针对抗血栓压力循环装置的检测需求,设计开发了一套测试系统,并实现了一种压力传感器精度测定的新方法。该方法基于人机交互测试模块,实现了信号多路控制和多路采集功能,并采用线性插值对实验中各测试点进行了多项式拟合,得到了压力传感器的精度系数。结果表明,本测试系统可方便高效地完成对待测压力传感器的精度测试,能有效地校准其参数,使待测压力传感器能准确地用于抗血栓压力循环装置中,推广和应用前景良好。

A new type of testing system used for antithrombotic pressure circulatory equipment has been developed, which realized a new method for the calibration of pressure sensor. Multi-path control and acquisition functions are achieved by this method based on human-computer interaction testing system. The precision of pressure sensor is obrained by polynomial fitting for each test point using linear interpolation method. The result showed that the precision test of pressure sensor could be realized easily and efficiently, using the developed testing system, and the parameters of pressure sensor could be calibrated effectively, so that it could be accurately used in the antithrombotic pressure circulatory equipment. The developed testing system has a prosperous future in the aspects of promotion and application.
