Abstract:

There are large number of mechanical, electrical and auxiliary devices, and many sensors and intelligent nodes in urban train. The coupling relationship among onboard nodes becomes more and more complex, and various safety detection and information system demand train communication network higher performance. All of these variations need security detection sensor network which has high real-time, bandwidth and interoperability, good maintainability and expansibility. As the existing train communication network transmission rate is low, large capacity status and fault diagnosis data, the event log data, audio and video data which are stored in different vehicles equipments, and cannot be efficient and timely processing. So, it is difficult to realize the information transmission and processing, fault diagnosis and intelligent maintenance of train set. Based on the train level and vehicle level Ethernet network, this paper will focus on network construction technology of large volume onboard security detection sensor network. The research results will help to improve performance of urban train.
