基于EXPRESS-G的BAS信息模型拓扑结构浅析

Analysis of Topological Structure of BAS Information Model Based on EXPRESS-G

基于智能建筑中典型的BAS,在CAD设计的基础上,将EXPRESS-G图形语言运用在BAS设计过程中,以达到在设计与施工过程中减少重复劳动,简化设计过程,降低成本的目的。建立一个包含设备列表、网络拓扑结构、以及点表和操作序列的BAS信息模型,基于此模型可以在建筑的全生命周期中使BAS模型在符合IFC标准的前提下保持单向传递性,利用创建出的模型可以直接使用能耗仿真及维修管理系统等的应用程序,并且能在调试和使用过程中直接从中提取各自所需的数据信息。

Using the language of EXPRESS-G in the design process of BAS to reduce duplication of effort, simplify the design process and reduce costs in design and construction based on the design of CAD and typical BAS. Building the information model of BAS which contains a list of devices, network topology, the list of points and the sequence of operating,the model can maintain one-way transfer when under the premise of the IFC standards through the building lifecycle to use the applications of energy simulation and management systems and so on, and it will also allow different people to extract information what they need by different kinds of software in the process of debug and use.
