Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a train transfer method and a train transfer system.
Background
In the design of a track traffic line, a plurality of stations in one line are divided into Zone Controller (ZC) concentrated zones, the boundary of two ZC concentrated zones is called a 'handover boundary', a part of a track Zone on the left side of the handover boundary point is generally used as a Zone in an overlapped Zone of a local ZC on the left side, a part of a track Zone on the right side of the handover boundary point is used as a Zone in an overlapped Zone of a local ZC on the right side, and according to data configuration, the handover ZC can identify a Zone in the overlapped Zone of the taking-over ZC, and the taking-over ZC can identify a Zone in the overlapped Zone of the taking-over ZC. And each ZC with the same handover boundary periodically transmits the station and field information of physical zones, turnouts, station delay states, rail zone train sequencing and the like of which the overlapped areas belong to the respective jurisdiction range to each other periodically. The train handover diagram is shown in fig. 1.
The schematic diagram of the train handover process is shown in fig. 2, wherein a train is located in the handover ZC overlapping area and is performing a handover across zones to the takeover ZC through the handover ZC overlapping area. In order to improve the efficiency of train handover and takeover, when the maximum safe front end position of the train enters the overlapping area range of the handover ZC, the train sends the information of the handover train to the takeover ZC; when the moving Authorization (Movement Authorization) MA1 of the train reaches the transfer boundary, transferring the information of the transfer state of the ZC augmented transmission train, and starting the train transfer process at the moment; the takeover ZC calculates MA2 for the train from a transfer boundary according to the train information (including a train position report), the train transfer state information and the station yard information sent by the transfer ZC, and sends the MA2 information to the transfer ZC through the train transfer state information; after receiving the MA2 information, the handover ZC splices the MA1 information and the MA2 information to form new MA information and sends the new MA information to the train, and the train can smoothly and seamlessly cross the handover boundary without speed reduction and enter the jurisdiction range of the handover ZC, thereby realizing the functions of train handover and handover of moving block tracking.
Based on moving block tracing train in the process of cross-district handover operation, the handover ZC sends handover train information to the takeover ZC, if the train location report information sent by the handover ZC does not belong to the jurisdiction of the taken over ZC, the takeover ZC cannot identify the train location report information, resulting in the problem that the train cannot normally run in cross-district, as shown in fig. 3: the section where the train tail is located is SEG05, and does not belong to the handover ZC overlapping area (the track sections contained in the handover ZC overlapping area are SEG01 and SEG 02); at this time, if the handover ZC sends a true location report to the takeover ZC, the takeover ZC discards the handover train information because it cannot recognize the SEG05 (the takeover ZC can recognize the SEG01 and the SEG 02) and finally causes the handover ZC and the takeover ZC to interrupt communications. Similarly, when the train passes through the handover boundary and is driven away from the boundary of the overlapping zone of the takeover ZC, the track section where the maximum safe front end of the train is located is SEG06 and cannot be identified by the handover ZC (the handover ZC can only identify SEG03 and SEG 04), so that the handover ZC determines that the handover train information sent by the takeover ZC is illegal, the communication between the handover ZC and the takeover ZC is interrupted, and the normal handover and takeover across zones of the train are directly influenced.

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 Train handover method provided by the invention can realize the functions of trans-zone handover and takeover of a Train when the next ZC of a Communication Based Train Control (CBTC) system comprises a plurality of adjacent ZCs, so that the Train can smoothly and seamlessly cross over a handover boundary without reducing the speed and enter the jurisdiction range of the takeover ZCs, and the method is specifically realized as follows:

200, sending second train handover information to a first ZC under the condition that the train safety envelope meets a second preset condition;
the train handover information at least comprises train moving authorization, train handover state information, a train position report and station yard information, wherein the station yard information at least comprises a physical section, a turnout, a station yard delay state and track section train sequencing in the jurisdiction range of the second ZC;
the first ZC and the second ZC are adjacent.
It is noted that the execution subject of the above method may be the second ZC.
Alternatively, referring to fig. 5, the handover ZC overlap region (i.e., the second ZC overlap region) and the adjacent ZC overlap region (i.e., the first ZC overlap region) are divided according to handover boundary points of the respective terrestrial ZC control regions, and overlap region attributes to which the track sections belong are specified: a handover ZC overlap zone attribute and an adjacent ZC overlap zone attribute.
It should be noted that the handover ZC and the adjacent ZC are opposite, as shown in fig. 6, where ZC1 is the handover ZC for ZC1, ZC2 is its adjacent ZC, the overlapping area of ZC1 is the handover ZC overlapping area, and includes track sections SEG01 and SEG02, and the adjacent ZC overlapping area of ZC1 is the ZC2 overlapping area, and includes track sections SEG03 and SEG04; for ZC2, ZC2 is a handover ZC, then ZC1 is its adjacent ZC, the overlapping area of ZC2 is a handover ZC overlapping area including track sections SEG03 and SEG04, and the adjacent ZC overlapping area of ZC2 is a ZC1 overlapping area including track sections SEG01 and SEG02.
If the handover ZC (i.e., the second ZC) considers that any part of the train safety envelope is within the second ZC overlapping zone jurisdiction, this second ZC should send handover train information of the train to all its adjacent first ZCs, and the schematic diagram of the train safety envelope is shown in fig. 7.
In one embodiment, in case it is determined that the train safety envelope satisfies a first preset condition, first train handover information of a train (handover train) is transmitted to the first zone controller ZC.
In one embodiment, the first preset condition may specifically include that the train minimum safe front position, the train maximum safe rear position and the train minimum safe rear position in the train safety envelope are all located in the second ZC overlapping area; the second preset condition comprises a first judgment condition, a second judgment condition and a third judgment condition.
And sending second train handover information to the first ZC under the condition that the second ZC determines that the train safety envelope meets a second preset condition.

Further, in an embodiment, step 200 may specifically include:
step 2001, in case that it is determined that the train safety envelope satisfies the first determination condition, truncating and correcting the train tail position in the train position report, truncating the train maximum safety rear end position and the train minimum safety rear end position in the train position report to a first ZC overlap area boundary point or a second ZC overlap area boundary point, and correcting the train maximum safety rear end position and the train minimum safety rear end position;
step 2002, determining second train handover information according to the corrected train tail position, the corrected train maximum safe rear end position and the corrected train minimum safe rear end position;
step 2003, transmitting second train handover information to the first ZC;
wherein the first judgment condition includes: the maximum safe front end position of the train is positioned in the second ZC overlapping area, the minimum safe rear end position of the train is not positioned in the second ZC overlapping area, and the minimum safe rear end position of the train is not positioned in the first ZC overlapping area;
the corrected train tail position is located in a track section in the second ZC jurisdiction or a track section in the first ZC jurisdiction.
Alternatively, referring to fig. 5, if the maximum safe front end position of the train is located in the second ZC overlapping zone, the minimum safe rear end position of the train is not located in the second ZC overlapping zone, and the minimum safe rear end position of the train is not located in the first ZC overlapping zone, i.e., the train has not completely entered the handover ZC overlapping zone when performing handover between zones (the same applies to some atypical special scenarios such as when the train travels from the adjacent ZC to the handover ZC and the train head has traveled over the handover boundary but the train tail has not entered the adjacent ZC overlapping zone), the train position report in the handover train information is to truncate the train tail position (the modified train tail position is located in the track section in the second ZC jurisdiction or in the track section in the first ZC jurisdiction), truncate the train maximum safe rear end position and the train minimum safe rear end position to the first overlap ZC zone boundary point or the second ZC zone boundary point, and then transmit the train position report including the modified train position (i.e., the second train information) to the adjacent ZC overlapping zone boundary point or the handover as shown in fig. 8.
The train transfer method provided by the invention elaborates the algorithm of how to correct and cut off the position report information (train tail position, train maximum safe rear end position and train minimum safe rear end position) sent by the ground ZC in the transfer train information in the transfer train transfer and takeover process of the train cross-zone in the CBTC system in detail, makes up the blank of the implementation details of the position report cut-off processing technology under the train cross-zone transfer and takeover functions in the CBTC system, and realizes the functions of train cross-zone transfer and takeover.
Further, in an embodiment, step 200 may further specifically include:
step 2004, under the condition that the train safety envelope is determined to meet the second judgment condition, correcting the actual position of the train in the train position report according to the train minimum safety front end position, the train maximum safety rear end position and the train minimum safety rear end position in the train safety envelope;
step 2005, determining second train handover information according to the corrected actual train position;
step 2006, transmitting second train handover information to the first ZC;
wherein the second determination condition includes: and under the condition that the maximum safe front end position of the train is positioned in the second ZC overlapping area, the minimum safe rear end position of the train is positioned in the second ZC overlapping area or the first ZC overlapping area.
Optionally, with continued reference to fig. 5, if the maximum safe front end position of the train is located in the second ZC overlapping area and the minimum safe rear end position of the train is located in the second ZC overlapping area or the first ZC overlapping area of the minimum safe rear end position of the train, the actual position of the train in the train position report is modified according to the minimum safe front end position, the maximum safe front end position, the minimum safe rear end position, and the minimum safe rear end position of the train in the train safety envelope, and the train position report in the second handover train information is sent to the adjacent ZC (first ZC) according to the actual position of the train.
As shown in fig. 9, in one embodiment, when the train safety envelope is completely located within the overlap area of ZC1, the train position report (train maximum safety front position, train maximum safety rear position, and train minimum safety rear position) transmitted by ZC1 to ZC2 is the position of the actual train, ZC2 does not transmit the second handover train information to ZC 1; when the train safety envelope is completely located within the ZC2 overlap region, the train position report (position information of four ends) transmitted by the ZC2 to the ZC1 is the position of an actual train, and at this time the ZC1 does not transmit handover train information to the ZC 2.
As shown in fig. 10, in one embodiment, when the train is located on the handover boundary, the above-described second determination condition is satisfied, and both ZC1 and ZC2 transmit second handover train information to the other, and the train position reports in the transmitted second handover train information are both the location points where the actual positions of the trains are located.
The train transfer method elaborates the algorithm of how to correct and cut off the position report information (the actual position of the train) sent by the ground ZC in the transfer train information in the transfer handover takeover process of the train crossing the district in the CBTC system in detail, makes up the blank of the implementation details of the position report cutting processing technology under the functions of the transfer handover and takeover of the train crossing the district in the CBTC system, and realizes the functions of the transfer handover and takeover of the train crossing the district.
Further, in an embodiment, step 200 may further specifically include:
2007, under the condition that the train safety envelope meets a third judgment condition, performing truncation correction on the train head position in the train position report, and truncating the train maximum safety front end position and the train minimum safety front end position in the train position report to a first ZC overlapping region boundary point or a second ZC overlapping region boundary point, and correcting the train maximum safety front end position and the train minimum safety front end position;
step 2008, determining second train handover information according to the corrected train head position, the corrected train maximum safe front end position and the corrected train minimum safe front end position;
step 2009, sending a second train handover information to the first ZC;
wherein the third determination condition includes: a first sub-judgment condition and a second sub-judgment condition;
the first sub-judgment condition includes: the maximum safe front end position of the train is not positioned in the second ZC overlapping area, and the minimum safe rear end position of the train is positioned in the second ZC overlapping area;
the second sub-judgment condition includes: the maximum safe front end position of the train is not positioned in the second ZC overlapping region, the minimum safe rear end position of the train is not positioned in the second ZC overlapping region, and the minimum safe rear end position of the train is positioned in the first ZC overlapping region;
the corrected train head position is located in a track section in the second ZC jurisdiction or a track section in the first ZC jurisdiction.
Alternatively, with continued reference to fig. 5, if the maximum safe front end position of the train is not located in the second ZC overlapping zone and the minimum safe rear end position of the train is located in the second ZC overlapping zone, that is, the train normally exits from the overlapping zone, the train position report in the second handover train information needs to modify the train head position by truncation (the modified train head position is located in a track section in the second ZC jurisdiction or a track section in the first ZC jurisdiction), truncate the maximum safe front end position of the train and the minimum safe front end position of the train to a first ZC overlapping zone boundary point or a second ZC overlapping zone boundary, and then send the second train information including the modified train position report to the adjacent ZC (i.e., the first ZC), as shown in fig. 11 below.
If the maximum safe front end position of the train is not positioned in the second ZC overlapping area, the minimum safe rear end position of the train is not positioned in the second ZC overlapping area and the minimum safe rear end position of the train is positioned in the first ZC overlapping area, the scene is also an atypical special scene that the train normally runs out of the overlapping area, namely the overlapping area is short in range and the train is long in length, the atypical scene occurs. The train position report in the second handover train information also needs to truncate and correct the train head position (the corrected train head position is located in a track section in the second ZC jurisdiction or a track section in the first ZC jurisdiction), truncate the maximum safe front end position and the minimum safe front end position of the train to the first ZC overlapping zone boundary point or the second ZC overlapping zone boundary, and then send the second train handover information including the corrected train position report to the adjacent ZCs (i.e., the first ZCs), as shown in fig. 12.
The train transfer method provided by the invention elaborates the algorithm of how to correct and cut off the position report information (train head position, train maximum safe front end position and train minimum safe front end position) sent by the ground ZC in the transfer train information in the transfer train transfer and takeover process in the CBTC system in detail, makes up the blank of the implementation details of the position report cut-off processing technology under the train transfer and takeover functions in the CBTC system, and realizes the functions of train transfer and takeover in a cross-district manner.
Further, in an embodiment, the method may further specifically include:
under the condition that the train safety envelope meets a third preset condition, not sending first train handover information to the first ZC;
wherein the third preset condition comprises: the train maximum safe front end position is not located in the second ZC overlapping area, the train minimum safe rear end position is not located in the second ZC overlapping area, and the train minimum safe rear end position is not located in the first ZC overlapping area.
Optionally, with reference to fig. 5, if the maximum safe front end position of the train is not located in the second ZC overlapping zone, the minimum safe rear end position of the train is not located in the second ZC overlapping zone, and the minimum safe rear end position of the train is not located in the first ZC overlapping zone, it is considered that the train position is abnormal or completely exits from the takeover ZC (i.e., the first ZC) overlapping zone, and at this time, the second ZC should not send the first train handover information to the first ZC.
The takeover ZC (namely the first ZC) judges whether to start or end a handover takeover process according to the handover train information sent by the handover ZC and by combining the train position report information, and finishes the functions of trans-regional handover and takeover of the train under the tracking of moving block.
In one embodiment, the location report truncation processing algorithm is also applicable to a scenario where a second ZC comprises a plurality of adjacent first ZCs, as shown in FIG. 13: ZC1 (the second ZC) contains two adjacent ZCs: ZC2 and ZC3 (i.e. a first ZC), wherein an adjacent ZC overlapping region of ZC2 and an adjacent ZC overlapping region of ZC3 overlap, when a train enters ZC1 across a handover boundary from ZC2, ZC1 determines that a train maximum safe front end position is located in the ZC1 overlapping region and a train minimum safe rear end position is not located in the ZC1 overlapping region, and at this time a train rear end position is located in the ZC2 overlapping region but not located in the ZC3 overlapping region; the information of the handover train sent by ZC1 to ZC2 and the information of the handover train sent by ZC2 to ZC1 are sent according to the actual position of the train; and in the transfer train information sent by ZC1 to ZC3, the train tail position of the train position report is cut off to the boundary point of the overlapped area of ZC1 or the boundary of the overlapped area of ZC3, and at the moment, the communication interruption between ZC3 and ZC1 caused by the fact that the ZC3 receives the transfer train information sent by ZC1 can not be caused because the train position report can not be identified.
The train transfer method provided by the invention elaborates the algorithm of how to correct and cut the position report information in the transfer train information sent by the ground ZC in the process of transferring and taking over the train across zones in the CBTC system in detail, fills up the gap of the implementation details of the position report cutting-off processing technology under the function of transferring and taking over the train across zones in the CBTC system, has expandability, and is also applicable to the method for correcting and cutting off the position report when one ZC comprises a plurality of adjacent ZCs, so that the train can be transferred and taken over into the ZC smoothly and seamlessly without speed reduction.
