Underwater data wireless transmission subsurface buoy

Abstract

The invention relates to an underwater data wireless transmission subsurface buoy, and belongs to the technical field of marine environment information monitoring. The underwater data wireless transmission subsurface buoy comprises a hydrophone, a water passing machine, an electronic cabin, a releaser, a floating ball, a buoy body frame and a base, the hydrophone is fixedly arranged at the upper part of the buoy body frame; the water dredging machine is fixedly mounted at the upper part of the buoy body frame; the electronic cabin is mounted at the lower part of the buoy body frame; the releaser is mounted on the buoy body frame, is connected with the base and can release the base; and the floating ball is fixed above the buoy body frame. The subsurface buoy is provided with the water passing machine, real-time transmission of underwater data can be achieved, and the subsurface buoy is not prone to being exposed underwater during data transmission, has concealment and is not prone to being lost. The subsurface buoy carries out data processing on original data, the data size of result data is greatly reduced compared with that of the original data, and underwater data transmission is facilitated. The subsurface buoy is small in size and light in weight, does not need heavy hoisting equipment, does not need an additional anchoring device, and is easy and convenient to lay and recover.

Description

technical field [0001] The invention relates to a submersible buoy for wireless transmission of underwater data, which belongs to the technical field of marine environment information monitoring. Background technique [0002] The acoustic submersible buoy system is an effective means of obtaining marine environmental information. It can work underwater for a long time, continuously and covertly under harsh marine environmental conditions. Information is collected. In the 1960s, some marine developed countries began to use submersible buoys, and rapidly developed their own submersible buoy technology on this basis. After decades of development, the submersible system has become one of the important means of investigating the marine environment. The submersible system does not require personnel to control it, can work in most marine environments, has a long working cycle, and has good concealment. It can automatically detect marine meteorology in real time. At the same time...

Problems solved by technology

If there is a problem with the acquisition system, the submerged mark data may not be available, which will consume a lot of manpower and material resources

[0004] The patent with the publication number CN112367112A discloses a real-time data transmission system for deep-sea submersible buoys based on a multi-mode satellite communication system. It uses a satellite communication system for real-time data transmission, but the equipment needs to be exposed above the water surface when sending data through satellites. It is easy to be salvaged and cause loss, and the data transmission is original data with a large amount of data. In the case of limited transmission data bandwidth, the data transmission time is relatively long

The patent with the publication number CN112478059A discloses a marine submersible buoy system device based on multi-element measurement. It has a complex structure, large size, and heavy weight. It requires the test ship to be equipped with heavy equipment such as cranes and winches for deployment and recovery. Recycling brings large manpower and material costs
