Due to the irreplaceable advantages of 5G communication technology, there is no need to carry out complex bridge and wiring works in the construction of the network structure of smart buildings It is convenient and flexible to install, easy to expand and transform. This paper uses the special advantages of 5G-communication technology to apply 5G communication technology to intelligent buildings. This article first designs different subsystems based on different functions. Then, the local area networks composed of various subsystems distributed in the building are connected together through a 5G network. Finally, the basic centralized topology is adopted, and the building automatic control system installed in the public facilities in the middle of the plant is used as the network centre to communicate with each sub local area network through the bridge of 5G. In this paper, through the centralized monitoring and unified management of the distributed subsystems, and using the same monitoring interface to manage the different subsystems on a platform, the ultimate cost-effective system integration solution is finally achieved with the least investment optimal performance.

由于5G通信技术无可替代的优势，在智能建筑网络结构的建设中无需进行复杂的桥梁和布线工作，安装方便灵活，易于扩展和改造。本文利用5G通信技术的特殊优势，将5G通信技术应用于智能建筑。本文首先根据不同的功能设计了不同的子系统。然后，由分布在建筑物中的各种子系统组成的局域网通过5G网络连接在一起。最后，采用基本的集中式拓扑，工厂中部公共设施中安装的建筑物自动控制系统用作网络中心，通过5G桥接器与每个子局域网进行通信。本文通过对分布式子系统的集中监视和统一管理，并使用相同的监视接口来管理平台上的不同子系统，最终以最低的投资最佳性能实现了最终的经济高效的系统集成解决方案。
