| Abstract: | Zone computer based interlocking is a kind of safety-related signal system to realize the centralized control on adjacent railway stations.The central station can control and supervise the sub-stations collectively by configuring the central station and the sub-stations as a whole system.Safety communication between stations is vital to ensure the safety of the whole zone interlocking system..This paper analyzes the hazards in the communication between stations;puts forward some reasonable safety precautional methods;and describes how to realize the safety-related transmission function to reach a SIL4 safety communication between stations in detail. |
