Advantages of UPS Battery Monitoring over GSM

Conclusion

What is UPS?

An uninterruptible power supply(UPS).UPS is an

electrical apparatus that provides battery backup when the

electrical power fails or drops to an unacceptable voltage

level.

Cause of Choosing UPS battery

monitoring over GSM

The system provides detailed UPS running & battery

Voltage information from long distance & Wide Area.

Automatically and continuously monitor data on a 24-hour

basis.

This system is easily maintained and low cost.

Objective

To design a mechanism involving GSM technology to

monitor UPS batteries through sending SMS to mobile

phone in case failure or when battery charge falls to

unexpected level.

System

Operation

When UPS Running from Mains Power

When Mains Power out & Is there Battery1 Voltage >10.5V

Then the GSM Module sends SMS:

UPS Standby, Mains ON,

Charging on;

Battery 1 : 10.5<14.5 V

Battery2 : 10.5<14.5 V

Then the GSM Module sends SMS:

UPS Running from

Battery 1, LVD: 10.5 V

Battery 1 : >10.5 V

Battery2 : >10.5 V

Operation When Battery1 Voltage <10.5

V & Battery2 Voltage >10.5 V When Battery1 & Battery2

Voltage <10.5 V

Then the GSM Module sends SMS:

UPS Running from

Battery2, LVD: 10.5 V

Battery1 : <10.5 V

Battery2 : >10.5 V

Then the GSM Module sends SMS:

UPS Shutdown due to low Battery;

Battery1 : <10.5 V

Battery2 : <10.5 V

Materials of UPS Battery

Monitoring System over GSM

UPS (With 2 Battery)Microcontroller (PIC16F73)GSM Module (SIM908)Relay (12volts dc)Voltage Regulator (LM7805)DiodeResistorCapacitorLEDMicro Switch

Microcontroller (PIC16F73)A Microcontroller is a compact microcomputer designed to

the operation of embedded systems.

Microcontroller is a computer chip. It is able toprogramming though controlling, sequencing, monitoringin low-cost.

GSM Module (SIM908)GSM is the world standard technology for Mobile

Communication.

A GSM module is a wireless module that works with a GSMwireless network.

Since there are many networks provider in our country. Sothat, no need to provide the network. As a result the costwill be reduced in our project.

Relay

A relay is an electrically operated switch. It is operate theelectromagnet system. When Current flowing through thecoil then the relay creates a magnetic field which attracts alever and changes the switch contacts.

Fig. Relay

Voltage Regulator (LM7805) It is a integrated Circuit. It maintains the output voltage at a

constant value.

Diode Resistor

A diode is a specializedelectronic component with twoelectrodes called the anode andthe cathode.

A resistor is a passive two-terminal electrical componentthat implements electricalresistance as a circuit element.

Capacitors LED

A capacitor (originally known as acondenser) is a passive two-terminal electrical componentused to store energy electrostatically in an electric field

A light-emitting diode (LED) is asemiconductor light source.LEDs are used as indicatorlamps in many devices, and areincreasingly used for lighting.

Advantages of UPS Battery

Monitoring over GSMHigh speed of operation.

Remote Surveillance Systems.

Cost effective for monitoring over GSM system.

Automatically and continuously monitor data on a 24-hour basis.

SMS technology is easy to use and can be accessed easily when needed.

Conclusion

GSM based UPS battery monitoring system is beneficial forthe human generation, because nowadays mobile technologyis used effectively & enormously. The system can supervisethe running status of UPS device.
