Optical fiber temperature-depth diving mark continuous measuring system

Abstract

The invention relates to marine hydrology parameter monitoring, and particularly discloses an optical fiber temperature-depth diving mark continuous measuring system. The system comprises a communication buoy, a main floating ball, an instrument bin, a demodulating system, a temperature-depth chain, a mooring rope, an acoustical releaser and an anchoring weight, wherein the communication buoy comprises a solar cell, a big dipper communication plate card and a satellite combined antenna; the demodulating system comprises a demodulation module and a lithium battery and is arranged in the instrument bin, and the temperature-depth chain integrates a temperature sensor and a pressure sensor for measuring temperature and pressure, and the communication buoy, the main floating ball, the instrument bin, the temperature-depth chain, the releaser and the anchoring weight are successively connected through the mooring rope. The optical depth diving mark continuous measuring system provided by the invention has the advantages that the high density, real time, continuation and long-term observation of a temperature-depth vertical section from a sea surface to 500m underwater are realized, the data is exact and reliable, and the economic benefit is high; the optical fiber temperature-depth diving mark continuous measuring system is widely applied in different marine observation operations and provides a novel observation means for measuring sea temperature-depth.

Description

technical field [0001] The invention relates to the monitoring of marine hydrological parameters, in particular to a continuous measurement system for optical fiber temperature and depth submersible buoys. Background technique [0002] The high-density, real-time, in-situ, and long-term ocean observation system is to meet the development trend and inevitable requirements of human exploration of the ocean. The 21st century is the century of the ocean. In 2006, the United States made the "establishment of the global ocean observation system" a national science and technology policy; in Asia, Japan took the lead in establishing a submarine earthquake detection station in 1978. They used cables to connect four seismometers sunk into the seabed, which should be It is the embryonic form of the multiple submarine observatories it will establish later. It is driven by various demands that the submarine observation system develops rapidly around the world. China is a big ocean cou...
