摘　　要：基于LocalInterconnectNetwork(LIN)汽车总线技术,在DP-51H单片机数据通信综合仿真实验仪上提供一个实现LIN-bus通讯网络软硬件调试/仿真的环境,综合考虑汽车在特殊环境下的工作性能,研制了基于LIN协议的汽车车灯控制系统.该系统根据LIN协议开发设计了智能化主节点和从节点,完成了主从节点的硬件选型和电路设计以及软件分析和程序实现.在车灯系统的设计中,节点间的LIN通讯完全符合LIN1.2规范协议,该协议基于通用的UART/SCI硬件接口,采用ISO9141单线传输标准,采取单主多从的总线型拓扑结构并提供方便的用户应用编程接口.Based on Local Interconnect Network (LIN) car bus technology, in DP-51H MCU data communications integration imitation experiment instrument, provided a network soft and hardware debugging and emulation condition to implement LIN-bus communications, taked into account car performances of work in special condition, development of a car light control system based on LIN-bus, according to LIN protocol, designed and developed intelligence master and slave node. We completed hardware component selection and designed of master circuit. Software analysis and procedure realization. In the design of the light system, the communication of LIN bus is according to the norm of LIN1.2 completely. The LIN interface is based on the standard UART/SCI. It adopt to the single line standard of ISO9141, the LIN network consists of single master node and multiple slave node concept, provided the convenient user API.
