自動售貨機模擬操作面板 圖 52 自動售貨機模擬操作面板 本設計統(tǒng)一采用按鈕開關模擬物品選擇,按鈕內有綠燈和紅燈分別表示可購買物品和物品銷售完;指示燈模擬物品輸出及找零如圖 52 所示。一個平??此坪唵问褂梅奖愕淖詣邮圬洐C,其實并不是那么容易就做成的。 在接到題目后,起初感覺無從下手,在思考過一段時間后,我們通過網絡以及去圖書館查閱資料,獲得了一些有關自動售貨機以及 PLC 編程方面的信息。經過多次修改以及調試,我們最終獲得成功,實現了預期的功能。 經過 兩個禮拜 的學習、研究以及經過 孫 老師的指導 .終于按時完成了 課程 設計 。 自動售貨機是由于勞動密集型的產業(yè)構造 向技術密集型社會轉變的產物。所以說 ,自動售貨機是今后小商品和飲料銷售方式的一個很好的發(fā)展趨勢 。 通過本次課程設計,我的收獲很大,對 PLC 的編程有了更進一步的掌握,增加了我的實踐動手能力。 致謝 這次課程設計之所以取得成功,得到了多方面的幫助。再次,感謝指導老師的幫助,在設計過程中遇到難題時,指導老師總是耐心的提供幫助,在這里向老師表示由衷地感謝。可編程序控制器原理與應用 現代電氣控制及 PLC 應用技術 .

The target control of the hard realization in many plicated production lines, whole and excellent turn, the best decision etc., welltrained operation work, technical personnel or expert, governor but can judge and operate easily, can acquire the satisfied result. The research target of the artificial intelligence makes use of the calculator exactly to carry out, imitate these intelligences behavior, moderating the work through person39。s machine bine, for resolve the very plicated problem to look for the best path We e in sight of the control that links after the electric appliances in various situation, that is already the that time generation past, now of after use in the mold a perhaps simple equipments of grassroots control that the electric appliances can do for the low level only。s address and saving machine three big pieces to constitute, CPU core is from an or many is tired to add the machine to constitute, mathematics that they have the logic operation ability, and can read the procedure save the contents of the machine to drive the homologous saving machine and I/ Os to connect after pass the calculation。 The saving machine can deposit the data that the I/ O input in the saving machine, and in work adjusting to bee tired to add the machine and I/ Os to connect, saving machine separately saving machine RAM of the procedure saving machine ROM and dates, the ROM can do deposit of the data permanence in the saving machine, but RAM only for the CPU putes the temporary calculation usage of hour of buffer space. The PLC anti interference is very and excellent, our root need not concern its service life and the work situation bad, these all problems have already no longer bee the topic that we fail, but stay to our is a concern to e to internal resources of make use of the PLC to strengthen the control ability of the equipments for us, make our equipments more gentle. PLC language is not we imagine of edit collected materials the language or language of Cs to carry on weaving the distance, but the trapezoid diagram that the adoption is original after the electric appliances to control, make the electrical engineering teacher while weaving to write the procedure very easy prehended the PLC language, and a lot of non electricity professional also very quickly know and go deep into to the PLC. Is PLC one of the advantage above and only, this is also one part that the people prehend more and easily, in a lot of equipments, the people have already no longer hoped to see too many control buttons, they damage not only and easily and produce the artificial error easiest, small is not a main error perhaps you can still accept。t is tolerant of. New technique always for bringing more safe and convenient operation for us, make we a lot of problems for face on sweep but light, do you understand the HMI? Says the HMI here you basically not clear what it is, also have no interest understanding, change one inside text explains it into the touch to hold or manmachine interface you knew, and it bines with the PLC to our larger space. HMI the control not only is reduced the control press button, increase the vivid of the control, more main of it is can sequence of, and at can the change data input to output the feedback with data, control in the temperature curve of imitate but also can keep the manifestation of view to e out. And can write the function help procedure through a plait to provide the help of various what lies in one39。 to be good very. At a lot of situations, the list is a smooth movement that can39。 But take data in the watch for an instruction procedure that controls the PLC, that had the difficulty very much, for example you have to control one pedestal robot to press the action work that you imagine, you will draw up for it the form that a procedure bine with the data sends out to pass by. The form that information transport contain single work, the half a work and the difference of a workers .The meaning of the single work also is to say both, a can send out only, but a can receive only, for example a spy he can receive the designation of the superior only, but can39。 A work of half is also 2 and can send out similar to accept the data, but can39。t answer the phone, the other party also。t do other works. When you are reading the book, you hear someone knock on door, you stop to start up of affair, open the door and bine to continue with the one who knock on door a dialogue, the telephone of this time rang, you signal hint to connect a telephone, after connecting the telephone through, return overdo e together knock on door to have a conversation, after dialogue plete, you continue again to see your book, this kind of circumstance we are called the interruption to it, it has the authority, also having sex of have the initi
