An intelligent cable and measurement method for high-density electrical measurement system

Abstract

The invention discloses an intelligent cable for a high density electrical measurement system and a measurement method. The intelligent cable is characterized by comprising an A core wire, a B core wire, an M core wire and an N core wire; the A core wire and the B core wire are respectively connected with the positive electrode and the negative electrode of a high-pressure transmitting terminal of a host computer; the M core wire and the N core wire are respectively connected with a voltmeter of the host computer; the A core wire, the B core wire, the M core wire and the N core wire are all divided into two disconnected sections to be arranged at two ends of a connection box; the A core wire, the B core wire, the M core wire and the N core wire are respectively provided with linked switches which can be communicated with the same core wires; a grounding sheet metal connected with a grounding electrode is arranged in the connection box; one section of each of the A core wire, the B core wire, the M core wire and the N core wire can be connected with the grounding sheet metal through the corresponding connection switch; a signal receiver connected with the host computer and used for controlling the connection switches is arranged in the connection box. The quantity of the core wires in a cable is reduced to four, the quantity of the core wires is reduced, the weight of the cable is reduced, and the working efficiency can be improved greatly.

Description

technical field [0001] The invention relates to an intelligent cable and a measuring method for a high-density electrical measuring system. Background technique [0002] Currently used high-density electrical prospecting instruments such as DUK-2A and DUK-2B high-density electrical prospecting instruments produced by Chongqing Geological Instrument Factory, and SuperSting R1 / IP and SuperSting R8 / IP produced by American AGI Company are equipped with All cables are composed of multiple core wires (more than four), but only 4 core wires (power supply wires A and B and measurement wires M and N) are required in the actual measurement process. It can be seen that the cables used in the traditional high-density electrical measurement system waste materials on the one hand, and on the other hand, due to the large number of core wires, the weight of the cable itself is relatively large, which is clumsy and inconvenient to carry during field exploration. It is inconvenient to take i...

It can be seen that the cables used in the traditional high-density electrical measurement system waste materials on the one hand, and on the other hand, due to the large number of core wires, the weight of the cable itself is relatively large, which is clumsy and inconvenient to carry during field exploration. It is inconvenient to take in and out the wire, and it is time-consuming and labor-intensive in the application process, which seriously affects the work efficiency
