Research On Water Surface Network Technology And Marine Hydrodynamic Monitoring Data Mining Based On LoRa Mechanism

With the development of the marine economy,human marine activities are becoming more and more frequent,and marine hydrodynamics have a greater impact on human activities.Research on marine hydrodynamics for oil spill monitoring and diffusion control,red tide development and traceability,tracking and control of marine drift garbage,etc.There are significant value applications.The current methods of studying marine hydrodynamics include ARGO systems,numerical simulations,and remote sensing technologies.However,these technical methods have the disadvantages of high cost,difficulty in delivery,insufficient precision of data collection,and limited coverage.In order to collect marine data quickly and cost-effectively and realize the monitoring of marine hydrodynamics,the water surface network technology based on the LoRa mechanism is used.A large number of micro-buoys that can move with the tide are collected to collect marine data,and the data visualization technology is applied to marine water dynamic data.In this paper,narrow-band IoT technology is used to design a micro-buoy with the Beidou positioning function based on the LoRa communication mechanism,and a water surface wireless Ad-Hoc network is constructed within a certain sea area;taking the Xiamen Bay sea area as a research area,a hydrodynamic simulation model is established by A large number of micro-buoys with tidal currents were deployed in the waters of Xiamen Bay to collect the hydrodynamic parameters of the waters;through the processing and analysis of simulation data and measured data,the hydrodynamic data of the seas were visualized,and the hydrodynamic balance of Xiamen Bay and the Jiulong Estuary Sediment tracking application.
