ELECTRICAL POWER MANAGEMENT SYSTEM IN DOMESTIC APPLICATION BASED ON 802.15.4 COMMUNICATION AND IR CONTROLS

Abstract: This paper describes more efficient domestic energy management system to reduce power consumption in domestic area. We consider the room easily controllable with an IR remote control of a domestic device. The room has automatic standby power switch-off outlets, a light source, and a 802.15.4 hub. The 802.15.4 hub had an IR code learning function and educates the IR remote control signal of a domestic device connected to the power outlet. While the power outlets and the light in the room can be controlled with an IR remote control. This type of automatic standby power cut-off outlet has a waiting time before cutting off the electric power. It consumes standby power during that period of time. To eliminate the waiting time, we turn off the domestic device and the power outlet simultaneously with an IR remote control through the 802.15.4 hub. This method reduces the standby power. The proposed HEMS provide easy way of addition, delete, and move domestic devices to other power outlets. When a domestic device is moved to the different outlet, the energy information of the domestic device is kept consistently and seamlessly regardless of location change. The proposed design structure gives more efficient energy-saving HEMS.
