Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a train handover method and system. Background Art

[0002] In rail transit line design, several stations in a line will be divided into a zone controller (ZoneController, ZC) concentration area. The boundary between two ZC concentration areas is called the "handover boundary". Usually, a part of the track section on the left side of the handover boundary point is used as the section in the overlapping area of ​​the left ZC, and a part of the track section on the right side of the handover boundary point is used as the section in the overlapping area of ​​the right ZC. According to the data configuration, the handover ZC can identify the sections within the overlapping area of ​​the takeover ZC, and the takeover ZC can identify the sections within the overlapping area of ​​the handover ZC. Each ZC with the same handover boundary will periodically transmit station information such as the physical sections, switches, station delay status, track section train sequencing, etc. within their respective jurisdictions in the overlapping area. The schematic diagram of train cross-zone handover is shown in the figure. Figure 1 shown.

[0003] The train transfer process diagram is as follows Figure 2 As shown, the train is located within the overlapping area of ​​the handover ZC and is passing through the overlapping area of ​​the handover ZC to the takeover ZC for cross-area handover. In order to improve the efficiency of train handover and takeover, when the maximum safe front position of the train enters the overlapping area of ​​the handover ZC, the train will send the handover train information to the takeover ZC; when the movement authorization (Movement Authorization) MA1 of the train reaches the handover boundary, the handover ZC will issue additional train handover status information, and the train handover process will start at this time; the takeover ZC will calculate MA2 for the train from the handover boundary based on the train information (including train position report), train handover status information and station information sent by the handover ZC, and send the MA2 information to the handover ZC through the train handover status information; after receiving the MA2 information, the handover ZC will splice the MA1 information and MA2 information to form a new MA information and send it to the train, so that the train can smoothly and seamlessly cross the handover boundary without slowing down and enter the jurisdiction of the takeover ZC, realizing the train handover and takeover function of mobile block tracking.

[0004] Based on the mobile block tracking, when the train is transferred across zones, the handing ZC will send the handing train information to the taking-over ZC. If the train position report information sent by the handing ZC does not belong to the jurisdiction of the taken-over ZC, the taking-over ZC cannot recognize the train position report information, resulting in the problem that the train cannot run normally across zones, such as Figure 3As shown in the figure: the section where the train tail is located is SEG05, which does not belong to the overlapping area of ​​the handover ZC (the track sections included in the overlapping area of ​​the handover ZC are SEG01 and SEG02); at this time, if the handover ZC sends a real position report to the takeover ZC, the takeover ZC cannot identify SEG05 (the takeover ZC can identify SEG01 and SEG02), which leads to the takeover ZC believing that the position information sent by the handover ZC is illegal and discards the handover train information, which eventually leads to the interruption of communication between the handover ZC and the takeover ZC. Similarly, when the train passes the handover boundary and leaves the overlapping area boundary of the takeover ZC, the track section where the maximum safe front position of the train is located is SEG06, which cannot be identified by the handover ZC (the handover ZC can only identify SEG03 and SEG04), so the handover ZC believes that the handover train information sent by the takeover ZC is illegal, resulting in the interruption of communication between the handover ZC and the takeover ZC, which directly affects the normal cross-zone handover and takeover of the train.

[0061] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] The train handover method provided by the present invention can realize the function of cross-zone handover and takeover of trains when a ZC under the Communication Based Train Control (CBTC) system contains multiple adjacent ZCs, so that the train can smoothly and seamlessly cross the handover boundary and enter the jurisdiction of the takeover ZC without slowing down. The specific implementation is as follows:

[0063] Figure 4 It is one of the flow charts of the train transfer method provided by the present invention, such as Figure 4 As shown, the method includes:

[0064] Step 100: When it is determined that the train safety envelope meets the first preset condition, first train handover information of the train is sent to the first zone controller ZC;

[0065] Step 200: When it is determined that the train safety envelope meets the second preset condition, second train handover information is sent to the first ZC;

[0066] The train handover information includes at least train movement authorization, train handover status information, train position report and station information. The station information includes at least the physical section, turnout, station delay status and track section train sequencing within the jurisdiction of the second ZC.

[0067] The first ZC is adjacent to the second ZC.

[0068] It should be noted that the execution subject of the above method may be the second ZC.

[0069] Alternatively, see Figure 5 , the handover ZC overlapping area (i.e., the second ZC overlapping area) and the adjacent ZC overlapping area (i.e., the first ZC overlapping area) are divided according to the handover boundary points of each ground ZC control area, and the overlapping area attributes to which the track segment belongs are specified: the handover ZC overlapping area attributes and the adjacent ZC overlapping area attributes.

[0070] It should be noted that the handover ZC and the adjacent ZC are relative, such as Figure 6 As shown, for ZC1, ZC1 is the handover ZC, and ZC2 is its adjacent ZC. The overlapping area of ​​ZC1 is the handover ZC overlapping area, which includes track segments SEG01 and SEG02, and the adjacent ZC overlapping area of ​​ZC1 is the ZC2 overlapping area, which includes track segments SEG03 and SEG04; for ZC2, ZC2 is the handover ZC, and ZC1 is its adjacent ZC. The overlapping area of ​​ZC2 is the handover ZC overlapping area, which includes track segments SEG03 and SEG04, and the adjacent ZC overlapping area of ​​ZC2 is the ZC1 overlapping area, which includes track segments SEG01 and SEG02.

[0071] If the handover ZC (i.e., the second ZC) believes that any part of the train safety envelope is within the jurisdiction of the second ZC overlapping area, then the second ZC shall send the handover train information of the train to all its adjacent first ZCs. The schematic diagram of the train safety envelope is as follows: Figure 7 shown.

[0072] In one embodiment, when it is determined that the train safety envelope satisfies the first preset condition, first train handover information of the train (handover train) is sent to the first zone controller ZC.

[0073] In one embodiment, the first preset condition may specifically include that the minimum safe front position of the train, the maximum safe front position of the train, the maximum safe rear position of the train and the minimum safe rear position of the train in the train safety envelope are all located in the second ZC overlapping area; the second preset condition includes the first judgment condition, the second judgment condition and the third judgment condition.

[0074] When the second ZC determines that the train safety envelope meets the second preset condition, second train handover information is sent to the first ZC.

[0075] The train handover method provided by the present invention can realize the functions of inter-area handover and takeover of trains in a moving block tracking manner.

[0076] Furthermore, in one embodiment, step 200 may specifically include:

[0077] Step 2001: When it is determined that the train safety envelope satisfies the first judgment condition, the train rear position in the train position report is truncated and corrected, and the train maximum safe rear end position and the train minimum safe rear end position in the train position report are truncated to the first ZC overlapping area boundary point or the second ZC overlapping area boundary point, and the train maximum safe rear end position and the train minimum safe rear end position are corrected;

[0078] Step 2002: Determine the handover information of the second train according to the corrected train rear position, the corrected maximum safe rear position of the train, and the corrected minimum safe rear position of the train;

[0079] Step 2003: Send the second train handover information to the first ZC;

[0080] The first judgment condition includes: the maximum safe front position of the train is located in the second ZC overlapping area, the minimum safe rear position of the train is not located in the second ZC overlapping area, and the minimum safe rear position of the train is not located in the first ZC overlapping area;

[0081] The corrected train rear position is located in the track section within the jurisdiction of the second ZC or the track section within the jurisdiction of the first ZC.

[0082] Alternatively, see Figure 5 , if the maximum safe front position of the train is located in the overlapping area of ​​the second ZC, the minimum safe rear position of the train is not located in the overlapping area of ​​the second ZC, and the minimum safe rear position of the train is not located in the overlapping area of ​​the first ZC, that is, when the train has not completely entered the overlapping area of ​​the handover ZC during cross-zone handover (the same is true for some atypical special scenarios, such as when the train enters the handover ZC from an adjacent ZC, the front of the train has passed the handover boundary but the rear of the train has not entered the overlapping area of ​​the adjacent ZC), the train position report in the handover train information needs to truncate and correct the rear position of the train (the corrected rear position of the train is located in the track section within the jurisdiction of the second ZC or the track section within the jurisdiction of the first ZC), truncate the maximum safe rear position of the train and the minimum safe rear position of the train to the boundary point of the first ZC overlapping area or the boundary point of the second ZC overlapping area, and then send the train handover information (i.e., the second train handover information) including the corrected train position report to the adjacent ZC (i.e., the first ZC), such as Figure 8 shown.

[0083] The train handover method provided by the present invention elaborates in detail the algorithm for correcting and truncating the position report information (train tail position, train maximum safe rear end position and train minimum safe rear end position) in the handover train information sent by the ground ZC during the inter-zone handover and takeover of the train in the CBTC system, thereby filling the gap in the implementation details of the position report truncation processing technology under the inter-zone handover and takeover functions of the train in the CBTC system, and realizing the functions of inter-zone handover and takeover of the train.

[0084] Furthermore, in one embodiment, step 200 may further specifically include:

[0085] Step 2004: when it is determined that the train safety envelope satisfies the second judgment condition, the actual position of the train in the train position report is corrected according to the minimum safe front position of the train, the maximum safe front position of the train, the maximum safe rear position of the train and the minimum safe rear position of the train in the train safety envelope;

[0086] Step 2005: Determine the handover information of the second train according to the corrected actual position of the train;

[0087] Step 2006: Send the second train handover information to the first ZC;

[0088] The second judgment condition includes: when the maximum safe front end position of the train is located in the second ZC overlapping area, the minimum safe rear end position of the train is located in the second ZC overlapping area or the first ZC overlapping area.

[0089] Optionally, continue to see Figure 5 If the maximum safe front 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 minimum safe rear end position of the train is located in the first ZC overlapping area, the actual position of the train in the train position report shall be corrected according to the minimum safe front position, maximum safe front position, minimum safe rear end position and minimum safe rear end position of the train in the train safety envelope, and the train position report in the second handover train information shall be sent to the adjacent ZC (first ZC) according to the actual position of the train.

[0090] like Fig. 9 As shown, in one embodiment, when the train safety envelope is completely located within the overlapping area of ​​ZC1, the train position report (the maximum safe front position of the train, the maximum safe rear position of the train and the minimum safe rear position of the train) sent by ZC1 to ZC2 is the actual position of the train, and at this time ZC2 will not send the second handover train information to ZC1; when the train safety envelope is completely located within the overlapping area of ​​ZC2, the train position report (the position information of the four ends) sent by ZC2 to ZC1 is the actual position of the train, and at this time ZC1 will not send the handover train information to ZC2.

[0091] like Fig.10 As shown, in one embodiment, when the train is located on the handover boundary, the above-mentioned second judgment condition is met. At this time, ZC1 and ZC2 will send second handover train information to each other, and the train position report in the sent second handover train information is the location point of the actual position of the train.

[0092] The train handover method provided by the present invention elaborates in detail the algorithm for correcting and truncating the position report information (actual position of the train) in the handover train information sent by the ground ZC during the inter-zone handover and takeover process of the train in the CBTC system, thereby filling the gap in the implementation details of the position report truncation processing technology under the inter-zone handover and takeover functions of the train in the CBTC system, and realizing the functions of inter-zone handover and takeover of the train.

[0093] Furthermore, in one embodiment, step 200 may further specifically include:

[0094] Step 2007: When it is determined that the train safety envelope satisfies the third judgment condition, the train head position in the train position report is truncated and corrected, and the train maximum safety front position and the train minimum safety front position in the train position report are truncated to the first ZC overlapping area boundary point or the second ZC overlapping area boundary point, and the train maximum safety front position and the train minimum safety front position are corrected;

[0095] Step 2008: Determine the second train handover information according to the corrected train head position, the corrected train maximum safe front position and the corrected train minimum safe front position;

[0096] Step 2009: Send the second train handover information to the first ZC;

[0097] The third judgment condition includes: a first sub-judgment condition and a second sub-judgment condition;

[0098] The first sub-determination condition includes: the maximum safe front position of the train is not located in the second ZC overlap area and the minimum safe rear position of the train is located in the second ZC overlap area;

[0099] The second sub-judgment condition includes: the maximum safe front position of the train is not located in the second ZC overlapping area, the minimum safe rear position of the train is not located in the second ZC overlapping area, and the minimum safe rear position of the train is located in the first ZC overlapping area;

[0100] The corrected train head position is located in the track section within the jurisdiction of the second ZC or the track section within the jurisdiction of the first ZC.

[0101] Optionally, continue to see Figure 5 If the maximum safe front position of the train is not located in the second ZC overlapping area and the minimum safe rear position of the train is located in the second ZC overlapping area, that is, the scenario where the train normally drives out of the overlapping area, the train position report in the second handover train information needs to truncate and correct the train head position (the corrected train head position is located in the track section within the jurisdiction of the second ZC or the track section within the jurisdiction of the first ZC), and truncate the maximum safe front position of the train and the minimum safe front position of the train to the boundary point of the first ZC overlapping area or the boundary of the second ZC overlapping area, and then send the second train handover information including the corrected train position report to the adjacent ZC (that is, the first ZC), as follows Fig.11 shown.

[0102] If the maximum safe front position of the train is not located in the second ZC overlapping area, the minimum safe rear position of the train is not located in the second ZC overlapping area, and the minimum safe rear position of the train is located in the first ZC overlapping area, this scenario is also an atypical special scenario for the train to normally exit the overlapping area, that is, when the overlapping area is short and the train length is long, this atypical scenario will occur. 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 the track section within the jurisdiction of the second ZC or the track section within the jurisdiction of the first ZC), truncate the maximum safe front position and the minimum safe front position of the train to the boundary point of the first ZC overlapping area or the boundary of the second ZC overlapping area, and then send the second train handover information including the corrected train position report to the adjacent ZC (that is, the first ZC), such as Fig.12 shown.

[0103] The train handover method provided by the present invention elaborates in detail the algorithm for correcting and truncating the position report information (train head position, train maximum safe front position and train minimum safe front position) in the handover train information sent by the ground ZC during the inter-zone handover and takeover process of the train in the CBTC system, thereby filling the gap in the implementation details of the position report truncation processing technology under the inter-zone handover and takeover functions of the train in the CBTC system, and realizing the functions of inter-zone handover and takeover of the train.

[0104] Furthermore, in one embodiment, the method may further specifically include:

[0105] When it is determined that the train safety envelope satisfies the third preset condition, the first train handover information is not sent to the first ZC;

[0106] Among them, the third preset condition includes: the maximum safe front position of the train is not located in the second ZC overlapping area, the minimum safe rear position of the train is not located in the second ZC overlapping area, and the minimum safe rear position of the train is not located in the first ZC overlapping area.

[0107] Optionally, continue to see Figure 5 If the maximum safe front position of the train is not located in the overlapping area of ​​the second ZC, the minimum safe rear position of the train is not located in the overlapping area of ​​the second ZC, and the minimum safe rear position of the train is not located in the overlapping area of ​​the first ZC, it is considered that the train position is abnormal or has completely driven out of the overlapping area of ​​the takeover ZC (i.e., the first ZC). At this time, the second ZC should not send the first train handover information to the first ZC.

[0108] The taking over ZC (i.e. the first ZC) determines whether to start or end the handover and takeover process based on the handover train information sent by the handover ZC and the train position report information, and completes the train cross-zone handover and takeover functions under mobile block tracking.

[0109] In one embodiment, for a scenario where a second ZC includes multiple adjacent first ZCs, the position report truncation processing algorithm is also applicable, such as Fig.13 As shown: ZC1 (the second ZC) includes two adjacent ZCs: ZC2 and ZC3 (i.e., the first ZC), wherein the adjacent ZC overlapping area of ​​ZC2 overlaps with the adjacent ZC overlapping area of ​​ZC3. When the train crosses the handover boundary from ZC2 into ZC1, ZC1 determines that the maximum safe front position of the train is located in the ZC1 overlapping area, and the minimum safe rear position of the train is not in the ZC1 overlapping area. At this time, the rear position of the train is located in the ZC2 overlapping area, but not in the ZC3 overlapping area; the handover train information sent by ZC1 to ZC2 and the handover train information sent by ZC2 to ZC1 are all sent according to the actual position of the train; and in the handover train information sent by ZC1 to ZC3, the rear position of the train in the train position report is truncated to the boundary point of the ZC1 overlapping area or the boundary of the ZC3 overlapping area. At this time, ZC3 receives the handover train information sent by ZC1 and the communication between ZC3 and ZC1 will not be interrupted due to the inability to recognize the train position report.

[0110] The train handover method provided by the present invention elaborates in detail the algorithm for correcting and truncating the position report information in the handover train information sent by the ground ZC during the inter-zone handover and takeover process of the train in the CBTC system, thereby filling the gap in the implementation details of the position report truncation processing technology under the inter-zone handover and takeover functions of the train in the CBTC system, and is scalable. For example, when a ZC contains multiple adjacent ZCs, the method is also applicable to perform position report correction and truncation processing, so that the train does not slow down and smoothly and seamlessly crosses the handover boundary to enter the takeover ZC.

[0111] The train handover system provided by the present invention is described below. The train handover system described below and the train handover method described above can be referenced to each other.

[0113] A first sending module 1410 and a second sending module 1411;

[0114] The first sending module 1410 is used to send first train handover information of the train to the first zone controller ZC when it is determined that the train safety envelope meets the first preset condition;

[0115] The second sending module 1411 is used to send second train handover information to the first ZC when it is determined that the train safety envelope meets the second preset condition;

[0116] The train handover information includes at least the train movement authorization, the train handover status information, the train position report and the station information, and the station information includes at least the physical section, turnout, station delay status and track section train sequence within the jurisdiction of the second ZC;
