Kuyini nokuthi yikuphi ongakwenza ngakho
Kusukela kokusungulwa kwamakhompiyutha e-intanethi ngasekupheleni kwawo-1970 kanye nasekuqaleni kweminyaka yama-1980, sekuye kwaba nzima nakakhulu ukuthungatha imithi emthunzini kanye nabakwa-DIY abahlakaniphile ukuba basebenzise izimoto zabo, kodwa i-chip encane ebizwa ngokuthi i-ELM327 microcontroller iyasiza ukushintsha lokho.
Kuwo wonke ama-1980 kuya phezulu kuze kube maphakathi nawo-1990, wonke umenzi wemoto wayenezindinganiso zakhe kanye nemigomo, futhi kwakuyikhanda langempela ngisho nochwepheshe bezobuchwepheshe ukuhambisana nakho konke. Lokho kwaqala ukushintsha ngokusungulwa kwe- OBD-II , okuyinto ejwayelekile eyenziwe yi-automakers emhlabeni jikelele, kodwa amathuluzi wokuhlola okusebenzayo angadala amashumi ezinkulungwane zamaRandi.
Kuze kube yiminyaka embalwa eyedlule, ngisho nekhodi eyisisekelo nabafundi bezinombolo ngokuvamile badla amakhulu ezinkulungwane zamaRandi. Amadivaysi alula angakwazi ukufunda nokucacisa amakhodi, kepha ngokuvamile awazange anikeze ukufinyelela kuma-PID angasiza kakhulu ekuhloleni izinkinga zokuqhuba nezinye izinkinga.
I-ELM327 ehlelwe yi-microcontroller yinkombinkimbi encane, ephansi kakhulu ebiza izindleko ezisiza ibhuloho lelo gap. Amadivaysi asebenzisa le microcontroller, njenge- scanner ye - Yongtek ELM327 ye-Bluetooth , namanje ayibambeli ikhandlela kumathuluzi wokuhlola ama- professional, kodwa abeka ulwazi oluningi ngezandla zabakwa-DIYers.
I-ELM327 isebenza kanjani?
I-microcontroller ye-ELM327 isebenza njengebhuloho emkhatsini wekhompiyutha ebhodini emotweni yakho ne-PC yakho noma idivayisi egcinwe ngesandla. U-ELM327 uyakwazi ukuxhumana nesistimu ye-OBDII bese edlulisela idatha nge-USB, i-WiFi, noma i- Bluetooth , kuye ngokuqaliswa okukhethekile.
I-ELM327 isekela inqubo ehlukahlukene ye-SAE ne-ISO, futhi amadivayisi asemthethweni e-ELM327 akwazi ukuxhumana nanoma iyiphi imoto ye-OBDII. Umyalo osetshenziswe ngu-ELM327 awufani nalokho okubekwa khona kwe-Hayes, kodwa kufana kakhulu.
Yini engingayenza nge-ELM327?
Ungasebenzisa idivayisi ye-ELM327 ukusiza ukuxilonga imoto yakho noma iloli, kodwa ngokujwayelekile uzodinga enye ihadiwe kanye nesofthiwe. Amadivayisi we-ELM327 angaxhunyaniswa kumakhompiyutha , ama-smartphone, amaphilisi, namanye amadivayisi ngezinhlobo ezahlukene zezindlela. Izindlela ezintathu eziyinhloko zihlanganisa:
- Ukuxhumeka kwe-USB okuhlangene
- Okukhethwa kakhulu okuhambisana kakhulu.
- Okungabizi kakhulu ngenxa yomsakazo ongenazintambo.
- Ayikho inhlobo yokuxhumeka kwehla.
- Ikhebula lingangena endleleni.
- Ukuxhumana okungenantambo kwe-WiFi
- Iyahambisana namadivayisi amaningi kune-Bluetooth.
- Ezibizayo.
- I-Bluetooth
- Okungabizi kakhulu.
- I-Bluetooth iyatholakala kumadivayisi amaningi.
- Akuhambisani namanye amadivaysi, njenge-iPhones.
Uma une-PC noma idivayisi ye-Android, noma yikuphi kulabo kuzosebenza ngokujwayelekile. Uma unayo i-iPhone noma i-iPad, cishe ngeke ukwazi ukusebenzisa idivayisi ye-Bluetooth ELM327 ngenxa yokuthi iOS isebenzela isitaki se-Bluetooth. Amadivayisi we- jailbroken angasebenza, nakuba lokho kuthatha ingozi ethile.
I-ELM327 ingakunikeza ukufinyelela kwamakhodi wezinkinga futhi ikuvumela ukuthi ubuke ama-PID. Njengoba ukukhulumisana kube yi-bidirectional, i-ELM327 ingakuvumela futhi ukusula amakhodi ngemuva kokuthi ulungise inkinga. Izenzo eziqondile ongayenza kuzoxhomeka kudivayisi yakho ethize ye-ELM327 nesofthiwe oyisebenzisayo, kodwa ungase ukwazi ukubuka abaqaphi bokuzilungiselela kanye nedatha.
Qaphela ama-Clones namaPirates
Kukhona ama-clones amaningana nama-pirates emakethe, kanti abanye basebenza kangcono kunabanye. I-v1.0 yasekuqaleni yekhodi ye-ELM327 microcontroller ayikho ikhophi evikelwe i-Elm Electronics, eyabangela ukuba iphikisiwe. Amanye amadivaysi asebenzisa ikhodi endala ayishintshiwe ukuze abike ukuthi basebenzisa inguqulo yamanje, kanti abanye baze babike inguqulo entsha engekho okwamanje.
Amanye ama-clones angama-pirated azinzile, kanti amanye amabiza kakhulu. Kunoma yikuphi, ngisho nama-clones azinzile ayesekho ukusebenza okungeziwe okutholakala kuzo izinguqulo ezintsha zekhodi ELM327 esemthethweni.
Ukuskena ezinye izindlela ku-ELM 327
Uma ungathanda ukusebenzisa ithuluzi lokuskena elimele, kunezinketho ezehlukene eziwela ezinhlobonhlobo zamanani ahlukahlukene:
- Abafundi bekhodi elula
- Amandla okufunda nokuhlanza amakhodi kuphela.
- Amathuluzi wokuskena azinikezele
- Amayunithi ayisisekelo ahlinzeka ukufinyelela kwamakhodi nama-PID.
- Amayunithi athuthukile ahlanganisa ulwazi lokuxazulula inkinga.
- I-OBD-I scan scan
- Kubalulekile uma imoto yakho yakhiwe ngaphambi kuka-1996.
- Abanye basebenza ngokukodwa kwemoto eyodwa.
- Ezinye zihlanganisa i-adapters yokusetshenziswa ngezimoto eziningi.
Ngenkathi amadivaysi asebenzisa i-microcontroller ELM327 ngokuvamile ebiza kakhulu, indlela elula yokuskena amakhodi nokubuka i-PID, kunezimo lapho enye yezinketho ezingenhla izosebenza kangcono. Isibonelo, i-ELM327 isebenza kuphela ne-OBD-II, ngakho-ke ithuluzi lokuskena elingu-ELM327 ngeke lenze okuhle uma imoto yakho yakhiwe ngaphambi kuka-1996. Ngaphandle kokuba ungumshini ochwepheshe, idivayisi ye-ELM327 iyosebenza kahle kakhulu nezinye izimo.
