摘　　要：为了高密度电法电极转换操作方便快捷设计了该转换开关,具体设计思路是进行分组模块化设计继电器组,利用中央主控单片机模块控制分组继电器组,达到随时扩充继电器组以扩充电极系长度的目的。在设计中对不同电极进行自动控制,主回路中保持直流供电,两个测量点之间的电压差经过信号处理电路之后进行存储,经通讯接口上传至PC机进行后期数据处理。该设计经室内模拟实验与室外实测该设计达到了实际工作要求。The switch is designed for providing the rapid and convenient operation for the electrode conversion in the high density electrical method. The specific design clue is to design the relay group in the group of modules, and use a central host microcontroller module to control relay group, and to expand the relay group at any time to lengthen the electrode system. Then using SCM controls re- lay and achieves the automatic control of the different electrodes, and remains the main circuit DC power supply and stores the voltage difference between the two measuring points after the signal processing circuit, and uploads via the communication interface to the PC for post data processing. By the indoor and outdoor measurement simulation, it indicates that this design can meet the requirement of the actual survey work.
