| Abstract: | Aiming at the typical functional hazard scenarios and architecture design process of TCAS system operation
process, aforward design process method of system engineering processa fault detection and fault tolerance design technology
is performed on theresearch of TCAS system domain in view of the potential functional failure risk, and a fault
detection and isolation architecture design scheme is designedto cover the system software and hardware design levels,
so as to improve the creditof anti-collision alarm during installation and operation, and to reduce the impact of flight
safety due to missed alarm and false alarm. |
