CAN與RS232轉(zhuǎn)換節(jié)點的設(shè)計與實現(xiàn)
介紹將CAN總線接口與RS232總線接口相互轉(zhuǎn)換的設(shè)計方法和2種總線電平轉(zhuǎn)換關(guān)系，實現(xiàn)CAN總線與各模塊的接口設(shè)計，制定了相應(yīng)的軟硬件設(shè)計方案，并給出軟件設(shè)計流程圖以及部分硬件設(shè)計原理圖。為CAN總線與RS232總線互聯(lián)提供了一種方法，對CAN總線與RS232總線接口設(shè)備的互聯(lián)和廣泛應(yīng)用的實現(xiàn)具有重要意義。關(guān)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
