一种基于CAN总线的DNC系统通信研究

INVESTIGATION OF COMMUNICATION FOR DNC SYSTEM BASED ON FIELDBUS

通信是DNC系统的关键技术之一,是设备集成和信息集成的基础.在分析了现有的DNC通信方式后,指出基于CAN总线的DNC系统通信具有实时性好,可靠性高,速率快等优点,是现阶段DNC系统通信的理想方式,并论述了其实现过程.

Communication is one of the key technologies in the DNC system, and also the foundations of the equipment integration and information integration. After analysing the existeat way of DNC communication, this paper points out that the communication of DNC system based on CAN bus is the ideal way of communication of DNC system at the present stage, for it has a real\|time character with high reliability, and high speed. Its course of realization is also described.
