制造業(yè)作為立國(guó)之本，強(qiáng)國(guó)之基，是國(guó)民經(jīng)濟(jì)的基礎(chǔ)產(chǎn)業(yè)。經(jīng)過幾十年的發(fā)展，我國(guó)制造業(yè)取得了舉
世矚目的發(fā)展成就，制造在國(guó)內(nèi)需求的同時(shí)，也走向了市場(chǎng)。
2017年《財(cái)富》“500強(qiáng)”排行榜中，企業(yè)已經(jīng)達(dá)到115家，企業(yè)入榜數(shù)量連續(xù)第十
四年增長(zhǎng)。但制造類企業(yè)尤其是創(chuàng)新型企業(yè)比較少。總體看，我國(guó)制造業(yè)仍處在分工的中低端，
大而不強(qiáng)。
隨著新經(jīng)濟(jì)時(shí)代的來臨，“制造2025”戰(zhàn)略的實(shí)施，我國(guó)正在由制造大國(guó)向制造強(qiáng)國(guó)轉(zhuǎn)變，推動(dòng)
制造業(yè)智造升級(jí)、加快邁向中的任務(wù)十分緊迫。
當(dāng)前我國(guó)制造業(yè)加快智造升級(jí)，在穩(wěn)增長(zhǎng)、調(diào)結(jié)構(gòu)、促轉(zhuǎn)型的征途上，不斷迸發(fā)出新動(dòng)力，與此同時(shí)
各項(xiàng)與制造業(yè)相關(guān)政策的為制造業(yè)的發(fā)展和轉(zhuǎn)型升級(jí)提供了強(qiáng)的政策支持。

1. 制定設(shè)備運(yùn)行方案
制定方案就是根據(jù)生產(chǎn)工藝的要求，分析各輸入、輸出與各種操作之間的邏輯關(guān)系，確定需要檢測(cè)的量和控制的方法，并設(shè)計(jì)出系統(tǒng)中各設(shè)備的操作內(nèi)容和操作順序。據(jù)此便可畫出流程圖。
2. 畫控制流程圖
對(duì)于較復(fù)雜的應(yīng)用系統(tǒng)，需要繪制系統(tǒng)控制流程圖，用以清楚地表明動(dòng)作的順序和條件。對(duì)于簡(jiǎn)單的控制系統(tǒng)，可省去這一步。
3. 制定系統(tǒng)的抗干擾措施
根據(jù)現(xiàn)場(chǎng)工作環(huán)境、干擾源的性質(zhì)等因素，綜合制定系統(tǒng)的硬件和軟件抗干擾措施，如硬件上的電源隔離、信號(hào)濾波，軟件上的平均值濾波等。
4. 編寫程序
根據(jù)被控對(duì)象的輸入輸出信號(hào)及所選定的PLC型號(hào)分配PLC的硬件資源，為梯形圖的各種繼電器或接點(diǎn)進(jìn)行編號(hào)，再按照軟件規(guī)格說明書(技術(shù)要求、編制依據(jù)、測(cè)試)，用梯形圖進(jìn)行編程。
5. 軟件測(cè)試
剛編寫好的程序難免有缺陷或錯(cuò)誤。為了及時(shí)發(fā)現(xiàn)和消除程序中的錯(cuò)誤和缺陷，需要對(duì)程序進(jìn)行離線測(cè)試。經(jīng)調(diào)試、排錯(cuò)、修改及模擬運(yùn)行后，才能正式投入運(yùn)行。
6. 編制程序使用說明書
當(dāng)一項(xiàng)軟件工程完成后，為了便于用戶和現(xiàn)場(chǎng)調(diào)試人員的使用，應(yīng)對(duì)所編制的程序進(jìn)行說明，說明書應(yīng)包括程序設(shè)計(jì)的依據(jù)、結(jié)構(gòu)、功能、流程圖，各項(xiàng)功能單元的分析，PLC的IO信號(hào)，軟件程序操作使用的步驟、注意事項(xiàng)等。

機(jī)械手控制系統(tǒng)設(shè)計(jì)
1. 工藝過程及控制要求
1) 工藝過程
圖6.1所示為一簡(jiǎn)易物料搬運(yùn)機(jī)械手的工藝流程圖。該機(jī)械手是一個(gè)水平垂直位移的機(jī)械設(shè)備，其操作是將工件從左工作臺(tái)搬運(yùn)到右工作臺(tái)，由光耦合器VLC來檢測(cè)工作臺(tái)上有沒有工件。機(jī)械手通常位于原點(diǎn)，它的動(dòng)作全部由氣缸驅(qū)動(dòng)，而氣缸則由相應(yīng)的電磁閥控制。其中，上升下降和左移右移分別由雙線圈二位電磁閥控制，放松夾緊由一個(gè)單線圈二位電磁閥(稱為夾緊電磁閥)控制。
2) 控制要求
機(jī)械手整個(gè)搬運(yùn)過程要求都能自動(dòng)控制。在啟動(dòng)過程中能切換到手動(dòng)控制及自動(dòng)控制或半自動(dòng)控制(又稱單周期控制)，以便對(duì)設(shè)備進(jìn)行調(diào)整和檢修。圖6.2是機(jī)械手控制系統(tǒng)的邏輯流程圖。系統(tǒng)啟動(dòng)之前，機(jī)械手處于原始位置，條件是機(jī)械手在高位﹑左位。
