Description

Locomotive number tracking method and system Technical Field

[0001] The present invention relates to the field of rail transportation technology, and in particular to a locomotive number tracking method and system based on station signal status. Background Art

[0002] Shunting is a fundamental part of railway operations and a crucial component of railway transport production. For marshaling yards, where a large number of train formations and dismantlings occur, shunting is a crucial production activity, and accurate tracking of locomotive numbers is essential for efficient and accurate shunting.

[0003] Locomotive tracking technology is widely used. Existing methods primarily include satellite positioning and track circuit tracking. Satellite positioning, represented by GPS, has been applied to rail transit, but is subject to numerous factors, including positioning accuracy, buildings, and weather. Therefore, this method's stability struggles to meet the high demands of locomotive tracking in rail transit. Track circuit tracking typically determines locomotive location based on track circuit occupancy and clearance. However, track circuits can be subject to abnormal occupancy, so relying solely on track circuit occupancy and clearance to track locomotive tracking is inherently unreliable and inaccurate.

[0029] In conjunction with Figures 1 to 7, this embodiment provides a locomotive number tracking method, including: step S11, processing the shunting route of the locomotive number and obtaining the station yard signal equipment indication information; step S12, obtaining the running direction of the locomotive number according to the station yard signal equipment indication information; step S13, searching the locomotive number and shunting route according to the station yard signal equipment logic diagram and the running direction of the locomotive number to obtain an auxiliary tracking data set including the locomotive number, signal machine and route locking section; step S14, when the state of the track section in the shunting route changes, obtaining the track section indication information; step S15, matching the track section indication information with the auxiliary tracking data set to search for the starting signal equipment and target signal equipment of the locomotive number movement to track the locomotive number.

[0030] 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 signal equipment, 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 signal machines and track sections. The signal machines include entry signals, exit signals, shunting signals, receiving route signals, departure route signals, advance signals, passing signals, etc. The track sections include track sections, non-switch sections, and switch sections, etc., but the present invention is not limited to this.

[0031] Specifically, the step S12 includes: step S121, judging whether the signal device is a shunting signal according to the type of the signal device; step S122, when the signal device is a shunting signal, judging whether the shunting signal is open to allow the signal according to the status information of the signal device; step S123, when the shunting signal is open to allow the signal, obtaining the running direction of the locomotive number according to the protection direction of the shunting signal.

[0032] In this embodiment, in step S121, the signal device is determined one by one based on the type of signal device in the station signal device indication information to determine whether it is a shunting signal. If the signal device is not a shunting signal, the operation is terminated. 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 does not have a permission signal, the operation is terminated. If the status information of the signal device is a moon-white light, indicating that the shunting signal has a permission signal, step S123 is executed. In step S123, the reverse direction of the locomotive number includes both up and down travel.

[0033] Specifically, the step S13 includes: step S131, according to the station signal equipment logic diagram, search for the signal equipment adjacent to the shunting signal in the station in the opposite direction of the running direction of the locomotive number and record it as the first reverse adjacent signal equipment; step S132, when the first reverse adjacent signal equipment is a track section that is in an occupied state and has a locomotive number, record the locomotive number; step S133, starting from the shunting signal, according to the station signal equipment logic diagram, search for the signal equipment adjacent to the shunting signal in the station in the running direction of the locomotive number and record it as the first same-direction adjacent signal equipment; step S134, when the first same-direction adjacent signal equipment is a locked track section, record the locked section; step S135, continue to search for the next first same-direction adjacent signal equipment in the station according to the running direction of the locomotive number; step S136, when the next first same-direction adjacent signal equipment is an unlocked track section, stop searching and generate the auxiliary tracking data set.

[0034] In this embodiment, as shown in FIG2 , step S132 includes: step S1321, determining whether the first reverse adjacent signal device is a track section; if not, executing step S131; if so, executing step S1322. Step S1322, determining whether the current state of the first reverse adjacent signal device is occupied; if not, executing step S133; if so, executing step S1323. Step S1323, determining whether the current state of the first reverse adjacent signal device includes a locomotive number; if not, executing step S131; if included, recording the locomotive number. As can be seen from the above, the conditions for ending the search for signal devices adjacent to the shunting signal in the station yard in the opposite direction of the locomotive's running direction are: the signal device found in the opposite direction of the locomotive's running direction is a track section in an occupied state and has a locomotive number; or the signal device found in the opposite direction of the locomotive's running direction is not occupied.

[0035] 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, executing step S133; if so, executing 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 so, executing step S135.

[0036] 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 the track section, the serial number of the track section and the status information of the track section (such as the status is occupied, cleared or poorly diverted, etc. and whether there is a locomotive number).

[0037] Specifically, the step S15 includes: step S151, when the current status of the track section in the shunting route is occupied and there is no locomotive number, the corresponding track section is used as the target signal device for the movement of the locomotive number; step S152, the track section as the target signal device for the movement of the locomotive number is matched with the auxiliary tracking data set to obtain the running direction of the locomotive number in the shunting route; step S153, according to the station signal equipment logic diagram, the signal equipment adjacent to the shunting signal in the station yard is searched in the opposite direction of the running direction of the locomotive number and recorded as the second reverse adjacent equipment; step S154, when the second reverse adjacent equipment is the track section of the station yard that is in an occupied state and has a locomotive number, the second reverse adjacent equipment is used as the starting signal equipment for the movement of the locomotive number; and step S155, the locomotive number is moved from the starting signal equipment to the target signal equipment.

[0038] Specifically, the operation of matching the track section with the auxiliary tracking data includes: comparing the target signal device with the approach locking section in the auxiliary tracking data set, comparing the locomotive number of the starting signal 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, or any combination thereof.

[0039] In this embodiment, as shown in Figure 3, in step S151, if the current status of the track section within the shunting route is occupied and a locomotive number is present, the operation is terminated. In step S152, a determination is made as to whether the track section serving as the target signaling device for the locomotive number's movement matches (i.e., is consistent with) the route-locked section in the auxiliary tracking data set. If so, the locomotive's running direction determined in step S123 is used as the locomotive's running direction within the shunting route. If not, the upward or downward direction is used sequentially as the locomotive's running direction within the shunting route until the locomotive's starting signaling device is found or both directions have been traversed.

[0040] In this embodiment, step S154 includes: step S1541, determining whether the second reverse-adjacent signal device is a signal device of the current station; if not, determining whether the starting signal device of the locomotive number has been determined; if so, executing step S1542. Step S1542, determining whether the second reverse-adjacent signal device is a track section; if not, executing step S153; if so, executing step S1543. Step S1543, determining whether the current state of the second reverse-adjacent signal device is occupied; if not, determining whether the starting signal device of the locomotive has been determined; if so, executing step S1544.

Before executing step S155, the method further includes: determining whether the locomotive's starting signal device has been determined; if so, executing step S155; if not, terminating the operation. Furthermore, before executing step S155, the method further includes: matching the locomotive number of the starting signal device with the locomotive number in the auxiliary tracking data set, or comparing the locomotive number's moving direction with the protection direction of the shunting signal in the auxiliary tracking data set, but the present invention is not limited thereto.

[0041] In some embodiments, the step S15 also includes: step S156, when the current state of the track section in the shunting route is clear, obtaining the previous state of the track section; step S157, when the previous state of the track section is occupied and there is a locomotive number, using the track section as the starting signal device for the movement of the locomotive number; step S158, matching the track section as the starting signal device for the movement of the locomotive number with the auxiliary tracking data set to obtain the running direction of the locomotive number in the shunting route; step S159, according to the station signal equipment logic diagram, searching for the signal equipment adjacent to the shunting signal in the station in the opposite direction of the running direction of the locomotive and recording it as the third reverse adjacent equipment; step S160, when the third reverse adjacent equipment is a track section in the station that is in an occupied state and has no locomotive number, using the third reverse adjacent equipment as the target signal equipment for the movement of the locomotive number; step S161, moving the locomotive number from the starting signal device to the target signal device.

[0042] In this embodiment, step S157 includes: step S1571, determining whether the previous status of the track segment was occupied; if not, terminating the operation; if so, executing step S1572. Step S1572, determining whether the previous status of the track segment included a locomotive number; if not, terminating the operation; if so, using the track segment containing the locomotive number as the starting signal device for the locomotive's movement.

[0043] In step S158, it is determined whether the locomotive number of the starting signal device matches the locomotive number in the auxiliary tracking data set (i.e., whether they are consistent). If they match, the running direction of the locomotive determined in step S123 is used as the running direction of the locomotive number in the shunting route; if they do not match, the upward direction or the downward direction is used as the running direction of the locomotive number in the shunting route in sequence until the target signal device for the locomotive number to move is found or both directions are traversed.

[0044] Said step S160 includes: step S1601, determining whether the third reverse-adjacent signal device is a signal device of the current station; if not, determining whether the target signal device of the locomotive number has been determined; if so, executing step S1602. Step S1602, determining whether the third reverse-adjacent signal device is a track section; if not, executing step S159; if so, executing step S1603. Step S1603, determining whether the current state of the third reverse-adjacent signal device is occupied; if not, determining whether the target signal device of the locomotive number has been determined; if so, executing step S1604. Step S1604, determining whether the current state of the third reverse-adjacent signal device includes a locomotive number; if so, determining whether the target signal device of the locomotive number has been determined; if not, using the third reverse-adjacent signal device as the target signal device for the locomotive number to be moved. Before executing step S161, the process further includes: determining whether the target signal device for the locomotive has been determined; if so, executing step S161; if not, terminating the operation. Furthermore, before executing step S161, the process further includes: matching the starting signal device with the route locking section in the auxiliary tracking data set, or comparing the locomotive's moving direction with the protection direction of the shunting signal in the auxiliary tracking data set, but the present invention is not limited thereto.

[0045] In some embodiments, the step S15 further includes: step S162, when the current state of the track section within the shunting route is poor branching, determining whether the track section matches the auxiliary tracking data set; if so, the current state of the track section is considered occupied.

[0046] Figures 4 and 5 illustrate the process of changing the track section a locomotive enters. Locomotive 0088 is located in the unconnected section IIIAG. Shunting route D1-D5 is being processed ahead, and shunting signal D1 is open. Based on the protection direction of shunting signal D1, it is determined that locomotive 0088 is traveling in the downward direction. Combined with the locomotive information and the locked switch sections 1-3DG within the route, an auxiliary tracking data set is generated. When switch section 1-3DG changes to an occupied red light band, information indicating its occupied status is available. First, the indicator for switch section 1-3DG is checked to see if it contains the locomotive number. If not, switch section 1-3DG is designated as the target signal for locomotive 0088's movement. The information representing the switch section 1-3DG is then matched with the auxiliary tracking data set. The system then searches for adjacent track sections in the upward direction (opposite to the direction of travel) and checks whether the status is occupied and whether the locomotive number information is present. If the unswitch section IIIAG is found and meets the conditions, and IIIAG's current status is occupied and the locomotive number is 0088, the unswitch section IIIAG is used as the starting signal for the locomotive number 0088 to move. The locomotive number 0088 is then moved from the starting unswitch section IIIAG to the ending switch section 1-3DG, achieving locomotive number tracking.

[0047] Figures 6 and 7 illustrate the process of unoccupying the track section where the locomotive is located. After shunting route D1-D5 has been processed and track I is occupied, locomotive number 0088 moves from switch section 1-3DG to track I. To unoccupy track I, information indicating track I's clearing status is obtained. First, the track is checked to see if it was previously occupied and had a locomotive number. If so, track I is used as the starting signal for locomotive number 0088's movement. This information is then matched with the auxiliary tracking data set, confirming that the travel direction is downward. Next, a search is initiated in the upward direction (opposite to the travel direction) for adjacent track sections, checking whether they are occupied and have no locomotive number information. Finding switch section 1-3DG meets the requirements: it is currently occupied and has no locomotive number information, making it the target signal for the locomotive's movement. When continuing to find the unswitch section IIIAG, since IIIAG is not in occupied state and does not meet the conditions, the search ends, and finally the switch section 1-3DG is used as the target signal equipment for locomotive movement, and the locomotive number is adjusted to 0088 and moved from the starting track I to the ending switch section 1-3DG to realize locomotive number tracking.

[0048] Based on the same inventive concept, this embodiment also provides a locomotive number tracking system for executing the locomotive number tracking method described above.

[0049] In summary, the present embodiment provides a locomotive number tracking method and system. After the locomotive's shunting route is processed, the locomotive's running direction is obtained according to the information indicated by the station signal equipment; an auxiliary tracking data set can be obtained according to the station signal equipment logic diagram and the running direction of the locomotive number, and the auxiliary tracking data set includes the locomotive number, signal machine and route locking section; when the state of the track section in the shunting route changes, the track section indication information can be obtained; and the track section indication information and the auxiliary tracking data set are matched to search for the starting signal equipment and target signal equipment of the locomotive number movement, thereby realizing the tracking of the locomotive number. Based on the track circuit tracking, the present embodiment combines the preconditions such as signal machines and route locking sections to assist the locomotive number tracking, and at the same time adapts to the abnormal situation of poor track circuit branching, which can effectively and correctly realize the locomotive number tracking, and improve the accuracy and reliability of locomotive number tracking and reporting.
