| 摘 要： | 讨论了一种基于 MCA770 7的智能传感器补偿系统。该系统可以补偿传感器 (特别是硅压阻传感器 )温度误差的线性部分和高阶非线性部分。通过该芯片的补偿 ,可以使硅压阻式传感器的重复性误差小于 0 .2 %。该系统能够自动地记录和计算各项补偿系数 ,从而大大地简化了补偿的工作量。为了方便操作 ,系统还设计了向导式的工作界面。

| Abstract: | This paper presents a smart compensation system based on MCA7707 (a kind of signal processor). The linear errors and high order errors of a sensor (especially piezoresistive sensor) can be corrected by using this system. It can optimize the process of piezoresistive sensor calibration and compensation, then, a total error factor within 0.2% of the sensor′s repeatability errors is obtained. Data are recorded and coefficients are determined automatically by this system, thus, the sensor compensation is simplified greatly. For operating easily, a wizard compensation program is designed to correct every error and to get the optimum compensation. |
