Research On Intelligent Observation Solution For Marine Water Quality Based On Internet Of Things

In recent years,with the development and utilization of the oceans,marine environmental pollution gradually intensified,the ecological environment has been seriously damaged,in order to effectively develop and use marine resources,protect the marine environment ecology,promote marine scientific research and accelerate marine economic development,marine ecological environment monitoring and protection is imperative.Among them,water quality monitoring is one of the important ways of marine ecological monitoring,with the development of application needs and science and technology,water quality monitoring applications more widely.Guided by the basic theory of ocean monitoring,this paper presents the research topic“intelligent ocean water quality observation solution based on the Internet of things”from the current situation of ocean observation,the actual needs and the development of Internet of things technology,wireless communication technology and computer software technology are concluded.In order to build a practical ocean monitoring system as the research goal,taking into account different hardware platforms,sensor technology,wireless communication technology and communication protocols and software technology,we designed a fixed-point observation program framework and ship-based observation program framework for the SEA scene range,as a solution to achieve intelligent monitoring of the marine environment.The program provides new ideas to achieve the goal of ocean monitoring observation data integration,monitoring system structure,real-time data transmission,collection and analysis integration.In order to verify the feasibility and reliability of the design scheme,this paper selects the near-shore observation scenario under the fixed point scenario,designs a near-shore water quality monitoring system which integrates communication network,early warning intelligence,system modularity and high transmission in real time,introduces the overall design goal.The overall composition structure and the functions of each module is made.Then the system hardware selection and system software is under implementation,and finally the system function will go through test and stability test.This thesis mainly completed the following 2 parts of the work:First,this paper designed a fixed point observation program framework and shipbased observation program framework.As the realization of regional unified monitoring of Marine intelligence information and publishing platform is carried out,so that data monitoring and Information Services Integration,Data Acquisition,data processing,data routing transmission,data analysis,real-time display and regional data sharing and other functions are integrated in one,which carried out the formation of a complete and practical system to improve the level of ocean monitoring and management.Second,through the overall structure of the system division,system functional modules and hardware selection and software design and development,to achieve a near-shore water quality monitoring system,the system has the following functional modules:(1)Acquisition module,the acquisition module is responsible for real-time water quality data collection and automatic transmission,but also two-way communication,not only can transmit hydrological water quality data,you can also receive instructions.(2)Transmission module,transmission module is actually a bridge between the observation point and the Monitoring Center data transmission,communication between the two sides to achieve synchronization of observation and command data.(3)Processing module,data processing module automatically processes the received data,processed into the database as a display of the data source,while the processing center will be judged according to the quality of the sensor data read into the log file,recording data quality and equipment working status.(4)Display module,data display module is the observation data in real-time display,dynamic monitoring of observation data,real-time data for dynamic chart display and display,real-time warning of mutation data,Historical Data Query download and comprehensive analysis,you can also send control commands through the gateway to the observation point to control the water quality observation process,allowing users to configure and control data acquisition parameters according to the actual monitoring needs,the formation of a feedback mechanism to improve water quality monitoring process management.The innovations of this article are:(1)For the problem of lagging in the construction of the monitoring platform,this paper initiated the establishment of a unified monitoring platform framework based on fixed points and ship-based,unified framework to facilitate inter-regional data format unification and data sharing,Users can be extended on the basis of the framework according to actual needs and application scenarios,the entire framework has good scalability and applicability.(2)On the basis of the framework design,we carried out the design and implementation of near-shore water quality monitoring system,we also took the use of modern rapid development of Internet of things technology,communication technology.These all improved the monitoring system automation and real-time monitoring capabilities;Monitoring and service integration,data collection,data processing,data analysis,real-time display and data acquisition and control and other functions are integrated in one,thus to form a complete and practical system.All the above could improve the near-shore marine monitoring and management level;Monitoring system uses modular development,which is convenient to system developers for system expansion and maintenance.
