| 摘 要： | 为实现对某自动检测系统信号的实时检测，本文以工控机和数据采集卡PCL-1713为硬件平台，VC＋＋为软件平台，利用DAQ控件和动态链接库两种方法，分别对电压信号进行采集。针对数据采集中误差出现的随机性，采用数字滤波对采集信号结果进行处理，并利用非线形校正法，以MATLAB为工具，对信号进行拟合校正，测试精度达到0．003V，满足数据采集的要求。与以前同类数据采集系统相比，改进了测试流程，提高了测试效率，信号的采集更加快速，准确。此采集系统现已应用于某装备自动检测系统。

| Abstract: | For the signal real-time acquisition of a automatic testing system,which is based on industrial computer and PCL-1713 analog input card and Microsoft Visual C++(VC++)developing platform,the voltage signal acquisition is realized in two ways:DAQ control and dynamic link library(DLL)that are provided by ADVANTECH.Inc.Digital filter is adopted in data processing to deal with the randomicity of data's error.Data non-linear fitting in least-square is done in MATLAB that indicates that testing precision achieves ... |
