摘要
为了解决当前室内定位系统精确度低、可靠性差的缺点,设计并实现了一种基于无线传感器网络的室内定位系统。系统硬件以CC2530为主控芯片,在节点自主定位基础上增加了上位机辅助定位模式,在该模式下调用可降低环境变化对定位精度产生干扰的加权质心定位算法。在本定位系统上也可以随时修改上位机定位算法,方便以后作进一步地改进。经测试表明:本系统运行稳定,易于维护,定位精度较其他定位平台大大提高。
In order to solve the problems of low accuracy,low reliability of the current indoor location system,the present study designed and implemented a kind of indoor positioning system based on Wireless Sensor Network.This system taking CC2530 as the main controlling chip,on the basis of node autonomous positioning,it adds a PC-assisted positioning mode,the improved weighted centroid localization algorithm was invoked.This algorithm could decrease the disturbance of environment change on the position precision.On this positioning system,PC localization algorithm can be modified at any time;it is convenient for further improvement.The test shows that the system is stable,easy to maintain,and improve the positioning precision better than other positioning platforms.
