RTIS

Real Time Train Information System

Challenges

  • Automatic acquisition of train movement data on Indian Railways for improving operational efficiency and quality of train positioning information for passengers ease.
  • Emergency messaging from loco pilot to control room.
  • Automatic plotting of control charts thereby reducing the possibility of human errors.
  • Reliable train movement updates from moving locomotive to central server without using any way-side infrastructure.

Automatic acquisition of train movement data on Indian Railways has always been a key requirement & the greatest challenge for accurate train speed and position reporting.

Goals

  • Automatic acquisition of train movement information through satellites and provision to relay the received information to Control Office Application (COA) for automatic plotting of control charts.
  • Installation of a device in the locomotives to detect position and speed using Geo-Positioning system.
  • Middleware / Application Software to send the train movement updates (Arrival/Departure/Run-through/Un-Scheduled stoppages and mid section updates) to Central Location Server (CLS).
  • Provision of transferring updates over a dedicated satellite based communication channel.

A major paradigm shift in legacy train operations by shifting the dependency of train movement control on the information manually relayed by the station master / section controllers to an automatic satellite based Real-time Train Information System (RTIS).



Our Solution

Smart Locomotive Device

  • Locomotive device comprising of GAGAN (GPS Aided Geo-Augmented Navigation System) to capture loco position, Satellite communication (SatCom) transceiver, 4G-3G to complement SatCom and 2.4 GHz RF/Zigbee module along with appropriate CPU, Memory, embedded operating system and application software. External Antennae for all modules housed in outdoor unit mounted on loco rooftop
  • Provision to support for NAVIC / IRNSS (Indian Regional Navigation Satellite System) is also in plans.

Satellite Transponder & Hub

  • Satellite Transponder and Hub (including NMS hardware & software) has been located in CRIS Datacentre to receive movement updates through SatCom.

Focus on Train Location & Speed

  • The application software in loco device determines train movement events i.e. Arrival, Departure, Run-through at stations using a pre-defined logic based on spatial coordinates.
  • Train speed received continuously every 30 seconds from GAGAN receiver.

Integration with COA

  • The events along with position/locations updates is communicated to a Central Location Server (CLS) using Satellite as well as 4G/3G mobile data service.
  • Central Location Server (CLS) hosted in CRIS DC processes the received data and relays it to Control Office Application (COA) for automatic plotting of control charts.
  • As COA is already integrated with National Train Enquiry System (NTES), accurate real-time information for passengers is obtained automatically.

Loco device Health Monitoring & SOS

  • Configuration Management System (LMCS) is utilized to monitor the health of loco device, managing its configuration & updating the software/firmware in the loco device.
  • Emergency messaging between Loco driver and control office is also implemented through RTIS.

Benefits
