Vgrajen sistem za avtomobilsko diagnostiko z vmesnikom Bluetooth : diplomsko delo

Vurušič, Robert (author), Bulić, Patricio (mentor)

V avtomobilski industriji se uporablja diagnostika OBDII (On Board Diagnostics II) na osnovi vodila CAN (Controller Area Network) za spremljanje stanja vozila. Elektronski sistemi v vozilu so povezani v omrežje, nanj pa se lahko poveže tudi zunanji uporabnik in spremlja celoten promet na omrežju ali pa poizveduje le po določenih vrednostih. Tako lahko pridobi podatke, kot so hitrost ali temperatura hladilne tekočine, lahko pa pridobi tudi podatke o napakah ali nepravilnem delovanju sistema. V diplomski nalogi smo želeli sestaviti sistem na podlagi mikrokrmilnika STM32F407, ki najprej posreduje podatke z vodila CAN preko žične povezave mikrokrmilniku. Nato pa te podatke brezžično posreduje na napravo z operacijskim sistemom Android. Na napravi Android se podatki osvežujejo in prikažejo v uporabniku prijazni obliki. Potrebno je bilo povezati vodilo CAN, mikrokrmilnik, povezavo Bluetooth in aplikacijo za Android.

Abstract

In the automotive industry, the OBDII (On Board Diagnostics II) diagnostics based on CAN (Controller Area Network) bus is used for monitoring the condition of the vehicle. Electronic systems in the vehicle are connected to a network. Outside user can to this network and monitor the entire traffic on the network or inquires only certain values. You can obtain information such as speed or coolant temperature, but you can also obtain information about the error or malfunction of the system. In our thesis we want to assemble a system based on microcontroller STM32F407 Discovery, which collects data from CAN bus and transmits via wired connection to microcontroller. Then this data are wirelessly transmited to Android device. On the Android device the data are periodically refreshed and displayed in user-friendly form. It was necessary to connect the CAN bus, microcontroller, Bluetooth connection and application for Android.
