Mawonekedwe a diagnostic kapena diagnostic scanner - nanga bwanji zowunikira magalimoto?

Ngakhale kuti magalimoto aposachedwa ali ndi zida zamagetsi ndipo mapangidwe ake ndi ovuta kwambiri kuposa kale, kuzindikira kuti palibe vuto sikuyenera kukhala kovuta. Izi zimafunanso mawonekedwe owunikira omwe angagwiritsidwe ntchito kuwerenga zolakwika mugawo lowongolera. Komabe, pali zida zingapo zotere, zina zimapereka zosankha zingapo, pomwe zina zimapereka chilichonse zotheka. Kodi mungapeze bwanji yoyenera kwa inu? Ndiye muyenera kudziwa chiyani za iwo? Chisankho choyenera chingakhale chiyani?

Kodi mawonekedwe owunikira magalimoto amagwira ntchito bwanji?

Chinsinsi chagona pa cholumikizira cha OBDII ("on-board diagnostics"). Ili ndi udindo wotumiza ma sign kuchokera kugalimoto yodzizindikiritsa yokha kupita ku chipangizo chotulutsa. Udindo woyika socket wamtunduwu unayambitsidwa m'magalimoto opangidwa kuyambira 1996 ku USA, komanso ku Europe kuyambira 2001. Choncho, magalimoto onse kuyambira 2000 zambiri okonzeka ndi cholumikizira chotero. Komabe, socket imodzi sikokwanira kuwerenga zizindikiro.

Kuzindikira zamagalimoto ndi woyesa

Zida zomwe zimakulolani kuti muwerenge zizindikiro zomwe zimatumizidwa ku cholumikizira cha OBDII ndi mawonekedwe ozindikira omwe amagwira ntchito molingana ndi protocol ya ELM327. Ichi ndi kachubu kakang'ono ka trapezoidal komwe kamalowetsedwa munjira. Onse cholumikizira palokha ndi pulagi amapangidwa m'njira kuti asasokoneze mbali za kulumikiza zipangizo. Chifukwa chake, wogwiritsa ntchito galimotoyo sayenera kukhala ndi vuto kuyiyika.

Chida chotsatira chomwe mungafune ndi foni yam'manja, piritsi, laputopu, kapena chipangizo china chomwe chimavomereza chizindikiro cha Bluetooth chotumizidwa ndi elm327. Kumbali inayi, ndikofunikira kuyikapo mapulogalamu omwe angawerenge zizindikiro ndikudziwitsa dalaivala za zolakwika zomwe zimawoneka pakompyuta yagalimoto. Komabe, ichi si chida chokha chomwe chingagwiritsidwe ntchito pozindikira magalimoto.

Kodi protocol ya ELM327 ndi chiyani? 

Protocol ya ELM327 ndi chida chofunikira komanso chosunthika chomwe chimagwira ntchito bwino ngati sikani yowunikira. Imawonetsa zidziwitso zoyambira monga ma code olakwika kapena data yoyendetsa. Komabe, kuti mudziwe zambiri komanso kukhala ndi chiwopsezo chachikulu pazidziwitso zamagalimoto, mutha kusankha mawonekedwe ena. Nthawi zambiri amaperekedwa kuzinthu zinazake kapena nkhawa.

Ndi autotester iti yomwe muyenera kusankha?

Ngati mukufuna kudziwa zambiri zazing'ono kwambiri, sankhani mawonekedwe odzipatulira ozindikira. 

1. Mwachitsanzo, kwa magalimoto a gulu la VAG, i.e. Audi, Mpando, Skoda, Volkswagen, mudzafunika gawo la dzina. 
2. Kwa magalimoto a BMW, awa ndi, mwachitsanzo, Carly ndi K + DCAN. 
3. Ngati ndinu mwini galimoto ya FCA, chisankho chabwino kwambiri chingakhale OBD2 VAG KKL kapena FIATECUSCAN.

Ndi chiyani chomwe chingayang'anidwe kudzera m'malo opangira matenda?

Kuthekera kwapamwamba kwamapulogalamu ozindikira omwe amalipidwa ndi mawonekedwe apadera amaposa kuthekera kwa mayankho onse. Pogwiritsa ntchito scanner yowunikira, mutha, mwa zina:

• kuyang'anira magawo ogwiritsira ntchito injini monga kutentha kozizira, kutentha kwa mafuta, kutentha kwa mpweya / mafuta osakaniza, kuthamanga kwa turbocharger, kuwerengera kwa lambda, kapena mphamvu ya batri;
• kuwerenga mndandanda wa zolakwika zomwe zimachitika chifukwa cha zosokoneza zomwe zapezeka ndi masensa ndikuzichotsa;
• kuyeza magwiridwe antchito agalimoto - mphamvu, torque, kugwiritsa ntchito mafuta nthawi yomweyo;
• Dziwani momwe machitidwe a munthu aliyense amagwirira ntchito, mwachitsanzo, ma air conditioning.
• sinthani magwiridwe antchito a machitidwe ena - nthawi yomwe kuwala kumayatsidwa chitseko chikatsekedwa, kumva kwa masensa amvula;
• sungani magwiridwe antchito a injini poyendetsa.

Mitundu yolumikizirana yama diagnostics agalimoto. Opanda zingwe matenda mawonekedwe

Kusankha sikuli kwakukulu kwambiri, chifukwa pali zipangizo pamsika zomwe zimagwira ntchito mu Bluetooth, Wi-Fi ndi machitidwe a chingwe. Opanda zingwe amagwiritsidwa ntchito nthawi zambiri pantchito zowunikira. Ndiwosavuta komanso osavuta kugwiritsa ntchito, safuna mawaya. Malingaliro okhudza mawonekedwe opanda zingwe nthawi zambiri amakhala abwino, ndipo madalaivala omwe amawagwiritsa ntchito tsiku ndi tsiku amakhutira.

Komabe, nthawi zambiri mawayilesi amawayilesi amakulolani kuti muwerenge zambiri mwachangu, ndipo nthawi zina mumapeza zambiri zomwe sizipezeka pamitundu yonse yopanda zingwe. Chifukwa chake ngati mukufuna kusanthula magwiridwe antchito a injini pafupipafupi ndikupeza zidziwitso zoyambira, mtundu wopanda zingwe ndizomwe mukufuna. Kuti mudziwe zambiri, sankhani makope a chingwe.

Ndi pulogalamu yanji yomwe mungagwiritse ntchito poyesa mayeso?

Pali mapulogalamu ambiri a Android, iOS ndi Windows. Iwo akhoza kugawidwa mu ufulu ndi kulipira. Nthawi zambiri izi ndi mapulogalamu omwewo ndi mayina omwewo, mwachitsanzo, makokedwe, Car Scanner, Piston, Dash Command, OBDeleven, OBD Mary, OBD Harry Scan. M'mapulogalamu aulere, mawonekedwe owunikira amawonetsa zidziwitso zochepa, koma nthawi zambiri amakupatsani mwayi wochotsa zolakwika zomwe zimawoneka mwa wowongolera ndikuwunika mosamala. Zolipidwa. Matembenuzidwe owonjezera adapangidwa kuti azitha kuyeza magawo ambiri ndikuwunikira mwatsatanetsatane.

Chifukwa chiyani kuli koyenera kuyika ndalama mu mawonekedwe ndikudzifufuza nokha?

Choyamba, kukhala ndi mawonekedwe a matenda ndi othandiza kwambiri. Nthawi iliyonse mukamayendetsa, mutha kuyang'anira momwe injiniyo imayendera ndikupeza zomwe zimayambitsa kusokonekera. 

Ma diagnostic interfaces ngati njira yopulumutsira ndalama? 

The matenda mawonekedwe adzakupulumutsirani ndalama wamakhalidwe. Tangoganizirani nthawi yomwe chizindikiro cha "check engine" chikuwonekera pa dashboard. Zingasonyeze mavuto ndi zolakwika zosiyanasiyana. Chophweka njira ndi kufika pafupi galimoto kukonza shopu, kumene inu kulipira 50-10 mayuro kwa utumiki kulumikiza matenda kompyuta ndi erasing zolakwa, ndi bwanji ngati mu sabata kapena awiri, ndipo choipitsitsa cha zonse, chimodzimodzi. tsiku mutayambitsanso injini, kodi vutolo limabwereranso? Pambuyo maulendo angapo otere, mtengo wa mawonekedwe amalipira.

A munthu diagnostic mawonekedwe adzalola kuti bwererani cholakwika nokha. Mutha kuzigwiritsanso ntchito kuti muwunikire nthawi zonse machitidwe a injini, magwiridwe antchito ndikuwongolera makina anu osayendera makaniko. Inde, ndi bwino kukhala ndi chidziwitso chochepa cha makina ndi electromechanical kuti musinthe makonda agalimoto motere.

Diagnostic scanners ndi ma interfaces

Makina ojambulira magalimoto, mwachitsanzo, masikanidwe ozindikira, amapangidwira amakanika ndi anthu omwe amafuna. Kodi amasiyana bwanji ndi njira zowunikira?

Ma scanner ambiri amakhala ndi:

• wodzilamulira;
• kuthekera kowerenga deta kuchokera pagalimoto iliyonse;
• makandulo a magalimoto ambiri
• ndi kulola kulowererapo kwakukulu mu machitidwe a galimoto yopatsidwa. 

Nthawi zambiri, zojambulira zamagalimoto zimakhalanso ndi mapulogalamu ambiri, nkhokwe yathunthu komanso yosinthidwa mosalekeza yamakhodi olakwika ndi zina zambiri zamagalimoto. Ndi ma scanner a diagnostic, muli ndi njira zambiri zothetsera mavuto ndi kuthetsa mavuto. Komabe, choyipa chake ndi mtengo wogulira wokwera mosakayikira ndipo nthawi zambiri kufunikira kokonzanso zolembetsa.

Ndi mawonekedwe ati omwe mungasankhe - ELM327 kapena ina?

Ngati simukufuna kukumba m'misewu yakumbuyo ya woyang'anira makompyuta, ndiye kuti ELM327 yoyesa matenda a universal diagnostic ndiye chisankho choyenera. Idzakupatsirani zambiri zolakwika ndi magawo oyambira a injini. Mtengo wa chipangizo choterocho ndi makumi angapo a zloty, ngati tilankhula za zotsika mtengo kwambiri. Kuphatikizanso pulogalamu yamafoni yaulere ndipo mudzatha kuzindikira zovuta mgalimoto yanu popanda kanthu. Ngati zoyambira sizikugwirizana ndi inu ndipo mukuyang'ana zosankha zambiri, gwiritsani ntchito makina odzipatulira odzipatulira ndi pulogalamu yolipira, yopangidwa bwino. Ndiye mutha kudziwa zambiri zowonjezera zagalimoto yanu ndipo, chofunikira kwambiri, musinthe zambiri momwemo. Kwa zimango, zida zowunikira akatswiri zimalimbikitsidwa.
