Due to the drastic changes in technology in the last decade, so many advancements were introduced in electricity departments. The present system is like, a person from electricity department has to go to each and every house to take the readings from the digital meter and present these details to the billing department and after all their processing, they generate a bill and another person comes and gives the electricity bill to us and finally we have pay the bill.
To eliminate this long process and to make the work easy and also make the system totally an automated one, we have designed this project. Since the meter that reads the number of consumed units is actually a digital meter, it contains a controlling unit in it. To this unit, a GSM modem will be interfaced.
The modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. The GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
This system containing the energy meter calculates the power consumed by the house and sends the total number of units consumed and the amount to be paid for the consumed units, for a month, to the electricity department and also to the user. The user has to pay the bill within the due date. If the user did not pay the amount within the due date, the electricity department sends a predefined message to the system containing the energy meter. Thus, this system shuts down completely and the user cannot use the power from the energy meter until he clears the bill amount.
