Definitions

  • the invention relates to a method for monitoring the stability of a moving object, in particular a rail vehicle, with respect to a fixed base and to a device for carrying out the method in a rail vehicle.
  • the following description refers essentially to the standstill monitoring in rail vehicles, without the invention being limited to this particular application.
  • the invention can be used for standstill detection and monitoring in any relative movement, for example in industrial manufacturing processes or vehicles of all kinds.
  • Modern train control devices require accurate location or location information of both parked and moving rail vehicles.
  • Conventional train control systems are increasingly supplemented or superseded by radio-based train control systems.
  • radio-based train control systems such as ETCS - European Train Control System - Level 2
  • driving licenses are determined in a trackside control center and transmitted to the individual rail vehicles by radio.
  • the driving permit contains, among other information, the speed profile of the route and the distance between the current position and the next monitored stopping place.
  • a vehicle device determines the distance covered and prevents the permissible speed from being exceeded by timely automatic activation of the brake. speed and passing the monitored
  • Stop location A prerequisite for the safe functioning of these train control systems is that the actual current position of the rail vehicle is known in the track-side control center, so that the distance can be calculated to the stop for the to be transmitted driving license.
  • the vehicle position is determined by way of reference points on the track, for example locating beacons.
  • a path measuring device of the vehicle continuously determines the relative position of the vehicle to the
  • the fuse-technical position of the vehicle is not known and the initialization of the vehicle position can be determined only by driving over at least two location reference points, for example, balises. Only then can the vehicle be put into operation from the train control point of view. This means that vehicles in parking positions may not be switched off completely; at least the train control must remain active. The disadvantage is above all the considerable energy requirement required for this purpose.
  • the rail vehicle stores its fuse-technical position before switching off and this position is used after restarting as initialization position.
  • Necessary fuse-technical prerequisite for the usability of the stored vehicle position is that the vehicle was not moved when the vehicle device is switched off - Cold Movement Detection - CMD.
  • movement of the rail vehicle occurs, for example by towing, rolling on a slope or feed due to maneuvering, the use of the original position for initialization purposes by personnel must be prevented. This non-technical solution is often not feasible in reality.
  • GPS - Global Position System - it would be possible to use the GPS - Global Position System - to determine the parking place before switching off the vehicle device and store retentive and after switching on the current location to determine and compare with the stored location.
  • the problem with this is that a sufficient number of storage locations do not provide a sufficiently strong satellite signal, for example in maintenance halls and covered or underground stations.
  • the invention is accordingly based on the object, a method and a device for standstill monitoring a moving object, in particular a rail vehicle, specify that enable a current-less switching of the moving object during the standstill phase, wherein the Device for standstill monitoring no external power supply needs.
  • the object is achieved in that at standstill no movement-induced increase in a rolling - length of a free end of a Abrollseiles is determined, the free end is kept loose in a vertical orientation between the movable object and the solid ground.
  • the object is achieved according to claim 2 for a rail vehicle by a device in which a roller on which the unwinding rope is wound on the rail vehicle is arranged perpendicularly over a rail, wherein at the free end of the Abrollseiles a permanent magnet is attached, the magnetic Holding force on the rail is dimensioned such that upon movement of the rail vehicle results in an increase in the rolling length of the free end of the Abrollseiles.
  • the Abrollseil, at the free end of the permanent magnet is fixed, lowered so far until the permanent magnet is directly above the rail.
  • the roller is fixed at the bottom of the car body at a vertical distance above the rail. If the permanent magnet contacts the rail, the roller has been rotated by a certain angle of rotation or a certain number of revolutions, whereby the unwinding length of the free end of the unwinding rope is known.
  • the role and the permanent magnet are due to gravity vertically opposite.
  • the role contains even more Abrollseil that can only be unwound from the role when the rail vehicle is moved, since the magnetic holding force of the permanent magnet quasi holds the free end of the Abrollseiles on the rail and only in vehicle movement an inclination of the Abrollseiles, that is one Increasing the rolling length of the free end, causes.
  • the free end of the Abrollseiles is rolled up again on the roll and determines the Abrollin by counting the revolutions or finding a rotation angle. If the rolling length is greater than at the time of the shutdown of the rail vehicle, a movement of the rail vehicle has taken place in the meantime. An external power supply of this device for standstill monitoring is not required.
  • the determination of whether the unwinding length of the free end of the Abrollseiles has extended in the stoppage phase of the rail vehicle is carried out according to claim 4 preferably characterized in that electronic means for detecting and storing a rotational movement of the roller are provided.
  • the rotational movement can be detected, for example, with an electronic revolution sensor whose output signal acts on an electronic read-only memory, in particular an EEPROM. A manual determination of the Abrollin is therefore no longer necessary.
  • FIG. 1 shows a device for detecting a movement
  • Figure 2 shows the device according to Figure 1 with detected movement.
  • the device consists essentially of a roller 1, which is attached to the underside of a car body 2 of a rail vehicle and on which a highly flexible wire 3 is guided as Abrollseil.
  • a permanent magnet 4 is attached, which hangs in the raw state of the rail vehicle perpendicular to a rail 5, wherein between see permanent magnet 4 and rail 5, a magnetic force acts. If, as required, the rail vehicle has not been moved in the parked state, the free end of the wire 3 with the permanent magnets 4 remains hanging vertically in a constant length between the roller 1 and the rail 5, as FIG. 1 shows.
  • the wire 3 is unrolled on the roller 1 by a certain order, whereby the free end of the wire 3 extends between the roller 1 and the rail 5.
  • This movement process is shown in FIG.
  • the permanent magnet 4 pulls on the wire end until the wire 3 is completely unrolled on the roll 1.
  • the holding force of the permanent magnet 4 on the rail 5 is dimensioned such that the rolling resistance of the wire 3 on the roller 1 is overcome with certainty when the rail vehicle 6 is moved. If the entire wire 3 unwound and the rail vehicle is still further moved, the wire 3 depends on the direction of travel in a certain oblique position to the bottom right or bottom left and is pulled along with the permanent magnet 4 on the rail 5.
  • the sketched device allows a standstill or motion detection without own energy needs. In the standstill position, the rail vehicle can thus be completely de-energized, including the vehicle device usually required for standstill monitoring.

Abstract

L'invention concerne un procédé de surveillance de l'arrêt d'un objet mobile, en particulier d'un véhicule ferroviaire, par rapport à une base fixe, ainsi qu'un dispositif pour la mise en œuvre de ce procédé sur un véhicule ferroviaire. Le but de l'invention est de permettre de constater de manière fiable le respect de l'arrêt sans consommation d'énergie. À cet effet, selon ledit procédé, lorsque le véhicule est à l'arrêt, aucun agrandissement, dû au mouvement, d'une longueur de déroulement d'une extrémité libre d'un câble déroulable n'est constaté, l'extrémité libre étant maintenue lâche magnétiquement en position verticale entre l'objet mobile et la base fixe.
