摘要
这里为某车型基于LIN总线的车身控制系统设计实现了一款车身控制器,给出了以车身控制器为主节点的车身LIN网络架构,在深入研究LIN协议及LIN网络通信机制的基础上,描述了LIN网络通讯行为模型及主节点在LIN网通信调度中的作用。结合LIN主节点的设计,介绍了数据链路层协议规范及其设计技术,并通过分析LIN网通信调度和信号提取,介绍了应用层的实现,最后说明了网络管理功能的机制及其实现。
A car-body controller for a car body control system based on LIN bus is designed,the LIN network architecture with car-body controller as the master node is given.Based on in-depth study of network protocols and LIN communication mechanism,this paper describes the behavior model of LIN network communication and the role of master node in the LIN network communication scheduling.In combining the design of LIN master node,this paper discusses the specification and its design technology of the data link layer,through the analysis of LIN network communication scheduling and signal extraction,treats of the application layer implementation,and finally tells of described the mechanism of network management function and its realization.
