Introduction

Here we will be using a Mobile as a media, which serves main part of this system. By using home phone as a local phone and another phone - either landline or mobile phone as a remote phone we are controlling power grids.

Also it can be used from any distance from meters to thousand kilometers for interconnection of grids.

Features

› No limit of distance.› Password protection.› Device number display.› Programming in C Language.› Each device has a unique code.› It uses 8051 programmable IC which can be

reprogrammed 1000 times to fit user need.› There is no risk for false switching.› We can control up to 8 electrical connections.› We can control devices from landline or mobile.

 

Component Used 8051 Microcontroller DTMF Decoder HT 9170 Current Amplifier ULN 2803 Positive Voltage Regulator ( 7805 ) 7 segments LED for device number AC cable / protector Transformer Printed circuit board Electrolytic and Ceramic capacitor EEPROM Relay Light Emitting Diode (LED ) Transistors Tactile switch

Project working

1.This project is designed for eight power grids.

2.8051 Microcontroller is the heart of the project.

3.A GSM modem is interfaced to

microcontroller.

Continued.…4.This modem receives the messages

from control mobile and sends as input to microcontroller.

5.The microcontroller verify for authentication of the number and, if the number is authorized, grid control will be taken place.

Continued….6.And EEPROM is interfaced to this

controller to save the grid position at every instant.

7.This grid position information will not be deleted even in power failure conditions.

8.  The device selected code is displayed in seven segment display.

Continued….9. GSM network operators have roaming

facilities, user can often continue to use there mobile phones when they travel to other countries etc….

10.This project uses regulated 5v power supply.

Continued….11. This is achieved by using a 230V to

12V transformer, Bridge rectifier, capacitor filter and 5V regulated power supply from a voltage regulated IC 7805.

12.This 5V source is connected to all ICs and relays.

Advantages System can be monitored and

controlled from any where.

Mobile number can be changed at any time.

Grid status will not be lost in power failure condition.

Scopes for Advancements This system is developed for mobile

reporting application . It also can be interfaced to computer system to record and process data base.

Applications: Process Industries, Power Grids etc.

Conclusion Hence by this project we can control

power grid using wireless communication system i.e., Global system for mobile communications modem.
