Coin based mobile charger using Solar tracking system
[attachment=67938]
Abstract:
This paper describes coin based mobile
charger using solar tracking system. Mobile phone’s
become a major source of business/personal
communication; the mobile phone business is
currently worth billions of dollars, and supports
millions of phones. The need to provide a public
charging service is essential. Many critics argued
that a public mobile phone charging service is not a
lucrative business because most users can charge
their phones at home, in their office or in their cars.
Coin operated mobile phone charger is new
business milestone because many are attending
business conventions and forgetting their charger at
home or in hotel rooms. Students and many people
use the public transportation that don’t know that
their level of their battery is low are prospective
customers for coin operated mobile phone charger
service. Recommended locations include: Hotels,
Conference centres, Exhibition halls, Serviced
offices, Exchange halls, Motels, Leisure centres,
Health clubs, Training centres, Golf clubs, Retail
outlets, Shopping malls, Internet cafes, Universities,
Colleges, Hall of residence, Airports, Train
terminals, etc., so that the mobile phone users can
reactivate a low or dead battery by simply plugging
in and charging for one rupee. This is designed
based on ATMEL 89c51 a 40-pin micro controller
that does the countdown timings for a period of 3
minutes with LCD displays showing the actual time
left. During the timing period a relay output is
latched and finishing timing in progress.
. Introduction
Usually ordinary solar panel is always faces
only in one direction. Because of this reason the solar
panel may not get sufficient sun rays to work. In this
work SOLAR PANEL CONTROLLER AND POWER
OPTIMIZATION is done in order to overcome this
defect. Here the panel will rotate according to the
readings read by the LDR. So it will utilize the full sun
light to work & power optimization is also done by using
the LDR.
This work mainly designed to control the solar
panel automatically, maintains face of the solar panel
towards the sun. This is done by controlling the
mechanical movement of the solar panel. Usually sun
rises at east and sets at west. In ordinary system, if it
faces towards east then it cannot change the direction
towards sun during sunset. Because of this reasons
solar panel may not get sufficient sun rays to work.
These problems are overcome by using this
work. In this work we also build a very good micro
controller based solar charger. The coin-based mobile
battery charger developed in this work providing a
unique service to the rural public where grid power is not
available for partial/full daytime and a source of revenue
for site providers. The coin-based mobile battery charger
can be quickly and easily installed outside any business
premises.
The mobile phone [1] market is a vast industry,
and has spread into rural areas as an essential means
of communication. While the urban population use more
sophisticated mobiles with good power batteries lasting
for several days, the rural population buy the pre owned
mobile phones that require charging frequently [2].
Many times battery [3] becomes flat in the
middle of conversation particularly at inconvenient times
when access to a standard charger isn't possible. The
coin-based mobile battery chargers are designed to
solve this problem. The user has to plug the mobile
phone into one of the adapters and insert a coin; the
phone will then be given a micro-pulse for charging. It
does not bring a mobile from 'dead' to fully charged
state.
The charging capacity of the mobile is
designed with the help of pre defined values. It is, of
course, possible to continue charging the mobile by
inserting more coins. This compact and lightweight
product is designed to cater for the growing number of
rural mobile users worldwide. A suitable microcontroller
is programmed for all the controlling applications. The
source for charging is obtained from direct power grid
and solar energy [4] in case of non availability of grid
powe
Controller
This section acts according to the input signal
from the sensor circuit. Coin accepted or rejected is
based on the diameter of the coin. This invokes
microcontroller along with LCD interface displays the
selection of mobile option if particular mobile is selected
for charging the corresponding routine is activated and
charge the mobile for a particular duration of time .When
the routine completes, it indicates charge complete
message through LCD display. Similarly the same
procedure is followed for charging more than four
different mobiles simultaneously [1] .The simple routine
is indicated through flowchart as shown in the Fig 4.
3.3.3 Output and Display
The LCD displays all the information to the
customer as and when required. When the mobile
battery is connected, it displays” Insert Coin”. While
charging it displays “Charging” and at the end of
charging cycle it displays “Charge completed”. For
charging continuously the coin has to be inserted when
the display shows “Charge Completed” The output has
10 terminals for connecting different types of mobile
batteries [7] and 7 of them are internally connected for
charging mobile batteries of different make as shown in
Table 1 [1] below:
Conclusions
In this work a novel method of charging mobile
batteries of different manufacturer using solar power has
been designed for rural and remote areas where the
current supply is not at all available all the time. This
paper is very useful in today’s life. Because now days
the necessity of communication is very important, so
every person having cell phone but every time we
cannot carry charger with us. When we are going for
long travel we may forget to carry cell phone charger.
