Abstract: [slo] [eng]
V tejto diplomovej práci je rozobraný návrh a taktiež implementácia na softvérovej a hardvérovej úrovni zariadenia, ktoré slúži na komunikáciu a získavanie diagnostických dát z riadiacej jednotky automobilu. Získané dáta môžu byť uložené na strane zariadenia a taktiež odoslané prostredníctvom technológie LoRa a siete TheThingsNetwork do databázy na vzdialenom serveri. Pre dáta, ktoré je potrebné získať v reálnom čase je použitá technológia NB-IoT. Zaznamenané údaje sú prezentované formou mobilnej aplikácie, ktorá užívateľovi zobrazuje získané dáta a môže ho upozorniť na vzniknutý problém na vozidle. Zariadenie komunikuje s automobilom cez zbernicu CAN s použitím protokolu OBD2 a je ovládané ARM mikrokontrolérom. This diploma thesis deals with the design and implementation at the software and hardware level of the device, which is used for communication and acquisition of diagnostic data from the car control unit. The acquired data can be stored on the device and also sent via LoRa technology and TheThingsNetwork to a database on a remote server. NB-IoT technology is used for data that needs to be obtained in real time. The recorded data is presented in the form of a mobile application, which displays the obtained data to the user and can notify him of a problem with the vehicle. The device communicates with the car via the CAN bus using the OBD2 protocol and is controlled by an ARM microcontroller.
