Definitions

  • the invention falls within the field of the distribution of consumables during the circulation of railway rolling stock.
  • the invention relates more particularly to the field of the distribution of consumables at the level of the interface between the wheels of the railway rolling stock and the rails of the railway track.
  • Each wheel 1 of railway equipment comprises a tread 2 in contact with the upper surface 5 of the rail 4, and a flange 3 which guides the wheel 1 by resting against a lateral face 6 of the rail 4.
  • a railway rolling stock comprises at least one grease distributor - called a flange lubricator - which continuously distributes a fatty substance between the wheels 1 of the equipment and the rails 4.
  • the distribution of grease thus makes it possible to generate a layer of fatty substance between the wheel flange 3 and the rail 4, which makes it possible to reduce the friction between said flange 3 and the rail 4, and to prevent premature wear of the wheels 1, or even the derailment of the rolling stock.
  • the rolling stock also includes at least one sand distributor - known as a sand pit - which distributes sand on an ad hoc basis between the tread 2 of the wheels 1 of the rolling stock and the rails 4, to increase the friction between the wheels 1 and the rail 4 in the event of external conditions unfavorable to the grip of the wheels 1, and in particular in the event of a thunderstorm.
  • a sand pit - which distributes sand on an ad hoc basis between the tread 2 of the wheels 1 of the rolling stock and the rails 4, to increase the friction between the wheels 1 and the rail 4 in the event of external conditions unfavorable to the grip of the wheels 1, and in particular in the event of a thunderstorm.
  • the level of these consumables in the reservoirs of the respective distributors is checked between two maintenance operations programmed in advance.
  • the invention therefore relates to a system for detecting any malfunction of a consumable dispenser making it possible to optimize the frequency of maintenance operations and to limit the impact of this malfunction on the movement of railway rolling stock.
  • the invention relates to a system for detecting a malfunction of a consumable dispenser for railway rolling stock, which dispenser comprises at least one reservoir and at least one dispensing device designed to dispense said consumable at the level of. 'at least one wheel of said railway material according to at least one determined distribution setpoint, the dispenser being in an operational state when at least the level of consumable in its tank is greater than a determined limit level, characterized in that the system comprises at least at least one level sensor of the consumable in the reservoir of the dispenser, and processing and control means which are connected to the level sensor and to the dispensing device, and which are configured to compare at least one measurement data coming from the sensor of level and the distribution setpoint, and to generate at least one datum indicating a malfunction of the distributor if the level sensor measurement data is not correlated with the distribution setpoint.
  • the invention relates to rolling stock comprising at least one consumable dispenser and at least one detection system as described above capable of implementing the detection method as described above.
  • figure 2 essentially represents one embodiment of the object of the invention but that there may be other embodiments which meet the definition of the invention.
  • the invention can be applied to all types of rolling railway vehicles provided with at least one consumable dispenser provided for distributing said consumable between the wheels 1 of the railway vehicle.
  • the implementation of the invention will be presented through a grease distributor at the level of the flange 3 of wheels 1 of the railway material.
  • the consumable of this dispenser being grease, it will be referred to hereinafter as “lubricator”.
  • the implementation of the invention will also be presented through a sand distributor between the rails 4 and the tread 2 of the wheels 1 of the railway rolling stock.
  • the consumable of this dispenser being sand, it will be referred to hereinafter as “sandbox”.
  • the train comprises several grease nipples and several sand pits making it possible to distribute grease and sand respectively at the level of the wheels 1 of the train.
  • the lubricator comprises a grease reservoir and a distribution device controlled by a control system on board the train.
  • This distribution device of known type, is configured to continuously distribute grease at the level of the flange 3 of the wheel or wheels considered 1.
  • the distribution setpoint implemented by the train control system generates a continuous distribution of grease, according to a determined theoretical flow rate and recorded in a database of said control system.
  • the sand pit comprises a sand reservoir and a distribution device controlled by the on-board control system on the train.
  • This distribution device of known type, is configured to distribute sand from time to time between the tread 2 of the wheels 1 and the rails 4 of the railway track.
  • the distribution setpoint implemented by the train control system generates a punctual distribution of sand, each punctual order of distribution sent by the control system distributing a theoretical calibrated dose of sand.
  • the train comprises a system for detecting at least one malfunction of the consumable distributor considered, that is to say at least one of the lubricators and / or at least one of the sand pits of the train. .
  • the detection system firstly comprises processing and control means connected to the various elements of the detection system, as well as to the distribution devices of the various distributors of the train.
  • processing and control means are included in the train control system.
  • the detection system further comprises a plurality of level sensors connected to the processing and control means, each sensor being installed in the reservoir of the distributor in question. Such a level sensor makes it possible to determine the filling level of consumable in the tank in question.
  • the processing and control means can thus receive the data transmitted by the level sensors. In the remainder of the description, these data coming from the level sensors will be called “sensor data”.
  • the detection system further comprises geolocation means connected to the processing and control means, which geolocation means are for example a satellite positioning system of the GPS type.
  • the detection system comprises wireless communication means connected to the processing and control means, making it possible to communicate with a terminal installed on the ground also provided with wireless communication means.
  • These wireless communication means are commonly called edge-to-ground communication means, and are implemented for example by combining cellular networks (in particular 3G and 4G protocols) and wireless communication protocols of the Wi-Fi type.
  • the processing and control means of the detection system determine the theoretical quantity of consumable distributed at a given time, from the consumable distribution instruction implemented by the train control system.
  • this first step E1 differs depending on whether the distributor is a lubricator or a sandbox.
  • the processing and control means determine the theoretical quantity of sand distributed by the distributor in question after each one-off order sent to said distributor. Thus, after n dispensing commands, the processing and control means determine that the theoretical quantity dispensed is n times the theoretical calibrated dose dispensed after a single dispensing command.
  • the processing and control means When the distributor is a lubricator, the distribution of grease being continuous, the processing and control means periodically determine the theoretical quantity distributed, over a period which depends on the type of lubricator and the speed of the train. When determining the theoretical quantity distributed at a given instant, the processing and control means determine the distance traveled by the train at this given instant via the geolocation means, by comparing the position of the train at this instant and the position of the train just before its departure. The theoretical quantity distributed at this given instant is then deduced by the processing and control means by correlating the theoretical grease delivery rate and the distance traveled by the train at this instant.
  • the processing means recover from the level sensor considered the sensor data indicating the actual level of consumable in the reservoir of the distributor considered.
  • the processing and control means calculate, for each distributor of the train, the difference between the real level determined in the third step and the theoretical level of the tank considered. If the absolute value of this difference is less than a determined threshold recorded in the memory space of the processing and control means, then the distributor in question is deemed to be functional.
  • the malfunction datum generated by the processing means is associated with the distributor considered. In this way, each defective distributor is assigned by the control processing means a malfunction datum indicating the type of malfunction determined.
  • the detection method of the invention comprises two additional steps E6, E7.
  • the processing and control means determine, via the geolocation means, the position of the train at the instant when a malfunction of at least one distributor is detected by the system of the invention.
  • the processing and control means then generate so-called location data, identifying the train and specifying in particular the position of said train and the type of malfunction detected.
  • the processing and control means send, via the wireless communication means, one or more location data to one of the terminals equipped with its wireless communication means and installed on the edge of track.
  • This terminal is then able to retransmit the location data to a maintenance center, generally the closest center and / or the best equipped to deal with the malfunction (s) detected, and if necessary to request a maintenance operation for the train considered.
  • the system and the method of the invention therefore make it possible to rapidly detect any malfunction of the consumable dispensers installed in a moving train, in particular the grease nipples or sand pits.
  • the frequency of maintenance operations is then optimized as necessary, the impact of malfunctions on the movement of railway rolling stock is limited, because a maintenance operation can be quickly triggered after any detection of such a malfunction.
