6. ROLE OF ELECTRONICS AND
COMMUNICATIONS IN RINL - VSP
• ELECTRONICS AND COMMUNICATION IS THE
SMALLEST DEPARTMENT IN THIS FIRM YET
EFFECTIVE ONE.
• THIS DEPARTMENT IS KNOWNS AS TELECOM.
• TELECOM’S MAIN ROLE IS SURVEILLANCE
AND COMMUNICATION.
• SINCE STEEL PLANT IS A PRODUCTION
INDUSTRY ,COMMUNICATION IS IN THREE
PHASES.

1. GENERAL
PURPOSE
COMMUNICATION
2. PROCESS
COMMUNICATION
3. SIGNALLING AND
MONITORING
(SURVEILLANCE)

8. GENERAL PURPOSE COMMUNICATON
• THIS COMMUNICATION PROCESS CONSISTS OF
COMMUNICATION SYSTEMS LIKE,
• L.S.I.C - LOUD SPEAKER INTERCOM
COMMUNICATION.
• L.S.B.C - LOUD SPEAKER BROADCASTING
COMMUNICATION.
• LOCAL EXCHANGE.
• HOT LINES.
• VERY HIGH FREQUENCY SETS.

9. • FOR COMMUNICATION PROCESS ,
V.S.P CONSISTS OF SEVERAL LINES
OF WHICH,
• STEEL PLANT EXCHANGE – 4000 LINES.
• TOWNSHIP EXCHANGE – 3000 LINES.
• SMALL EXCHANGES – 1000 LINES.
• THERE ARE 11 SMALL EXCHANGES IN
THE PLANT EACH CONSISTING OF 1000
LINES.

10. PROCESS COMMUNICATION
• WALKY TALKIES.
• SUPERVISORY CONTROL AND DATA
ACQUISATION (SCADA).
• SHIFT INDICATING SIRENS.
• FIRE FIGHTING SYSTEMS.
• SCADA ARE PREFERABLY USED PLACES
WHERE RISK IS MORE AND ALSO THE
AREAS WHERE THE WORK IS HANDLED
WITH MEANS OF POWER , GAS , WATER.

11. HOW SCADA WORKS ?
• SCADA MEANS SUPERVISORY CONTROL
AND DATA ACQUISITION.
• SCADA IS A SYSTEM FOR REMOTE
MONITORING AND CONTROL THAT
OPERATES WITH CODED SIGNALS OVER
COMMUNICATION CHANNELS (USING
TYPICALLY ONE COMMUNICATION
CHANNEL PER REMOTE STATION).

12. • IT IS A CONTROL SYSYTEM CONNECTED TO
A REMOTE TERMINAL UNIT (OR) REMOTE
TELECONTROL UNIT [R.T.U.].
• RTU IS A DEVICE WHICH TRANSMITS THE
INFORMATION TO SCADA AND IN TURN
RECEIVES THE COMMANDS TO OPERATE.
• USES OF R.T.U.
• BENEFITS OF SCADA.
• SCADA CHANGED THE HUMAN MACHINE
INTERFACE IN INDUSTRIES.

13. SIGNALLING AND MONITORING
• I.P.V.M – INTERNET PROTOCOL VIDEO
MONITORING.
• C.C.T.V - CLOSED CIRCIUT TELEVISION.

14. ROLE OF IPVM AND CCTV
• CCTV IS AN OUT DATED TECHNOLOGY ,
USED IN OLDEN DAYS .
• CCTV IS USED FOR MOTION DETECTION
AND ALSO USED FOR SURVEILLANCE.
• IPVM IS THE LATEST TECHNOLOGY .
• IN THIS TECHNOLOGY , EACH CAM IS
ASSIGNED WITH AN IP ADDRESS AND
INTERNET /INTRANET DATA
CONNECTION AS PER REQUIREMENT .

15. • WE CAN ACCESS THE INFORMATION BY
IP ADDRESS FROM ANY PART OF THE
WORLD.
• THE FUCTIONING IS AS BELOW,
I.P.V.M ENCODER
SWITCH LINE INTERFACE
UNIT (L.I.U)NET SERVER
