Abstract

The invention provides a control method and system for automatic acquisition of a wide-area electromagnetic method, and relates to the technical field of electromagnetic sounding. A wide-area electromagnetic method automatic acquisition control parameter generation device is used for controlling a wide-area electromagnetic transmitting device and a wide-area electromagnetic receiving device to automatically transmit and receive, exploration data are collected, and automatic acquisition and control are completed. The method and the system can be used for ground controllable source detection, intervention of professional instrument operators is not needed during field exploration, the instrument can automatically collect controllable source time domain data needed by exploration, the collection efficiency is high, the working speed is high, exploration constraints are automatically standardized, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electromagnetic sounding, in particular to a control method and system for wide-area electromagnetic automatic acquisition. Background technique [0002] The wide-area electromagnetic method is proposed relative to the traditional controlled source audio frequency magnetotelluric (CSAMT) method and MELOS method. This method inherits the advantages of the CSAMT method using artificial field sources to overcome the randomness of the field sources, and also inherits the advantages of the MELOS method for non-far-area measurement; it abandons the disadvantage of the weak far-area signal of the CSAMT method, expands the scope of observation, and also abandons the The correction method of the MELOS method is adopted, and the high-order terms in the calculation formula are retained; neither the Carnia formula is used nor the non-far area is corrected to the near area, but the apparent resistivity is calculated w...
