Definitions

  • the two mobile radio devices of an on-board unit are only used in parallel for a small part of the ETCS operating time, namely during the neighboring control center transition.
  • ETCS electronic circuitry
  • one or possibly both ETCS mobile radio devices or their antennas could be used for other services.
  • ETCS requests mobile devices they must be made available to ETCS again immediately.
  • the quality of mobile communication also known as "Quality of Service"
  • ETCS roof antennas and their feed lines must meet a number of requirements that limit the structure and placement of the antennas on the roof. Various electrical and mechanical requirements as well as minimum distances between the antennas must be observed. This limits the possible number of cellular antennas on the rail vehicles. If, in addition to the ETCS mobile radio antennas, additional antennas are to be retrofitted on the roof of a rail vehicle, space problems often arise or technically complex solutions are necessary.
  • ERTMS European Rail Traffic Management System
  • voice service train radio via which the vehicle driver can communicate with the responsible dispatcher using rail-specific extensions to the GSM mobile radio standard (location dependent addressing).
  • the DE 103 19 904 A1 discloses a method for operating an ETCS mobile radio antenna arrangement in an on board unit which is installed in an ETCS rail vehicle. There is also an ETCS mobile radio antenna and an ETCS mobile radio device, which can be connected using an ETCS antenna switch. Accordingly, there is another ETCS mobile radio antenna on the train, and the on-board unit can optionally be connected to one or the other ETCS mobile radio antenna via the antenna switch.
  • the EP 0 573 856 A1 deals with antenna switching between different antennas. Antenna switching between an internal and an external antenna of a radio must be carried out. Switching takes place according to the criterion which antenna allows better reception quality.
  • the invention is based on the object of specifying a method for operating an ETCS mobile radio antenna arrangement with which ETCS-external rail services with mobile communication can be integrated into ETCS rail vehicles.
  • ETCS European Train Control System
  • An essential advantage of the method according to the invention is seen in the fact that different services, namely ETCS-internal and / or ETCS-external services, share the existing ETCS mobile radio antennas of the respective rail vehicle.
  • a further antenna installation on the roof of a rail vehicle can advantageously be omitted for these services. This relaxes the space problem for additional mobile radio antennas on the roof of a rail vehicle.
  • the method is simple in that a control logic is used which determines the switching position of the ETCS antenna switch from ETCS status information of an on-board unit and then controls the antenna switch accordingly; the required hardware can be structured flexibly and integrated into the rail vehicle in different ways.
  • the ETCS function remains unchanged. Neither data communication nor the ETCS protocols are affected. Influences on the ETCS system availability through the ETCS antenna switch are negligibly small if a high-quality hardware version is used.
  • Difficulties with overlapping frequency ranges can easily be avoided. It is possible to install at least one mobile radio antenna that is suitable for frequency ranges from GSM-R and UMTS or LTE. With the help of the ETCS antenna switch, a high-frequency signal from one or more ETCS roof antennas can alternatively be provided for the ETCS vehicle control or for other communication services.
  • Other communication services can be cellular devices, cellular networks and / or cellular services.
  • the special control logic can be used to decide whether the ETCS mobile radio antenna is activated for ETCS vehicle control or for other services in the vehicle. Since the control of the rail vehicle has priority at all times, the control logic must have continuous knowledge of whether the ETCS mobile radio antenna is required for ETCS or not. As soon as ETCS has a communication requirement for the switchable antenna, this is made available for ETCS according to the invention. Other services must therefore expect an interruption at any time and temporary unavailability of the mobile communication. This boundary condition must be taken into account when selecting potential other rail services. However, the transmission quality provided by the method according to the invention is sufficient for services such as ETCS key management and the transmission of ETCS diagnostic data.
  • ETCS status information can be used for the control logic in the method according to the invention. However, it has proven to be particularly advantageous if the ETCS status information is obtained from information regarding the status, occupancy and communication requirements of the mobile radio devices used in the on-board unit of the ETCS rail vehicle.
  • ETCS calls are always made while the ETCS train is traveling, so that during the time the ETCS mobile antenna is being made available for other rail services, there is no communication problem with regard to unsuccessful connection requests from the route center.
  • a non-safety-related preprocessing computer and a signal-technically safe computer are used. It is advantageous to obtain the ETCS status information from the control logic using the non-safety-related preprocessing computer of the on-board unit of the ETCS rail vehicle.
  • control logic can advantageously be integrated into the CPU of the non-security-relevant preprocessing computer.
  • control logic it is also possible to house the control logic in a special component, for example in a microcontroller.
  • the ETCS status information is obtained by means of a separate computer module comprising the control logic, which also contains the ETCS antenna switch.
  • the module thus formed can be integrated as a module in the non-safety-related preprocessing computer and enables simple data transfer between the CPU of the non-safety-related preprocessing computer and the periphery of the non-safety-related preprocessing computer with regard to the ETCS status information or the control signal for the ETCS antenna switch.
  • the ETCS antenna switch is arranged on an external module and by means of a wire-bound interface with the non-safety-related preprocessing computer is connected, i.e. is not integrated into the non-safety-related preprocessing computer.
  • the control signal for the ETCS antenna switch or the ETCS status information can be transmitted via this interface.
  • a module for the control logic on the external module is required here, and a power supply is also required for the external module.
  • control logic uses ETCS-internal status and diagnostic information when forming switching commands for the antenna switch.
  • an antenna signal switch is integrated in the antenna path between the ETCS antenna switch and the further mobile radio device. If the antenna signal switch is an active antenna signal switch, then the ETCS mobile radio device is also supplied with an antenna voltage when the ETCS antenna switch has released the ETCS mobile radio antenna for other services. When using a passive antenna signal switch, the antenna signal is reduced by about 3 dB, which slightly reduces the quality for the other rail services, but there is the advantage that the ETCS mobile device remains logged in to the GSM-R network and the GSM-R Cell forwarding continues. This means that a connection can be established without delay after the ETCS cellular antenna is switched back to ETCS.
  • location information of the ETCS train vehicle is taken into account by the control logic.
  • the control for releasing the switchable antenna for other services also depends on how quickly an ETCS mobile device logs back into the GSM-R network after the antenna is available again for ETCS.
  • further information for the switchover logic can be consulted, by means of which the antenna switchover for ETCS takes place at a time before the ETCS connection is requested. Above all, location information can be used.
  • the invention also has the object of specifying an ETCS rail vehicle with an ETCS mobile radio antenna arrangement, with which ETCS external rail services with mobile communication can be integrated into ETCS rail vehicles.
  • an ETCS rail vehicle with an ETCS mobile radio antenna arrangement in the on-board unit is used to achieve this object.
  • a non-safety-related preprocessing computer known per se is used in the on-board unit in order to obtain the ETCS status information, the control logic being able to be arranged in different ways. It can be advantageous to integrate the control logic into the non-safety-related preprocessing computer.
  • the separate computer module can be assigned as a module to the non-safety-related preprocessing computer.
  • the ETCS antenna switch on an external module and connect it to the non-safety-related preprocessing computer by means of a wire-bound interface connect.
  • an antenna signal switch can advantageously be arranged in the antenna path between the ETCS antenna switch and the further mobile radio device, which can be a passive antenna signal switch.
  • Figure 1 shows an on-board unit 1 of an ETCS rail vehicle, not shown, which is equipped in a known manner with a signal-safe computer 2 and a non-safety-related preprocessing computer 3.
  • an ETCS mobile radio device 4 is connected to the non-safety-relevant preprocessing computer 3 and, on the other hand, another ETCS mobile radio device 5.
  • the two ETCS mobile radio devices 4 and 5 are generally used to ensure the function of both ETCS mobile radio devices in an overlap area.
  • ETCS mobile radio device 4 is connected to an ETCS antenna 6, while the further ETCS mobile radio device 5 is connected to a further ETCS mobile radio antenna 8 via an ETCS antenna switch 7. It also runs between the non-safety-related preprocessing computer 3 and the ETCS antenna switch 7 a connecting line 10, via which the switching position of the ETCS antenna switch 7 is determined by the non-safety-related preprocessing computer 3; In addition, the ETCS antenna switch 7 is actuated by the non-security-related preprocessing computer 3 via the connecting line 10.
  • the ETCS status information consists of information regarding the status, occupancy and communication requirements of the mobile radio devices used in the on-board unit 1 of the ETCS rail vehicle.
  • the state of the GSM-R mobile radio devices is determined, the number of communication options currently used and current connection requests as they exist to the route center and from the route center.
  • the control logic of the ETCS antenna switch 7 decides whether an ETCS mobile radio antenna is currently required or not. If the former is the case, then 7 messages are transmitted or received via the further ETCS mobile radio antenna. Otherwise, the message channel 13 to other non-ETCS mobile radio devices is opened or services are set up in another switching position of the ETCS antenna switch 7.
  • FIG. 2 A part of an ETCS rail vehicle 20 with an on-board unit 21 is shown.
  • a GSM-R mobile radio device 22 is connected to the on-board unit 21; a further GSM-R mobile radio device 23 is also connected to the on-board unit 21.
  • the further GSM-R mobile radio device 23 is connected to an antenna switch 25 of the on-board unit 21, the antenna switch 25 via a wired interface 26 also to the non-safety-related preprocessing computer of the on-board unit 21 for determining the switching position, which is not shown here of the antenna switch 25 and is connected to control this switch.
  • Both the one GSM-R mobile radio device 22 is connected to a GSM-R antenna 27 and the antenna switch 25 is connected to a further GSM-R antenna 28. Both antennas 27 and 28 radiate and receive messages via the closed GSM-R network and via the public UMTS / LTE network 29.
  • control logic in the non-safety-relevant preprocessing computer of the on-board unit 21 supplies the corresponding information, as described in detail above.
  • the on-board unit 21 is connected to a closed GSM-R network and a public UMTS / LTE network 29.
  • Figure 4 are elements after them Figure 1 correspond, provided with the same reference numerals. It can be seen that here an active antenna signal switch 41 is interposed in the antenna path between the ETCS antenna switch 7 and the non-ETCS mobile radio device 12, which is supplied with an antenna voltage via a connection 42.
