| Abstract: | Based on introduction of consist type and TCMS topology of CR200J-3 power concentration EMUs, the problems on the train’s WTB communication at a specific area were discussed, and the corresponding solutions were proposed in this paper. The testing results in practice operation demonstrated that the capability on anti-interference had been obviously improved, while the fault rate was decreased, which would provide an important support for train’s reliable running. |
