摘　　要：针对传统通信信息实时定位方法,存在定位误差最优,且实时性较差的问题,提出一种移动物联网区域通信信息实时定位方法。方法根据读写终端设备接收由标签发送的信号,对其进行解调以获得到达时间信息从而得到距离方程,利用泰勒公式得出标签位置,引入伪造随机代码对标签信息实施调制,通过帧头达成信息的采集与追踪任务,最终运用多普勒频移实现目标的实时定位。经仿真验证,上述方法不仅传输延迟时间较短,且定位精准度较高。Traditionally, the real-time positioning method of communication information has large positioning errors. Therefore, a method of real-time positioning for regional communication information in mobile Internet of Things was proposed. In this method, the signals sent by the tag were received from the read-write terminal device, and then they were demodulated to obtain the arrival time information and the distance equation. Moreover, Taylor formula was used to obtain the tag position. The fake random code was introduced to modulate the tag information. The task of information collection and information tracking was achieved by frame header. Finally, Doppler frequency shift was used to achieve the real-time positioning for the target. Simulation results prove that the proposed method has shorter transmission delay and higher positioning accuracy.
