Description

Building element collaborative installation protocol, method and system based on BIM data chain Technical Field The invention relates to the field of intelligent construction and building industrialization, in particular to a Building Information Model (BIM) data chain-based cooperative installation protocol, method and system for building elements. Background Currently, the construction industry is undergoing a transition from traditional manual construction to industrialized and digitized construction. Although BIM technology has been widely used at the design end to achieve the design of high-level digitization, the construction end still relies heavily on the experience of workers to manually interpret, pay-off and install, and there are serious "digital faults". The lack of accurate and automatic connecting bridges between the digital model of the design end and the physical world of the construction end leads to the pain points of the industries such as 'prefabrication speed, installation speed', 'installation get up and installation inaccuracy'. In the prior art, the installation of the components mainly depends on two-dimensional drawings and manual measurement and positioning, and the precision and the efficiency are low. While there have been individual attempts to use BIM models for construction simulation, a unified, drivable, feedback-able data chain throughout the entire life cycle of the component (design, production, logistics, construction) has not been formed. The lack of a real-time, closed-loop, collaborative protocol between the mounting actions of the physical components and the instructions of the digital model does not allow for true "data driven build". Therefore, there is a need for a synergistic protocol and method that enables full-industry-chain digital tomography to be enabled, converting BIM data into accurate physical installation actions without loss and automatically. Disclosure of Invention Object of the invention The invention aims to overcome the defects in the prior art and provides a building element collaborative installation protocol, a method and a system based on BIM data chains. The method has the core purposes of establishing a data backbone network penetrating through design, production and construction, converting digital instructions into physical actions through a unified protocol, realizing quick, accurate and automatic installation of building components, and promoting the fundamental conversion of a construction mode from craftsman experience to digital flow. (II) technical scheme In order to achieve the above purpose, the invention adopts the following technical scheme: in a first aspect, the present invention provides a method for collaborative installation of components based on a BIM data chain, which is characterized in that three steps are connected end to form a complete "digital-physical" closed loop: 1. And a data chain construction step, namely creating and maintaining a unified data chain with the unique identification of the component as an index. The data chain synchronizes and correlates all critical data of the component over the full life cycle (design, factory production, field installation), including its geometrical properties, material information, design coordinates in the BIM model, manufacturing coordinates at the factory, and target installation coordinates and real-time status at the construction site. 2. And generating and issuing a coordinate instruction, namely automatically generating a space coordinate instruction which can be understood and executed by an on-site installation executing mechanism (such as a mechanical arm, an adjustable position supporting frame and a guiding device) through a built-in coordinate conversion engine based on the target installation coordinate of the component in the data chain. The instructions are issued in real-time over a wireless network to an installation control system, such as an edge computing unit or a field control unit deployed in the field, that is bound to the particular component. 3. And the installation, execution and state feedback step, namely the on-site control unit drives the execution mechanism, and the guide member or the alignment device moves to the space pose appointed by the instruction. In the installation process, the actual pose and locking state of the component are acquired through a feedback mechanism of the sensor or the programmable physical interface, the information is transmitted back to the data chain in real time, the component state is updated, and the closed loop is completed. In a second aspect, the present invention provides a system for collaborative installation of data chains of building elements for implementing the above method, characterized in that a three-layer architecture "cloud-edge-end" is adopted: and the cloud cooperative platform is used as a data center, stores and manages a unified data chain and runs a coordinate conversion and task sc
