摘要
介绍了一种测试系统设计与数据分析相结合的方法。设计某光电仪器自动测试系统时，在主控计算机的控制下，通过 ＰＣＬ－８１８Ｌ、 ＰＣＬＤ－７８８和 ＰＣＬＤ－７８５实现了光电信号的采集与控制，并利用小波分析对所采集的信号进行预处理。实验表明，该系统可以完成数据的采集与控制功能，并可以有效地分析强噪声背景下的信号。
A combination method of designing test system and data analyzing is expressed. In the design of the test system for certain photoelectric instrument, PCL-8l8L, PCLD-788 and PCLD-785 realize the acquisition and control of the photoelectric signal under the control of the computer. And wavelet analysis is used to pre-process the acquired signal. The experiment indicates that the system can fulfil the data acquisition and control, and analyze the signals with heavy noise effectively.
