Abstract

The invention discloses a sea ice monitoring system and a monitoring method. The system comprises a laser emission system, a laser fluorescence receiving system, a photoelectric conversion system, a signal acquisition system and a control system, wherein the laser emission system is used for emitting laser which is high in power and relatively high in repetition frequency and having a special wavelength to a sea surface; the laser fluorescence receiving system is used for collecting a fluorescence signal from stimulated emission of sea ice, and transmitting the received fluorescence signal to the photoelectric conversion system; the signal acquisition system is used for converting an analog electrical signal into a digital signal and storing the digital signal in the control system; the control system is used for implementing data analysis, processing, comparison and display through a data analysis processing system. The monitoring system and the monitoring method disclosed by the invention can make use of sea ice stimulated fluorescence spectrum databases at different temperatures, and analyze and compare the databases through a computer, so as to efficiently and accurately resolve existence of the sea ice; the monitoring system and method, through determining attenuation degree of fluorescence signal strength in the sea ice, can accurately reflect thickness of the sea ice.

Description

technical field [0001] The invention belongs to the technical field of marine environment detection, and in particular relates to a sea ice monitoring system and a working method thereof. Background technique [0002] As a member of the global sea-atmosphere system, sea ice interacts with ocean and atmospheric circulation and affects human activities such as maritime transportation, marine fisheries, and marine oil and gas resource development. Sea ice can not only block port channels and interrupt maritime transportation, but also damage port engineering facilities and various offshore installations. In addition, when the ice condition is severe, it will also affect fishery production activities. The drift of sea ice will also cause huge damage to offshore oil and gas exploration and production. hazards. [0003] At present, sea ice monitoring means mainly include: on-site personnel observation, long-term ice station observation and satellite remote sensing observation. On...
