Description

[0001] Uncoupling system, automatic train coupling and rail vehicle with an automatic train coupling with such an uncoupling system and method for uncoupling an automatic coupling mechanically coupled to a counter-train coupling

[0002] The present invention relates generally to track-guided vehicles and, in particular, to rail vehicles. More specifically, the invention relates to a decoupling system for an automatic train coupling for a rail vehicle and a train coupling with such a decoupling system, as well as a method for decoupling an automatic train coupling mechanically coupled to a counter train coupling.

[0003] An automatic train coupling is understood in particular to be a coupling for the mechanical connection of rail-bound vehicles, which automatically creates a mechanical connection when it meets a counterpart train coupling. Such automatic train couplings generally have a coupling head with a coupling housing and a coupling lock with a locking device. The coupling lock is designed as a rotary lock with a coupling eye and a frog, whereby the frog can be rotated about a main axis, namely between a coupled position and an uncoupled position. The coupling eye is connected to the frog by a first end or end region so that it can be rotated about a coupling eye axis and has a second free end or a second free end region. The frog has a mouth for receiving a corresponding second end or end region.a corresponding second end portion of a coupling eye of a counter-coupling coupling head. The uncoupled position is also generally referred to as the ready-to-couple position, since in this position the train couplers of the two car bodies can be moved toward each other and then coupled.

[0004] Uncoupling, i.e. breaking the mechanical connection between two coupled train couplings by moving the coupling lock of at least one of the train couplings from a coupled to an uncoupled position, depends on the area of ​​application of such train couplings. For example, train couplings for coupling two rail vehicles in a rail vehicle formation for passenger transport are equipped with an automatically operated uncoupling device, usually a hydraulic uncoupling device, which is controlled in response to an actuation request to move the coupling lock from a coupled to an uncoupled position. Such rail vehicle formations with a traction vehicle are relatively static in terms of their structure and are only rarely uncoupled, i.e. separated. The separation of two rail vehicles in such a formation takes place centrally by actuating an activation device on the traction vehicle.This eliminates any chance of incorrect operation.

[0005] The situation is different with such train couplings on freight wagons. These are equipped with a mechanical uncoupling device, which, in the form of rods or cables, transmits an actuating force exerted manually by the operator to the coupling lock and moves the coupling lock from the coupled to the uncoupled position. These also lack the electrical connection between the coupled wagons, which would enable automatic central control.

[0006] The first versions of an automated uncoupling device currently being tested in freight trains are characterized by an electromechanical or electrohydraulic drive, which is arranged on the train coupling or integrated into the train coupling and can be operatively connected to the coupling lock. For this purpose, a control device is assigned to the uncoupling devices, to which an actuation request in the form of an uncoupling signal is fed and which controls the electromechanical or electrohydraulic uncoupling device, in particular the actuator, accordingly. The uncoupling signal present as an actuation request can be specified, for example, via a device arranged on the car body, in particular in the form of a push-button switch. In order to be able to be actuated both when the train is stationary and at low travel speeds, this is mounted on the outside of the car body and is thus easily accessible from the outside.This requires a large, easy-to-use push button (even with gloves in winter), but also a secure design that prevents unauthorized activation. Mechanical protection via a key box would significantly limit ease of use and make it almost impossible to operate, especially while driving slowly.

[0007] The invention is therefore based on the object of designing a decoupling system for an automatic train coupling, an automatic train coupling and a rail vehicle with an automatic train coupling and such a decoupling system in such a way that, on the one hand, simple operation and accessibility of the activation device for specifying the actuation request for moving the coupling lock from a coupled to an uncoupled position is provided, but at the same time incorrect actuations, which would result in an undesired separation of a rail vehicle combination, are avoided.

[0008] The inventive solution is characterized by the features of claims 1, 10, 11, and 13. Advantageous embodiments are described in the subclaims.

[0009] A decoupling system for an automatic train coupling, in particular of a track-bound vehicle, in particular a rail vehicle in the form of a freight wagon, comprising a decoupling device with an actuator operatively connectable to a coupling lock of the train coupling for moving the coupling lock from a coupled to the uncoupled position; an activation device for specifying an actuation request for the decoupling device for moving the coupling lock from a coupled to the uncoupled position;a control device assigned to the train coupling for controlling the uncoupling device with an interface for at least indirect coupling to the activation device, characterized in that the control device comprises a second interface for coupling to a verification device for specifying verification information for the actuation request and the control device is designed and configured to evaluate the verification information specified via the second interface and, if an evaluation result verifying the actuation request is present, to control the uncoupling device in accordance with the actuation request specified by the activation device.;

[0010] A train coupling is understood to be a coupling for mechanically connecting two adjacent units, especially rail vehicles such as wagons. The connection serves to transmit both tractive and impact forces.

[0011] "Uncoupling" involves moving or moving the coupling lock of a train coupling from a position in the "coupled" operating state to a position in the "uncoupled" operating state, in which the connection with a counter-train coupling is released.

[0012] “Verification” in the sense of the invention is understood in particular to mean the confirmation or correctness of information.

[0013] The term "facility" is not to be understood purely in terms of equipment. It specifically describes the functional interaction of components. These can, for example, be decentralized facilities with spatially separated components or virtual facilities.

[0014] The term "interface" describes in particular the physical and virtual connection options assigned to the control device for communication and exchange of information internally within the control device as well as with external devices.

[0015] The solution according to the invention offers the advantage that the activation device can remain freely and easily accessible from the outside on the respective rail vehicle, in particular on at least one of the rail vehicles to be separated from one another, and does not have to be protected by separate, complex structural protective measures, whereby incorrect operation is reliably avoided due to the required verification.

[0016] The interfaces and thus also the couplings between the control device and the activation device for specifying an actuation request and / or the control device and the verification device for specifying verification information can, according to a first embodiment, be designed as a wireless connection, in particular a radio connection such as Bluetooth or WLAN. According to a second embodiment, these can be designed as a wired connection. The first embodiment offers the advantage that it is easy to manufacture regardless of structural conditions and, in particular, offers a multitude of options for selecting the type and design of the verification device, which can be easily implemented, particularly regardless of location. The second embodiment, in contrast, is relatively immune to interference.

[0017] In order to exchange information with each other and with the control device, the activation device and / or the verification device, as well as the control device, each have transmitting and / or receiving means for unidirectional or, preferably, bidirectional information exchange. The transmitting and / or receiving means are selected according to the selected information transmission method and the type and structure of the respective devices.

[0018] There are a number of options regarding the specific design of the activation device and / or the verification device.

[0019] In an advantageous embodiment, the activation device comprises a manually operable presetting device for specifying the actuation request. "Manual" means manually operated or triggered by an operator, particularly a shunter when used for freight wagons. The presetting device can be configured as a device selected from the following: a) a stationary presetting device that can be arranged in or on the rail-bound vehicle carrying the train coupling, in particular a lever, switch, button, touchscreen, or display; b) a mobile presetting device, in particular a remote control; mobile phone;

[0020] Smartphone, laptop; computer

[0021] The particularly preferred variant a) offers the advantage that the activation device is located directly on the vehicle in close proximity to the train coupling, allowing the operator to initiate the desired uncoupling process directly on site. In a particularly advantageous embodiment, the presetting device is located on the wagon, i.e., a track-bound vehicle without its own drive.

[0022] Analogously, the verification device in a first embodiment is also designed as a manually operable specification device for specifying the verification information, which can be designed in particular as a device selected from the following devices: a) a stationary specification device that can be arranged in or on the track-bound vehicle carrying the train coupling, in particular a lever, switch, button, touchscreen, display b) a mobile specification device, in particular a remote control; mobile phone; smartphone, laptop; computer

[0023] The required manual specification by an operator, preferably the same operator who triggered the actuation request on the activation device, represents an active specification of verification information, regardless of whether this occurs on a stationary or mobile device, and offers the advantage that, due to the required double actuation, incorrect actuations can be consciously perceived by the operator and thus excluded.

[0024] If, according to a), the specification is made on a specification device that can be arranged stationary in or on the rail-bound vehicle carrying the train coupling, it is conceivable in one variant to use the same specification device to specify the actuation request and the verification information. Since the specifications are made purely manually, they are made with a time offset. Although the specifications are then generally characterized by the same signal structure, the verification information can be reliably recognized based on the pattern of actuation and / or the time offset. The control device is designed and configured to recognize the verification information from the pattern of actuation of the specification device. A pattern can be regarded, for example, as an actuation of the specification device for different lengths of time for the two different pieces of information.If the same specification device is used to specify the actuation request and the verification information, the overall effort for the decoupling system can be kept very low due to the concentration of functions.

[0025] In an advantageous alternative second embodiment of the verification device, it comprises a verification information carrier device for storing static verification information or verification information that can be dynamically assigned to it, and transmitting and / or receiving means for unidirectional or bidirectional information exchange with the control device and / or an assignment device for transmitting the verification information to the verification carrier device. In this case, the operator does not necessarily have to actively participate; the information can be transmitted passively without their intervention. The only requirement is that the operator must be located with the verification device in the near field of the train coupling. In this embodiment, the verification device comprises, in particular, at least transmitting means for transmitting the verification information to the control device and at least one of the following receiving means:

[0026] - receiving means for receiving verification information transmitted by an allocation device;

[0027] - Receiving means for receiving a verification information request from the control device.

[0028] The provision of receiving means for receiving verification information transmitted by an allocation device offers the advantage of being able to continually adapt this information to increase security. The adaptation can take place at predefined intervals or upon request. The provision of receiving means for receiving a verification information request from the control device offers the advantage that communication between the verification device and the control device can take place independently by sending a request signal from the control device and sending a response signal from the verification device. In the simplest case, the operator wears an authorization system ora key with them, which for example contains a code, if the operator is in a predefined spatial area in the vicinity, for example in a radius of less than 3m to the train coupling, in particular the control device assigned to it, the key sends the information to the control device.

[0029] Single- or multi-stage verification procedures are conceivable. The latter offers the advantage of increased operational security.

[0030] The verification information can be evaluated in different ways in the control device and, if the evaluation result verifies the actuation request, the actuation request can be released to control the decoupling device. The evaluation can comprise a simple comparison or a complex algorithm. In the simplest case, the evaluation consists of a simple comparison of the verification information supplied to the control device via the verification device and a second piece of verification information stored in the control device. For this purpose, in an advantageous embodiment, the control device has a memory unit for storing a static piece of verification information or a further second piece of verification information that can be assigned to it dynamically via a third interface for coupling to an assignment device and for evaluating the verification information predeterminable by the verification device.The control device is designed and configured to evaluate the actuation request, verification information, and second verification information. In a particularly advantageous embodiment, the verification information is assigned to the verification device and to the control device via the same assignment device. An automatic train coupling for mechanically coupling with a counter-train coupling of a track-bound vehicle, in particular a rail vehicle, comprises a coupling head having a coupling head housing and a coupling lock. The coupling lock is designed in particular as a rotary lock with a coupling eye and a frog rotatable about a main axis between a coupled position and an uncoupled position. An uncoupling system according to one of claims 1 to 9 is also disclosed.

[0031] Such a train coupling is arranged on a rail-bound vehicle and serves to connect it to a counter-train coupling of an adjacent rail-bound vehicle. The activation device preferably comprises a manually operable operating device, in particular a push-button switch, which is stationary on the vehicle and coupled to the control device assigned to the train coupling. The verification device is designed as a portable mobile device. This can be, for example, a key card with storable verification information and transmitting and receiving means, or a smartphone, laptop, or remote control with an input device for the verification information by an operator. Depending on the design of the mobile device and the communication with the control device, the operator is actively required to enter the verification information themselves, or it is passively requested.

[0032] The method according to the invention for uncoupling a train coupling coupled to a counter train coupling, comprising a decoupling system assigned to the latter with a decoupling device that can be operatively connected to the coupling lock of the train coupling by moving a coupling lock of the rail vehicle coupling from a coupled to an uncoupled position, is characterized in that an actuation request for moving the coupling lock from a coupled to an uncoupled position is specified, the control device controls the uncoupling device for moving the coupling lock from a coupled to an uncoupled position, wherein control only takes place upon or after the presence of information confirming verification of the actuation request.In detail, a) an actuation request for controlling the uncoupling device to move the coupling lock from a coupled position to an uncoupled position is specified via an interface of a control device of the uncoupling device; b) verification information for confirming the actuation request is specified via a further second interface of the control device; c) the actuation request and the verification information are evaluated in the control device and, if an evaluation result confirming the verification of the actuation request is available, the control device controls an actuator of the uncoupling device in such a way that a coupling lock of the train coupling operatively connected thereto is transferred from its coupled position to its uncoupled position by means of the actuator.

[0033] In an advantageous development of the method, the control device checks, upon or after receipt of the actuation request, for the presence of verification information specified by the verification device within a predefined time period. If this information is not present, it suspends the actuation request. By ensuring that two pieces of information must always be present within a predefined, limited time period for actuation, incorrect actuations can be avoided.

[0034] The actuation request is preferably specified by an operator actively actuating a presetting device, in particular by actively actuating a control element arranged stationary on the vehicle carrying the towing coupling in the form of a lever or switch, in particular a push-button switch, which is at least indirectly coupled to the first interface of the control device. This ensures the direct reference of the actuation request to the corresponding towing coupling, since the operator must then be located directly on the vehicle.

[0035] As already explained in the explanations of the decoupling system, verification can be carried out in different ways:

[0036] Thus, in a first embodiment of the method, after specifying the activation request, the operator can enter or specify the verification information on an input device of the verification device, in particular an external mobile device, with the verification device sending this verification information to the control device. Here, too, the operator is actively required and should therefore very quickly detect accidental misoperations of the activation device.

[0037] In a second embodiment, in which the control device sends a request to the verification device to transmit the verification information to the control device, the operator can also be actively involved by prompting the operator to actively enter or specify verification information on or in the verification device. The verification device then sends the verification information to the control device as a request response.

[0038] In a third embodiment, the control device sends a request to the verification device to transmit the verification information to the control device. This verification device then sends the verification information stored or entered in the control device as a request response to the control device. This can be done, for example, via key or memory cards carrying corresponding information or codes. The operator only needs to be within the near field of the train coupling.

[0039] According to a particularly advantageous development, to increase security, verification is performed not only in a single step but in multiple steps through the repeated exchange of verification information between the control device and the verification device. To prevent unwanted access to verification information and to make external attacks more difficult, verification information is dynamically assigned to the verification device and / or the control device by an allocation device and stored therein or generated using appropriate algorithms.

[0040] The evaluation carried out in the control device can be carried out in different ways. It is conceivable to form an evaluation result from

[0041] - the direct comparison of the verification information stored in the control device or assigned to it via the allocation device and the verification information transmitted via the verification device or

[0042] - a function from the verification information stored in the control device or assigned to it via the allocation device and the verification information transmitted via the verification device, whereby if an evaluation result confirming the actuation request is available, the decoupling device is controlled in accordance with the actuation request.

[0043] The verification information provided via the verification device is particularly advantageously general information that serves as verification information for the operation of all couplings in a predefined spatial area, for example, a marshalling yard. All couplings within this spatial area are then assigned the same verification information. The operator can then be easily equipped with a verification device that does not require active operation, which contains the general information and can be easily read from it.

[0044] In the case of verification by not actively performing an action by the operator, but by automatically reading the verification information from a verification device, for example a key card containing the verification information, the authorized operator only needs to be in the near field range of the respective coupling after specifying the actuation request, for example by pressing a push button switch on a wagon.

[0045] The inventive solution is explained below with reference to figures. They show the following in detail:

[0046] Figure 1 shows a section of a rail vehicle convoy;

[0047] Figure 2 shows a simplified schematic representation of the basic structure of a decoupling system;

[0048] Figure 3 illustrates your decoupling procedure using a flow chart;

[0049] Figure 4 shows an advantageous embodiment of a decoupling system.

[0050] Figure 1 shows, based on a section of a rail vehicle assembly 1, two rail vehicles 2, 3, particularly in the form of wagons for transporting goods, arranged one behind the other and at least mechanically coupled to one another. Each of the rail vehicles 2, 3 has a train coupling 4 at the end regions facing away from one another for coupling to a compatible counter-train coupling 5 of the adjacent rail vehicle. In the case shown, the rail vehicle 2 is coupled to the counter-train coupling 5 arranged on the rail vehicle 3 via the train coupling 4 arranged thereon. The train couplings 4, 5 are designed and equipped to enable at least one mechanical connection between the rail vehicles 2, 3 for transmitting tensile and compressive forces.In addition, electrical connections, data connections, and / or fluid connections between the rail vehicles 2, 3 can also be realized via corresponding additional devices provided on or associated with the train coupling. These additional devices are assigned to the individual rail vehicle coupling 4, 5, preferably at least indirectly mounted on it.

[0051] The mechanical connection between two adjacent rail vehicles 2, 3 is achieved by bringing the coupling locks of both train couplings 4, 5 into operative connection with one another. For this purpose, each individual train coupling 4, 5 has a coupling head 6 which has a coupling head housing 7 and a coupling lock 8 with a locking device. In an advantageous embodiment shown in Figure 2, the coupling lock 8 is designed as a rotary lock with a coupling eye and a frog, wherein the frog is rotatable about a main axis of rotation between a coupled position and an uncoupled position. The coupling eye is connected to the frog at a first end so that it can be rotated about a coupling eye axis and has a second free end. For uncoupling, each individual train coupling 4 or 5 is assigned a uncoupling system 10 comprising an uncoupling device 9.

[0052] The basic structure of a decoupling system 10 is shown in a simplified schematic representation in Figure 2. This comprises a decoupling device 9 for moving the coupling lock 8 from a coupled to the uncoupled position, an electronic control device 11 for controlling the decoupling device 9, and a first activation device 12 for specifying an actuation request for the decoupling device 9. There are a number of options for specifying the actuation request. This can be done, for example, manually by actuating a switch, selecting a button, operating a lever, or inputting it via a communication medium, such as a cell phone or panel. The control device 11 comprises at least one interface device 13 for communication internally or with external devices, in particular for coupling with the first activation device 12 and the decoupling device 9.According to the invention, however, the actuation request is not immediately converted into a manipulated variable for the uncoupling device 9 in the control device 11, but only after this actuation request has been verified. For this purpose, a verification device 14 is provided for specifying verification information for the actuation request, which can be coupled to the control device 11 via an interface of the interface device 13. The control device 11 is designed and configured to evaluate the information transmitted by the verification device 14 and, upon detection of information confirming the actuation request, to implement the actuation request specified via the activation device 12 to actuate the uncoupling device 9, in particular to output the required manipulated variable or the control variable for the actuating device 16 of the uncoupling device 9 in order to actuate it.

[0053] In the simplest case, the control device 11 comprises an evaluation device 15, in which the verification information for the actuation request is evaluated. The result is output to the decoupling device 9 via the interface device 13.

[0054] The interface device 13 comprises transmitting and receiving means for information, in particular the signals representing the information for communicating with the activation device 12, the verification device 13 and the uncoupling device 9 or the actuating device 16 associated therewith.

[0055] Depending on the design of the individual devices 12 and 14, the interface device 13 comprises corresponding interfaces, in particular in the form of data interfaces, machine interfaces, network interfaces, user interfaces, etc.

[0056] The basic procedure for uncoupling is shown in Figure 3. For the desired uncoupling, for example in a marshalling yard, in the first method step an actuation request X-EK for the uncoupling device 9 for uncoupling is specified for at least one of the coupled train couplers 4, 5 via the first activation device 12. This information is fed to the control device 11. The control device 11 is designed and configured not to immediately convert the actuation request X-EK into the required actuating signal, in particular the required actuating variable Y-EK for actuating the actuating device of the uncoupling device 9, but rather to first put it "on hold", so to speak. Only when information confirming the actuation request X-EK is available as the evaluation result T is the actuating variable Y-EK output and the uncoupling device 9 actuated.There are a multitude of possibilities regarding the possibilities for verifying the actuation request X-EK and consequently also the design of the verification device 14.

[0057] A particularly advantageous embodiment of the entire uncoupling system 10 is shown in Figure 4. This shows a simplified schematic view of a section of the end region of a rail vehicle 3 with the train coupling 4 arranged thereon for interaction with a counter train coupling 5. The rail vehicle is, for example, a freight wagon, i.e. a vehicle without its own drive and without a driver's cab. The individual train coupling 4, 5 each comprises an uncoupling device 9 for actuating the coupling lock 8 from a "coupled" position to an "uncoupled" position. Each train coupling 4, 5 can be assigned such an uncoupling system 10. The structure is explained here only for the uncoupling system 10 assigned to the train coupling 4.For this purpose, the uncoupling system 10 comprises an activation device 12 which, in the case shown, is designed as a stationary and manually actuated actuating element in the form of a push-button switch. The activation device 12 preferably comprises two such actuating elements 17.1, 17.2 which are arranged in the rear end region of a rail vehicle 2 on both sides of the car body of the rail vehicle 2. The arrangement is preferably mirror-symmetrical with respect to a longitudinal axis of the rail vehicle 2. The bilateral arrangement allows an actuation request X-EK to be specified from the same side, regardless of the orientation of the rail vehicle 2. This means that at least one actuation request X-EK can always be specified via one of the actuation elements 17.1, 17.2 of the first activation device 12. Simultaneous or temporally offset specification on both actuation elements 17.1, 17.2 is also conceivable.The actuation requests - for example X-EK17.1 and / or X-EK17.2 - are fed to the control device 11 via the interface device 13 and are not implemented there until information verifying this actuation request X-EK is available, i.e. they are put on hold, so to speak, and preferably deleted completely after a predefined period of time has elapsed. The actuation request X-EK17.1 or X-EK17.2 is verified via a verification device 14. In the case shown, this is done via an external device, which is in the form of a mobile device 18, for example. The mobile device 18 is designed and configured to communicate or be able to communicate with the control device 11. Depending on the design, the operator must actively provide or withhold the verification information.or this is automatically transmitted to the control device 11 as a response to the mobile device 18 upon request from the latter. In particular, when the mobile external device 18 is designed as a verification information carrier device in the form of a key card with the option of storing the verification information and with transmitting and receiving means for communicating with the control device 11, the latter can request a code stored in the key card as verification information from the control device 11 as a verification information request and transmit it to the control device 11 as a request response without any action on the part of the operator carrying the key, provided the operator is in the near field range of the control device 11. Communication between the verification device and the control device takes place via near field communication.

[0058] Preferably, the code of the key and thus the verification information of the verification device is not static but is reassigned to the key at predefined intervals or as required via an assignment device which takes the form of an external control device, for example a control unit of a marshalling yard or another higher-level central control device of the verification device. The assignment can be made, for example, in such a way that the respective verification information applies to all vehicles in a marshalling yard. For this purpose, the same code is preferably stored or stored in the control devices 11 for the individual couplings of the vehicles located in the marshalling yard for comparison purposes.assigned to the control device 11, so that the presence of a verification in the control device 11 can be determined by simply comparing the code transmitted by the verification device 14 with the code stored in the control device 11. The operator only needs to be in the near field of the respective coupling to which he or she has actively assigned an actuation request. This simplifies the maneuvering process while simultaneously fulfilling increased safety requirements against incorrect or unauthorized actuation or specification of the actuation request.

[0059] The predefined spatial area in which such a verification device is effective preferably extends beyond the marshalling yard. A further expansion is also conceivable, for example, to include the marshalling yards of a company.
