【正文】 s design 1. power source return route 　　 The PLC power supply is generally AC85240V (also has DC24V), adapts the power source scope to be wide, but for the antijamming, should install the power source to purify the part (for example power source filter, 1:1 insulating transformer and so on) on DC24V power source39。s steady operation is very important. 3. The storage capacity and the instruction carry out the speed are the PLC shaping important targets, generally the reserves is bigger, the speed quicker PLC price to be higher, although overseas various factories product more or less the same, but also has certain difference. “COM choice, different PLC product, it COM a quantity is dissimilar, some COM belt 8 output spots, some belt 4 output spots, also has the belt 1 or 2 output spot. When the load type are many, and the electric current is big time, uses one COM a belt 12 output product, when the load type minority quantity are many, uses one COM a belt 48 output product. 5. Because each Manufacturer39。s selecting and purchasing: in the present market39。s CPU instructions with stepbystep process to store the address of the program counter, running in the process, each step in the implementation of the automatic counter plus 1, stepbystep process from the start (zerostep number), followed by the final step to the implementation of the (usually END mand), and then return to start stepbystep cycle of operation. Each PLC pleted a cycle of the time required for the operation known as a scanning cycle. Different models of the PLC, scanning cycle to cycle in a microsecond between the scores of microseconds. PLC ladder program used in calculating logic, to show the advantages of quick, microsecond in the order of magnitude, calculating logic 1K procedures less than 1 ms. It all have input as a switch to handle the volume, 16bit (also 32bit) for a simulated traffic. PLC largescale use of a CPU to plete the simulation of the amount of puting. The results sent to the PLC same I / O points system, with PLC than DCS, the cost should be lower (about 40% of the province to around). PLC special operation did not stop it with software and hardware are mon, so maintenance costs much lower than the DCS. One of the PLC controller, you can receive thousands of I / O points (up to more than 8000 I / O). If the object is a chain of equipment, small loop, the PLC to adopt more appropriate. As a result of General PLC control software in the design of management information systems, to be easier. Over the past 10 years, with the PLC to lower prices and growing user demand, a growing number of small and mediumsized equipment to start using PLC control, PLC in China grew rapidly. With China39。參考文獻(xiàn)[1] 王鶯. 工業(yè)可編程控制器的現(xiàn)狀與發(fā)展趨勢(shì)[J]. 北京: 航天技術(shù)與民品, 1999[2] 潘元明. 國(guó)內(nèi)外全自動(dòng)洗衣機(jī)現(xiàn)狀[J]. 家電大視野, 2003[3] 吳中俊主編. 可編程控制器原理及應(yīng)用[M]. 北京: 機(jī)械工業(yè)出版社, 2004[4] 吳存宏. 淺談PLC在全自動(dòng)洗衣機(jī)中運(yùn)用[J]. 家用電器科技,2000[5] 蔣金周. 全自動(dòng)洗衣機(jī)的PLC智能控制[J]. 北京: 機(jī)電一體化, 2004[6] 王永華. 電氣控制及PLC應(yīng)用技術(shù)[M]. 北京: 北京航空航天大學(xué)出版社, 2003[7] 殷洪義. 可編程控制器選擇設(shè)計(jì)與維護(hù)[M]. 北京: 機(jī)械工業(yè)出版社, 2002 [8] 羅宇航. 流行PLC實(shí)用程序及設(shè)計(jì)[M]. 西安電子科技大學(xué)出版社, 2006[9] 許謬. 電氣控制與PLC控制技術(shù)[M]. 北京: 機(jī)械工業(yè)出版社, 2005[10] 許謬, 王淑英. 電氣控制與PLC控制技術(shù)[M]. 北京: 機(jī)械工業(yè)出版社, 2005[11] 袁亮.

Meanwhile, the relay control systerm has already been few used on the machine control systerm is inferior in ability of antiinterference, high in requirement of working environment and long in desigong and developing cycle of the control systerm. So its application has being on deining trnd in the automation conrol field by year.The electrical control system of z3040 Radial arm drill has many defects such as plex circuit, high failure rate, large maintenance workload, poor reliability and flexibility. This paper introduces the z3040 Radial arm drill relay contact analog control system reformation with PLC to guarantee the rapidity, accuracy and rationality of electric control system. It satisfied real production demand and enhance the economic benefit.The original was introduced initial controller of programmable distinguishing feature and performance. Analyses on z3040’s Radial arm drill technique property and the work cycle distance travelled by a stream of water base, expounded the initial controller of application ES’s set programmable carrying on the technological transformation system design to such, and finish e out the control procedure trapezium picture.What is a PLC control system? Since the 1960s the United States to launch programmable logic controller (Programmable Logic Controller, PLC) to replace conventional control devices since the relay, PLC has been rapid development in various parts of the world have been widely used. At the same time, PLC39。在此特別感謝我們組的指導(dǎo)老師韓英韓老師段春霞段老師，她們?cè)谖覀冏霎厴I(yè)論文期間做出了很大的努力，爭(zhēng)取讓組里的每一位同學(xué)精益求精的完成論文，提高答辯質(zhì)量，這是論文可以順利完成的最重要的原因。所以，在接下來(lái)的路上還需要更多的人做出更多的努力，雖然這個(gè)設(shè)計(jì)只是一個(gè)自動(dòng)焊錫機(jī)，但他更是一種努力的方向。自動(dòng)焊錫機(jī)的設(shè)計(jì)有很多的方式，利用PLC只是其中一種，因?yàn)镻LC操作簡(jiǎn)單，控制能力較強(qiáng)，所以在這里我們是基于PLC的設(shè)計(jì)。對(duì)于本設(shè)計(jì)，首先打開啟動(dòng)按鈕開關(guān)SB1，除渣機(jī)械手上升/下降電機(jī)得電上升，按下SQ7（假設(shè)除渣機(jī)械手到達(dá)上升限位開關(guān)，后文出現(xiàn)的開關(guān)SQ全部為限位開關(guān)），除渣機(jī)械手運(yùn)行改變?yōu)橄蜃?，按下SQ5，除渣機(jī)械手運(yùn)行改變?yōu)橄蛳拢聪耂Q8，除渣機(jī)械手運(yùn)行改變?yōu)橄蛴?，按下SQ6，除渣機(jī)械手運(yùn)行改變?yōu)橥Ｖ?，此時(shí)左側(cè)的焊盤得電上升，
