摘　　要：针对目前工业领域应用较广的两种现场总线CAN和PROFIBUS通信协议互不相容的问题,分别对其帧结构及数据传输方式进行研究,提出一种基于STM32的CAN-PROFIBUS协议转换器的设计,并在此基础上,增加了冗余电源电路和存储电路,保证系统稳定可靠工作的同时还具有数据暂存和断点重发功能。Aiming at the problem of two kinds of widely used industrial field bus CAN and PROFIBUS communication protocol being in compatible, frame structure and data transmission mode are studied respectively. A kind of CAN-PROFIBUS protocol conversion meth od based on STM32 is proposed, and the redundant power circuit and memory chip are added to ensure that the system is stable and reli able with functions of data storage and breakpoints.
