摘　　要：针对传统单门密码控制器的不足,将CAN总线技术与红外编码遥控技术相结合,设计一种基于CAN总线智能门禁系统的单门控制器。整个控制器采用STC89C55单片机、外扩展的CAN控制器、数据存储器、实时时钟电路、键盘显示等电路,实现了遥控开锁、实时时钟显示、CAN数据通信与显示,键盘控制、密码修改与保存等功能。基于CAN总线技术的密钥管理功能,使得该控制器的可靠性、实时性更好。In view of the faults of the traditional single door-controller,a single door-controller based on intelligent door-entry system through CAN bus was designed via combining the CAN bus with infrared coded remote control technology. The controller consisted of STC89C55 single chip,CAN controller,data memorizer,the real time clock,and keyboard display circuit. It could realize the function of remote controlling-unlock,real-time clock display,CAN data communication,keyboard control,and password changing and saving.Based on the function of the key management technology of CAN bus,it made the controller highly reliable and real-time.
