Definitions

  • the invention relates to a method for determining a current location information of a vehicle, which may be in an operating state and in a parking state.
  • the invention also relates to a method for resuming a monitored operating state of a vehicle to be monitored by an electronic control system, in particular of a rail vehicle, wherein the electronic control system is provided with up-to-date location information relating to the vehicle to be monitored.
  • an electronic control system in particular of a rail vehicle, wherein the electronic control system is provided with up-to-date location information relating to the vehicle to be monitored.
  • rail vehicles such as trains or a single traction unit
  • ETCS central electronic control system
  • Similar electronic control systems are also known for other vehicles, eg automatic loading systems in container ports.
  • the vehicle In order to be monitored and controlled by the electronic control system (monitored operating state), the vehicle must be logged in (logged in) in the electronic control system.
  • the vehicles controlled by an electronic control system are generally not in operation all the time, but are used on various occasions, e.g. overnight, parked.
  • the vehicle is switched off (park state - NP (no power)) and thus logged out of the electronic control system (deregistered).
  • the vehicle To return to a monitored operating state, the vehicle must be logged again in the control system.
  • it is particularly necessary to transmit current information regarding the current position of the vehicle (current location information) to the control system.
  • the electronic control system must be extremely secure in coordinating traffic, as errors can lead to collisions of trains that could potentially injure people. Therefore, the information about the rolling stock, which are in operation in the transport network, in particular the current location information, also must be highly secure.
  • the position of the vehicle In order to obtain a reliable location information, therefore, the position of the vehicle must first be determined, for example by means of GPS or by passing a position marker (day, balise, ..). Logging a vehicle into an electronic control system is therefore complex and requires time during which the vehicle is only in a limited-speed mode and limited vehicle monitoring can be operated. This in turn allows only a small vehicle density on the corresponding sections.
  • ETCS Level 2 provides a simplified login procedure if movement since the last logout can be excluded.
  • EP 2 502 800 A1 discloses a method in which a switching device is provided with holding portions and non-holding portions. When the vehicle is moving, a magnetic display element is brought from a portion of a holding portion in which the display element is held due to the magnetic attraction force in a range of non-holding portion and changes its position due to gravity. This in EP 2 502 800 A1 Although described method requires no power, but the device that is required for this is very complex mechanically, especially when a high level of safety (SIL4) is to be achieved.
  • SIL4 high level of safety
  • This object is achieved by a method for determining a current location information according to claim 1, a method for resuming a monitored operating state of a to be monitored by an electronic control system vehicle according to claim 2 and a security system according to claim 8.
  • the vehicle In operation, the vehicle is powered so that it can log in to an electronic control system to be placed in an operating state monitored by the electronic control system.
  • the vehicle When parked, the vehicle is not supplied with power (park state).
  • Reliable location information can be determined before the transition to the park state, for example by GPS positioning and / or by passing over beacons. This information is stored in a storage device.
  • the remaining image is (after resumption of the operating state) with unchanged setting of the imaging device (same position in / on the vehicle, same orientation as when recording the first image before leaving the Operating state), so that - provided that the vehicle has not moved - in both cases, the same environment section is displayed.
  • a portion of the environment is selected as the surrounding portion, which contains at least one immovable part (reference object), so that even in windy weather, for example, no changes with respect to the reference object, which could falsely indicate a movement of the vehicle.
  • the two images are compared by means of the comparison device with each other.
  • a match is given in particular if a previously defined reference pattern / reference topology has identical characteristics (surfaces, edges, objects, surface texture, etc.) on both images.
  • the invention also relates to a method for resuming a monitored operating state of a vehicle to be monitored by an electronic control system.
  • the current location information that is made available to the electronic control system in order to put the vehicle in the monitored operating state (ie for logging into the electronic control system), determined by means of the method described above.
  • the vehicle In the monitored operating state, the vehicle is registered in the central electronic system and is monitored and / or controlled by the latter. If the vehicle is in a non-safety-monitored operating state and is moved (of its own accord or else also dragged or pushed), the method described above makes it possible to detect and detect such movements (cold movements) (in the unmonitored operating state).
  • the vehicle is (after resumption of the operating state) without further localization with the last determined in the monitored state location information in the monitored by the electronic control system state, if the comparison shows that the other Picture matches the first picture. Since a cold movement of the vehicle can be excluded by the image comparison according to the invention, the location information determined last in the monitored operating mode (and stored in the control system) can be used as the current location information for logging into the electronic control system. The logging into the electronic control system can thus be done very quickly, so that within a short time a large vehicle views on the corresponding sections can be realized.
  • the vehicle is operating in a restricted mode of operation if the comparison indicates that the further image does not match the first image.
  • the vehicle can only be moved at limited speed and with limited safety monitoring, as long as there is secure location information with respect to the vehicle, e.g. by crossing a position marker (day, balise, ..). Only then is it possible to log into the automatic control system. This ensures that the vehicle can be braked manually if necessary.
  • the vehicle is a track-bound vehicle, in particular a rail vehicle, for example a train or a locomotive for a train.
  • a rail vehicle for example a train or a locomotive for a train.
  • the method according to the invention can also be used with other autonomously operated vehicles (for example automatic loading systems in container ports).
  • the illustrated surrounding section preferably comprises a part of a track bed. Since the track bed does not change within a deactivation period of a train, it is suitable as a reference object to assess whether a cold movement of the train has taken place.
  • the automatic control system is ETCS.
  • the invention also relates to a security system with a vehicle, in particular a rail vehicle, with a vehicle-mounted imaging Device, a memory device and a comparison device which is adapted to compare images generated by the imaging device with each other and with an electronic control system, in particular ETCS, wherein the comparison device is connected to the electronic control system.
  • a security system with a vehicle, in particular a rail vehicle, with a vehicle-mounted imaging Device, a memory device and a comparison device which is adapted to compare images generated by the imaging device with each other and with an electronic control system, in particular ETCS, wherein the comparison device is connected to the electronic control system.
  • the security system according to the invention is preferably set up to carry out the method described above.
  • the imaging device with each of which an image of the surrounding portion is taken before leaving the operating state and after resuming the operating state, may be mounted inside or outside the vehicle. It is crucial that the imaging device is oriented so that an image of a section of the environment in which the vehicle is located, can be generated.
  • the comparison device is set up to define a reference object and to perform an image comparison based on the reference object.
  • the imaging device comprises a camera. This embodiment is suitable for comparing 2D images with each other.
  • the imaging device may comprise a 3D scanning device, in particular a laser scanner, an ultrasound scanner, an X-ray scanner, or a radar scanner.
  • a 3D scanning device in particular a laser scanner, an ultrasound scanner, an X-ray scanner, or a radar scanner.
  • the topology of the environment can be included.
  • a vehicle 1 controlled by an electronic control system may be in an operating state in which it is supplied with power and in a park state in which it is not supplied with power. If the vehicle is in the operating state, it can be brought into an operating state monitored by the electronic control system 7 by logging into an electronic control system 7 .
  • the electronic control system 7 In order to transfer the vehicle 1 to the monitored operating state, the electronic control system 7 requires current location information relating to the vehicle 1 (indication of where the vehicle 1 is located). Before the first log-on into the electronic control system 7, this current location information (start location information) must first be determined, e.g. by crossing a balise or by GPS). While the vehicle 1 is in the monitored operating state, location information is repeatedly determined in order to enable secure control of the vehicle, with the location information determined last in each case representing the current location information.
  • start location information e.g. by crossing a balise or by GPS
  • the method according to the invention relates to a method for simplified / accelerated resumption of the monitored operating state of the vehicle 1 by the electronic control system 7 after the vehicle 1 has meanwhile logged out of the electronic control system 7 and been in the parking state.
  • Fig. 1 shows the essential steps of the method according to the invention.
  • a first recording time t1 of a mounted on the vehicle 1 imaging device 2 a first image of the environment in which the vehicle 1 is located and stored in a memory device 3 .
  • the valid for the first recording time t1 location information I1 is stored.
  • the imaging device 2 After resumption of the (initially unmonitored) operating state (Start of Mission) is taken by the imaging device 2 at a second recording time t2 another image with the same orientation of the imaging device 2 relative to the vehicle 1.
  • Both images are provided to a comparison device 4 , which compares the two images with one another and transmits the comparison result to a control device 5 , for example to an ETCS vehicle computer (European Vital Computer) of the electronic control system 7, in which also preferably the one for the first recording time t1 valid location information I1 is stored.
  • the controller 5 may include the memory device 3 (not shown). If the result of the comparison indicates that the vehicle 1 has not moved in the time between the recordings of the two pictures, the control device 5 logs the vehicle at a central device 6 of the electronic control system 7, eg a line center, by transmitting the data at the first recording time t1 current location information I1, and thus brings the vehicle 1 in the monitored operating condition. The valid for the first recording time t1 current location information I1 is therefore transmitted to the control system as current location information.
  • the vehicle is initially operated in a restricted (unmonitored) operating state and the vehicle's position is redetermined as soon as possible (current location information).
  • Fig. 2 shows an embodiment of a security system according to the invention, in which the storage device 3 and comparison device 4 are in the vehicle 1. This has the advantage that the evaluation of the image data can be carried out directly on site.
  • the comparison device is in the examples shown ( Fig.2, Fig. 3 ) is shown outside the electronic control system 7, but may also be part of the electronic control system 7.
  • Fig. 3 shows an embodiment in which the memory device 3 is integrated in the comparator 4.
  • Memory device 3 and comparator 4 thus here forms a functional building block.
  • storage device 3 and comparison device 4 are arranged outside the vehicle and can therefore be used as a central storage / comparison device which processes the data from a plurality of vehicles.
  • the camera is at the in Fig. 3 shown embodiment disposed within the vehicle. In this case, however, it must be ensured that the camera is aligned (if necessary by means of optical elements) in such a way that it can image an environmental section.
