摘　　要：信号安全数据网用于实现车站和中继站设备间及其与核心机房信号设备间的安全信息可靠传输。以甬台温铁路车站内列控中心与临时限速服务器通信故障为例,分析组网结构、传输路径,参考网管系统报警信息,快速定位故障点,精准排查安全隐患,满足可维护性指标。Signal safety data network is used to realize reliable safety-critical data transmission between the station and the relay station equipment as well as that between it and core signal equipment room.Taking a case of failure of the communication between the train control center and the TSR server occurring at a station on Ningbo- Taizhou- Wenzhou railway as example,the network structure and transmission path is analyzed. By referring to alarms from the network administration system,the fault point can be located rapidly and potential safety hazard can also be investigated accurately so as to satisfy the requirement of maintainability.
