摘　　要：介绍了多台基于DSP智能保护装置与PC机之间通过CAN总线和以太网技术实现高速远距离通信的方法。该系统充分利用了PC机的容量大、人-机界面友好、DSP芯片速度快、实时性强、以太网的标准性和开放性、CAN总线的通信速率高可靠性强等优点,从而很好地实现了管理监控层和生产测控层之间的连接,大大提高了整个系统的性能。The paper introduced a realization method of high speed and distance Communication between PC and the intelligent protection devices by CANbus and Ethernet. The given system made full use of high speed and real time of DSP,the large capability of PC, standard and public character of Ethernet and high speed of communication and dependable nature of CANbus. Realize intercommunion between production monitoring layer and upper managing layer and enhance the overall performance of the whole integrate system greatly.
