System for CAN bus analysis

CAN protokol vrlo je robustan protokol s visokom pouzdanošću. U radu je teorijski obrađen podatkovni i fizički sloj CAN protokola. Također je izrađen analizator CAN sabirnice. Osmišljen je protokol na višoj razini za testiranje sustava, napravljena mjerenja na podatkovnom i fizičkom sloju CAN sabirnice i opisan postupak i rezultati. Za fizički sloj opisan je postupak mjerenja diferencijalnih smetnji, provjera ispravnosti zaključenja sabirnice i detekcija poretka čvorova na sabirnici. Za podatkovni sloj opisan je postupak mjerenja popunjenosti sabirnice, mjerenje i raspoznavanje grešaka i distribucija grešaka po čvorovima.CAN protocol is a very robust protocol with high reliability. This thesis deals with the theoretical background of data and physical layers of CAN protocol. Additionally, an analyzer of CAN bus was made. A protocol on a higher level for system testing was developed, measurements of data and physical layers of CAN bus were made and the accompanying procedure and results are explained. Regarding the physical layer, the following is described: the procedure of measuring differential noise, checking of validity of bus termination and detection of node order. Moreover, regarding the data layer, the following is described: the procedure of measuring bus availability, measuring and recognizing errors and the distribution of errors per node
