摘要
针对目前牵引变电自动化系统(TSAS)总线式通信网络存在的问题,提出一种分布交换式通信网络。应用故障树分析法建立通信网络的失效模型,计算失效参数和可靠度,得出分布交换式网络结构的可靠性高于总线式网络的结论。
To deal with the weakness of current field - bus communication network of Traction Substation Automatic System （TSAS） , a new distributed and exchanged Ethernet network communication system was brought forward. Using Fault Tree analysis method, the failure model of the new network was established. Failure parameters and reliability of the Distributed and Exchanged network was computed. It was concluded that the reliability of distributed-exchanged - type network is better than field bus-type network.
