摘要:在总结分析智慧建筑系统集成技术与行业现状基础上，剖析目前智慧建筑系统集成尚存的难点，提出基于数字孪生理论的工程全生命周期系统集成模式，即智慧建筑数字孪生系统集成法。给出了基于组态软件平台的数字孪生建筑集成系统开发实现方法，指出基于数字孪生建筑集成系统的一个突出趋势是共享化。设施、工具、信息、数据、服务等都可以通过共享平台实现共享和交换。建议城市信息模型(CIM)宜采用基于模型的复杂系统工程思维，在数字孪生建筑互联互通基础上建立，这也是当前快速构建CIM的一条可行路径。

Abstract: On the basis of summarizing and analyzing the current situation of intelligent building system integration technology and industry, this paper analyzes the existing difficulties of intelligent building system integration, and puts forward the system integration mode of whole life cycle of Engineering Based on digital twin theory, that is, the digital twin system integration method of intelligent building. This paper presents the development and implementation method of digital twin building integration system based on configuration software platform, and points out that a prominent trend of digital twin building integration system is sharing. Facilities, tools, information, data and services can be shared and exchanged through the sharing platform. It is suggested that the urban information model (CIM) should adopt the complex system engineering thinking based on the model, and be established on the basis of the interconnection of digital twin buildings. This is also a feasible way to construct CIM rapidly at present.
