Definitions

  • the invention relates to a method for checking the integrity of a vehicle association according to the preamble of claim 1 and a device for Execution of the method according to the preamble of claim 5.
  • a typical axle counting device as is known, for example, from an article by K. Mindel with the title " Method for the automatic correction of axle counting errors" , Signal and Draht, 86 (1994), pages 5 to 8, comprises several metering points arranged along the route and an axle counting evaluation device - usually housed in a signal box - which evaluates the counting pulses transmitted by the metering points.
  • Each metering point in turn consists of an electronic junction box that is connected to one or two rail contacts. If fewer axles are counted at the end of a route section in a vehicle group than at the beginning of the route section, it can be assumed that the vehicle group has been separated in the area of the route section.
  • axle counting devices with their numerous rail contacts and the necessary cabling, however, cause high costs, both during the initial installation and during maintenance and at necessary track work.
  • a method according to the invention which solves this problem is the claim 1 to be removed; an inventive device for performing the method is the subject of claim 5.
  • first means exert a pressure pulse on a rail.
  • Second means arranged on the same vehicle register in the Spreading pressure impulses.
  • An evaluation device uses of the pressure pulses registered by the second means, of how many Axes of the vehicle association that exercised by the first means Pressure pulses are reflected. The number of Axes will then be routed, for example, by radio or in the track transmitted to an interlocking.
  • the method according to the invention therefore does not require any track-side Facilities.
  • the vehicles - preferably the locomotives only a few additional devices required.
  • One for control and Evaluation of the first and second means preferably to be used in terms of signal technology secure computer is already available on modern locomotives, so that there are no significant costs. Neither will further, arranged on other vehicles of the vehicle association Devices (radio transmitters etc.) are required.
  • the determined number of reflective axes in the vehicle itself further evaluated.
  • the evaluation device is checked by the driver or directly by one of the drivers before the start of the journey Central unit (e.g. signal box) fed the target number of axles of the vehicle association. The number of axes determined after the start of the journey deviates from this If the number of axles decreases, the evaluation device initiates an alarm action.
  • This alarm action can e.g. B. the output of an acoustic and / or optical signal to the driver or around the Act initiate emergency braking.
  • the sending a corresponding alarm message to a control center, e.g. B. a signal box be prompted. This means that this variant does not necessarily require a central office participate to ensure the security of the operation.
  • Fig. 1 shows a motor vehicle TFZ, which at one end of a several vehicles existing vehicle association. Whether and in which direction the vehicle group is moving is irrelevant.
  • a A pressure pulse generator DIG is attached to the axle of the TFZ motor vehicle.
  • DIG is attached to the axle of the TFZ motor vehicle.
  • an electro-mechanically operated mallet so close to the axis is appropriate that it strikes against a trigger signal against the axis. Of the structure-borne noise generated by the impact of the flail is transmitted from the Axle over the wheels on the rails.
  • Such a pressure pulse generator can also directly above the surface of a or both rails can be arranged.
  • the mallet strikes immediately onto the rail surface and thus produces a much stronger one Pressure impulse as if the vehicle axis was struck.
  • the pressure pulse generated by the pressure pulse generator spreads as structure-borne noise in the longitudinal direction of the rails. Attenuation of structure-borne noise in steel rails is known to be very weak, so that the pressure pulse too can still be registered a few hundred meters away from the pressure pulse generator is. At the points where vehicle wheels rest on the rail there is a disruption due to the very high contact force acting there the pressure pulse propagation. This disturbance causes partial reflection of the pressure pulse.
  • a Pressure pulse sensor DIS attached to the vehicle.
  • the embodiment is the pressure pulse sensor DIS on one of the Axles of the TFZ locomotive.
  • An arrangement is also possible, for example, where the pressure pulse sensor DIS like a sliding contact directly on the Rail rests.
  • Pressure pulse sensors designed as structure-borne sound microphones are familiar to the person skilled in the art, without this being of any particular significance Evidence is required.
  • the sensor signals generated by the pressure pulse sensor DIS are an evaluation device AUSW fed. Based on the sensor signals, this determines How many axes of the vehicle group that of the pressure pulse generator applied pressure pulse is reflected.
  • a central processing unit CPU transmits a pressure pulse control unit DIGSE a command to exert a pressure pulse cause.
  • a pressure pulse control unit DIGSE a command to exert a pressure pulse cause.
  • the pressure pulse control unit DIGSE controls the pressure pulse generator so that at a precisely defined time, e.g. B. exactly 500 ms after receipt of the command, on the axis or immediately on the Rail a pressure pulse is triggered.
  • the DIS pressure pulse sensor registers all those spreading in the rail Structure-borne sound waves and feeds the measurement signals to a sensor control unit SSE.
  • the background noise which especially during the movement of the vehicle can be significant, the unreflected Pressure pulse and those reflected by the axes of the vehicle association Pressure pulses superimposed. Part of the background noise is initially removed from the measurement signal by suitable filters in the sensor control unit. The remaining signal protrudes from the unreflected pressure pulse originating signal portion clearly out. If, as shown in Fig. 1, Pressure pulse generator DIG and pressure pulse sensor directly adjacent this signal component can be recognized in addition to its size also by that after exerting the pressure pulse first, d. H. before arrival of the reflected pressure pulses, is registered by the pressure pulse sensor DIS.
  • This unreflected signal component is fed to a pulse shape memory PFS and saved there. Henceforth it serves as a reference signal, which in one Cross-correlator KK is cross-correlated with the rest of the signal curve. On in this way, the relatively weak reflected pressure pulses can be filter out of background noise with sufficient reliability.
  • the cross-correlator KK delivers a sequence of times at its output, for which the pressure pulse sensor DIS has registered a pressure pulse.
  • Each pressure pulse corresponds to an axis of the vehicle association and is therefore counted by the central processing unit CPU. Axes from further removed vehicle groups are due to the too low signal / noise ratio no longer registered. The same applies to multiply reflected Pressure pulses.
  • the evaluation device AUSW preferably has a memory SP, before the determination of the actual number of axles just described Target number of axles of the vehicle association has been supplied.
  • the central processing unit The CPU then compares this number of target axes with the actual one Number of axes and performs an alarm action in the event of a deviation.
  • a such an alarm action can, as already mentioned above, in an acoustic There is a warning to the driver.
  • the alarm action is shown in Fig. 2 identified by the reference symbol AL.
  • pressure pulse sensor DIS another pressure pulse sensor is provided.
  • One of the measurement signals originating from these two pressure pulse sensors is delayed in a delay element and with the undelayed Measuring signal correlated. In this way you can register the weak further improve reflected pressure pulses.
  • the pressure pulse generator DIG is not only one, but several pressure pulses in close succession or in a characteristic temporal pattern on the rail. Also the reflected pressure pulses then hit in this sequence or in this temporal Pattern on the pressure pulse sensor. In this way, reliability can be the axle count further increased.
  • the last received reflected pressure pulse comes from a vehicle at the end of the vehicle association.
  • the timespan between the application of the pressure pulse generated by the pressure pulse generator DIG and the arrival of the last arriving pressure pulse results in Multiplication by the speed of sound in the rail twice the length of the vehicle association. It is assumed that the in the previous Sections described devices themselves in a vehicle at one end of the vehicle association, e.g. B. the TFZ locomotive.
  • the length of the vehicle association is used in many modern signal systems is needed and is particularly important for freight trains with their many individual ones Vehicles of different lengths cannot be easily determined in another way.
  • the invention is not based on the use of only one rail is limited. Not least for reasons of availability, it will be preferable be a separate pressure pulse sensor for each rail and possibly also one to provide your own pressure pulse generator. Then two sensor signals are available Available that can be correlated with each other if necessary.
