PRS :-PRS is computerized reservation system for any train from anywhere in country, launched on 15th November 1985.

The system works both on the optical fiber cable & the microwave communication at the data rate of 4.8 kbps or 9.6 kbps.

END TERMINAL

Equipment used in PRS:-

Modem means modulate and demodulate.We can use modems to log on to micro, mini, main frame computer for line processing.

It is the process of converting multi inputs signal into one output signal

The end terminal of the system is the station where tickets are to be printed out. It consists of a company system with a dot matrix printer

It is a computerized system used to issue the tickets for the unreserved compartments of train .

The system is programmed according to the type of the train.

The system works at the data rate of the 64 kbps .

Baseband Modem

Router

It is the end point of the network from where tickets are to be printed out .It consists of a monitor, a keyboard and a matrix printer.

This device is used to interconnect user devices with each other over 2-wire circuits. The ports available for the interfacing are G-703, V.35, V.24, V.11.

Router is used to detect the quality samples from different branches and start sending data from that branch which has good quality ratio. The router has 25 input terminals, which means that 25 branches can be connected to the router. 

RRI PANNEL :-

It will display the position of trains, signals aspects &point conditions. The panel contains switches for performing different operations.The panel contain 2 seven segment display .One speaker is also placed for making necessary appointments.

The Third Route Is Set Up:-

Two Routes Freed For Up And Down Train To Procced:-

RAILTEL :-

Rail net is an internet for railways.Important information and data can be transformed from one division to other division.

Within less time in railways current position of train can be obtained in PRS.

The connectivity of different reservation take place with the help of rail net.

CONCLUSION:-

These 3 aspect which i presented in front of you are the building block of railway.

Which deals with detail study of signal, control and communication.

Which in turn help me to develop a practical view of the subject which I have learnt in my engineering period.
