X10 PROTOCOL BASED POWER-LINE AUDIO COMMUNICATION AND AUTOMATION SYSTEM

Abstract

This paper serves as a general and technical reference to transmission of audio using a power line carrier
communication system which is a preferred choice over wireless or other home networking technologies due to the ease
of installation, availability of AC outlets, higher throughput, low cost, reliability and security. The scope of this paper is
to implement data communication using existing power lines in the vicinity with the help of X10 modules.
Here in this project wired type of communication is used. But transmission is done on existing electrical line of 230
volts. This paper is about power-line voice communication over the low-voltage network. Power-line communications is
the use of in-house power supply network for communication perseverance. Power-line network has very widespread
arrangement in every building and power-line is developed for transmission of power at 50-60 Hz and 230 volts. Hence
use of power-line network for transmission of voice with power supply has increased considerations. The communication
approach that eventually could be used for voice transfer over the power-line network is described. Power transmission
is achieved by using the principle of superimposition of voice over power in power-line cables. The structure described
can be improved and reformed for future requirements.
In this paper DTMF decoder and encoder as well as micro controller in this project to pursue AUTOMATION. X10
protocol is used for communicating in between transmitting and receiving modem
