Aircraft address code conflict detection method and system based on ads-b

Abstract

The invention discloses an ADS‑B-based aircraft 24-bit address code conflict detection method and system, which includes receiving an S-mode message sent by the aircraft, and obtaining the 24-bit address code of the S-mode message; in a pre-established target database Find the aircraft information that matches the 24-bit address code; determine the S-mode message type based on the aircraft information, and when the S-mode message type is an S-mode position message, solve the position information by CPR decoding; determine 24 based on the position information The target position of the 24-bit address code conflict; and determine the effective status information of the message according to the conflict identifier added to the target position of the 24-bit address code conflict. The above solution can accurately detect conflicting 24-bit address code targets at the data source end of ADS‑B and multipoint positioning.

Description

technical field [0001] The invention belongs to the technical field of aviation control, in particular to an ADS-B-based aircraft address code conflict detection method and system. Background technique [0002] In recent years, ADS-B and multilateration have been gradually adopted in China as new surveillance technologies and pushed to the foreground of technical applications. Both ADS-B and multilateration are based on processing aircraft Mode S signals to provide controllers with real-time traffic situation information. The S mode signal mainly includes information such as the position, altitude, speed, heading, and identification number of the aircraft. This information plays an important role in ensuring the safe implementation of civil aviation control tasks. Among the Mode S signals, the most critical is the position information of the aircraft. Proper processing and parsing of the location information in the Mode S message is particularly important in surveillance ...

AI Technical Summary

Problems solved by technology

[0005] 1) When the S-mode transponder of the airborne equipment fails, the 24-bit address code issued by the aircraft is wrong, which may cause the target to conflict with the 24-bit address code of other normal aircraft. If you simply use 2 24-bit The address code distinguishes the aircraft target, which will cause wrong data association, resulting in false targets and missing targets on the data source

[0006] 2) The 24-bit address code conflict between multi-point positioning and ADS-B should be caused by the problem of the airborne equipment, and the wrong target information was sent to the automation system, which caused the back-end automation system to fail to integrate data normally, requiring manual confirmation by the controller. Possess certain risks to normal regulated business
