Based on the intelligent information technology of production and construction management of assembled building products, bim, Internet of Things, cloud computing, industrial Internet, mobile Internet and other information technologies are applied to realize the factory production, assembly construction and information management of assembled buildings. By controlling the deepening design, material management and product manufacturing in the production process of prefabricated building products, as well as the management of product entry, site yard management and construction pre-assembly in the construction process, the information sharing between the production process and the construction process can be realized, the product quality and construction efficiency in the production process can be guaranteed, and the production and construction management level of prefabricated building products can be improved. 1, technical content (1) Establish a collaborative work mechanism, clarify collaborative work processes and results delivery contents, establish a corresponding management information platform for the whole process of production and construction, and realize cross-departmental and cross-stage information sharing. (2) Deepening design: Establish a deepening design model according to the design drawings and manufacturing requirements, and deliver the model to the manufacturing process. (3) Material management: unified identification of materials is carried out by using the bar code technology of the Internet of Things, and visual warehousing stacking management and multi-dimensional quality traceability management are realized by managing the whole process of receiving, sending, storing, receiving, using and returning materials. (4) Product manufacturing: unify the coding of personnel, processes and equipment. According to the product type, an automatic production line is established, equipment is managed on the Internet, the manufacturing process is carried out according to the process parameters, the production status is fed back, and the visual management of the production status is realized. (5) Product approach management: Using the bar code technology of the Internet of Things, the whole process of product quality can be traced, and the product approach progress can be viewed by product batch in BIM model, thus realizing visual management. (6) On-site yard management: The products are uniformly identified by using the bar code technology of the Internet of Things, and the space of the on-site yard is reasonably used to realize the visualization of product stacking management. (7) Management of construction pre-assembly: Use BIM technology to simulate the pre-assembly of products, reduce and correct assembly errors, and improve assembly efficiency. 2. The technical index (1) management information platform can centrally control the situation of deepening the design, material management and production process, monitor the production quality of products by using the relevant information of production links in the construction process, and improve the construction assembly efficiency through the construction pre-assembly management. (2) In the deepening design, the product codes (such as precast concrete and steel structure) shall be unified according to the deepening design standards (requirements) of various disciplines. ), use professional deepening design software to deepen the design work, reach the design depth required for production, and deliver it to the downstream. (3) In the material management, the material coding shall be unified according to the material classification standards (requirements) of various disciplines (such as precast concrete and steel structure). Information management of the whole process of receiving, sending, storing, receiving, using and returning materials. The technology of Internet of Things bar code and RFID bar code is applied to bind the location of materials and warehouses, and mobile devices such as scanning guns and mobile phones are used to collect bar code information on the spot. According to the simulation diagram of material warehouse, the visual management of material stacking is realized, and the traceability of quality control is realized through the management of multi-dimensional information such as manufacturer, size, appearance, specification and model of materials. (4) In the process of product manufacturing, the codes of personnel, technology and equipment should be unified according to the production standards (requirements) of various disciplines (such as precast concrete and steel structure). Manufacturers use the industrial internet to establish a network transmission system, which can support the equipment level at the process level and realize automatic manufacturing. (5) Using BIM technology, computer aided process planning (CAPP), process route simulation and other tools to make process documents, and can transmit process parameters to the corresponding equipment through the industrial Internet of Things system of the factory (such as transmitting cutting programs to cutting equipment). The production status of each process can be collected and uploaded by personnel reporting, bar code scanning or automatic equipment collection. (6) Applying the Internet of Things technology to the management of products entering the site, using mobile devices such as scanning guns and mobile phones to scan product barcodes and RFID barcodes, and automatically transmitting product information to the management information platform for product quality traceability management. According to the construction and installation plan, the entry status of each batch of products can be visually viewed in the BIM model to control the progress of the project. (7) In the field yard management, technologies such as Internet of Things bar code and RFID bar code are applied to bind product information and product location information, and mobile devices such as scanning guns and mobile phones are used to collect the field bar code information, so as to realize the visual management of product stacking according to the product warehouse simulation diagram and rationally organize and utilize the field yard space. (8) In the management of construction pre-assembly, BIM technology is used to analyze the virtual pre-assembly of products that need to be pre-assembled, and the assembly error is checked through the model or output report, so as to complete the deviation adjustment on the ground, reduce the pre-assembly cost and improve the assembly efficiency. (9) Cloud deployment can be adopted to improve the utilization rate of information resources and reduce the use cost of information resources. (10) should have the ability to integrate with relevant information systems. 3. Scope of application
It is suitable for in-depth design, material management and product manufacturing in the production process of assembled building products (such as steel structure, precast concrete and wood structure). ), as well as product approach management, site yard management and construction pre-assembly management in the construction process. 4.
