The invention discloses an
airborne collision avoidance system, an ACAS transmit-receive host self-detection
system and a method. Without increasing extra hardware equipment, equipment original composition modules of a JSCPU, a coding FPGA, a
receiver module, 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 self-detection
system and the method, reception loop and
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.
