Definitions
- the invention relates to a method for detecting and assigning stops in a train protection system according to the preamble of claim 1, in which a rail vehicle is issued a driving permit beyond at least one trackside signal and in which a state of the signal and an occupancy state of at least one on the signal monitored following track section and corresponding signal and Gieisüberwachungsmeldonne be generated.
- the invention relates to a holding case detection device according to the preamble of claim 10 for a train protection system, comprising: a first control center, which is adapted to give a rail vehicle a driving permission beyond at least one track-side signal; a second, at least functionally separate, second control center from the first control center configured to monitor a display state of the signal and an occupancy state of at least one track section following the signal and to generate corresponding signal and track monitoring messages.
- ECS L2 European Train Control System Level 2
- ETCS L2 radio block center - RBC which is responsible for the allocation of driving licenses (ETCS L2 so-called Movement authorities - MA)
- ETCS L2 so-called Movement authorities - MA the location of a rail vehicle on the route is only relative great inaccuracy known.
- the signal or the control device changes exactly in the Haltbegriff when the vehicle passes a defined sensor on or just behind the signal or indicator (rule or rule stop case), so that a subsequent vehicle can not enter the track section concerned.
- This passing of the signal or the license plate by the vehicle is detected by sensors of a tracking unit on the track and is thus very accurate with respect to the vehicle tip.
- the signal or the corresponding control device can also already change before passing the vehicle by a fault in the subsequent track in Halt, for example, if a corresponding change was triggered by an operator in another control center (interlocking) or a technical fault (accident or malfunction) , In this case, the vehicle must be brought to a stop as soon as possible beyond the signal or license plate despite a potentially existing movement permit (emergency brake).
- the system is not able to distinguish between rule and interference due to its own, inaccurate location.
- the invention has for its object to provide a method and an apparatus of the type mentioned in each case by which a train protection system, in- In particular, but without limitation, an ETCS L2 system, despite its own, inaccurate location of rail vehicles is able to distinguish between rule stop case and susceptible to interference and thus safely trigger the possibly required emergency brake.
- a method according to the invention for detecting and assigning stops in a train protection system in which a rail vehicle issued a driving permit beyond at least one signal on the range side in which a state of the signal and an occupancy state of at least one track section following the signal are monitored and corresponding signal and track monitoring messages are generated, characterized in that the signal and track monitoring messages are logically linked and depending on a result of the link between different stops is distinguished.
- the method includes in the context of signal monitoring also corresponding processes in a control unit, which gives the consent to pass on the "fictitious signal location" to the train control system.
- the state of the signal comprises both the display state of a stationary trackside signal and the logical state of the control device for a fictitious signal (flag).
- a signal monitoring message can therefore also be a license plate monitoring message within the meaning of the present invention.
- a stop-detection device for a train protection system, comprising: a first control center, which is adapted to a rail vehicle, a driving permission over at least one trackside To give out signal; a second, at least functionally separate from the first control center second control center, which is adapted to a display zuzu monitor the status of the signal and an occupancy state of at least one track section following the signal and generate corresponding signal and track monitoring messages; characterized by a linking unit adapted to logically link the signal and track monitoring messages and to indicate different stops depending on a result of the link.
- the corresponding control devices for a fictitious signal can also occur in the second control center according to the invention.
- the method according to the invention evaluates two messages from the second control center (e.g., an interlocking), which are basically intended for the first control center, which in particular communicates with the RBC, i. the center of the ETCS L2 can be identified: the messages concern 1) the change of the signal aspect of a track-side signal or the control device for a fictitious signal from "drive” to "stop” and 2) the occupancy of the first track section after the relevant signal. This makes it possible to distinguish between the rule case and the fault case.
- the second control center e.g., an interlocking
- the message component "is / was” expresses that the two messages are not necessarily in causally "correct” order at a location of their logical association, i.e. due to corresponding run times in the system. must arrive a corresponding link unit.
- the message "signal or the fictitious signal controller changes to stop” may arrive before the message "first section after signal busy” arrives, although the vehicle is entering this section, i. occupying the section was the actual cause of the signal change.
- a related development of the invention provides that when queuing a (signal) monitoring message indicating a stop display state of the signal or the control device for a fictitious signal during an adjustable waiting time for a track monitoring message, the occupancy of the signal following Track section, is being maintained.
- the messages to be evaluated of the first section behind the relevant signal are regularly accessible in the course of a special design of the second control center as a signal box in all common interlocking types.
- the present invention includes variants for evaluating the information contained in the messages in the second control center (e.g., interlocking), the first control center (e.g., RBC), or a separate unit.
- the second control center e.g., interlocking
- the first control center e.g., RBC
- Figure 1 is a schematic representation of a train protection system with an embodiment of the holding case detection device according to the invention.
- FIG. 2 shows a flow chart of an embodiment of the method according to the invention for detecting stops.
- FIG. 1 shows a simplified schematic illustration of a train protection system, in particular according to ETCS (European Train Control System) Level 2, with an embodiment of the stop-fall detection device 1 according to the invention.
- a first control center 2 in the form of a radio block center (RBC ), which is designed in particular to provide a rail vehicle 3, for example a train, with a travel permit MA (Movement Authority) for a ⁇ agreed to give purpose.
- RBC radio block center
- MA Movement Authority
- FIG. 1 further shows a travel path 4 (track) for the rail vehicle 3, which is divided by a number of signals (or fictitious signals or indicators) 5.1-5.4 into a number of (track) sections 4a-c wherein each one of the sections 4a-c may be subdivided into further train detection sections (subsections, not shown).
- Each of the signals 5.1-5.4 is assigned a locating unit 6.1-6.4 in the form of sensors arranged on the track (not shown).
- the locating units 6.1-6.4 serve to detect a passing of the rail vehicle 3 and provide an accurate locating result with respect to its tip (first axis).
- the relevant signal 5.1-5.4 is then switched over to "stop", which is referred to herein as a halt case display.
- stop which is referred to herein as a halt case display.
- the track section 4a-c which follows the relevant signal 5.1-5.4, for the entrance of another rail vehicle (not shown) is locked.
- the relevant subsection is a stop section or a stop fall prevention section and whether it has branches or not. If, for example, the rail vehicle 3 passes the signal 5.2 or the positioning unit 6.2, the signal 5.2 switches to "stop", and the track section 4b is occupied and thus blocked for further rail vehicles.
- the signals 5.1-5.4 and the locating units 6.1-6.4 are in signal communication with a second control center 7 in the form of an interlocking, which is at least functionally separated from the first control center 2.
- the second control center 7 is designed to monitor a respective display state of the signals or identifiers 5.1-5.4 and an occupancy state of the track section 4a-c following the respective signal and its further subdivisions.
- the signals / indicator 5.1-5.4 from the second control center 7 also manually, ie switch on the initiative of an operator, for example, to selectively stop the rail vehicle 3 in the presence of an accident.
- the second control center 7 generates in ⁇ ⁇
- the linking unit 8 is designed for logically ANDing the signal and track monitoring messages FÜ, GFM. It also contains a time delay unit 9, whose importance will be discussed in more detail below.
- the linking unit 8 is also designed to indicate different stopping situations as a function of a result of the linking of the signal and track monitoring messages FÜ, GFM and is for this purpose in operative connection with the RBC 2.
- the RBC 2 has given the rail vehicle 3 a radio movement MA via the signals / license plates 5.2-5.4.
- the respective signals / identifiers 5.2-5.4 are "on the move" when the rail vehicle 3 arrives, they may be run over by the rail vehicle 3, whereby the driving speed is likewise predetermined by the movement authority MA.
- the behavior outlined above is a standard case in which the Movement Authority MA can continue to exist, that is, does not have to be revoked.
- a signal / indicator for example, the signal / indicator 5.2
- the RBC 2 can not reliably recognize this fact due to the location inaccuracy detected in certain train control systems, such as ETCS Level 2, with respect to a current location of the rail vehicle 3.
- the second control center (signal box) 7 provide the signal and track monitoring g FÜ, GFM meidungen initially and also transmits to the operation unit 8, in which they are subjected to a logical AND operation, whereby one can distinguish between different stop cases.
- the stop display state of the relevant signal / flag for example, the signal / indicator 5.2 or an occupancy of the following on the signal / plate track section corresponding So the track section 4b, indicate this is interpreted as a rule stop case and displayed to the RBC 2 by means of a corresponding detection signal.
- the RBC 2 does not arrange for a repossession of the Movement Authority MA.
- the above-explained signal monitoring message FÜ of the relevant signal / indicator for example the signal / indicator 5.2, but without a track monitoring message GFM at the same time, occupying an occupancy of the track section following the signal , ie of the track section 4b or one of its subsections, this is interpreted as an interference condition and displayed to the RBC 2 by means of a corresponding detection signal.
- the RBC 2 causes accordingly by radio the withdrawal of the Movement Authority MA, so that the rail vehicle 3 at the signal / plate 5.2 stops or is stopped.
- the positioning accuracy of the locating 6.1-6.4 is exploited according to the invention to be able to distinguish despite a system inherent positioning inaccuracies, for example, trackside at ETCS Level 2, safely between rule case and sturgeon.
- a signal monitoring message FÜ may arrive earlier at the second control center 7 or the linking unit 8 than the causally earlier associated track monitoring message GFM.
- Linking unit 8 on the aforementioned time delay unit 9. is designed to cause the linking unit 8 to wait for a track monitoring message GFM before the link during an adjustable waiting time when pending a signal monitoring message FÜ, indicating a stop indication state of a signal / flag, for example the signal / flag 5.2 indicating an occupancy of the on the signal / indicator, for example, the signal / indicator 5.2, the following track section 4b or one of its subsections.
- the linkage according to the invention of the signal and track monitoring messages in the linking unit 8 takes place in the described case not immediately after receiving one of the two messages, but only after elapse of an adjustable waiting time, so that the mentioned signal propagation times can be considered or compensated.
- the length of the waiting period can not be specified in general, but depends on the specific circumstances of the train control system under consideration.
- the first and second control centers 2, 7 as well as the linking unit 8 are each arranged spatially separated from one another.
- the linking unit 8 it is also possible for the linking unit 8 to be arranged or contained in the first or in the second control center, that is to say the RBC 2 or the signal box 7.
- the first control center 2 and the second control center 7 may also physically coincide, as long as the described functional realities continue to be realized.
- Fig. 2 shows a timing diagram of an embodiment of the inventive method for detecting and assigning stops in a train protection system, in particular according to the illustration in Fig. 1.
- the phases I-III defined below are distinguishable, which alternatively also as separate methods can be represented: I. Movement Authority is granted; II. First track section behind the signal / indicator is occupied; and III. The driving position of the signal / indicator is canceled.
- the method begins with step 100.
- a rail vehicle such as a train, is given a movement authority beyond at least one trackside signal.
- Steps 100-104 form the above-mentioned first phase (I) -
- a track monitoring message is generated which indicates that the first track section located behind a specific signal is occupied. This is usually caused by the fact that the rail vehicle has passed the relevant signal or an associated locating unit.
- step 112 a signal monitoring message is generated indicating that the above signal has changed from "drive” to "stop".
- step 120 a check of the track occupancy state for the first track section behind the relevant signal takes place in step 120. If this is occupied (j), the method continues with step 116. Otherwise, it is waited in step 122 during an adjustable, system-dependent waiting or delay time - as already explained with reference to FIG. described in detail - and then checked in step 124, the track occupancy state of the first track section after the signal in question again. If this is now reported as busy (j), then the method is continued with step 116. Otherwise, in step 126, the movement authority is withdrawn by the corresponding control center (RBC). The method then ends with steps 116 and 118. Steps 112-126 form the above-mentioned third phase (III).
