【正文】 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)（論文） I 基于 PLC 的自動(dòng)送料裝車控制系統(tǒng)設(shè)計(jì) 摘 要 可編程序 邏輯 控制器（ Programmable logic controller）簡(jiǎn)稱 PLC，由于PLC 的 可靠性高、環(huán)境適應(yīng)性強(qiáng)、靈活通用、使用方便、維護(hù)簡(jiǎn)單 ， 所以PLC 的應(yīng)用領(lǐng)域在迅速擴(kuò)大 。 尤其是近幾年來(lái)， PLC 的成本下降，功能又不段增強(qiáng)，所以，目前 PLC 在國(guó)內(nèi)外已被廣泛應(yīng)用于各個(gè)行業(yè)。本設(shè)計(jì)是為了實(shí)現(xiàn)送料小車的手動(dòng)和自動(dòng)化的轉(zhuǎn)化，改變以往小車 的單純手動(dòng)送料，減少了勞動(dòng)力，提高了生產(chǎn)效率，實(shí)現(xiàn)了自動(dòng)化生產(chǎn)。 而且本送 料小車的設(shè)計(jì)是由于工作環(huán)境惡劣，不允許人進(jìn) 入工作環(huán)境的情況下 而產(chǎn)生 的。 首先，用 PLC 編程實(shí)現(xiàn)送料系統(tǒng)的基本功能。其次，畫(huà)出組態(tài)仿真畫(huà)面，定義組態(tài)變量，對(duì)組態(tài)中的一些基本量如（管道中物料的流動(dòng)）進(jìn)行仿真。然后，把 PLC 程序和組態(tài)結(jié)合，通過(guò)數(shù)據(jù)連接，實(shí)現(xiàn)通信。最后，運(yùn)行PLC 程序及組態(tài)仿真程序，實(shí)現(xiàn)組態(tài)對(duì)整個(gè)系統(tǒng)實(shí)時(shí)監(jiān)控。在實(shí)現(xiàn)組態(tài)控制時(shí)，本文詳細(xì)的介紹了組態(tài)王軟件的編程及通信，使讀者很容易的了解組態(tài)王軟件運(yùn)行仿真過(guò)程。 關(guān)鍵詞 ： PLC,組態(tài)王 ,監(jiān)控 ,仿真 洛陽(yáng)理工學(xué)院畢業(yè)設(shè)計(jì)（論文） II Design of automatic loading control system based on PLC ABSTRACT Programmable logic controller referred to PLC ， because of the high reliability PLC adaptability， flexibility， environment， use convenient， simple maintenance， so the application of PLC in the rapidly expanding. Especially in recent years， the cost of PLC down and function increasing， so， at the moment ， PLC at home and abroad ， has been widely used in various order to achieve the design of the car feed the transformation of manual and automated， simple to change the past， car manual feed， a reduction of the workforce， increased productivity， automated production! Feeding and the car is designed to be as a result of bad working conditions are not allowed to enter the working environment of the circumstances formed. First, programs with PLC realizes feed system39。s basic function. Next, draws the configuration simulation picture, the definition configuration variable, like (in pipeline material flowing) carries on the simulation to configuration some fundamental quantities. Then, the PLC procedure and the configuration union, through the data connection, realizes the correspondence. Finally, moves the PLC procedure and the configuration simulated program, realizes the configuration realtime monitoring overall system. When realizes the configuration control, this article detailed introduction configuration king software39。s programming and the correspondence, caused the reader very easy to understand the configuration king software movement simulation process.
