Power saving circuit of exploring tube

Abstract

The invention provides a power saving circuit of an exploring tube. The power saving circuit comprises a transformer, a reverse excitation circuit, an SHDN enabling module, a single chip microcomputer and a detection pulse module; the input end of the detection pulse module is connected with a pulser, the output end of the detection pulse module is connected with the input end of the single chip microcomputer, the output end of the single chip microcomputer is connected with the input end of the SHDN enabling module, the output end of the SHDN enabling module is connected with the input end of the reverse excitation circuit, and the output end of the reverse excitation circuit is connected with the input end of the transformer through a MOS transistor; the SHDN enabling module is connected with the power supplying enabling end of a directional sensor; the transformer is connected with the power supply end of the directional sensor. According to the power saving circuit of the exploring tube, power supplying of the directional sensor is intermittent power supplying, power supplying is reduced after valid data is collected, energy sources are saved, and the power quantity can be saved by 50% or above through approximate calculation according to the duty ratio.

Description

technical field [0001] The invention relates to the technical field of downhole detection equipment, in particular to a power-saving circuit for a probe tube. Background technique [0002] Now, well logging instruments are often used in geological exploration and drilling processes such as hydrology, engineering, coal fields, and metal mines. This logging instrument includes two parts: a well logging host and a well logging probe. The probe detects and collects signals underground, and then the logging host displays the signal data, translates it into the required first-hand geological data, and then performs follow-up drilling work based on the obtained data. plays a key role. At present, most of the logging instruments in our country use logging probes to go downhole to collect signals, and use uninterrupted power supply, which consumes a lot of power and is not energy-saving and environmentally friendly. [0003] For example, the utility model patent of Chinese Patent P...
