Definitions
- Rail vehicles track-guided vehicles with rubber tires or magnetic levitation railways
- a knowledge of the length of the respective track-bound vehicle is of fundamental importance.
- the respective vehicle length is regularly required in particular by a train control and / or train protection system used to operate the track-bound vehicles as securing technical information, which may be, for example, a CBTC (Communications-Based Train Control) system.
- CBTC Common-Based Train Control
- Such systems are widely used INS particular in transport and allow for ⁇ play, for metros and subways safe and effi ⁇ cient operation.
- the length of the respective spurge ⁇ -bound vehicle keitseinschränkungen example effects on the brake ⁇ parameter of the respective vehicle, possible velocity, control of the track-bound vehicle in question and / or that subsequent to a route other track-bound vehicle, such as part of a determination a driving license in the form of a "Movement Auhority".
- the present invention has for its object to provide a method and a device which allow determination of a length of a track-bound vehicle in automated, particularly reliable and at the same time with comparatively little effort feasible way.
- This object is achieved by a method for determining a length of a track-bound vehicle, wherein by means of a first, seen in the direction of travel front detection device of the track-bound vehicle a track-side reference point is detected by means of a two ⁇ th, seen in the direction of travel rear detection device of the track-bound vehicle, the track-side reference point is detected, a distance covered between the detection of the track-side reference point by the first detection device and the detection of the track-side reference point by the second detection device from the track-bound vehicle is determined and from the determined distance the length of the track-bound vehicle is determined.
- a distance traveled between the detection of the track-side reference point by means of the first detection device and the detection of the track-side reference point by the second detection device is determined by the track-bound vehicle.
- the determination of the distance traveled can be done in any manner known per se.
- Detecting the halnseiti ⁇ gen reference point by means of the first detection device thus serves as a "starting point” for determining Bezie ⁇ hung as measuring the distance from the track-bound vehicle path and detecting the trackside reference point by the second detecting means as the "end point" of this determination ,
- the length of the tracked vehicle is determined from the determined distance.
- the method according to the invention is advantageous since it allows an automated determination of the length of the track-bound vehicle without the need for manual inputs by an operator or a vehicle driver. In this way, a particularly reliable determination of the length of the track-bound vehicle is made possible, whereby, depending on the specific respective execution, the signal safety can be achieved, ie the high safety requirements in the field of railway signaling technology can be met.
- the length of the track-bound vehicle corresponds to the determined distance.
- the first detection device and the second detection device are each arranged essentially directly at the front or rear end of the vehicle, so that the distance between the two detection devices is equated with the length of the track-bound vehicle in the context of existing measurement inaccuracies or tolerances ⁇ the can.
- the length of the track-bound vehicle from the determined route and a first Ab ⁇ stand between the first detection device and a first, seen in the direction of travel front end of the vehicle and a second distance between the second detection device and a second, in Direction of travel seen rear end of vehicle determined.
- the distance of the detection devices to the respective vehicle end, restrictions with regard to the positioning of the detection devices are eliminated.
- They can be mounted in principle at any location or any position of the track-bound vehicle.
- the greater the distance between the first detection device and the second detection device the better will be the accuracy of the determination of the length of the track-bound vehicle as a rule.
- the first distance and the second distance may be different or identical, in which case the two detection devices are each arranged at the same distance from the respective vehicle end.
- the first distance and the second distance are respectively stored in at least one memory device of the track-bound vehicle, wherein as memory
- a vehicle-side database with data of the track-bound vehicle can be used.
- detection devices as well as track-side reference points of any type can generally be used. It is only essential here that the detection devices are suitable for detecting or detecting a reference point along the trackside. So it is for example conceivable that the vehicle side by means of detection means in the form of cameras or optical sensors shear ⁇ a trackside reference point of any type is determined.
- a specially provided for this purpose component such as in the form of a panel with an optical pattern, bar code, or a position indication in written or Zei ⁇ chenform, acts.
- the background or the surroundings of the track-bound vehicle is detected by means of the detection devices and the track-side reference point is extracted from the acquired images or image data. This can be done in such a way that artificial or natural landmarks are identified and used as a track-side reference point.
- the method according to the invention can also be developed in such a way that a balise is used as the track-side reference point and in each case a balise reader as the first and second detection device.
- a balise is used as the track-side reference point and in each case a balise reader as the first and second detection device.
- the use of a balise as a track-side reference point as well as of balise reading devices as detection devices is advantageous in that track-bound vehicles frequently already have balise reading devices for detecting or detecting track-side balises.

So-far the first detection signal containing the time of detecting the trackside reference point through the first Detekti ⁇ ons stressed and there is a temporal synchronization of the two control devices, the second control means, the distance traveled and thus ultimately borrowed and the length of the track-bound vehicle advantageous ⁇ legally determine very precisely.
- a second detection signal to the first control means is übermit ⁇ telt of the second control device to the detection of the trackside reference point by the second detection means out.
- the method according to the invention can preferably be further developed in such a way that the first detection signal contains an indication of the first distance and / or the second detection signal contains an indication of the second distance. This offers the advantage that only the first distance and / or the second control device only the second distance needs to be known to the first control device. With the respective detection signal the relevant fende distance then, if necessary, the other control device to be notified.
- the length of the track-bound vehicle is determined independently of each other by the first and the second control device. This is advantageous ⁇ way, thus eliminating the need for further communication between the first controller and the second controller is omitted for the purpose of matching or comparison of the determined length of the track-bound vehicle. So far ⁇ this is appropriate in the particular application, however, a similar comparison can be provided for verification of each particular vehicle length.
