Iyini i-OBD kanye nomsebenzi wayo ekuxilongweni kwezimoto
I-Pendahuluan
I-On-Board Diagnostics, noma i-OBD, iyindinganiso esetshenziswa ezinhlelweni zokulawula izimoto evumela abanikazi bezimoto noma ochwepheshe bezinsizakalo ukufinyelela isimo sezinhlelo ezahlukene zezimoto. Njengoba ubuchwepheshe bezimoto buthuthuka, i-OBD isuke enguqulweni elula yaya ohlelweni oluyinkimbinkimbi kakhulu, inikeza ulwazi oluningi olungasiza ekutholeni nasekulungiseni ukungasebenzi kahle kwezimoto. Lesi sihloko sizohlola i-OBD ngokujulile, ukuvela kwayo, kanye nemisebenzi yayo ehlukahlukene ekuxilongweni kwezimoto.
Umlando kanye Nokuvela Kwe-OBD
I-OBD I
I-OBD yethulwa okokuqala ngasekupheleni kwawo-1980 nasekuqaleni kwawo-1990 ngesistimu eyaziwa ngokuthi i-OBD I. Lolu hlelo lwaluqapha kakhulu ukukhishwa kwezimoto futhi lwaqinisekisa ukuthi izinjini zisebenza ngaphakathi kwezindinganiso zokukhishwa kwezimoto ezamukelekayo. Ngeshwa, i-OBD I yayinemikhawulo ngokwezindinganiso zokuxhuma kanye nezinqubo. Lokhu kwaholela ezinkingeni eziningi zokuhambisana nokusebenza, njengoba umenzi ngamunye wemoto esebenzisa uhlelo oluhlukile.
I-OBD II
Ngenxa yemikhawulo ye-OBD I kanye nesidingo sezindinganiso ezingcono, i-OBD II yathuthukiswa futhi yethulwa e-United States ngo-1996. I-OBD II yabhekana nezinkinga eziningi ezazibhekene nowandulelayo ngokunikeza indinganiso yendawo yonke yezixhumi kanye nezinqubo zokuxhumana. Lolu hlelo aluqapheli nje kuphela ukukhishwa kwegesi kodwa futhi luqapha nezinye izici ezahlukene zokusebenza kwenjini, okuhlanganisa isivinini semoto, isimo sokudlulisa, nokuningi. Ngaphezu kwalokho, i-OBD II iyakwazi ukurekhoda nokugcina amakhodi amaphutha (Amakhodi Ezinkinga Zokuxilonga, noma ama-DTC) angafundwa ngamadivayisi akhethekile okuxilonga.
Imisebenzi Eyinhloko ye-OBD
Ukuqapha Ukukhishwa Kwegesi
Omunye wemisebenzi eyinhloko ye-OBD ukuqapha uhlelo lokukhishwa kwegesi emotweni. Izinzwa emotweni zilandelela ukukhishwa kwegesi futhi ziqinisekise ukuthi zihlala ngaphakathi kwemingcele yokulawula. Uma kutholakala ukungafani, i-OBD izokwazisa umshayeli ngesibani esithi "Check Engine" kudeshibhodi.
Ikhodi Yephutha Isitoreji Nokufunda
I-OBD ingathola izinkinga ezahlukene zobuchwepheshe ezinhlelweni zezimoto. Uma kutholakala inkinga, uhlelo lugcina i-DTC (Directional Transmitter Disabled Code) engafinyelelwa ngethuluzi lokuxilonga. Le khodi ikhombisa indawo nohlobo lwephutha, okuvumela ochwepheshe ukuthi babone futhi balungise inkinga ngokushesha ngaphandle kokuyifuna ngesandla.
Idatha Yesikhathi Sangempela
I-OBD iphinde inikeze ukufinyelela kwedatha yesikhathi sangempela evela ezinzwa ezahlukahlukene emotweni. Le datha ifaka phakathi ulwazi ngesivinini semoto, isivinini senjini (RPM), izinga lokushisa lenjini, izinga likaphethiloli, nokuningi. Lokhu kuwusizo kakhulu ekuxazululeni izinkinga ezingase zenzeke ngenkathi imoto isebenza futhi kunikeza ulwazi olubalulekile ngesikhathi senqubo yokuxilonga.
Izinzuzo ze-OBD ekuxilongweni kwezimoto
Ukusebenza kahle
Enye yezinzuzo ezinkulu zokusebenzisa i-OBD ukusebenza kahle. I-OBD ivumela ochwepheshe ukuthi babone izinkinga ngokushesha ngaphandle kokuhlakaza izingxenye zemoto ngayinye. Lokhu konga isikhathi nemali ekulungiseni nasekulungiseni izimoto.
Akurasi
Ngokuthola kwayo okusheshayo nokugcinwa kwama-DTC, i-OBD inikeza indlela enembile yokuthola umthombo wenkinga. Lokhu kunciphisa amathuba okuba namaphutha ngesikhathi senqubo yokulungisa futhi kuqinisekisa ukuthi imoto ibuyiselwa esimweni sayo esifanele ngokushesha okukhulu.
Ukuqapha Okuvimbelayo
Umsebenzi wokuqapha ku-OBD uphinde uvumele abanikazi bezimoto ukuthi bathathe izinyathelo zokuvimbela ngaphambi kokuba izinkinga zengozi zibe zimbi kakhulu. Isibonelo, uma uhlelo luthola inkinga ohlelweni lokupholisa, umnikazi wemoto angathatha isinyathelo ngaphambi kokuba injini iqale ukushisa ngokweqile, okungadala umonakalo omkhulu.
Ukuqaliswa Kobuchwepheshe Bamuva
Njengoba ubuchwepheshe buthuthuka, i-OBD iye yathuthuka yaba yinkimbinkimbi futhi yahlanganiswa nezinhlelo zamakhompyutha ezimoto zesimanje. Nazi ezinye zezinguquko zakamuva zobuchwepheshe ku-OBD:
I-OBD III
I-OBD III iyisinyathelo esikhuphukayo kune-OBD II, yize kungekho zindinganiso zomhlaba wonke ezisetshenzisiwe. Umqondo ngemuva kwe-OBD III ukuthuthukisa ukuqapha ukukhishwa kwegesi ngesikhathi sangempela nokuthuthukisa impendulo yokwephulwa kokukhishwa kwegesi. Uhlelo luvumela ukulawula okukude kanye ne-telemetry ukubika isimo sohlelo lokukhishwa kwegesi emotweni ngqo kuziphathimandla noma kumnikazi wemoto, okwenza kube nokuqapha okuqinile kanye nokuphoqelelwa kwemithetho yokukhishwa kwegesi ngempumelelo.
Ukuhlanganiswa ne-IoT
Ubuchwepheshe be-inthanethi yezinto (IoT) buthinte izici eziningi zokuphila kwethu, okuhlanganisa nezinhlelo ze-OBD. Izinhlelo ze-OBD zesimanje manje sezingakwazi ukuxhuma ezinhlelweni zokusebenza ze-smartphone nge-Bluetooth noma i-Wi-Fi, okuvumela abanikazi bezimoto ukuthi baqaphe isimo sezimoto zabo kalula. Izinhlelo zokusebenza ze-OBD zingabonisa idatha yesikhathi sangempela, zigcine umlando wedatha, futhi zinikeze nezincomo zokulungisa.
Izimoto Ezizimele
Uma kukhulunywa ngezimoto ezizisebenzela zona, i-OBD idlala indima ebalulekile ekuqinisekiseni ukuthi zonke izinhlelo zisebenza kahle futhi zisebenza ngokwezindinganiso. I-OBD ingasiza ekuqapheni ukusebenza kwezinzwa nezinhlelo zokulawula ezisekela ubuchwepheshe obuzisebenzela zona, iqinisekise ukuphepha nokuthembeka kwalezi zimoto.
I-Penutup
I-On-Board Diagnostics (OBD) iyintsha ebaluleke kakhulu ezweni lezimoto lanamuhla. Kusukela ekuqaleni kwayo okuthobekile njengethuluzi elilula lokuqapha izinhlelo zokukhishwa komoya, i-OBD iguquke yaba uhlelo oluyinkimbinkimbi olunikeza izinzuzo eziningi kubanikazi bezimoto kanye nochwepheshe bezinsizakalo. Ikhono layo lokubona izinkinga kusenesikhathi, ukunemba kwayo kokuxilonga, kanye nokusebenza kwayo kahle ekulungiseni kwenza i-OBD ibe ithuluzi elibalulekile ekunakekelweni kwezimoto.
Ngokuthuthuka okuqhubekayo kobuchwepheshe, indima ye-OBD izoba yinto ebaluleke kakhulu ekuqinisekiseni ukuthi izimoto zihlala ziphephile, zisebenza kahle, futhi zihambisana nemithethonqubo esebenzayo. Kubanikazi bezimoto, ukuqonda imisebenzi nezinzuzo ze-OBD kungabasiza ukuba bagcine izimoto zabo zisesimweni esihle, bagweme izindleko zokulungisa ezingadingekile, futhi baqinisekise ukuthi izimoto zabo zinobungani nemvelo.
