CAN-bus(controller area network bus)is a field bus which is widely used in industrial control. As a microcon-troller,AVR SCM and its applications are becoming more and more widespread. The design scheme of CAN-bus communication node is studied by means of the characteristic introduction of CAN-bus technology. The specific hardware design scheme and soft-ware processes are offered in this paper. compares The advantages and disadvantages in the aspects of communication distance, real-time performance,reliability and flexibility between CAN-bus and RS-485 bus. The specific application of CAN-bus technol-ogy in the railway station communication system is introduced. The practical application proves that the CAN-bus has a good practical value in the railway station communication system,which lays a solid foundation for the technological upgrade of the railway signaling system.
