摘要
应用MIFARE射频技术,以NXP公司的LPC11C14 ARM微处理器为控制核心,设计了一种基于CAN总线的电梯门禁控制器。详细介绍了电梯门禁控制器的功能及组成,硬件设计和IC卡读写的软件设计。在分析LPC11C14的CAN控制器工作原理的基础上,设计了门禁控制器与电梯轿内控制板之间进行数据交换的CAN通信协议,实现了对电梯使用权限的控制。
An elevator access controller based on CAN bus is designed, which adopts ARM microprocessor LPCllCI4 from NXP Company as the contro! core and applies the MIFARE radio frequency technique to realize the function. The paper describes in detail the function and composition Of the elevator access controller, the hardware design and the software design of the read-write to IC cards. On the basis of analyzing the working principle of CAN controller, which is in the LPCllC14 the paper designs the communication proto6ol tO proceed in data exchange between the elevator access controller and the elevator car controller, and the control of elevator permission is realized.
