Abstract

The invention discloses a multi-channel natural electric field collector which comprises more than two sampling channels and a CPU (Central Processing Unit), wherein the sampling channels are used forcarrying out data collection on a plurality of sampling points at the same time, and the CPU is connected with the sampling channels; the CPU acquires electric field data acquired by more than two sampling channels, performs parallel comparison according to a time sequence, and automatically corrects special abnormal values simultaneously appearing in the more than two sampling channels at the same time point or in the same time period. According to the invention, special abnormal values occurring in two or more sampling channels at the same time point or in the same time period are judged asenvironment abnormal interference and corrected, interference brought by the environment is reduced, and the data accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of geophysical prospecting, in particular to a multi-channel natural electric field collector. Background technique [0002] Geophysical prospecting is referred to as "geophysical prospecting", that is, the method of using physical principles to study geological structures and solve problems in ore prospecting and prospecting. It is based on the differences in the physical properties of various rocks and ores, such as density, magnetism, electricity, elasticity, and radioactivity, to detect changes in natural or artificial geophysical fields, and to obtain geophysical data through analysis and research. Infer and interpret geological structures and mineral distributions. [0003] At present, the main geophysical prospecting methods are: gravity prospecting, magnetic prospecting, electrical prospecting, seismic prospecting, radioactive prospecting and so on. Among them, electrical prospecting is a geophysic...
