摘要
论文介绍了某型光电设备通用自动检测系统硬件和软件的设计 ,详细阐述了系统中采用的数据处理方法。在对检测数据处理中 ,运用小波分析滤除噪声干扰 ,减小了由于干扰而引起的测量误差 ;并针对设备中校准信号比较微弱且频率变动范围已知的特点 ,运用带通滤波器成功地从强噪声中提取了有用信号。
A design scheme of the hardware and software of the general automatic measurement system of a photoelectric equipment are introduced in this paper, and the data processing is also discussed in detail. In order to minimize the error of measurement, method of wavelet analysis is used to eliminate noise in the data processing. Aimed at the feature that the adjusted signal is weak and its change range of frequency is known, band-pass filter is adopted to extract the useful signal preferably from the heavy noise.
