摘　　要：该文提出一种采用低成本、低功耗、可靠性强的Zigbee技术,利用多片定向天线对所指定的区域做信号源侦测,降低信号侦测死角因素的无线定位系统。天线信号强度指示RSSI经由微处理器的定位算法处理,得到被测物体的具体方向。实验结果表明:能实现全向定位报警。System in the essay uses the Zigbee technology which is low - cost, low power consumption and high reliability. It equipped with several directional antennas to decrease factor of the dead angle of detection. The right direction will be shown after RSSI obtained from antennas by turns is processed by MCU using locating method. The result showed that it can alert and locate in omni - direction.

关 键 词：无线定位系统 天线信号强度指示 定位算法
