Abstract
A device for communicating and monitoring railway tracks includes a plurality of communicating and monitoring terminals arranged along the tracks. Each of the terminals includes an image-capturing module, a wireless communicating module that allows for communication between the terminals and with a train, and a module for storing electrical power continuously supplying the image-capturing module and the communicating module. Each terminal also includes a power-generating module for supplying the module for storing electrical power. The power generating module recovers energy from the air displaced by the train running over the railway track. The device permits permanent monitoring by capturing images and makes permanent wireless connections available to the trains.
