【正文】 This system pletes an au to experiment, move to experiment from the function, alone shift gear experiment, the fatigue test and efficiency experiment. The calculator auto39。s plank card munication method with PLC munication among them, set king with change the machine munication adoption set the king39。The clutch shuts to match a condition for:Shift gear condition the dissatisfied foot wait for a condition satisfy, but wait for time also having restriction, past adoption in fixed time method for machine to account to control in proper order ction to wait for the file changes to, the test parameter that press that file adds to carry, adding to carry a period of time can measure the gearbox add the ability of carry, as a result add to carry of also adopt in fixed time in fixed time a machine to to carry to account plete, will carry on the test of the next file, enter to shift gear to prepare process in the the period of shifting gear to prepare, the current file the marking substitute for the marking of the next test file, the file the parameter(change a ratio,file,add to carry to twist and add to carry to turn soon) change for descend one parameter of the test file. The automatic file changes process Set king the affairs order language can rule at the affairs take place,existence and disappear carry out respectively of change the quantity or expression types and can be an that affairs just took place, the procedure of that unit carried out once。s system has the function of connect, can with the long range examination the spot work appearance, can merge into the CIMS system of the business enterprise. Experimented the pedestal system to synthesize a calculator, munication, automation,electronics,electricity,machine originally etc. the aspect knowledge is a gearbox the prehensive function online examination machine electricity integral whole that an intelligence turn to turn on trial system, the automation procedure degree,examine time to shorten, lowered to circulate cost and raised to produce an efficiency to move the electrical engineering adoption feedback system to move, economize system controls the method precision, the examination spreads the feeling machine accuracy high, e to a very high set the munication with strong king and process control an ability, reducing to control procedure of development the pedestal has already passed factory a square to check before acceptance, will soon throw in to produce a glimmer of, and will be expanded extensively. 。When that affairs disappear, the unit39。s loosenning the condition for open is:The electrical engineering turns and has to be in the preestablished scope soon。s interface development systems can develop vivid interface for various control mode, very image, experiment process automatically is the key of this software system, past the following only to experiment to carry on a discussion automatically. Connect a people39。The ③ experiments the pedestal machine electricity the part takes calculator as center, controling software according to the spot data and current work appearance control system of process,allow to harm an allotment,the instruction send out and break down examination etc.。 (2)The test data statement and test and break down examine a patient of interface amity。The ③ gearbox manipulate(synchronous machine) the test of the function。The movement parameter can actually the hour show。試驗(yàn)臺(tái)已經(jīng)通過(guò)廠方驗(yàn)收，即將投入生產(chǎn)一線，并將被廣泛推廣。 本試驗(yàn)臺(tái)系統(tǒng)綜合了計(jì)算機(jī)、通訊、自動(dòng)化、電子、電氣、機(jī)械等方面知識(shí)，是一個(gè)智能化的變速器綜合性能在線檢測(cè)機(jī)電一體化試驗(yàn)系統(tǒng)，自動(dòng)化程序度、檢測(cè)時(shí)間縮短，大大降低了運(yùn)行成本、提高了生產(chǎn)效率 。 組態(tài)王還具 有配方功能。以這些工作狀態(tài)和計(jì)算機(jī)檢測(cè)到的現(xiàn)場(chǎng)數(shù)據(jù)組合構(gòu)成不同的事件，再以這些不同的事件之間相互激發(fā)、轉(zhuǎn)換的邏輯關(guān)系實(shí)現(xiàn)自動(dòng)換檔過(guò)程的邏輯關(guān)系。事件命令語(yǔ)言可以完成普通程序的 if、 while條件，同時(shí)可以達(dá)到定時(shí)功能。離散變量名或表達(dá) 式都可以作為事件。當(dāng)檔位換到位時(shí)，按該檔位的測(cè)試參數(shù)加載，加載一段時(shí)間就可以測(cè)得變速器的加載能力，因而加載的定時(shí)也采用定時(shí)器來(lái)完成。 自動(dòng)換檔過(guò)程的實(shí)現(xiàn) 自動(dòng)換檔過(guò)程流程圖 自動(dòng)換檔過(guò)程流程圖如圖 4所示 自動(dòng)換檔過(guò)程要完成松開(kāi)離合器、換檔、閉合離合器的動(dòng)作和定時(shí)加載以及檔位的自動(dòng)更替。 計(jì)算機(jī)通過(guò)檢測(cè)現(xiàn)場(chǎng)數(shù)據(jù)，根據(jù)任務(wù)規(guī)劃狀態(tài)向 PLC 和變頻器發(fā)送相應(yīng)的控制指令。 計(jì)算機(jī)通過(guò)檢測(cè)現(xiàn)場(chǎng)數(shù)據(jù)，根據(jù)任務(wù)規(guī)劃狀態(tài)向 PLC 和變頻器發(fā)送相應(yīng)的控制指令。由于自動(dòng)試驗(yàn)過(guò)程是本軟件系統(tǒng)的關(guān)鍵，故以下僅對(duì)自動(dòng)試驗(yàn)進(jìn)行討論。單獨(dú)換檔是應(yīng)廠家要求對(duì)某一指定檔位進(jìn)行試驗(yàn)。 本系統(tǒng)從功能上完成了自動(dòng)試驗(yàn)、手動(dòng)試驗(yàn)、單獨(dú)換檔試驗(yàn)、疲勞試驗(yàn)和效率試驗(yàn)。 系統(tǒng)工作原理 系統(tǒng)采用雙電機(jī)模擬汽車(chē)工況，其中驅(qū)動(dòng)電機(jī)通過(guò)變頻器的速度閉環(huán)控制模擬汽車(chē)的驅(qū)動(dòng)機(jī)構(gòu)，加載電機(jī)通過(guò)變頻器的扭矩閉環(huán)控制模擬汽車(chē)加載。工作時(shí)，加載電機(jī)工作在發(fā)電狀態(tài)下，能量回饋到電網(wǎng)，大大節(jié)約了能源。 試驗(yàn)臺(tái)機(jī)電部分是本系統(tǒng)是最終執(zhí)行機(jī)構(gòu)，完成將變速器驅(qū)動(dòng)到相應(yīng)轉(zhuǎn)速和加載扭矩，以達(dá)到特定測(cè)試工況。它的基本思路是利用 dq旋轉(zhuǎn)坐標(biāo)變換，將定子電流分成勵(lì)磁電流 id1和轉(zhuǎn)矩電流，在調(diào)速過(guò)程中保持轉(zhuǎn)子磁鏈不變，即 id1為常數(shù)，此時(shí)交流電機(jī)調(diào)速原理與直流電機(jī)相同。控制部分還包括變頻器、現(xiàn)場(chǎng)數(shù)據(jù)采集卡（ PCL818L）、 PLC控制器。 2 系統(tǒng)體系結(jié)構(gòu) 系統(tǒng)要求 廠方要求
