Airport runway foreign body monitoring system and method

Abstract

The invention relates to an airport runway foreign body monitoring system and method. The system includes an FOD private network which is connected with a plurality of FOD monitoring points, a wireless access point, a data center, a control center an airport private network; the wireless access point is connected with a handheld mobile terminal to obtain feedback, access and foreign body information and send foreign body cleaning instructions; the FOD private network obtains flight plans, foreign body confirmation instructions, monitoring point control instructions, database operation instructions, monitoring point control instructions, data fusion results and video splicing signals, and obtains monitoring point returned information, foreign body information, feedback information, access information and the state information of the control center; the data center obtains the FOD monitoring point control instructions, the database operation instructions, the returned information, the feedback information, the access information, the state information of the control center and the wireless access point; the control center obtains the flight plans, the data fusion results and the video splicing signals; and the FOD monitoring points obtain the foreign body confirmation instructions to confirm foreign body information. With the airport runway foreign matter monitoring system and method of the invention adopted, false alarm can be effectively reduced, and the reliability of a system can be improved.

Description

technical field [0001] The invention belongs to the technical field of object detection and recognition in the field of image recognition, and in particular relates to a monitoring system and method for foreign objects on airport runways. Background technique [0002] Achieving complete surveillance of the runway is very important for safe airport operations. At busy airports, runways are constantly being damaged due to frequent use by aircraft and other vehicles, producing damage such as potholes. Occasionally, there will be foreign objects on the runway due to aircraft takeoff and landing, wake turbulence and other reasons. These foreign objects can cause air crashes, casualties and economic losses to airlines. [0003] In response to the above problems of the airport runway, the industry adopts different methods to monitor the runway: for example, the traditional manual inspection of the runway surface relies on the staff to regularly walk on the runway and walk accordi...

AI Technical Summary

Problems solved by technology

However, the use of radar systems for runway surveillance has its limitations: radar has a very high detection effect on metallic objects, but is not sensitive to non-metallic objects such as rubber; radar blind spots and other obstacles cannot be completely avoided by using radar systems Or the influence of fixed facilities (for example) on the detection results; it is also difficult to rule out foreign object false alarms caused by strong signals reflected by some tiny metal objects

In addition, the image formed by the infrared or thermal imaging system loses information such as the edge and color of the object, which is not conducive to the confirmation and resolution of foreign objects

[0006] There are also some airports that use video cameras to find and identify foreign objects through the video camera’s return image signal for processing. However, this method of using video cameras also has some problems: it does not have a wide range of adaptation to the complex and changeable airport runway environment , will generate a large number of false alarms

[0011] The appearance of Trex's Fodfinder system, TrexEnterprises' vehicle-mounted Fodfinder system, has two styles: the first model: FodfinderXM series, which uses millimeter-wave radar detection, and is equipped with an optical camera for confirmation. The radar antenna and optical camera are installed on the top of the vehicle; The working frequency band of the millimeter wave radar is 77-81GHz. During the vehicle-mounted operation, the runway needs to be closed, and the runway is used for detection, which occupies the runway, so the utilization rate of the runway is not improved.
