Miao Jian · Electric Drive for Locomotives · 2009
According to the requirement of metro train fault detection and diagnosis development,the composition of the onboard fault detection and diagnosis system is introduced. The network architecture of metro train fault detection and diagnosis system based onboard industrial Ethernet is put forward,which network topology structure model is build using network simulation software,and studies its network load,delay the point-to-point key performance of the onboard network as transmission mass failure data and video monitoring information. The simulation results indicate that this simulation model is effective for performance analysis of the onboard fault detection and diagnosis system and can afford objective,reliable quantitative basis for application of industrial Ethernet in metro train.
