Definitions
- the invention relates to a method for extending the measuring range of a measuring device with an antenna for detecting a speed and / or a path, in particular ⁇ sondere a rail vehicle over ground on the basis of the double effect, as well as a measuring device for carrying out the method.
- the following description relates essentially to the use of Doppler radar sensors in the speed and / or path determination of rail vehicles, without the invention being restricted to this particular application.
- the invention can be used for any relative movements, for example in industrial manufacturing processes or vehicles of all kinds.
- Modern train control systems require accurate He ⁇ mediation of the path and / or the speed of the trains.
- Traditional speed measuring methods are based on wheel encoders. These generate a defined number of pulses with each revolution of the wheel. The evaluation of the time intervals between these pulses leads to a keitswert VELOCITY ⁇ . Slip during starting or braking, blocking during the braking operation and a Doomed by wear ⁇ gently change the wheel circumference can, however, the measured overall speed inadequate distort. To verify the measured value and to increase the safety, the revolutions are usually driven by two possible ⁇ not be detected and braked wheels. Increasingly, one becomes the two wheel pulse generator replaced by a Doppler radar sensor.
- the position encoder has also been indispensable from a safety ⁇ technical point of view.
- the Wegimpulsgeber In addition to the detection of a very low speed or a standstill of the train, the Wegimpulsgeber also serves for Ausfalloffenba ⁇ tion of the Doppler radar sensor.
- the invention has for its object to provide a method for extending the measuring range of a measuring device of the generic type, which makes the use of an additional Wegimpulsgebers dispensable.
- the object is to modify a measuring device for carrying out the method.
- the object is achieved in that the at ⁇ antenna is set in oscillating motion and the Ge ⁇ is determined speed and / or the path by linking a gemes ⁇ Senen signal with an oscillation signal. Since the measuring device is constructed safely by signal technology can, with any failures are immediately disclosed in the measuring section, it is possible to dispense with an additional sensor, in particular Wegimpulsgeber. The accuracy of the travel / speed detection can be increased, since the above-mentioned influences, in particular by the wheel slippage ⁇ omitted. In this way, the Leis ⁇ will ultimately increase processing capacity of the train control systems.
- the oscillating movement of the antenna is preferably generated according to claim 2 mechanically, piezoelectrically, magnetoelectrically or hydraulically.
- the oscillating movement takes place preferably in the form of vibrations parallel to the direction of movement of the rail vehicle.
- the parallelism results in a simplification of the combination of the measured signal with the oscillation signal.
- the speed can be determined according to claim 4 from the difference of a measured speed and an oscillation ⁇ speed.
- the evaluation can also be based on the route information.
- the oscillation, the oscillation of the antenna that is aligned with it in the direction of movement of the rail vehicle, whereby the Messeinrich ⁇ tung measured speed and the system-specific Os ⁇ zillations für than simple scalar quantities be ⁇ can be seeks.
- the system-specific oscillation is predetermined frequency and amplitude with respect to claim 5 wherein a fixed ⁇ A position of these values or a Ü by the speed over ground-controlled adjustment provided in an order according to, wherein the response of the measuring device is exceeded. In this way, it is ensured that an evaluable total signal is generated even when the rail vehicle is stationary.
- a measuring device for carrying out the method is equipped according to claim 6 with an oscillating antenna and an evaluation device for combining the measured signal with the oscillation signal.
- the invention is based on a figurative Darge ⁇ presented embodiment explained in more detail.
- the sole figure shows the operation of the inventive SEN method for extending the measuring range of a measuring means on the basis of the ⁇ Dopplereffketes in a schematic representation.
- a vehicle F that moves at a speed v fzg over ground G.
- a Doppler antenna D is mounted, which is connected to an evaluation device A.
- the Doppler antenna D and the evaluation device A are the most essential components of the measuring device designed as a Doppler radar sensor.
- the Doppler antenna D is transformed into an oscillating motion v osc with a specific frequency and specific amplitude. puts.
- a osz v is the measured speed v measuring the oscillation drawn from ⁇ and from the vehicle speed v fzg determined over ground G.
- the measured velocity V measured results from the correlation of the k a Doppler antenna D till ⁇ radiated signal with a reflected from the ground G, received by the antenna D Doppler signal F received.
- the evaluation can also be done on the basis of the route information.
