DATA LOGGERS MODES

• DATA LOGGERS ARE USED IN TWO DIFFERENT MODES
• AS STAND ALONE UNITS MOSTLY IN LARGE SIGNALLING
  INSTALLATIONS.
• AS NETWORKED SYSTEMS WITH A CENTRAL MONITORING
  AND CONTROL FACILITY AT THE HEAD QUARTERS WITH
  MULTIPLE ACCESS AS DESIRED.
• IN BOTH CASES, EACH DATALOGGING EQUIPMENT
  CALLED YARD MASTER IS PROVIDED WITH A FAULT
  ANALYSIS APPLICATION SOFTWARE IN A MONITORING
  P.C. CALLED YARD VIEWER.

STAND ALONE DATA LOGGER SYSTEM

• THIS CONSISTS OF
• DATA LOGGER EQUIPMENT (DLE) ON A RACK.
• DIGITAL INPUT CABLE TERMINATION(DITC) RACK.
• A MONITORING P.C. LOADED WITH FAULT ANALYSIS
  SOFTWARE .
• A FAULT INDICATOR UNIT FIXED AT A CHOSEN
  LOCATION.
• POWER SUPPLY DLE WORKS ON 24V. D.C. AND THE P.C.
  ON 230V. A.C.

DATA LOGGER NETWORK

• THIS IS MADE UP OF
• INDIVIDUAL DATA LOGGER UNITS, ONE AT EACH
  STATION, INTERCONNECTED THROUGH MODEMS AND LEASED
  LINES IN A DAISY CHAIN FASHION UP TO 32 NUMBERS.
• A NETWORK MANAGER CALLED FRONT END PROCESSOR(FEP)
  AT THE CENTRAL LOCATION.
• A CENTRAL MONITORING UNIT (CMU) AT THE FEP.
• A FAULT INDICATOR UNIT(FIU).
• POWE SUPPLY DLE AND FEP WORK ON 24V.DC, WHILE
  CMU WORKS ON 230V AC.

• CENTRAL MONITORING UNIT
• CMU is a desktop PC with YARD VIEWER software
  installed in it.
• When connected to a StandAlone Data Logger it
  monitors a single station yard.
• When connected to FEP of a Network it monitors
  data of all connected stations of network.
• It stores data acquired from the Station/Cabin
  yards in standard database files.
• It acts as an interface between the user and the
  System.

YARD VIEWER UTILITY

• Uses data for
• HEALTH CHECK OF ALL GEARS(SIGNAL, POINT, TRACK)
• STAGE-WISE MONITORING OF ROUTE
• FINDING FAULTY OPERATIONS (PANEL OPERATOR)
• TRAIN LATE START
• TRAIN SPEED MONITORING
• IDENTIFYING SPAD CASES (SIGNAL PASSING AT DANGER)
• GRAPHICAL SIMULATION OF TRAIN MOVEMENTS
• GRAPHIC VIEW OF MONITORED POWER SUPPLY ON-LINE OR
  OFF-LINE

ROUTE SEQUENCING

• WHEN STAGE-WISE RELAYS CURRENT STATUS IS MATCHED
  WITH THE EXPECTED STATUS THEN ROUTE INITIATED
  MESSAGE IS DISPLAYED.
• WHEN ROUTE IS NOT SET DUE TO A RELAY STATUS IN
  THE GIVEN SEQUENCE IS NOT MATCHED, THEN ALARM IS
  GENERATED FOR THAT PARTICULAR RELAY.
• MESSAGE IS DISPLAYED TO SHOW THAT ROUTE IS NOT
  INITIATED FOR THAT PARTICULAR ROUTE.
• BY CLICKING ON THE FAULTY RELAY, CIRCUIT
  ASSOCIATED THAT RELAY IS DISPLAYED FOR FURTHER
  ANALYSIS.
• THIS HELPS TO NARROW DOWN THE POSSIBLE ERROR IN
  THAT PARTICULAR ROUTE.

FUSE FAIL MONITORING UNIT (FFMU)

• FFMU IS USED TO REDUCE THE HALTING / FAILURE OF
  THE
• SIGNALLING SYSTEM.
• WHEN MAIN FUSE BLOWS, REDUNDANT FUSE (OF SAME
  RATING)
• WILL BYPASS THE MAIN PATH AND SYSTEM WILL
  FUNCTION NORMAL.
• GENERATES AN ALARM THROUGH LED RELAY (POTENTIAL
  FREE)
• FOR LOCAL AND REMOTE ANNUNCIATION.
• ONE COMMON POINT FOR SENSING IS TAKEN FROM SUPPLY
  BUS BAR
• AND OTHER POINT IS TAKEN AT THE OUTPUT OF
  RESPECTIVE FUSE.
• CURRENT DRAWN BY FFMU IS VERY MUCH LESS THAN
  1mAMPS.
• FFMU OPERATES ON 24V DC POWER SUPPLY.
• EACH FFMU SCALABLE TO MONITORING UPTO 16 FUSES.
