Cilj diplomskega dela je bil načrtati in izdelati matično ploščo za testno napravo, ki bo pohitrila in olajšala testiranje motorskega krmilnika. Namen matične plošče je združiti vse potrebne merilne inštrumente, napajalnike ter signale iz motorskega krmilnika, nato pa preko računalnika RPI izvajati meritve in izdelati poročila teh meritev, ki bodo olajšala nadaljnji razvoj motorskega krmilnika. Glavna naloga matične plošče je avtomatsko preklapljanje faznih signalov za krmiljenje motorja med različnimi motorji, ki jih motorski krmilnik podpira. Pred razvojem te matične plošče so se vse meritve izvajale ročno. To je bilo zelo zamudno, saj je bilo potrebno vse merilne inštrumente in napajalnike nastavljati posamično, prav tako pa tudi ročno preklapljati med različnimi motorji in signali, ki so morali biti povezani z motorskim krmilnikom. Vse te nastavitve in preklope bo sedaj izvajal RPI preko matične plošče. Le ta bo za izvedbo testa potreboval zgolj spisano testno sekvenco, nato pa se bo test izvedel popolnoma avtomatsko. S tem bomo pridobili zelo veliko časa, ki ga bomo lahko preusmerili v nadaljnji razvoj. Matično ploščo v grobem sestavljajo releji, 5 V napajalnik, RPI, STM23 mikrokrmilnik, komunikacijski gonilniki in še nekaj integriranih vezij za obdelavo signalov. The goal of the thesis was to design and develop a motherboard for a test device that will accelerate and facilitate the testing of a motor controller. The purpose of the motherboard is to integrate all measuring instruments, power supplies and signals from the motor controller. Single-board computer RPI is then used to capture all the measurements and to generate a report, which will ease up further development of the motor controller. The main task of the motherboard is to automatically switch phase signals between different motors supported by the motor controller. Prior to the development of this motherboard, all measurements were performed manually. This was very time-consuming, as all the measuring instruments and power supplies had to be individually set up and manual switching between different motors and signals connected to the motor controller was required. All these settings and switches will be now performed by the RPI through the motherboard. It will only require a written test sequence to execute the test completely automatically. This will save a significant amount of time that can be redirected to further development of a motor controller. The motherboard consists of relays, a 5V power supply, an RPI, an STM23 microcontroller, communication drivers and several integrated circuits for signal processing. |
