Abstract:

This paper presents a kind of multi buses automatic diagnosis system which is suitable for missiles. The diagnosis analysis of multi bus mainly includes the diagnosis analysis of the electrical layer and data link layer of multi bus .The scheme, hardware architecture and software design of the diagnosis system are discussed, and the realization principle and technical characteristics of the system are described. The test shows that the automatic diagnosis system can analyze all kinds of technical characteristics and communication protocols of the bus data in real time, and record the bus data in real time, so as to evaluate the bus and network comprehensively, diagnose the problems in the network quickly, and improve the ability of locate and analyze problems.
