Airborne collision avoidance system, ACAS transmit-receive host digital signal loop self-detection system and method

Abstract

The invention discloses an airborne collision avoidance system, an ACAS transmit-receive host digital signal loop self-detection system and a method. Without increasing extra hardware equipment, equipment original composition modules of a JSCPU, a coding FPGA, a decoding module, an FZCPU and inherent communication channels thereof are employed to work in a cooperative manner, and software programming is realized. According to the airborne collision avoidance system, the ACAS transmit-receive host digital signal loop self-detection system and the method, digital signal loop self-detection of an ACAS transmit-receive host can be automatically, periodically, and effectively realized, and the self-detection result is reported to a carrier aircraft maintenance system for fault display and record; real-time fault monitoring is performed in the whole work stage of the airborne collision avoidance system, functional module level fault positioning can be accomplished, fault isolation is effectively realized, maintenance and guarantee are facilitated, and the requirements of equipment tests and maintenance are met; host inherent hardware resources are employed in the manner of software programming, test equipment and manual intervention are not needed, the costs of manpower and material resources are effectively lowered, the testability and maintainability of the equipment are improved, and equipment production and maintenance are facilitated.

Description

technical field [0001] The invention relates to the field of airborne anti-collision technology, in particular to an airborne anti-collision system, an ACAS transceiver host digital signal loop self-inspection system and a method. Background technique [0002] The airborne collision avoidance system (ie TCAS-Traffic Alert and Collision Avoidance System) is defined by the Federal Aviation Administration (FAA) and is an essential device to prevent dangerous approach and collision accidents of air planes. 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 ...

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
