imikhiqizo

Imojuli ye-Smart I/O inama-microcontroller ayo asebhodini. Amamojula achazwe kulesi sahluko amamojula e-Smart I/O. Ngesikhathi sokuqaliswa kwemojuli ehlakaniphile, isilawuli esincane semojuli siphendulela i-
I-LED icishiwe ngemva kokudlula ukuzihlola kwamandla futhi i-CPU isiqalise imojuli. I-LED ikhanyisiwe ukukhombisa iphutha le-I/O.

I-CPU iphinde itshele le mojula ukuthi yiliphi iqembu lezinga okufanele lisetshenziswe isiteshi ngasinye, kanye nanoma yiluphi ulwazi olukhethekile (njengohlobo lwe-thermocouple esimweni semojula ye-thermocouple). Ngesikhathi sokusebenza, i-CPU ibe isisakaza ngezikhathi ezithile "ukhiye" kuwo wonke amakhadi e-I/O, iwatshela ukuthi yimaphi amaqembu ezilinganiso okufanele abuyekezwe ngaleso sikhathi.

Ngalesi simiso sokuqala/sokhiye wokusakaza, imojula ngayinye ye-I/O isingatha ukuhlela kwayo kweqembu lesilinganiso ngokungenelela okuncane kwe-CPU. Lawa mamojula ahlakaniphile e-I/O aphinde abe nokutholwa kwamaphutha ku-inthanethi ekhadini kanye nokulinganisa okuzenzakalelayo/isinxephezelo. Ishaneli ngayinye yokufaka ine-voltage enembile
ireferensi. Kanye ngomzuzu, ngenkathi ingafundi okokufaka, isilawuli esincane esisebhodini sifunda lesi sithenjwa. I-microcontroller ibe isisebenzisa le datha efundwe kusukela kunkomba kagesi kukho kokubili ukutholwa kwephutha kanye nesinxephezelo/ukulinganisa okuzenzakalelayo kwezinga lokushisa.

Imikhawulo isethelwe ukufundwa okulindelekile lapho isilawuli esincane esisebhodini sifunda ireferensi ngayinye yamandla kagesi. Uma ukufundwa okutholiwe kungaphezu kwale mikhawulo, isistimu inquma ukuthi ishaneli yokufaka, i-A/D converter, noma ireferensi ye-precision-voltage yesiteshi ayisebenzi ngendlela efanele. Uma lokhu kwenzeka,
i-microcontroller ihlaba umkhosi leso siteshi njengesinephutha. I-CPU izobe isithatha noma yisiphi isenzo unjiniyela wohlelo lokusebenza asinikeze kuhlelo lohlelo.

Imojuli yokuphuma ehlakaniphile iqapha amandla kagesi okukhiphayo noma amandla esiteshi ngasinye futhi ixwayise isistimu uma kutholwa iphutha. Imojuli ye-I/O ngayinye inefuse kuyo. Le fuse iyabonakala futhi ingashintshwa ngokusikwa kwesembozo sepulasitiki semojuli. Uma i-fuse ishaywa, yishintshe nge-fuse yohlobo olufanayo nosayizi.

Umfanekiso 10-3 uwumdwebo webhulokhi wemojuli yesilawuli se-actuator eneziteshi ezimbili. Isiteshi ngasinye silawula i-actuator ehlanganisayo noma elinganiselayo, esebenza nge-hydromechanical noma ye-pneumatic. I-actuator ngayinye ingase ibe namadivayisi empendulo amabili okuma. Kunezinguqulo eziningana ezitholakalayo, futhi inombolo yengxenye yemojuli ikhombisa umthamo wamanje wokuphuma kwemojuli. Ikhebula le-MicroNet lowdensity discrete (grey) kufanele lisetshenziswe nale mojula. Ungasebenzisi ikhebula le-analog (emnyama).

Le module ye-Actuator Driver ithola ulwazi lwedijithali ku-CPU futhi ikhiqize amasignali amane alinganisiwe e-actuator-driver. Lawa masignali ayalingana futhi ububanzi bawo obukhulu bungu-0 kuye ku-25 mAdc noma 0 kuya ku-200 mAdc.

Umfanekiso 10-5 uwumdwebo webhulokhi wemojuli ye-Actuator Driver eneziteshi ezine. Uhlelo lubhala amanani okukhiphayo kumemori yezimbobo ezimbili ngokusebenzisa isixhumi esibonakalayo sebhasi le-VME. Isilawuli esincane sikala amanani sisebenzisa ama-conlibration constants agcinwe ku-EEPROM, futhi sihlela okuphumayo ukuthi kwenzeke ngesikhathi esifanele. I-microcontroller iqapha i-voltage ephumayo kanye neyamanje yesiteshi ngasinye futhi yazisa uhlelo lwanoma yisiphi isiteshi namaphutha okulayisha. Isistimu ingakhubaza abashayeli bamanje ngabanye. Uma kutholwa iphutha elivimbela imojuli ukuthi isebenze, nge-microcontroller noma isistimu, i-FAULT LED izokhanya.
