Research To Integration Ways Of Building Automation System

With the development of the Intelligent Buildings, the number of the subsystem of the Building Automation Syetem is also increasing rapidly. Due to the various subsystems from different manufacturers, they use different technology and operating platform, it results in information of various systems can not be shared, and equipment and human power wastes.The Integration of Building Automation System is a flat connecting sub-systems with different technology and fuction. Because the flat can be operated and managed easily,the benefit can be achieved such as improving efficiency ,decreasing cost and saving resource.There are some ways of Building Automation System Integration, from hard-line connecting relays mode in early time, to communication mode by serial ports, to gateways mode and LonWorks,BACnet,DDE,OPC in recent years. As a result ,It seems that engineers have a very wide range of alternative methods. However,most of ways have limitions from equipment vendors who limits integrationg technology considering commercial benefit.In this paper,several ways of System Integration is involved,the concept and development of BAS and System Integration is introduced in first chapter,the distinction between Building Automation Management System Integration(BMS) and Integration Building Management System Integration(IBMS) and accomplishment ways is clarified in chapterâ…¡,the integration ways with OPC technology interface is an emphasis,and difference on achievement,connection and communication protocol between various integrated ways is mentioned in chapterâ…¢. In Chaptersâ…£andâ…¤, the author design a practical and highly efficient building automation systems integration system for the Client by using different interface and protocol technology including Serial communication, Socket protocol, ODBC relational databases, TCP / IP, Ethernet, OPC Data Access and OPV Alarm/Event protocol.
