摘要: 对比分析了目前2种BACnet(楼宇自动控制网络数据通信协议)与Internet的互联技术,即B/IP PAD(BACnet/Internet协议包封装/拆装设备)和BACnet/IP,并指出了这2种技术所存在的问题.提出了一种基于BACnet网关的互联模型,此网关工作在BACnet网络层,需要配置一个独立的IP地址和一个BACnet网络号,同时也必须维护一个对等网关的IP地址与BACnet网络号的本地数据库.该模型通过BACnet网关来完成不同协议之间的语义转换、广播及管理等功能,为BACnet网络与Internet之间提供了统一的网络接口,增强了楼宇控制网络与Internet融合的能力,并大大简化了BACnet网络与Internet的互联过程.在研究此模型的体系结构和工作流程的基础上探讨了该模型的实现方法.

Abstract: The comparison and analysis of two current interconnection technologies between a data communication protocol for building automation and control network(BACnet) and Internet, including BACnet/internet protocol packet-assembler-disassembler(B/IP PAD) and BACnet/IP, was carried out. The existing questions of two technologies were pointed out. The interconnection model based on BACnet gateway was presented. The gateway works at BACnet network layer. The gateway need configure an isolated IP address and a BACnet network ID. The gateway must maintain a local database including IP addresses and BACnet network IDs of peer-to-peer gateways. The functions of BACnet gateway consist of semantic transformation, broadcast and management of different protocols. A uniform network interface between BACnet and Internet was provided by the model. The convergence capacity of the building control network and Internet was enhanced. The interconnection process between BACnet network and Internet was greatly simplified. Based on the research of the model’s architecture and workflow, the implementation approach of the model was discussed.
