PLC technique discussion and future developmentT。J。byersElectronic Test Equipment—principles and ApplicationsPrinceton University .AmericaAlong with the development of the ages ， the technique that is nowadays is also gradually perfect, the competition plays more strong; the operation that list depends the artificial has already can't satisfied with the current manufacturing industry foreground， also can’t guarantee the request of the higher quantity and high new the image of the technique business enterprise.The people see in produce practice, automate brought the tremendous convenience and the product quantities for people up of assurance, also eased the personnel's 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 decision 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 calculator exactly to carry out ， imitate these intelligences behavior ， moderating the work through person's brain and calculators, with the mode that person’s machine combine, for resolve the very complicated problem to look for the best path.We come 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 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 har...
