Disposable optical fiber temperature and depth instrument measuring system

Abstract

The invention provides a disposable optical fiber temperature and depth instrument measuring system. The system comprises one or more disposable optical fiber temperature and depth probes and an optical information demodulation and control system. The disposable optical fiber temperature and depth probes are used for reflecting optical signals output by the optical information demodulation and control system and sending the reflected optical signals to the optical information demodulation and control system through optical fibers; and the optical information demodulation and control system outputs the optical signals, detects a wavelength of the reflected optical signal of each disposable optical fiber temperature and depth probe, and solves a physical quantity of a position of the corresponding disposable optical fiber temperature and depth probe based on the wavelength. In the invention, a measurement depth, precision and reliability of domestic underway temperature and depth measurement equipment can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of ocean observation equipment, and in particular relates to a throw-away optical fiber thermometer measuring system. Background technique [0002] The 21st century is called "the century of the ocean". The status of the ocean will become more and more important in the survival and development of human beings. Ocean development has become an important priority for any nation-state with ocean resources to establish a national development strategy. The most important. Marine environmental survey is the basis and premise of marine development. Marine hydrological survey is the most basic content of marine environmental survey, mainly including temperature, salinity, density, sound velocity, ocean current and other important marine environmental parameters. It is an important content of marine three-dimensional monitoring , Obtaining and studying these parameter information is the premise of mastering the law o...
