Zasnova, razvoj in izdelava testne naprave za preizkušanje vgrajenih sistemov za zajemanje podatkov

JAKOPIN, BLAŽ (author), Bojkovski, Jovan (mentor)

Diplomska naloga opisuje zasnovo, razvoj in izdelavo testne naprave za preizkušanje vgrajenih sistemov za zajemanje podatkov. Naprava bo uporabljena v večjem avtomatiziranem testnem sistemu, ki na eni strani generira referenčne vrednosti s testno napravo, na drugi pa te vrednosti meri z napravo, ki je testirana, in primerja izmerjeno vrednost z referenco, da ugotovi, ali je meritev znotraj toleranc. Z obzirom na tehnične specifikacije in zahteve testnega sistema se lotimo zasnove testne naprave, ki naj bi v prvi vrsti nastopila kot izboljšava že obstoječe rešitve. Zasnova testne naprave obsega analizo že obstoječih rešitev in predlog izboljšave podprt s teoretičnimi predpostavkami in ugotovitvami. Zastavimo koncept celostne rešitve problema testiranja vgradnih sistemov za zajemanje podatkov po principu PXI sistemov, v okviru diplomske naloge pa tudi razvijemo in izgradimo integralni del testnega sistema, modul funkcijskega generatorja.

Abstract

This thesis describes the design, developement and production of a device for testing different embedded data aquisition systems. This device will be a part of a larger automated testing system, that uses generated values as a reference to test a specific data acquisition device and notifies the user when a specific test case falls out of tolerance. With respect to the technical specification and requests from the existing testing system we start with the planning and designing a device that should firstly improve the existing solutions. The design of such a device is composed of analisys of already known solutions and suggestions on how to improve them, supported with theoretical assumptions. First we set up a larger concept of a device that could provide an overall solution for automated testing of embedded data acquisition systems similar to a PXI (PCI eXtensions for Instrumentation) system, but we focus only on a smaller part of this task – the signal generation module.
