Abstract

The invention discloses a turbulence signal data processing system and method for an ocean microstructure profiler. The system comprises a first branch, a second branch, a third branch, and a fourth branch, which are respectively used for receiving turbulence transverse data, turbulence longitudinal data, turbulence temperature change data, and turbulence CTD data. The data collected by the turbulence signal data processing system can meet the requirement for ocean turbulence research and analysis, turbulence transverse data, turbulence longitudinal data, turbulence temperature change data and turbulence CTD data are collected by using different branches respectively, interference caused by using the same channel to collect the data can be avoided, and the detection precision is improved. Compared with like systems and methods in the prior art, the system and the method can better cope with adverse factors such as complex environment temperature change, high humidity and high noise for turbulent motion measurement, and has better signal-to-noise ratio performance, smaller size and lower power consumption. The method and the system are widely applied to the technical field of electronic circuits.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a turbulence signal data processing system and method for an ocean microstructure profiler. Background technique [0002] Turbulent motion is the main form of kinetic energy dissipation in the ocean. The mixing process of ocean turbulence is a micro-scale "random" movement that occurs in the ocean. Turbulent kinetic energy dissipation is an important parameter for understanding ocean turbulence. Ocean turbulence plays an important role in understanding how ocean circulation moves, transporting energy and matter in ocean water, and improving global climate models. The ocean microstructure profiler is an important tool for observing ocean microstructure turbulence. The ocean microstructure profiler can collect electronic data related to turbulent movement, so as to analyze the turbulent movement by computer. [0003] The current turbulence signal acquisition and proces...
