Anti-collision system based on ads-b

Abstract

The invention discloses an ADS-B-based anti-collision system, comprising: an ADS-B information decoding module: used to decode the received ADS-B information broadcast by a neighboring machine, and calculate the position information of the neighboring machine; ADS-B B monitoring and tracking processing module: used to convert the position information of the neighboring machine into the angle of the neighboring machine relative to the own machine, the distance, height and time stamp of the neighboring machine relative to the own machine, and confirm whether the neighboring machine is tracked, and then The tracking information list is sent to the anti-collision information processing sub-module; the anti-collision information processing sub-module is used to use the anti-collision algorithm to process the angle, distance, height and time stamp of the adjacent aircraft in the tracking information list, and make an anti-collision alarm decision-making and traffic alert decision-making. The invention can reduce the dependence on the radio frequency module in the traditional TCAS, simplify the equipment and reduce the cost, and is more suitable for light aircraft or unmanned aerial vehicles. At the same time, the frequency of query sending is reduced, and the interference to the airspace wireless environment is reduced.

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 ...
