IBM/PC—YEWPACK计算机网络的设计

Design of IBM/PC—YEWPACK Computer Network Communication

论述了由YEWPACK计算机组成的工业过程集散控制系统及该系统与IBM/PC上位计算机组成网络的方法;用UGWU通讯适配器进行通讯的设计方法,参数选择以及通讯软件框图,据此为辽河油田油气处200万轻烃厂设计了异构机种的通讯网络,经调试表明设计方法正确,技术先进,能完成用户提出的要求,对同类网络设计具有普遍意义。

In this paper, an industry process centralizing—distributing control system consisting of YEWPACKcomputers is described. The connecting method of its ring network (LAN) with IBM/PC through gateway, and the designing method of communication by using a UGWU—2 adapter, choice of parameters, block of communication software are also presented.Based on the system above, a communication network for 2 Million Light Hydrocarbon Recollecting Factory in Liaohe Oil Field is designed. The adjustment result shows the correctness of the designing method and the advantages of the technique, which meets the users requirements. This can be widely applied in the design of networks of the same kind.
