摘　　要：精确的室内定位方法是发展工业4.0时代的重要基础。然而,精准的定位往往需要大量的基础投入。本文探索基于超高频RFID的多标签室内定位方法,希望在定位精度和成本上取得平衡。传统RSSI信号指纹定位方法在实际应用中较为复杂,研究利用多标签简化地图信号指纹数据库的算法,降低构建的时间成本,并在实验中取得平均定位误差优于RSSI传统定位的结果,满足了室内定位的精度要求,具有定位成本低、定位精度高、抗干扰能力强等特点。Accurate indoor positioning method is an important basis for the development of Industry 4.0 era.However,accurate positioning often requires a lot of basic investment.This paper explores a multi tag indoor location method based on UHF RFID,hoping to achieve a balance between location accuracy and cost.The traditional RSSI signal fingerprint location method is more complex in practical application.The research simplifies the algorithm of map signal fingerprint database by using multiple tags,reduces the time cost of construction,and obtains the result that the average location error is better than the traditional RSSI location in the experiment,which meets the accuracy requirements of indoor location,and has the characteristics of low location cost,high location accuracy,and strong anti-interference ability.
