Uporaba komunikacijskega protokola J1939 v vozilih

ABRAM, ZORAN (author), Vončina, Danijel (mentor)

Namen in cilj te diplomske naloge je raziskati komunikacijske protokole. V prvem delu naloge sem opisal 3 komunikacijske protokole, ki imajo za svojo osnovo CAN bus komunikacijo. Opisal sem CANopen, ki je odprtokodni komunikacijski protokol in je ravno zaradi svoje odprtosti zelo zanimiv za širšo javnost. Drugi je DeviceNet, to je komunikacijski protokol, ki se uporablja v industriji. Zadnji komunikacijski protokol, ki sem ga opisal, je MilCAN, ki se uporablja v vojaški industriji, kar je bil glavni razlog, da sem se odločil tudi za njegovo predstavitev. Najobširnejši je osrednji del naloge, ki podrobno opisuje in razčlenjuje komunikacijski protokol J1939. Podrobneje sem ga opisal s pomočjo arhitekture sporočila, načinov komunikacije, številk skupine parametrov, prenosnih funkcij protokola in na koncu še upravljanja z omrežjem. Vse ugotovitve sem poizkušal podkrepiti s konkretnimi primeri. Osnovo celotne diplomske naloge predstavlja projekt, ki sem ga izvajal. To je bila realizacija komunikacijskega protokola za projekt čolna, zato so tudi vse številke skupine parametrov, SPN-ji, PDU f-ji in PDU s-ji, realni. Zadnja tretjina naloge je realizacija projekta. Najprej je predstavljen pregled demonstracijske plošče, nato pregled strojne in programske opreme ter njihova primerjava in na koncu sledi še realizacija komunikacije.

Abstract

My final thesis is about communication protocols. In first part I described three communication protocols, which are based on CAN bus communication. As first, I described CANopen, that is an open code communication protocol and because of its open access, it’s very interesting for public. Second one is Device net, which is communication protocol used in industry and the third one is MilCAN, used in military industry and this is the main reason why I chosen it as a focus of my thesis. Major part of my thesis is detailed description of communication protocol J1939, which is a higher level communication protocol, based on CAN bus communication. I detailed described J1939 through the architecture of message, ways of communication, numbers of parameter groups, transportation functions of protocol and in the end also network management. As much as possible, I tried to base theoretical description on cases of practical use and on a personal project of realization of this communication protocol for implementation in a boat, so numbers of parameter groups SPN, PDU f and PDU are based on real data. Last part of my thesis is realization. First an overview of demonstration board, followed by an overview of hardware and software and its comparison and in the end realization of communication protocol with its implementation in function is presented.
