Gajraj Suraksha

About Gajraj Suraksha:

• It uses an AI-based algorithm and a network of sensitive optical fibre cables to detect elephants getting close to railway tracks.
• It aims to address the issue of elephant fatalities resulting from train accidents.
• Working
  • Gajraj Suraksha senses pressure waves generated by the movement of elephants along the tracks.
  • As elephants move, the optical fibres detect vibrations caused by their footsteps.
  • These vibrations trigger signals within the optical fibre network, enabling the system to identify the presence of elephants up to 200 metres ahead of their arrival on the track.
  • The OFC-based Intrusion Detection System works by sending alarms to station masters whenever movement is detected along the tracks.
• The network is designed in such a way that it can track the movement of the elephant with great accuracy and report it to nearby station masters.
• This allows them to promptly inform locomotive drivers in the affected areas.
• This quick communication ensures that trains can be slowed down or stopped, preventing potential collisions with elephants.
• Indian Railway is planning to introduce this system in West Bengal, Odisha, Jharkhand, Assam, Kerala, certain parts of Chhattisgarh, and Tamil Nadu.
