Research of industrial furnace fault diagnosis expert system

In order to realize fast location and detection of abnormal status during running of industrial furnace, especially abnormal status of firing, this article studies and designs a fault diagnosis expert system based on fault tree theory. Firstly, formalized definition of industrial furnace fault diagnosis expert system is given in the paper, then all component elements of the expert system are analyzed and designed in detail, finally the principles and methods of design knowledge base are introduced to us by using the fault tree theory, and also reasoning algorithm is put forward, which is used to reason the fault by way of fault tree. The project practice indicates that this system knowledge model has good suitability, and what´s more it is used simply and conveniently, also the outcome of fault diagnosis is reliable and steady.
