Fault diagnosis design for coordinate control system of main coal transport route
-
摘要: 针对主运煤流线协同控制系统存在维护困难的问题,开发了一种主运煤流线协同控制系统故障诊断模块,从设备级诊断、系统级诊断、远程诊断3个方面介绍了系统故障诊断原理:设备级诊断记录相关传感器、本安电源等重要事件并传输给协同控制器;系统级诊断对系统各设备统一授时,由协同控制器运行故障诊断算法分析故障原因,并将分析结果推送至地面集控室;远程诊断是由地面集控室工程师或装备制造企业研发人员分析并确认故障原因,并通知巡检人员排除故障。Abstract: For difficult manual maintenance of coordinate control system of main coal transport route, a fault diagnosis module for the system was developed, and fault diagnosis principle of the system was introduced from aspects of equipment-level diagnosis, system-level diagnosis and remote diagnosis. The equipment-level diagnosis records important events of sensors, intrinsically safe power and so on, and sends the records to coordinate controller of the system. The system-level diagnosis times each equipment in the system uniformity, and adopts the coordinate controller to analyze fault cause through fault diagnosis algorithm and send the analyzed results to centralized control room on the ground. The remote diagnosis is analyzing and confirming fault cause through engineers in the centralized control room or developers in equipment manufacturing enterprise, so as to notify inspectors to remove fault.
