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

The invention provides a method, system and server for transmitting airport scene surveillance radar data based on a 4G private network. The transmission method includes: obtaining the airport surface surveillance radar data; filtering the airport surface surveillance radar data according to the latitude and longitude data and data content, and retaining the data in a given area of the airport with available content; merging the reserved data packets; filtering based on time Packets, send after merging packets. The present invention overcomes the shortcomings of the airport surface surveillance radar, such as wide airspace coverage, large data volume, and short individual data, by obtaining the airport surface surveillance radar data, and filtering, merging and screening the obtained data, so that the processed data It is more suitable for the transmission of 4G private network, the packet loss rate is low, and it can also avoid the interference to airport users caused by the introduction of scene surveillance radar data into the 4G network and the excessive bandwidth occupied.
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...
