Design of an Inference Engine Based on BP Network and LabVIEW

In the field of engineering, LabVIEW and MATLAB are the languages most commonly used by program developers. Howev-er, they have their respective advantages and disadvantages. The combination of the two will undoubtedly facilitate program develop-ment. Design of inference engine is the key point and difficulty in the design of fault diagnosis expert system. This paper combinesLabVIEW and MATLAB to design the inference engine of fault diagnosis expert system based on the advantages of the graphical pro-gramming environment and signal analysis toolkit of LabVIEW without the defect of neural network toolkit. In addition, it introducesthe implementation methods and precautions for combination of LabVIEW and BP network so as to make LabVIWE amd BP benefitfrom each other, which is of great pragmatic value.
