摘　　要：针对某钢铁公司热轧板厂的热连轧主传动系统,设计开发了一套基于RS485总线与工业以太网的网络分布式设备状态监测与故障诊断系统。研究了网络化系统的结构、组成。解决了网络化系统中带RS485接口智能数据采集模块的通信,服务器、客户端、LED显示屏等通过以太网的通信,可编程控制器(PLC)和服务器构成的点对点的通信问题。实现了热连轧主传动系统24个径向跳动点和12个轴向窜动点实时信号的同步采集和数据库存储。该系统在现场运行良好,为轧机急停、传动跳闸及提高板材质量提供了可靠依据。A new distributed equipment condition monitoring and fault diagnosis network system based on an RS485 field bus and an industrial ethernet was designed for the main drive system of a hot.strip mill. The system structure and composition were studied. The following problems were resolved： communication of an intelligence data acquisition module with RS485 interface; communication between a server, clients and a light emitting diode; and point to point communication between a programmable logic controller and server. Real-time signals of 24 radial run-out, 12 axial drifting can be synchronously acquisitioned and stored in a database. System operation is satisfactory and can be used to identify the causes of rolling mill halt and transmission slip brake, and to improve sheet metal quality.
