Design And Realization Of System Integration Management Software With The BACnet Technology

With the continuous development of various techniques in the field of intelligence construction, more and more technological standards have been proposed, and problems such as disunity of standards and failure to operate equipments mutually made by different manufacturers also arise. Serving as the sole international standard of building automatic control field, BACnet protocol can be applied to solve these problems by integrating controlling products of different brands in one system thus can provide the maximum system agility and cost high efficiency for both owners and managerial personnel. Based on the research and development work of intelligence construction system integration management model software with the basis of BACnet/IP technology, the paper discusses the design and implementation of the model software by using Java language and SQLServer2000 data base as development platform.Beginning with the principles of BACnet protocol, the paper analyzes the principle and advantages of BACnet in details, analyzes how to carry out intelligence building system integration by using BACnet protocol and builds the development construction of intelligence building system integration management software with Java language as basis and SQLServer2000 data base served as development platform, BACnet protocol served as network communication protocol. First, the author makes detailed analysis and studies on BACnet protocol, develops and designs basic class libraries codes of BACnet protocol based on Java language according to BACnet protocol demands; then carefully studies BACnet/IP technology, develops network communication module based on BACnet/IP as network communication protocol ; and implements other functional modules such as data base interface, accomplishes intelligence building system integration management software based on BACnet/IP protocol.The design and implementation of this software plays a very important role in popularizing BACnet protocol in China and in realizing the popularization of intelligence building system integration management. Especially the development and design of BACnet protocol basic class libraries based on Java language have laid a good foundation for futher development in the future.
