摘 要
  PLC及其网络在工业自动化控制领域越来越受到重视和普及应用，它的应用提高了高炉上料系统的自动化水平、可靠性，实现了上料系统的实时监控和灵活方便的工艺配方。料车式高炉上料系统是一个多环节的复杂系统。过去，各环节分开单独操作，环节之间联系麻烦、上料效率低。现在，将高炉的上料系统改造成自动上料系统，大大的提高了高炉上料系统的工作效率，在工业领域也会受到普及。
本文主要对传统的高炉系统中存在的不足进行分析，设计了可编程序控制器控制的高炉自动上料系统，解决了传统高炉系统中各个操作环节之间联系麻烦，克服了在以往操作上的繁琐。高炉上料系统的设计主要考虑了传感器称重、料斗的下料、传送带的转动、料车的上行和下行等，使用PLC控制高炉的选料和送料，实现了高炉上料的自动化。
本文主要介绍了四个部分：第一章介绍了本课题研究的背景，高炉自动上料系统在现实生活中的应用，阐述了国内外高炉自动上料系统的研究现状；第二章介绍高炉自动上料系统的硬件部分，主要介绍了PLC和欧姆龙CPM2A；第三章介绍了高炉自动上料系统的软件部分，主要介绍了在高炉自动上料系统中PLC的程序设计；第四章介绍了世纪星组态软件，主要介绍了实时监控系统的设计、编写，动画的衔接以及上位机监控系统和下位机之间的通信。

Abstract
PLC and its network are receiving increasing attention and wider application in the field of industrial automation control,its application improved the blast furnace system automation level and reliability,realization of the feeding system for real-time monitoring and flexible formulation process.Feeding car-style blast furnace system is a complex system.Over the past,separately in every link of the operation make the links between segments so trouble and inefficient feeding.Now,we use the last blast furnace feed system into automatic feeding system so that the blast furnace system efficiency is greatly increased and it will be universal in the field of industry.
The article analyzed weaknesses of the traditional blast furnace system,designed a programmable logic controller to control the blast furnace automatic feeding system,to solve the links between the various operations of trouble in the traditional blast furnace system links,and overcome the cumbersome operation in the past. The design of blast furnace systems considered the weighing sensors,the hopper slooshing,conveyor belt rotation,uplink and downlink of feeding car.PLC controled the use of blast furnace of election material and feeding so as to realize the blast furnace automatically.
This paper introduced four parts:The first chapter described the background to the study of this topic,application of the blast automatic feeding system in the real-life, blast on the automatic feeding system for the present status around the world.Chapter II presented hardware of the blast automatic feeding system,introduced the PLC and CPM2A of OMRON.Chapter III introduced software of the blast furnace automatic feeding system,especially designing the programmer in the blast furnace automatic feeding system PLC.Chapter IV introduced Century Star configuration software, mainly introduced the design of real-time monitoring system,the convergence of animation and the communications between PC monitoring system and the field control apparatus.

Keywords: Automatic feeding systems;Century Star;Programmable Logical Controller
