1引言随着计算机、爱信、控制和图形显示技术,即4C技术的快速发展和全球对信息高速公路的大力建设,智能建筑这个数字化、网络化和信息化的结合产物开始进入人们的视野。然而,如今智能建筑内各种控制功能日益强大而复杂,致使同一建筑物内使用了不同厂商生产的设备。虽然业内开发了不同的楼宇自动化控制网络数据通信协议ModBus、OPC、LonWorks、BACnet和M-Bus等,但是这些通信协议都是针对
1 INTRODUCTION With the rapid development of computer technology, love letter, control and graphic display technology, that is, the rapid development of 4C technology and the global construction of information superhighway, the combination of digitalization, networking and informationization of smart building has begun to enter the field of vision. However, the various control functions in smart buildings are becoming increasingly powerful and complex, resulting in the use of equipment manufactured by different manufacturers within the same building. Although the industry has developed different building automation control network data communication protocols ModBus, OPC, LonWorks, BACnet and M-Bus, but these communication protocols are for
