地质调查中的电法勘探供电系统

THE TRANSMITTER SYSTEM OF ELECTRICAL PROSPECTING METHOD USED IN THE GEOLOGICAL SURVEY

介绍了能用于TEM、IP、p_n法微机控制大功率自动供电系统的工作原理、主要电路的技术特点及在野外实战中的应用。该系统引用了微机实时控制和隔离、光电耦合等先进电子技术,并对抗干扰问题采取了相应措施。在几年来的教学、科研和生产中经受了各种环境和各种恶劣条件的考验,至今从未出现过故障。

The principle of lange power, auto-supply transmiteer system has been introduced in this paper, which can be used in geological survey, by means of electrical prospecting methods.The technique of circuts and the charecters of application of the pystem have also been discussed. The advantages of the system, such as advanced circuts, real - time control of micro-compater, multi-use of one circut, have been proved by three years of field work.
