Abstract

This invention discloses one electrical exploring signal receiver and its amplifying intelligent control method, wherein, the receiver comprises two degrees of amplifiers and filters, A / D converter and computer system, wherein, each amplifier output end, filter output end are connected to input end of one selector with output end and second filter output ends and amplifier output end connected toother selector switch input end; the other selector switch output end is connected to input end of A / d converter.

Description

technical field [0001] The invention relates to an electrical prospecting signal receiver and an intelligent control method for its amplification factor. Background technique [0002] In electrical prospecting, the amplitude of the signal collected by the electrical prospecting signal receiver (hereinafter referred to as "electrical prospecting receiver") varies widely. The amplitude of the smallest signal is less than 10uV, and the amplitude of the largest signal can exceed 10V. This requires the receiver to have multi-level and multi-block amplification factors, which can effectively amplify various signals. For example, the GDP-32II multifunctional electrical prospecting receiver produced by ZONGE Company of the United States adopts a one-stage attenuation and three-stage amplifying circuit. The first level of magnification is 1, 4 and 16 three gears. The step difference between the second stage and the third stage magnification is 2, and each stage amplifier has 7 sta...
