传感器故障诊断实时监测系统设计的探讨

对大型设备运行状态监测和故障的早期诊断与预报活动中，传感器自身故障的及时发现与判别尤为重要。本文提出以设备子系统的（或某一功能的）传感器监测参数为划分原则，将单传感器的监测信号综合作为多传感器监测而进行信息的融合处理，从而判别子系统运行状态和传感器信号的真实性的构思，并探讨传感器故障诊断实时监测系统的设计方案。

DESIGN OF SENSOR'S FAULT DIAGNOSIS AND REAL-TIME MONITORING SYSTEM

For large equipment, it is important that a fault of sensor self can be find out in time during an operating monitor and early diagnosis and prediction. This paper propose an idea that grouped all sensors (installed on the equipment or sub system of equipment) according to the principle of the type monitoring parameters from a sub system or certain function of equipment, the information from these individual sensors can be treated by the data fusion theory as a multi sensor system, and one can distinguish the reality of sensor's and the condition of equipment. A scheme of the real time monitoring system for sensor self fault diagnosis is discussed.
