Definitions

  • the present invention relates to a particular system fitted to a railway vehicle intended to run on a railway track comprising at least one tunnel.
  • a pressure wave protection system configured to hermetically isolate an interior of the rail vehicle from an exterior of this rail vehicle when this system protection is activated.
  • beacons are generally placed on the railway, near the entrances, and generally exits, of the tunnels.
  • the rail vehicle then comprises means for detecting these beacons.
  • a beacon is detected, that is to say when the rail vehicle arrives near a tunnel equipped with this beacon, a signal is transmitted to the driver of the rail vehicle, so that he manually actuates the system of protection, before the railway vehicle enters the tunnel.
  • the object of the invention is in particular to remedy this drawback by providing a railway vehicle provided with a protection system whose reliability is improved.
  • the rail vehicle according to the invention makes it possible to substantially reduce the comfort degradations linked to pressure waves.
  • the activation of the protection system being linked to geolocation, there are no longer activation faults linked to an absence of a beacon or an absence of activation action by the driver.
  • the system according to the invention is therefore very reliable.
  • the system according to the invention does not depend on the infrastructure of the railway.
  • the invention can be implemented easily, even when the rail vehicle travels in several countries, the geolocation systems not being dependent on the countries and their infrastructures. Consequently, the system according to the invention is suitable for all countries without requiring adaptation.
  • FIG. 10 There is shown in the figure a rail vehicle 10 according to an exemplary embodiment of the invention, shown schematically and partially.
  • the railway vehicle 10 is intended to travel on a railway track comprising at least one tunnel, and generally a plurality of tunnels.
  • the rail vehicle 10 comprises a system 12 for protection against pressure waves, configured to hermetically isolate an interior of the rail vehicle 10 from an exterior of this rail vehicle 10 when this protection system 12 is activated.
  • Such a protection system 12 is capable of taking airtight isolation measures from any passage between the interior and the exterior of the rail vehicle 10, so that a pressure change outside the rail vehicle 10 does not have repercussions. not inside.
  • the protection system 12 comprises hermetic sealing means for ventilation pipes opening to the outside.
  • the rail vehicle 10 comprises an air conditioning system 14, this air conditioning system 14 conventionally comprising air circulation ducts, some of which open outside the rail vehicle 10.
  • the protection system 12 then comprises means for closing at least one air circulation pipe of the air conditioning system 14, and preferably all the air circulation pipes opening to the outside.
  • These sealing means comprise for example a valve by air circulation pipe to be closed, each valve preferably being provided with a seal to allow the most airtight sealing possible.
  • the rail vehicle 10 comprising access doors from the outside, these access doors are provided with seals allowing hermetic closure of these access doors.
  • the protection system 12 comprises means for inflating each seal.
  • the rail vehicle 10 only has sealed windows, devoid of opening means. Otherwise, means will be provided for automatically closing the windows, controlled by the protection system when it is activated.
  • the rail vehicle 10 according to the invention also comprises geolocation means 16 providing instant geolocation coordinates of the rail vehicle.
  • geolocation means are conventional, and will therefore not be described in detail.
  • the invention uses the same geolocation means as those usually present on railway vehicles of the prior art.
  • the geolocation means 16 are formed by a conventional geo-positioning satellite system (GPS).
  • GPS geo-positioning satellite system
  • the rail vehicle 10 furthermore comprises a database 18 comprising, for each tunnel of the railway, fixed geolocation coordinates of an entry point of this tunnel.
  • Each entry point is chosen beforehand during the configuration of the database 18, on the track near a corresponding tunnel.
  • each entry point is chosen upstream of the tunnel, at a sufficient distance leaving sufficient time to perform the hermetic isolation of the vehicle 10 before the effective entry into the tunnel. This time is for example approximately 5 seconds,
  • Said sufficient distance is easily calculated by knowing the speed provided for the rail vehicle 10 at the entrance to the corresponding tunnel.
  • the speed taken into account in this calculation is, for example, equal to the speed limit provided for on the railway line at the entrance to the tunnel.
  • the database 18 also includes, for each tunnel, length information, corresponding in particular to the length of the tunnel, preferably added to said sufficient distance.
  • the railway vehicle 10 also comprises means 19 for comparing the instantaneous coordinates with the fixed coordinates.
  • the comparison means 19 compare in real time the position of the rail vehicle 10 with respect to the tunnels and more precisely to the entry points.
  • the comparison means 19 are configured to indicate when the instantaneous geolocation coordinates of the rail vehicle 10 correspond substantially to the fixed coordinates of the entry point of one of the at least one tunnel. In other words, the comparison means 19 indicate when the rail vehicle 10 arrives at an entry point.
  • the rail vehicle 10 further comprises means 20 for controlling the protection system 12, configured to automatically activate the protection system 12 when the instantaneous geolocation coordinates of the rail vehicle 10 correspond substantially to the fixed coordinates of the entry point of one of the at least one tunnel.
  • the rail vehicle 10 could include a manual activation system as in the prior art.
  • the rail vehicle 10 includes an odometer 22.
  • an odometer 22 is conventional and will not be described in more detail.
  • the state-of-the-art railway vehicles are usually already equipped with such an odometer, suitable for calculating the mileage traveled, in particular by acquiring and processing the signals from its sensors on axles.
  • the control means 20 are then configured to deactivate the protection system 12 when the odometer 22 has measured that the railway vehicle has traveled, since the activation of the protection system 12, a predefined distance based on said tunnel length information. corresponding.
  • this length information is based on the length of the corresponding tunnel, and corresponds for example to the sum of this length of the tunnel, of said sufficient distance defined between the entry point and the tunnel, and preferably of an additional distance.
  • the additional distance leaves a time of one to two seconds after leaving the tunnel to deactivate the protection system 12.
  • Said additional distance is easily calculated by knowing the speed provided for the rail vehicle 10 at the exit of the corresponding tunnel.
  • the speed taken into account in this calculation is, for example, equal to the speed limit provided for on the railway line at the exit of the tunnel.
  • This embodiment is advantageous in that the geolocation system 16 is not active in tunnels, so that it is more reliable to rely on the odometer 22 to provide for the deactivation of the protection system 12.
  • the database 18 also includes fixed coordinates of such exit points.
  • This variant can be preferred when using a high-performance geolocation system active even in tunnels.
  • the invention makes it possible to carry out a method of protection against pressure waves, which will now be described.
  • the method comprises, when the instantaneous geolocation coordinates of the rail vehicle correspond substantially to the fixed coordinates of the entry point of one of the at least one tunnel, the control of the activation of the protection system 12.
  • the method includes deactivation of the protection system 12 when the odometer 22 has measured that the rail vehicle has traveled, since the activation of the protection system, a predefined distance corresponding to the length information.
