摘　　要：为了提高压缩机性能测试数据采集的精度和使用灵活性,采用ActiveX技术对数据采集模块进行封装。运用最优化分段最小二乘法对传感器进行线性化处理,通过中位值平均软件滤波法消除由于脉冲干扰等因素所引起的采样值偏差。采用该数据采集模块控件,能快速完成压缩机性能测试数据采集的软件编写,还可以提高采样的灵活性和准确性。In order to improve the precision and facility of the data acquisition on refrigeration compressor performance test, it＇s a better way to encapsulate based on ActiveX technique. Using least squares method and optinazation piecewise-linear algo-rithm to linear treatment of the sensor, by median and mean filter algorithm to eliminate the offset of sampling values caused by pulse interference. Adopting this data acquisition module encapsulation can quickly design the software, and increase signal acquisition precision and facility.
