基于ARM9和嵌入式Linux的BACnet楼宇控制器的研究

应用BACnet/IP技术的楼宇控制器,楼宇控制中心通过以太网高速连接位于不同楼层、不同功能的应用控制器。通过ARM9的硬件平台设计出硬件的各个功能模块电路,通过移植嵌入式Linux系统,为控制器提供了软件的稳定运行环境、网络环境。重点完成了BACnet协议栈,通过协议栈,控制器与其他BACnet设备进行数据交换。提出了控制器在具体工程中的应用方法。

Research on BACnet Building Controller Based on ARM9 and Embedded Linux

Application of BACnet/IP technology building controller, building control center via high-speed Ethernet connec- tions in different floors, the application of different functional controller. In hardware, from the cost, performance and other aspects identified ARM9 hardware platform, according to the system need to design the various functional modules of hard- ware circuit; in software, embedded Linux system by transplantation, the controller provides a stable operating environment software and network environment. This paper focuses on the completion of the use of C language realization BACnet protocol stack, through the protocol stack, the controller with other BACnet devices for data exchange functions, proposes the application methods of controller in practical projects.
