毕业设计（论文）任务书 课题名称： PLC控制系统设计－锅炉输煤系统 PLC控制系统设计——锅炉输煤系统 PLC控制系统设计——锅炉输煤系统 摘 要 本文介绍的是用PLC来对锅炉输煤系统进行控制。锅炉输煤系统，是指从卸煤开始，一直到将合格的煤块送到煤仓的整个工艺过程，它包括以下几个主要环节：卸煤生产线、煤场、输煤系统、破碎与筛分、配煤系统以及一些辅助生产环节。he System of Transport Coal in Boiler Abstract This paper design for the boiler which is beaten the coal measures together with PLC . The transportation system of coal in boiler is that beginning with unload coal from car, and until to warehouse. The system includes several chief segments: coal does unload manufacture part, coal warehouse, transportation system of coal, fragmentation coal, sift through and other supplementary system. The transportation system of coal is the chief part of this design. In other words is that a course from the machine of supply coal to the warehouse of coal. We chose the method of sequential control in the system. First, the paper tells us some fundamental general knowledge problems of PLC and the fundamental means and step in this design. The type detailed to introduce some fundamental in formations of the PLC of S7-200 of the siemens corporation. Then we can know some problem about PLC programming s start, stop and output alarm, and also say that I/O touches some matters distributing has been underway the address assignment allocation to the target in native design . In ordinate engine design , I use the industry configuration , and software - configuration monarch comes to manipulate interface manufacturing , and cause it carry on the news dispatch against PLC , causing it attain the remote control meritorious service capacity , move and means manufacturing the operation interface are stress give an account of once more to the middle . Keywords: the system of transport coal in boiler, PLC, I/O, Kingviews 目录 1 绪论 10 1.1 锅炉系统概述 10 1.2 锅炉输煤系统 10 2 可编程控制器(PLC) 11 2.1 可编程控制器(PLC)简介 11 2.1.1 PLC的历史 11 2.1.2 PLC的基本概念 11 2.1.3 PLC的基本机构 12 2.1.4 PLC的扫描工作方式 12 2.1.5 PLC的I/O模块 14 2.1.6 PLC的功能及特点 14 2.1.7 PLC的分类 15 2.1.8 PLC的通信联网 16 2.2 PLC控制系统
