Locomotive Electric Transmission Circuit Fault Diagnosis System

In this paper, the fault diagnosis system of the locomotive electric transmission circuit is studied and designed. The fault diagnosis system is used to rapidly and exactly judge whether the electric transmission circuit is normal and to help the driver to find the solution to the fault, when the locomotive can't run correctly.The fault diagnosis system of the locomotive electric transmission circuit described above is an application system, which include of signal sampling, data transmission and fault identification. In this paper, the electric technology, computer technology and artificial intelligence are adopted and the on-line fault identification of the DF11 locomotive electric transmission circuit is elementarily discussed and studied. All the expert system consists of the single-chip application system and the on-board computer fault diagnosis expert system. The single-chip system accomplishes the signal sampling and the data transmission. And the on-board computer expert system adopting the expert system structure widely based on the knowledge and the reasoning rules accomplishes the fault diagnosis. The simulation result proves that the designment of the diagnosis is viable and the on-line fault diagnosis of the locomotive electric transmission circuit can be accomplished.
