Remote energy monitoring, profiling and control through GSM network

This paper presents design and development of a GSM based energy monitoring, profiling and control system. Our system integrates digital energy meters installed at consumer unit with an electric supply company´s energy monitoring system. Single phase or three phase digital electric meter can be used with indigenously developed add on transmission module, which takes the meter reading and utilizes the GSM network to transmit the energy usage reading using Short Message Service (SMS) back to the energy supplier. At the supplier end, an energy monitoring system is used to manage all received meter readings, compute the billing cost, update the database and maintain an energy consumption profile for each user. Various alerts and control can also be generated by the supplier. A simple, cost effective and reliable working prototype of complete system has been developed using digital energy meter manufactured by MicroTech Limited, Pakistan to demonstrate an efficient and transparent means of automatic meter reading, billing and notification through the use of GSM network.
