Abstract

In this paper we analyze the relation between fault diagnosis and data fusion

and summarize the correlative techniques of leak detection.In order to make up the shortage of information for leak fault diagnosis

we integrate multi-sensors

such as the dotted sensors and the infrared sensors

to detect the phenomena caused by the leak

and then the system based on data fusion for diagnosing the leak of LRE is established.The approach can enhance the validity and reliability of leak fault diagnosis.
