Nov peb qhia txoj hauv kev yooj yim kom tau txais cov ntaub ntawv los ntawm OBD-II txuas ntawm koj lub tsheb, nrog rau GPS cov ntaub ntawv. OBD-II, Qhov Kev Tshawb Fawb Ntawm On-Board Thib Ob, yog lub sijhawm tsheb hais txog lub tsheb tus kheej kuaj mob thiab tshaj tawm peev xwm. Cov kab ke OBD muab rau tus tswv tsheb lossis tus kws kho tsheb nkag mus rau qhov xwm txheej ntawm ntau lub tsheb sib txuas.

Kauj Ruam 1: Peb Xav Tau Dab Tsi

Peb xav tau, 1. OBD-II CAN Bus GPS Development kit los ntawm Longan-Labs.

2. Ib daim npav micro SD

Cov khoom siv txhim kho tso cai rau koj nkag mus rau koj lub tsheb CAN npav ntawm OBD-II txuas. Cov khoom siv txhim kho tuaj yeem txuas nrog (ntsaws) rau koj lub tsheb OBD-II chaw nres nkoj (On-Board Diagnostics chaw nres nkoj). Lub hauv paus tswj hwm ntawm cov khoom siv txhim kho tau koom ua ke nrog Atmega32U4 microprocessor. CAN-Bus lub tsev qiv ntawv muaj nyob rau sau cov duab kos siv Arduino IDE xa thiab tau txais cov lus los ntawm CAN npav npav network thiab tseem tso cai rau koj mus nqa cov ntaub ntawv muaj txiaj ntsig los ntawm cov lus. Cov ntaub ntawv tso tawm tuaj yeem nqa los ntawm USB Hom-C chaw nres nkoj lossis koj tuaj yeem khaws lawv rau hauv daim npav micro-SD (daim npav TF) los ntawm kev ntxig rau hauv microSD qhov. Lub rooj tsavxwm tseem ceeb hauv cov khoom siv yog ua raws MCP2551 CAN transceiver thiab MCP2515 CAN tus txais, uas muab tus nqi baud los ntawm 5kb/s txog 1Mb/s. NEO-6 GPS kev tawm tsam tau zaum ntawm lub hauv paus pawg thawj coj tso cai rau koj taug qab koj lub tsheb nrog cov qauv me me zoo no los ntawm kev nkag mus hauv GPS cov ntaub ntawv mus rau daim npav microSD.

Kauj ruam 2: Software

Ob peb kauj ruam ua raws:

1. Rub tawm daim duab kos los ntawm Github, uas suav nrog cov lej ua lej thiab cov tsev qiv ntawv.

2. Koj xav tau Typy-C usb cable rau txuas lub rooj tsavxwm rau lub PC.

3. Qhib koj li Arduino IDE, thiab xa cov duab kos rau lub rooj tsavxwm. Xav paub ntau ntxiv.

Kauj Ruam 3: Ntxig Tus Ntaus rau Koj Lub Tsheb

Ntxig daim npav micro SD rau lub rooj tsavxwm, tom qab ntawd koj tuaj yeem tso lub rooj tsavxwm rau OBD-II txuas ntawm koj lub tsheb.

OBD-II interface feem ntau hauv qab lub kauj, koj yuav tsis nco nws.

Kauj Ruam 4: Saib Qhov tshwm sim

Koj yuav tau txais 2 daim ntawv rau txhua qhov kev mus, ib daim ntawv.csv thiab.kml ntawv.

Koj tuaj yeem qhib csv yuav nrog MS Excel, kom tau txais nrawm, rpm ntxiv rau qee qhov lwm cov ntaub ntawv.

KML cov ntaub ntawv yog GPS cav, koj tuaj yeem qhib nws nrog Google Ntiaj Teb.

Txaus siab rau koj hacking!
