摘要
文章提出了基于Deca Wave的单片收发一体射频芯片DW1000的UWB定位方案,设计了系统的软硬件框,讨论了相关定位算法及测距的优化算法。系统中被测节点(tag)与锚节(anchor)点通过双向TDOA算法等到两者之间的距离,tag与多个anchor的距离通过UWB通信被汇总至定位服务器,由定位服务器三角质心定位算法测算出tag的三维空间坐标。经实验研究表明,系统在LOS环境下具有较高的精度,在NLOS环境下也具有良好表现。
This paper presents an UWB positioning scheme based on Deca Wave single chip transceiver integrated RF chip DW1000 and designs the software and hardware architecture of the system, depicts its design and type selection, discusses correlation location algorithm and ranging optimization algorithm. The nodes in the system under test（tag） and anchor section（anchor） through the bidirectional TDOA algorithm when the distance between the two, tag and multiple anchor distance by UWB communication are aggregated to the location server, a location server triangle centroid location algorithm is used to calculate the 3D coordinates of tag. Experimental results show that the system has a high precision in the LOS environment, and also has a good performance in the NLOS environment.
