当前由高处坠落引起的安全事故占建筑业安全生产事故的比例最高，建筑工人高处坠落安全问题迫切需要信息化技术来实现安全管理的自动化。基于此，本文将BIM、云计算、RFID技术结合，通过分析高处坠落事故因素，提出系统构建思路并有针对性的设计预警系统功能模块，进而构建基于Cloud-BIM的建筑工人高处坠落安全预警系统，划分高处坠落预警标准和危险区域规则，设计预警系统运行流程，合理选择RFID设备并布置阅读器。该系统的应用实现了对高处坠落安全管理的信息化，可有效的降低建筑工人高处坠落事故发生率，对建筑施工安全管理的信息化进程具有重要意义。

At present, safety accidents caused by falling from a high place account for the highest proportion in the construction industry. The safety of construction workers falling from heights urgently requires information technology to automate safety management.Based on this,this paper combines BIM,cloud computing and RFID technology,by analyzing the factors of falling accidents at high places and proposing system construction ideas and targeted design early warning system function modules,then build a construction worker's high fall safety warning system based on Cloud-BIM,divide the rules and warning standards for high-altitude hazardous areas,design the operation process of the early warning system,reasonable selection of RFID devices and placement of readers.The application of the system realizes the information of the safety management of falling from a height,it c an effectively reduce the incidence of construction workers falling from high places,it is of great significance to the information development of building construction safety management.
