摘要

为实现室内实时高精确定位,设计了基于RSSI的实时精确定位系统。首先基于RSSI测距原理,建立强度与距离数学模型把强度转化为距离,然后采用改进加权质心算法来进行定位,并把定位误差作为目标函数,最后运用简化粒子群优化算法对目标函数进行全局最优值搜索,采用C/S网络架构和多线程技术实现了实时同步获取RSSI值,采用GUI设计了定位系统界面,实现了定位结果实时动态显示。测试结果表明:系统实现了室内实时高精确定位。
        In order to realize the real-time and accurate positioning in the room,A real-time precise positioning system is designed based on Received Signal Strength Indicator( RSSI). Firstly,based on the principle of RSSI distance measurement,the strength and distance mathematical model is established to transform the signal intensity into distance,then the improved weighted centroid algorithm is used to locate the target,and the positioning error is taken as the objective function. Finally,the simplified particle swarm optimization algorithm is used to optimize the objective function. The C/S network architecture and the multi-thread technology are used to obtain the RSSI value.The positioning system interface is designed by using the GUI. In the end,the real-time dynamic display of the positioning is realized. The test result shows that the system realizes the high precision positioning in the room
