摘　　要：介绍了一种以微处理器PIC18F2480为核心的CAN总线和485协议及PLC自由口通讯在索道运行安全回路中的应用。文章用自上而下的层次化设计方法对系统进行实现,主要包括系统总体设计,CAN总线硬件设计、软件设计及上位机自由口通讯。在实际应用中效果良好,并且具有布线简单、可长距离通讯、维护方便、部件互换性好、可靠性高等优点,填补了国内外CAN总线在索道应用中的空白。This paper introduces a kind of CAN bus, 485 protocol which regards microprocessor PIC18F2480 as the core and PLC free - port communication in application of the ropeway operation safety circuits. It is used a top- down and hierarchical design method to implement the system, mainly includes overall design of system, hardware ,software design of CAN bus and host computer freeport communication. It leads good results in practical applications, and it has advantage of wiring simple ,being able to long distance communication,easy maintenance,good art interchangeability and high reliability. It has filled a blank in and outside of our country in ropeway application of using the CAN bus.
