摘要
本文分析了现有楼宇自动化系统的特点和实际工程应用中存在的问题,并从网络结构和功能角度论述了楼宇自动化系统的发展历程。然后,针对楼宇自动化的空间分布特性,本文提出了一种面向楼宇自动化任务的泛总线网络架构,分别介绍了泛总线网络的基本特征、运行机制及标准化信息模型。最后,以变风量空调系统为例,完成了变风量空调系统泛总线控制平台软硬件的设计与关键技术的开发,结果表明基于泛总线网络架构的楼宇自动化系统集成技术解决方案极具工程应用潜力。
Characteristics and problems of building automation system（ BAS） existed in practical engineering applications are analyzed,and the development history of BAS is discussed from the perspective of network structure and function services. Based on the space distribution feature, the architecture of task-oriented generalized fieldbus network of BAS is presented. Then the essential feature, operation mechanism and standardized information model are introduced. Taking variable air volume air condition system as an example,the paper presents the design and development of software and hardware of the control platform for this system. The result shows that the integrated solution based the task-oriented generalized fieldbus network of BAS has great potential for engineering application.
