Example Embodiment

[0047] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following implementation. example.

[0048] like Figure 4 As shown, the automatic detection and warning system for foreign objects on the airport runway involved in Embodiment 1 includes: a detection device 1 for real-time detection and acquisition of position data and optical feature data of foreign objects on the airport runway. The optical feature database 2 is used to record and store the position data and optical feature data of the object. The object motion state analysis device 3 is used to analyze the coordinate position of the object and whether it is a moving object according to the position data of the object. The object physical property a...

Abstract

The invention provides a system and method for automatically detecting foreign object debris (FOD) on airfield runways, belonging to the technical field of automatic control of aviation. The system comprises a detector, an optical characteristic database, an FOD database, an object motion state analysis device, an object physical attribute analysis device, an estimation device of threat severity grade of the object towards the airplanes, an alarm device, a remote monitoring device and a workstation removing device. By the system and the method, all-day, all-weather and full-automatic detection, identification and alarm can be carried out on the FOD targets and the accuracy of automatic detection and alarm can be substantially improved.

Description

technical field [0001] The present invention relates to a device and method in the field of aircraft and airport technology, in particular to an automatic foreign object detection system and detection method for airport runways. Background technique [0002] With the substantial increase in passenger traffic at civil airports, the number of incidents of foreign objects (Internationally known as: Foreign Object Debris (FOD)) falling on airport runways has increased significantly. Typical examples of foreign objects include: concrete asphalt fragments, metal devices, rubber Debris, plastic, flora and fauna. [0003] Aircraft are quite fragile to FOD. A bird or a small piece of plastic sheet sucked into the engine may cause an air stop. A small screw or metal piece or even a sharp stone may puncture the tire and cause an explosion. The resulting tire fragments may damage the aircraft body Or important parts, such as hydraulic pipes, fuel tanks. The FOD event that attracted th...
