DATA LOGGERS IN RAILWAY NETWORK



Data logger system is helpful in monitoring Railway Signal Control and Interlocking relays in

order to verify their operation, diagnose faults and in maintenance.


 Data logger logs the change of status of relays & voltages of analog channels connected to it and transmit event information to the central place to generate various exceptions, reports and other information by application software.


Data logger‘s are mandatory for all new relay interlocking (PI/RRI), EI installations and it is also

recommended to provide in all existing PIs/RRIs.


 Due to complexity of above interlocking systems and wiring sometimes it is very difficult to rectify the failures.


 So data logger can monitor these systems with a real time clock. 


Thus, it can be named as black box of S& T equipments and hence it is a vital tool for accident investigation.


 Data logger is used at stations/yards. Whereas in case of Auto Section & IBH Mini data loggers, called as Remote Terminal Unit (RTU), are used.



GENERAL SETUP OF DATALOGGER SYSTEM IN RAILWAYS

GENERAL SETUP OF DATALOGGER SYSTEM IN RAILWAYS



● Data logger is placed in the relay room of a station. 


The relays reflect the status of all assets present in the station yard. Data logger monitors the relay status and records the change of the asset status.



● Each data logger has multiple sets of data output ports for communicating the recorded

information to the Central/ Local Fault Analyzing System (FAS).
