水面无线自组网装备研发与水动力学监测应用研究

Research and development of water surface wireless Ad-Hoc network equipment and application of hydrodynamic monitoring

应用窄带物联网技术,研发了一种能够快速构建半径100 km的水面无线网络,并通过投放大量抛弃式带北斗定位的微型浮标,动态采集水动力学数据。该技术能够解决采用传统海洋水动力学监测利用锚泊式大型浮标,固定在一个位置上采集数据的方法成本高、数据精细化程度不够的问题。由大量的海洋试验和研究证明,该方法在泥沙沉积、漂浮垃圾追踪、潮动力平衡、海水养殖环境评估等方面实用有效。

Traditional marine hydrodynamic monitoring uses large anchored buoys to collect data,which is expensive and space confined.This paper developed a surface wireless network with a radius of 100km,which can be quickly applied in the hydrodynamic monitoring by combination of a large number of abandoned microbuoys with Beidou positioning.The technology can solve the problems of high cost and insufficient data refinement in the traditional marine hydrodynamics monitoring,which uses large-scale mooring buoy for data collection at a fixed position.Results of many sea trails show that the method is practical and effective when used for tracking the sediment deposition and marine floating garbage,monitoring the balance of tidal dynamic,assessing the quality of mariculture environment and so on.
