Probe Power Saving Circuit

Abstract

The present invention proposes a probe tube power-saving circuit, comprising: a transformer, a flyback circuit, an SHDN enabling module, a single-chip microcomputer, and a detection pulse module; the input end of the detection pulse module is connected to a pulser, and the output end thereof is connected to the The input end of the single-chip microcomputer, the output end of the single-chip microcomputer is connected to the input end of the SHDN enabling module, the output end of the SHDN enabling module is connected to the input end of the flyback circuit, and the output of the flyback circuit is The terminal is connected to the input terminal of the transformer through a MOS tube; the SHDN enabling module is connected to the enabling terminal of the orientation sensor power supply; the transformer is connected to the power supply terminal of the orientation sensor. The invention makes the power supply of the directional sensor intermittent, and after valid data is collected, the power supply is lowered to save energy, and more than 50% of electricity can be saved according to the approximate calculation of the duty cycle.

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...
