Possessing own transportation has become
more common nowadays. The number of vehicles on the road keep on increasing and
most of us are eager to own personal vehicle as we can go anywhere without
limitation.
In case we are unable to afford personal
vehicle, public transportation such as bus, train and cab is the most
convenient option for us to get ourselves to another destination from time to
time. In this project, we will concentrate on train only.
Undoubtedly, the existence of train has
reduced road traffic. Besides, it provides a low-cost transportation, which is
a means to the low-income family for traveling to another destination.
Most often, it is desired to travel in
train for long distance & reach the destiny in odd timings especially at
mid nights.
Most often, we will be busy in our own
daily work. So we need someone to remind about destination.
PROJECT
OBJECTIVES:
The
objectives of this project are:
Ø To
create an application that is able to estimate destination station and alert
the passengers through short message service.
Ø To
offer a convenient mobile information service, this ensures the passengers to
get the alert of destination station in the previous station.
Ø Main
objective is to alert the passengers. As the “mobile” is portable thing &
is now the best way of communication.
Ø So
we have chosen the “SMS” as the best service to intimate the people as even the
basic sets will support this facility. Hence better way to alert all class
people and is cost effective.
WHY IT IS
NEEDED?
As we have seen any
country of the matter more than 70% of people relay on public transport it may
be a big metropolitan city or small village with a small community of people.
Most of the people in this metropolitan city or village are the middle class
and low class people they are very much relayed on this public transport to go
to the various destination, as it offer one of the most cheapest mode so all
middle and low lass people relay on this to their daily activity.
There is a possibility that train
passengers travelling over long distance can miss their destination station and
reach unknown city or village especially at mid nights .It can lead to
frustration and disappointment.
So for those people this project could
brings a solution to overcome the above problem. The figure 1.1 shows the
condition of passenger travelling over long distance.
ABOUT THE PROJECT:
Below figure 1.2 shows the implementation block
diagram of “SMS Based Alerting System for Train Passengers”.
The
block diagram consists of Microcontroller Unit ( P89V51RD2), GSM Modem, MAX 232
IC, RS-232 port, 4x3 Key-pad, IR sensors, LCD Display.
The
following steps briefly demonstrate our project.
STEP1:-Passenger
enters the destination station number and phone number using a keypad while
taking ticket and LCD is used for displaying the user information. (Ref. figure
1.3)
STEP2:-Once
the passenger enters the train and starts his journey, the IR sensors situated before
each station senses the arrival of train, and sends the control signal or IR
status signal to Microcontroller Unit (MCU). (Ref.fig 1.4)
STEP3:-The
IR status signal is sent to the microcontroller (particular destination station
number which is predefined) enables the GSM modem to send SMS to the
passenger’s mobile by using serial communication (RS-232 port & MAX-232
IC). Figure 1.5 shows the SMS sent to passenger’s mobile from GSM modem.
ADVANTAGES & DISADVANTAGES:
Advantages:
Ø The
passengers can get arrival time of train.
Ø It
is helpful to identify the destination station very easily.
Ø This
can also be used for buses also.
Disadvantages:
Ø Velocity
of the train will not be same throughout the distance.
Ø Network
congestion.
Ø Reader
fails to read the tag from great distance if there is a rain or fog.
Conclusion:
Avoidance of missing the destination can
now be overcome by implementation of SMS based station alerting system within
the train and station. It uses the combined technology of sensors (sensing for
train arrival), GSM technology (for SMS alerting), programming skills for
interface of various circuits to a chip so called microcontroller. Related
circuits of various components and its interfacing circuit diagrams, related
issues, soft-wares used and related programs as a pictorial representation have
been documented in this book. To overcome issues related to sensors and other
areas theoretical models have been given in appendices. So by implementation of
such system information services remain fundamental to passenger satisfaction;
slight adjustments can be made for real time application using GPS (Global
Positioning System) tracking system.
After studying this report one can able
to build such a model for practical applications with some slight changes. In
this project we have implemented circuit for one-way communication i.e.
alerting the passenger from station site by collecting his/her cellphone number
at the ticket counter. It can also be extended for two-way communication i.e.
by sending the SMS from customer site to the application in the specified
standard format one can get the information related to train such as location
of train, arrival time. So if such application is implemented in real time then
it will be greatly helpful to the public.
One can even extend this application with
inclusion of other functionalities such as automatic announcement (within the
compartments in different languages inside the train), these services over
internet, etc., with expansion of memory and/or using database router for
storage of large customer data. Ideas and implementation of application are
still an open issue so that one can work on it. Different implementation will
come up with blend of different drawbacks, but proper standardization and depth
they cover in efficient and effective manner can lead to best successful
implementation; one such approach has been done in this report.
