BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving body position display device, and more particularly to display control capable of immediately confirming a designated position and a moving body or a distance relationship between moving bodies.

[0002]

2. Description of the Related Art In an aircraft surveillance 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 see if the distance between the aircraft is sufficiently secured. In order to avoid collision, it is necessary to secure a certain distance or more, but when the distance is difficult to judge visually, conventionally, the following method has been used to measure the distance between aircraft. did it.

That is, the controller performs picking operation by placing the mouse cursor on each of the two target machines on the display board whose distance is desired to be measured, and performs the measurement request operation. The system calculates and displays the distance between the picked aircraft in response to this request.

[0004]

However, in the conventional method, it was necessary to pick two aircrafts whose distances were to be measured from the display board. That is, when there are a plurality of aircraft whose distances are to be measured with respect to one aircraft, it is troublesome because it is necessary to manually pick two points for each aircraft and perform a measurement request operation. . In addition, it was troublesome to judge whether or not the required distance was maintained by reading the displayed distance one by one.

By the way, conventionally, in addition to the above-mentioned conventional example, the following system also exists. For example, if you set a condition that you have entered the jurisdiction of the airspace, for each aircraft that meets the conditions, the center of the aircraft and a circle with a predetermined radius are automatically displayed, and while the conditions are met, , Move the circle following the aircraft. In this conventional example, the distance relationship between the aircraft and another aircraft can be understood at a glance by constantly displaying a circle. However, in this conventional example, the distance of the aviation engine cannot be confirmed unless the set conditions are met. Also, as the circles are forcibly displayed while the conditions are met, for example, in the vicinity of the airport, the circles may overlap, making it complicated, On the other hand, it becomes difficult to know which aircraft should be paid attention to.

The present invention has been made to solve the above problems, and an object thereof is to provide a moving body position display device capable of confirming a distance relationship with a moving body by a simple operation. Especially.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1. 1 is an overall configuration diagram showing a first embodiment 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. The display device 3 for displaying the position is shown. Note that 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 figure because it is not a feature of the present embodiment. Further, although the respective devices 1 and 3 shown in the figure have devices that have existed in the related art, the components that perform the existing processing functions will not be illustrated.

The tracking processing device 1 has a position information generation processing unit 4 for generating flight position information including the flight number of each aircraft obtained as a result of the tracking process and its flight position. 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 one is used without being separately provided also in the present embodiment. .

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 the radar scans by rotating once at a predetermined time interval, for example, every 4 seconds, the flight position of each aircraft is updated every 4 seconds. Therefore, 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 the mouse 6 which is 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, and in FIG. 1, the map display control unit 7, the aircraft display control unit 8, and the cursor corresponding thereto are shown in FIG. The display controller 9 is shown.

The map display control section 7 controls the display of a map based on a map database (not shown). The aircraft display control unit 8 controls the display of the flight position of each aircraft in consideration of the scale of the map displayed on the basis of the sent flight position information. The cursor display control unit 9 controls the display of the mouse cursor on the screen, but in the present embodiment, a circle display control unit 10 that displays the cursor in a circle according to the mouse operation is provided. I am trying.

Next, the operation of the aircraft monitoring system according to this embodiment will be described with reference to the display examples shown in FIGS. It should be noted that the display of the flight number or the like identifying each aircraft is omitted from each drawing.

First, in FIG. 2, three aircraft 11, 12, and 13 that have entered the surveillance area in an attempt to land at the airport 11.
It is shown. On this display screen, the aircraft display control unit 8 displays the flight positions of the aircraft 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 visually and sensuously visually confirms whether a safe distance is maintained between the aircrafts 11 to 13 in order to ensure safety. However, when the distance is difficult to judge visually, the controller operates the mouse 6
As shown in FIG. 3, the mouse cursor 15 is placed on one of the aircrafts on the display 2 where the distance between flight positions is to be measured.
And perform a predetermined mouse operation such as left click. When the graphic display processing unit 5 receives the input by 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 controls the aircraft 12 selected by mouse operation in response to the notification.
A circle with a predetermined radius centering on the current position of is displayed. In the case of the present embodiment, the predetermined radius indicates a predetermined safety distance based on the scale of the current map.
Since the distance is constant, the display radius varies depending on the scale of the map. In the present embodiment, the arrow-shaped mouse cursor is changed to a circular shape for display. An example of this display is shown in FIG.

As described above, the aircraft 11 is displayed on the display 2.
By displaying a safe distance centering on, for example, a circle of 3 miles, it is possible to see at a glance whether or not the distance of 3 miles from the aircraft 11 is maintained. Further, in the present embodiment, one of the aircraft 11
It is easy to operate because only the mouse needs to be operated. Further, in the present embodiment, since the distance relationship is displayed as a circle, not only the relationship between the two aircraft 11 and the aircraft as the measurement object, but also the distance between the multiple aircraft between the aircraft 11 and a plurality of aircrafts. You can check the relationship at the same time.
Also, since the circle can be displayed only for the aircraft selected by the controller manually, there is no fear that it will be difficult to see when a large number of circles are displayed on the screen.

According to the present embodiment, the mouse cursor is displayed in a circular shape in accordance with the predetermined operation as described above, so that the distance between aircrafts can be confirmed by an extremely simple operation. After that, the shape of the mouse cursor can be returned to the arrow by performing a predetermined operation such as left click.

As in the present embodiment, since the purpose of checking the distance between aircrafts is clear, when the object type to which the mouse cursor is to be set is an aircraft, the display position of the mouse cursor is determined. Is constantly compared with the display position of each aircraft, and when the mouse cursor position matches the display position of any aircraft, the shape of the mouse cursor is automatically switched to a circle without accepting any mouse operation. Good. Since the position of the mouse cursor on the screen is constantly detected by the graphic display processing unit 5, the comparison can be performed in real time. When the circular cursor is displayed only by aligning the cursor positions, it is possible to return to the original arrow-shaped cursor simply by shifting the center of the circle from the aircraft. As a result, the distance relationship with another aircraft can be confirmed at a glance by a very simple operation of aligning the cursor with a target object.

Embodiment 2. In the first embodiment, the cursor display control unit 9 is provided with the circle display control unit 10 to change the shape of the mouse cursor from a general arrow to a circular shape. In the present embodiment, the circle display control unit 10 is configured differently from the cursor display control unit 9, and when the mouse cursor is selected in alignment with the flight position of the aircraft, the circle is displayed separately from the mouse cursor.

Embodiment 3. In the above-described second embodiment, a circle is displayed centering on the aircraft selected by the mouse cursor. The present embodiment is characterized in that the displayed circle is moved following the movement of the selected aircraft on the display 2.

That is, also in the present embodiment, as in the second embodiment, a circle having a predetermined radius centered on the aircraft 12 is displayed on the display 2 in response to a predetermined operation.
In the present embodiment, the circle is further separated from the mouse cursor in response to a predetermined mouse operation or a separate input instruction,
The circle is moved following the movement of the aircraft 12. That is, it can be said that the center of the circle is moved to the display position of the aircraft 12 from the cursor. Since the display position of each aircraft on the screen can be grasped, the follow-up display of the circle can be easily performed. This screen display example is shown in FIG. 5, and it can be seen that the aircraft 12 has approached the airport 11 over time. At this time, the aircraft 12
It can be seen that the circle assigned to is moving following the movement of the aircraft 12.

Further, when the scale of the map is changed in a state where the circle can be displayed for a relatively long time in accordance with the flight situation of the aircraft as in the present embodiment, the map scale on the display screen is changed according to the changed scale. It is necessary to switch the size of the radius at.

By the way, the fact that a circle can be displayed independently of the mouse cursor means that a plurality of circles may be simultaneously displayed on the screen. If it remains displayed, on the screen,
It becomes complicated. Therefore, the circle display control unit in the present embodiment has a circle display / non-display switching function, and displays the circle displayed corresponding to the aircraft in response to a predetermined operation by the controller. / Controls hiding.

Fourth Embodiment FIG. 6 shows an example of a screen display in the present embodiment, but the present embodiment is characterized in that the circles are concentric circles. As a result, it is possible not only to confirm whether or not there is a safe distance, but also to understand the distance relationship with the aircraft from the center position at a glance. In other words, in each of the above-described embodiments, the radius of the circle is set for the purpose of separating the safety / dangerous distance in order to avoid collision between aircrafts. Separately, or in addition to checking the safety distance, the radius of each circle may be set at equal intervals in order to grasp the distance relationship, and the radius can be set according to the purpose. In the above explanation, as an object to be selected by moving the mouse cursor to confirm the distance relationship with the aircraft, the aircraft which is a moving body has been described as an example, but for example, a concentric circle is displayed in accordance with the control area control center. If you make it
The distance relationship between the control center and each aircraft can be understood at a glance. The control center is not a moving body but 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 center, the concentric circles may be automatically displayed when the cursor position matches the display position of the control center, as described in the first embodiment.

As described above, according to each of the above-described embodiments, the circle centered on one point pointed by the controller is displayed, so that the two devices to be measured can be displayed with the cursor of the pointing device. You can check the distance relationship between two aircraft without pointing. Also, since the distance relationship is shown by a circle, it is obvious. In addition, the circle is displayed only for the object designated by the controller, so that the screen is not complicated.

In each of the above embodiments, a circle centering 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 understood at a glance. I chose 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, it may be displayed as an arc instead of a circle. Alternatively, only part of the circle may be displayed by the display control by the circle display control unit. The present invention also includes a case where such a circular shape is displayed in an incomplete state.

Further, although the mouse 6 is exemplified as the pointing device in the present embodiment, other devices such as a pen and a trackball may be used.

In each of the above-described embodiments, the case where the moving body position display device according to the present invention is applied to an aircraft monitoring system has been described as an example.
It can also be applied to a system for displaying birds and the like.

[0036]

According to the present invention, the distance between the position where the cursor is placed and the moving body can be understood at a glance only by performing a very simple predetermined operation of aligning the cursor position by operating the pointing device. You can

Further, since the circle is made to follow the moving body, even if the moving body moves, the distance relationship between the moving body and another moving body can always be confirmed.

Since the display / non-display of the circle can be switched, it is possible to prevent the displayed circle from complicating the screen.

Further, since the circles are concentric circles, the distance relationship from the center can be understood at a glance.

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.
