Solution Overview

Problem

The existing methods for deactivating Euro-balises in rail transport networks, such as using metal covers, are logistically cumbersome and require on-site storage, which is inefficient and difficult to manage, especially during construction sites where metal-free spaces are critical.

Innovation Solution

A system and method for selectively switching on and off a balise using a second induction device with a switch that can be wirelessly coupled to the balise, allowing for attenuation of the telepowering signal's induction effect below the activation threshold, eliminating the need for metal covers and enabling remote activation/deactivation without mechanical intervention.

AI summary

The present invention discloses a system and a method for selectively switching on and off a balise (10) arranged in a track body (2), comprising: a) the balise (10) which has a first induction device (16) for receiving a telepowering signal (18) emitted by a rail vehicle and a circuit (20) operable with the energy obtained from the telepowering signal (18) for emitting a balise telegram (22); and b) a second induction device (12) which has an openable switch (14) and is wirelessly coupled to the first induction device (16), wherein the balise (10) is able to transmit the balise telegram (22) when the switch (14) is open and a counter-induction signal can be generated in the second induction device (12) when the switch (14) is closed to at least partially attenuate the induction effect of the telepowering signal (18),so that the power induced in the first induction device (16) remains below an activation threshold of the circuit (20). In this way, the system and the method achieve the elimination of the problems associated with metallic covers by using a second induction device that is easy to install and can be permanently arranged on or in the balise. In addition, the second induction device is much easier to install and has permanent electrical properties, which is why a very robust design is also possible.
