curtain wall risk control system

In view of the current situation of the existing curtain wall building and the problems and pain points existing in the traditional management, relying on the core technology of iot loT+BIM + GlS+CIM, equipped with smart phones, tablets and office computer information tools, the management, control and early warning of the building curtain wall as the landing point. CIM refers to City Information Modeling and City Intelligent Model. Digital twin refers to the use of model, sensor update, operation history and other data, integrated multi-disciplinary and multi-probability simulation process, complete mapping in virtual space, so as to show the whole life cycle process of physical city buildings. Through the combination of UAV technology, image AI processing, 3D point cloud and Internet of Things, a virtual real city 3D scene with 1:1 high accuracy and high restoration can be created in the cloud. The scene created not only contains the panoramic OBJ model and 3D lightweight BIM model of a single building, street and administrative district, but also innovatively integrates GIS, latitude and longitude information and camera perspective coordinate system information of the model, and finally forms CIM system platform of twin digital city. The CIM of the system platform is like a digital baseboard for the visualized big data management of the whole ecological network. It has a "platform" and "ecosystem" pattern, which makes a solid and sufficient long-term preparation for the scalability of the platform types of curtain wall systems and the extensibility of external enabling access. In addition, on the entry point of risk control of the curtain wall of architectural complex, we scrupulously cut into it thoroughly and strive to be penetrating. The first developed system platform supports the classification of the concrete components of the building curtain wall to view and mark the risk status, and integrates the marked risk status into the model and saves it as historical archives. In addition to the specific components of the curtain wall structure which can mark the risk state, the whole model can also mark the risk points and risk areas of the hidden trouble parts, and it will also be saved and archived. Secondly, the project laid the building information data collection channel, and integrated into the main functions of the system platform. Through the system platform, archives such as building number, safety maintenance person, floor height, curtain wall area type and previous house investigation report can be quickly obtained. That is, the system platform will be the whole life cycle of the building, such as project approval, construction, completion, and management, until demolition or reconstruction and other related information digital integration; Finally, the system platform focuses on the feature that the building curtain wall has a useful life and a large stock. Through stock of both the point support curtain wall, the present situation and existed problems in the traditional management of further exploration and thinking has set up a routine safety inspection for the curtain wall, regular safety inspection, special safety inspection and material use fixed number of year of function module. At the same time, there is also a core early warning and prevention and control section related to iot sensors.
