在船舶动力定位系统中利用无线传感器网络进行数据融合

Data fusion based on wireless sensor network in ship dynamic positioning system

目前,不管从纵向还是横向上来看,人们对海洋的开发和探索都在不断加深。而船舶是目前海上作业的主要工具之一,因此,必须为其装备精确的动力定位控制系统。其主要作用是通过定位和传感器监测船舶以及海洋环境的状况。由于获取的数据量非常大,这就需要通过特殊算法对这些数据进行精简和管理,以期充分利用这些数据来提高系统的精确度和可靠性。本文结合最新的无线传感网络技术和传统的船舶动力定位控制系统技术,充分研究了数据融合方法。

At present,no matter from the vertical or horizontal point of view,the development and exploration of the ocean are constantly deepening. And the ship is one of the main tools of the sea work at present,therefore,it is necessary to equip the precise dynamic positioning control system for its equipment.Its role is largely through the positioning and sensor monitoring the status of the ships and the marine environment. Because the amount of data is very large,it is needed to streamline and manage these data through a special algorithm to make full use of these data to improve the accuracy and reliability of the system. In this paper,based on the latest technology of wireless sensor network and traditional ship power positioning control system,the method of data fusion is studied in this paper.
