Abstract

The invention belongs to the technical field of ocean temperature and depth profile detection, and in particular relates to an ocean temperature and depth profile detection system based on a combined high-precision temperature measuring cable. The system mainly includes a buoy unit, a temperature measurement cable unit and a mooring unit connected in sequence; the buoy unit includes a buoy body and a system control module fixed in the buoy body; Composition; the anchoring unit includes an anchor body, the anchor body is a metal body with a cavity and is sealed, and a power module and a battery are arranged in the cavity. The system of the present invention is based on the buoy technology, and adopts a combined underwater temperature measuring cable, which can be flexibly and maneuverably deployed in various sea areas at different depths, and the temperature sensors at different positions on the temperature measuring cable can obtain the temperature of different depths. Ocean temperature realizes accurate, real-time and long-term monitoring of temperature data of multiple points and different sea depths in specific sea areas. It is low in cost, easy to implement, high in temperature measurement accuracy and good in reliability.

Description

technical field [0001] The invention belongs to the technical field of ocean temperature and depth profile detection, and in particular relates to an ocean temperature and depth profile detection system based on a combined high-precision temperature measuring cable. Background technique [0002] Acoustic waves are currently the only effective means for long-distance marine resource exploration and target detection. The main factors affecting the propagation of sound waves are seawater temperature, salinity and pressure (depth), etc., among which the change of temperature has the greatest influence on the speed of sound. Due to the uneven distribution of temperature and salinity in the seawater medium, the uneven distribution of sound velocity will be caused, thereby forming the sound velocity gradient in the ocean, which will affect the accuracy of various sound measurement equipment. Therefore, underwater temperature and depth profile data have very important military valu...
