摘要:: 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。

Abstract:: 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.
