摘要
分析了现场总线体系结构、CAN总线技术标准及通讯协议.利用CAN总线和单片机技术设计了车载计算机系统.给出了系统的软、硬件实现方案.软件采用模块化设计,包括主控端、采集、显示及通讯模块;硬件采用多主机并行设计,上位机负责通讯,下位机负责数据采集.
The field bus system structure and the CAN bus technical standard have been analyzed,the CAN agreement stratification structure,the physical level and the data link layer communication mechanism,the frame form and the text of a telegram filter technology have been introduced.We have adopted the computer system using the CAN bus and the monolithic integrated circuit technical design vehicle,produced the system to be soft,the hardware realization plan.
