摘　　要：随着无线通信和无线传感器网络技术的发展,人们对活动频繁的室内定位要求越来越高,室内定位服务存在大量应用需求,因此研究室内定位技术具有十分重要的意义。基于ZigBee的室内定位技术定位准确,花费成本少,可靠性好,成为室内定位技术的主流技术之一。设计的系统主要包括网关、参考节点、盲节点、上位机监控软件以及RSSI定位算法研究5个部分。网关采用STM32进行主控,集成了ZigBee模块和WIFI模块。参考节点和盲节点采用CC2530进行ZigBee的通信,实现节点之间无线射频信号的收发。上位机监控系统采用改进的三边测距算法计算盲节点的坐标,并通过可视化的界面显示出来。通过进行检测验证实验,证明了该设计系统的可行性和有效性。With the rapid development of wireless communication and wireless sensor network, there were a large number of application requirements of indoor positioning service, so it was very significant to the study of indoor positioning tech- nology. The paper studied the indoor real-time location technology of ZigBee and designs the system. The whole system includes gateway, reference node, the blind node, monitoring software of computer and RSSI location algorithm. STM32 was used to control the gateway, which was integrated ZigBee module and WiFi module. Reference node and blind node were communicated through CC2530. Monitoring system calculated the blind nodes＇ coordinate based on the improved three edge location algorithm. Using computer simulate it, the results show that this method has low consumption, the characteristics of high precision, and has certain practical value.
