摘要
船舶定位对航行安全、避碰、远程监控以及港口船舶管理等方面都有重要意义。针对目前船舶三维定位存在精度低、抗干扰能力弱等的问题,本文提出了基于无线传感器网络节点的船舶定位方法。研究无线传感器网络原理和构成,并在此基础上,设计了节点自定位算法和船舶三维定位算法。最后,通过实验验证三维定位算法的精度。
Ship positioning plays an important role in navigation safety, collision avoidance, remote monitoring and port ship management. Wireless sensor network(WSN) is a self-organizing network system composed of a large number of sensors with data acquisition, data processing and wireless communication. It has unique advantages and prospects. Aiming at the problems of 3D positioning of ships, a ship positioning method based on WSN nodes is proposed in this paper. The principle and structure of wireless sensor networks are studied. Based on this, node localization algorithm and 3D localization algorithm are proposed. Finally, simulation experiments are carried out to verify the accuracy of the three dimensional localization algorithm.
