摘　　要：随着智能化技术的飞速发展,文章针对目前在建筑施工过程中传统定位技术对人员安全定位存在的定位精度低、定位过程烦琐问题,提出了一种基于无线传感器网络的分布式定位技术。通过在无线传感器网络节点间部署大量的智能定位安全帽作为锚节点,形成无线传感器网络,实现在智慧施工过程中的人员安全定位。通过计算智能定位安全帽节点间距离和角度测量值之间的关系,并将该关系引入基于最小二乘法的节点位置估计模型,采用加权最小二乘法完成施工人员安全帽节点的相对位置估计。最后通过该方法的实际应用表明,该方法能够有效提高施工人员在施工现场的定位精度和定位效率,在智慧施工中有较高的应用价值。With the rapid development of intelligent technology,this paper proposes a distributed positioning technology based on wireless sensor networks to address the problems of low positioning accuracy and cumbersome positioning process in traditional positioning technology for personnel safety during construction.By deploying a large number of intelligent positioning helmets as anchor nodes between wireless sensor network nodes,a wireless sensor network is formed to achieve personnel safety positioning in the intelligent construction process.By calculating the relationship between the distance and angle measurement values between intelligent positioning safety helmet nodes,and introducing this relationship into the node position estimation model based on the least squares method,the weighted least squares method is used to complete the relative position estimation of construction personnel safety helmet nodes.Finally,the practical application of this method shows that it can effectively improve the positioning accuracy and efficiency of construction personnel on the construction site,and has high application value in smart construction.
