摘要
利用ZigBee无线通信网络中的无线信号强度指示(RSSI)进行室内射频(RF)定位。将通信子系统作为定位硬件,采用三边测量定位算法获得移动网络节点的位置,定位精度很大程度上取决于RSSI值的质量。为了将RSSI值应用于定位子系统,采用补偿滤波器进行滤波,以克服RSSI值波动限制,从而在移动节点定位方面获得更好效果。
Indoor Radio Frequency(RF) positioning was conducted based on Received Signal Strength Indication(RSSI) of ZigBee Wireless Network. Communication subsystem being used as positioning hardware, the locations of mobile network nodes were obtained by trilateral measurement algorithm. Its accuracy depends largely on the quality of the RSSI being tested. In order to apply the RSSI value to the positioning subsystem, the compensation filter was used, so as to overcome the fluctuation limit of the RSSI value and get a better effect in positioning.
