an overall configuration diagram showing Embodiment 1 of an aircraft monitoring system according to the present invention. This aircraft monitoring system is a system generally used in air traffic control. FIG. 1 shows a tracking processing device 1 that performs tracking based on the flight position of an aircraft detected by a radar device (not shown), a map on a display 2 for monitoring the flight status of the aircraft, and the flight of each aircraft on the map. A display device 3 for displaying the position is shown. The aircraft monitoring system includes devices such as an alarm processing device in addition to the radar device described above, but is omitted from the drawing because it is not a feature of the present embodiment. In addition, although the devices 1 and 3 shown in the drawings have conventionally existed, the components that perform the conventional processing functions are not shown.
[0018]
The tracking processing device 1 includes a position information generation processing unit 4 that generates flight position information including the flight name and flight position of each aircraft obtained as a result of the tracking process. Since the position information generation processing unit 4 is conventionally provided in the tracking processing device 1 to display the flight position of the aircraft on the display device 3, the existing information is used without being provided separately in this embodiment. .
[0019]
The display device 3 displays the flight position of each aircraft on the display 2 based on the flight position information of each aircraft sent from the tracking processing device 1. When scanning is performed by the radar rotating once at a predetermined time interval, for example, every 4 seconds, the flight position of each aircraft is updated every 4 seconds, so the display device 3 also displays the display position of each aircraft. It will be updated every 4 seconds. The display device 3 is provided with a graphic display processing unit 5 and has a function as an X server in charge of screen display and input of a mouse 6 as a pointing device. The display device 3 according to the present embodiment also has a function of a client that uses the X server function. FIG. 1 shows a map display control unit 7, an aircraft display control unit 8 and a cursor corresponding to this function. A display control unit 9 is shown.
[0020]
The map display control unit 7 performs map display control based on a map database (not shown). The aircraft display control unit 8 performs display control of the flight position of each aircraft in consideration of the scale of the map displayed based on the flight position information sent thereto. The cursor display control unit 9 controls the display of the mouse cursor on the screen. In the present embodiment, the cursor display control unit 9 is provided with a circle display control unit 10 that displays the cursor in a circle according to the mouse operation. It is said.
[0021]
Next, the operation of the aircraft monitoring system in the present embodiment will be described using the display examples shown in FIGS. In addition, from each figure, the display of the flight number etc. which identify each aircraft is abbreviate | omitted.
[0022]
First, FIG. 2 shows three aircrafts 11, 12, and 13 that have entered the surveillance area in order to land at the airport 11. In this display screen, the aircraft display control unit 8 displays the flight positions of the aircrafts 11 to 13 on the map displayed by the map display control unit 7 at a predetermined scale. Based on this display content, the controller confirms visually whether or not a safe distance is regularly maintained between the aircrafts 11 to 13 in order to ensure safety. However, when it is difficult to visually determine the distance, the controller operates the mouse 6 and moves the mouse cursor 15 to one aircraft on which the distance between flight positions is to be measured on the display 2 as shown in FIG. For example, a predetermined mouse operation such as a left click is performed. When the graphic display processing unit 5 receives an input from the controller, the graphic display processing unit 5 notifies the cursor display control unit 9 to that effect. The circle display control unit 10 of the cursor display control unit 9 displays a circle having a predetermined radius with the current position of the aircraft 12 selected by the mouse operation in response to the notification as a center. In the case of the present embodiment, the predetermined radius indicates a predetermined safety distance based on the current map scale. In order to show a fixed distance, a display radius changes with map scales. In the present embodiment, the arrow-shaped mouse cursor is changed to a circular shape and displayed. An example of this display is shown in FIG.
[0023]
As described above, when a safe distance, for example, a circle of 3 miles, is displayed on the display 2 on the screen of the aircraft 11, it is obvious whether the distance of 3 miles from the aircraft 11 is maintained. be able to. Further, in the present embodiment, it is only necessary to perform a mouse operation on only one aircraft 11, and the operation is also simple. In this embodiment, since the distance relationship is displayed as a circle, not only the relationship between the aircraft 11 and the aircraft to be measured but also the distance between the aircraft 11 and a plurality of aircraft. The relationship can be confirmed at the same time. In addition, since the circle can be displayed only for the aircraft selected manually by the controller, there is no possibility that it will be difficult to see by displaying many circles on the screen.
[0024]
According to the present embodiment, as described above, the mouse cursor is displayed in a circular shape in accordance with a predetermined operation, so that the distance between the aircraft can be confirmed by an extremely simple operation. Thereafter, the shape of the mouse cursor can be returned to an arrow by performing a predetermined operation such as a left click.
[0025]
As in this embodiment, since the purpose of confirming the distance between the aircraft is clear, when the object type to which the mouse cursor is to be set is determined to be an aircraft, the display position of the mouse cursor is set to each aircraft. When the mouse cursor position matches the display position of any aircraft, the shape of the mouse cursor may be automatically switched to a circle without accepting any mouse operation. Since the position of the mouse cursor on the screen is always detected by the graphic display processing unit 5, the comparison can be performed in real time. When a circular cursor is displayed simply by aligning the cursor position, it can be restored to the original arrow-shaped cursor by simply shifting the center of the circle from the aircraft. As a result, the distance relationship with other aircraft can be confirmed at a glance with only a very simple operation of setting the cursor to the target object.
[0026]
Embodiment 2. FIG.
In the first embodiment, the cursor display control unit 9 is provided with the circle display control unit 10 so that the shape of the mouse cursor is changed from a general arrow to a circle. In the present embodiment, the circle display control unit 10 is configured separately from the cursor display control unit 9, and a circle is displayed separately from the mouse cursor when the mouse cursor is selected according to the flight position of the aircraft.
[0027]
Embodiment 3 FIG.
In the second embodiment, a circle is displayed centered on the aircraft selected with the mouse cursor. The present embodiment is characterized in that the circle displayed following the movement of the selected aircraft on the display 2 is moved.
[0028]
That is, also in the present embodiment, a circle with a predetermined radius centered on the aircraft 12 is displayed on the display 2 in accordance with a predetermined operation, as in the second embodiment. The circle is made independent of the mouse cursor in response to a mouse operation or a separate input instruction, and the circle is moved following the movement of the aircraft 12. That is, it can be said that the center of the circle has been transferred from the cursor to the display position of the aircraft 12. Since the display position of each aircraft on the screen can be grasped, the following display of the circle can be easily performed. An example of this screen display is shown in FIG. 5, and it can be seen that the aircraft 12 has approached the airport 11 over time. Also at this time, it can be seen that the circle assigned to the aircraft 12 moves following the movement of the aircraft 12.
[0029]
Also, when the scale of the map is changed in a state where the circle can be displayed for a relatively long time according to the flight status of the aircraft as in this embodiment, the radius on the display screen is changed according to the changed scale. It is necessary to switch the size.
[0030]
By the way, the fact that a circle can be displayed independently of the mouse cursor means that a plurality of circles may be displayed simultaneously on the screen. If displayed, it will become complicated on the screen. Therefore, the circle display control unit in the present embodiment has a circle display / non-display switching function, and displays a circle displayed corresponding to the corresponding aircraft according to a predetermined operation by the controller. / Controls non-display.
[0031]
Embodiment 4 FIG.
FIG. 6 shows an example of screen display in the present embodiment. The present embodiment is characterized in that the circles are concentric circles. Thereby, not only the presence / absence of the safety distance but also the distance relationship with the aircraft from the center position can be clearly understood. In other words, in the case of each of the above embodiments, the radius of the circle is set for the purpose of separating the safe / dangerous distance in order to avoid a collision between aircrafts. Separately or in addition to confirming the safety distance, the radius of each circle can be set according to the purpose, such as setting the radius of each circle at equal intervals in order to grasp the distance relationship. In the above description, the object to be selected by aligning the mouse cursor to confirm the distance relationship with the aircraft has been described as an example of an aircraft that is a moving body. For example, concentric circles are displayed in accordance with the control district control station. By doing so, the distance relationship between the control station and each aircraft can be grasped at a glance. The control station is not a moving body and is a position that does not move, but according to the present embodiment, such a usage is also possible. When the cursor is fixed to the control station, the concentric circles may be automatically displayed when the cursor position matches the display position of the control station as described in the first embodiment.
[0032]
As described above, according to each of the above-described embodiments, the circle centered on one point indicated by the controller is displayed. Therefore, the two devices to be measured are not indicated by the cursor of the pointing device. Even the distance relationship between the two aircraft can be confirmed. Also, the distance relationship is indicated by a circle, so it is obvious. In addition, since the circle is displayed only for the object designated by the controller, the screen is not complicated.
[0033]
In each of the above embodiments, a circle centered on the cursor position is displayed on the display 2 so that the distance relationship between the position pointed by the mouse cursor and the aircraft can be clearly understood. However, depending on the position pointed on the display 2, the window size, the size and shape of the monitoring area, the set radius (distance), and the scale of the map, there is a possibility that the image is displayed in an arc instead of a circle. Alternatively, only a part of the circle may be displayed by display control by the circle display control unit. The present invention includes a case where such a circular shape is displayed in an incomplete state.
[0034]
In the present embodiment, the mouse 6 is exemplified as the pointing device, but other devices such as a pen and a trackball may be used.
[0035]
Further, in each of the above-described embodiments, the case where the mobile object position display device according to the present invention is applied to an aircraft monitoring system has been described as an example. However, the present invention is also applicable to a system that displays a ship, a vehicle, a bird, etc. can do.
[0036]
【The invention's effect】
According to the present invention, the distance between the position where the cursor is positioned and the aircraft can be easily grasped simply by performing a very simple predetermined operation of adjusting the cursor position by operating the pointing device.
[0037]
Moreover, since so as to follow the movement of the circle to the mobile, it can be confirmed at all times even if the distance relationship between the aircraft and other aircraft as the aircraft moves.
[0038]
In addition, since the display / non-display of the circle can be switched, it is possible to prevent the displayed circle from being complicated by the displayed circle.
[0039]
In addition, since the circles are concentric circles, the distance relationship from the center can be clearly understood.
[0040]
In addition, since the radius of the circle to be displayed is adjusted according to the scale of the figure, the correct distance relationship can be grasped even when the scale of the map is changed.
