CAN與RS232轉換節點的設計與實現
介紹將CAN總線接口與RS232總線接口相互轉換的設計方法和2種總線電平轉換關系，實現CAN總線與各模塊的接口設計，制定了相應的軟硬件設計方案，并給出軟件設計流程圖以及部分硬件設計原理圖。為CAN總線與RS232總線互聯提供了一種方法，對CAN總線與RS232總線接口設備的互聯和廣泛應用的實現具有重要意義。關鍵詞：CAN總線；RS-232總線；串行通信Design and Realization of CAN and RS232 Transformation NodeZHOU Wei, CHENG Xiao-hong(Information Institute, Wuhan University of Technology, Wuhan 430070)【Abstract】This paper introduces one design method of the CAN bus interface and the RS232 bus interface interconversion, emphasizes two kindof bus level transformation relations, realizes the CAN bus and various modules connection design, formulates the design proposal of correspondingsoftware and hardware, and gives the flow chart of software design as well as the partial schematic diagram of hardware design. It providesonemethod for the CAN bus and the RS232 bus interconnection, has the vital signifiCANce to widespread application realization of the CAN busand theRS232 bus interface equipment interconnection.【Key words】CAN bus; RS-232 bus; serial communication
