【正文】 英文原文二 ： Air operated moves the carrier vehicle and the PLC control The PLC control system adopts generally easy to understand and to grasptrapezoidal chart language and face industry control simple instruction. The image isdirectviewing is based on the field bus technology opens pletely and uses theadvanced software and hardware technology. The PLC control has the structuresimply nimble the antijamming ability strong safe reliable installs the conveniencethe failure rate lowly the maintenance is simple large scale saves the use cost thecharacteristic can satisfy each kind of center small scale process control the smoothlogic control and the data acquisition duty demand widely has used in gradually inthe industry control system including domain and so on metallurgy mining industrymachinery light industry has provided the powerful tool for the industrialautomation. The control engineering in the near future to will use in the logical equipmentwhich programmed the process and the machinery controls carrying on aninvestigation although the puter and puter technology already provided theinfinite control for each kind of control to be possible but PLC still was a importantpart. In this investigation it will surpass half number of people to expand its PLC inthe future 12 months the investment. It will surpass 40 person in the futureinvestment many in the past 12 months. The PLC application scope is extremelywidespread. In this 300 individual participation investigation majority of PLC alluses in the machinery control the process control follows closely after that then is themovement control the batch control and the diagnosis. The majority uses in directlythe factory level 54 uses in OEM is 25 two all is 17. In the industrial production assembly line must move frequently thetransmission belt A on goods to conveyer belt B on. If direct artificially is engaged inthis kind of duplicated work arid tasteless also labor intensity big is easy to causeoperates workers weariness appears the mistake. But uses the air operatedmanipulator carries on the transporting according to the stipulation movement and therule may achieve fast accurate is convenient big reduces the labor intensityenhances the production the automat city. Air operated manipulator this kind oforderly movement uses PLC to carry on the control and may facilitate realization. The air operated hand fingernail is the present machinist transports the assemblyclass machinist in particular in captures in the technology to apply most universal to be possible to realize bidirectional captures voluntarily to the center moreoverthe redundant precision high. Capture the strength to be constant. and mayconveniently match meets each kind of jig. The air operated hand fingernail is directconnection between the machinist and of the work object the careful analysischooses the good air operated hand fingernail to relate directly to machinistsoperating performance. In the actual movement the hand fingernail supports on bothsides the strength to be supposed to guarantee is bigger than all static and the dynamicstrength sum total. The PLC procedure movement way is circulates the scanning waybut the non order carries out the way therefore any manipulator satisfies after itscondition namely starts the movement. Between various is parallel. The machinist isthe multidegrees of freedom open the type series structure. But changes the systemrequest speed high control area broad precision unceasingly in spatial and the timedynamics parameter along with its configuration high the traditional single degree offreedom anization control technology is far cannot satisfy this kind of controlledmember to be good because of the air operated machinist cancels much to themultistage localization control the pursue target point pointing accuracy and multiplespindle at the same time cooperates weakly to have the foreword movement controlbut little requests the high path precision thus simplified to the control systemrequest. The material mode of transport has the multipurpose function which may graspmay attract The pneumatic system electromagism cross valve selects the affluxboard collection attire method reduced has taken the space The PLC control has ison foot au
