摘　　要： 为实时采集和分析风电机组齿轮箱的振动信号,利用MATLAB与Visual C++(以下简称为VC)混合编程构建了一套实时振动信号采集与分析系统。运用VC编制风电机组齿轮箱的振动信号采集程序,调用MAT-LAB引擎对采集数据进行时域和频域信号处理分析。为测试该系统,对单台风机齿轮箱进行实验测试,测试结果表明,该系统设计合理、运行正常,自功率频谱分析、细化谱分析和小波包分析的结果与齿轮箱运行实际情况吻合。 For collecting and analyzing vibration signals of wind turbine gearbox on rcal time, this paper introduces develop- ment of one set of real-time vibration signal acquisition and analysis system by using MATLAB and Visual C ＋＋ （ thereafter as VC） hybrid programming. The vibration signal acquisition program based on VC applies MATLAB engine to proceed time domain and domain processing analysis on acquisition data. For testing this system, it analyzes experimental testing for single wind turbine gearbox. The testing result shows this system is reasonable in its design and normal in operation. Meanwhile, results including self power spectrum analysis, refining spectrum analysis and wavelet packet analysis are coincided with operation practice of the gearbox.
