Abstract

BACnet protocol with the characteristics of openness, practical and easy integration with other networks is widely used in building automation control system(BACS). In order to make the BACnet building automation control system exchange data with third-part software, an integration scheme of BACnet building control system based on OPC technology is designed. Implementing that BACnetMS/TP collects real-time data from building automation equipment and transform it into the OPC standard data type, completing the OPC interface call, so as to satisfy the requirement of the building control system integration. Through factory soft testing, development of BACnet building control system based on OPC technology is feasible.
