[0003] Locomotive tracking technology is widely used, and existing methods mainly include satellite positioning tracking and track circuit tracking. Satellite positioning tracking, represented by GPS technology, has been applied to the rail transit field; however, it is affected by many objective factors, including positioning accuracy, building structures, and weather conditions. Therefore, the stability of this method is difficult to meet the high requirements of locomotive and rolling stock tracking in the rail transit sector. Track circuit tracking methods typically determine the locomotive's position by checking the occupancy and clearance of track circuits. However, abnormal occupancy of track circuits can occur, so relying solely on track circuit occupancy and clearance for locomotive tracking lacks sufficient reliability and accuracy.

[0022] Combined with appendix Figures 1-7 As shown, this embodiment provides a locomotive number tracking method, including: Step S11, processing the shunting route for the locomotive number and obtaining the station signal equipment representation information; Step S12, obtaining the running direction of the locomotive number based on the station signal equipment representation information; Step S13, searching for the locomotive number and shunting route based on the station signal equipment logic diagram and the running direction of the locomotive number to obtain an auxiliary tracking data set including the locomotive number, signal, and route locking section; Step S14, obtaining track section representation information when the state of the track section within the shunting route changes; Step S15, matching the track section representation information and the auxiliary tracking data set to search for the starting signal equipment and target signal equipment of the locomotive number's movement, and tracking the locomotive number.
[0023] Specifically, in step S11, when processing the shunting route for the locomotive number, the locomotive number of the corresponding locomotive needs to be added. The station signal equipment representation information includes the station number of the station where the signal equipment is located, the type of signal equipment, the serial number of the signal equipment, and the status information of the signal equipment; and the signal equipment includes signals and track sections. The signals include entry signals, exit signals, shunting signals, receiving route signals, departure route signals, advance warning signals, and passing signals, etc. The track sections include tracks, non-turnout sections, and turnout sections, etc., but the present invention is not limited thereto.
[0024] Specifically, step S12 includes: step S121, determining whether the signal device is a shunting signal based on its type; step S122, if the signal device is a shunting signal, determining whether the shunting signal is open for permission based on the status information of the signal device; step S123, if the shunting signal is open for permission, obtaining the running direction of the locomotive number based on the protection direction of the shunting signal.
[0025] In this embodiment, in step S121, the type of each signal device in the station signal equipment information is determined one by one to determine whether it is a shunting signal. If the signal device is not a shunting signal, the operation ends; if the signal device is a shunting signal, step S122 is executed. In step S122, if the status information of the signal device is a blue light, indicating that the shunting signal is not open for permission, the operation ends; if the status information of the signal device is a pale white light, indicating that the shunting signal is open for permission, step S123 is executed. In step S123, the locomotive number's running direction includes both up and down traffic.
[0026] Specifically, step S13 includes: Step S131, according to the station signal equipment logic diagram, searching for signal equipment adjacent to the shunting signal in the station yard in the opposite direction of the locomotive number's running direction and recording it as the first reverse adjacent signal equipment; Step S132, if the first reverse adjacent signal equipment is a track section that is occupied and has a locomotive number, recording the locomotive number; Step S133, starting from the shunting signal, according to the station signal equipment logic diagram, searching for signal equipment adjacent to the shunting signal in the station yard in the running direction of the locomotive number and recording it as the first same-direction adjacent signal equipment; Step S134, if the first same-direction adjacent signal equipment is a locked track section, recording the locked section; Step S135, continuing to search for the next first same-direction adjacent signal equipment in the station yard in the running direction of the locomotive number; Step S136, if the next first same-direction adjacent signal equipment is an unlocked track section, stopping the search and generating the auxiliary tracking data set.
[0027] In this embodiment, as Figure 2 As shown, step S132 includes: Step S1321, determining whether the first reverse adjacent signal device is a track section; if not, proceeding to step S131; if yes, proceeding to step S1322. Step S1322, determining whether the current state of the first reverse adjacent signal device is occupied; if not, proceeding to step S133; if yes, proceeding to step S1323. Step S1323, determining whether the current state of the first reverse adjacent signal device includes a locomotive number; if not, proceeding to step S131; if yes, recording the locomotive number. It can be seen from the above that the condition for ending the search for signal devices adjacent to the shunting signal in the station yard according to the opposite direction of the locomotive's running direction is: the signal device found according to the opposite direction of the locomotive's running direction is a track section that is occupied and has a locomotive number; or the signal device found according to the opposite direction of the locomotive's running direction is not occupied.
[0028] In this embodiment, step S134 includes: Step S1341, determining whether the first adjacent signal device in the same direction is a track section; if not, proceeding to step S133; if yes, proceeding to step S1342. Step S1342, determining whether the first adjacent signal device in the opposite direction is a locked track section; if not, determining the shunting operation route, stopping the search and generating the auxiliary tracking data set; if yes, proceeding to step S135.
[0029] Specifically, in step S14, the track section representation information includes the station number of the station where the track section is located, the type of track section, the sequence number of the track section, and the status information of the track section (e.g., status is occupied, cleared, or poorly separated, and whether there is a locomotive number).
[0030] Specifically, step S15 includes: step S151, when the current state of the track section within the shunting route is occupied and there is no locomotive number, the corresponding track section is used as the target signal device for the locomotive number to move; step S152, the track section used as the target signal device for the locomotive number to move is matched with the auxiliary tracking data set to obtain the running direction of the locomotive number within the shunting route; step S153, according to the station signal equipment logic diagram, the signal device adjacent to the shunting signal in the station yard is searched in the opposite direction of the locomotive number's running direction and recorded as the second reverse adjacent device; step S154, when the second reverse adjacent device is a track section in the station yard that is occupied and has a locomotive number, the second reverse adjacent device is used as the starting signal device for the locomotive number to move; and step S155, the locomotive number is moved from the starting signal device to the target signal device.
[0031] Specifically, the operation of matching track sections with auxiliary tracking data includes one or any combination of the following: comparing the target signaling device with the route locking section in the auxiliary tracking data set, comparing the locomotive number of the starting signaling device with the locomotive number in the auxiliary tracking data set, and comparing the direction of movement of the locomotive number with the protection direction of the shunting signal in the auxiliary tracking data set.
[0032] In this embodiment, as Figure 3 As shown, in step S151, the operation ends when the current state of the track section within the shunting route is occupied and a locomotive number is present. In step S152, it is determined whether the track section serving as the target signal device for the locomotive number's movement matches (i.e., whether they are consistent) with the route locking section in the auxiliary tracking data set. If they match, the locomotive's running direction determined in step S123 is taken as the locomotive's running direction within the shunting route. If they do not match, the up direction or down direction is taken sequentially as the locomotive's running direction within the shunting route until the starting signal device for the locomotive's movement is found or both directions have been traversed.
[0033] In this embodiment, step S154 includes: Step S1541: Determine whether the second reverse adjacent signal device is a signal device of this station yard; if not, determine whether the starting signal device for the locomotive number has been determined; if yes, proceed to step S1542. Step S1542: Determine whether the second reverse adjacent signal device is a track section; if not, proceed to step S153; if yes, proceed to step S1543. Step S1543: Determine whether the current state of the second reverse adjacent signal device is occupied; if not, determine whether the starting signal device for the locomotive has been determined; if yes, proceed to step S1544. Step S1544: Determine whether the current state of the second reverse adjacent signal device includes the locomotive number; if not, proceed to step S153; if yes, use the second reverse adjacent device containing the locomotive number as the starting signal device for the locomotive number to move. Before executing step S155, the method further includes: determining whether the starting signal device of the locomotive has been determined; if it has been determined, then executing step S155; if it has not been determined, then ending the operation. Furthermore, before executing step S155, the method may also include: matching the locomotive number of the starting signal device with the locomotive number in the auxiliary tracking data set, or comparing the direction of movement of the locomotive number with the protection direction of the shunting signal in the auxiliary tracking data set, but the present invention is not limited thereto.
[0034] In some embodiments, step S15 further includes: step S156, when the current state of the track section within the shunting route is cleared, obtaining the previous state of the track section; step S157, when the previous state of the track section was occupied and there was a locomotive number, using the track section as the starting signal device for the locomotive number to move; step S158, matching the track section used as the starting signal device for the locomotive number to move with the auxiliary tracking data set to obtain the running direction of the locomotive number within the shunting route; step S159, according to the station signal equipment logic diagram, searching for signal devices adjacent to the shunting signal in the station yard in the opposite direction of the locomotive's running direction and recording them as the third reverse adjacent device; step S160, when the third reverse adjacent device is a track section in the station yard that is occupied and has no locomotive number, using the third reverse adjacent device as the target signal device for the locomotive number to move; step S161, moving the locomotive number from the starting signal device to the target signal device.
[0035] In this embodiment, step S157 includes: Step S1571, determining whether the previous state of the track section was occupied; if not, the operation ends; if yes, step S1572 is executed. Step S1572, determining whether the previous state of the track section contained a locomotive number; if not, the operation ends; if yes, the track section containing the locomotive number is used as the starting signal device for the locomotive's movement.
[0036] In step S158, it is determined whether the locomotive number of the starting signal device matches (i.e., whether they are consistent) with the locomotive number in the auxiliary tracking data set. If they match, the running direction of the locomotive determined in step S123 is taken as the running direction of the locomotive number in the shunting route. If they do not match, the up direction or down direction is taken as the running direction of the locomotive number in the shunting route, until the target signal device for the locomotive number is found or both directions have been traversed.
[0037] Step S160 includes: Step S1601: Determine whether the third reverse adjacent signal device is a signal device of this station yard; if not, determine whether the target signal device for the locomotive number has been determined; if yes, proceed to step S1602. Step S1602: Determine whether the third reverse adjacent signal device is a track section; if not, proceed to step S159; if yes, proceed to step S1603. Step S1603: Determine whether the current state of the third reverse adjacent signal device is occupied; if not, determine whether the target signal device for the locomotive number has been determined; if yes, proceed to step S1604. Step S1604: Determine whether the current state of the third reverse adjacent signal device includes the locomotive number; if it does, determine whether the target signal device for the locomotive number has been determined; if not, use the third reverse adjacent device as the target signal device for moving the locomotive number. Before executing step S161, the method further includes: determining whether the target signaling device for the locomotive number has been determined; if it has been determined, then executing step S161; if it has not been determined, then ending the operation. Furthermore, before executing step S161, the method may also include: matching the starting signaling device with the route locking section in the auxiliary tracking data set, or comparing the direction of movement of the locomotive number with the protection direction of the shunting signal in the auxiliary tracking data set, but the present invention is not limited thereto.
[0038] In some embodiments, step S15 further includes: step S162, when the current state of the track section in the shunting route is poorly oriented, determining whether the track section matches the auxiliary tracking data set; if they match, the current state of the track section is considered occupied.
[0039] like Figure 4 and Figure 5The diagram illustrates the processing of locomotive number changes when entering a track section. Locomotive number 0088 is located in the switchless section IIIAG, with shunting routes D1-D5 in progress ahead. Shunting signal D1 is open and permitted. Based on the protection direction of shunting signal D1, the running direction of locomotive number 0088 is determined to be downhill. Combining the locomotive number information and the locked switch sections 1-3DG within the route, an auxiliary tracking data set is generated. When switch sections 1-3DG become occupied (red light), the occupancy status information of switch sections 1-3DG can be obtained. First, it is checked whether the status of switch sections 1-3DG contains locomotive number information. If not, switch sections 1-3DG are used as the target signal device for locomotive number 0088's movement. Then, the status of switch sections 1-3DG is matched with the auxiliary tracking data set to determine the running direction as downhill. Next, the adjacent track sections are searched according to the uphill direction (opposite to the running direction), and their status is checked to see if they are occupied and contain locomotive number information. If the conditions are met when the non-switching section IIIAG is found, and the current status of IIIAG is occupied and there is locomotive number adjustment information 0088, then the non-switching section IIIAG is used as the starting signal device for the movement of locomotive number adjustment 0088. Then, locomotive number adjustment 0088 is moved from the starting point non-switching section IIIAG to the ending point turnout section 1-3DG to achieve locomotive number tracking.
[0040] like Figure 6 and Figure 7 The diagram illustrates the process of canceling the occupation of a locomotive's track section. Shunting routes D1-D5 have been processed. After track I was occupied, locomotive number 0088 moved from turnout section 1-3DG to track I. To cancel track I, the clearance status of track I can be obtained. First, it is checked whether the original status of the track was occupied and whether a locomotive number was present. If so, track I is used as the starting signal for locomotive number 0088's movement. Then, the track I information is matched with the auxiliary tracking data set, indicating the running direction is down. Next, the adjacent track sections are searched in the up direction (opposite to the running direction), checking whether they are occupied and lack locomotive number information. When turnout section 1-3DG is found, it meets the conditions; the current status of turnout section 1-3DG is occupied and lacks locomotive number information, making it the target signal for locomotive movement. When continuing to search for the non-switching section IIIAG, since IIIAG is not in an occupied state and does not meet the conditions, the search ends. Finally, the turnout section 1-3DG is used as the target signal device for locomotive movement, and the locomotive number is adjusted to 0088 and moved from the starting track I to the ending turnout section 1-3DG to achieve locomotive number tracking.
[0041] Based on the same inventive concept, this embodiment also provides a locomotive number tracking system for performing the locomotive number tracking method described above.
[0042] In summary, the locomotive number tracking method and system provided in this embodiment, after processing the shunting route of the locomotive, obtains the locomotive's running direction based on the information displayed by the station signal equipment; based on the station signal equipment logic diagram and the locomotive's running direction, an auxiliary tracking data set can be obtained, which includes the locomotive number, signal, and route locking section; when the state of the track section within the shunting route changes, track section representation information can be obtained; and the track section representation information and the auxiliary tracking data set are matched to search for the starting and target signal equipment for the locomotive's movement, thereby achieving locomotive number tracking. This embodiment, based on track circuit tracking, combines preconditions such as signals and route locking sections to assist locomotive number tracking, while also adapting to abnormal situations such as poor track circuit shunting, effectively and correctly achieving locomotive number tracking, improving the accuracy and reliability of locomotive number tracking and reporting.
