|Abstract: ||Building automation systems (BAS) are transforming from the legacy stand-alone security and safety systems to intelligent computerized network based solutions. This paper presents the design of a three-layer BAS for a residential building. Sensors and MODBUS compliant digital I/O DAQ modules are wired to form an RS-485 network at field level, that are connected to a PC based main controller. The design incorporates central servers for-(i) OLE for Process Control (OPC), (ii) Camera, (iii) Graphical User Interfaces (GUIs) and (iv) Entertainment. A local or remote workstation working as a client can access all functionalities using intranet or internet respectively. RS-485 network is used for the time-critical process-alarm data exchange, and Ethernet backbone is used for high speed Client-Server communication.
Various functionalities of the BAS have been validated through laboratory implementation.|
