Definitions

  • the invention relates to a high-speed train with a system for obstacle warning in track-guided traffic.
  • prophylactic measures such as e.g. the establishment of barriers and other access restrictions realized.
  • the remaining risk after such measures could be further reduced if it were possible to recognize potentially dangerous obstacles in time.
  • the respective endangered vehicle could be brought to a halt in time for the obstacle, or trips on the affected track could be prevented until the obstacle was safely removed.
  • US Pat. No. 6,417,765 proposes a track-bound sensor carrier which precedes the track-bound vehicle at a sufficient distance, and thus can warn the vehicle in good time of possible obstacles. Such a system is also associated with high technical complexity.
  • the high-speed train according to the invention comprises at least one sensor arranged on the high-speed train, the sensor being aligned on the pathway adjacent to the travel path of the high-speed train, so that potential Obstacles can be detected within the clearance gauge of the adjacent path.
  • the high-speed train according to the invention therefore does not detect the obstacles immediately ahead of the high-speed train, but those which are located on the adjacent travel route. Since the railway lines of modern railway systems comprise at least two routes, the invention is generally applicable.
  • the obstacle information obtained can be forwarded to an operations center indicating the location of the obstacle. This allows the targeted blocking of the affected section of track and the targeted (time-saving) use of clearing and maintenance services.
  • a prevention or a cancellation of the ride on the neighboring path can be done. With sufficiently reliable automatic classification of the obstacle, this can also be done automatically. This requires a connection to the operations control system. This leads to a relief of the operation as well as independence from the human reaction time and error severity.
  • a high-resolution imaging sensor system and a fast processing of the resulting data is advantageously used.
  • the sensor may in particular be an optical sensor, e.g. an IR sensor or a radar sensor.
  • the transfer of the image to the operations center could be used to assess the obstacle and determine appropriate measures by humans.
  • a particularly advantageous embodiment of the high-speed train according to the invention is the arrangement of a respective sensor at the beginning of the train and a sensor at the train end. It can be assumed that "harmless" objects which, although alarming due to their size but which, by their very nature, do not present a danger, are thrown off the track by the airstream, i. be removed. By correlating the sensor information at the beginning of the train with the respective sensor information at the end of the train, it can be ascertained whether an object is still present in the observation area at the same location after the train has traveled past. If this is the case, it can be assumed in the first approximation that it is an object with potential dangers.
  • the interaction of different sensors may be required to increase the probability of detection or to reduce the false alarm rate; e.g. the combination of optical sensors (e.g., infrared sensors) with radar sensors.
  • optical sensors e.g., infrared sensors
  • Fig. 1 shows a high-speed train according to the invention with a system for obstacle warning.
  • the track-bound / high-speed train Fz for example a maglev, moves along lane A.
  • a sensor S1, S1 is respectively aligned whose viewing direction is oriented transversely to the direction of travel of the vehicle Fz, so that obstacles can be detected on the adjacent lane B.
  • the angle between the direction of travel of the high-speed train Fz and the viewing direction of the sensors is selected to be approximately 90 °. It should be noted, however, that in the context of the present invention, other angles can be selected (eg with a deviation from the exact transverse direction by ⁇ 30 °), as long as it can be ensured that the sensors still cover the gauge of the adjacent track B.
  • track-guided systems are basically direction independent, i. can be used in both directions, there is another - not shown - embodiment is to mount the required sensors with appropriate evaluation electronics in both transverse directions on the vehicle Fz.
  • FIG. 1 A possible structure for the associated evaluation circuit is shown in FIG.
  • the sensor data of the two sensors S1, S1 (FIG. 1) are first fed separately to a signal / image processing unit S / B1, S / B2.
  • a correlation / image comparison of the sensor data of sensor S1 and S2 then takes place.
  • the sensor data of one of the two sensors must first be subjected to a time delay (delay unit DT) which is proportional to the quotient of the distance of the mounted sensors S1, S1 in the high-speed train Fz and the measured speed v.
  • delay unit DT time delay
  • a comparison of the sensor data is then carried out with a predetermined threshold, wherein an alarm message is output when exceeded.
