Abstract :
In normal we used to control the industrial equipments by manual operation. Hence it is to be updated step by step manually. It is overcome by a new mode of communication which is used to control all those equipments through load sharing mechanism by a single message from anywhere.GSM is the most popular mobile phone system in the world which could be used for this controlling operation from anywhere else
GSM
-global system for mobile communication is used a media which is used to control monitor the transformer load from anywhere by sending a message. It has its own deterministic thereby, here GSM is used to monitor and control the DC motor, Stepper motor, temperature sensor and solid state relay by sending a massage through GSM modem. Hence no need to waste time by manual operation and transportation. Hence it considered as highly efficient communication through the mobile which will be useful in industrial controls, automobile, and appliances which would be controlled from anywhere else. It is also highly economic and less expensive; hence GSM is preferred most for this mode of controlling.
Detailed Description:
The main aim of this project is transformers sharing whenever the load increased for certain value and also sending these changes information to the respective authority via SMS by using GSM modem. The transformer load sharing will be done by micro controller with the help of electro-magnetic relay. And the load will be monitored on LCD with help of current transformers.
The major building blocks of this project are:
Regulated power supply.
Micro controller.
Voltage Transformers.
Current transformer.
LCD driver circuit.
RS-232 interfacing.
GSM modem.
LCD Display.
Electromagnetic Relay.
Reset.
Crystal oscillator
