Deep sea current meter with induction transmission communication mode and measurement method thereof

Abstract

The invention relates to the technical field of sea current meters and discloses a deep sea current meter with an induction transmission communication mode. The sea current meter comprises an anchoring object and a buoy body, and is characterized in that the anchoring object and the buoy body are connected through a communication steel cable; and an induction transmission modem is arranged on thebuoy body, and a plurality of induction transmission sea current meters are arranged on the communication steel cable at intervals. The sea current meter can be deployed in a buoy anchor system and asubsurface buoy anchor system, or is integrated in a comprehensive sea observation platform; platform application limitation of a traditional sea current meter is basically removed, data can be uploaded to the platform in real time through the induction transmission module, timeliness and an application value of the data are greatly improved, and problems existing in data storage and access in anapplication of the traditional deep sea current meter are solved. The invention further discloses a measuring method of the deep sea current meter with the induction transmission communication mode.

Description

technical field [0001] The invention relates to the technical field of current meters, in particular to a deep-sea current meter with an inductive transmission communication method and a measurement method thereof. Background technique [0002] The current meter is an instrument for measuring the velocity and direction of seawater flow. It is installed on Argo buoys, anchor data buoys, submersible buoys, seabed bases, autonomous underwater vehicles (AUVs), underwater gliders, survey ships and other ocean current measurement platforms. for ocean current observation. Based on the difference in working principle, traditional current meters can be divided into mechanical current meters, electromagnetic current meters, acoustic Doppler current meters, and acoustic transit time current meters. [0003] The mechanical current meter appeared the earliest among all types of current meters, and it was the main equipment for ocean observation in the past. Due to the problems of conta...

AI Technical Summary

Problems solved by technology

[0008] From the way of use, it is not resistant to high pressure or cannot work in deep water areas. The power consumption is generally high and the working time is short. Generally, it can only be deployed in a single unit, and cannot be used in chains to measure ocean current profiles. There are many restrictions on the platform. Some cannot be applied on ships, some cannot be applied on buoys, and some cannot be applied on submerged buoys; from the actual measurement, it shows that the measurement accuracy and measurement range have certain limitations, are easily affected by the use environment, have general stability, and have blind spots, etc.; from data storage, In terms of transmission and application, only self-contained or read-only can be selected, and it is impossible to receive and process data remotely in real time, and the timeliness and application value of data cannot be further improved
