基于LonWorks现场总线技术的校园建筑智能化系统

为了提高楼宇的智能化水平,发挥LonWorks总线的多功能I/O与网络通讯功能应用更开放,扩展更容易等优点,设计了一种基于LonWorks现场总线的校园楼宇自控系统,该系统包括冷水机组子系统、空调子系统、给排水子系统、热水锅炉子系统、供配电子系统和智能照明子系统等.系统采用基于LonWorks技术的总线型拓扑结构,选用HONEYWELL公司最新的开放楼宇集成管理组件EBI作为系统管理软件,开发了供配电、智能照明以及冷水机组与EBI之间的接口,实现了数据信息的集中控制和综合管理.

Intelligent system of campus buildings based on LonWorks field bus

To enhance the level of intelligence of buildings and exert the open and ease of extension of the Lonworks field bus due to its integration of multi-I/O and network communication.An automatic control system based on LonWorks field bus for the campus building is developed.This system includes cold water unit subsystem,air conditioning subsystem,draining water subsystem,hot water boiler subsystem,electricity supply and distribution subsystem and the intelligent illumination subsystem,etc.The bus topological architecture based on LonWorks technology,and the newly open building integration and management discreteness EBI(Enterprise Building Integrator)from HONEYWELL Company are adopted to the system.The interfaces between EBI and electricity supply and distribution subsystem,the intelligent illumination as well as cold water unit are developed to realize common control and synthetic management of the data message.
