摘　　要：针对楼宇自动化系统(BAS),设计了以AT89S52单片机为核心的智能控制器。采用一体化结构,其内部集成了输入/输出模块,RS232/485接口以及可编程网关通信模块NE4100,可作为BAS中的一种通用区域控制器广泛用于电梯、照明、火灾报警等各个子系统中。网关模块采用基于Modbus和TCP协议的串口通信方式,通过互联网实现区域控制器与中央管理系统的通信。设计全面兼容Modbus工业标准,数据传输可靠,响应速度快,扩展灵活,实现了楼宇的智能化、网络化管理。For building automation system （BAS）, a new intelligent controller is designed, which employs single chip micro-computer AT89S52 as the kernel, integrates input/output module, RS232/485 interface and programmable gateway NE4100 communication module inside. The controller can be widely used in every subsystem in BAS, such as elevator, illumination, fire monitoring and so on. By using serial communication based on Modbus and TCP protocols, the gateway module is responsible for the communication between controller and its supervisory computer through Intemet. Being compatible with Modbus industrial standards, reliable in data transmission, quick to response and flexible to extension, the intelligent, network management on BAS is achieved.
