摘要：Recent research and development in the area of next generation train backbones have created an incentive towards the replacement of legacy interconnecting data communication architectures with newer and more innovative backbones. The onboard Ethernet technology has been applied in the train onboard detection sensor network gradually. Network delay is an important factor of detection sensor network quality. This paper analyzes the affection to the network delay of different network topology structure. In addition, the communication network model of onboard detection sensor network based on Ethernet has been constructed by the OPNET Network Modeler. According to the simulation data to analyze the network delay, link load and end-to-end throughput of bus network topology and ring network topology. This will provide technology reference for the onboard detection sensor network and train communication network topology structure optimization.
