基于蓝牙信标的船舶舱室人员定位技术OA
Crew Locating Technology in Ship Cabins Based on Bluetooth Beacons
由于船舶舱室构造材质具有金属特征,形成特殊电磁环境,船舶舱室内人员位置难以无线定位.针对该问题,通过在某科考船上采集船舱内不同位置的蓝牙信号强度,分析蓝牙信号强度的时空分布特性,构建蓝牙无线信号空间传播模型;同时,为了降低计算复杂度和提高定位实时性,采用多边最小二乘定位方法进行定位.实验结果表明,蓝牙无线信号空间传播模型受到船体建造材质的影响,在船舶舱室内,学术厅与走廊的环境影响因子分别为 2.02 和 2.23,多边最小二乘定位方法的平均定位精度为1.68 m,可以快速定位船舶舱室人员.
Due to the metallic structural materials of ship cabins,which create unique electromagnetic en-vironments,locating the crew in ship cabins is difficult to achieve.To address these issues,Bluetooth signal strengths data at different locations within a scientific experdition vessel were collected and analyzed to investi-gate their spatiotemporal distribution characteristics.A spatial propagation model for Bluetooth signals was es-tablished.Additionally,a multilateral least squares positioning method was adopted to reduce computational complexity and improve real-time performance.The experimental results demonstrate that the spatial propaga-tion model of Bluetooth signals is influenced by cabin materials,with environmental influence factors of 2.02 in academic halls and 2.23 in corridors.The multilateral least squares method achieved an average positioning accuracy of 1.68 m.The Bluetooth beacon-based locating technology enables rapid locating the crew in ship cabins.
