Definitions

  • the invention relates to a method for checking the condition of a railway track and more particularly relates to the identification of faults detected by control equipment on board a car traveling on the railway track to be checked to allow maintenance teams to subsequently find these faults; the invention also relates to a control system for the implementation of this method.
  • All of these control means are used to detect, as the car progresses, specific types of fault: internal cracks for the ultrasonic detectors, cracks opening onto the surface of the tread for the detectors eddy current, etc ...
  • a computer processing system is also on board to process the information delivered by all the sensors, correlate them and thus characterize the nature of the fault while distinguishing among the signals received those which correspond to a singular point (joint or rail jointed, joint welded) and not a defect.
  • Other information relating to the general condition of the railway can be collected by suitable means and processed by the computer, such as for example the stability of the track or the quality of the shunting of the rails by the axles which conditions the automatic signal operation.
  • the computer is associated with means of recording and displaying all this information, such as for example a printer which delivers a succession of messages which will be used subsequently by a maintenance team.
  • An operator supervising the taking of data can also, via a keyboard, enter information indicating singular points of the track (tunnels, switches) facilitating the identification of faults by the maintenance team.
  • the invention aims to allow automatic entry of singular points facilitating the location of paint marks.
  • the invention therefore relates to a method for checking the condition of a railway track of the type consisting in moving the control means on a car traveling on said track and in recording the signals emitted by said control means as and as the progress of said car progresses, characterized in that, by pointing an on-board radar on said car to characteristic structures located along and in the vicinity of said track, recording the echo signals corresponding to these characteristic structures, simultaneously with said transmitted signals, to contribute to the subsequent identification of the faults detected on said railway.
  • the invention also relates to a system for controlling a railway track comprising a car traveling on said track in which are installed means for continuously monitoring said track and means for recording the signals delivered by said control means, characterized in that said car carries at least one radar device whose antenna is oriented in a predetermined direction corresponding to the position of characteristic structures located in the vicinity of the track and that said recording means are connected to record the echo signals developed by the radar correlatively to the signals delivered by the control means.
  • the described control system is installed on board a car 11 moving on a railroad track 12a to be checked.
  • Two alignments of catenary poles 13a, 13b are respectively established along two parallel railways 12a, 12b.
  • a number of sensors 14, 15, 16, 17 ... are installed in the car to control the rails, these are mainly ultrasonic or
  • the signals emitted by these sensors are processed and managed by a computer 20 which controls a printer 21 whose role is to record and display the information signaling the faults and their approximate location by singular points. Some of these singular points can be recorded directly by an operator inspecting the lane from the car 11. The operator then uses a keyboard 22 coupled to the computer-printer system.
  • the computer also controls a marking device 23 projecting a small amount of paint onto the railway each time a defect is detected by one of the sensors 14 - -17 and recognized as such by the computer, according to known criteria and analysis procedure, which are not part of the invention.
  • the car 11 carries at its upper part, at least one and preferably two radar antennas 25a, 25b, here in the form of paraboloids.
  • antennas are oriented in predetermined directions (symmetrically on either side of the car and towards the front) corresponding to the possible position of characteristic structures located in the vicinity of the track.
  • the antenna 25a is pointed towards the upper part of the catenary poles 13a and receives the corresponding echoes while the signals possibly emitted by the antenna 25b do not give rise to any usable echo.
  • the antenna 25b providing the echo signals representative of the presence of the catenary 13b.
  • Each antenna 25a, 25b is oriented so that its radar beam is more particularly directed towards the anti-swayers 26 of the catenary poles of the corresponding alignment.
  • the radar equipment connected to the antennas is conventional and includes means for measuring the Doppler effect resulting from the movement of the car 11.
  • the orientation of the antenna being fixed and the spacing b of the catenary poles relative to with the railway varying little, the distance d separating the anti-swinging from the catenary poles of the antenna during the development of the echo is a constant and the corresponding frequency variation fo is known if the speed of car 11 is stabilized at a predetermined value (in the order of 40 km / h in practice).
  • the system can therefore include, for example, an HF generator 28 connected to a transceiver device 29, the echo signal output of which is connected to frequency comparator means 30 also connected to the generator 28.
  • Any predetermined frequency difference fo is interpreted as the detection of a catenary pole and causes the transmission of a command to pilot the printer 21.
  • the system is programmed to automatically correct the location of the catenary of the distance a due to the orientation towards the front antenna (see Figure 3). Once this systematic error correction has been made, the residual location error practically depends only on the variations in the distance of the anti-balancers from the catenary poles relative to the track (distance b); it is of the order of 1 to 2 meters. Of course, one could provide other antennas 25 pointed towards other characteristic structures such as bridges and tunnels.
