Abstract

Aiming at the fault phenomenon of RS422 communication interruption between devices in an on-board system, on the basis of understanding the composition principle of on-board system, fault tree analysis method is used to locate the fault point quickly. In order to find out the root cause of the failure point, the failure point is analyzed, and the circuit improvement suggestions are put forward according to the analysis results, which provides the direction and theoretical basis for the design of RS422 communication circuit with high quality and high reliability.
