High-density electrical exploration transmitter

Abstract

The invention relates to a high-density electrical exploration transmitter. A data processor is respectively connected with a lead A, a lead B and transmitting voltage sampling circuits through a transmitting circuit power supply electrode interface A and a transmitting circuit power supply electrode interface B of a master control circuit. The transmitting voltage sampling circuits are connected with the high-density electrical exploration transmitter, the master control circuit is connected with a distributed high-density slave machine interface through a grounding resistance measurement switching circuit, and the master control circuit is connected with the high-density electrical exploration transmitter through the distributed high-density slave machine interface, thereby achieving measurement by means of various user-defined exploration methods in a large range under the condition that the number of slave machines is few. A transmitting circuit can transmit user-defined coding wave forms consisting of any 1, 0 and -1 and coding wave forms generated by system random functions so as to achieve geological exploration by selecting appropriate coding wave forms at an exploration scene.

Description

Technical field: [0001] The invention relates to an electrical instrument for geophysical prospecting, in particular to a launcher for high-density electrical prospecting. Background technique: [0002] High-density electrical measurement is a widely used electrical prospecting instrument at present. Because this method completes the entire measurement process under program control, and the electrode distance is small, the final quasi-earth electrical profile has high resolution and is practical. stronger. Its use is mainly used for near-surface electrical prospecting to solve engineering geological problems such as rammed earth dam body disease detection, deep sink detection in old mining areas, geological safety assessment of industrial buildings, and search for groundwater. However, in our application practice in recent years, we have also clearly felt its shortcomings: first, it has poor anti-interference ability for weak signals from deep underground, especially when u...

Problems solved by technology

However, in our application practice in recent years, we have also clearly felt its shortcomings: first, it has poor anti-interference ability for weak signals from deep underground, especially when using the Schellenberg method.

However, this invention only describes the generation of waveforms, but does not involve the connection with the transmitter, and does not have the function of real-time monitoring of the generated encoded signal waveforms
