1、毕业设计（论文）外文翻译PLC technique discussion and future development学生姓名 XXX班 级 XX机电XX 学号XXXX学院名称机电工程学院专业名称机械设计制造及其自动化指导教师XXX2014年 5月 22日英文文献PLC technique discussion and future developmentAlong with the development of the ages, the technique that is nowadays is also gradually perfect, the conetition plays mo

2、re and more strong; the operation that list depends the artificial has already cant satisfied with the current manufecturing industry foreground, also carit guarantee the request of the higher quantity and high new the image of the technique business enterprise.The people see in produce practice, au

3、tomate brought the tremendous convenience and the product quantities for people 叩 of assurance, also eased the personnels labor strength, reduce the establishment on the personnel. The target control of the hard realization in many complicated production lines, whole and excellent turn, the best dec

4、ision etc., well-trained 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 cakulator exactly to carry out, imitate these intelligences behavior; moderating th

5、e work through persons brain and calculators, with the mode that persoris machine combine, for resolve the very complicated problem to look for the best pathWe come in sight of the control that links after the electric appliances in various situation, that is already the that time generation past, n

6、ow of after use in the mold a perhaps sinple equipments of grass-roots control that the electric appliances can do for the low level only; And the PLC emergence also became the epoch-making topic, adding the vivid software control through a very and stable hardware, making the automation head for th

7、e new high tide.The PLC biggest characteristics lie in: The electrical engineering teacher already no longer electric hardware 叩 too many calculations of cost, as long as order the importation that the button switch or the importation of the sensors order to link the PLC 中 can solve problem, pass to

8、 output to order the conjunction contact machine or control the start equipments of the big power after the electric appliances, but the e冲ortation equq)ments direct conjunction of the small power canPLC internal containment have the CPU of the CPU, and take to have an 1/ O for expand of exterior to

9、 connect a peoples 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 fogic operation ability and can read the procedure save the contents of the machine to drive the homologous saving machi

10、ne and 1/ Os to connect after pass the calculation; The 1/ Oadd inner part is tired the input and output system of the machine and exterior link, and deposit the related data into the procedure saving machine or data saving machine; The saving machine can deposit the data that the 1/ O input in the

11、saving machine, and in work adjusting to become tired to add the machine and 1/ Os to connect, saving machine separately saving machine RAM of the procedure saving machine ROM and datas, the ROM can do deposit of the data permanence in the saving machine, but RAM only for the CPU confutes the tenpor

12、ary calculation usage of hour ofbufifer 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 become the topic that we feil, but stay to our is a concern to come to internal resources o

13、f 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

14、the electric appliances to control, make the electrical engineering teacher while weaving to write the procedure very easy comprehended 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

15、also one part that the people conprehend more and easily, in a lot of equments, 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; But lead even is

16、a fetal error greatly is what we carit is tolerant of New technique always for bringing more safe and convenient operation for us, make we a lot of problems for fece 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 e冲lains it into the touch to hold or man-machine interface you knew it combines with the PLC to our larger space.
