Ocean temperature depth profile detection system based on combined type high-precision temperature measuring cable

Abstract

The invention belongs to the technical field of ocean temperature depth profile detection, and particularly relates to an ocean temperature depth profile detection system based on a combined type high-precision temperature measuring cable. The ocean temperature depth profile detection system mainly comprises a buoy unit, a temperature measuring cable unit and an anchor system unit which are connected and communicated in sequence, wherein the buoy unit comprises a buoy body and a system control module fixedly arranged in the buoy body; the temperature measuring cable unit is formed by serially connecting a plurality of temperature measuring single sections end to end in sequence; the anchor system unit comprises an anchor body, the anchor body is a metal body comprising a cavity and is sealed, and a power supply module and a battery are arranged in the cavity. The ocean temperature depth profile detection system is based on the buoy technology, adopts the combined type underwater temperature measuring cable, can be flexibly distributed in sea areas at different depths in a single-point or multipoint manner, obtains ocean temperature at different depths according to temperature sensors on the temperature measuring cable at different positions, realizes precise, real-time and long-term monitoring of multipoint and different ocean depth temperature data in specific sea areas, and has the advantages of low cost, easy implementation, high temperature measuring precision and good 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...
