基于PLC的切割機(jī)控制系統(tǒng)設(shè)計

　　摘  要：

　　隨著自動行業(yè)的發(fā)展，在生活生產(chǎn)中到處都出現(xiàn)了不同種類的自動化設(shè)備。在當(dāng)今的工業(yè)領(lǐng)域中，胚體的切割是加工過程中最為重要的步驟，也是保證成品質(zhì)量的重要工序。

　　本文在基于PLC的切割機(jī)控制系統(tǒng)設(shè)計中，設(shè)計了PLC控制系統(tǒng)總體方案，給出了軟、硬件設(shè)計與實現(xiàn)方案。在硬件設(shè)計部分，闡述了電動機(jī)主電路及其電器控制電路的設(shè)計過程，給出了這兩個電路的電器元件的選擇結(jié)果。在控制電路的設(shè)計部分，闡述了I/O接線圖的設(shè)計過程，給出PLC及其輸入／輸出元件的選擇結(jié)果。在軟件設(shè)計部份詳細(xì)地闡述了PLC用戶程序的設(shè)計過程，其中包括對公用程序、手動程序、自動程序與故障報警程序的設(shè)計過程的闡述，并給出了上述所有程序的梯形圖和指令表。

　　關(guān)鍵詞：切割機(jī)；PLC；控制系統(tǒng)。

Abstract: 

　　With the development of automatic industry,various kinds of automatic equipments appear all around of our life and production.In today's industrial field,Incising the material of tube and plank stuff is not only the most important step during the procedure of processing finished products but the important process of ensuring the products'quality.

　Designed the PLC control system a total project in according to the PLC static cutting the machine control system design, give soft, hardware design and carry out a project. Design part in the hardware, elaborate the design process of the electric motor main electric circuit and its electric appliances control electric circuit, gave the choice of these two electric appliances components of electric circuits the result. Be controlling the design part of the electric circuit, elaborate I/O to connect the design process of the line diagram, give the PLC and the choice of its input/output component the result. Design the design process that the part elaborated the PLC customer procedure in detail in the software, include among them to the public procedure, hand to move the design process that the procedure, automatic procedure and give alarm signal procedure to elaborate, and gave above-mentioned all trapezoid diagrams of procedures and the repertoire.

Keywords:cutter; PLC; control system
