基于BP网络和LabVIEW的推理机设计

Design of an Inference Engine Based on BP Network and LabVIEW

在工程领域中,LabVIEW和MATLAB是程序开发人员最常用的两种语言,但LabVIEW和MATLAB又都有其各自的优缺点,因此将两者结合起来无疑将使程序的开发变得快捷、方便。推理机的设计是故障诊断专家系统设计中的重点和难点,本文基于LabVIEW图形化编程环境和信号分析工具相对完善的优点以及其没有神经网络工具包的缺点,将LabVIEW与MATLAB结合起来设计故障诊断专家系统推理机,并详细介绍了LabVIEW与BP网络相结合的实现方法及其注意事项,使其相互取长补短,具有非常实用的价值。

In field of engineering, LabVIEW and MATLAB is the most commonly used languages in procedure develop personnel. However, they have their respective advantages and disadvantages. Undoubtedly, the combination of the two will wake the develop- ment process faster and convenient for people. Design of inference engine is the key point and the difficulty in the design of fault diagnosis expert system. So the main body of this paper based on the graphical programming environment of LabVIEW and the rela- tively perfect of signal analysis toolkit. It does not have neural networks toolkit, too. The paper, which combines LabVIEW and MAT- LAB to design expert system of fault diagnosis＇ inference engine, have introduced the implementation and attention, making up for one＇s deficiency by learning from others＇ strong points, and it has very pragmatic value.
