摘　　要：以MAXIM公司的MAX1457为核心,设计开发出了硅压阻式传感器的智能误差补偿系统。该系统由硬件和软件两部分组成,主要解决了硅压阻式传感器的一致性、温度漂移和非线性等问题,使它的输出精度达到了0.2%以内。同时给出了误差补偿系统的总体方案、信号调理电路的设计技术和MAX1457补偿系统软件的设计与实现。The smart error compensation system is designed with MAX1457 as its core. The issues of consistency, temperature shift and non - linearity are solved by the system which is composed of hardware and software. An output error factor of silicon piezoresistive sensor is achieved within 0.2%. The main contents to be studied and solved are shown as follows：designing scheme of the error compensation system, studying and designing the signal conditioning circuit, designing and realizing the MAX1457 software development system.
