接口信息一致性诊断在信号集中监测系统中应用

Application of Consistency-based Diagnosis of Interface Data in Centralize Signal Monitoring

信号集中监测系统汇集了列控和ZPW-2000等接口子系统的数据信息,通过开发信息一致性逻辑诊断功能,可实现这2个接口子系统信息的校核。本文重点介绍一致性诊断机制模型、软件诊断的推理机制和处理流程,并结合列控和ZPW-2000接口子系统的数据源进行了试验仿真,仿真结果满足设计需求,且当接口信息不一致时,能及时给出报警,可预防故障发生。

The centralized signal monitoring system collects the data from the train control system and the ZPW-2000 system.By developing logic function of data consistency diagnosis,the centralized signal monitoring system can realize data check of the two systems.The consistency-based diagnosis mechanism model,reasoning mechanism and processing flow of software diagnosis are highlighted.In combination with the data sources of the train control system and the ZPW-2000 system,a simulation test has been made.The simulation results show the design require-ments can be met.When the interface data is inconsistent,early warning can be send off quickly and the purpose of preventing failure can be achieved.
