Airborne collision avoidance system, acas transceiver host self-inspection system and method

Abstract

The invention discloses an airborne anti-collision system, an ACAS transceiver host self-inspection system and a method. Under the condition of not adding additional hardware equipment, use the original components of the equipment JSCPU, encoding FPGA, receiver module, decoding module, receiver module and FZCPU and their inherent communication channels to work together, and realize software programming. The invention can automatically, periodically and effectively realize the self-test of the receiving loop and the digital signal loop of the ACAS transceiver host, and report the self-test result to the carrier maintenance system for fault display and recording. Real-time fault monitoring is carried out during the entire working stage of the airborne collision avoidance system, which can complete fault location at the functional module level, realize effective fault isolation, facilitate maintenance and support, and meet equipment testing and maintenance requirements. At the same time, because the present invention uses the inherent hardware resources of the host computer to realize it through software programming, it does not require testing equipment and manual intervention, effectively saving manpower and material costs, improving the testability and maintainability of the equipment, and facilitating equipment production and maintenance.

Description

technical field [0001] The invention relates to the technical field of airborne collision avoidance, in particular to an airborne anti-collision system, an ACAS transceiver host self-inspection system and a method. Background technique [0002] Airborne collision avoidance system (TCAS-Traffic Alert and Collision Avoidance System), defined by the Federal Aviation Administration (FAA), is an essential device to prevent dangerous approach and collision accidents of aircraft in the air. TCAS is mainly used to provide air safety separation guarantee for aircraft. The system uses secondary radar to detect approaching aircraft in the nearby airspace. When necessary, it reminds pilots to take evasive measures to maintain an appropriate safe distance from other aircraft to achieve the purpose of collision avoidance. The flight practice in recent years has proved that this system is the last line of defense to prevent aircraft collisions in the air, and it is also one of the most eff...

Problems solved by technology

[0005] The traditional detection method needs to be equipped with special testing personnel to use special supporting test equipment to build a working platform, and simulate the system use environment to conduct corresponding tests, which is costly and inefficient.

At the same time, due to the human error in the instrument observation, the test accuracy is affected

When a problem occurs during the use of the equipment in the field, it is often impossible to isolate the fault due to the lack of corresponding detection conditions. To locate the location of the fault, the only way to return the whole machine to the factory for repair is not conducive to the fault location and maintenance of the equipment. Maintenance Guarantee
