Abstract

Diplomsko delo opisuje razvoj komunikacijskega vmesnika med vodilom RS-485 in tehnologijo BLE za lažje testiranje električnih števcev podjetja Iskraemeco. Uporaba vmesnika bo omogočala, da je električni števec od računalnika oddaljen dlje, kot bi mu to omogočala dolžina kabla. V prvem poglavju je predstavljen električni števec in vodilo RS-485, v drugem poglavju je opisana komunikacija BLE, RS-485 in protokol HDLC, nato pa je opisana predelava programske predloge za mikrokrmilnik Nordic nRF52832, izbira in impedančna prilagoditev antene za BLE, zasnova ter risanje tiskanega vezja s programom Altium. Na koncu so predstavljeni rezultati in delovanje komunikacijskega vmesnika.

Secondary title: Design and implementation of RS-485 bus and Bluetooth wireless technology communication interface
Secondary abstract: The thesis addresses development of a communication adapter between RS-485 bus and BLE technology for easier testing of electric meter. Communication adapter will allow electric meter to be situated at a distance from the computer greater than the cable length. The first chapter presents the electric meter and RS-485 bus, the second chapter describes the BLE, RS-485 and HDLC protocol. Then follows the description of modifying the firmware template for microcontroller Nordic nRF52832, selection and impedance matching of the antenna for BLE, designing and drawing a printed circuit board with program Altium. Operating results of the communication adapter are presented at the end of the thesis.
