摘  要

 當(dāng)前國(guó)內(nèi)成熟的食品加工生產(chǎn)控制系統(tǒng)一般是由人工操作或由工控機(jī)、操作臺(tái)及配電柜幾部分組成，雖然該系統(tǒng)能滿足控制系統(tǒng)的工藝要求，但具有體積大、可靠性低、修改困難的缺點(diǎn)。基于這些缺點(diǎn)及PLC控制技術(shù)飛速發(fā)展的背景，本文提出了“PLC+觸摸屏”這樣一種既經(jīng)濟(jì)又可靠的食品加工生產(chǎn)控制系統(tǒng)方案，并詳細(xì)分析了這種控制系統(tǒng)的需求，根據(jù)需求，對(duì)系統(tǒng)的軟、硬件結(jié)構(gòu)進(jìn)行系統(tǒng)而全面的分析與設(shè)計(jì)。
 首先，論文給出了選題的背景及意義，并給出了本論文需要完成的主要工作；接著分析了控制系統(tǒng)的控制流程、工藝要求通過(guò)分析給出了的總體設(shè)計(jì)方案；其次，論文對(duì)控制系統(tǒng)特征進(jìn)行分析，結(jié)合生產(chǎn)線的控制要求，設(shè)計(jì)出系統(tǒng)的硬件原理框圖；最后，論文對(duì)程序流程和友好的人機(jī)交互界面設(shè)計(jì)進(jìn)行全面的論述，在屏幕上可以看到控制流程步驟的顯示。通過(guò)模擬調(diào)試表明控制系統(tǒng)的設(shè)計(jì)是正確有效的。
 本課題研究成功，可以大大提高生產(chǎn)效率，節(jié)約勞動(dòng)力，以滿足市場(chǎng)的需求。

 Abstract

 Currently，the domestic food processing production control system are carried out by manual operation or by the industrial computer, console and distribution cabinet consists of several. Although the system can meet the process control system, but has the shortcomings of a bulky, low reliability, difficult to amend. PLC-based control of these defects and the background of the rapid development of technology, In this paper, the "PLC + touch screen," such an economical and reliable control system for food processing production program, and a detailed analysis of the demand for such a control system, according to the needs of the system software and hardware structure of systematic and comprehensive analysis and design.
 First of all, the discourse gives the background and significance of topics, and gives the discourse the main work to be done; Followed by an analysis of the control flow control system, technical requirements are given through the analysis of the overall design program; Finally, the thesis of the program flow and friendly man-machine interface design for a comprehensive exposition can be seen on the screen display control process steps. Debugging by simulation show that the control system design is correct and effective.
 The success of this research can greatly increase productivity, save labor, to meet the needs of the market.
