摘　　要：依托工程实践的CDIO工程教育模式可以高效培养学生的综合实践和创新能力。为夯实工程实践学习资源,综合传感器原理应用、信号调理电路、电机控制、单片机技术等课程设计了一套基于电容式位移传感器的平面定位控制系统。该平面定位控制系统采用自制的PCB平板电容和信号调理电路实现平面双轴丝杠的位移传感器功能,采用DRV8412实现两路直流电机的全桥驱动,实现工作探头的快速精确定位和多种扫描方式的平面运动。The CDIO engineering education mode based on engineering practice can effectively cultivate students’comprehensive practice and innovation ability.In order to consolidate engineering practice learning resources,a planar positioning control system based on capacitive displacement sensor is designed.The planar positioning control system adopts the self-made PCB plate capacitance and signal conditioning circuit to realize the displacement sensor function of the planar biaxial lead screw,and uses DRV8412 to realize the full-bridge drive of the two-way dc motor,so as to realize the quick and accurate positioning of the working probe and the planar movement of various scanning modes.
