Airfield runway foreign object detection system

Abstract

The invention relates to an airfield runway foreign object detection system which comprises laser scanning devices, imaging devices, an alarm device, a display device, a control system, and the like, wherein multiple groups of the laser scanning devices and the imaging devices corresponding to the laser scanning devices are provided as well as arrayed and arranged at both sides of an airfield runway; and laser scanning and imaging signals are transmitted to the control system and the display device through transmission lines. In the airfield runway foreign object detection system, the characteristic of high precision of laser is utilized, thus smaller foreign objects on the airfield runway can be detected, and the physical coordinate positions of the smaller foreign objects can be determined; and the imaging devices are used for providing visual and visible image information for staff so as to be convenient for confirming and processing alarm targets for the staff. The system can be used for monitoring the airfield runway around the clock for 24 hours without being influenced by environment, thereby false alarms are reduced. Meanwhile, the system can automatically carry out detection during the period of a regular flight without influencing the normal operations of the airport.

Description

【Technical field】 [0001] The invention relates to an airport runway foreign object detection system, in particular to an airport runway foreign object (Foreign Object Debris) detection system based on the combination of laser scanning technology and imaging technology. 【Background technique】 [0002] Whenever a plane takes off or lands, pilots expect to see lights and guide lines on the runway, not foreign objects. A foreign object present anywhere on an airport runway can damage an aircraft or injure passengers. For a long time, timely detection and removal of foreign objects has been a difficult problem for airport security technicians to overcome. Therefore, an efficient and practical foreign object detection system will not only increase the safety factor of the airport runway, ensure the normal take-off and landing of the aircraft, but also improve the efficiency and benefit of the airport operation. [0003] The existing detection technologies mainly include radar de...

Problems solved by technology

However, the camera and video system of the system are easily affected by brightness and weather, and have many limitations in the case of low visibility, and the performance is also affected and restricted by the dark night and rainy weather environment;

[0006] 2. Domestic airport runway safety monitoring system. The system is equipped with a large multiple telephoto lens and cooling infrared thermal imaging to realize long-distance day and night monitoring of several kilometers to tens of kilometers. Because infrared thermal imaging does not need visible light at all, it can provide sharp and clear thermal images in total darkness, mist or smog, and truly achieve 24-hour monitoring, but the system's red thermal imaging cannot be detected at night.
