Design and implementation of a remotely controllable UPS outlet system

Abstract

In this paper we describe a remotely controllable UPS outlet system for home power management that we have developed. Our system can also control the UPS outlet system of different families by means of GPRS technology of a GSM module. The controllable UPS outlet (CUPSO) integrates multiple AC power sockets, a UPS and a low- power microcontroller into a power outlet to switch the power of the sockets On/Off, to protect a sudden loss of the AC power supply and to measure the power consumption of plugged-in electric home appliances. Using Bluetooth, our wireless system can control the home electric appliances without any new wiring. The remote control also provides the user with the ability to turn home appliances on or off by means of the Internet, and the GSM channel linked to the home server is able to receive the necessary SMS (short message service) to turn the home electric appliances on or off anytime and anywhere.
