Remote control of electrical appliances via power line 230V

Abstract

The submitted work deals with problems of data transfer via power line 230 V for purposes of remote control electrical appliances. In this work were designed devices which provide relative communication via power line 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 up.
