ELECTRONIC SYSTEM FOR TESTING OF ENCORDERS

V specialističnem delu sta opisana razvoj in delovanje elektronskega sistema za testiranje dajalnikov pozicije. Podal sem več načinov, kako lahko delimo tipe oziroma vrste dajalnikov pozicije, opisal glavne sklope dajalnika in s stališča testiranja poiskal razlike med dajalniki. Tako sem lahko naredil abstrakcijo vseh RLS-dajalnikov oziroma njihovih lastnosti, ki naj bi jih testirni sistem zmogel testirati. Opisani so vsi večji funkcionalni sklopi vezja, ki skupaj omogočajo trimanje in testiranje različnih vrst dajalnkov pozicije podjetja RLS. Vzporedno s testiranjem vezja vmesnika sem razvil program za FPGA na merilnem modulu NI 7841R proizvajalca National Instruments. Na koncu je opisan razvoj postopka umerjanja testirnega sistema. Razvit elektronski sistem se uspešno uporablja kot vmesnik med testirancem in merilnim modulom NI 7841R in je ključni del testnega sistema oziroma naprave za trimanje in testiranje v proizvodnji RLS-dajalnikov pozicije.The thesis describes development and operation of an electronic system for encoder testing. First, different encoder types are described. Then, I describe parts of the encoder system and identify differences between encoders from the testing perspective. In this way, I was able to find abstractions of all RLS encoders and their requirements for testing. Functionality sections of the circuit that enable trimming and testing of RLS encoders are presented. In parallel with circuit testing, the design of FPGA programming for NI7841R DAQ module was in progress. Finally, I describe calibration procedures for the testing system. The developed electronic system is successfully implemented as an interface between device under test and DAQ card NI 7841R. It forms now the key part of testing and trimming system in the production of RLS encoders
