Definitions

  • the invention relates generally to a method for assigning a rail vehicle to a warning area of a track construction site and to a warning system with which an automated allocation of a rail vehicle to a warning area can take place.
  • Such warning systems for track construction sites usually have a plurality of boundary markings which divide a track section into sections dividing warning areas, a detection device which detects the boundary markings and at least one warning emitter emitting a warning transmitter being provided on a rail vehicle on the track section.
  • the rail vehicle is assigned to the warning area by detection of the boundary markings arranged on the track section, into which the rail vehicle enters, with a warning - as is generally known - for example by means of train detectors installed on the side track.
  • the target value for the number of hazardous failures of the safety-related function should be about 10 -8 h -1 to 10 -7 h -1 or less.
  • the object of the invention is therefore to provide a method for automatically allocating a rail vehicle to a warning area and a warning system for a track construction site, which enable a highly secure automated range conversion between warning areas installed in the track construction site.
  • the basic idea of the invention is to bring about a high standard of security in the automatic warning range change by using two redundant and diverse methods for detecting a reference point and / or a boundary marking.
  • a certain preset tolerance can be provided, which allows the automatic switching even within predetermined tolerance limits, if the reference point is not detected simultaneously by both navigation satellite systems or the detected boundary mark is not identical to the detected reference point.
  • the tolerance limits can, for example, be measured in the time domain in seconds or in the case of spatial deviations in meters.
  • the tolerance may also be dependent on the speed of the rail vehicle: at higher speeds, the tolerance limits - at least in the time domain - should be narrow, but at low speeds, the tolerance may be rather generous.
  • the tolerance limits are to be dimensioned in advance so that a distinction can be made between two warning areas.
  • an alarm is output and the rail vehicle is preferably stopped. If both systems fail, an alarm and possibly a warning signal will have to be output anyway.
  • the alarm is directed in particular to the vehicle driver of the rail vehicle, the warning signal (usually) being used to warn passengers of trains passing in the neighboring track.
  • the warning system provides a simple redundant system, in which the direction of travel of the rail vehicle can be derived without consuming technology from the surfaces of the boundary marking bearing different symbols for the directed optical recognition.
  • the symbols for each direction of travel are clearly defined, so that from the symbol both the direction of travel and the respective warning range in which the rail vehicle enters, can be derived.
  • the invention thus provides a method for allocating a rail vehicle to a warning area when entering the warning area with the following steps: subdividing a track section into at least one subsection dividing the track section into a warning area, determining the coordinates of Partial section boundaries as reference points, determining the position of the rail vehicle by means of a first global navigation satellite system and a second global navigation satellite system different from the first global navigation satellite system, determining the direction of travel of the rail vehicle, assigning the rail vehicle to a direction in the direction of warning warning area upon detection of a reference point by means of the first global navigation satellite system and the second global navigation satellite system or outputting an alarm upon detection of the reference point with only one global navigation satellite system.
  • a method for assigning a rail vehicle to a warning area when entering the warning area comprising the steps of: subdividing a track section into at least one subsection dividing the track section into a warning area (20a, 20b), determining the coordinates of the subsection boundaries as reference points, marking the reference points as boundary marks arranged on the track section, determining the position of the rail vehicle by means of at least one global navigation satellite system, determining the direction of travel of the rail vehicle, assigning the rail vehicle to an in-direction warning area upon detection of the reference point by means of the one global navigation satellite system and detecting the boundary marking or outputting a Alarm if there is no detection of at least the reference point or the boundary marking.
  • the rail vehicle will be a track-laying machine.
  • other types of rail vehicles are usable for the application of the method or in the context of the warning system.
  • the at least one global navigation satellite system is preferably selected from the group consisting of NAVSTAR GPS, GLONASS, Galileo and Beidou.
  • boundary markings on the track at the reference point are objects to be installed that mark the boundaries of a warning area.
  • the boundary markers can therefore represent or carry an optical symbol or be designed as a transmitter.
  • the use of a transmitter set up as a transponder is proposed.
  • the transponder is an RFID chip and the receiver corresponding to an RFID reader.
  • Other data transmission standards such as e.g. Bluetooth, Wi-Fi, ZigBee, NFC, Wibree or WiMAX are also possible.
  • a warning system for a track construction site with a plurality of boundary markings for the establishment of a track section in warning subdividing subsections, a boundary detecting detection device for attachment to a running on the track section rail vehicle, and at least one emitting a warning signal warning transmitter, said Boundary markers and the detection means comprise means for forming a radio link between the boundary marking and the detection means and for the optical detection of the boundary marking by the detection means and wherein the boundary marks each have two opposite, for the directional optical detection different symbols bearing surfaces for detecting the direction of travel of the rail vehicle ,
  • the warning transmitter is designed as an optical and / or acoustic warning transmitter, wherein the warning signal is an optical and / or acoustic signal.
  • the border marking preferably has at least one transmitter emitting an identifier and the detection device has a receiver which detects the identifier of the at least one transmitter.
  • the boundary markers can each radiate different identifiers, so that an individual identifier can be assigned to a specific boundary marking and thus to the transition between two warning areas.
  • the transmitter is designed as a transponder.
  • the transponder is an RFID chip and the receiver is an RFID reader.
  • Other data transmission standards such as e.g. Bluetooth, Wi-Fi, ZigBee, NFC, Wibree or WiMAX are also possible.
  • the detection device has a camera detecting the boundary markings.
  • the identification of the border marking can be made, for example, by the shape of the border marking or a symbol attached to the border marking.
  • the detection means may be a radar recognizing the boundary marks.
  • Fig. 1 shows a schematic view of an established with the system according to the invention track construction site.
  • the track construction site 100 has a track section 20 on which a rail vehicle 40, in particular a track construction machine, is arranged.
  • the track workers are in particular endangered by trains passing by on the track section 20 next to each other, in front of which the warning system warns in advance in sufficient time.
  • the track construction site 100 or the track section 20 is subdivided by the boundary markings 10 into a plurality of subsections, which are designated and treated as warning areas 20a, 20b.
  • a detection device 30 detecting the boundary markings 10 is provided on the rail vehicle 40.
  • the boundary markers 10 and the detection device 30 have means for forming a radio link between the boundary marking 10 and the detection device 30 and for the optical recognition of the boundary marking 10 by the detection device 30.
  • each border marking 10 is equipped with an RFID chip, in particular an RFID transponder, which is detected by the detection device 30.
  • the boundary marks 10 have a special shape or wear certain symbols.
  • the boundary markers 10 may have two opposing surfaces that carry different symbols - by the directed optical detection, for example by means of a camera, the direction of travel of the rail vehicle 40 can be readily recognized. In particular, in the latter case, when optically detecting the symbol, it is clear which warning area 20a, 20b leaves the rail vehicle 40 or enters it.
  • the automatic range switching is always performed only when the detection device 30 has both established the radio connection with the boundary marking 10 and the boundary marking 10 has also detected optically.
  • each boundary marker 10 receives a unique radio identifier and a unique optical identifier whose characteristics are stored for each boundary marker 10 together in a database.
  • the detection device 30 supplies the detected radio identifier and the detected optical identifier to a comparator accessing the database, which can only cause the range switchover if the detected identifiers match the stored identifiers.
  • the database can be protected against unauthorized access encrypted stored.
  • a plausibility check of the detected identifiers in connection with the direction of travel derived therefrom and / or a GPS signal transmitted by the border marking and / or the rail vehicle can also take place.
