Research And Design Of Data Acquisition System For Marine Environment

Marine environmental data collection is a collection of temperature and humidity,flow velocity,flow direction,wind speed and wind direction of ocean environment data.These data can make us better understand the ocean,monitor the ocean,develop the ocean,and be able to play a positive role in the transportation and transportation areas such as navigation support and channel optimization.Therefore,the research and design of marine environmental data acquisition system is of great significance.This dissertation relies on the sea island group of biological resources and environmental monitoring and equipment technology demonstration projects for development(201505025-6).First introduces the background and significance of the marine environment acquisition system,and makes a simple description of the domestic and foreign development situation,and then analyzes the overall structure of the marine environmental data acquisition system design,and introduce some related technologies.Finally,the software and hardware design and development of the acquisition system is completed.After operation test,the acquisition system can achieve the desired goal.The marine environment data acquisition system designed in this dissertation is the core of the main control board and the driving board with two different series of STM32 microprocessors.Both of them communicate through the CAN bus.The main control board controls the GPRS communication module to maintain the remote communication and data transmission of the data acquisition terminal and the remote monitoring center,and the drive board is responsible for driving a variety of sensors to collect related hydrometeorological data.In the hardware part,the circuit design of the data acquisition terminal is mainly designed,including the hardware basic circuit of the main chip,the data acquisition circuit,the GPS positioning module and the GPRS wireless communication module.The software part mainly develops the embedded program for the main control board and the drive board of the terminal,including the GPRS communication code,the GPS positioning code and the CAN bus program development.The terminal is connected with the remote monitoring center,realize data acquisition and remote control information on data acquisition terminal.At last,the dissertation tests the operation of marine environmental data acquisition system,and points out the shortcomings in the development,and puts forward the improvement measures and suggestions.This design provides an efficient solution for collecting marine environmental data,and provides a new way for observing all kinds of marine elements.
