Mayelana nalolu hlelo lokusebenza

Inguqulo 1.3.0
I-J1939 Code Reader
Okweselula ye-Android nethebulethi

Imfuneko:
1. Imoto kufanele ihambisane ne-J1939 CAN ukuze usebenzise uhlelo lokusebenza
2. I-adaptha ye-Bluetooth ELM327 noma ehambisanayo
3. Amaloli amaningi enyakatho neMelika asebenzisa isixhumi esingu-9-pins Deutsch, ngakho adinga i-adaptha yekhebula (OBDII Female 16 pins to SAE J1939 Deutsch 9 pins). Amanye amaloli afana namaloli e-Volvo noma amaloli e-Mack (Okwango-2013 nakamuva) asebenzisa isixhumi esivamile se-OBDII J1962 16-pins ukuze angadingi ikhebula le-adaptha.
4. Idivayisi ye-bluetooth ocingweni(I-Tablet) kufanele ivulwe futhi ibhanqwe ne-adaptha ye-bluetooth ELM327 (i-adaptha ye-ELM327)
5. I-Android OS kusukela kunguqulo 4.03 noma entsha

Lesi yisixazululo esingabizi kakhulu. Nge-adaptha ye-Bluetooth ELM327 eshibhile kanye nekhebuli ye-adaptha (OBDII 16 Pins to J1939 9 Pins Deutsch) usuvele unezingxenyekazi zekhompuyutha eziphelele zokwenza uxhumano phakathi kwedivayisi yakho ye-Android kanye nembobo yesixhumanisi sedatha Yemoto. Lawa ma-hardware angatholakala ku-inthanethi kumasayithi e-Amazon, eBay noma kwenye indawo.

Izici:
* Iphrothokholi yokuxhumana ye-OBDII: SAE J1939 CAN 29bit/250kb
* Ifunda/Isula amakhodi amaphutha asebenzayo (noma ayesebenza ngaphambilini) (DTCs)
* Ibuka idatha ebukhoma yenzwa yenjini
* Ishutha ukusakazwa kwebhasi bukhoma kwe-CAN futhi yenze isifinyezo sokusakaza. Ngemva kokwenziwa kwesifinyezo umugqa ngamunye wedatha (uhlaka) kusifinyezo singabhekwa ngokuchofoza kumugqa wedatha.
* Umsebenzi Wokubheka we-PGN/SPN: Isebenzisa imininingo egciniwe ye-SQLite enenombolo engaphezu kuka-3000 ama-SAE PGN ajwayelekile (Inombolo Yeqembu Lepharamitha) kanye nama-SPN (Inombolo Yepharamitha Yokusolwa)
* Igcina idatha yekhodi yephutha yokugcina ukuze isetshenziswe kamuva (Buka)
* Iyunithi Yesikali : Isekela Amayunithi Amayunithi Ama-4 - I-Metric, i-USA, i-Imperial, i-Latin America.
* Isekela amaloli ekilasi 5-8 akhiqizwa kusukela ngo-2004

Isetshenziswa kanjani:
Uma usune-adaptha ye-bluetooth ELM327 exhunywe embobeni yesixhumanisi sedatha yemoto ngekhebula le-adaptha futhi inkinobho yokushisa ivuliwe, ungakwazi ukuxhuma kukhompyutha yesistimu yemoto ngokudonsa phansi imenyu yenketho bese ukhetha into ethi "Xhuma ku-adaptha ye-ELM327", iwindi lengxoxo lizovela futhi libonise uhlu lwamadivayisi abhanqiwe (idivayisi eyodwa noma ngaphezulu ohlwini), idivayisi ngayinye ebhanqiwe inemininingwane emibili:
Igama ledivayisi ye-bluetooth ebhanqiwe (isibonelo: obdII)
Ikheli eliphezulu (isibonelo: 77:A6:43:E4:67:F2)
Ikheli Eliphezulu lisetshenziselwa ukuhlukanisa ama-adaptha e-bluetooth amabili noma ngaphezulu anegama elifanayo.
Kufanele ukhethe idivayisi yakho yebluetooth ELM327 ngokukhetha igama layo elilungile (noma ikheli eliyisilinganiso esiphezulu) ohlwini bese uchofoza entweni, bese uhlelo lokusebenza luqala inqubo yokuxhuma ngaphansi kwephrothokholi ye-J1939.

Uma inqubo iqedwe ngempumelelo, isaziso esithi "Ixhunywe ku-adaptha (ELM327)" sizovela kubha yesimo.

Uma inqubo yehlulekile ungayizama izikhathi ezithile (sicabanga ukuthi i-adaptha ye-bluetooth OBD-II isebenza kahle)

Uma usebenzisa kuphela umsebenzi wokubheka awudingi isinyathelo sokuxhuma esingenhla

Manje usulungele ukusebenzisa yonke imisebenzi yohlelo lokusebenza njengokufunda amakhodi anephutha noma Ukuwasula uma kunesidingo, bheka ama-PGN noma ukubuka idatha ebukhoma yenjini ...

Qaphela:
I-One Fault Code ku-J1939 standard yakhiwe izinkambu ezine (4) ezizimele kanje:
Incazelo Yenkundla, Isifinyezo, Ububanzi Benkambu (Amabhithi), Ibanga
1.Inombolo yepharamitha yomsolwa (SPN) 19 (0-524288)
2.Isihlonzi semodi yokwehluleka i-FMI 5 (0-31)
3.Isibalo Sezehlakalo OC 7 (0-127)
4.SPN Indlela Yokuguqula CM 1 (0-1)

Ibala amanani e-SPN =

(idatha[3]*16777216.0 + idatha[2]*65536.0 + idatha[1]*256.0 + idatha[0]*1.0)*isikali + i-offset

Kuphi
idatha[0] ...idatha[3] iyidatha yamabhayithi angu-4 ye-SPN ebuyisiwe
usebenzisa le datha futhi uqondise ekubhekeni ukuze unqume izingxenye zokubala ze-SPN ezifana:
- ubude bedatha (in bit)
- qala isikhundla se-byte
- qala kancane 1 (ku-start byte)
- qala kancane 2 (ekugcineni byte)
- isikali
- offset
- iyunithi yokulinganisa
