传感器故障诊断中的数据关联方法与应用

摘要

基于信息融合技术中的数据关联技术，提出了将数据关联方法用于故障监测、报警的问题，改进了多传感器多模型相互作用的概率数据互联算法，结合某时变系统中传感器的故障诊断问题，进行了仿真分析，并讨论了这种方法在故障报警和预测预报中的应用。%Based on the data association of information fusion, the problem of applying data association method in fault detection and/or alarming is promoted. The algorithm of multi-sensor multi-model inter-action probability data association is improved. According a time varying system's sensor fault, simulation result is given. The application of the method in the fault detection and/or alarming is discussed.
