| Abstract: | One of the important techniques in distributed numerical control (DNC) system is the interconnection and communication of the computers. This paper discusses a choice of the fieldbus architecture of DNC system, presents the hardware and software architecture and characteristics of the system. and much more attention is paid to the emergence and settlement of the bus collision. The collision of information transfer is settled in the software design of the system with the method of CSMA-CD/OB. |
