Description

Technical Field

[0001] The invention relates to the technical field of ground devices associated with airports and aircraft, and in particular to an intelligent control device for close-range monitoring of aircraft runways. Background Art

[0002] The takeoff and landing locations of aircraft on the runway of an airport include the taxiway takeoff surface and the touchdown zone. Because it is directly related to aircraft safety, it has always been the focus of air defense safety at various airports. However, due to the fact that the height of obstacles on the takeoff and landing strips of the airfield, including the runway, shall not exceed 35 cm and must be easily foldable (to prevent damage to the aircraft in the event of a collision with the aircraft), and the long distances for power supply and signal transmission, close-range monitoring is difficult to achieve. In particular, when an accident occurs due to a malfunction of the aircraft landing gear, it is difficult for the airport to obtain accurate on-site evidence in a timely manner, except for obtaining evidence through the aircraft black box.

[0003] At present, the technical means used by various airports for runway monitoring mainly include:

[0004] 1. Panoramic or long-distance monitoring. Cameras are installed at the control tower and terminal for long-distance monitoring, which can observe the take-off and landing of aircraft, but cannot monitor the ground FOD (foreign objects, including invasive small animals) or the landing or take-off of aircraft landing gear at close range.

[0005] 2. Runway FOD monitoring. Video surveillance and radar are installed outside the flight zone take-off and landing strip and within the transition surface restricted height to monitor runway FOD to ensure aircraft safety. However, the distance from the runway centerline is usually more than 200m, making it impossible to conduct close monitoring of the aircraft take-off and landing process and the landing or take-off of the landing gear.

[0006] 3. Install a fixed surveillance camera with a height of no more than 35 cm on the surface area about 50 meters away from one side of the runway to monitor the take-off and landing of aircraft. However, it is impossible to track and monitor aircraft, nor is it possible to monitor FOD on the pavement. Especially in summer, overgrown weeds often block the line of sight of the surveillance camera, seriously affecting the monitoring effect.

[0007] The above-mentioned technical means all adopt wired transmission mode. When technical personnel debug and maintain the front-end equipment on site, they usually need the cooperation of the platform on-duty personnel to observe the debugging effect, which is very inconvenient.

[0008] Therefore, based on the above problems, it is very necessary to design an intelligent control device for close-range monitoring of aircraft runways. Summary of the invention

[0009] The purpose of the present invention is to provide an intelligent control device for close-range monitoring of an aircraft runway, which can realize close-range monitoring of the aircraft take-off and landing process, the landing or take-off condition of the landing gear, and the pavement FOD, and can be networked with the tower air traffic control command system and the FOD monitoring system for monitoring. When an abnormal situation occurs, the tower air traffic control personnel can promptly issue instructions to the aircraft to prevent accidents, collect evidence in time, and promptly notify the field staff to eliminate faults or FOD. At the same time, the technical problem of wireless transmission of close-range images on site is solved, and the efficiency of equipment debugging and maintenance is improved.
