He aha ia a me ka mea e hiki iāʻoe ke hana me ia
Ma hope mai o ka hoʻokomoʻiaʻana o nā papahana lolo ma ka hopena o nā makahiki 1970 a me ka hoʻomakaʻana o nā makahiki 1980, ua lilo i mea paʻakikī loa i nāʻano mechanics pale a me nā mea DIYers inerpid e hana ma kā lākou mau kaʻa pono'ī, akā,ʻo kahi mea i kapaʻiaʻo ELM327 microcontroller e kōkua ana e hoʻololi i kēlā.
Ma waena o nā makahiki 1980 a hiki i ka waenakonu o nā makahiki 1990, ua loaʻa i nā mea hana kaʻa a me nāʻano kuʻuna, a he mea maʻamau loa no nāʻoihana hana lapaʻau e mālama i nā mea a pau. Ua hoʻomaka kēia e hoʻololi me ka hoʻokomoʻana i ka'OBD-II ,ʻo ia keʻano i hanaʻia e nā mea hana kālaihana ma ka honua holoʻokoʻa, akā, hiki i nāʻoihana'ōnoʻopiʻoʻoihana ke kūʻai i nā makahiki heʻumi tausani.
Kū i luna i kekahi mau makahiki i hala aku nei,ʻo ka mea heluhelu a me ka mea heluhelu e kūʻai pinepine ana i nā haneli haneli. Hiki i nā'ōnaehana maʻalahi ke heluhelu a wehe i nā code, akāʻaʻole lākou iʻae i nā PID i hiki ke kōkua i kaʻikeʻana i nā pilikia a me nā pilikia'ē aʻe.
ʻO ka ELM327 i hoʻolālā i ka microcontroller he mīkiniʻuʻuku, kōkua liʻiliʻi hiki ke kōkua i ke alahaka i kēlā āpau. ʻO nā pūnaewele e hoʻohana ana i kēia microcontroller, e like me ka Yongtek ELM327 Bluetooth scanner ,ʻaʻole lākou e paʻa i ke kukui i nā'ōnaehana'ōnika akamai, akā hāʻawi nui lākou i kaʻike ma ka lima o ka poʻe DIYers.
Peheaʻo ELM327 e hana?
E hana ana ka microcontroller ELM327 ma keʻano he alahaka ma waena o ka computer ma luna o kāu kaʻa a me kāu pakuhi pūnaewele. ELM327 hiki iā ia ke kamaʻilio pū me ka pūnaewele OBDII a laila e kīkēiho ana i nāʻikepili ma o USB, WiFi, a iʻole Bluetooth , e hilinaʻi ana i ka hoʻokomo ponoʻana.
E kākoʻo ana ELM327 i nā kūlana SAE a me ISO maʻamau, a ua hiki i nā polokalamu ELM327 pono ke kamaʻilio me kekahi oBDII. ʻO ka papa kauoha i hoʻohanaʻia e ELM327ʻaʻole ia e like me ka hoʻonohonohoʻana i nā kauoha o Hayes, akā, uaʻano like loa.
He aha kaʻu e hana ai me ELM327?
Hiki iāʻoe ke hoʻohana i kahi polokalamu ELM327 e kōkua i ka hōʻailonaʻana i kāu kaʻa a kāleka paha, akā makemakeʻoe i kahi mea hou a me nā lako polokalamu. Hiki ke hoʻohuiʻia nā pūnaewele ELM327 i nā kamepiula , smartphones, papa, a me nā mea'ē aʻe ma o nāʻano likeʻole. ʻO nāʻano kumuʻekolu o kēiaʻano:
- Nā leka uila USB
- ʻO ka koho nui loa.
- ʻAʻole pili pono no kaʻole o ka leki uila.
- ʻAʻole kūpono o kahi pilina pili.
- Hiki i ke kaula ke komo i ke ala.
- Nā leka uila WiFi
- Hoʻohanaʻia me nā mea'ē aʻe ma mua o Bluetooth.
- Pipiʻi.
- Bluetooth
- Kahi pili ponoʻole.
- Aia ke Bluetooth ma ka nui o nā'ōnaehana.
- ʻIe likeʻole i kekahi mau polokalamu, e like me iPhones.
Inā loaʻa iāʻoe kahi polokalamu PC a iʻole polokalamu Android, e hoʻohana kekahi o ia mau mea. Inā loaʻa iāʻoe kekahi iPhone a iʻole iPad,ʻaʻole pahaʻoe e hoʻohana i kahi polokalamu ELM327 Bluetooth no ka mea e hoʻohana aiʻo iOS i ka paʻakūele Bluetooth. Hiki i nā lako i kālaiʻia ke hana, akāʻo ia ke halihali i kahi kūlana o ka pilikia.
Hiki iā ELM327 ke hāʻawi iāʻoe i ke komo i nā code codes pilikia a hāʻawi pū iāʻoe e nānā i nā PID. Ma muli o kaʻoluʻolu o ka laulaʻana, ELM327 hiki iāʻoe keʻae i ka hōʻaiaʻana o nā code ma hope o kou hoʻopaʻaʻana i kahi pilikia. ʻO nā hana kūikawā āu e hana ai, e hilinaʻi ia ma kāu polokalamu ELM327 pono a me ka polokalamu āu e hoʻohana nei, akā hiki iāʻoe ke nānā i ka nānāʻana i ka mākaukau a me nāʻike'ē aʻe.
E makaʻala no nā Kenelo a me nā Pirates
He nui nā clones a me nā mea pōā i ke kālepa, aʻoi aku kekahi hana ma mua o nā mea'ē aʻe. ʻAʻole i kope kopeʻia ka v1.0 o ka ELM327 microcontroller code copy by Elm Electronics, a ua hopena ia i ka wā e'ānaiʻia ana. Ua hoʻololiʻia kekahi mauʻenehana e hoʻohana ana i kēlā code kahiko i ka hōʻikeʻana e hoʻohana nei lākou i ka mana o kēia manawa, aʻo kekahi poʻe e hōʻike pū i kahi mana hou aku iʻole e koe.
ʻO kekahi mau'elepoki pirated he mea paʻa, aʻo kekahi mau mea nui loa. I kekahi hihia,ʻoiaiʻaʻole nā kolonā paʻa i nā hana hou i loaʻa ma nāʻano hou o ke code ELM327 pono.
Ke nānāʻana i nā mea'ē aʻe i ka ELM 327
Inā makemakeʻoe e hoʻohana i kahi mea hana'ōkuhi standalone, aia nāʻano koho'ē aʻe i hāʻule i loko o nāʻano likeʻole o nā papa kūʻai kūʻai:
- Nā leka heluhelu heluhelu
- ʻO ka hiki ke heluhelu a me nā hoʻopalapala hoʻopau wale nō.
- Nā mea uila i kūkuluʻia
- Hoʻokomo nā pūnaewele kumu i nā wae a me nā PID.
- ʻO nā pae kiʻekiʻe me nāʻike hoʻoponopono.
- Mālamaʻo'OBD-i nā mea hana
- Ponoʻoe inā e kūkuluʻia kāu kaʻa ma mua o 1996.
- ʻO kekahi hana me kahi kaʻa hoʻokahi wale nō.
- ʻO nā mea'ē aʻe e komo i nā mea hoʻololi no ka hoʻohanaʻana me nā kaʻa he nui.
ʻOiai nā'ōpili e hoʻohana ana i ka microcontroller ELM327 i nā huahana iʻoi aku ka maikaʻi loa,ʻo kaʻoi aku o ka maʻalahi no ka nānāʻana i nā code a nānā i nā PID, aia kahi kahi e koho ai kekahi o nā koho i luna. No ka lālā, ELM327 wale nō e hana me'OBD-II, no laila,ʻaʻoleʻoe e maikaʻi iā ELM327 scan ka mea i hanaʻia ma mua o ka makahiki 1996. Ināʻoleʻoe he mechanicʻoihana, e hana maikaʻi ka ELM327 i ka hapanui nā kūlana'ē aʻe.
