Dans le domaine des transports mettant en œuvre par exemple des véhicules ferroviaires ou des véhicules correspondant à des bus, notamment des bus électriques, il est connu d'utiliser des coffres de traction de ces véhicules, ces coffres comprenant au moins un circuit de commande électronique et un terminal de communication propre à être connecté au circuit de commande électronique.In the field of transport using, for example, railway vehicles or vehicles corresponding to buses, in particular electric buses, it is known to use traction boxes for these vehicles, these boxes comprising at least one electronic control circuit. and a communication terminal suitable for being connected to the electronic control circuit.

En particulier, un tel circuit de commande électronique est propre à commander les moyens de traction du véhicule et à acquérir et mémoriser un ensemble d'informations associées à ladite traction et propre à être utilisées pour un traitement statistique d'une flotte de tels véhicules. Par exemple, un tel circuit est connu sous le nom commercial AGATE® (de l'anglais « Advanced Generic Alstom Transport Electronics).In particular, such an electronic control circuit is suitable for controlling the traction means of the vehicle and for acquiring and storing a set of information associated with said traction and suitable for being used for statistical processing of a fleet of such vehicles. For example, such a circuit is known under the trade name AGATE® (standing for “Advanced Generic Alstom Transport Electronics).

Il est connu de protéger un tel circuit de commande d'un échauffement dû à l'exposition du coffre de traction au soleil au moyen d'un dispositif métallique correspondant à un pare-soleil métallique tel que représenté sur la figure 1 représentative de l'état de la technique actuel. Un tel pare-soleil P_S comprend notamment deux pans P1 et P2 métallique dotés chacun d'une pluralité d'ouverture(s) d'aération O, les deux pans formant un toit recouvrant la surface supérieure du coffre de traction C_T.It is known to protect such a control circuit from overheating due to the exposure of the traction box to the sun by means of a metallic device corresponding to a metallic sun visor as shown in FIG. figure 1 representative of the current state of the art. Such a sun visor P_S comprises in particular two metallic sections P 1 and P 2 each provided with a plurality of ventilation opening (s) O, the two sections forming a roof covering the upper surface of the traction box C_T.

Toutefois, pour être utilisé à des fins statistiques, le circuit de commande est propre à être connecté à un terminal de communication tel un boitier codeur-décodeur propre à transmettre-recevoir les informations de traction au sein de un ou plusieurs signaux conforme(s) à un ou plusieurs protocole(s) donné(s). Pour ce faire, le terminal de communication est lui-même notamment propre à être connecté à un émetteur-récepteur de communication sans fil.However, to be used for statistical purposes, the control circuit is suitable for being connected to a communication terminal such as an encoder-decoder unit suitable for transmitting-receiving traction information within one or more compliant signals. to one or more given protocol (s). To do this, the communication terminal is itself in particular suitable for being connected to a wireless communication transceiver.

En d'autres termes, un tel pare-soleil métallique est propre à produire des perturbations électromagnétiques propres à détériorer le bon fonctionnement de l'émetteur-récepteur.In other words, such a metallic sun shield is suitable for producing electromagnetic disturbances suitable for deteriorating the correct operation of the transceiver.

Le but de l'invention est de proposer une solution de protection contre l'échauffement dû à l'exposition du coffre de traction au soleil, propre à garantir la compatibilité électromagnétique (i.e. le bon fonctionnement dépourvue de perturbation électromagnétique) de l'émetteur-récepteur associé au terminal de communication propre à communiquer les données du circuit de commande du coffre de traction du véhicule.The aim of the invention is to provide a solution for protection against overheating due to the exposure of the traction box to the sun, suitable for guaranteeing the electromagnetic compatibility (ie correct operation free of electromagnetic disturbance) of the transmitter. receiver associated with the communication terminal capable of communicating the data from the control circuit of the vehicle's traction box.

Sur la figure 2, le dispositif de protection 10 selon la présente invention est propre à permettre un passage d'un émetteur-récepteur 12 de communication sans fil associé à un terminal de communication, non représenté, propre à être connecté lui-même à un circuit de contrôle commande du coffre de traction d'un véhicule et comprenant par exemple une carte SIM (de l'anglais « Subscriber Identity Module »)On the figure 2 , the protection device 10 according to the present invention is suitable for allowing passage of a wireless communication transceiver 12 associated with a communication terminal, not shown, suitable for being itself connected to a control circuit the traction box of a vehicle and comprising for example a SIM card ( standing for “ Subscriber Identity Module ”)
