基于BIM 和RFID 的建筑工人高处坠落事故智能预警系统研究

为提高建筑工人高处坠落事故的预防水平，通过对建筑施工安全相关规范及事故案例的调查研究，对建筑工人高处坠落事故的危险区域进行定义及预警等级划分。基于建筑信息模型和无线传感网络技术，建立了建筑工人高处坠落事故智能预警系统，设计了系统结构、功能和运行流程。该系统可实现建筑工人实时定位和高处坠落事故智能预警；系统架构分为传感层、网络层、应用层，能分别实现信息采集、数据传输及状态分析；系统在建筑工人高处坠落事故的可视化识别与智能化预警方面具有优势。

Research of Intelligent Early Warning System for Falling Accidents Based on BIM and RFID for Construction Workers

In order to improve the prevention capacity of falling from high place on construction sites，an integrated intelligentearly warning system was established based on BIM and RFID technology. To establish the system，regulations concerningconstruction safety and accidents cases were investigated. Besides，the hazardous areas in falling accidents were defined and earlywarning levels were classified. Furthermore，the system structure，functions and process were designed. The researches revealed thatthe system is able to locate workers in real time and early warn the falling accidents successfully. The system can be divided intosensing layer，network layer and application layer. They can collect information，transmit data and analyze status，respectively. Thesystem has advantages in visual identifying and intelligent early warning the falling accidents.
