Description

technical field [0001] The invention relates to the technical field of field and lane safety monitoring in airport flight areas, in particular to a grating array coding method and device for airport field lane safety monitoring. Background technique [0002] In recent years, with the sharp increase in the volume of tourism travel and logistics transportation, the number of aircraft take-offs and landings has increased, the density of flights has increased, and the operating time of airports has been extended. The direct impact is that while the frequency of damage to infrastructure such as airport roadways increases and the service life decreases, the time for maintenance and repair of skylights is shortened, which makes the airport's safety management pressure and operation and maintenance costs rise sharply. Therefore, it is urgent to use advanced sensing technology to conduct comprehensive and real-time monitoring of various performance parameters of the airport pavement ...

Problems solved by technology

[0003] Among the existing monitoring technologies, image acquisition and positioning technologies such as video, radar, and GPS are generally used to monitor various carriers (such as aircraft and vehicles) on the airport track, but these technologies can only obtain the position of the carrier, Information such as speed cannot obtain the response of the carrier to the pavement structure and the internal information of the pavement; for the monitoring of key areas such as take-off and landing of airport runways, traditional electrical sensing technologies are mostly used at present, and some airports have also adopted optical fiber in recent years. Although sensing technology can realize multi-parameter monitoring in local areas, most of these technologies are based on point sensors, which are difficult to form large-scale networks and long-distance signal transmission. It is impossible to obtain comprehensive and multi-parameter information on the airport track, and it is difficult to realize the automatic monitoring and intelligent management of the airport track status. In addition, due to the large area, complex structure and many monitoring parameters of the airport track, how to integrate the engineering structure grid unit with the transmission Associating the sensing units of the sensing network is an urgent technical problem to be solved
