Collision avoidance system based on ADS-B

Abstract

The invention discloses a collision avoidance system based on ADS-B, including: an ADS-B information decoding module used to decode the received ADS-B information of the neighboring machine, and calculate the position information of the neighboring machine; a anti-collision information processing sub-module used for converting the position information of the neighboring machine into the angle of the neighboring machine relative to the local machine, the distance, the height and the time stamp of the neighboring machine relative to the local machine, confirming whether the neighboring machine is tracked, and then sending the tracing information list to the anti-collision information processing module; an anti-collision information processing sub-module used for converting the position information of the neighboring machine into the distance, the height and the time stamp of the neighboring machine relative to the local machine. The invention can reduce the dependence on the radio frequency module in the traditional TCAS, simplify the equipment, reduce the cost and is more suitable for the use of the light aircraft or the unmanned aerial vehicle, reduce the frequency of the inquiry sending and reduce the interference to the airspace wireless environment.

Description

technical field [0001] The invention relates to an airborne collision avoidance system which combines an ADS-B system and a TCAS system, and belongs to the field of aviation technology. Background technique [0002] The traditional air collision avoidance system mainly relies on TCAS (Traffic Alert and Collision Avoidance System). Its prediction of conflicts can only rely on the current and historical position and speed information obtained. The ability to predict conflicts will be greatly reduced as the complexity of route flight increases. Inability to be sufficiently flexible to adapt to the evolution of airspace management. In order to improve the performance of TCAS, the existing design principles of Collision Avoidance System (CAS) need to be updated and more effective input data should be introduced. Automatic Dependent Surveillance (ADS-B) technology can improve mutual surveillance capabilities between aircraft in flight. Compared with TCAS, the position report of ...
