CAN总线技术在汽车视觉检测系统中的应用

摘要

The research and application on CAN and multi-host control system in autocar-body visual　inspection is presented.The multi-host distributed control system using Motorola MC68HC05X16 and PC as the host controller is proposed.The topology of the network,the physical interface and the relevant hardware are introduced.Meanwhile,a minute research on communication protocol and the disciplinary are performed.%根据汽车白车身视觉检测站工作的特点和需要，对基于CAN总线的多主结构分布控制系统进行了研究，并组建了基于MC68HC05X16单片机和微机的控制网络。文中对CAN总线物理层接口、拓扑结构、通信协议及规程等作了详细说明。
