【正文】 t have an error margins in a data deliver, otherwise the whole piece according to pare the occurrence mistake, this on the hardware is a bigger difficulty. Applied more and more extensive in some appropriative equipments, be like the appropriative medical treatment equipments, the numerical signal equipments...etc., in pare the one data deliver, its result is very good.And the different step is an application the most extensive, this receive benefit in it of technique difficulty is opposite and want to be small, at the same time not need to prepare the specialized clock signal, its characteristics to lie in, its data is partition, the longlost send out and accept, be the CPU is too busy of time can grind to a stop sex to work, also reduced the difficulty on the hardware, the data throw to lose at the same time opposite want to b。t answer the phone, the other party also。 A work of half is also 2 and can send out similar to accept the data, but 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 work .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。 to be good very.At a lot of situations, the list is a smooth movement that can39。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, 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。 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 data , 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。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。s machine bine, for resolve the very plicated problem to look for the best pathWe 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 labor strength, reduce the establishment on the personnel. 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。t satisfied with the current manufacturing industry foreground, also can39。參考文獻(xiàn)[1]馮嘉花. 變頻調(diào)速改造鍋爐房55 kW循環(huán)水泵［J］.電氣時(shí)代，2007，26(5)：94～95[2][M].北京：機(jī)械工業(yè)出版社1998，8[3][M].北京：機(jī)械工業(yè)出版社，200l，6[4][J].微機(jī)算機(jī)信息，2005，（7）：21～23[5]趙明,[M].北京：機(jī)械工業(yè)出版社,2004，5[6][J].電氣應(yīng)用， 2022[7]裘旭東，［J］.煤礦機(jī)械，2007，28(12)：150～152[8]李 明，[J].清華大學(xué)學(xué)報(bào)，1999，(39)3，8891[9]王永平，—200PLC的高性能電熱鍋爐控制系統(tǒng)[J].儀表技術(shù)與傳感器，2002，(3)2628[10]吳春旺，陳 [J].電工技術(shù)，2006，3，7172[11]楊　智,明麗萍,[J].鍋爐制造，2001，7[12]宋書中，葛 [J].電氣自動(dòng)驗(yàn)化，2000，6，3436[13]、課程設(shè)計(jì)指導(dǎo)書[M].北京：高等教育出版社，2001，7[14][M].北京：機(jī)械工業(yè)出版社，2003，6[15]，電氣控制與PLC應(yīng)用[M].北京：電子工業(yè)出版社，2006，2[16][M].西安：西安電子科技大學(xué)出版社，2006，1[17][M]．重慶：重慶大學(xué)出版社，2004，8[18][M]．哈爾濱：哈爾濱工業(yè)大學(xué)出版社．1999，1[19][M]．北京:電子工業(yè)出版社,2004，6[20][M]．北京：江西科學(xué)技術(shù)出版社，2002，2
