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- Conventional train control systems are increasingly supplemented or superseded by radio-based train control systems.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-related change a rotational position of a peripheral marking of at least one rotatably mounted on the fixed base auxiliary wheel is detected, wherein the rigid Hilfsradachse is connected to the moving object.
- the object is achieved according to claim 2 for a rail vehicle by a device in which at least one
- Auxiliary wheel is connected to a peripheral marking on a rigid Hilfsradachse with the rail vehicle and at standstill of the rail vehicle in such a way rotatably mounted on a rail, that a change in the rotational position of the mark can be determined.
- the auxiliary wheel device is lowered onto the rail prior to complete disconnection of the rail vehicle, such that the auxiliary wheel makes contact with the rail and rotates upon movement of the train.
- the rotational position of the peripheral marking of the at least one auxiliary wheel is stored, in particular mechanically. If the rail vehicle is moved in the off state, the rotational position of the marking on the auxiliary wheel changes. A departure from the initial state is detected by visual inspection or electronically before the re-start of the rail vehicle by determining whether the marking still has the same rotational position. If this is the case, the rail vehicle is in the same parking position as when parking.
- a plurality of auxiliary wheels of different diameters are provided.
- the sizes of the individual Auxiliary wheels are chosen so differently that their smallest common multiple is very large. It is advantageous in the use of several, for example, three, auxiliary wheels of different diameters or circumferences in addition to greater safety in determining whether the rail vehicle was moved in the standstill phase, also the ability to determine how large the feed, that is how long the traveled distance of the rail vehicle, in fact.
- the angle of rotation of the marking of each individual auxiliary wheel is read out electrically, with each value sequence of rotational angle changes of all auxiliary wheel markings corresponding to a certain distance.
- FIG. 2 illustrates the measuring principle when using three light barriers 1.1, 1.2 and 1.3, which are assigned overlapping slots 2.1, 2.2 and 2.3 via 270 °, 180 ° and 90 ° pitch circles on an auxiliary wheel 3. This results in a maximum, despite movement of the rail vehicle
- n number of photocells 1.1, 1.2, 1.3 and
- the slots 2.1, 2.2, 2.3 may also be arranged in a separate disc, which is connected to the auxiliary wheel. 3 rotates.
- the light emitter and light receiver of the light barriers 1.1, 1.2, 1.3 are then located on both sides of the disc and the actual auxiliary wheel 3 does not have to be weakened by slots 2.1, 2.2, 2.3.
- FIG. 1 shows a device for detecting a movement
- Figure 2 is an illustration of the above-described Drehlagenfest ein by means of light barriers.
- the device sketched in FIG. 1 consists essentially of an auxiliary wheel carrier 4 which rotatably supports the auxiliary wheels 3.1, 3.2, 3.3 and which can be lowered by means of a linkage 5 when the rail vehicle 6 is stationary on a rail 7.
- the lowering process is finished when all
- Auxiliary wheels 3.1, 3.2 and 3.3 have rail contact.
- the three auxiliary wheels 3.1, 3.2 and 3.3 in the illustrated embodiment Example are hung individually on the auxiliary wheel 4, uncoupled and freely rotatable.
- the device serves the purpose of determining whether during the stoppage phase of the rail vehicle 6 yet a movement of the same has taken place.
- the three auxiliary wheels 3.1, 3.2 and 3.3 are provided with peripheral markings 8.1, 8.2 and 8.3. These markers 8.1, 8.2 and 8.3 have after lowering the auxiliary wheels 3.1, 3.2 and 3.3 on the rail 7 a very specific rotational position. This rotational position does not change when the parked rail vehicle 6 has not been properly moved during the stoppage phase. Since the three auxiliary wheels 3.1, 3.2 and 3.3 have different circumferences, for example 51 cm, 50 cm and 49 cm, the same rotational position of the auxiliary wheel markings is repeated
