摘要
计算机通信网络在工业自动化领域中的应用十分广泛。宝钢三期原料场控制系统采用以太网和Genius网组成的两级计算机通信网络，本文结合该控制系统的建设，简要介绍了IEEE802．3CSMA／CD以太网与IEEE802．5令牌环Genius网的主要技术指标，详细论述了两级计算机通信网络的工作原理、网络部件和系统构成。
Computer communication network is widely used in industrial automatic control area. The control system in Bao steel Third Phase Raw Material Yard (TPRMY ) takes use of Ethernet and Genius two - level computer communication network. Combined with the construction of it,this paper briefly introduces the main technological characteristic of IEEE 802. 3 CSMA/CD Ethernet and IEEE 802. 5 Token Ring Genius network,emphatically narrates the working principle,network components and system structure of the two level communication network in TPRMY control system.
