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

Embodiment Construction

[0045] Under the condition of not adding additional hardware equipment, the present invention utilizes the original component modules of the equipment: JSCPU, encoding FPGA, receiver module, decoding module, FZCPU and their inherent communication channels to work together, software programming realizes its composition block diagram like figure 1 shown. The JSCPU, the decoding module, the FZCPU, and the receiver module are respectively connected to the encoding FPGA, and the decoding module is connected to the JSCPU and the receiver module. During the entire working process of the equipment, the self-inspection keeps running periodically at a frequency of 1s / time, and the FZCPU will report the self-inspection fault code to the aircraft maintenance system for fault display and recording.

[0046] Each module is described below.

[0047] The JSCPU is used to issue the C-mode closed-loop self-test command or the S-mode closed-loop self-test command to the encoding FPGA, receive ...

Abstract

The invention discloses an airborne anti-collision system, an ACAS transceiver host receiving loop self-checking system and a method. Under the condition of not adding additional hardware equipment, the original components of the equipment JSCPU, encoding FPGA, receiver module, decoding module and FZCPU and their inherent communication channels are used to work together, and software programming is implemented. The invention can automatically, periodically and effectively realize the self-test of the receiving 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 field of airborne anti-collision technology, in particular to an airborne anti-collision system, an ACAS transceiver host receiving loop 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 t...
