Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The conversion method between the DTC and CBTC control levels of the present invention is described below with reference to fig. 1 to 3.
As shown in fig. 1, the conversion method between DTC and CBTC control levels includes: step 110, step 120 and step 130.
in this step, the train is urban rail transit, including but not limited to light rail, city rail, or subway, etc.
The position information of the vehicle confidence position is used to characterize the actual position of the vehicle confidence position of the train in the track.
It should be noted that, in the running process of the train, the running track is formed by connecting a plurality of guide rails end to end, and the plurality of guide rails include: a common guide rail and a transition rail.
Wherein the switching track is a track for performing control level switching.
The control levels include: a Digital Track Circuit Control (DTC) level and a wireless Communication Based Train automation Control (CBTC) level.
Among them, CTC is CBTC control hierarchy.
During the actual operation of the train, the conversion of the control level is involved, including the conversion from the CTC to the DTC and the conversion from the DTC to the CTC.
Step 120, when the vehicle confidence position enters a target switching track, under the condition that target movement authorization information is received and the current control mode of the train is a first control level, converting the first control level into a target control level, wherein the target movement authorization information is movement authorization information of the target control level;
in this step, the current control mode includes, but is not limited to: a DTC control level, a CTC control level, and an RM mode (speed-limiting manual driving mode).
The target transition track includes: a DTC to CTC control rank transition track and a CTC to DTC control rank transition track.
The first control level is the current control level of the train, and the target control level is the control level of planned switching of the train.
The first control level and the target control level are relative control levels.
Under the condition that the first control level is a DTC control level, the target control level is a CTC control level; in the case where the first control level is the CTC control level, the target control level is then the DTC control level.
The target mobile authorization information is mobile authorization information of a target control level, for example, in the case that the target control level is a DTC control level, the target mobile authorization information is mobile authorization information under the DTC control level; and under the condition that the target control level is the CTC control level, the target mobile authorization information is the mobile authorization information under the CTC control level.
In the actual execution process, under the condition that the current control mode of the train is the first control level, the position information of the vehicle confidence position of the train is obtained in real time, whether the vehicle confidence position enters a target switching track or not is judged, and once the vehicle confidence position is determined to enter the target switching track and the target movement authorization information is received, the train is immediately controlled to be switched into the target control level.
The inventor finds that in the research and development process, as the DTC system needs to establish insulation section positioning in advance, and the CTC system needs to establish transponder positioning in advance, in the related technology, degradation processing is involved when control level switching is carried out, and parking conversion is often needed, so that the operation efficiency of a train is influenced.
In the application, the process of stopping and degrading is abandoned, so that the system conversion is directly completed in the running process of the train, namely the first control level is directly converted into the target control level without stopping, and the operation efficiency of the train is effectively improved.
In addition, the mark at the start of train switching is changed from the original parking window (the parking window is generally in the middle position of the switching track) to the mark at the start of train switching, and the switching is started just after the vehicle confidence position enters the system switching track, so that sufficient time can be reserved for the switching process, and the switching success rate is improved.
In other embodiments, when the vehicle confidence position enters the target switching track, under the condition that the target movement authorization information is not received and the current control mode of the train is the first control level, controlling the train to keep running at the first control level;
the train is controlled to stop at the target switch rail and the train is controlled to downgrade to the RM mode.
In this embodiment, in the case where the current control mode of the train is the first control level, when the target movement authorization information is not received, the control train keeps the first control level running and is downgraded to the RM mode after the stop.
In this step, the conversion result includes conversion success and conversion failure.
In the actual implementation, the conversion result may be determined based on the actual conversion condition of the train.
It can be understood that in the case where the train is converted from the first control level to the target control level, the conversion may be considered to be successful; and in case that the train fails to switch to the target control level, the switch may be considered to fail.
If the train maintains the first control level operation or is degraded to the RM mode after stopping, the transition is considered to have failed.
In some embodiments, after determining the conversion result, the conversion result may also be output for reference by the user.
In some embodiments, step 130 may include:
acquiring a conversion duration corresponding to the conversion of the first control level into the target control level;
and under the condition that the conversion time length exceeds the target time length, determining the conversion result as conversion failure.
In this embodiment, the transition duration is the actual duration taken to transition the train from the first control level to the target control level.
The target duration may be determined based on the track length and the highest speed limit at which the train is stopped at the current station.
Comparing the conversion duration with the target duration, and considering the conversion result under the condition that the conversion duration does not exceed the target duration; and in the case that the conversion time length exceeds the target time length, the conversion is considered to fail.
According to the conversion method between the DTC and the CBTC control level, which is provided by the embodiment of the application, the conversion is restrained by controlling the conversion time length corresponding to the conversion from the first control level to the target control level within the target time length, so that the safety and the reliability in the conversion process can be improved.
In some embodiments, step 130 may include:
after the first control level is converted into a target control level, determining a track where the train is located currently;
in the case where the track is not on the target switching track, the switching result is determined to be a switching failure.
In this embodiment, it is determined whether the train is still on the on-track switching track (i.e., the target switching track) when the system switching is completed, and if so, the switching result is considered; if not, the conversion is deemed to have failed.
That is, it is necessary to ensure that the train is always on the target switch track during the switching process.
According to the conversion method between the DTC and the CBTC control grade, the train is controlled to be always on the target conversion rail in the conversion process to restrict the conversion, and the safety and the reliability in the conversion process can be improved.
In the actual implementation process, the determination method provided by the above embodiments may be integrated to determine the conversion result, so as to ensure the safety of train conversion.
According to the conversion method between the DTC and the CBTC control grade, under the condition of normal conversion, when the vehicle confidence position of the train enters the target conversion track, the train is controlled to be converted from the first control grade to the target control grade, the conversion between the DTC and the CTC control grade can be realized without stopping the train, sufficient time can be reserved for the conversion process, the train operation efficiency is improved, and meanwhile, the safety of the conversion process can be effectively ensured; in addition, the method is beneficial to improving the operation efficiency of the multi-system compatible signal system, does not influence the operation of the existing system, and realizes non-inductive reconstruction.
In some embodiments, after step 110, the method may further comprise:
when the train enters a target switching rail, target movement authorization information is not received, and the current control mode of the train is the RM mode, controlling the train to keep running in the RM mode;
and when the train has the positioning information corresponding to the target control level and receives the target movement authorization information in the running process of the train, switching the train from the RM mode to the target control level.
In this embodiment, the positioning information includes DTC positioning and CTC positioning, where the positioning information corresponding to the DTC control level is DTC positioning, and the positioning information corresponding to the CTC control level is CTC positioning.
Under the condition that the train operates in an RM mode, when the train still keeps the RM mode after entering a target switching track and does not receive target movement authorization information, whether the train has positioning information corresponding to a target control level needs to be further judged.
And under the condition that the train has the positioning information corresponding to the target control level, continuously acquiring the target movement authorization information in the running process of the train, and once the target movement authorization information is acquired, switching the train from the RM mode to the target control level.
In other embodiments, after controlling the train to maintain the RM mode of operation, the method may further comprise:
when the train has positioning information corresponding to the target control level and the train does not receive the target movement authorization information in the running process, controlling the train to keep running in an RM mode;
and switching the train from the RM mode to the target control level when the train receives the target movement authorization information on a track next to the target switching track.
In this embodiment, when the train operates in the RM mode, when the train still keeps the RM mode after entering the target switching track and does not receive the target movement authorization information, it needs to further determine whether the train has the positioning information corresponding to the target control level.
And under the condition that the train has the positioning information corresponding to the target control level, continuously acquiring the target moving authorization information in the running process of the train.
And in the case that the target moving authorization information can not be acquired all the time, controlling the train to continuously keep the RM mode operation.
And continuously acquiring the target movement authorization information after the train enters the next track, and once the target movement authorization information is acquired, switching the train from the RM mode to the target control level.
According to the conversion method between the DTC and the CBTC control grade, provided by the embodiment of the application, under the condition of abnormal conversion, when the train receives the target movement authorization information, the train is controlled to be directly upgraded from the RM mode to the target control grade, the conversion of the control grade can be realized without stopping the train, and the running speed and the operation efficiency of the train are obviously improved.
The following specifically describes an implementation of the present application from four perspectives, respectively, with reference to fig. 2 and 3.
1. Normal transition scenario from CTC to DTC
As shown in fig. 3, in the normal transition scenario of the CTC to DTC, the target transition track is the CTC to DTC control level transition track.
The current control mode of the train is the CTC control level, i.e., the first control level is the CTC control level.
The target control level is a DTC control level.
The train can receive the ground digital track circuit information before entering the target switching track, and after receiving the new carrier frequency through the track circuit boundary, the train establishes track positioning.
After the vehicle-mounted ATP (automatic train protection) on the train enters a target switching track at a CTC control level (CM/AM mode), whether target movement authorization information is received or not is judged.
The CM is in an automatic protection mode, a signal system carries out safety protection, and a driver controls the traction and the braking of the train;
and the AM is an automatic driving mode, a signal system carries out safety protection, and the signal system controls the traction and the braking of the train.
The target moving authorization information is digital track circuit moving authorization information from a system conversion track, namely authorization information under a DTC.
In the event that the train receives the target move grant information and the move grant is sufficiently long (e.g., exceeds a first threshold), the train is immediately converted from the CTC control level to the DTC control level when the vehicle confidence location enters the target switch track.
And after the current control mode of the train is converted into the target control level, determining that the conversion result is successful.
For example, a prompt "train has switched to DTC" may be displayed in the HMI (human machine interface) lower left prompt bar to complete the switch.
For another example, it is also possible to hold the original mode information in the train driving mode area on the HMI and display the control level as the DTC.
Finally, the train starts to initiate a logout to a ZC (zone manager).
In other embodiments, in the case that the train does not receive the target movement authorization information, the on-board ATP is controlled to keep the CTC control level running.
And normally stops the vehicle on the mode-making switching track (i.e., the target switching track), then is downgraded to the RM mode, outputs the emergency brake, and determines that the switching result is a switching failure.
For example, "control level switching failure" may be output on the HMI.
2. CTC to DTC exception handoff scenario
With continued reference to FIG. 3, in a CTC to DTC exception switch scenario, the target switch track is the CTC to DTC control level switch track.
The current control mode of the train may be an RM mode.
The target control level is a DTC control level.
The target moving authorization information is the moving authorization information of the digital track circuit from the system conversion track.
In a CTC to DTC abnormal switching scenario, the train is downgraded to RM mode before or after entering a target switch track.
It will be appreciated that in actual implementation, the CTC control level may or may not be restored after the train enters the target switch track.
In some embodiments, in the case that the train can be restored to the CTC control level from the RM mode after entering the target transition track, the train is controlled to be restored to the CTC control level from the RM mode and to be transitioned to the DTC control level from the CTC control level, and the specific transition logic is consistent with a normal transition scenario from the CTC to the DTC, which is not described herein again.
In other embodiments, in the event that the train cannot be restored to the CTC control level after entering the target switch track, it is determined whether target movement authorization information is received.
And in the case that the train receives the target movement authorization information, directly upgrading the train from the RM mode to a DTC control level.
If the CBTC system positioning is provided, the position report is consistent with a normal switching scene.
In still other embodiments, when the train cannot be restored to the CTC control level after entering the target switching track and the train does not receive the target movement authorization information, the train is controlled to keep the RM mode operation, whether the train has DTC positioning or not is judged, and whether the train receives the target movement authorization information or not is continuously judged.
And under the condition that the train has DTC positioning and receives target movement authorization information in the running process, the train is controlled to be directly upgraded to the DTC control level from the RM mode.
And when the DTC is positioned on the train and the target movement authorization information is not received in the running process, controlling the train to keep running in an RM mode, and continuously judging whether the train receives the target movement authorization information.
And after the train enters the next track and acquires the target movement authorization information, directly upgrading the train to a DTC control level by the RM mode.
In some embodiments, after the train is converted into the DTC control level, the train is degraded into the RM mode for some reasons, and then the train is directly converted into the DTC control level instead of the CTC level after the condition of upgrading the DTC control level is met, so that the train is prevented from being stopped and converted, and the conversion efficiency of the train is improved, so that the operation efficiency is improved.
In some embodiments, the train passes the target switching track directly after the train does not complete switching in the target switching track, and the vehicle-mounted ATP applies emergency brake stop and loses location when judging that the maximum safe front position of the train passes the target switching track.
Or, the train operates in an RM mode and is converted into a DTC control level after receiving the target movement authorization information.
In some embodiments, the train is switched from cut mode to active mode at the target switch track, the train is controlled to operate in RM mode, DTC location is established on the next track and switched to DTC control level after receiving the target move authorization message.
3. DTC to CTC Normal switch scenarios
As shown in fig. 2, in the DTC to CTC normal switch scenario, the target switch track is the DTC to CTC control level switch track.
The current control mode of the train is the DTC control level, i.e., the first control level is the DTC control level.
The target control level is the CTC control level.
The target mobile authorization information is CTC down mobile authorization sent by the ZC.
In a normal switching scene from a DTC to a CTC, before a train enters a target switching track, receiving transponder information and establishing transponder positioning, and under the condition that a valid ZC exists in an electronic map, initiating registration to the ZC and establishing communication with the ZC.
And after the distance between the train and the axle is less than a minimum train length in the front rail of the target switching rail, the ZC finishes head screening and calculates the movement authorization of the vehicle-mounted ATP.
After the train enters a target switching track at a DTC level (AM/CM mode), whether the train receives target movement authorization information is judged.
And under the condition that the train receives the target moving authorization information, controlling the train to be converted into the CTC control grade from the DTC control grade when the vehicle confidence position enters the target conversion track.
And then determining a conversion result based on the conversion time length and the track position of the train after conversion.
For example, when the train is converted from the DTC control level to the CTC control level and the conversion time length and the conversion position both meet the requirements, the original mode information is kept in the train driving mode area on the HMI, the control level is displayed as the CTC, and meanwhile, a prompt that the train is converted to the CTC is displayed in a prompt column at the left lower part of the HMI, so that the switching is completed.
In other embodiments, in the event that the train does not receive the target movement authorization information, the train is controlled to normally stop within the parking window at the DTC control level, downgrade to the RM mode, and output emergency braking.
And then determining that the conversion result is conversion failure.
For example, "control level switch failure" may be prompted on the HMI.
4. DTC to CTC exception switching scenarios
With continued reference to FIG. 2, in the DTC to CTC exception switch scenario, the target switch track is the DTC to CTC control level switch track.
The current control mode of the train may be an RM mode.
The target control level is the CTC control level.
The target mobile authorization information is CTC down mobile authorization sent by the ZC.
In the actual implementation process, if the train is degraded to the RM mode before entering the target switch track or after entering the target switch track, it is necessary to determine whether the train can be recovered to the DTC control level.
Under the condition that the train can be recovered to the DTC control level after entering the target switching track, the subsequent switching logic is consistent with the normal switching scene from the DTC to the CTC, and details are not repeated herein.
And under the condition that the train can not be recovered to the DTC control level after entering the target switching track, controlling the train to firstly keep the RM mode operation, and then judging whether the train receives the target movement authorization information.
And under the condition of obtaining the target mobile authorization information, directly converting the control train from the RM mode into a CTC control level.
And under the condition that the target movement authorization information is not obtained, continuously controlling the train to run in an RM mode, further judging whether the train has CTC positioning, and continuously judging whether the train receives the target movement authorization information.
And under the condition that the train has CTC positioning and target mobile authorization information is received, controlling the train to be directly converted into a CTC control level from an RM mode.
And when the train has CTC positioning and does not receive the target mobile authorization information, controlling the train to continuously run in an RM mode, and after the train enters the next track, once the target mobile authorization information is acquired, converting the RM mode into a CTC control level.
In some embodiments, in the case where the train is downgraded to the RM mode for some reason after the transition to the CTC control level, the transition to the CTC control level is made directly after the condition for upgrading the CTC control level is satisfied without the transition to the DTC level to avoid a stop, thereby improving the operation efficiency.
In some embodiments, in the case where the train is not stopped at the target switch rail and directly crosses the target switch rail at the DTC control level, the on-board ATP applies the emergency brake stop and loses location when it is determined that the maximum safe front position of the train crosses the target switch rail.
In some embodiments, the train is switched from the cut-out mode to the active mode at the target switching track, the train operates in the RM mode, and the CTC control level may be switched after the CTC location is established and the target move authorization information is received.
The conversion device between the DTC and the CBTC control level provided by the present invention is described below, and the conversion device between the DTC and the CBTC control level described below and the conversion method between the DTC and the CBTC control level described above can be referred to each other.
