Description

technical field

[0001] The invention relates to a control system and an operation method of a hand-held pseudo-random transient electromagnetic signal acquisition instrument, belonging to the technical field of geophysical detection instruments. Background technique

[0002] Due to its good practicability and high efficiency, electromagnetic detectors have been widely used in the exploration of oil and gas and coalfield geological structures, the search for metal and non-metallic minerals, hydrological engineering geology, etc., but the existing electromagnetic exploration instruments Due to the large size and complex operation, data calculation and processing cannot be realized at the same time after data collection, so the application is limited, such as the prediction of small-scale geological disasters, the investigation of urban environment and building foundations, and the investigation of underground pipeline laying. , it is necessary to develop a control system of a ...
