摘要
随着蓝牙设备的普及以及蓝牙4.0标准规范的应用推广,使得依据蓝牙设备的室内定位技术发展迅速.针对室内定位服务的社会需求,搭建了利用线性加权算法实现室内移动蓝牙设备的实时定位系统.该系统把线性加权算法与蓝牙设备结合在一起,通过对蓝牙无线链路通信的信号强度,链路质量值,传输功率级等参数的加权运算处理,实现对移动设备的算法定位.仿真过程中该算法的平均定位误差在1.5m以下,满足一定精度要求.
With the popularity of Bluetooth devices and the promotion of Bluetooth Specification Version 4.0, the indoor location technology based on the Bluetooth devices develops rapidly. Aiming at the huge demands of the indoor location service, a precise Bluetooth positioning system with a linear-weighted algorithm is presented. The system combines Bluetooth devices with linear-weighted algorithm. It locates the mobile devices through weighting the value of the received signal strength indicator, the link quality, and the transmit power level of the Bluetooth wireless communication link. The simulation results show that the average of location error in this algorithm is less than 1.5m, which meets certain accuracy requirements.
