ABSTRACT
The idea of this smart power system RFID based laptop and
mobile charger using solar panel helps us in the emergency
posture by the way of charging our mobile. In this generation
and the future generation the laptop and mobile are playing
very important role in our day to day life. Due to continuous
work load we face low battery problems and at time
emergency we can’t find any solution at rural place, colleges,
road side, hospitals etc. to deal with this disappointment we
found solution for laptop and mobile charging by suddenly
plugging charger of laptop or mobile after scanning RFID.
When there is no grid power then by using solar energy we
charge laptop and mobile.
Keyword:
RFID, microcontroller, GSM,Sensors
1. INTRODUCTION In many developing countries, the Grid power supply is not
available for several hours on daily basis. Specially in Semi
Urban & rural areas where the laptop and cell phones are
essential communication device. So we use solar panel to
charge battery with pic-controller, RFID, charging circuit and
different laptop charging sockets and cellphone charging
chord. Innovations in laptops and batteries have seen
situations in which the battery can provide up to 24 hours of
continued operation, assuming average power consumption
levels. solar panels are able to generate enough solar power
for the laptop and cellphone to operate. The solar power
application to battery charging has been studied in the past.
Solar chargers convert light energy into DC current for a
range of voltage that can be used for charging the battery.
They are generally portable but can also be firmly mounted.
Also we are using ac supply which is easily available. There
will be condition like that if no any availability of ac supply or
solar light then it use power from battery for charging
purpose.
This project is specially design for laptop and cellphone
charging at emergency situation. It is smart power system
based project because in this project we are using solar energy
and ac supply. Also monitoring current through socket by
using CT. By this no one can use extension box at time of
laptop charging. Using GSM model , at time of fault condition
or misbehavior of system then send message to owner. Tilt
sensor and IR sensor are used for sensing the position of
model means it reduce chance of stolen device. We are
providing three charging circuit. Each one use one slave
controller. There one master and three slave controller.

2. WORKING
2.1 Explanation of master unit: First stage is initialize device and then read tilt sensor which
can measure the tilting in often two axes of a reference plane
in two axes. In contrast ,full motion would use at least thee
axes and often additional sensors. if Tilt sensor is ocher
directly go to socket otherwise send sms to owner through
gsm. Then read IR sensor , In this project IR sensors are used
for detect position of device. i.e to detect that device is present
on its original place or not. Here two sensors that is
transmitter and receiver are used that it will detect the
position of device ,if it misplaced and any person trying to
stole or misbalancing. If this condition false then send sms to
owner and if true then goto battery. To provide power supply
regularly, we use Solar Panel, DC Power Supply, Battery.
Solar panels are devices that convert light into electricity.
They are called "solar" panels because the most powerful
source of light available is the sun. A solar panel is a
packaged, connected assembly of photovoltaic cells. Solar
Panel provide DC power supply which is given to charge the
rechargeable battery of 12V and DC power supply which is
from Grid supply provides DC 12V to charge the battery.
Means here we use two standby power supply. If this
condition false then change battery with AC mains and if true
read RFID tag. If AC main also not available then send sms
to owner. After reading RFID tag it check slot. Then start
charger unit i.e. slave unit. Check AC main. If this condition
false then start inverter. Then go to slave unit.
2.2 Explanation of slave unit:
In this stage slave read data from master unit. Initialize data.
If condition true then after reading RFID tag it decides laptop
charging or mobile charging. For mobile charging current
only flow through charging port and for laptop charging
current flow through socket. After this start timer and read
current. Decrease time and read current. After completion of
time stop charging. At time of charging of laptop chances of
use of extension board to avoid this CT provided. If
overcurrent situation occur then CT measure current if current
more than 5 amp then break circuit.
3. ADVANTAGE: Cellphone charging..
Anti theft system .
Energy efficient system.
Low source indication.
Smart power system.
Less expensive.
More efficient.
Emergency Laptop charging.

4. APPLICATION Industrial applications.
Smart power management system.
Solar systems.
Used at rural area.
5. FUTURE SCOPE No of units can be increased.
Also used theft proof coin based and RFID
based charging system.
6. CONCLUSION This paper improves disadvantages previous RFID based
charger system. There is emergency charging for laptop and
mobile with fault and position detection technique provided
with energy efficiency. It send message for all type of
misbehavior of device to owner.
ACKNOWLEDGEMENT We take this opportunity to express my profound gratitude
