摘要
钢结构建筑作为现代建筑中主要的一种建筑结构类型,应用领域非常广泛.但钢结构建筑在搭建过程中,其关键承重结构需要严格按照设计规划的组合顺序进行搭建组装,否则可能造成不可估量的严重后果.为了实现钢结构建筑施工作业的精准管控,文章基于超宽带定位技术对钢结构建筑关键主材三维定位过程中的测距方法做了研究,基于模糊理论对标签与基站之间信号的非视距传播进行识别,并对其带来的非视距误差进行抑制,对传统的非对称双边双向测距方法进行了改进.实验结果表明,改进后的非对称双边双向测距方法的平均测距误差为0.221 3 m.
Abstract
As one of the main architectural structures in modem architecture,steel structure architecture is widely used.However,in the construction process of steel structure buildings,the key load-bearing structures should be constructed and assembled in strict accordance with the combination sequence of design planning,otherwise it may cause immeasurable serious consequences.In order to achieve accurate control of steel structure building construction,the paper studies the key technologies in 3D positioning of key main materials of steel structure building based on UWB positioning technology.Firstly,the non-line-of-sight propagation of the signal between the tag and the base station is identified based on the fuzzy theory,and the non-line-of-sight error caused by it is suppressed,which improves the traditional asymmetric double side two way ranging method.The experimental results show that the average ranging error of the improved asymmetric double side two way ranging method is 0.221 3 m.
