Gajraj Suraksha senses pressure waves generated by the movement of elephants along the tracks. While explaining how exactly the mechanism works, officials revealed that 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 meters 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.
Over the past decade, about 200 elephants lost their lives due to collisions with trains, posing a significant threat to both wildlife and railway operations.
More than half of humanity's pre-modern inventions originated in China. But a few centuries ago, the Western world became the centre of innovation, and China seemed to stagnate for a long time. Today, however, all the indicators show that the West's dominance in this field has come to an end.
Digital trends sparked by the pandemic have fundamentally changed the way schools around the world operate. In developing countries, however, the digital revolution brought about by necessity has not only highlighted existing weaknesses in education systems, but has also widened the gap between students from different backgrounds.
A team of Chinese scientists are using artificial intelligence (AI) tech to accurately map out carbon emissions in big cities. This is an attempt that may help urban managers make more evidence-based plans in fighting global warming.
