摘　　要：叶片过滤机是精炼车间脱色工段中非常关键的设备,设备前端后续的工艺阀门很多,有很多操作步骤和时间节点控制阀门的开启和关闭,操作复杂烦琐。为简化人工手动操作的烦琐性及为更多单机系统控制提供技术参考,以立式叶片过滤机为例,采用PLC和触摸屏的方式构建自动控制系统,控制叶片过滤机的单机运行和切换控制。自动控制系统的CPU采用西门子S7-1214C DC/DC/Rly,HMI采用西门子KTP1200触摸屏,并采用西门子TIAPORTALV18软件进行PLC硬件组态及编程和上位机KTP1200的监控和控制界面的制作,自动控制系统的设计包括两台过滤机的单独控制和切换控制,可根据不同的产量设定切换的时间参数。此系统运行稳定可靠,是独立的控制系统,可以单独应用于生产,还具有以太网通信功能,可以实现与其他控制系统的数据交换。The vane filter is a very critical equipment in the decolorization section of the refining workshop,there are many process valves at the front end and follow-up of the equipment,there are many operation steps and time nodes to control the opening and closing of the valve,and the operation is complex and cumbersome.In order to simplify the tediousness of manual operation and provide technical reference for the control of more stand-alone systems,taking the vertical vane filter as an example,PLC and touch screen were used to build an automatic control system to control the stand-alone operation and switching control of the vane filter.The CPU of automatic control system adopted Siemens 1200 series S7-1214C DC/DC/Rly,HMI adopted Siemens lean series touch screen KTP1200,and Siemens TIA PORTAL V18 software was used for hardware configuration and programming,and the production of monitoring and control interface of host computer KTP1200.The design of the automatic control system includes separate control and switching control of the two sets of filters,and the time parameter of switching can be set according to different outputs.This system operates stably and reliably,and is an independent control system,which can be applied to production alone,also the system has Ethernet communication function,therefore can realize data exchange with other control systems.
