接口信息一致性诊断在信号集中监测系统中应用
|
摘要
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 consistencybased 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 requirements 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.
