A Practical Intelligent Home System Based on Power Line Communication

This paper presents a practical, cost-effective intelligent home system based on power line communication, in which manual keypad control, speech control and GSM/GPRS remote control are implemented. In this system, speech control is for old men and handicapped people who are unable to operate home appliances. A focusing fuzzy template matching algorithm is proposed to improve the accuracy of speech recognition under noisy background. GSM/GPRS remote control makes operation of home appliances and home surveillance feasible anywhere. Because of the implementation of power line communication technology, no rewiring is required, thus making the installation of such system simple, low-cost and efficient, which is favorable for the popularization of intelligent home. An experimental mini intelligent system is presents in the end.
