Key technology of automatic acquisition system for pseudo-random wide field electromagnetic method
The wide field electromagnetic method(WFEM)has conducted solid theoretical and practical research,but the research on the automation and intelligence of detection equipment is still relatively weak.This paper develops an automatic acquisition system for WFEM.Firstly,the time node control formula for automatic acquisition is derived,and then a set of automatic acquisition parameter structure table and communication control method are designed.Finally,the core algorithm of automatic acquisition and control is realized on the basis of WFEM equipment technology.Experiments show that the WFEM automatic acquisition system can successfully realize automatic acquisition,and the time domain and frequency domain data obtained are in line with expectations.At the same time,it saves 20%in construction time and 71%in human resources.
