Underwater subsurface buoy real-time data transmission device and full-profile subsurface buoy adopting same

Abstract

The invention discloses an underwater subsurface buoy real-time data transmission device which is installed on a main floating body of an underwater subsurface buoy and comprises an underwater winch, a lifting platform with positive buoyancy, a profile measurement sensor, a lifting platform controller, a mooring line with positive buoyancy, an acoustic communication unit and a satellite communication machine. The acoustic communication unit is composed of a lifting platform acoustic signal machine and a main floating body acoustic signal machine. The underwater winch and the main floating body audio signal machine are fixedly arranged on the main floating body of the underwater subsurface buoy, and the underwater winch is controlled by the main control computer of the underwater subsurface buoy; the lifting platform audio signal machine, the lifting platform controller, the profile measurement sensor and the satellite communication machine are mounted on the lifting platform; the lifting platform is connected with the underwater winch through a mooring line; and the acoustic communication unit is used for transmitting measurement data and control instructions between the main control computer and the lifting platform controller. According to the invention, ocean full-profile data measurement can be realized, and measurement data can be sent to ground users in time.

Description

technical field [0001] The invention belongs to the technical field of underwater monitoring, in particular to a real-time data transmission device for underwater submerged buoys and a full-section submersible buoy using the device. Background technique [0002] Ocean submersible buoys are the basic means and important technical devices for long-term fixed-point monitoring of the marine environment. Because it is placed underwater, it has the advantages of good concealment and not easy to be destroyed, and is widely used in marine surveys, marine environmental protection, marine development, marine military support and other fields. [0003] Conventional marine submersible buoys are mostly single-point tensioned moorings, and various types of self-contained sensors with different numbers are suspended on the system, and the corresponding technology is relatively mature. However, once the conventional submersible buoy is deployed, it will work underwater for a long time. The...

AI Technical Summary

Problems solved by technology

However, once the conventional submersible buoy is deployed, it will work underwater for a long time. The observed data can only be stored inside the measuring instrument. The data cannot be obtained until the submersible buoy is recovered, and the timeliness of the data will be greatly reduced. In addition, conventional submersible buoys are not easy to access to the waters above the main floating body, and the monitoring of environmental data is less, while the profile environmental data of the upper ocean waters can help people reveal the law of sea-air interaction and influence, which is of more concern to people. Very important for maritime navigation and military activities
