Utilization of power line for remote control of electrical appliances

Abstract

The goal of this work is studying of the possibilities and properties of the data transfer via power lines. The work deals with remote control of the electrical appliances and problems of data transfer via power line 230 V. The designed devices which provide relative communication via power line are used within the frame of the one family house. Designed devices - concretely input-output unit, PC interface and GSM gate work on a bus principle. The bus is constructed by power line 230 V. Designed devices are composed of microcontrollers AVR and modem TDA5051AT provides their relative communication via power line. Communications protocol with which devices work was developed so that corresponds with hardware resolution of particular devices. Particular devices were practically realized and their activity was checked.
