摘要
为了提高室内无线传感器网络的定位精度,设计了一个基于UWB的无线传感器网络定位系统,该系统在上位机软件上运用TDOA算法进行定位计算,硬件设计上锚节点采用deca Wave公司生产的DW1000为无线收发芯片,在其控制器STM32内部写入嵌入式程序,完成数据记录、收发。该系统理论定位精度可达到10cm,抗多径能力强、稳定性高,为无线网络传感器定位提供了更多的参考。
In order to improve the positioning accuracy of wireless sensor networks. In this paper, we propose a wireless sensor network positioning system based on UWB. The system use TDOA algorithms on PC for positioning calculation. In hardware design, we use decaWave company＇s DW1000 Wireless transceiver chip as Anchor node to receive information. We can write the embedded program in its internal control STM32 to accomplish record of date, send and receive. The positioning system theory positioning accuracy can reach 10cm.They have Anti-multipath capability, high stability abilities, it provides more references to wireless sensor networks indoor location.
