摘要:为了提高大型工程贵重物资施工现场监控、统计及防盗管理水平，在传统以人管理方式为主的基础上，采用了基于超宽带无线射频技术(UWB)的贵重物资施工现场定位技术。根据静态封闭式及动态开放式定位试验，分别提出UWB信号接收器及标签发射器的施工现场布置方式，并建议在实践运用中，在静态封闭式环境下，以UWB定位技术为主，以人管理为辅；在动态开放式环境下，以人管理为主，以UWB定位技术为辅。

Abstract: To improve the monitoring, statistics and anti-theft management level of the valuable materials in the construction site, the new location technology for valuable materials on construction site based on the ultra-wideband radio frequency technology (UWB) is adopted in addition to traditional approach of people-oriented management. Based on positioning tests under the static closed and dynamic open environment separately, two construction site layout methods are put forward using UWB signal receiver and tag transmitter, which are suggested in practice. It is better to choose UWB positioning as main technique in the static closed environment, while manual as main management in the dynamic open environment.
