摘要
在人工场电磁法勘探中,保持供电电流的稳定是至关重要的。通过对常规稳流技术的分析,提出了一种高精度数字稳流方案,并结合实例阐述了该技术的软硬件设计方法。
In the artificial source electromagnetic exploration, it is important to keep the transmitting current steady. On the basis of analyzing the normal current-regulation technology, the authors put forward a high-precision digital current-regulation technology. An example is also given to illustrate the software and hardware designing method based on the technology.
