基于VB与MATLAB混合编程在钻井泵故障诊断中的应用

Application of Hybrid Programming Based on VB and MATLAB in Drilling Pump Fault Diagnosis

结合MATLAB强大的运算能力和VB的友好界面,详细介绍VB调用MATLAB生成的COM组件在钻井泵故障诊断中的应用过程,提高编程的工作效率。其中钻井泵故障诊断数据处理使用小波分析方法,得出小波分析的能量比和波形分析图形,对钻井泵故障诊断数据处理提供了简便途径。

Combined with the powerful operation ability of MATLAB and friendly interface of VB, the paper introduces in detail the application of COM components generated by VB call MATLAB, improves the efficiency of programming. The drilling pump fault diagnosis data processing uses wavelet analysis method, and draws the energy of wavelet analysis and waveform analysis graph, providing a simple way to the drilling pump fault diagnosis data processing.
