摘要
根据伪随机多频激电法的原理及对观测系统的技术要求,设计了WDD型伪随机多功能电法发送机的智能化控制方案,即以MCS 51单片机作为主控单元,编制了可产生多种电流的控制程序;以绝缘栅双极性晶体管(IG BT)作为大功率输出器件,输出最高电压为800V,最大电流为40A,功率可达6kW。试验结果表明仪器性能稳定、安全可靠。
According to the theory of Pseudo-Random Multi-Frequency Induced Polarization method and the technological requirements for the observation system, the authors have designed an intelligent controlling project used in WDD Pseudo-Random Multi-Function Electrical Transmitter. In this project, MCS-51 is used as the main control unit that can produce several kinds of current and IGBT is employed as the high power output unit which can generate maximum voltage 800 v, maximum current 40 A, and maximum power 6 kW. Having used in geological research work in Gansu, Shanxi and Yunnan provinces, the transmitter proves to be stable, secure and reliable.
