The IoT platform of Webuild sets up enriched and connecting neural networks for buildings. Currently, over 100 kinds of models of things are built in, compatible with more than 600 types of subsystem equipment and able to quickly connect to the equipment of the IoT and open up the bottom data of the BIM model to make unified visualized management and data analysis of various subsystems, data information and service resources, which greatly enhances the management of operation and maintenance and comprehensive service in the building.Application of the kit of Webuild reduces the costs and improves the efficiency of the operation of the building and makes it safe and reliable. Take the BIM-based architectural three-dimension visualized system, safe fire control management system, energy and efficiency management system and equipment and facility operation and management system for example.
