INTRODUCTION

RAJDHANI EXPRESS

Rajdhani express is a special type of train.Guard

is the controller of the running train.Train is

controlled by the help of whistle or flag (red as

well as green).

There are two set systems for communication

between guard and driver:----

(A) VHF- it tends to very high frequency.it’s

range

is 30-300MHZ. Example:-walkie-talkie set 5

hrs 5 watts(the range of walkie-talkie is upto

2km). It is also called line of sight

communication.it means that if driver and guard

are not in same line then communication is not

possible.

(B) POINT-TO-POINT COMMUNICATION-

A point-to- point connection refers to a

communications connection between two

nodes or end points. An example is a telephone To be

continued….

INTRODUCTION

A pair of wire between guard and

driver, both have telephone. This

telephone is called magneto

telephone which is very authentic.

MAGNETO TELEPHONE—it has

a handle when handle is rotated

then mechanical energy is

converted into electrical energy by

the help of generator which is

available in this telephone..Ringing

voltage range is—60-70 volts

IPDSLAM

It connects multiple customer digital subscriber line (DSL)

interfaces to a high-speed digital communications channel

using multiplexing techniques.

Customers connect to the DSLAM through ADSL modems or

DSL routers, which are connected to the PSTN network via

typical unshielded twisted pair telephone lines. Each DSLAM

has multiple aggregation cards, and each such card can

have multiple ports to which the customers lines are

connected.

EXCHANGE

It is an Israel system. It is a

1200 line exchange which is

called SPC or Stored

Program Control. It is also

called ISDN type exchange.

Technical Description of

System:-The Coral Flexi-

Com digital communications

switching system employs

the latest advancements in

telecommunications

technology.

OPTICAL FIBER CABLE An optical fiber cable is a cable containing

one or more optical fiber. The optical fiber

elements are typically individually coated with

plastic layers and contained in a protective

tube suitable for the environment where the

cable will be deployed.

Optical Fiber communication:-Glass fibers

carrying information at frequencies of visible

light spectrum.

Advantage:- 1. No induction effect.

2. Low transmission loss.

3. High bandwidth.

4. Speed of communication

is more.

5. Less weather effect.

6. Safety and security is

more.

Disadvantage:- 1. Requirement of high

skilled staff.

PUBLIC ADDRESS(PA) AND TRAIN INDICATION BOARD(TIB)

ANNOUNCEMENT SYSTEM:-

The PA closely integrates the audio and

visual functions for conveying the desired

information to passengers. The system

generally consists of:-

A. Visual Equipment:-Visual equipment,

consisting of saloon displays and head

code displays, conveys journey-related

information for the convenience of

passengers.

B. Audio equipment: Audio equipment are

used for automatic and manual

announcements to passengers travelling in

the train.

TIB: -(TRAIN INDICATION BOARD)

Train Indication Boards are provided at

entrance / exit and other public utility

places of railway station premises. These

are the display devices which gives the

information regarding Train name and no.

DATA LOGGER A data logger (also datalogger or data

recorder) is an electronic device that records

data over time or in relation to location either

with a built in instrument or sensor or via

external instruments and sensors.

Data loggers vary between general purpose

types for a range of measurement applications

to very specific devices for measuring in one

environment or application type only.

DATA LOGGER

WORKSTATION

IP EXCHANGE

It tends to internetwork packet exchange.

Packet based communication, enabling use

of common infrastructure for data, voice

and video communication.

It has two types of switches:-- (a)

Ethernet port

(b) optical

port

Upto 100 meters Ethernet port is used and

more than 100 meters transmission is

lossed so optical port is used.

Power over Ethernet is used for giving

power to the IP devices.
