  • Implemented High End Data presentation tools like Video Walls, Multi-Monitor Systems and Web Servers
  • Proven Point Health Monitoring Systems (Event Loggers, Mini Loggers and Relay Room Loggers), Battery Monitoring Systems and Fuse Monitoring Systems.
  • Proven ‘Yard Validation/System Integrity Testing' for stations.

Data Logger:

Data Logger is a Microprocessor based system which acts like a Black-Box, and facilitates monitoring of various Railway Signalling Control relays, interlocking relays, track circuits, point machines and other essential parameters. This also facilitates online/offline pictorial representation of train movements, verification of relay room maintenance, station master operations and any unfrozen faults/events during the day to day to operations of Railway staff. These reports and data can be viewed locally in a PC, or in a remote location through networking. This enables accurate supervision of operation, and greatly helps in planning future requirements.

  • Standard high speed Industrial based Multi core Processor system
  • Supports optically isolated digital inputs from minimum 64 inputs to maximum 4096 digital inputs @ 16 mSec scan rate for Dataloggers, and up to 128 digital inputs for RTU.
  • Supports Galvanic isolated analog inputs from minimum 8 inputs to maximum 96 analog inputs @ 1 second scan rate and up to 32 analog inputs for RTU
  • Supports more than 30 lacks event storage capacity and can be retrieved to any secondary memory for analyzing data
  • Supports printer interface to print hard copy of online/ off line data
  • Supports minimum 8 serial communication ports and can be expandable up to 16 ports
  • Supports Leased Line dual modem/ E1 to RS 232/ E1 to E1 communication techniques to establish the communication with various Railway communication networks.
  • Supports Potential free contacts to monitor & control Railway relay room equipment from central place.
  • Supports to monitor Points & Signaling gear system to avoid collision of trains
  • Facilitate audio visual alarms on any exceptions and faults
  • Facilitates local LCD display to monitor the operated events and other parameters.
  • Facilitates local keypad to scroll down & see the menu operations

Front End Processor

Front end Processor is a Microcontroller based system which acts like block box to collect the data Loggers information through railway network, sends to Central Monitoring system

  • Standard high speed Industrial based Multi core Processor system
  • Supports more than 50 lacks event data storage capacity.
  • Supports minimum 8 serial ports to maximum 16 serial ports
  • Supports Leased Line dual modem/ E1 to RS 232/ E1 to E1 communication techniques to establish the communication with Data Logger network in Ring topology.
  • Supports minimum 2 serial ports to establish communication with multiple CMU's

Central Monitoring Unit:

Central Monitoring Unit is a high end desk top system with latest configuration to establish communication with Front End Processor and stores the entire data logger's data for more than 3 months. It facilitates to monitor and analyze the online/ offline simulation of train movements & generates the general and exceptional reports at section level. It facilitates to push the collected information to Local server & web server through LAN to extend the data monitoring facility to Divisional/ Zonal / Railway board level.

  • Online / Offline monitoring of train movement, Points & Signaling gears simulation
  • Online monitoring of Digital and Analog inputs
  • Online monitoring of complete network status
  • Monitoring, verification and analysis selective period data
  • Online / Offline analog & digital graphical mimic display for the selective station
  • Facilitates auto back facility to take the back up of previous data for future analysis purpose.
  • Generates email/short message (SMS) to field staff and higher officials on any exception cases or faults occurrences
  • Facilitates the Network monitoring screen for easy monitoring of networking
  • Facilitates the Signal Monitoring System screen for easy monitoring of signaling system
  • Facilitates the Power supply Monitoring system for easy monitoring of Analog signal conditions
