摘要
针对传统的自动跟随设备存在使用条件苛刻、定位跟随能力差等缺陷,提出一个基于UWB技术的室内智能定位跟随系统。讨论双基站的跟随模型,在误差分析的基础上,提出带误差容忍度的实时纠偏自动跟随算法。针对双基站跟随模型的“完美背离”等问题做进一步优化处理,提出三基站跟随模型,解决双基站存在的问题,提高跟随效率。实验结果表明,基于该系统的设备可以正确自动跟随目标。
To avoid the defects such as strict application conditions and poor positioning ability of traditional automatic following equipment,this paper proposes and designs an indoor intelligent following system based on UWB(Ultra Wideband)technology.We discussed the following model with two-base-station and proposed a real-time correction following algorithm with error tolerance based on error analysis;The following model with three base-station was proposed to solve the special problems like“perfect deviation”of two-base-station and improve following efficiency.The experimental results show that devices based on this system can follow the target correctly.
