Hereinafter, the present invention will be described based on the illustrated embodiment.

(Embodiment 1)
FIG. 1 is a schematic configuration diagram showing a remote control system 1 according to this embodiment. This remote control system 1 is a system for controlling a moving body from a remote place. In this embodiment, the moving body is an aircraft A, the controlled place is an airport P, and a flight assistance center is located in a remote place away from the airport P. A case where F is provided will be described.

At the airport P, an anti-aircraft radio 21, an RVR (mobile information acquisition means) 22, an MLAT (mobile information acquisition means) 23, and a wind direction anemometer (not shown) are provided. The anti-aircraft radio 21 is a radio used for air traffic control to communicate and talk with the aircraft A. The RVR 22 is a device for observing and acquiring a viewing distance (moving body information), which is a visible distance on the runway. Here, the viewing distance changes depending on the weather, time (morning and evening), season, and the like, and if the viewing distance is different, the view from the airport P (an image of the moving object A described later) is also different. In addition, the viewing distance is observed and acquired at all times (regularly).

As shown in FIG. 2, the MLAT23 receives a signal (skitta) transmitted from the transponder of the aircraft A at three or more receiving stations 23a, and the position (moving body information) of the aircraft A and the position (moving body information) of the aircraft A are determined from the difference in reception time. This is a multilateration system that measures and acquires flight numbers (moving object information) of aircraft A. Here, in this embodiment, if the flight number of the aircraft A is the same, the model and model of the aircraft A are also the same. In addition, the position includes the direction and altitude, and the position is measured and acquired at all times (regularly).

These anti-aircraft radios 21, RVR 22 and MLAT 23 are connected to the airport server 24 in the airport P. Then, the communication contents by the anti-aircraft radio 21, the viewing distance acquired by the RVR 22, the position of the aircraft A acquired by the MLAT 23, the flight number, etc. are aggregated in the airport server 24 in real time and the flight assistance is provided via the communication device 25. It is designed to be transmitted to the center F side.

The flight assistance center F is provided with a control terminal (image processing means) 32, an image database server (image storage means) 33, and an anti-aircraft radio 34, which can communicate with the airport P side via the communication device 31. ing. Like the anti-aircraft radio 21, the anti-aircraft radio 34 is a radio used for air traffic control and for communicating with the aircraft A. That is, the controller in the flight assistance center F communicates with the aircraft A via the anti-aircraft radio 34 and the anti-aircraft radio 21.

The image database server 33 is a database server that stores an image of the aircraft A viewed from the airport P in association with the position of the aircraft A. That is, it is a server that stores an image of a view of the aircraft A from a predetermined location (for example, a control tower) of the airport P for each position of the aircraft A. Specifically, as shown in FIG. 3, the position 332, the model 333, the weather 334, the viewing distance 335, the image 336, and the other 337 are stored for each image ID 331.

The image ID 331 stores the identification information of the image, the position 332 stores the position (including the direction and altitude) of the aircraft A when the image was taken, and the model 333 stores the image. The model and flight number of the aircraft A in the image are memorized. The weather 334 stores the weather when the image was taken, and the viewing distance 335 stores the viewing distance when the image was taken. The image 336 stores an image of the aircraft A viewed, and may be either a still image or a moving image. For example, a still image as shown in FIG. 4 is stored. As described above, in this embodiment, the image is stored in association with the position of the aircraft A (moving body information), the model of the moving body A (moving body information), the weather and the viewing distance (moving body information). ..

The control terminal 32 is composed of a general-purpose computer, and includes an input unit 35 and a display unit (display means) 36. The input unit 35 is an interface for inputting various information and commands, and is composed of a keyboard, a mouse, and the like. The display unit 36 is a display for displaying various information and images, particularly an image stored in the image database server 33, and as shown in FIG. 5, is composed of a plurality of panels 361 and can be displayed on a large screen. ing.

Further, an image processing task (image processing means) is installed in the control terminal 32. This image processing task is a task program that acquires an image matching the position of the aircraft A acquired by the MLAT 23 from the image database server 33 and displays it on the display unit 36. That is, it is activated when a command to start control is input by the input unit 35, and as shown in FIG. 6, first, the moving body information is received and acquired (step S1). That is, the viewing distance acquired by the RVR 22 of the airport P, the position and the model of the aircraft A acquired by the MLAT 23 are received and acquired via the communication device 31.

Next, an image matching these mobile information is searched from the image database server 33 (step S2). That is, the image database server obtains the image ID 331 of the model 333 that matches or approximates the acquired position of the aircraft A, the model of the acquired aircraft A, and the viewing distance of 335 that matches the acquired viewing distance. Search from 33. At this time, if there is no image ID 331 that matches all the moving body information, the moving body information is searched by giving priority or weighting. For example, the position of the aircraft A is set to the first priority, the model of the aircraft A is set to the second priority, and the viewing distance is set to the third priority, and the image ID 331 that matches a lot of high-priority moving body information is searched. To do. Here, in this embodiment, a case where an image of the background and the aircraft taken together is stored in the image database server 33, searched, and displayed will be described. However, the background and the image of the aircraft are separately stored and moved. Each image matching the body information may be searched, combined, and displayed on the display unit 36.

Subsequently, as shown in FIG. 7, the image stored in the image 336 of the searched and acquired image ID 331 is output to the display unit 36 and displayed (step S3). Such processing (steps S1 to S3) is repeated until the control is completed (until it becomes "Y" in step S4). In this way, each time the mobile body information is received from the airport P side, images matching the mobile body information are sequentially displayed on the display unit 36. As a result, it is possible to always obtain a view as if the aircraft A is being viewed at a predetermined location of the airport P.

Next, the operation of the remote control system 1 having such a configuration, the remote control method by the remote control system 1, and the like will be described.

First, when the image processing task of the control terminal 32 is activated, the viewing distance is acquired by the RVR22 of the airport P, and the position and model of the aircraft A are acquired by the MLAT23, these moving object information is transmitted to the airport server. It is transmitted to the flight assistance center F side via the 24 and the communication device 25. When the communication device 31 receives the mobile body information, an image matching the mobile body information is searched and acquired from the image database server 33, and this image is displayed on the display unit 36. Such image display is performed every time the moving body information is received, that is, every time the position of the aircraft A or the like changes. Then, while looking at this image, the controller communicates with the aircraft A via the anti-aircraft radio 34 and the anti-aircraft radio 21, and controls the aircraft.

As described above, according to the remote control system 1 and the remote control method, an image suitable for moving object information such as the position of the aircraft A may be acquired from the image database server 33 and displayed on the display unit 36. Therefore, it is not necessary to send and receive an image of the aircraft A viewed from the airport P. That is, since the image corresponding to the position of the aircraft A may be stored in advance, the moving body information including the position of the aircraft A may be acquired, and the image matching the moving body information may be acquired and displayed, a real-time image may be obtained. No need to send or receive. Therefore, even when the flight assistance center F in a remote location controls the air traffic control, it is not necessary to provide a large-capacity communication line between the airport P and the flight assistance center F. Further, in order to acquire an image that matches the moving object information, an appropriate image corresponding to the position of the aircraft A and the like is displayed, and it is possible to control the aircraft remotely and appropriately.

In addition, since the moving body information includes the viewing distance and the moving body information, that is, an image matching the viewing distance is acquired, an appropriate (highly realistic) image according to the viewing distance as well as the position of the aircraft A is displayed. Therefore, it becomes possible to control more appropriately remotely. Furthermore, since the mobile information includes the flight number and model of aircraft A, and the mobile information, that is, an image matching the model of aircraft A is acquired, it is appropriate not only for the position of aircraft A but also for the model of aircraft A. Images are displayed, and it is possible to control more appropriately remotely.
