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.

Claims

1. A device for communicating with human users of a TGV train and monitoring railway tracks along a TGV train line, the device being self-powered, the device comprising a plurality of communicating and monitoring terminals arranged at regular intervals along the tracks and dividing the TGV train line into monitoring sections of a defined length, with each of the terminals comprising:

an image-capturing module comprising a long-range thermal camera configured to monitor trains on the tracks,

a wireless communicating module that allows for communication between the terminals and with the human users of the train,

a module configured to store electrical power continuously supplying the image-capturing module and the communicating module,

a power-generating module configured to supply power to the module for storing electrical power comprising a means configured to recover the energy from the air displaced by the train running over the railway track, configured to permanent monitor by capturing images and making permanent wireless connections and images from the image capturing module available to the human users of the trains, the power generating module providing the power required by the communicating module and the module for storing electrical power;

the device further including a terminal built inside the cockpit of the train on which the images recorded by the cameras and transmitted by the Wi-Fi network are displayed;

the plurality of terminals being spaced along the tracks;

wherein the electrical power consumption of each module is about one kilowatt per day.

2. A device according to claim 1 wherein the means of recovering is a dynamic air turbine.

3. A device according to claim 1 wherein the means of recovering power is a wind turbine Converter without a propeller that adopts an electrostatic technology.

4. A device according to claim 1 wherein the wireless communicating module comprises an antenna making it possible to carry out two networks:

a main permanent Communications, transfer, data and distribution network of the images of the image-capturing module via internet connecting via a wireless connection, the terminals between them,

a terminal to an internet point of access and a at least one terminal to the train,

an autonomous local temporary network overcoming a failure in the permanent main network and able to distribute the views captured by the image-capturing means between each terminal and the train and from one terminal to the other.

5. A device according to claim 1 wherein the module for storing electrical power comprises:

electrical batteries,

reversible fuel cell, or

means for producing and storing compressed air.

6. A device according to claim 1 wherein the terminal comprises a mast sealed to the ground provided with a stem at the end of which is arranged the means for recovering.

7. A device according to claim 1 wherein the stem has an adjustable length.

8. A device according to claim 1 wherein the stem is linked to the mast in such a way as to be adjustable in height.

9. A device according to claim 1 wherein the module for communicating comprises a wireless communicating device of the Wi-Fi type that allows for communication between terminals or with the train.

10. A device according to claim 9 wherein the train is provided with a terminal built inside the cockpit on which the images recorded by the image-capturing modules are displayed.

11. A device according to claim 1 wherein the turbine is of the type without a propeller.

12. A device according to claim 1 wherein the mast comprises at its top end, the communicating module and the image-capturing module and, at the low end, a base for sealing to the ground.

13. An operating method of a device according to claim 1, the operating method comprising communicating to the terminal, the images deemed as suspicious by comparison with prerecorded images with their geographical location.

14. An operating method of a device according to claim 1, the operating method comprising in continuously communicating to the terminal, the images captured by the image-capturing modules arranged upstream and at a distance greater than or equal to the braking distance of the train.

15. An operating method of a device according to claim 1, the operating method comprising displaying on the terminal of a first train, the images of another train that preceded it or travelling in the opposite direction.

16. A device according to claim 1 wherein the regular intervals are two kilometers in length.

17. A device according to claim 1 wherein the image-capturing module comprise a GPS.

18. A device according to claim 1 further comprising Wi-Fi bridges.

19. A device according to claim 1 wherein the electrical power consumption of each terminal is less than the electrical power generation by each module.

20. A device according to claim 1 wherein the train is moving.
