Abstract
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关键词
