Distributed ocean power generation method measuring method and device

Abstract

The invention discloses a distributed ocean power generation method measuring method and device. The distributed ocean power generation method measuring device comprises a generator, an ocean power generation method transmitter, a transmitting electrode, a main receiving node, a plurality of data gathering sub-nodes, a PC upper computer, a software of the PC upper computer, and cables connected between the main node and the sub-nodes, the generator is connected with the ocean power generation method transmitter to input electrical energy to the same, the PC upper computer regulates and controls the voltage, current and frequency generated and sent by the ocean power generation method transmitter, the voltage, current and frequency are transmitted through the transmitting electrode, the PC upper computer sends a command to the main receiving node, the main receiving node controls the data gathering sub-nodes to synchronously gather electrical signals from a receiving electrode, and the gathered digital electrical signals are transmitted to the PC upper computer software through the cables. The distributed ocean power generation method measuring method and device use distributed measurement, the gathering density and precision are improved, and the device is small and light; the cable design and manufacturing technique realize standardization and mass production, the maintainability and reliability of the system are improved, and the expansion performance is better.

Description

technical field [0001] The invention relates to a method and device for ocean electrical surveying, in particular to a measuring method and device for adopting distributed multi-channel synchronous data collection in ocean electrical prospecting. Background technique [0002] Since 1987, the Russian Geological Department has carried out direct current method exploration for oil and sulfide minerals in the ocean, and designed several newest towed systems, which can provide natural potential method (SP) and direct current resistivity method (DC) measurement. Beginning in 1984, Japan conducted several marine electromagnetic (EM) experiments, the largest of which was conducted at the Izu-Bonin arc, and from 1986 to 1992, it was conducted every year around a typical island arc system in the North Western Pacific Submarine EM observations include 17 submarine magnetic surveys (OBM) and 4 submarine electrical surveys (OBE). The Woods Hole Oceanographic Research Institute is also a...

Problems solved by technology

[0004] In order to overcome the shortcomings of existing ocean electrical measuring devices that a single long receiving cable limits the number of acquisition channels and is difficult to repair if damaged, and the number of measurement channels and the distance between receiving electrodes cannot be changed, the purpose of the present invention is to provide a distributed ocean electrical method and device, the method and device can not only solve the problem of mutual restriction between a single long receiving cable and the number of data acquisition channels, but also can easily increase or decrease the number of data acquisition channels and the distance between receiving electrodes, and when the cable is damaged easy to replace
