Izvo Zvazvo uye Zvaunogona Kuita Nazvo
Kubvira pakatanga makombiyuta ekubvira mumakore ekuma1970 nekutanga kwema1980, zvave zvichinyanya kuoma mumvuri-miti mechanics uye vasina njere DIYers kuti vashande pamotokari dzavo, asi chipfupi chinonzi ELM327 microcontroller chiri kubatsira kuchinja icho.
Mukuma1980 nekukwira kusvika pakati pemakore ekuma 1990, mutadzi wega wega wega aive nemitemo yake uye zvigadziro, uye yaiva musoro chaiwo kune vadzidzisi veyanyanzvi kuti varambe vaine zvose. Izvozvo zvakatanga kuchinja nekusvitsa kweBDD-II , iyo inowanikwa yakashandiswa nema automakers pasi rose, asi nyanzvi yekuongorora zvigadzirwa zvinogona kutengesa makumi ezviuru zvemadhora.
Kusvikira makore mashomanana adarika, kunyange nheyo dzekodhi uye vaverengi vekuda kazhinji vanodhura mazana emadhora. Zvigadziri zviduku zvinogona kuverenga uye kuchenesa makodhi, asi kazhinji havana kupa chero upi zvake kuPIDs iyo inogona kubatsira zvikuru pakuongorora zvinetso zvekuendesa uye zvimwe zvinhu.
IElm327 yakagadzirirwa microcontroller chirongwa chiduku, chisinganyanyi kudhura chinobatsira bhiriji iyo inopera. Mazano anoshandisa microcontroller iyi, yakafanana neYongtek ELM327 Bluetooth scanner , haichengetedzi mwenje kune unyanzvi hwokushandisa scan, asi vanoisa ruzivo rwakanyanya mumaoko a DIYers.
Iko ELM327 Inoshanda Sei?
Iyo microcontroller ye ELM327 inoshanda se bhiriji pakati pemakombiyuta ari mukati memotokari yako uye PC yako kana chipangizo chekuchengetedza. ELM327 inokwanisa kutaurirana neBDDII uye inotumirazve data ne USB, WiFi, kana Bluetooth , zvichienderana nekushandiswa kwatinoitwa.
ELM327 inotsigira nhamba dzakasiyana dzakasiyana dzeSAE neIO protocols, uye mazvibvumirano eEl327 anokodzera anokwanisa kutaurirana nemoto chero ipi zvayo yeBDDII. Mutemo wakashandiswa naElm327 hauna kufanana neHayes murairo wakaiswa, asi zvakafanana.
Ndingaitei NeEl327?
Iwe unogona kushandisa imwe ye ELM327 kuti ubatsire kutsvaga motokari yako kana kuti rori, asi iwe unowanzodikanwa zvimwe zvinyorwa uye software. ELM327 zvigadzirwa zvinogona kushamwaridzana nemakombiyuta , mafoni, mahwendefa, nemamwe magadzirirwo nenzira dzakasiyana siyana. Nzira idzi nhatu dzinosanganisira:
- USB yakakomberedzwa
- Yakawanda inowanikwa yakawanda.
- Zvimwe zvisingabatsiri pamusana pemhepo isina mhepo.
- Hapana mukana wekubatana kwepabonde.
- Iyo cable inogona kupinda munzira.
- Wireless WiFi connections
- Inopindirana nemamwe mafaira kupfuura Bluetooth.
- Dhura.
- Bluetooth
- Zvimwe zvisingabatsiri.
- Bluetooth inowanikwa pane zvakawanda zvigadzirwa.
- Inopesana nemamwe madivayiri, akaita sePhones.
Kana uine PC kana Android device, chero ipi zvayo inowanzoshanda. Kana iwe une iPhone kana iPad, zvichida haungakwanisi kushandisa bluetooth ELM327 device nemhaka yekuti iyo iOS inobata sei bhakiti reBluetooth. Zvigadzirwa zvejeri zvinogona kushanda, kunyange izvo zvinotakura zvimwe zvengozi.
ELM327 inogona kukupa kuti uwane matambudziko ematambudziko uye inokubvumira kuti uone PIDs. Sezvo kutaurirana kuri kuwirirana, ELM327 inogonawo kukubvumira kubvisa magwaro mushure mokunge makagadzirisa dambudziko. Izvo zviito zvakananga zvaunogona kuita zvinotarisa pane imwe yako ELM327 device uye software yauri kushandisa, asi iwe unogonawo kuona maonero ekugadzirisa uye mamwe mashoko.
Ngwarira maChones uye Pirates
Kune huwandu hwemakoni uye vashandi pamusika, uye vamwe vanoshanda zviri nani kudarika vamwe. Yepakutanga v1.0 ye code ELM327 microcontroller yakanga isiri iko yakachengetedzwa neElm Electronics, iyo yakaita kuti iiswe pirated. Zvimwe zvishandise zvinoshandisa iyo code yekare yakashandurwa kurondedzera kuti vari kushandisa shanduro yemazuva ano, uye vamwe vanoparidza shanduro itsva iyo isati yambovapo.
Mamwe mapiritsi ane pirated akatsiga, uye mamwe akazara zvikuru. Chero mamiriro ose ezvinhu, kunyange mavharesi akachengeteka haana humwe hutano hunowanikwa mune zvitsva zvitsva zvekodzero ye ELM327 code.
Kunyora Zvimwe Zvimwe kune ELM 327
Kana iwe uchida kushandisa shandari ye scanal, pane zvingasarudzwa zvakasiyana siyana zvinowira mumhando dzakasiyana-siyana dzakasiyana-siyana:
- Simple reader code
- Unokwanisa kuverenga uye kuchenesa mazano chete.
- Zvishandiso zvinotsvakirirwa zvokushandisa
- Zvikamu zvekutanga zvinopa kuwanika kwekodhi uye PIDs.
- Zvikwata zvakapfurikidza zvinosanganisira mashoko ekutsvaga matambudziko
- OBD-Ndinoongorora zvishandiso
- Zvinotarisirwa kana motokari yako yakavakwa kare 1996.
- Vamwe vanoshanda nechitunha chimwe chete chemotokari.
- Zvimwe zvinosanganisira adapters kuti ishandiswe nemotokari yakawanda.
Kunyange zvazvo zvishandiso zvinoita shanduro yeElm327 microcontroller inowanzoita mari-inoshanda, iyo nzira inonyanya kutsvaga mazano uye kuona PIDs, pane mamiriro ezvinhu apo chimwe chezvisarudzo pamusoro apa chichashanda zviri nani. Semuenzaniso, ELM327 inoshanda chete naB OBD-II, saka shanduro yeEl327 yekutarisa haizoiti chero ipi zvayo kudai motokari yako yakavakwa kare 1996. Kunze kwekuti iwe uri nyanzvi yemagetsi, imwe yeElm327 inozoshanda zvakanaka chaizvo mamwe mamiriro ezvinhu.
