基于行业基础类（IFC）和楼宇自控网络协议（BACnet）的建筑信息模型（BIM）， 楼宇自控系统(BAS)及物联网（IoT）数据的信息交互方法研究及其应用

建筑信息模型（BIM）、智慧建筑中的楼宇自控系统（BAS）和物联网(IoT)设备传感技术是未来智慧建筑环境和绿色建筑发展的关键技术。由于操作系统、应用流程、数据模型的不同，BIM、BAS、IoT技术中大量的信息孤岛及多元化的数据模型引发了数据互操作性的问题。本项目旨在研究基于IFC标准的BIM建筑构件信息、符合BACnet协议的BAS信息及IoT时序数据三方信息交互的方法及应用，包括：1）开发基于BACnet协议的BAS设计信息与基于IFC标准的BIM建筑构件信息的交互方法；2）开发包含BACnet信息的BAS元数据与BIM建筑构件信息的交互方法； 3）开发IoT时序数据与BIM及BAS信息交互方法及应用。本项目的研究成果将基于行业广泛应用数据模型，采用语义网技术解决BIM、BAS、IoT三大数字技术中信息交互的障碍，进一步促进未来智慧建筑环境与绿色建筑应用创新与跨领域的信息交互。

Building Information Modeling (BIM), Building Automation System (BAS), and Internet of Things (IoT) device sensing technologies are the keys for the future development of smart built environments and green buildings. However, the data generated by BIM, BAS, and IoT technologies origins from different software, various process applications and are represented using multiple data models, forming isolated data silos. The isolated data silos and diversified data models in BIM, BAS, and IoT technologies cause data interoperability problems and obstacles to information exchange. This research aims to study the method and application of tripartite information exchange between IFC-based BIM building contextual information, BAS information conforming to BACnet protocol, and IoT time-series data. The main research objectives are: 1) develop information exchange method between BAS design information based on BACnet protocol and BIM building contextual information based on IFC standard; 2) Develop an information exchange method between BAS metadata containing BACnet information and BIM building contextual information; 3) Develop IoT time-series data, BIM, and BAS triparty information exchange methods and applications. The research outcomes will solve the data interoperability issue between BIM, BAS, and IoT based on widely adopted industry data standards, thus, unlocking the potential of future smart built environment and green building innovations.
