Electric prospecting electrode array borrowing wire remote control

Abstract

The invention relates to an electrical method exploration electrode array circuit remote controller. According to the invention, a signal output by a transmitter remote-control coding module passes through a modulation circuit and a full-bridge power amplifier to output a carrier signal, and a wire corresponding to a terminal of an electric measurement apparatus is arranged at output of the full-bridge power amplifier; a high-frequency channel circuit of a receiver and a switching circuit are connected to A, B, M, and N, the signal output by a full-bridge demodulation circuit is sent to a demultiplexing circuit, the signal output by the demultiplexing circuit is simultaneously sent to a signal shaping circuit and a power supply filter circuit, the signal output by the signal shaping circuit is sent to the remote-control decoding circuit, and voltage output by the power supply filter circuit is the work voltage providing for the circuits. The electrical method exploration electrode array circuit remote controller has the advantages that when an electrical method apparatus is used for measurement, a power supply circuit and a measurement circuit which are necessarily arranged are switched on or cut off through a wired carrier wave remote control receiver, a battery is not required for the receiver, usage is very simple, versatility is strong, remote control distance is far, influence due to topographic relief or barrier obstruction is generated, and remote control reliability is greatly increased.

Description

technical field [0001] The invention relates to the technical field of field electric prospecting, in particular to a remote controller for electric prospecting electrode arrays. Background technique [0002] In the traditional field electrical surveying work, several pole runners carry the wire frame and electrodes on their backs, and under the command of the instrument operator or the walkie-talkie, manually move the electrodes point by point along the measurement line to change the measurement points. This method has been used all the time. So far, its disadvantages are low work efficiency and time-consuming. [0003] After the 1990s, high-density electrical instruments were introduced. It uses distributed electrode switches, and the host uses multi-core cables to switch according to program instructions. Make measurements at a depth of more than 100 meters. In addition, the number of cable cores is large, limited by volume and weight, and the wires in the cable are too...

Problems solved by technology

[0004] The distributed electrode switch of high-density electrical instruments is a closed system. The cables of high-density electrical instruments from different manufacturers cannot be used in common, and this kind of switch cannot be used by traditional instruments.

[0005] In 2010, the inventor applied for a utility model patent of "a wireless remote control of electrode array", the patent number is: 201020616840, this technology uses high-frequency radio waves to control the connection or disconnection of electrodes, although it has achieved certain results , but in areas with severe terrain fluctuations and areas blocked by buildings or trees, the remote control effect will be affected, and most of the prospecting is in mountainous areas, so the application of wireless remote control is very limited

In addition, the dozens of receivers of the wireless remote control all need batteries, and it is very troublesome to check the charging before use, especially at work, if one of the receivers is out of power, the measurement work will be affected
