摘　　要：针对舰船内部环境复杂,难以实现精准定位的问题,本文针对窄带物联网(NB-IoT)通信环境,提出一种基于信标定位的舰船内部精准定位技术。首先,在舰船内部的关键位置部署NB-IoT信标节点,利用NBIoT核心网络,将信标节点定期发送的包含位置信息的信号传送至NB-IoT云平台。然后,在NB-IoT云平台中,整理并汇集定位数据,再将数据传送至定位应用服务器。最后,利用定位应用服务器选取距离边界模型,构建舰船内部的信标定位信号传输模型。依据所构建的信号传输模型,利用同步解算方法,通过线性解法求解舰船内部信标位置,实现舰船内部的精准定位。实验结果表明,该技术的定位覆盖率高于98%,平均定位误差低于1 m,说明该技术能够实现对舰船内部的精准定位。In response to the complex internal environment of ships and the difficulty in achieving precise positioning,this study proposes a beacon based precise positioning technology for ships in NB-IoT communication environments.Firstly,NB-IoT beacon nodes are deployed at key locations inside the ship,utilizing the NB-IoT core network to transmit signals containing location information periodically sent by the beacon nodes to the NB-IoT cloud platform.Then,in the NB-IoT cloud platform,the positioning data is organized and collected,and then transmitted to the positioning application server.Finally,the distance boundary model is selected using the positioning application server to construct a beacon positioning signal transmission model inside the ship.Based on the constructed signal transmission model,the synchronous solution method is used to solve the position of the internal beacon of the ship through linear solution,achieving accurate positioning inside the ship.The experimental results show that the positioning coverage of this technology is higher than 98%,and the average positioning error is less than 1m,indicating that this technology can achieve precise positioning of the interior of ships.
