Chimene Iwo ali ndi Zimene Inu Mungachite ndi Iwo
Kuyambira pamene makompyuta oyambira pamapeto a zaka za m'ma 1970 ndi kumayambiriro kwa zaka makumi asanu ndi makumi asanu ndi atatu, ayamba kukhala ovuta kwambiri kuti azitha kugwiritsira ntchito mthunzi wamtengo wa mthunzi komanso oyendetsa galimoto kuti azigwira ntchito pa magalimoto awo, koma chipinda chochepa chotchedwa ELM327 microcontroller chikuthandizira kusintha.
Kwa zaka za m'ma 1980 mpaka m'ma 1990, wokonza galimoto aliyense anali ndi miyezo yake komanso ndondomeko yake, ndipo inali mutu weniweni kwa akatswiri amisiri kuti apitirize nazo zonsezo. Izi zinayamba kusintha ndi kukhazikitsidwa kwa OBD-II , yomwe ndiyomwe yakhazikitsidwa ndi automakers kudutsa mdziko lonse lapansi, koma zipangizo zamakono zikhoza kudula madola masauzande ambiri.
Mpakana zaka zingapo zapitazo, ngakhale owerenga komanso owerenga deta nthawi zambiri amawononga ndalama zambiri. Zida zosavuta kuziwerenga zimatha kuwerenga ndi kuchotsa ma code, koma nthawi zambiri sankakupatsani mwayi wa PIDs omwe angakhale othandiza kwambiri pozindikira mavuto omwe angayendetseko ndi zina.
The ELM327 yokonza microcontroller ndi njira yaying'ono, yotsika mtengo yomwe imathandiza phokosolo. Zipangizo zomwe zimagwiritsa ntchito microcontroller, monga Yongtek ELM327 Bluetooth scanner , sitingathe kuyika makandulo ku zida zogwiritsira ntchito, koma amaika zambiri zambiri m'manja mwa DIYers.
Kodi ELM327 Zimagwira Ntchito Bwanji?
The ELM327 microcontroller imagwira ntchito ngati mlatho pakati pa makompyuta oyendetsa galimoto yanu ndi PC yanu kapena chipangizo chogwiritsira ntchito. ELM327 amatha kuyankhulana ndi dongosolo la OBDII ndikutsitsa deta kudzera USB, WiFi, kapena Bluetooth , malingana ndi kukhazikitsidwa kwake.
ELM327 imathandiza maofesi osiyanasiyana a SAE ndi ISO, ndipo zipangizo zovomerezeka za ELM327 zimatha kuyankhulana ndi galimoto iliyonse ya OBDII. Lamulo limene linagwiritsidwa ntchito ndi ELM327 silili lofanana ndi lamulo la Hayes, koma ndi ofanana kwambiri.
Kodi Ndingatani Ndili ndi ELM327?
Mukhoza kugwiritsa ntchito chipangizo cha ELM327 kuti muthandize kupeza galimoto yanu kapena galimoto, koma nthawi zambiri mumasowa zipangizo zina. Zipangizo za ELM327 zingagwirizane ndi makompyuta , matelefoni, mapiritsi, ndi zipangizo zina kudzera njira zosiyanasiyana. Njira zitatu zoyambirira zikuphatikizapo:
- Kugwirizana kwa waya wounikira
- Ambiri omwe amagwirizana nawo.
- Zosakwera mtengo chifukwa cha radiyo yopanda waya.
- Palibe mwayi wogwirizana.
- Chingwecho chimatha kufika panjira.
- Wopanda WiFi mauthenga
- Zimagwirizana ndi zipangizo zambiri kuposa Bluetooth.
- Zamtengo wapatali.
- bulutufi
- Zosafunika kwenikweni.
- Bluetooth imapezeka pazinthu zambiri.
- Zotsutsana ndi zipangizo zina, monga ma iPhones.
Ngati muli ndi PC kapena Android chipangizo, aliyense wa iwo adzagwira ntchito. Ngati muli ndi iPhone kapena iPad, mwina simungagwiritse ntchito chipangizo cha Bluetooth ELM327 chifukwa cha momwe iOS imagwirira paketi ya Bluetooth. Zipangizo zamakono zingagwire ntchito, ngakhale zili ndi vuto linalake.
ELM327 angakupatseni mwayi wopeza mavuto ndikukulolani kuwona PIDs. Popeza kuti kuyankhulana kumakhala kozungulira, ELM327 ikhoza kukulolani kuti muchotse ma code mutatha kukhazikitsa vuto. Zochita zomwe mungathe kuchita zidzadalira pa chipangizo chanu cha ELM327 ndi mapulogalamu omwe mumagwiritsa ntchito, koma mukhoza kuyang'anitsitsa kuyang'anira ndi ma data ena.
Chenjerani ndi ma Clones ndi Pirates
Pali ma clones angapo ndi owopsa pa msika, ndipo ena amagwira ntchito bwino kuposa ena. Choyambirira v1.0 ya code ELM327 microcontroller sizinali zotetezedwa ndi Elm Electronics, zomwe zinapangitsa kuti pirated. Zida zina zomwe zimagwiritsira ntchito code yakaleyi zasinthidwa kuti ziwonetse kuti zikugwiritsidwa ntchito panopa, ndipo ena amalembanso kusintha kwatsopano komwe kulibe.
Mitsempha ina yoipitsidwa imakhala yosasunthika, ndipo ena ndi ngongole kwambiri. Mulimonsemo, ngakhale makonzedwe osakhazikika alibe ntchito yowonjezera yomwe imapezeka mu code yatsopano ya ELM327.
Kusinthanitsa Njira Zina za ELM 327
Ngati mungakonde kugwiritsa ntchito chida chojambulira cha standalone, pali njira zosiyanasiyana zomwe zingagwirizane ndi mitundu yosiyanasiyana ya mtengo:
- Owerenga makalata ophweka
- Amatha kuwerenga ndi kuchotsa ma code okha.
- Zida zojambulira
- Zigawo zoyambirira zimapereka mwayi wopezera mauthenga ndi PIDs.
- Maofesi apamwamba akuphatikizapo mauthenga okhudzana ndi mavuto.
- OBD-Ndikuyang'ana zipangizo
- Zofunikira ngati galimoto yanu inamangidwa pasanafike 1996.
- Ena amagwiritsa ntchito galimoto imodzi yokha.
- Zina zimaphatikizapo adapters kuti agwiritsidwe ntchito ndi magalimoto ambiri.
Ngakhale zipangizo zomwe zimagwiritsira ntchito chipangizo chamagetsi cha ELM327 ndizovuta kwambiri, njira yosavuta yowunikira ma code ndi kuyang'ana PIDs, pali zochitika pamene imodzi mwazimenezi zingagwire ntchito bwino. Mwachitsanzo, ELM327 imagwira ntchito limodzi ndi OBD-II, choncho chipangizo cha ELM327 sichingakupindulitseni ngati galimoto yanu inamangidwa pasanafike chaka cha 1996. Pokhapokha mutakhala makina opanga, chipangizo cha ELM327 chidzagwira bwino kwambiri zochitika zina.
