Definitions
- the invention relates to an arrangement for transmitting a transmission signal from a transmitter to a rail vehicle located on a track section of a track for location and information transmission, in which the transmitter is connected to a line conductor fitted in the track section and having crossing points, and the rail vehicle contains a receiving unit, which receives the transmission signal and monitors the phase jumps occurring when the line conductor passes the crossing points for locating the rail vehicle.
- a reception unit is provided in or on a rail vehicle, which receives a transmission signal from a control center fed into a crossed line conductor.
- a flywheel oscillator is contained in the receiving unit, which generates a comparison signal from the received signal, which has the same frequency as the received signal and is phase-synchronized with the received signal.
- the received signal is compared with respect to its phase position with the comparison signal as soon as the received signal has fallen below a lower threshold value and then exceeded an upper threshold value; in such a case it is assumed that the received signal has passed a zero crossing in terms of amplitude and that the rail vehicle has passed a crossing point of the line conductor. If this phase comparison between the received signal and the comparison signal determines that a If the phase jump between the two signals of 180 ° has occurred, an intersection mark is generated which is used to locate the rail vehicle.
- the location computer for the LZB 80 driving devices * (E. Murr, Signal und Draht 83 (1991), 7/8, pp. 190-193) is an antenna arrangement on the rail vehicle side for the detection of line conductor crossing points on the vehicle side and thus for Locations of the rail vehicle known.
- This antenna arrangement has two antenna pairs, each of which has two individual antennas arranged at a distance of 9.90 m from one another. Driving over a crossing point can be detected on the vehicle side with either of the two antenna pairs by monitoring the output signals of the two individual antennas of the respective antenna pair for a phase jump.
- the invention has for its object to provide an arrangement with which a particularly low-interference location is possible.
- This object is achieved according to the invention in an arrangement of the type specified at the outset in that an occupancy sensor is attached to an entry point of the track section, which detects the entry of the rail vehicle into the track section and generates an occupancy signal indicating the occupancy of the track section, and that with the occupancy sensor a switching device assigned to the transmitter is connected, which controls the transmitter in such a way that it emits an unmodulated transmission signal after receipt of the occupancy signal and then a modulated transmission signal after a predetermined period of time, the predetermined period of time being dimensioned such that it is used for locating on the rail vehicle is sufficiently large.
- a major advantage of the arrangement according to the invention is that a particularly low-interference location of the rail vehicle is achieved, because when the rail vehicle enters the track section assigned to the control center - initiated by the switching device - the transmitter first generates an unmodulated transmission signal and feeds it into the line conductor becomes.
- This unmodulated transmission signal is received by the reception unit, from which it obtains a phase-synchronized comparison signal which has a particularly high quality in terms of its synchronization with the reception signal, because the transmission signal namely shortly after the rail vehicle has entered the track section - i.e. before the expiry of the predefined period of time - is still unmodulated and therefore no synchronization errors in the comparison signal due to signal molation can occur.
- the comparison signal thus has a particularly high degree of synchronization with the received signal, that is to say it is very precisely matched to the received signal with regard to its phase position, particularly precise detection of the crossing points of the line conductor and thus particularly precise location of the rail vehicle is possible.
- the specified period of time which is to be measured with regard to the time period required for locating the rail vehicle, the locating of the rail vehicle is completed and the transmission of information between the control center and the rail vehicle can begin.
- the arrangement according to the invention can be used in a very advantageous manner in the station area, since there a very exact positioning of the rail vehicle on the platform and thus a highly precise location of the rail vehicle is required.
- the information is then transmitted from the control center to the stationary rail vehicle or in the opposite direction.
- the arrangement according to the invention can be produced particularly simply and therefore inexpensively if the occupancy sensor is a rail contact or is formed by a track circuit.
- the functioning of track circuits is described, for example, in patent specification EP 0 573 131 B1.
- the invention also relates to a method for transmitting a transmission signal to a rail vehicle located on a track section of a track for location and information transmission, in which the transmitter signal is fed with a transmitter into a line conductor fitted in the track section and having crossing points and the transmission signal with a Receiving unit of the rail vehicle is received and is monitored for locating the rail vehicle for phase jumps that occur when crossing the crossing points of the line conductor.
- a method for transmitting a transmission signal to a rail vehicle located on a track section of a track for location and information transmission in which the transmitter signal is fed with a transmitter into a line conductor fitted in the track section and having crossing points and the transmission signal with a Receiving unit of the rail vehicle is received and is monitored for locating the rail vehicle for phase jumps that occur when crossing the crossing points of the line conductor.
- the occupancy of the track section is determined by the rail vehicle and that the transmitter is controlled in such a way that, after the occupancy has been determined, an unmodulated transmission signal for location and after expiry after a predetermined period of time, emits a modulated transmission signal for transmitting information, the predetermined period of time being dimensioned such that it is sufficiently long for locating on the rail vehicle side.
- the method according to the invention can be carried out particularly cost-effectively and thus advantageously if a track circuit or a rail contact is used to determine the occupancy.
- the figure shows an arrangement for transmitting a transmission signal S from a control center 3 to a rail vehicle 12 located on a track section 6 of a track 9 assigned to the control center 3 for location and information transmission.
- the control center 3 has a transmitter 15 which transmits the transmission signal S m to the track section 6 attached, crossing line K having 18 feeds.
- a reception unit 21 is provided in or on the rail vehicle 12, which receives the transmission signal S of the transmitter 15 in the control center 3 and evaluates it for locating the rail vehicle 12 in the track section 6. Specifically, the receiving unit 21 monitors the received signal for phase jumps that occur when crossing the crossing points K of the line conductor 18 by comparing the received transmission signal in phase with a comparison signal formed in the receiving unit 21 from the received signal.
- the receiving unit 21 in the rail vehicle 12 can be designed in the manner described in detail in the aforementioned German patent application DE 196 27 343 AI, in particular FIG. 2 with the associated description of the figures.
- An occupancy sensor 33 is attached to an entry point 30 of the track section 6, which detects the entry of the rail vehicle 12 into the track section 6 and transmits an occupancy signal B indicating the occupancy of the track section to the control center 3.
- the occupancy sensor 33 is connected to a switching device 36 in the control center 3, which in turn is connected to the transmitter 15 in the control center 3.
- the switchover device 36 controls the transmitter 15 in the control center 3 via corresponding control signals ST in such a way that the transmitter 15 feeds an unmodulated transmission signal S into the line conductor 18 of the track section 6 after receiving the occupancy signal B.
- the switching device 36 also contains a delay element, not shown, which, after a predetermined period of time, which follows the reception of the occupancy signal B from the occupancy sensor 33, transmits the transmitter 15 to a modulated transmission mode by means of a corresponding control by means of the control signal ST and thus switches to a delivery of a modulated transmission signal S.
- the occupancy sensor 33 can be a rail contact or a track circuit with which the vehicle can be driven on Track section 6 is determined by the rail vehicle 12.
- the switching device 36 with its delay element can be formed, for example, by a suitably programmed computer which is connected to the transmitter 15 and controls it.
- the locating of the rail vehicle and the transmission of information are carried out as follows:
- the transmitter 15 is switched by means of the switching device 36 the control center 3 switched to an unmodulated transmission mode.
- the unmodulated transmission signal S is received by the receiving unit 21 of the rail vehicle 12.
- a comparison signal is generated from the received signal, which is synchronized in phase with the received signal. If the received signal then falls below a lower threshold value in terms of amplitude and then again an upper threshold value, it is assumed in the receiving unit 21 that the received signal has passed through a zero crossing, which would be due to the passage of an intersection K of the line conductor 18.
- the comparison signal is compared with the received signal in order to ensure that a crossing point has actually been passed and to achieve a precise location of the rail vehicle 12 ; if it is determined that the expected phase jump of 180 ° has occurred, a crossing point signal indicating the passage of a crossing point K of the line conductor 18 is generated in the receiving unit 21 in the rail vehicle 12, which signal is used in the rail vehicle 12 for the rail location.
- the switchover device 36 is switched from unmodulated transmission mode to modulated transmission mode, such as how the distance between the intersection points of line conductor 18 with one another or the average entry speed of rail vehicle 12 into track section 6 is to be specified. Information transmission between the control center 3 and the rail vehicle 12 is then possible with the modulated transmission mode.
- the arrangement shown in the figure can be used particularly advantageously, for example, in the station area, namely when the occupancy sensor 33 with its entry point 30 is located in front of the station area, viewed in the direction of travel, so that the entry of the rail vehicle 12 into the station area is determined at an early stage .
- the transmitter 15 of the control center 3 is switched to unmodulated transmission mode in order to achieve high-precision locating of the rail vehicle 12 in the track section 6.
- the system then switches to modulated transmission mode, which then enables information to be transmitted between the control center 3 and the rail vehicle 12.
