基于物联网的机场特种车辆定位系统研究

摘要

传统的机场特种车辆定位系统一般用车载GPS系统来实现,在机场建筑密集区会出现丢失信号的情况.基于对无线传感器网络定位算法的研究,结合无线传感器网络在机场环境下的特点,提出一种新的GPS/WSN数据融合定位系统.仿真结果表明,在卫星信号缺失情况下,该系统能够独立完成系统定位需求.%GPS system is generally used in the positioning system of the traditional airport speciality vehicles.The lost signal may happen in the concentrated airport buildings.Based on the research on wireless sensor network localization algorithm and according to the characteristics of the wireless sensor network environment at the airport,this paper puts forward a new method of GPS/WSN data fusion positioning.The simulation result shows that under the lost satellite signal,this system is still used to fulfil the requirement of the system positioning.
