Description

As part of the operation or the control of track-bound vehicles, which may be, for example, track-guided vehicles with rubber tires or magnetic levitation vehicles, different treatment by control devices may be appropriate for different types of vehicles. For example, in the case of track-bound vehicles in the form of rail vehicles on the part of an interlocking in the context of securing the travel of the respective vehicle, a danger point distance and / or a Durchrutschweg for each vehicle depending on the different braking distance of goods and local trains determined or adjusted as needed become.

Usually, the types of trains here in mixed traffic, ie, for example, in a simultaneous operation of freight and local trains, distinguished in the context of the control technology by a Zuglenkung means train and train number tracking. However, this has the disadvantage that this procedure is a non-safe method according to safety integrity level (SIL) 0 to 2. In the case of a disturbance of the train steering arises here for safety reasons, the need to determine the routes for all trains with long landslide or large danger point intervals or set. As a result, for example, for light rail trains an increase in the train following time, ie a reduction in the number of vehicles per unit time, which can travel a route result, which can cause significant disruption of the operation.

A method according to the preamble of claim 1 is known from the published European patent application EP 1 693 271 A1 known. In this case, in the case of detection of an activated in the direction of travel left state transmission device, an emergency brake signal is transmitted with respect to the relevant vehicle.

The present invention has for its object to provide a particularly reliable and at the same time relatively easy to implement method for operating a track-bound vehicle.

This object is achieved by a method for operating a track-bound vehicle, wherein the presence of the vehicle-side train-influencing device is detected by a track-side device by detecting a radiated from a vehicle-side train-influencing device of the track-bound vehicle, the detection of the trackside device the information signal indicative of the vehicle-mounted train control device is transmitted to a control device and the information signal is taken into account by the control device during the securing of the travel path of the tracked vehicle when determining a danger point distance and / or a slipping path for the tracked vehicle.

The present invention is based on the finding that a trackside, ie, for example, made with components of the outdoor installation of an electronic interlocking differentiation of different types track-bound Vehicles in operational practice brings significant benefits. According to the invention, a distinction advantageously takes place in that the track-side device detects the presence of the vehicle-side train-influencing device by detecting a signal radiated from a vehicle-side train-influencing device of the track-bound vehicle. This makes it possible to consider the presence or absence of the on-board train control device as part of the operation of the tracked vehicle as a criterion for the type of tracked vehicle. For this purpose, the information signal indicating the detection of the vehicle-side train-influencing device is transmitted to the control device by the trackside device. In this case, the control device can in particular be a central control device, for example in the form of a signal box or a control station. On the part of the control device, based on the received information signal, it is possible to distinguish different types of vehicles or trains in the form of vehicles equipped with or not equipped with a train control device. Due to the fact that on-board train-control devices are usually prescribed as a function of the permissible maximum speed of the respective vehicle, additional information can optionally be derived therefrom which can also be taken into account in the further operation of the track-bound vehicle. For example, in the field of rail transport, freight trains and long-distance trains are usually equipped with on-board train control facilities, while local trains operating at comparatively low speeds depend on the particular circumstances or even regularly is not the case.

The method according to the invention is advantageous because it enables automatic recognition of track-bound vehicles equipped with a vehicle-side train-influencing device by means of the track-side device. For this purpose, the signal emitted by the vehicle-side train-influencing device is advantageously detected, so that it is advantageously possible to dispense with additional vehicle-mounted components. Thus, in a plurality of different train control systems, in particular systems for punctiform train control, for purposes of communication with a trackside device, which may be, for example, a track resonant or a balise, a signal emitted by a vehicle-mounted device. This signal may, for example, have a predetermined frequency or also a plurality of predetermined frequencies. Regardless of the nature of the radiated signal, the vehicle-side train-influencing device is preferably already designed in accordance with the highest safety requirement level SIL 4, so that a corresponding realization of the track-side components overall highest safety requirements can be met. Moreover, in the case of a defective on-board train control device, the tracked vehicle advantageously reacts to the safe side so that it drives correspondingly slower, thereby reliably avoiding potential hazards due to the failure to recognize the presence of an on-board train control device.

According to the invention, the information signal from the control device in the context of securing the infrastructure of the track-bound Vehicle considered. This is advantageous since, in particular when securing the track of track-bound vehicles, it is expedient to distinguish those vehicles which have a vehicle-side train-influencing device and those vehicles which do not have a corresponding vehicle-side train-influencing device. For example, rail vehicles not equipped with an on-board train control device generally have a reduced maximum permissible speed, which may be, for example, 60 km / h or 100 km / h. The corresponding information can thus be considered advantageously in the context of securing the travel path of the respective vehicle.

According to the method according to the invention, the information signal is taken into account by the control device in the course of securing the travel path of the track-bound vehicle when determining a danger point distance and / or a slipping path for the track-bound vehicle. This is advantageous since the information signal enables danger point distances and / or slip distances to be determined or set as required as a function of the different braking distance length, for example of freight and local trains. As a result, it is advantageously possible to increase the train sequence independently of the functionality and the reliability of a component used for train guidance, resulting in an overall optimization of the traffic flows.

According to a particularly preferred development, the method according to the invention is embodied such that the information signal is assigned to the respective track-bound vehicle by the control device and, based thereon, by the control device such track-bound vehicles, which have a vehicle-side train control device, are distinguished from such other track-bound vehicles that have no vehicle-side train control device. In this case, the assignment of the information signal to the respective track-bound vehicle can be effected, for example, with the additional use of information about the location of the track-bound vehicle. Such information may, for example, be an allocation information indicating that a particular track-bound vehicle is occupying or driving a route section in which the track-side device is arranged. Thus, for example, a control device in the form of an interlocking or a control center usually the respective positions of the monitored or controlled track-bound vehicles known. As a result, a distinction between vehicles with and without vehicle-side train control device is thus advantageously made possible by the control device, so that even for those track-bound vehicles that have no vehicle-side train control device based on the absence of an information signal a clear statement of the kind "no on-board train control device present "is possible.

Basically, in the context of the method according to the invention, the vehicle-side train-influencing device can be a component of any train-influencing or train-securing system. In the sense of a reliable detection of the presence of the vehicle-side train-influencing device, basically only a permanent or at least substantially permanent radiation of the signal is required. Depending on the respective train control system, the respective type of implementation may be used distinguish the on-board train control device.

According to a further particularly preferred embodiment of the method according to the invention, the track-side device detects a signal emitted by at least one vehicle resonant circuit, in particular at least one Indusi vehicle resonant circuit, of the vehicle-side train influencing device. This is advantageous because known train control systems often work with on-board train control devices which emit a signal of predetermined frequency or a plurality of signals of predetermined frequencies by means of at least one vehicle resonant circuit. Corresponding train control systems can be, for example, the systems Integra-Signum, ETCS (European Train Control System) or KVB (Controle de vitesse par balises). In addition, the vehicle-side train-influencing device may advantageously be, in particular, an Indusi vehicle resonant circuit, ie a vehicle resonant circuit of the inductive train control or train influencing system Indusi. In this system, which is used for example in long-distance and freight traffic in Germany, Austria and the successor countries of Yugoslavia, the vehicle-side train control device in the form of a vehicle resonant circuit, which is also referred to as a vehicle magnet, the frequency 500 Hz, 1000 Hz and 2000 Hz permanently off. By detecting or recognizing one or more of these signals, it is thus advantageously possible to identify the vehicle-side train-influencing device in the form of the at least one vehicle resonant circuit and to differentiate it in the wake of track-bound vehicles with and without corresponding vehicle-side train-influencing device.

According to a further particularly preferred embodiment, the method according to the invention is developed in such a way that the signal emitted by the vehicle-side train-influencing device is detected by a track-side device having at least one coil. This is advantageous since corresponding track-side devices can be realized comparatively inexpensively and enable reliable detection of the signal emitted by the vehicle-side train-influencing device. In this case, the trackside device may preferably be a trackside component that is used within the scope of the respective train control system for communication with the vehicle-side train-influencing device and thus already exists anyway. Thus, the trackside device may for example have a track resonant circuit, also referred to as a track magnet, as used in the context of the train control system Indusi for transmitting information to the vehicle-side train-influencing device. Alternatively, however, it is also possible for the trackside device to be another component which is not also used in the context of the respective train control system. In this case, the coil may be formed, for example, as part of a detection device, also referred to as a switching magnet, of the trackside device.

With regard to the arrangement, the present invention has the object to provide an arrangement that supports a particularly reliable and at the same time comparatively easy to implement method for operating a track-bound vehicle.

This object is achieved by an arrangement with a control device and a trackside device with a detection device for detecting the presence of a vehicle-side train control device of a track-bound vehicle by detecting a radiated from the vehicle-side train control device signal and a transmission device for transmitting a detection of the on the vehicle-side train control device indicating information signal to the control device, wherein the control device is designed such that it takes into account the information signal in the context of securing the track of the track bound vehicle in a determination of a danger point distance and / or a slip path for the tracked vehicle.

The advantages of the arrangement according to the invention essentially correspond to those of the method according to the invention, so that in this regard reference is made to the corresponding explanations above. The same applies with regard to the preferred developments of the arrangement according to the invention mentioned below with regard to the respective corresponding preferred developments of the method according to the invention, so that reference is also made in this regard to the corresponding explanations given above.

Preferably, the arrangement according to the invention can be further developed such that the detection device is designed to detect a signal emitted by at least one vehicle resonant circuit, in particular at least one Indusi vehicle resonant circuit, the vehicle-side train influencing device.

According to a particularly preferred development of the arrangement, the detection device has at least one coil.

According to a particularly preferred development, the arrangement according to the invention is configured such that the control device is designed such that it assigns the information signal to the respective track-bound vehicle and based on such track-bound vehicles, which have a vehicle-side train control device of such other track-bound vehicles differs that have no on-board train control device.

In the following the invention will be explained in more detail with reference to an embodiment. This shows the

figure

for explaining an embodiment of the method according to the invention in a schematic sketch of an embodiment of the inventive arrangement.

The figure shows a track-bound vehicle 10 in the form of a rail vehicle. The track-bound vehicle 10 has a Vehicle-side train-influencing device 20, which in the context of the exemplary embodiment described should be a vehicle resonant circuit or a vehicle magnet of the train control system Indusi.

During its journey along the track or the route 100, the vehicle-side train-influencing device 20 radiates permanently a signal or a plurality of signals S from. As part of the train control system Indusi this is a signal with the frequencies 500 Hz, 1000 Hz and 2000 Hz.

The signal S radiated from the vehicle-side train influencing device 20 is detected by a trackside device 40 by means of a detection device 41, which may comprise, for example, at least one coil for detecting one or more of the radiated from the vehicle-side train control device 20 frequencies, and thus thus the Presence of the on-board train control device 20 detected. This means that the track-side device 40 recognizes that the track-bound vehicle 10 has a vehicle-side train-influencing device 20 on the basis of the signal S.

Upon detecting the vehicle-side train-influencing device 20, an information signal IS indicating or indicating a detection of the vehicle-side train-influencing device 20 is transmitted to a control device 60 via a communication link 50 by a transmission device 42 connected to the detection device 41 , In this case, the communication connection 50 may be both a wireless and a wired connection. To unwanted influences To avoid between different modules, the transmission of the information signal IS in the case of a wired transmission in this case, for example, by means of a potential-free contact of a relay. In this case, the corresponding contact of the relay via the external wiring to the control device 60, which should be in the context of the described embodiment is a central control device in the form of a signal box, are performed. In the case of a control device 60 in the form of a relay interlocking this can be done for further processing of the information signal IS integration into the relay interlocking while in the case of an electronic interlocking reading the information signal IS in the interlocking logic, for example via a digital I / O module can be done. As an alternative to the use of a potential-free contact of a relay, the transmission of the information signal IS from the trackside device 40 to the control device 60 can also take place, for example, by means of an opto-coupler.

As a result, the received information signal IS can be taken into account by the control device 60 as part of securing the travel path of the tracked vehicle 10. This relates in particular to a use of the information signal IS in a determination of a danger point distance and / or a slip path for the track-bound vehicle 10. The corresponding "reserve track lengths", which are colloquially also referred to uniformly as a slip path, are usually dependent on the respective permissible speed of a track-bound vehicle determines set or on the side of the circuit. As a rule, for track-bound vehicles above a certain permissible maximum speed, the presence of an on-board train control device is required Detecting this on-board train control device allows a corresponding adjustment of the danger point distance or the slip path for the respective tracked vehicle 10. Thus, it is possible with a corresponding fuse-technical design of the trackside device 40, in the case that for a track-bound vehicle 10 no Vehicle-mounted train control device 20 is detected to set a shorter slip path than in the event that such an on-board train control device 20 has been detected on the basis of the radiated signal.

In particular, in the case of mixed traffic of vehicles or trains with and without on-board train control devices 20, it is thus advantageously possible to start by default from short danger point distances or slip-roads for the rail-bound vehicles 10 running on the relevant route. Only in the event that the control device 60 on the basis of the received information signal IS is the information that the relevant track-bound vehicle 10 has a vehicle-side train control device 20 and thus is approved for higher speeds, can in the determination of the danger point distance or Sliding this way be set with a correspondingly longer length.

It should be noted that even a failure of the vehicle-side train control device 20 is technically uncritical security, since vehicle-side train control devices 20 are usually executed anyway according to safety requirement level SIL 4 and the track-bound vehicle 10 so that in case of failure of the vehicle side Train control device 20 responds to the safe side and accordingly runs at reduced speed. By forming the track-side device 40, the communication link 50 and the control device 60 according to this safety requirement level can thus be reliably excluded by setting a driveway with a too short slip path even in cases of failure.

Due to the automatic recognition of such track-bound vehicles 10, which are equipped with a vehicle-side train control device 20, an increase in the train sequence and overall optimization of the traffic flows is thus possible, for example, in the mixed mode between freight traffic and local traffic. Advantageously, this is done without relying on a non-secure process of the control technology, i. For example, a train running and train number tracking is used. Instead, the trackside device 40, i. by a component of the outdoor installation, an active detection of the vehicle-side train-influencing device 20, wherein the track-side device 40 either an example used in the context of the respective Zugbeeinflussungssystems, already existing or any other, possibly exclusively for the detection of the vehicle-side train control Device 20 may be provided component.

According to the above statements in connection with the described embodiment, the method according to the invention and the trackside device according to the invention thus result in considerable advantages in operational practice, the safety of the operation not being impaired or even increased in this case.

Furthermore, a comparatively cost-effective implementation is possible because in particular no changes on the vehicle side - neither hardware technology nor software technology - are required.
