Description
Technical Field
The invention relates to a method for determining the direction of travel of a vehicle, in particular a rail vehicle, traveling on a travel route, wherein at least one information signal is transmitted by a route-side device, in particular a transponder, in the form of electromagnetic waves and is received by a vehicle-side device.
Background
Methods of the type described above are used to determine the direction of travel of, for example, rail vehicles equipped with Automatic Train controllers (ATC-Automatic Train Control) or European Train Control systems (ETCS-European Train Control System). Such modern train control systems are used for greater automation and thus greater passenger capacity and line efficiency. In order to ensure the reliability of the train system despite the increased capacity, subsystems such as Automatic Train Protection (ATP) and Automatic Train Operation (ATO) are used. For example, the ATP system calculates a minimum interval between consecutive trains to ensure safe operation. Of course, the calculation of a safe separation between two trains is only guaranteed if the position of each individual train is known. In europe, for example, the european transponder Transmission System (Eurobalisen Transmission System) is used, among other systems, with which a train can calculate its current position. The european transponder transmission system complies with the ETCS standard and is essentially composed of a line-side device, a so-called transponder, in particular a european transponder, which is arranged along the driving route.
On the train side, there is a corresponding vehicle-side device, which first of all emits a continuously energized magnetic Field, usually 27MHz, the so-called remote Field (telepower Field). When a train passes by or approaches the transponder, the emitted magnetic field induces a voltage in the transponder, by which the transponder is activated. As a result of the activation, the transponder starts to emit an information signal in the form of an electromagnetic wave, which information signal is typically transmitted at a carrier frequency of 4 MHz. The information signal is received by the device on the vehicle side while passing the transponder. The information signal is used to transmit a data message which contains, for example, the identification code of the transponder. The device on the vehicle side can determine the transponder position from the database on the basis of the identification code of the transponder. Furthermore, a point in time at which the information signal is received from the transponder is determined. Thus, the device on the vehicle side can determine the exact position of the train when it passes the transponder. Alternatively, the data message may also directly contain the location of the transponder, so that no check in the database is required.
In addition to the position of the vehicle, the train controller also requires the direction of travel of the train as it travels over the transponder. The travel direction may be, for example, west or east along a predefined travel route. A train with an automatic train control system (ATC) can only enter into automatic operation if the position and the direction of travel are determined. If one of these pieces of information is missing, the train must be controlled manually, i.e. by the train driver, and subjected to certain requirements, such as a lower maximum speed, for example. This results in an undesirable delay.
The direction of travel is usually determined by driving over the second transponder and evaluating its information signal. The driving direction can be uniquely determined from the two transponder positions and the points in time at which they are read out. However, the transponders are usually arranged at a certain distance from one another, so that the train must first run in manual mode during this time. This is especially problematic if the train loses its position for any reason and has to be reffered.
An alternative system is described, for example, in EP 0667275 a1, which determines the direction of travel without the aid of transponders. The described method uses a navigation system, such as a GPS or compass, to determine the direction of travel. However, this method cannot be used in tunnels, for example. Another method for determining the direction of travel is described, for example, in EP 298699 a1, in which an RFID transmitter is used. However, this method is very complicated to implement.
Disclosure of Invention
The object of the present invention is therefore to provide a method of the type mentioned at the outset, with which the direction of travel and the position of the vehicle can be determined as quickly and in a simple manner as possible.
According to the invention, this object is achieved by the initially mentioned method in that electromagnetic waves are transmitted in a first transmission direction with a first characteristic and in a second transmission direction with a second characteristic that can be distinguished from the first characteristic, the electromagnetic waves with the first characteristic and the electromagnetic waves with the second characteristic are received, and a travel direction and/or a position are determined therefrom, wherein the first transmission direction extends at least partially in the first travel direction and the second transmission direction extends at least partially in the second travel direction.
The advantage of the solution according to the invention is that the vehicle-side device can determine the direction of travel immediately when passing a single line-side device, for example a transponder, or already before this.
For a vehicle traveling on a travel route, the vehicle travels either in a first direction of travel or in a second direction of travel, the second direction of travel being substantially opposite the first direction of travel. In the solution according to the invention, the electromagnetic waves of the information signal are transmitted in a first transmission direction with a different characteristic than in a second transmission direction. The first transmission direction extends at least partially in a first direction of travel, and the second transmission direction extends at least partially in a second direction of travel. Thus, there is a recognizable difference for the vehicle-side device between the device passing or approaching the line side in the first direction of travel and the device passing or approaching the line side in the second direction of travel, there is a code. Since the vehicle-side device receives the electromagnetic wave having the first characteristic and the electromagnetic wave having the second characteristic when passing by or approaching the line-side device, the difference can be determined and the traveling direction can be determined therefrom.
The distinguishable characteristic of the electromagnetic wave of the information signal may be, for example, the carrier frequency, modulation (e.g., CDMA modulation), or polarization. In any case, it is thereby distinguished that the electromagnetic waves emitted in the first transmission direction and the electromagnetic waves emitted in the second transmission direction are different. On the vehicle-side device, it is known, for example, from a database or a layout diagram, in which transmission direction the electromagnetic wave is transmitted with which characteristic. The travel direction can thus be determined from the evaluation of the received electromagnetic waves when passing through the device on the route side.
Since the position of the antenna relative to the vehicle-side device can also be derived from the received waves, the position of the vehicle can also be determined by means of the invention.
The solution according to the invention can be further extended by the advantageous embodiments described below.
Thereby, it is possible to use different polarizations as the first and second characteristics of the electromagnetic wave, so that the electromagnetic wave is transmitted in a first transmission direction with a first polarization and in a second transmission direction with a second polarization that can be distinguished from the first polarization. This has the following advantages: it is technically possible to produce different polarizations in different transmission directions in a very simple manner, and this design can therefore be implemented very simply and at low cost. In the ideal case, the polarizations are oriented orthogonally to each other, for example horizontal and vertical or RHCP (right-hand circular polarization) and LHCP (left-hand circular polarization).
In order to be able to determine the direction of travel and/or the position with greater reliability, the course, in particular the amplitude course, of the received electromagnetic waves having the first property and the course, in particular the amplitude course, of the received electromagnetic waves having the second property can be determined, and the direction of travel or the position can be determined therefrom. The maximum value of the received electromagnetic waves having the first or second characteristic can be determined from the course with respect to time or with respect to the route of travel, so that the travel direction can also be read out uniquely. Furthermore, the relative position can be determined more accurately and reliably depending on the course of the route when passing through the installation on the route side.
In a further advantageous embodiment, the electromagnetic waves having the first characteristic can be optimally received at least temporarily, and the electromagnetic waves having the second characteristic can be partially filtered out. In this way, a very different maximum value is generated in the course of the electromagnetic wave having the first property than in the course of the electromagnetic wave having the second property. Thereby, the difference between passing or approaching in the first direction of travel and passing or approaching in the second direction of travel becomes clearer. Of course, the first and second characteristics are interchangeable with respect to the optimized reception and filtered correlations.
The invention further relates to a line-side device, in particular a transponder, for transmitting at least one information signal in the form of an electromagnetic wave to a vehicle, in particular a rail vehicle, passing the device, wherein the device has at least one antenna which is designed for transmitting the information signal in the form of an electromagnetic wave. In order to solve the above-mentioned technical problem, it is provided according to the invention that the antenna is designed to transmit electromagnetic waves with a first characteristic in a first transmission direction and to transmit electromagnetic waves with a second characteristic, which is distinguishable from the first characteristic, in a second transmission direction.
The line-side device can advantageously be further expanded by: the antenna is designed for transmitting electromagnetic waves with at least two different polarizations as first and second characteristics, so that the electromagnetic waves are transmitted with a first polarization in a first transmission direction and with a second polarization, distinguishable from the first polarization, in a second transmission direction. As already mentioned above, polarization is a property that can be easily changed and is therefore simple and low cost.
In order to provide these different polarizations of the electromagnetic wave in a simple manner, the device may have at least one dual polarized antenna or two single polarized antennas. Dual polarized antennas and single polarized antennas are generally known and can therefore be obtained at low cost. A dual-polarized antenna can, for example, produce two different polarizations via two outputs.
The invention further relates to a device for a vehicle for determining a direction of travel and/or a position, wherein the device has at least one antenna which is designed to receive at least one information signal in the form of electromagnetic waves from a line-side device, in particular a line-side device according to one of the aforementioned embodiments. In order to solve the above-mentioned object, the invention provides that the antenna is designed for receiving electromagnetic waves, wherein the electromagnetic waves have a first characteristic in a first transmission direction and a second characteristic that can be distinguished from the first characteristic in a second transmission direction, and the device has at least one evaluation device that determines a direction of travel and/or a position from the received electromagnetic waves, wherein the first transmission direction extends at least partially in the first direction of travel and the second transmission direction extends at least partially in the second direction of travel.
In an advantageous embodiment of the device for a vehicle, the device can be designed for receiving electromagnetic waves having different polarizations as the first and second characteristics, such that the electromagnetic waves have a first polarization in a first transmission direction and a second polarization in a second transmission direction, which is distinguishable from the first polarization. This has the advantage, already described above in the method according to the invention, that different polarizations of the electromagnetic wave can be generated in a simple manner.
In a further advantageous embodiment, the device can have at least one dual-polarized antenna or two single-polarized antennas. As already mentioned above, this is advantageous because both dual-polarized and single-polarized antennas can be obtained at low cost. A single dual-polarized antenna can produce two different polarizations via two outputs, which are emitted in two directions, respectively.
The invention further relates to a vehicle, in particular a rail vehicle, having a device for determining a direction of travel and/or a position, which device is designed according to one of the embodiments of the device for a vehicle mentioned above.
Finally, the invention relates to a device for determining the direction of travel and/or the position of a vehicle traveling on a route, in particular a rail vehicle, having at least one route-side device, in particular a transponder, which is designed to transmit at least one information signal in the form of electromagnetic waves, and having at least one vehicle-side device, which is designed to receive electromagnetic waves from the route-side device. In order to design the driving direction determination or the position determination particularly simply and reliably, it is provided according to the invention that the route-side device is designed according to one of the previously mentioned embodiments, and the vehicle-side device is likewise designed according to one of the previously mentioned embodiments.

Detailed Description
An exemplary embodiment of the device according to the invention in fig. 1 is first described.
Fig. 1 schematically shows an exemplary device 1 according to the invention, with which device 1 the driving direction F, F' of a vehicle 2 can be determined.
The device 1 has a vehicle-side device 3 and a line-side device 4, 4'. The vehicle-side device 3 is arranged in or on the vehicle 2, and the route-side devices 4, 4 'are arranged in the region of the travel route 5, in which the vehicle 2 is moved in a first travel direction F or in a second, opposite travel direction F'. In the exemplary embodiment of the figures, the vehicle 2 is designed as a rail vehicle, the track-side devices 4, 4' are designed as transponders, for example european transponders, and the vehicle-side device 3 is designed as a transponder reader. A large number of track-side devices 4, 4' are arranged in the usual manner along the travel track 5 and, as shown in fig. 2 for example, are arranged between the rails 6 of the travel track.
The vehicle-side device 3 includes an antenna 7, an analysis device 8, and a communication device 9.
The line-side device 4, 4 'can be designed as a fixed line-side device 4', for example as a fixed data transponder, or alternatively as a switchable line-side device 4, for example as a transparent data transponder. In contrast to the fixed line-side device 4', the switchable line-side device 4 has a connection to a line-side signaling device 10, by means of which signaling device 10 information can be transmitted to or from a central control station (not shown). The design of the line-side device 4, 4' as fixed or switchable is not essential to the invention.
In operation of the device 1 according to the invention, the line-side devices 4, 4' are activated by the vehicle-side device 3, as is customary in the prior art. For this reason, the antenna device 7 of the vehicle-side device 3 continuously transmits a magnetic Field 11 having a frequency of, for example, 27MHz, and this magnetic Field may also be referred to as a remote power Field (telepower Field). When the vehicle 2 passes the line-side device 4, 4 ', the device 4, 4' is supplied with power and activated by the magnetic field 11. Subsequently, the line-side device 4, 4' starts transmitting the information signal 12. The information signal 12 contains data messages, in which, as is known in the art, identification codes or position data of the line-side devices 4, 4' are contained. Using the data transmitted by the information signal 12, the vehicle-side device 3 can determine the position of the route-side device 4, 4 ', and thus also the position of the vehicle 2 at the point in time when the vehicle-side device 3 passes the route-side device 4, 4'.
The features and functions of the device 1 according to the invention described up to now correspond substantially to the prior art, as it is found, for example, in ETCS system applications.
Further features and functions according to the invention will now be described below, in particular with reference first to fig. 2 and 3.
Fig. 2 shows in a schematic way one of the line-side devices 4 after activation. The line-side device 4 transmits the information signal 12 in the form of electromagnetic waves 13, 13'. The electromagnetic waves 13, 13' constitute an electromagnetic field which in fig. 2 and 3 essentially assumes a conical shape.
For transmitting the electromagnetic waves 13, the line-side devices 4, 4' have an antenna 14. In the exemplary embodiment of fig. 2 and 3, the antenna 14 is a dual polarized antenna. Alternatively, two single polarized antennas may be used. As shown in fig. 2, the antenna 14 transmits the electromagnetic wave 13 in a first transmission direction + Y. Likewise, the antenna 14 transmits electromagnetic waves 13' in a second transmission direction-Y. The electromagnetic wave 13 in the first transmission direction + Y differs from the electromagnetic wave 13' in the second transmission direction-Y by at least one characteristic. In the exemplary embodiment in the figures, the characteristic is polarization. That is, the electromagnetic wave 13 has a first polarization, and the electromagnetic wave 13' has a second polarization different from the first polarization. Thus, according to the invention, the information signal 12 is transmitted by means of electromagnetic waves 13, 13 ', which waves 13, 13' respectively carry the data required for positioning, but with different polarization directions. The first transmitting direction + Y extends substantially in the first travel direction F and the second transmitting direction-Y extends substantially in the second travel direction F'. The first transmission direction + Y extends exactly opposite to the second transmission direction-Y.
Fig. 3 shows, in a very simplified manner, a vehicle 2 having a vehicle-side device 3, which is moved on a driving route 5 in a first driving direction F and approaches a route-side device 4 and then passes the route-side device 4. In fig. 3, the line-side device 4 has been activated and, as described with reference to fig. 2, transmits the information signal 12 in the form of electromagnetic waves 13, 13'. The line side device 4 in fig. 3 is the same as in fig. 2.
In the exemplary embodiment in fig. 3, the vehicle-side device 3 has two antennas 7, 7'. Each antenna 7, 7' is designed as a dual-polarized antenna. Alternatively, two single-polarized antennas transmitting in two directions are also possible. A single dual polarized antenna may also be used. In the exemplary embodiment of fig. 3, the first antenna 7 'is designed to receive electromagnetic waves 13 having a first polarization, to be precise in the first direction of travel F and in the second direction of travel F' to receive electromagnetic waves 13 having the first polarization. Conversely, the second antenna 7 ' is designed to receive electromagnetic waves 13 ' with a second polarization, to be precise also in both directions of travel, electromagnetic waves 13 ' with a second polarization. The receiving areas of the antennas 7, 7' respectively appear conical in fig. 3. The same color indicates the same polarization compared to the line side device 4.
The diagram in fig. 4 shows the amplitude profile of the received signal of the first antenna 7' when approaching or passing the line-side device 4. Here, the right graph 15 shows the amplitude of the co-polarized electromagnetic wave 13, and the left graph 16 shows the amplitude of the cross-polarized electromagnetic wave 13'. With the same polarization, the antenna 7' is optionally designed for receiving electromagnetic waves 13 of the same polarization. The cross-polarized waves 13 'are mostly filtered out because the antenna 7' is not optimized for receiving cross-polarized waves. The polarization loss is high.
Fig. 5 shows the amplitude profile of the received signal of the second antenna 7 when approaching or passing the line-side device 4 in the direction of travel F. The left-hand diagram 17 now shows the amplitude of the co-polarized electromagnetic wave 13' and the right-hand diagram 18 shows the amplitude profile of the cross-polarized electromagnetic wave 13. This time, the antenna arrangement 7 is optimized for the same polarized wave 13'. The cross-polarized waves 13 are mostly filtered out and only produce a weaker signal.
In fig. 4 to 6, the distance in the Y direction (fig. 2) is shown on the abscissa and the amplitude calculated from the received wave is shown on the ordinate, respectively.
Fig. 6 shows the combined amplitude profile calculated as a combination of fig. 4 and 5. The right-hand graph 19 shows the amplitude profile of the electromagnetic waves received by the antenna arrangement 7', while the graph 20 shows the amplitude profile of the electromagnetic waves received by the antenna arrangement 7. The maximum value of the trend is calculated and the position a, b of the maximum value and the order in which the maximum values occur are stored. Additionally, the intersection of the graphs 19, 20 and its position C are calculated and stored.
The invention determines the direction of travel F, F' and/or the position 0 according to at least one of the profiles shown in fig. 4 to 6.
The antenna device 7' records first the low amplitude and then the high amplitude, and the antenna device 7 records first the high amplitude and then the low amplitude. It is also known that the line-side device 4 transmits electromagnetic waves 13 with a first polarity in a first transmission direction + Y and electromagnetic waves 13' with a second polarity in a second transmission direction-Y. This information may be retained in a database. Thus, the analysis device 8 can determine that the vehicle 2 is moving in the first driving direction F.
Furthermore, the relative position of the vehicle or of the vehicle-side device 3 relative to the route-side device 4, 4' is determined from the graphs 19, 20. In fig. 4 to 6, the position where Y is 0 is the exact position of the line-side device 4, 4'. This can be done, for example, depending on the position c of the intersection in fig. 6 or depending on the midpoint between positions a and b
And (4) determining. To improve accuracy, all three points may be used.
One condition for correct functioning when receiving the information signal 2 is that the antennas 7, 7', 14 of the vehicle-side or line-side device are positioned in the far field (Fernfeld). In the far field, the polarization is stable. This can be supported by using higher frequencies, as described for example in the not yet published patent application DE 102016215696. By higher frequencies, the near field region can be reduced and the far field region can be enlarged accordingly.
