Research on the Theory of IoT-Based Prefabricated Building Component Installation and Positioning System

The effective and timely management of component information is essential for the smooth running of construction projects. Especially at the phase of development of construction industrialization, the project form of organization, planning, supervision, collaboration, and communication should be conducive to the construction project. Timely and effective management of component information is a fundamental requirement for the development of prefabricated buildings. Tracking accurately and location of components precisely are good for managing the entire process of prefabricated buildings. Component tracking and positioning is a dynamic process that is closely related to the content of each phase of work. Therefore, based on the in-depth understanding of the construction process of prefabricated buildings, the paper analyzes and summarizes the spatial information of components needed for each stage of work, combining BIM technology and RFID technology, using digital measurement technology and positioning identification technology to establish an IoT-based inspection system for the installation and positioning of assembly building components to meet the requirements of whole life cycle component tracking and positioning.
