| description | The invention relates to an online-state-monitoring-based equipment reliability evaluation method for a decentralized control system. The method for evaluating all pieces of equipment in a decentralized control comprises: step one, carrying out online monitoring on a to-be-evaluated device; step two, acquiring fault information of the device during a monitoring period; step three, calculating an average fault-free time interval of the device; and step four, determining the operation reliability of the device based on the average fault-free time interval. Compared with the prior art, the evaluation result is objective and reliable and can reflect the state of the device in real time; and the reference value is high.
本发明涉及种基于在线状态监测的分散控制系统设备可靠性评估方法，该方法对分散控制系统中的各个设备分别进行评估，具体为：(1)对待评估的设备进行在线监测；(2)获取该设备在监测时段中的故障信息；(3)求取该设备平均无故障时间间隔；(4)根据平均无故障时间间隔确定该设备运行可靠性。与现有技术相比，本发明评估结果客观可靠，能够实时反应设备状态，参考价值高。 |
