SPRS: Standby power reduction system for efficient power management

Abstract

As the internet is evolving for the last two decades, home networks that can connect all home appliances are emerging. One important topic in such a network is how to reduce the power consumption of all home appliances, since the appliances consume significant power in total even in standby mode. This paper proposes a system called SPRS (Standby Power Reduction System), which tries to reduce the power consumption by physically turning off appliances in standby mode. It is possible by a centralized power management server plus a sensor device monitoring the power consumption of the associated appliance, connected between a socket outlet and the power cable of the appliance. Through experiments, we show that the proposed system detects whether an appliance connected is in standby mode, and cuts off the power at an appropriate instant in order to save the standby power. © 2011 Authors.
