Study On The Real-time Monitoring System Of Marine Hydrology Based On The Beidou Satellite System

Marine science and technology is currently one of the five strategic areas for China's advanced deployment.Ocean observation is the foundation of marine science and technology.The real-time monitoring of ocean hydrology is an important part of the ocean observation network.This paper is based on the real-time monitoring system of the marine hydrological Beidou satellite system,for monitoring ocean hydrological data problems,put forward to the ocean buoy platform,equipped with CTD by pairs of sensors and data acquisition and processing module,realize the cloth in temperature,salt,profile,long-term real-time monitoring;for real-time data transmission and real-time control the buoy system,the Beidou satellite data communication link,through compression and transmission protocol design study on data transmission,realize data acquisition and real-time transmission control and buoy work state monitoring and remote control;to solve the problem of data communication and storage and system management and monitoring,puts forward the design of monitoring station through the study of the shore station unit,monitoring unit of software and hardware,realizes data transmission and storage system,the order of the tube Daniel.In this paper,the overall design of the system is carried out according to the requirements analysis and research objectives of the system.The overall structure of the system is divided into buoy unit and bank station monitoring unit.The buoy unit includes sensors,data acquisition and data processing module,the monitoring unit including shore shore station monitoring center and remote control buoy monitoring system;secondly,the buoy unit design mainly includes the data acquisition system and the buoy body part two.The data acquisition system is composed of the acquisition main control service module,the acquisition array terminal,the acquisition system cable array and the Beidou communication terminal.Buoy body mainly completed the standard design and structure design index analysis;then,base unit design mainly includes the base unit of hardware system and software system base unit.The hardware system is mainly composed of the database server,the data acquisition terminal and the Beidou communication terminal.Base unit of software system mainly includes base unit software system architecture,function,function modules,database tables,each function module design;finally,the system test mainly includes functional modules and test the whole system debugging test,test the whole system from the correctness and reliability of the collected data of the whole process.The real-time monitoring system of marine hydrology based on Beidou satellite system development,telemetry and monitoring of buoy system by shore center station,central station to obtain real-time hydrological data from buoys,after processing the data provided to the database and the application system interface,provides scientific data and strong support for the development of the ocean marine observation and technical equipment.
