摘　　要：某酸轧产线改造轧机支撑辊、中间辊和工作辊的轴承润滑方式,由稀油润滑改为油气润滑。油气润滑控制系统为独立系统,采用Siemens S7-315系列PLC作为控制器。为实现油气润滑系统关键信号参与轧机各机架的运行控制和监控油气润滑系统运行状态,基于产线TMEIC PLC硬件,设计了油气润滑远程控制系统。采用Profibus-DP通讯方式实现两个PLC之间的数据交换,通过增加油气润滑系统的主站和卫星站的运行状态监控程序、远程控制油气润滑系统程序和操作界面,实现了远程控制油气润滑系统的功能。The bearing lubrication mode of support roll,middle roll and work roll in acid rolling production line is changed from thin oil lubrication to oil-gas lubrication.The oil-gas lubrication control system is an independent system,using Siemens S7-315 series PLC as the controller.In order to realize the key signals of oil-gas lubrication system participating in the operation control of each stand and remote monitoring the status of oil-gas lubrication,the remote control system of oil-gas lubrication was designed based on TMEIC PLC hardware of production line.The Profibus-DP communication method is used to realize the data exchange between two PLC systems.By adding the program of the monitoring running status of the primary stations and the satellite stations in the oil-gas lubrication control system,the program of remote control oil-gas lubrication system and operation interface,the function of the remote control of oil-gas lubrication system is realized.
