| Abstract: | For the problem of delay and missing of the data exchanged periodically between stations in Qinghai-Tibet Railway(QTR),a method of data toleration analysis is proposed,which can ensure the safety and enhance the availability of the systems.The contents of the data exchanged between stations in QTR as well as the toleration setting of different data are described and a solution in which one RBC device is used to manage multiple stations is proposed. |
