plc控制系統(tǒng)設(shè)計(jì)－鍋爐輸煤系統(tǒng)

1、 畢業(yè)設(shè)計(jì)（論文）任務(wù)書 畢業(yè)設(shè)計(jì)（論文）任務(wù)書課題名稱： 課題名稱：PLC PLC控制系統(tǒng)設(shè)計(jì)－鍋爐輸煤系統(tǒng) 控制系統(tǒng)設(shè)計(jì)－鍋爐輸煤系統(tǒng) PLC 控制系統(tǒng)設(shè)計(jì)——鍋爐輸煤系統(tǒng)的方法。首先，介紹了 PLC 的一些基本常識(shí)問題。在具體的設(shè)計(jì)中，先講述了 PLC 設(shè)計(jì)的一些基本方法及步驟。詳細(xì)介紹了西門子公司的型號(hào)為 S7-200 的 PLC 的一些基本知識(shí)。之后重點(diǎn)講述了 PLC 程序設(shè)計(jì)中的啟動(dòng)，停止，位置選擇及輸出報(bào)警等問題，也講了

2、 I/O 點(diǎn)分配的一些事項(xiàng)并對(duì)本設(shè)計(jì)中的對(duì)象進(jìn)行了地址分配。在上位機(jī)的設(shè)計(jì)中，我用了工業(yè)組態(tài)軟件——組態(tài)王來進(jìn)行操作界面制作，并使之與 PLC 進(jìn)行通訊，使之達(dá)到遠(yuǎn)程控制的功能，中間又重點(diǎn)講述了制作操作界面的步驟及方法。關(guān)鍵詞: 輸煤系統(tǒng),PLC,I/O,組態(tài)王Design of PLC Control SystemThe System of Transport Coal in BoilerAbstractThis paper de
