基于CAN总线的门禁读卡控制器设计

The design of the access control card reader based on CAN bus

CAN总线是一种有效支持分布式控制和实时控制的现场总线控制网络。该文介绍了CAN总线在门禁系统中的应用设计,给出了门禁系统的整体结构和基于CAN总线的门禁读卡控制器的总体结构,着重介绍了读卡控制器的软硬件设计。

CAN bus is a kind of field bus control network which can effectively support distributed control and real- time control. This paper introduce the application design of CAN bus in the entrance guard system,gives the overall structure of the access control system and the overall structure of the access control card reader based on CAN bus,and mainly introduces the design of the hardware and software of the card reader.
