摘要
本文讨论用EIA RS-232C串行接口作为通讯线路,并选用国际链路层通讯协议HDLC进行FMS中主机与CNC系统的通讯。为了适合FMS中的应用,对该协议进行了一定的扩充,还对它进行了Petri网的造型和分析,证明了它的可行性。
In dealing with the communication between host computer and CNC system in FMS, EIA RS-232C serial interface and HDLC data link are used. For application in FMS, certain expansions are made to the protocal and the modelling of petri net and analysis are given to prove the feasibility of this protocal.
