目前汽轮发电机组配备了大量的传感器,如何将各种传感器信息充分利用起来提高诊断准确性是一个很实际的问题。提出了基于多信息融合的汽轮发电机组故障诊断方法,介绍了信息融合的基本概念,给出了基于主观Bayes 方法和基于模型的多传感器融合的实例。关键词:信息融合;故障诊断;传感器Abstract :There are a lot of transducers installed on turbo2generator units. How to use the data sufficiently and to improve the ac2 curacy of fault diagnosis are important problems. Turbo2generator fault diagnosis method based on the information fusion theory is presented in the paper. Information fusion examples based on the Bayes decision method and dynamic model are presented. Con2clusions are given in the end of the paper.Key words :information fusion;fault diagnosis; sensor
