近几年随着LIN总线技术的出现,由于其成本低廉,且采用可有效保证通信负载的一主多从结构,在通信速率要求不太高的车身电子领域,可以部分替代低速CAN总线。笔者结合所研制的车灯LIN网,介绍了系统结构及硬件设计关键技术,以及相关应用协议的实现。 In recent years, with the advent of LIN bus technology, due to its low cost and the adoption of a master-slave architecture that can effectively guarantee the communication load, the low-speed CAN bus can be partially replaced in the field of body electronics with less demanding communication rates. The author combines the LIN network developed by the lights, introduced the system architecture and hardware design of key technologies, as well as the realization of the relevant application protocol.
