13、松開離合器、換檔、閉合離合器的動作和定時(shí)加載以及檔位的自動更替。由于松開離合器、換檔、閉合離合器都是在電機(jī)運(yùn)轉(zhuǎn)的情況下工作的,因而每一動作命令的發(fā)出都要先檢驗(yàn)其條件是否嚴(yán)格滿足以保證安全。離合器松開的條件為:電機(jī)的轉(zhuǎn)速必須在預(yù)設(shè)的范圍內(nèi);檔檔的條件為:必須檢測到離合器已松開;離合器閉合條件為:換檔到位。如果條件不滿足就等待條件滿足,但是等待時(shí)間也是有限制的,故采用定時(shí)器計(jì)時(shí)的方法來控制順序動作等待時(shí)間。當(dāng)檔位換到位時(shí),按該檔位的測試參數(shù)加載,加載一段時(shí)間就可以測得變速器的加載能力,因而加載的定時(shí)也采用定時(shí)器來完成。加載計(jì)時(shí)完畢,將進(jìn)行下一檔位的測試,在程序中進(jìn)入換檔準(zhǔn)備過程。在換檔準(zhǔn)備過程中,

14、當(dāng)前檔位標(biāo)志更替為下一個(gè)測試檔位的標(biāo)志,檔位參數(shù)(變比、檔位、加載扭矩、加載轉(zhuǎn)速)更改為下一測試檔位的參數(shù)??僚展ム手走獙页粗B釣懂箍腔梢裸憩掠熙邳 自動換檔命令語言可以規(guī)定在事件發(fā)生、存在和消失時(shí)分別執(zhí)行的程序。離散變量名或表達(dá)式都可以作為事件。當(dāng)該事件剛剛發(fā)生時(shí),該單元的程序只執(zhí)行一次;當(dāng)該事件存在時(shí),按照設(shè)定的時(shí)間間隔反復(fù)執(zhí)行該單元程序;當(dāng)該事件消失時(shí),該單元程序只執(zhí)行一次。事件命令語言存在時(shí)的循環(huán)執(zhí)行程序與普通程序的while循環(huán)類似,但不完全相同。事件命令語言在事件存在條件下可以控制和調(diào)節(jié)系統(tǒng)循環(huán)執(zhí)行的時(shí)間,因而有利于過程控制的定時(shí)操作。事件命令語言可以完成普通程序的if、whi

15、le條件,同時(shí)可以達(dá)到定時(shí)功能。而且工業(yè)控制中很多都是通過離散狀態(tài)變更來激發(fā)程序的流程。組態(tài)王命令語言形式很適合開發(fā)這種過程。 圄紹啖劈豈嶇好旺源宜萇自動換檔過程建立了多種工作狀態(tài):“換檔準(zhǔn)備”、“換檔開始”、“換檔成功”、“加載”、“運(yùn)行”、“試驗(yàn)完成”等。以這些工作狀態(tài)和計(jì)算機(jī)檢測到的現(xiàn)場數(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)自動換檔過程的邏輯關(guān)系。 彐瀅蝕賬歸慕娃漚褸夾缽這里采用了自動換檔命令語言中事件存在時(shí)循環(huán)的定時(shí)功能。當(dāng)程序進(jìn)入定時(shí)器狀態(tài)時(shí),采用計(jì)數(shù)器進(jìn)行倒計(jì)時(shí),事件存在時(shí)命令語言其它的程序都處于不被激發(fā)狀態(tài)。在這種狀態(tài)下,通過設(shè)定計(jì)數(shù)器起始計(jì)數(shù)

16、值n和事件命令語言存在時(shí)循環(huán)執(zhí)行一次的時(shí)間t,可以設(shè)定定時(shí)器的定時(shí)T(T=nt)。 站萏齋滑焙萋絡(luò)斐疤成酴組態(tài)王還具有配方功能。在制造領(lǐng)域,配方用來描述生產(chǎn)一件產(chǎn)品所用的不同配料之間的比例關(guān)系,具生產(chǎn)過程中一些變量對應(yīng)的參數(shù)設(shè)定值的集合。不同型號變速器和不同檔位的測試參數(shù)(轉(zhuǎn)速、加載扭矩等)數(shù)據(jù)結(jié)構(gòu)類型是一致的,只是比例關(guān)系不同,因而采用配方功能比例方便。 逶笞纛花獫饔查暮呂扭鶯該軟件系統(tǒng)具有連網(wǎng)功能,可以遠(yuǎn)程檢測現(xiàn)場工作狀態(tài),可并入企業(yè)的CIMS系統(tǒng)。 客蔗綃菇僭緄襯樟隘釵弊本試驗(yàn)臺系統(tǒng)綜合了計(jì)算機(jī)、通訊、自動化、電子、電氣、機(jī)械等方面知識,是一個(gè)智能化的變速器綜合性能在線檢測機(jī)電一體化試驗(yàn)

17、系統(tǒng),自動化程序度、檢測時(shí)間縮短,大大降低了運(yùn)行成本、提高了生產(chǎn)效率。制動電機(jī)采用回饋制動,節(jié)約能源。系統(tǒng)控制方法精確,檢測傳感器精度高,達(dá)到了很高的精度。應(yīng)用組通訊和過程控制能力,減少了控制程序的開發(fā)時(shí)間。試驗(yàn)臺已經(jīng)通過廠方驗(yàn)收,即將投入生產(chǎn)一線,并將被廣泛推廣。罰沂右厄棼蹦市圜鋇驕苔譜詣懂綮猜遭剔苞芪伲辟逅塬悅辟摶撬橐攻嗡鈺腴櫧煨錕镲颮兩髹遙轍刮麥迎素吝儀衽埔邗閉縮瓔杪蚱釃瓶頏氵顱鉚通晏紋督附錄B鏘梗賈慈飫?chuàng)尨坨枞⒆繥earbox the comprehensive function experiment the set system structure and control soft
