Abstract

The invention discloses a method and system for analyzing ADS-B message data. The method is specifically as follows: first, define a multi-level joint extensible structure; then analyze the validity of the ADS-B message; and then analyze the ADS-B The type of the message is analyzed; and then the content of the ADS-B message is analyzed. The method can quickly, efficiently and flexibly analyze ADS-B messages; in addition, by performing fault-tolerant processing on the parsed ADS-B message structure, the accuracy, stability and reliability of ADS-B message data analysis can be improved .

Description

technical field

[0001] The invention relates to the technical field of aviation control, in particular to an ADS-B message data analysis method and system. Background technique

[0002] Traditional secondary radar monitors targets based on inquiry and response methods. Due to high cost, difficulty in installation, and difficulty in comprehensive coverage, it has been unable to meet the rapidly developing air transport industry. Automatic Dependent Surveillance-Broadcast (ADS-B) is a new air traffic monitoring technology based on the global satellite positioning system and using air-ground and air-air data link communications to complete traffic monitoring and information transmission. Improve airspace utilization. 1090MHz ES ADS-B is the only mode recommended by the International Civil Aviation Organization. The system can realize ADS-B message encoding only by slightly modifying the Mode S transponder. Compared with the traditional surveillance technology, the ADS-B syste...

Embodiment Construction

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.

[0022] A kind of ADS-B message data analysis method provided by the present invention, its flow process is as follows figure 1 As shown, the specific process is as follows:

[0023] Step 1: Define a multi-level joint extensible structure.

[0024] The structure of the multi-level joint extensible structure is as follows figure 2 shown. The multi-level joint extensible structure includes the general structure of the first layer of ADS-B message and the special structure of the second layer of ADS-B message.

[0025] Among them, the first-layer general structure of the ADS-B message...
