Research on Harmonic Interference Around BTM Antenna of CR300BF EMU.

The reason of the interference problem of BTM system is that it is greatly affected by the external environment and car body working conditions in the process of failure, and it is difficult to find after the fault occurs, and the means are limited, so it is impossible to formulate effective rectification measures. Through analyzing the new CR300BF EMU BTM system fault phenomenon, this paper mainly studies the fault investigation, determination, treatment and summary, finally finds out the cause of the fault after many processing and research, and formulates effective measures, which provides ideas and methods for the acceptance, maintenance and fault treatment of the onboard train control equipment of similar models in the future.
