蓝牙手机室内定位系统

Indoor positioning system for bluetooth cell phone

设计并实现了一种基于蓝牙和Wi-Fi的低成本手机定位和信息发布平台。改进了已有蓝牙设备RSSI检测方案,能对多个手机同时定位;利用Wi-Fi和J2ME技术实现了手机对定位信息的接收和实时显示。实验结果表明系统具有定位准确、使用方便等特点,在目前硬件条件下为物联网应用提供了平台支持。

This paper introduced a low-cost platform for locating bluetooth cell phones and releasing position information.The authors improved the scheme of measuring Received Signal Strength Indication（RSSI） of bluetooth devices to locate multiple cell phones simultaneously,developed cell phone program to receive position information via Wi-Fi and display it on map.The experimental results show that the system is accurate in positioning and easy to use,and it provides a platform support for applications of Internet of Things（IOT） under current hardware condition.
