Design And Construction Of A Monthly Electricity Billing Display System
Overview
ABSTRACT
The project provides a system that allows for consumed electricity reading in units as well as the amount charged over it to the user. This system provides the electricity readings on an LCD screen and cost to the user. This lets the user know about his exact electricity units consumed and cost directly from his meter so that there is no chance of bill tampering. The project allows a one way reading – on LCD display. The system continuously monitors electrical pulses and calculates the unit consumption. The system then uses the cost of each unit to calculate the electricity cost. It displays it on an LCD screen for viewing.

1.0 INTRODUCTION
Monthly Electricity Billing Display System using pic microcontroller: Monthly electricity billing display system is a system, that would be given the monthly electricity bill intimation to the customer via LCD and this bill intimation would be before the supply company such as PHCN monthly bill. Nowadays, the PHCN or other supply companies are paying over charge because mostly customers do not have the time to check the meter reading or do not have the information how to the calculate the monthly electricity bill therefore the supply companies are taking the benefits of their negligence. On keeping these issues, we have designed a system that is called a monthly electricity billing display system with the help of PIC microcontroller 18F452, energy meter, LCD display. This system could be installed with customer energy meter and displays the energy meter reading with their consumable units and cost. By using this system, the customers can easily know their energy meter reading, monthly bill at their screen and can save their time and over charging of supply companies.
1.1 BACKGROUND OF THE PROJECT
Electrical power has become indispensable to human survival and progress. Apart from efforts to meet growing demand, automation in the energy distribution is also necessary to enhance people’s life standard. Traditional meter reading by human operator is inefficient to meet the future residential development needs. So there is increased demand for Automatic Meter Reading (AMR) systems which collects meter readings electronically, and its application is expanding over industrial, commercial and utility environment.
Electronic utility meters are an important step towards automating the utility metering process. Automated utility meters have many new features that help to reduce the cost of utilities to customers and the cost of delivering utilities to the utility provider. The onset of rural electrification provides opportunities for new and more efficient metering technologies to be implemented. Traditional electro-mechanical meters, still widely used today, are prone to drift over temperature and time as a result of the analogue and mechanical nature of the components in these meters. Collection of meter readings is also inefficient, because a meter reader has to physically be on site to take the readings. This method of collecting of meter readings becomes more problematic and costly when readings have to be collected from vast, and often scattered rural areas. Meter readers are reluctant to make the effort to travel to such areas and will often submit inaccurate estimations of the amount of electricity consumed. For households at the top of high buildings and luxury housing plots, traditional meter reading is highly inefficient.
There exists chance for missing bills, absence of consumer etc. Even though these conventional meters were replaced with more efficient electronic energy meters these problems still persists. So a system which will provide the bill in users mobile will be more suitable in the current scenario. Here a new method of postpaid electronic energy metering is introduced in this paper which will automatically sense the used energy, records these reading continuously, then display it to the user via LCD screen. As it is web oriented once the data is updated, the registered users and authority can monitor and analyse the generated bill of any month by sitting anywhere in the world.
1.2 PROBLEM STATEMENT
In the last decade, electricity bill is been charged by estimation by power supply companies such as PHCN ( Power Holding Company of Nigeria) , and this led to overcharge on the bill because most customers do not know how the bill is been calculated and do not know how to calculate it and because of this, supply companies are taking the benefits of their ignorance. On keeping these issues, we have designed a system that is called a monthly electricity billing display system with bill SMS features with the help of PIC microcontroller, , energy meter, and LCD display. This system could be installed with customer energy meter and displays the energy meter reading with their consumable units and cost. By using this system, the customers can easily know their energy meter reading, monthly bill at their meter display board, and this saves their time and over charging of supply companies.
1.3 OBJECTIVE OF THE PROJECT
The objective of this work is to design an electronics device that provides the electricity bill readings on an LCD screen.
1.4 APPLICATIONS OF THE PROJECT
This monthly electricity billing display system could be used with domestic and industrial energy meters for displaying monthly bill.
1.5 ADVANTAGES OF THE PROJECT
- By using this system, the customers can easily check their monthly electricity bill and then compare their bills with supply company bills or PHCN and save from over charging.
- This system is more compact, reliable and less costly as compared to other systems.
- This system calculates the monthly electricity bill more precisely as compared to the other systems.
- This system is more efficient and easy to install as compared to the other systems.
1.6 SCOPE OF THE PROJECT
In this proposed system, the consumer will get his energy consumption data on real time basis on a LCD display. A microcontroller of 8051 family is interfaced to the energy meter to get the Watt Hour pulses.
The microcontroller then processes these pulses according the program written in it, to calculate the units consumed and cost involved. Further it gives display via LCD.
1.7 DEFINITION OF TERMS
The following terms were used in this work and their meanings are as below:
- PHCN- Power Holding Company of Nigeria
- AMR – Automatic Meter Reading
- LCD – liquid-crystal display
1.8 METHODOLOGY
To achieve the aim and objectives of this work, the following are the steps involved:
