智能建筑作为信息时代的必然产物体现了高科技与现代建筑的巧妙结合。而现场总线控制系统(FCS)以其结构简单、通信转输可靠、节点智能化等优点大有取代传统的集散型控削系统(DCS)之势。因此,目前流行的楼宇自动化系统(BAS)都在逐渐引入现场总线技术,文章阐述了现场总线控制系统在智能建筑中的应用前景。为进一步发挥现场总线的技术优势,弥补现有系统的不足,在分析目前国内外BAS的基础上,文章又提出了用LonWorks现场总线技术实现的新型楼宇自动化控制系统,并较为详细地介绍了用LonWorks构成的BAS在结构、通信、网络等方面的特点,最后给出了BAS具体的设计开发步骤。
As an inevitable product of the information age, intelligent building embodies the ingenious combination of high technology and modern architecture. The fieldbus control system (FCS) has replaced the traditional distributed control system (DCS) with its simple structure, reliable communication transfer, intelligent node and so on. Therefore, the current popular Building Automation System (BAS) are gradually introducing fieldbus technology, the article expounds the fieldbus control system in the intelligent building application prospects. In order to make full use of the technical advantages of the field bus to make up for the deficiencies of the existing system, based on the analysis of the current domestic and foreign BAS, the article also presents a new building automation control system with LonWorks fieldbus technology, and introduces in more detail the use of LonWorks composition of the BAS in the structure, communications, network and other aspects of the characteristics of the final design given BAS specific development steps.
