LIN总线技术在汽车中央集控门锁上的应用

Applications of LIN Bus Technology in Automobile Central-Controlled Gate Lock

介绍了LIN总线的基本特点,设计了基于LIN总线技术的汽车中央集控门锁控制系统。该系统综合考虑汽车在特殊环境下的工作性能,根据LIN协议建立了通信网络。采用以P87LPC769单片机与TJA1020LIN收发器为硬件核心,开发设计了智能化主节点和从节点,完成了主从节点的电路设计。

Basic features of LIN bus are introduced in this paper; the automobile central-controlled gate lock system based on LIN bus is designed. Taking into account the working performances of car in special condition, the communication network is established according to LIN protocol. Also adopting the technique of hardware component transceiver of TJA1020-LIN and P87LPC769 as the kernel, the intelligence master and slave node are developed and the design of master circuit is completed.
