摘　　要：介绍CAN总线的应用前景,分析了传统的CAN总线电缆传输方式以及CAN总线光纤透明传输方式的弊端,提出了基于LPC2129单片机微处理器的CAN总线光纤传输方式,用于彻底解决CAN总线传输领域信号速率与传输距离的矛盾,实现CAN总线的远距离传输。The article introduced the application prospects of CAN bus,Analized the abuse of the way which used cable to transmit CAN bus and the way of Transparent transmission by using optical communication.This paper put forward a new method of CAN bus transmission based on MCU LPC2129,which can solve the contradiction between rate and distance in CAN bus,that can extend the transmission distance of CAN bus.

关 键 词：CAN总线 透明传输 协议转换 远距离
