基于CAN总线的智能小区通信控制器的设计

智能小区的宗旨就是将结构、系统、服务与运营结合并优化组合，现场总线技术是智能小区的重要应用技术之一，而CAN（控制器区域网）总线与一般总线相比，它的数据通信具有突出的可靠性、实时性和灵活性，并且受干扰的概率低。文中针对智能小区的管理中心与小区各系统要实现自动化的监控与管理，设计了一种基于CAN总线的通信控制器。介绍了该设计的硬件电路结构、原理及软件结构和主程序流程。应用结果表明该设计方案具有硬件简单、适应性和可扩展性强的特点，并且现场调试简单，缩短了开发周期。

Design of Intelligent Housing Communication Controller Based on CAN Bus

The purpose of intelligent housing is to make the structure, system, service and operation combined and optimized. CAN bus is one of the most important technology applied to the intelligent housing. Compared to other buses, its data communication has high reliability, real-time ability and agility and has low- er interference probability. In this paper a communication controller based on CAN bus is designed, and the purpose is to have monitoring of the management center and every system of the housing. The hard circuit structure, its operation principle, software and flow of host program are also introduced. The result shows that the design has simple hardware, powerful adaptability and expansibility, and simple debugging, wihch shortens the development period.
