INTRODUCTION Railway is Indias largest transportation medium.

It is the back bone of the country.

It facilitates in travelling large amount of people travel daily fromplace to place.

It is the cheapest medium which is affordable to every class ofsociety.


4/31

INTRODUCTION (CONTD..) But in this project we have designed a train which is controlled by

microcontroller and prevents accidents.

A prospective contraption of 89c52 micro controller controls and can

efficiently do the work without any mistakes.

WORKING PRINCIPLE

When the IR receiver receives the signal from IR transmitter.

microcontroller switches off the dc motor and stops

the train.

And first announcement comes.

After first announcement the stepper motor rotates

clockwise for 05 sec for opening of gate.

After 05 sec stepper motor rotates anticlockwise to

close the gate.

And second announcement comes.

Microcontroller sends signal to dc motor to start the

train.


11/31

FEATURES Single chip, 28 pin DIP, high quality voice recording andplayback solution.

No external ICs required.

Minimum external components Non -volatile flash memorytechnology.

100K year message retention (typical).

Single message of 20 to 60 seconds, with external resistorselection.

User friendly easy to use operation .


12/31

FEATURES (CONTD.)

8 different types of messages can be stored.

Level - activated recording and edge-activated playback

switches.

Low power consumption

Operating current: 25 Amp (typically, no load)

Standby current: 1Amp (typically, no load), automaticallypower down features for longer battery life chip enable pin forsimple message expansion single 5v power supply.

TICKET ANALYZER The ticket analyzer reads the date with id & password of the ticket.

If the ticket is valid the stepper motor rotates clockwise and at the same

time LCD displays WELCOME TO INDIA (as a station name).

In case of invalid ticket the LCD display shows SORRY INVALID and

the gate will not open.

If the user inserts invalid ticket/password more than thrice the buzzer starts

(for security purpose).


16/31

FEATURES OF TICKET ANALYZER

AT89c52 compatible processor with software lock.

Alphanumeric backlit (16x2) display for easy user interface.

Calculator type keyboard (4x4) for easy and faster operation.

Visual Indication of card status as well as error signaling (buzzer).

Electro magnetic Relay used for switching the gate.

Stepper Motor for Opening and Closing the gate.

GPSThe GPS receiver is a space

based satellite navigation system

that provides location and timeinformation in all weather

anywhere on or near earth.


20/31

WORKING PRINCIPLEGPS:

GPS satellites broadcast signals from space.

GPS receivers are used in mobile phones, vehicles,

marine navigation devices and military applications.


21/31

WORKING PRICIPLE (CONTD.) Need a minimum of 4 satellites for a position solution.

Good GPS receivers know when their measurementsare poor.

Fast speed.

Leads in right direction.

Makes navigation easier.


22/31

GSM GSM is a cellular network , which means that cell

phones connect to it by searching for cells in the

immediate vicinity.

It consists of helical antenna.


23/31

WORKING PRICIPLE GSM uses a combination of TDMA (time division

multiplexing)and FDMA(frequency devisionmultiplexing).

GSM provides voice and data services.

Maximum data rate 9600 bit/s

Maximum mobile terminal output power.

Maximum cell radius 30 km. Minimum cell radius 350m.

WORKING PRINCIPLE OF

UNMANNED RAILWAY GATE It consists of two weight sensors(switches).

One is placed before the railway gate and the anotherone is after the gate.

When the first switch is pressed by the train the gatecloses automatically using steeper motor.

When the train crosses over the second switche which

is placed after the gate, the gate opens automaticallyusing the steeper motor.


27/31

ADVANTAGES Reliability

Less maintenance

Cheaper

System doesn't disturb existing frequency.

Authentic in operation.


28/31

DISADVANTAGES GSM network is required.

External power supply is needed.

GPS and GSM is costly.

Requires careful operations.


29/31

APPLICATION

The micro controller is control the train to stop at railwaystation and open the compartment gate.

Automatic announcement inside the compartment when

train reach at Platform. Microcontroller based automatic controlling of train.

Checks the validity of the ticket.

GPS and GSM are used for finding the location of the

train.

Unmanned automatic railway gate is controlled by microcontroller.


30/31

CONCLUSIONThe present situation in train is using manual communication. Toreduce the manual efforts and human errors.

We are trying to implement a prototype model of the train systemwithin the limited available source and economy.

The system can be subjected to further development using advancedtechniques.

It may become a success if our project can be implemented in themodern train.
