1、外文翻译资料Air operated moves the carrier vehicle and the PLC controlAir operated namely uses the air pump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.The programmable controller (PLC) is taken the microp
2、rocessor as the core, collection computer technology, the automated control technology in a body one new industry control system. PLC has used the model computer structure, mainly includes CPU, RAM, ROM and the input/ Output connection electric circuit and so on. If regards as PLC a system, this sys
3、tem is composed by the input variable -PLC- output variable, the exterior each kind of switching signal, the simulated signal, the sensor examine the signal took PLC the input variable, they input after the PLC exterior post to the internal register in, after the PLC interior logic operation or othe
4、r each kind of operation, processing delivers the output terminal, they are the PLC output variable, carries on each kind of control by these output variables to the auxiliary equipment.The PLC control system adopts generally easy to understand and to grasp trapezoidal chart language and face indust
5、ry control simple instruction. The image is direct-viewing, is based on the field bus technology, opens completely, and uses the advanced software and hardware technology. The PLC control has the structure simply nimble, the anti-jamming ability strong, safe reliable, installs the convenience, the f
6、ailure rate lowly, the maintenance is simple, large scale saves the use cost the characteristic, can satisfy each kind of center small scale process control, the smooth logic control and the data acquisition duty demand, widely has used in gradually in the industry control system, including domain a
7、nd so on metallurgy, mining industry, machinery, light industry, has provided the powerful tool for the industrial automation.The control engineering in the near future to will use in the logical equipment which programmed the process and the machinery controls carrying on an investigation, although
8、 the computer and computer technology already provided the infinite control for each kind of control to be possible, but PLC still was a important part. In this investigation, it will surpass half number of people to expand its PLC in the future 12 months the investment. It will surpass 40% person i
9、n the future investment many in the past 12 months. The PLC application scope is extremely widespread. In this 300 individual participation investigation, majority of PLC all uses in the machinery control, the process control follows closely after that, then is the movement control, the batch contro
10、l and the diagnosis. The majority uses in directly the factory level (54%), uses in OEM is 25%, two all is 17%. In the industrial production assembly line, must move frequently the transmission belt A on goods to conveyer belt B on. If direct artificially is engaged in this kind of duplicated work,
11、arid, tasteless also labor intensity big, is easy to cause operates workers weariness, appears the mistake. But uses the air operated manipulator carries on the transporting according to the stipulation movement and the rule, may achieve fast, accurate, is convenient, big reduces the labor intensity
12、, enhances the production the automat city. Air operated manipulator this kind of orderly movement, uses PLC to carry on the control, and may facilitate realization.The robot sets an example the integration of machinery intelligence equipment. flows in the automated system in the manufacture and the
13、 thing to act the strong character. But the standard industry robot only is has certain degrees of freedom an intelligent electromechanical device. Isolation robot in the actual operating mode is not any application value. only then according to factor and so on work content, work piece form, qualit
14、y, contour characteristic and size matches to the robot by the auxiliary machinery installment like hand fingernail which adapts, it only then can become the practical production equipment. air operated not only is 1.th robot main drive type is quick-moving requesting machinist terminal execution qu
15、ick-moving, the structure simple, the control maintenance convenient, the cost to be low, Moreover the flexible transformation quick. and has the versatile assembly and the transporting and so on ascends when puts, the transmission movement work, uses air operated, or air operated combines with othe
16、r transmission control technologies further increases its movement precision and the flexibility relatively fixed. Moreover the movement is frequent, the duplicated strong center low power operating mode in the work space scope limited, working routine, and uses the air operated modular organization unit the combination to realize the machinist work, can manifest the air operated technical effective substitution manpower operation realization production process Taiwan
