摘　　要：本文设计一种三维并行直流电法勘探系统:LQC-II型三维电阻率采集系统,由主机、电测子站和多模式智能电极三部分组成。主机控制电测子站完成16通道、24位数据电性数据的并行采集与传输,每个电测子站控制与之相连的16个电极的同步与状态转换。以1台主机控制16个电测子站和256个智能电极对水池低阻体模型进行电极扫描式测量,获取32640个数据的测量为例,整个测量时间约30分钟。A new 3D electrical prospecting system （LQC-II 3D resistivity data acquisition system） was designed in this paper. It was composed with the host, electricity sub-stations and multi-mode intelligent measurement elec trode. The 16-channel, 24-bit data parallel electrical data acquisition and transmission of every electricity sub-sta- tion was controlled by the host . Synchronization of 16 electrodes and state transitions was controlled by attached the electricity sub-stations. For example, it acquired 32,640 data measurement that one host controlled 16 meas-uring stations and 256 intelligent electrodes with electrode scanning measurement mode in pool of low resistivity model, and it needed about only 30 minutes.
