The main aim of the project is to provide back up power supply to corporate, when main supply is not working
The purpose of this project is to provide a secondary power supply, when main power supply is not there, so that services of that corporate should not stopped.. .
In this project , we are using two transformers. One is as mains supply to corporate and second transformer as secondary (UPS) supply. In the beginning we are giving the main supply by transformer one ,but if due to some reason mains supply is not working.
Then by power detector circuit this information goes to microcontroller and buzzer will produce an alarming sound. Microcontroller will send the message to authorized person by GSM modem.
If person wants to continue the power supply by second transformer then that person has to send message to gsm modem. Whenever the gsm modem receives sms message to change the power supply connection it gives instruction to microcontroller .
The microcontroller simply connects the second power supply and disconnects the existing supply using relay based control circuit
GSM (Global System for Mobile communications) is the technology that underpins most of the world's mobile phone networks. The GSM platform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation.
GSM has become the world's fastest growing communications technology of all time and the leading global mobile standard, spanning 218 countries.
GSM is an open, digital cellular technology used for transmitting mobile voice and data services. GSM operates in the 900MHz and 1.8GHz bands GSM supports data transfer speeds of up to 9.6 kbps, allowing the transmission of basic data services such as SMS
With this project we can avoid the disturbance due to main supply. If main supply is absent so we can use the other power supply, by giving the response to microcontroller.
