【摘要】 智能建筑是信息技术在建筑领域中应用的必然结果,近年来得到了迅速的发展和普及,也日益得到社会广泛的认同和重视。近几年来,智能建筑市场也在迅猛发展,建筑智能化系统多达十几种。然而无论是智能大厦,还是智能小区都缺乏相应的国家标准,核心技术被国外的企业所掌握。BACnet标准作为楼宇自控领域中惟一的开放性国际标准,是我国楼宇自控领域与国际接轨和赶上国际先进水平的机遇和挑战。本文共有五章,从BACnet标准的研究入手,从最基本的数据类型的实现开始,详细叙述了协议的实现过程。BACnet标准的主要特点,包括体系结构、BACnet对象及其属性、BACnet服务和BACnet/IP技术,这些都是实现该标准的重要的组成部分和重要基础。根据BACnet标准协议栈编码的主要规则,按照BACnet标记编码,数据类型编码,应用层用户数据部分编码,应用层及其下各层控制信息部分编码的顺序,详细讲述了BACnet标准的具体实现工作。该标准的实现,是开发具有自主知识产权的楼宇自控设备的一个最重要的基础和前提。更多还原

【Abstract】 The Inte11igent building which is the inevitable result that the information technology is applied in the construction domain, in recent years, obtained the rapid development and the popularization. Also it obtains the social widespread approval and takes day by day. In the last few years, the intelligence building market mored forword quickly and there are tens of the building automatication system, however neither the intelligent building nor the intelligent plot has the national standard about this and what’s the most important is that the core technology is grasped by the overseas enterprises.The BACnet standard: A Data Communication Protocol for Building Automation and Control Networks, the only opening international standard in the buikding automation control area, gives us not only the opportunity but also the challenge to follow firstly and catch up lastly with the international advanced technique. This thesis is made up of five chapters, emphasizing the research of the BACnet protocol, staring from the realization of the most basic data types, carefully discusses the process of the protocol realization. Some of the most important features of the BACnet, including the system architecture, the BACnet object and its property, the BACnet service and the technique of the BACnet/IP, are the most important components and the most important basement of the realization of the BACnet protocol. With the rule of the protocol encoding, the process of the realization of the BACnet protocol is carefully discussed by the sequence of BACnet tag encoding, data type encoding, application layer user data encoding, application layer and the other layers under it control information encoding. This realization of that standard, is the most important foundation and the premise of the development of the building automatic control equipments that have the independent intellectual property rights.更多还原
