自组网的小尺度海域水动力分析

Research on Hydrodynamics of Small-scale Sea Areas Based on AdHoc Network

为了快速精确地监测小尺度海域水动力信息,应用窄带物联网技术,在一定尺度海域内构建无线自组网络,设计基于LoRa无线通信机制,带北斗定位功能的微型浮标和基站系统。结合水动力学建模结果,在厦门湾海域内投放大量微型浮标,采集该海域水动力学参数数据。借助海域动态监测大数据公共服务平台,集中接收和处理数据。实验结果表明:该方法可以有效地实现数据共享及小尺度海域水动力学数据监测。

In order to quickly and accurately monitor hydrodynamic information in small-scale sea areas,a narrow-band IoT technology was applied to construct a wireless self-organizing network in certain scale sea areas.A system of micro-buoys and base stations with BDS positioning function based on LoRa wireless communication mechanism was designed.Combined with the results fromhy drodynamic modeling,a large number of microbuoys were placed in the sea areas to collect hydrodynamic parameter data.Experimental results show that this method can effectively realize data sharing and small-scale hydrodynamic data monitoring.
