Nadzor in krmiljenje modularnih laserskih sistemov

Kočica, Jernej Jan (author), Petkovšek, Rok (mentor)

V okviru magistrske naloge je bil zasnovan sistem, ki ga nadzorujemo s pomočjo kontrolne enote (FPGA ali mikrokrmilnik) preko SPI protokola. Sistem ima modularno zasnovo, ki omogoča izgradnjo poljubno kompleksnega sklopa s pomočjo krmilnih modulov. En krmilni modul nudi 4 kanale digitalno-analognega pretvornika, 7 kanalov analogno-digitalnega pretvornika ter 7 digitalnih vhodov oziroma izhodov. Z zasnovanim sistemom lahko s pomočjo programskega paketa Matlab krmilimo 96 takšnih modulov, kar omogoča zelo veliko fleksibilnost pri izgradnji laserskih sistemov. Vsi krmilni moduli, ki jih dodamo sistemu, komunicirajo preko enega SPI vodila, zato ob dodajanju novega krmilnega modula v sistem nimamo potrebe po spreminjanju strojne opreme, saj ga le priključimo na SPI vodilo in podamo spremembe v grafični vmesnik.

Abstract

In the context of the master’s thesis, a system was designed which is monitored by a control unit (FPGA or microcontroller) via the SPI protocol. The system has a modular design that enables the construction of an arbitrary complex assembly using control modules. One control module offers 4 channels of digital-to-analog converter, 7 channels of analog-to-digital converter and 7 digital inputs or outputs. With the designed system, 96 such modules can be controlled using the Matlab software package which enables very high flexibility in the construction of laser systems. All the control modules which are added to the system communicate over one SPI bus, so when adding a new control module to the system it is not necessary to change the hardware, because we only connect it to the SPI bus and apply changes to the graphical interface.
