For the goal of improving the safety of aircraft taking-off and landing, studied the detecting method of monitoring abnormal on runway, mainly used laser transceiver devices, wireless networks, wireless handsets to achieve the target. laser transceiver devices was responsible for monitoring the runway pavement; the wireless transmission network node collected data that had been monitored, and made them compared with the standard data, and judged whether there were foreign matters or pavement damage depending on whether there were mutations values. Wireless networks determined the location of fault according to mutation values and sent information to field service personnel to achieve fast and high efficient processing failures runway action and reduce the risk of flight.
