GSM-Controllable Power Switch System for Industrial Power Management

In this paper we describe the GSM Power-Controlled Outlet System (GPCOS) with a scalable mechanism for industrial power management. The GPCOS integrates the multiple AC power points and a simple low-power microcontroller into a power outlet to switch the power of the sockets ON/OFF and to measure the power consumption of plugged electric industry appliances. Our GPCOS consists of four scalable modules, that is, the Essential Control Module,the GSM Module, the Ethernet Module and the Power Measuring Module, which together provide an outdoor remote control and monitor of electric industrial appliances. We use a Short Message Service to achieve control and monitoring through a GSM cellular mobile phone for remote use anytime and anywhere.
