Development of a device for testing communication and power supply between the electric meter and communication module

V procesu razvoja novih naprav je ključno hitro in enostavno testiranje njihovih sklopov. V podjetju Iskraemeco, d.d., se je pojavila potreba po namenski napravi za lažje testiranje komunikacije med električnim števcem in njegovim komunikacijskim modulom. V magistrskem delu je opisan razvoj takšne naprave od načrtovanja do preizkušanja. Napravo je mogoče krmiliti preko mikroračunalnika Raspberry Pi ali osebnega računalnika. Preko naprave je možno spremljanje in spreminjanje komunikacije UART, spremljanje vrednosti napetosti in tokov, nastavljanje in spremljanje kontrolnih signalov ter programiranje električnega števca. V magistrskem delu je opisana tudi programska koda v programskih jezikih Python in C, ki je bila uporabljena za testiranje naprave.In the process of developing new devices, it is crucial to quickly and easily test their assemblies. In the company Iskraemeco, d.d., there was a need for a dedicated device, to facilitate testing of communication between the electric meter and its communication module. The master’s thesis describes the development of such a device from design to testing. The device can be controlled by a Raspberry Pi microcomputer or a personal computer. Via the device it is possible to monitor and modify the UART communication, monitor voltage and current values, control and monitor control signals and program the electric meter. The master’s thesis also describes the program code in the Python and C programming languages, that was used to test the device
