Research on Comprehensive Benefit Analysis Method of Prefabricated Buildings Based on BIM and RFID Technology

Abstract

There are safety problems among mechanical equipment, prefabricated components and construction personnel during the construction of prefabricated buildings. We use building information model and RFID technology to build a prefabricated building safety early warning platform. Firstly, through the demand analysis and system function design of the security early warning platform. Through the accident tree analysis of the dangerous sources of prefabricated building construction, it is obtained that the dangerous sources of prefabricated building construction are the unsafe behavior of people, the unsafe state of objects and the unsafe environment. Then we established three subsystems of security early warning platform based on BIM and RFID technology: data collection subsystem, data transmission subsystem and security early warning subsystem. At the same time, we display the corresponding area in red, green and yellow in the BIM model. The results show that the combination of RFID technology and BIM can quickly and accurately provide early warning of dangerous sources in the construction of prefabricated buildings.
