PLC在自动加料和称量控制系统中的应用

本文介绍了鼓风炉加料计算机控制系统的组成和工作原理以及备料漏斗秤的工作原理。该控制系统主要采用了以美国MODICON公司生产的984PLC主机为控制核心,大屏幕彩包监视器、编程器、位置控制装置、终端操作台等硬件设备作为配套的一个集逻辑控制、数模转换、报表统计管理于一体的过程控制系统。该计算机控制系统有效地实现了鼓风炉自动化,降低操作人员的劳动强度,提高了生产效率。

The PLC Application in Automatical Supplying Materials and Controlling Measure System

This paper describes the computer control system constitutes and their work principle of blast furnace and stock funnel steelyard in our second plant.It regards primarily the 984PLC host produced by the united states MODICON company as the control kernel.This process control system contains the logic controlling,the mathematic mode converter,the report statistical managing.it's hardware equipments include the big colorful monitor,the programmable machine,the position control equip and the terminal device.The compute control system carried out blast furnace automation availably,lowering labor strength of the operators,raising production efficiency.
