1、YNL prefabrication trigger electric control system design PLC is one kind specially for the digital operation operation electronic installation which applies under the industry environment designs. It uses may the coding memory, uses for in its internal memory operation and so on actuating logic op

2、eration, sequence operation, time, counting and arithmetic operation instructions, and can through digital or the simulation-like input and the output, controls each type the machinery or the production process. PLC and the related auxiliary equipment should according to form a whole easy with the i

3、ndustrial control system, easy to expand its function the principle to design.” In the 1970s the last stage, the programmable controller entered the practical application development phase, the computer technology has introduced in comprehensively the programmable controller, causes its function to

4、 have the leap. The higher operating speed, the subminiature volume, the more reliable industry antijamming design, the simulation quantity operation, the PID function and the extremely high performance-to-price ratio has established it in the modern industry status. In the early-1980s, the programm

5、able controller has obtained the widespread application in the advanced industrial nation. This time programmable controller develops the characteristic is large-scale, the high velocity, the high performance, the product seriation. This stages another characteristic is in the world produces the pro

6、grammable controllers country to increase day by day, the output rises day by day. This symbolizes that the programmable controller marched into the mature stage. The 20th century last stage, the programmable controllers development characteristic was even more adapts in the modern industry need.

7、From the control scale, this time has developed the large-scale machinery and subminiature machine; From the control, was born various special function unit, used in the pressure, the temperature, the rotational speed, the displacement and so on all kinds of control situation; From product necessary

8、 ability, has produced each kind of man-machine contact surface unit, the correspondence unit, caused to apply the programmable controllers industrial control equipment necessary to be easier. At present, the programmable controller in domain and so on machine manufacture, petroleum chemical industr

9、y, metallurgy steel and iron, automobile, light industry applications obtained the considerable development. Our country programmable controllers introduction, applies, the development, the production to follow the reform and open policy to start. At first has used the programmable controller ma

10、ssively in the introduction equipment. Then expanded the PLC application unceasingly in each kind of enterprises production equipment and the product. At present, our country have been possible to produce the middle and small scale programmable controller. East Shanghai the room electricity Limited

11、company produces the CF series, Hangzhou engine bed electrical equipment factory productions DKK and D series, Dalian Aggregate machine-tool Research institute produces S series, the Suzhou Electronic accounting machine Factory productions YZ series and so on many kinds of products have had certain

12、scale and have obtained the application in the manufactured products. In addition, the non-flowers of tin light company, Chinese-foreign joint ventures and so on Shanghai Township Island Company are also our country quite famous PLC Manufacturers. May anticipate that along with our country moderniza

13、tion processs thorough, PLC will have the broader application world in our country. Uses the manual operation in view of the YNL draw die machine electric control system, the existence operation is complex, the operation requests high, needs specially shortcomings and so on operators, has designed

14、PLC the control system. Has given the electrical machinery main return route, the PLC periphery wiring diagram; Has established the systems operation trapezoidal chart and the instruction list; And to this system key element shaping. After the improvement control system has realized the entire syste

15、m board process automation, not only raised the production efficiency, but also has saved the labor force, reduced the production cost, may obtain a greater economic efficiency. YNL型預(yù)制板機(jī)電氣控制系統(tǒng)設(shè)計(jì) PLC是一種專門為在工業(yè)環(huán)境下應(yīng)用而設(shè)計(jì)的數(shù)字運(yùn)算操作的電子裝置。它采用可以編制程序的存儲(chǔ)器，用來在其內(nèi)部存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序運(yùn)算、計(jì)時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算

16、等操作的指令，并能通過數(shù)字式或模擬式的輸入和輸出，控制各種類型的機(jī)械或生產(chǎn)過程。PLC及其有關(guān)的外圍設(shè)備都應(yīng)該按易于與工業(yè)控制系統(tǒng)形成一個(gè)整體，易于擴(kuò)展其功能的原則而設(shè)計(jì)?！? 20世紀(jì)70年代中末期，可編程控制器進(jìn)入實(shí)用化發(fā)展階段，計(jì)算機(jī)技術(shù)已全面引入可編程控制器中，使其功能發(fā)生了飛躍。更高的運(yùn)算速度、超小型體積、更可靠的工業(yè)抗干擾設(shè)計(jì)、模擬量運(yùn)算、PID功能及極高的性價(jià)比奠定了它在現(xiàn)代工業(yè)中的地位。20世紀(jì)80年代初，可編程控制器在先進(jìn)工業(yè)國家中已獲得廣泛應(yīng)用。這個(gè)時(shí)期可編程控制器發(fā)展的特點(diǎn)是大規(guī)模、高速度、高性能、產(chǎn)品系列化。這個(gè)階段的另一個(gè)特點(diǎn)是世界上生產(chǎn)可編程控制器的國家日益增多，產(chǎn)

17、量日益上升。這標(biāo)志著可編程控制器已步入成熟階段。 20世紀(jì)末期，可編程控制器的發(fā)展特點(diǎn)是更加適應(yīng)于現(xiàn)代工業(yè)的需要。從控制規(guī)模上來說，這個(gè)時(shí)期發(fā)展了大型機(jī)和超小型機(jī)；從控制能力上來說，誕生了各種各樣的特殊功能單元，用于壓力、溫度、轉(zhuǎn)速、位移等各式各樣的控制場合；從產(chǎn)品的配套能力來說，生產(chǎn)了各種人機(jī)界面單元、通信單元，使應(yīng)用可編程控制器的工業(yè)控制設(shè)備的配套更加容易。目前，可編程控制器在機(jī)械制造、石油化工、冶金鋼鐵、汽車、輕工業(yè)等領(lǐng)域的應(yīng)用都得到了長足的發(fā)展。 我國可編程控制器的引進(jìn)、應(yīng)用、研制、生產(chǎn)是伴隨著改革開放開始的。最初是在引進(jìn)設(shè)備中大量使用了可編程控制器。接下來在各種企業(yè)的生產(chǎn)設(shè)備及產(chǎn)

18、品中不斷擴(kuò)大了PLC的應(yīng)用。目前，我國自己已可以生產(chǎn)中小型可編程控制器。上海東屋電氣有限公司生產(chǎn)的CF系列、杭州機(jī)床電器廠生產(chǎn)的DKK及D系列、大連組合機(jī)床研究所生產(chǎn)的S系列、蘇州電子計(jì)算機(jī)廠生產(chǎn)的YZ系列等多種產(chǎn)品已具備了一定的規(guī)模并在工業(yè)產(chǎn)品中獲得了應(yīng)用。此外，無錫華光公司、上海鄉(xiāng)島公司等中外合資企業(yè)也是我國比較著名的PLC生產(chǎn)廠家。可以預(yù)期，隨著我國現(xiàn)代化進(jìn)程的深入，PLC在我國將有更廣闊的應(yīng)用天地。 針對YNL拉模機(jī)電氣控制系統(tǒng)采用手動(dòng)操作，存在操作復(fù)雜，操作要求高，需要專門操作人員等缺點(diǎn)，設(shè)計(jì)了PLC控制系統(tǒng)。給出了電機(jī)主回路、PLC外圍接線圖；編制了系統(tǒng)運(yùn)行梯形圖和指令表；并對本系統(tǒng)所主要元件選型。改進(jìn)后的控制系統(tǒng)實(shí)現(xiàn)了整個(gè)制板過程的自動(dòng)化，不但提高了生產(chǎn)效率，還節(jié)省了勞動(dòng)力，降低了生產(chǎn)成本，可以取得更大的經(jīng)濟(jì)效益。
