Application of Embedded Technology in Transient Electromagnetic Receiver

The transient electromagnetic method (TEM), which is also called time domain electromagnetic method, is one of the common methods of geophysical disciplines of electrical prospecting. This paper, based on theory of the TEM, analysed the application of the embedded technology in TEM, and completed the design of the transient electromagnetic receiver system. The ARM processor is the core part of the system, combined with high precision A/D conversion chip, CPLD module, PC104 and other hardware parts.Through repeated field actual tests, the system works stably and reliably and data acquisition result is favourable.
