[0002] In urban rail transit, users usually monitor the running process of a train on a track section by using a station yard diagram on an ATS (Automatic Train Supervision) interface.

[0003] Currently, according to the mapping relationship between the section information occupied by a current train and the train window pre-set on the station yard diagram, the position of the train window to be displayed is determined, and the train window at the position is then assigned relevant information of the current train, so that the moving position of the current train can be tracked according to the displayed position of the train window.

[0004] However, since there is a certain distance between the train windows pre-set on the station yard diagram, the tracking of the moving position of the train by using the prior art will produce a jumping moving effect, resulting in a decrease in the accuracy of tracking the moving position of the train.

[0056] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0057] Therefore, the detailed description of the embodiments of the present application provided in the drawings below is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0058] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0059] Before the embodiments of the present application are explained in detail, the application scenario of the present application is first introduced. The application scenario can be specifically a scenario of display of a train state based on an ATS system, wherein the train state can include information such as a moving position and attribute parameters, and a worker can track a moving track of a train in a real environment in real time according to the moving position of the train displayed on an interface, and can understand information of the train according to parameters such as a train set number, a service number and a destination number included in the attribute parameters displayed on the interface. Figure 1 A scenario diagram of an ATS system provided by an embodiment of the present application is shown in FIG. 1. Figure 1As shown, the ATS system includes a display end 101, a service end 102, and a train end 103. The service end 102 is in communication connection with the display end 101 and the train end 103. It can be understood that the city rail transit monitoring interface displayed on the display end 101 displays state information of tracks, axles, signal machines, etc. The tracks are displayed in the form of sections on the city rail transit monitoring interface. The track section displayed on the city rail transit monitoring interface is referred to as a virtual track, and the track section in reality is referred to as a real track. The real track and the virtual track of the same track have a corresponding relationship.

[0060] The train data sensor related to the train end 103 is in communication connection with the service end 102. Therefore, when the train corresponding to the train end 103 sends movement on the real track, the train data sensor can send the related data of the train to the service end 102 in real time. The service end 102 can determine the real track identifier where the train is currently located and the position proportion on the real track according to the received related data of the train, and store the train identifier, the real track identifier where the train is currently located, and the position proportion on the real track in the database in association. The train identifier can be composed of information such as a train set number. The real track identifier and the position proportion on the real track corresponding to the train identifier in the database can be updated in real time according to the related data of the train received by the service end.

[0061] The service end 102 can subscribe to data in real time. The service end 102 updates the data in two forms. When the data subscribed by the service end in the database changes, the database pushes the changed data to the service end. Alternatively, every ten minutes, the database pushes all the subscribed data to the service end. The service end receives the data and stores the data in the buffer according to the train identifier.

[0062] In this way, the service end 102 can send the running data of the corresponding train to the display end 101 based on the train identifier carried in the request information sent by the display end 101. Therefore, the display end 101 can be explained according to the display tracking method of the train moving position mentioned in the following examples.

[0063] Figure 2 A flowchart of a train moving position display tracking method provided by the embodiment of the application is shown in FIG. 1. Figure 2 As shown, the method can include the following steps.

[0064] S201, obtaining the current round running data of a target train according to a train identifier of the target train.

[0065] The current round running data includes a current round real track identifier where the target train runs and a current round real track position proportion.

[0066] Exemplarily, the display end can determine the target train in response to the preset train timetable or in response to the train adding operation of the staff, and then can generate the current round request information according to the train identification of the target train, and send the current round request information to the service end. If the target train has been displaced relative to the previous round, the service end can read the current round running data of the target train from the cache based on the train identification of the target train carried in the current round request information.

[0067] According to the above description, the train data sensor related to the target train is in communication connection with the service end, and the related data of the target train such as the speed and the real track currently running on can be obtained in real time. The service end can further determine the real track identification and the position information on the real track of the target train currently located according to the related data of the target train obtained, and determine the real track position ratio according to the position information on the real track and the length of the real track. Based on this, if the target train has been displaced relative to the previous round on the real track, the service end can send the current real track identification and the current real track position ratio of the target train running to the display end.

[0068] S202, determining the icon display position of the target train according to the current round running data and the previous round running data of the target train, the attribute parameter of the virtual track corresponding to the real track identification, and the preset animation running time.

[0069] The real track identification includes the current real track identification and / or the previous real track identification, and the attribute parameter of the virtual track at least includes the track length.

[0070] Exemplarily, the display end can store the running data of the target train obtained from the service end in the local in the form of key-value pairs. Then, the current real track identification in the current round running data and the previous real track identification in the previous round running data can be compared. If they are consistent, the current real track position ratio in the current round running data and the previous real track position ratio are compared. If they are consistent, it proves that the target train has not moved on the current track, and no subsequent processing is performed. If the current real track identification in the current round running data is consistent with the previous real track identification in the previous round running data, but the current real track position ratio in the current round running data is inconsistent with the previous real track position ratio, or the current real track identification in the current round running data is inconsistent with the previous real track identification in the previous round running data, it proves that the target train has moved on the track.

[0071] The present application mainly describes the phenomenon that the target train moves on the track. The movement information of the target train in the real track relative to the previous round can be determined according to the real track identifier and the real track position ratio in the current round of operation data of the target train, the real track identifier and the real track position ratio in the previous round of operation data. The movement information of the target train in the corresponding virtual track relative to the previous round is determined by combining the movement information of the target train in the real track relative to the previous round with the track length in the attribute parameter of the corresponding virtual track. Further, according to the movement information of the target train in the corresponding virtual track relative to the previous round, the movement time corresponding to the movement information, and the preset animation running time, the position points passed by the target train from the corresponding position of the previous round to the corresponding position of the current round on the corresponding virtual track can be determined. These position points passed are taken as the icon display positions. The preset animation running time can be set according to actual needs, which is not limited in the present application.

[0072] S203, display the train driving diagram of the target train according to the icon display position of the target train.

[0073] For example, after the icon display position of the target train is determined, the train driving diagram of the target vehicle can be obtained according to the vehicle identifier of the target vehicle, and the train driving diagram of the target vehicle is displayed on each icon display position. In this way, the moving position of the target train can be displayed and tracked on the urban rail transit monitoring interface.

[0074] In summary, in the display and tracking method of the train moving position provided by the present application, after the current round of operation data of the target train is obtained, the current round of operation data of the target train is combined with the previous round of operation data, and the movement information of the target train in the corresponding virtual track relative to the previous round is determined according to the track length included in the attribute parameter of the corresponding virtual track corresponding to the real track identifier. Further, according to the movement information of the target train in the corresponding virtual track relative to the previous round, the movement time corresponding to the movement information, and the preset animation running time, the position points passed by the target train from the corresponding position of the previous round to the corresponding position of the current round can be determined. These position points passed are taken as the icon display positions. Since the determined icon display positions are calculated according to the real-time movement data of the target train on the real track, the train driving diagram can appear on any position of the virtual track. When the train driving diagram of the target train is displayed on each icon display position, the smooth moving effect can be displayed on the virtual track during the movement of the target train, that is, the accurate position of the target train can be displayed in real time on the interface of the display end, that is, the moving position of the train can be tracked with high accuracy.

[0075] Meanwhile, the phenomenon of overlapping of train number windows of two trains is avoided in the case of shortening the interval time between the two trains.

[0076] Figure 3 Another flowchart of a display and tracking method of a train moving position is provided for the embodiments of the present application. Optionally, as shown in Figure 3 determining a to-be-displayed position of an icon of the target train according to the current round running data and the previous round running data of the target train, attribute parameters of a virtual track corresponding to a real track identity, and a preset animation running time, includes:

[0077] S301, determining whether a current round real track identity included in the current round running data is consistent with a previous round real track identity included in the previous round running data.

[0078] S302, if the current round real track identity is consistent with the previous round real track identity, determining a current round to-be-moved position according to a current round real track position ratio included in the current round running data and a track length of a virtual track corresponding to the current round real track identity.

[0079] It can be understood that the running data of the target train obtained by the display end includes a real track identity, and then the current round real track identity included in the obtained current round running data can be compared with the previous round real track identity included in the locally stored previous round running data to determine whether the current round real track identity is consistent with the previous round real track identity.

[0080] If the current round real track identity is consistent with the previous round real track identity, it proves that the target train runs on the same track in the current round and the previous round, and then the track length of the virtual track corresponding to the current round real track identity can be determined according to the correspondence between the real track and the virtual track, and the current round to-be-moved position is obtained by multiplying the track length of the virtual track corresponding to the current round real track identity and the current round real track position ratio, the current round to-be-moved position is used to indicate a position coordinate to which the target train will move on the virtual track.

[0081] S303, determining a to-be-displayed position of an icon of the target train according to the current round to-be-moved position, a previous round to-be-moved position corresponding to the previous round to-be-moved position, and a preset animation running time.

[0082] It can be understood that the determination process of the previous round to-be-moved position corresponding to the previous round to-be-moved position is similar to the determination process of the current round to-be-moved position, which will not be described here.

[0083] For example, after the current round to-be-moved position and the previous round to-be-moved position are determined, a moving distance of the target train in the current round relative to the previous round can be obtained, and the moving distance is divided based on a moving time corresponding to the moving distance and the preset animation running time to obtain a plurality of position points, and each position point is taken as a to-be-displayed position of an icon of the target train.

[0084] Figure 4 A flowchart of another method for displaying and tracking the moving position of a train is provided in the embodiments of the present application. Optionally, as shown in Figure 4 The method can further include:

[0085] S401, if the current real track identification is inconsistent with the previous real track identification, determining whether the proportion of the previous real track position included in the previous round of operation data is greater than or equal to a preset threshold value.

[0086] S402, if not, subtracting the preset threshold value from the proportion of the previous real track position to obtain a real track supplementary position proportion corresponding to the previous real track identification.

[0087] It can be understood that if the current real track identification is inconsistent with the previous real track identification, it proves that the target train is not running on the same track in the current round and the previous round, and then it is determined whether the proportion of the previous real track position is equal to the preset threshold value. If the preset threshold value is 100%, it is determined whether the target train moves to the end of the real track corresponding to the previous real track identification in the previous round. It should be noted that the preset threshold value can be set according to actual needs, and the present application does not limit it.

[0088] If the target train does not run to the position corresponding to the preset threshold value of the real track corresponding to the previous real track identification in the previous round, the preset threshold value can be subtracted from the proportion of the previous real track position, and the subtraction result is used as the real track supplementary position proportion corresponding to the previous real track identification.

[0089] S403, determining the icon display position of the target train according to the real track supplementary position proportion corresponding to the previous real track identification, the previous moving position corresponding to the proportion of the previous real track position, the current real track position, the current real track identification and the track length of the virtual track corresponding to the previous real track identification and the previous real track identification, and the preset animation running time.

[0090] For example, after the real track supplementary position proportion corresponding to the previous real track identification is determined, the moving distance of the target train on the virtual track corresponding to the previous real track identification can be determined according to the real track supplementary position proportion corresponding to the previous real track identification, the track length of the corresponding virtual track and the previous moving position corresponding to the proportion of the previous real track position. The moving distance of the target train on the virtual track corresponding to the current real track identification is determined according to the current real track position and the track length of the virtual track corresponding to the current real track identification.

[0091] According to the moving distance of the target train on the virtual track corresponding to the real track identification in the previous round, the moving distance of the target train on the virtual track corresponding to the real track identification in the current round, the moving time corresponding to the moving distance, and the preset animation running time, the icon display position of the target train on the virtual track corresponding to the real track identification in the previous round and the icon display position of the target train on the virtual track corresponding to the real track identification in the current round are determined.

[0092] Figure 5 Another flowchart of a display and tracking method of a train moving position provided by an embodiment of the present application is provided. Alternatively, the icon display position of the target train is determined according to the real track supplement position ratio corresponding to the real track identification in the previous round, the moving position in the previous round corresponding to the real track position ratio in the previous round, the real track position ratio in the current round, the real track identification in the current round, the track length of the virtual track corresponding to the real track identification in the previous round and the real track identification in the previous round, and the preset animation running time, and includes the following steps.

[0093] S501, determining the first moving position in the current round corresponding to the real track identification in the previous round according to the real track supplement position ratio corresponding to the real track identification in the previous round and the track length of the virtual track.

[0094] S502, determining the second moving position in the current round corresponding to the real track identification in the current round according to the real track position ratio in the current round and the track length of the virtual track corresponding to the real track identification in the current round.

[0095] For example, the real track supplement position ratio corresponding to the real track identification in the previous round is multiplied by the track length of the virtual track, and the multiplication result is taken as the first moving position in the current round corresponding to the real track identification in the previous round. The real track position ratio in the current round is multiplied by the track length of the virtual track corresponding to the real track identification in the current round, and the multiplication result is taken as the second moving position in the current round corresponding to the real track identification in the current round.

[0096] S503, determining the icon display position of the target train according to the first moving position in the current round, the second moving position in the current round, the moving position in the previous round corresponding to the real track position ratio in the previous round, and the preset animation running time.

[0097] Optionally, the first to-be-moved position in the current round is subtracted from the previous round moving position corresponding to the real track position proportion in the previous round, to obtain a to-be-moved distance of the target train; an icon to-be-displayed position of the target train on the virtual track corresponding to the real track identifier in the previous round is determined according to the to-be-moved distance, a moving time corresponding to the to-be-moved distance, and an animation running time; and an icon to-be-displayed position of the target train on the virtual track corresponding to the real track identifier in the current round is determined according to the second to-be-moved position in the current round, a moving distance corresponding to the second to-be-moved position, and the animation running time.

[0098] According to the subtraction result of the first to-be-moved position in the current round and the previous round moving position corresponding to the real track position proportion in the previous round, and the animation running time, the icon to-be-displayed position of the target train on the virtual track corresponding to the real track identifier in the previous round is determined, so that the moving animation of the target train on the virtual track corresponding to the real track identifier in the previous round is enriched to reach a preset threshold (such as 100%) of the animation amount.

[0099] It can be understood that the second to-be-moved position in the current round can represent a moving distance from the starting end of the virtual track corresponding to the real track identifier in the current round to the second to-be-moved position, and then according to the second to-be-moved position and the animation running time, the icon to-be-displayed position of the target train on the virtual track corresponding to the real track identifier in the current round is determined, so that the moving animation of the target train on the virtual track corresponding to the real track identifier in the current round starts from the starting end thereof.

[0100] Although the running data of the target train represents that the target train directly jumps from the previous real track to the next real track in the current round, the moving position of the target train can be displayed more finely by the above-mentioned manner, so that the train diagram of the target train displayed on the interface in the later period can smoothly slide from the virtual track corresponding to the previous real track to the virtual track corresponding to the next real track, and the moving position of the target train is tracked in real time.

[0101] Optionally, before determining the icon to-be-displayed position of the target train according to the current round running data and the previous round running data of the target train, the attribute parameters of the virtual track corresponding to the real track identifier, and the preset animation running time, the method can further include: detecting a drawing direction of the virtual track based on a reference drawing direction, to determine a virtual track not belonging to the reference drawing direction; converting the drawing direction of the virtual track not belonging to the reference drawing direction, and obtaining the attribute parameters of the virtual track according to initial parameters of the virtual track.

[0102] It can be understood that the virtual track drawn on the urban rail monitoring interface should have a unified reference drawing direction, but there can be a phenomenon of reverse running. Based on this, before determining the icon display position of the target train, the following processing needs to be performed first, which can improve the accuracy of the determined icon display position of the target train.

[0103] For example, each virtual track displayed on the interface has corresponding initial parameters, which include drawing direction, track angle and other information. Then, it can be detected whether the drawing direction of the virtual track is the reference drawing direction. If not, the initial parameters of the virtual track can be converted into attribute parameters of the virtual track based on the corresponding relationship between the drawing direction of the virtual track and the reference drawing direction.

[0104] Optionally, the above displaying the train running graph of the target train according to the icon display position of the target train includes: subtracting the icon display position of the target train from the length of the train running graph of the target train to obtain a target display target position of the target train; and displaying the train running graph of the target train at the target display target position of the target train based on the track angle corresponding to the target display target position of the target train.

[0105] It can be understood that the train running graph of the target train has a certain length. Then, the coordinates of the icon display position of the target train can be revised based on the length of the train running graph of the target train, and the train running graph of the target train is displayed at the target display target position of the target train obtained after the revision. In this way, the situation that the train running graph of the target train exceeds the virtual track when the target train runs on the virtual track can be avoided.

[0106] Further, each position point on the virtual track has a corresponding track angle. The track angle of the position point corresponding to the starting end and the track angle of the position point corresponding to the ending end on the virtual track can also be revised according to the track angles of the position points on the virtual track. Then, after the target display target position of the target train is determined, the track angles corresponding to each target display target position can be obtained, and the train running graph of the target train is displayed at each target display target position based on the track angles corresponding to each target display target position. In this way, the train running graph of the target train can be moved along the corresponding virtual track.

[0107] Optionally, the train running graph can include a plurality of graph elements. If the position coordinates of each graph element are absolute coordinates relative to the display interface, the position coordinates of each graph element can be first converted into relative coordinates relative to the train running graph. In this way, when the train running graph moves, each graph element on the train running graph also moves relatively.
