摘 要
本文介紹了由可編程序控制器(簡稱PLC)控制的打包帶熱處理過程控制系統(tǒng)。它以西門子系列PLC中的S7-300為控制器，利用PLC軟件編程來控制打包帶的整個生產(chǎn)過程。本設(shè)計(jì)解決了生產(chǎn)過程中出現(xiàn)的斷帶且提高了鋼帶的韌性等。首先介紹了一下生產(chǎn)過程中a主要設(shè)備的作用及過程中所要解決的一些問題，然后是中低強(qiáng)度打包帶系統(tǒng)的研究，介紹了生產(chǎn)工藝流程和熱處理工藝，接著是中低強(qiáng)度打包帶控制系統(tǒng)的設(shè)計(jì)，簡單介紹了PLC的發(fā)展和特點(diǎn)以及PLC在生產(chǎn)中的具體設(shè)計(jì)原則，在確定了控制系統(tǒng)的檢測點(diǎn)后，詳細(xì)介紹了西門子S7-300的系統(tǒng)特性和硬件構(gòu)成，讓我們更為完整的了解了可編程控制器。最后是系統(tǒng)的部分軟件設(shè)計(jì)，畫出了系統(tǒng)爐溫控制程序流程圖后，對控制系統(tǒng)的軟件進(jìn)行了編程，接下來介紹了PLC控制柜的組裝、布線及調(diào)試。從各部分研究了設(shè)計(jì)之后，繪出可編程序控制器控制系統(tǒng)的電路圖，確定可編程序控制器控制系統(tǒng)的硬件設(shè)計(jì)，繼而建立流程圖，再根據(jù)流程圖編寫出程序，整體上完成設(shè)計(jì)。

Abstract
This article introduced (i.e. PLC) controls by the programmable controller hits the bandage heat treatment process control system. West of it in family household series PLC S7-300 is a controller, controls using the PLC software programming knits the bandage the entire production process. This design solved in the production process to appear breaks the belt also enhanced the steel belt toughly and so on. First introduced in the production process main equipment function and the process needs to solve some questions, then are the low intensity hit the bandage system the research, introduced the production technical process and the heat treatment craft, then are the low intensity hit the bandage control system the design, introduced simply the PLC development and the characteristic as well as PLC in the production concrete principle of design, after had determined the control system check point, introduced in detail the Siemens S7-300 system performance and the hardware constitution, let we more complete understanding programmable controller. Finally is the system partial software design, after has drawn the system furnace temperature control procedure flow chart, has carried on the programming to the control system software, met down introduced the PLC control cubicle assembly principle, the wiring and the debugging. Has studied the design after various parts, draws the programmable controller control system the circuit diagram, determined the programmable controller control system the hardware design, subsequently establishes the flow chart, again compiles the procedure according to the flow chart, and in the whole completes the design.
Key word: Programmable controller；Heat treatment ；Intermediate frequency stove； Thermo-element
