The Application of Auxiliary Diagnostic Device in the High Speed Train

Abstract

The paper puts forward a new type electric cabinet auxiliary diagnostic device applied in high speed train. The device mounted in electric cabinet, depending on on-board network, real- time monitoring the status of key electric circuit in electric cabinet. In hardware and software design, the device systematically designs multi-parameter acquisition and decision-making mechanism, in a variety of ways such as hardware acquisition, software calculation, logical configuration, can effectively improve the efficiency of electric fault pre-diagnosis.
