摘　　要：对模拟静电场测绘仪进行自动化改进,用单片机控制步进电机实现电压表探针的二维移动,并控制电磁铁进行自动打点记录等势点位置。自动化装置能够确保测量精度,使描绘的电场分布图更准确规范。The electrostatic field simulation instrument is improved for the automatic functions. Stepper motors drive the vohmeter probe two-dimensional mobile controlled by MCU. Furthermore, the electromagnet movement is controlled to record the equipotential points by MCU. Due to the automatic instrument, the measurement accuracy is ensured and the electric filed distribution figure is more accurate standard.
