与传统的RS-232总线相比，CAN总线是一个高速、长距离、多主、经济的网络系统，特别适用于实时系统。其易用性和低成本使得CAN在汽车工业和自动化领域得到广泛的应用。因此设计高性能的RS-232与CAN总线的接口卡以代替传统的PC机的RS-232总线通信具有重要意义。本文主要介绍了CAN总线的工作原理和RS-232与CAN接口卡的软硬件设计过程及注意事项。

Compared with the conventional RS-232 bus,the Controller AreaNetwork(CAN) is a high speed,long distance,multi-master and cost effective network system especially suitable for real-time control system.Its ease of use and low cost have led to its wide adoption throughout the automotive industry and automation fields.So it is useful to design a RS-232-CAN interface card to replace the conventional RS-232 bus.Some ways into explaining how to develop a RS-232-CAN interface card and the working mechanism of Controller Area Network(CAN) are given.
