基于云雾边的智慧低碳建筑信息系统设计
Cloud-Fog-Edge Based Design of Intelligent Low-Carbon Building Information System

为加快大型建筑转型升级，推动信息系统高效低碳设计，分析了当前智慧建筑信息系统的设计现状，提出基于边缘计算的智慧建筑信息系统架构设计策略，通过IoT协议和Web协议连接“云层–雾层–边缘层”，研究了边缘计算在智慧建筑信息系统“低碳”和“智慧”控制目标下的子系统应用技术及设计方案，在下层的各个分散节点实现数据的分布式处理，在上层结点实现数据融合与决策，并给出一个智慧建筑信息系统的设计与运行实例。
In order to speed up the transformation and upgrading of large-scale buildings and promote the efficient and low-carbon design of information systems, this paper analyzes the current design status of intelligent building information systems, proposes the design strategy of intelligent building information system architecture based on edge computing, and studies the application technology of edge computing in the “low-carbon” and “smart” control goals of intelligent building information systems through the IoT protocol and Web protocol connection “cloud-fog-edge”. Distributed data processing is implemented at various decentralized nodes in the lower layer, data fusion and decision-making are implemented at upper nodes, and a design example of a smart building information subsystem is proposed.
