1. Railway Signalling Products Division • WELCOME ….. • DATA LOGGER PRESENTATION ON – 25.04.07 • I R I S E T

2. 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.

3. 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.

4. STAND ALONE DATA LOGGER SYSTEM Inkjet Printer 230VAC UPS L M U Note:– RS232 without modem upto 15metres. -- 2/4 wire modems are to be used for longer distance. 230VAC, 50Hz  RS232 Dot Matrix Printer 24V BATTERY 24VDC Charger FIU D L E

6. DATA LOGGER ENCLOSURE • THIS ACCOMODATES THE FOLLOWING: • POWER SUPPLY MODULE – 1. • PROCESSOR MODULE – 1. • COMMUNICATION MODULE – 1. • GROUP SELECTION / TELECOMMANDS MODULE – 1. • DIGITAL INPUT MODULES – 4 (FOR 1024 DIs EACH). • ANALOG TO DIGITAL CONVERSION MODULE – 1. • THE NUMBER OF DIGITAL INPUT MODULES VARIES • ACCORDING TO THE DI s TO BE MONITORED.

7. Fault Indicator Unit (FIU): HEALTHY SUPPLY SYSTEM ANALOG SIGNAL TRACK POINT

8. 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.

10. Front End Processor (FEP)

11. FRONT END PROCESSOR • THIS CONSISTS OF THE FOLLOWING: • POWER SUPPLY MODULE – 1No. • COMMUNICATION MODULE – 1No. • PROCESSOR MODULE – 1No. • MODEMS - 2Nos. • POWER SUPPLY: THIS WORKS ON 24V DC +20%, -30%.

12. CENTRAL MONITORING UNIT

13. 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.

14. CURRENT LOOP RTU DATA LOGGER

15. RTU RACK • THIS ACCOMODATES THE FOLLOWING: • POWER SUPPLY MODULE – 1. • PROCESSOR MODULE – 1. • COMMUNICATION MODULE – 1. • DIGITAL INPUT MODULES – 1 (1024 DIs). • ANALOG TO DIGITAL CONVERSION MODULE – 1. • DIGITAL INPUTS CAPACITY – 64. • ANALOG INPUTS CAPACITY – 16.

17. 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

18. ON LINEANIMATION

19. OFF LINE ANIMATION

21. 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.

26. 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.
