Abstract

The invention discloses an airport runway foreign matter monitoring system based on the laser phased array technology and relates to the technical field of laser coherent control technology and the technical field of laser radar. The problems of a long detection period of a walking or driving low-speed inspection mode of an airport runway and a short service life in camera scanning are solved. Aninformation acquisition terminal comprises a laser, a laser phased array transmitting and receiving device, a controller, a first optical transceiver module, a two-dimensional adjusting bracket and apower adapter. The power adapter supplies power to the laser, the controller, the laser phased array transmitting and receiving device and the first optical transceiver module. The laser, the laser phased array transmitting and receiving device, the controller, the first optical transceiver module and the power adapter are fixed on the two-dimensional adjusting bracket. The intelligent informationprocessing system comprises a computer workstation, a second optical transceiver and a UPS (uninterrupted power supply), and the UPS carries out anti-outage protection on the computer workstation andthe second optical transceiver module. According to the invention, the runway can be scanned uninterruptedly, and the monitoring and checking period of a same road section is short.

Description

technical field [0001] The invention relates to the fields of laser coherent control technology and laser radar technology, in particular to a monitoring system for a foreign object monitoring system on an airport runway based on laser phased array technology. Background technique [0002] The environmental requirements of the airport runway are relatively strict. Therefore, the cleaning of the airport runway is also very important. The usual methods for checking foreign objects on the runway are as follows: [0003] 1. Manual on-site inspection; inspectors walk or ride slowly along the runway for periodic inspections. This method has a long monitoring and inspection period for the same road section, generally more than tens of minutes; and it cannot realize real-time monitoring. [0004] 2. Mechanical imaging scanning: It is proposed to use the camera to scan the airport runway area, and then identify whether there is a foreign object. Due to the mechanical scanning, the n...
