ABSTRACT

Here a lot of customs are used electrical energy but not pay the bills in time.so here we avoid this problem by using this project. We can measure the power by each load and take the information through the mobile by using GSM module. After the taking alert from the situation the consumer not respond for emergency alert we can cut –off the supply to the consumer by automatically.

Keywords—Liquid Cristal Display, GSM, LCD, PSU

I. INTRODUCTION

If any consumer did not pay the bill, the operation needs to go to their houses to disconnect the power supply. These processes are time consuming and difficult to handle. By the system, cut the supply automatically. The use of Arduino (microcontroller) there are many improvements in automating various industrial aspects for reducing manual efforts. Now a day the number of Electricity consumers is increasing in great extent. It became a hard task in handling and minting the power as per the growing requirements.

etc., A whole new breed of projects can now be built that can be controlled from a computer.

2.1 LCD (Liquid crystal display)

• LCD Pin no 1, 3, 5 & 16 are connected to the

ground.

• LCD Pin number is 2 & 15 are connected to the

VCC (5V DC) supply.

• LCD Pin number 4 &6 are connected to

ARDUNIO Board pin number 2 & 3.

• LCD Pin number 11, 12, 13 & 14 are connected

to ARDUNIO Board pin number 4, 5, 6 & 7.

III. ENERGY METER

• Energy meter is connected to the relay pin

number 1 & Arduino board pin number () connected.

• Energy meter is a main load indicator device.

“A smart meter is an electronic device that records consumption of electrics energy in intervals of an hours or less and communicates that information at least daily back to the utility for monitoring and billing. … Unlike home energy monitors, smart meters can gather data for reporting.”

3.1 Applications

• House Hold Purposes

The Allegro ACS75x family of current sensors provides economical and precise solutions for current sensing in industrial, automotive, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, power supplies, and overcurrent fault protection.

VI. GSM (GLOBAL SYSTEM FOR

MOBILE COMMUNICATIONS)

GSM (Global System for Mobile

communications) is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. GSM networks operate in four different frequency ranges. Most GSM networks operate in the 900 MHz or 1800 MHz bands. Some countries in the Americas use the 850 MHz and 1900 MHz bands because the 900 and 1800 MHz frequency bands were already allocated.

VII. CONCLUSION

This research paper demonstrates the concept sand implementation of automatic trip control system for energy management using Arduino controller and GSM. It mainly focused on industrial purpose. The similar idea can be implemented for domestic areas for avoiding the illegal usage of electricity. This paper is aimed at reducing the heavy power and revenue losses that occur due to power theft by the customers. By this design it can be concluded that power theft can be effectively curbed by detecting where the power theft occurs and informing the authorities. Also, an automatic circuit breaker may be integrated to the unit so as to remotely cut off the power supply to the house or consumer who tries to indulge in power theft.

FUTURESCOPE

Though many have tried implementing a country wide AMRS, it is still an unreachable goal, many factors like cost, feasibility and mainly the need to replace the existing system have hindered its

development. At least in near future, the cost involved in the building of this system could be minimized by using more efficient technology implemented worldwide.
