Sistem za nadzor dostopa

MILIČ, BORUT (author), Bulić, Patricio (mentor)

V diplomskem delu je predstavljen sistem kontrole dostopa, sestavljen iz mikrokrmilnika STM32F4, ki temelji na procesorju ARM Cortex-M4, ekrana na dotik, čitalca pasivnih kartic in pretvornega modula RS232/TCP. Poleg omenjene strojne opreme sta del sistema še dva programa, ki se ne izvajata na mikrokrmilniku. Prvi je strežniški program, ki v bazi uporabnikov preverja vrednosti značk kartic in pripadajočih PIN-ov, drugi pa je namenjen pregledu ter beleženju dostopov, lahko pa tudi dodajamo ali brišemo uporabnike. Na mikrokrmilniku teče FreeRTOS, prosta različica operacijskega sistema v realnem času. Kodiranje krmilnika je izvedeno v programskem jeziku C, drugo pa v programskem jeziku Java in C#.

Abstract

This diploma paper introduces development and implementation of access control system. It is made of STM32F4 microcontroller based on ARM Cortex-M4 processor, TFT touch screen, RFID card reader and RS232/TCP converter module. Part of the system are also two programms which are running outside of the controller. First, the server side program is used to check RFID tags and belonging PINs, the second one does the logging. Beside logging, its functionality is also adding or removing users from the database. Operating system we are using on microcontroller is FreeRTOS, one of the free versions of real time operating systems. We used programming language C for coding the microcontroller and programming language Java in combination with C# for the rest.
