Airport scene monitoring radar data transmission method, system and server

Abstract

The embodiment of the invention provides an airport scene monitoring radar data transmission method and system based on a 4G private network, and a server. The transmission method comprises the stepsof acquiring airport scene monitoring radar data comprising flight numbers and longitude and latitude position information corresponding to each flight; filtering the airport scene monitoring radar data according to the longitude and latitude data and the data content, and reserving data with available content in a given area range of an airport; combining the reserved data packets; and screeningthe merged data packets based on time. According to the airport surface monitoring radar data transmission method based on the 4G private network, the airport surface monitoring radar data is obtained, and the obtained data is filtered, merged and screened, so that the defects of wide coverage airspace, large data volume and short and small single data of the airport surface monitoring radar are overcome; the processed data is enabled to be more suitable for the transmission of a 4G private network, the packet loss rate is low, and the interference to airport users caused by the too high bandwidth occupied by the 4G network introduced into the scene monitoring radar data can be avoided.

Description

technical field [0001] The invention relates to the field of operation of special vehicles for airport scenes, in particular to a method, system and server for transmitting airport scene monitoring radar data based on a 4G private network. Background technique [0002] Special vehicles for airport scenes are an extremely important link in the air transportation chain. The normal operation of aircraft requires the guarantee of various ground service vehicles such as guide vehicles, tractors, shuttle vehicles, luggage delivery vehicles, food vehicles, and refueling vehicles. [0003] In order to ensure the reliability of the operation of special vehicles on the airport scene, there are currently applications of special vehicles based on ADS-B IN technology on airport surface traffic situational awareness enhancement technology, but this type of application only relies on the ADS-B data issued by the aircraft as a single Data source, there are the following three types of probl...

AI Technical Summary

Problems solved by technology

[0004] 1) The flight number information of the aircraft cannot be obtained due to improper operation by the crew;

[0005] 2) The traffic situation information of the aircraft cannot be obtained because the aircraft did not turn on the ADS-B OUT system as required;

[0006] 3) The ADS-B data of some aircrafts is unavailable due to signal occlusion on the ground;

[0008] Supplementing the data of the airport surface surveillance radar is the current research direction of the applicant, but the difficulty in the data fusion technology based on the aircraft ADS-B and the airport surface surveillance radar is: the data of the airport surface surveillance radar is transmitted to the airport surface special vehicles. What kind of preprocessing needs to be adopted before the on-board processing, so as to make it more suitable for the transmission of the 4G private network, and form a more effective compensation for the data of the aircraft ADS-B fusion
