Impendulo eqondile: kungani ukunyakaza okungalungile kuvela ngemva kokushintshwa?

Yiziphi izimpawu zokungasebenzi kahle okuvela ngemuva kokushintshwa kwenduku yokudlala?

Chaza ukunyakaza kahle. "I-Joystick ayisebenzi" ibanzi kakhulu ukuthi ingaxilonga noma i-RFQ. Izincazelo zezimpawu eziwusizo zihlanganisa:

• Ukuyisa i-lever phambili kuyala umsebenzi ongalungile we-crane.
• Umsebenzi olungile uhamba uye kolunye uhlangothi.
• I-eksisi eyodwa iyasebenza kuyilapho enye ingasebenzi.
• Ukunyakaza kuqala ngaphambi kokuba i-lever ishiye ukungathathi hlangothi.
• Ijubane lishintsha kungazelelwe noma alilingani ngokuhamba kwe-lever.
• Umshini ubika iphutha kuphela ngemva kokuba isibambo esisha sixhunyiwe.
• Umsebenzi womuntu ofile, nika amandla noma ukubuyisela maphakathi nendawo uziphatha ngendlela ehlukile.

I i-joystick yezimboni kanye nesigaba sokulawula isibambo ibonisa izinhlobo zezibambo ezimbalwa, kodwa ukufana okubonakalayo akusona isinqumo sokuhambisana. Uphawu ngalunye kufanele luxhunywe ku-eksisi ethile, isiqondiso, isimo sokusebenza kanye nesimo sokuxhuma.

Ochwepheshe bangasihlukanisa kanjani isibambo kusilawuli, izintambo kanye nesekhethi ye-hydraulic?

Sebenzisa ukuxilongwa kwesendlalelo ngesendlalelo. Okokuqala qinisekisa ukuhlonza nokufaka. Bese uqhathanisa isibambo sokuhlinzeka nokukhipha amasignali usebenzisa ulwazi olulungile lwesevisi kanye nempahla yokuhlola efanelekile. Okulandelayo hlola ukuqhubeka kwehhanisi, izikhindi, isimo sesixhumi nendawo yokuphina. Kuphela ngemva kokuba okokufaka okufinyelela kusilawuli sekuqondwe lapho okufanele ochwepheshe baphenye imephu yesilawuli, ukumisa noma impendulo ye-hydraulic engezansi kanye ne-actuator.

Leli oda livimbela amaphutha amabili abizayo: ukushintsha induku yokudlala yesibili lapho ihhanisi linephutha, noma ukushintsha amapharamitha wesilawuli ukuze kunxeshezelwe isibambo esingahambelani. Iphinde igweme ukusola ama-electronics lapho isignali yomyalo ilungile kodwa isekethe ye-hydraulic iphendula ngokungalungile.

Ingabe i-eksisi nesikhombisi-ndlela siyafana nesibambo sokuqala?

I-joystick ye-multi-axis kufanele ibonise ukunyakaza kwe-lever ebonakalayo emisebenzini elindelekile yomshini nezikhombisi-ndlela. Bhala ukuthi phambili, emuva, kwesokunxele nakwesokudla kusho ukuthini kusibambo sokuqala, okuhlanganisa noma yikuphi ukusonta, izinkinobho, izicupho noma ukunika amandla amaswishi. Bese ukhomba ukuthi yikuphi okukhipha esikhundleni okuhambisana nokunyakaza ngakunye.

Umkhiqizo ofana ne Isibambo sokulawula umphumela wehholo we-3-eksisi ingase ifanele izinhlelo zokusebenza ezidinga izimbazo eziningi, kodwa inombolo yezimbazo ayibonisi ukuthi imephu yesiqondiso sayo, isixhumi noma okukhiphayo kufana ne-crane yoqobo. Ungashintshi izikhonkwane ngokuhlola ngenkathi i-crane inokunyakaza okungavinjelwe.

Ingabe uhlobo lokuphumayo, ububanzi besiginali kanye ne-voltage yokunikezela kuyahambisana?

Ama-joystick embonini angase asebenzise inzwa ye-Hall-effect, ama-potentiometer, amaswishi noma inhlanganisela yemiphumela. Abalawuli bangalindela i-voltage ehlukene, yamanje, ukumelana, i-PWM, ukushintshwa noma okunye ukuziphatha kwesignali. Ukumiselela okukhiqiza isignali evumelekile yohlobo olungalungile noma ububanzi kungabangela ukusebenza okuhlehlisiwe, okulinganiselwe, okugcwele noma okunephutha.

Qhathanisa ukunikezwa okubhaliwe, umhlabathi, ubuchwepheshe bokuphumayo, ububanzi kanye nejika lejika layo yonke i-eksisi. Ngokwesibonelo, i EP/60B induku yokudlala yezimboni kanye nemodeli ye-Hall-effect imelela amathuba obuchwepheshe ahlukene; futhi akufanele imiselele enye ngaphandle kokuqinisekisa isixhumi esibonakalayo.

Ukuma kokungathathi hlangothi, i-deadband kanye nokubuyela emuva kuya maphakathi kukuthinta kanjani ukunyakaza?

Isilawuli sidinga ukubona isimo sokungathathi hlangothi esizinzile. Uma okukhiphayo okungena esikhundleni okuphakathi nendawo kuwela ngaphandle kwewindi elilindelekile, umshini ungase ubike iphutha, wenqabe ukunika amandla noma uyale ukunyakaza ngaphambi kokuba u-opharetha akuhlose. I-deadband ebanzi kakhulu ingenza impendulo izwakale ibambezelekile; eyodwa encane kakhulu ingenza ama-offsets amancane akhiqize ukunyakaza okungafuneki.

Hlola ukuthi i-lever ibuya ngokuzenzakalelayo phakathi nendawo nokuthi isignali ibuyela ngokungashintshi endaweni emaphakathi elindelekile. Futhi qinisekisa noma iyiphi inkinobho yokuvumela, umuntu ofile noma ehlobene nokuphepha ngokusebenzisa inqubo yesevisi egunyaziwe. Ungadluli le misebenzi ukuze wenze ukumiselela okungahambelani kubonakale kusebenza.

Kuyini ukulandelana kokuhlolwa kokusebenza okuphephile kwangemuva kokushintshwa?

Ukuhlolwa kufanele kulandele imiyalelo yesevisi yomkhiqizi we-crane futhi kwenziwe ngabasebenzi abaqeqeshiwe. Vikela indawo yokusebenza, susa imithwalo lapho kudingeka, nciphisa ukunyakaza okungenzeka, gcina ukulungela ukuma kwezimo eziphuthumayo futhi ugweme ukudlula izingidi.

1. Qinisekisa ubunikazi: Rekhoda amalebula okuqala nawashintshayo, ukukhwezwa, izixhumi nezingxenye zezinombolo.
2. Hlola ukufakwa: Hlola ukuhlala kwesixhumi, izikhonkwane ezilimele, uhlobo lwekhebula nokunyakaza kokubuyela maphakathi.
3. Qinisekisa amandla nokungathathi hlangothi: Qinisekisa ukunikezwa kanye nokuziphatha okungathathi hlangothi okuzinzile usebenzisa izinqubo ezigunyaziwe.
4. Hlola i-eksisi eyodwa ngesikhathi: Qhathanisa isiqondiso esiyaliwe nomsebenzi olindelekile ekuphenduleni okuphansi okulawulwayo okusebenzayo.
5. Qaphela ukuhamba ngokulinganayo: Bheka izindawo ezifile, ukweqa, ukugcwaliswa kwesikhala noma ukwehluleka ukubuyela kokungathathi hlangothi.
6. Thatha ukuxilongwa: Rekhoda amakhodi amaphutha, ukufundwa, imephu ye-eksisi nanoma yikuphi ukuchezuka.
7. Ikhishwa kuphela ngemva kokwamukelwa: Ungayibuyisi i-crane enkonzweni kuze kube uchwepheshe onomthwalo wemfanelo eqinisekisa ukusebenza okulungile nokuziphatha kokuphepha.

Yimiphi imininingwane okufanele iqhathaniswe ngaphambi kokuthi ku-odwe enye induku yokudlala?

Faka ilebula, i-lever, ukukhwezwa kanye nezithombe zokuxhuma; imephu yomsebenzi/yeziqondiso; amandla kagesi; ubuchwepheshe bokuphuma kanye nobubanzi lapho kubhalwe khona; izimpawu zokungathathi hlangothi kanye nokubuya; amakhodi wephutha; ukufundwa kwamasignali; ubuningi; kanye nemfuneko yokuhlolwa kwesampula yokuqala. Lokhu kukhiqiza ikhotheshini ewusizo kakhulu kunokucela “induku yokudlala ye-crane ebukeka ngendlela efanayo.”

Imibuzo evame ukubuzwa

Ingabe ukunyakaza okungalungile kufakazela ukuthi induku yokudlala entsha inesici?

Cha. Imephu ye-axis, i-pinout, ukuhambisana kwesignali, ukumiswa kwesilawuli, amaphutha e-harness kanye nokusabela kwe-hydraulic kungaveza izimpawu ezifanayo.

Ingabe izixhumi ezifanayo zingaba namaphinifa ahlukene?

Yebo. Ukulingana kwesixhumi esibonakalayo kufanele kulandelwe ukuqhathanisa kukagesi kwephini nephini.

Ingabe i-joystick ye-Hall-effect ingakwazi ukufaka induku yokudlala ye-potentiometer?

Kuphela uma ukunikezwa, uhlobo lokukhiphayo, ububanzi, ukuziphatha okungathathi hlangothi, ukuphina kanye nokulindelwe kwesilawuli kuqinisekiswa ukuthi kuyahambisana.

Kungani i-crane ihamba ngaphambi kokuba i-lever ihambe ingathathi hlangothi?

Okukhiphayo okumaphakathi, i-deadband, indlela yokubuyisela, ukulinganisa, izintambo noma ukuhumusha kwesilawuli kungase kungalungile. Misa ukusebenza futhi uqinisekise lezi zinkambu ngokuphephile.

Ingabe ochwepheshe kufanele bashintshe amapharamitha wesilawuli kuqala?

Cha. Qinisekisa ubunikazi besibambo esishintshayo, isignali namahhanisi ngaphambi kokushintsha amapharamitha angafihla ukungafani kwangempela.

Iluphi ukuhlolwa kokuqala okuphephe kakhulu ngemva kokufakwa?

Qala ngobunikazi, ukufakwa, ukuhlola amandla kanye nokungathathi hlangothi, bese uhlola i-eksisi eyodwa ngesikhathi ngaphansi kwezimo ezilawulwayo kanye nenqubo yomkhiqizi.

Iluphi ulwazi olusiza umphakeli ukuthi abone isibambo esifanele?

Ubunikazi bomshini kanye nenduku yokudlala, izithombe ezicacile, imephu ye-eksisi/umsebenzi, ukuhlinzeka, okukhiphayo kanye nedatha ye-pinout, izimpawu, ukufundwa nokuhlolwa kokwamukela okuhleliwe kuwusizo kakhulu.

Thumela ubufakazi bokuxilonga ukuze bubuyekezwe esikhundleni

Nikeza imodeli yomshini nenombolo yeserial, inombolo yengxenye yenduku yokudlala yoqobo, izithombe zelebula nesixhumi, i-eksisi nemephu yesikhombisi-ndlela, i-voltage yokuhlinzeka, imininingwane yokuphumayo lapho itholakala khona, ukuziphatha okungathathi hlangothi, amakhodi amaphutha, ukufundwa kwesignali, inani nemfuneko yokuhlola isampula ephephile. U-Jiemanda angasebenzisa lobu bufakazi ukuze abuyekeze izinketho ezitholakalayo zokubamba futhi ancome isicaphuna esilandelayo noma isinyathelo sokuqinisekisa. Thumela imininingwane nge- ikhasi lokubuza isibambo esikhundleni.
