Description

Technical Field

[0001] The present application relates to the technical field of railway signal control, and in particular to a railway passenger broadcasting two-way channel fusion method and system thereof. Background Art

[0002] With the rapid development of railway technology, the scope of railway tracks is getting larger and larger. The current video surveillance system relies on fixed-point surveillance cameras to monitor specific locations. The picture is not clear and the cost is too high. In case of emergencies, it is impossible to feedback to the railway command center in time. Even if there are staff to handle it, the on-site situation cannot be clearly fed back to the command center. The command center does not understand the detailed situation on the scene and the specific location of the track workers. It can only communicate with the workers through walkie-talkies or mobile phones to conduct real-time command and dispatch work. Therefore, how to expand the scope of video surveillance while controlling costs, and how to timely and accurately feed back the on-site operation situation to the command center are important issues that need to be solved urgently.

[0003] Route management is a key point in modern railway passenger transport management. If the packages can be delivered to customers as quickly and safely as possible, and railway passenger trucks are more efficient in transportation and improve the input-output ratio, the company's weight in the eyes of customers will be greatly enhanced.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The terms "first", "second" and "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0044] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0045] At present, the demand of railway passenger stations is usually characterized by a series of departure signals, and the driving trajectory is also summarized by extracting a series of convergence broadcast signals to establish a fusion library of the railway passenger station and the driving trajectory. Then, by performing relational operations on the departure signals and convergence broadcast signals, and based on the operation results, the driving trajectory that matches the departure signal is locked. However, this method is difficult to apply to scenarios with rapid fusion changes. The transmitted driving trajectory often has a low match with the demand of railway passenger stations, and the service quality of railway passenger stations is poor. However, this method also has the following problems: If the fusion value at the railway passenger station end and the fusion value at the article end are not strictly equal, or the distance is close, then there will be a situation where there is no match, and the recommendation algorithm cannot recall the results or has the disadvantage of low recall accuracy.

[0046] In response to the above technical problems, the present invention provides a railway passenger broadcast two-way channel fusion method, system, system and storage medium, which can adapt to application scenarios where departure signals and merging broadcast signals frequently change, so that the transmitted track switching signals are more matched with the needs of railway passenger stations, and the service quality of railway passenger stations is better. Figure 1FIG. 1 is a schematic diagram showing a principle of an application scenario of a method for fusion of two-way channels of railway passenger broadcasting according to the present invention. Figure 1 As shown, it includes a server 10 and a railway passenger station dispatching device 20. When the railway passenger station dispatching device 20 establishes contact with the server 10, the server 10 can collect the dispatching device ID used by the railway passenger station and / or the railway passenger station account through the railway passenger station dispatching device 20. Then, based on the identification features of the railway passenger station, the server 10 can extract the directed relationship graph of the departure signal and the convergence broadcast signal of the railway passenger station from the fusion signal library. Then, based on the directed relationship graph, the server 10 can use the signal corresponding to the convergence broadcast signal with the top P correlation in the directed relationship graph as the track switching signal, and transmit it to the railway passenger station dispatching device 20; P is an integer greater than 0. At the same time, the railway passenger station dispatching device 20 can collect the road conditions between the railway passenger station and the driving track, such as the driving track being monitored by the railway passenger station, the driving track being recorded by the railway passenger station, and the driving track being complained by the railway passenger station. The server 10 can change the directed relationship graph of the departure signal and the merging broadcast signal in real time based on the road conditions between the railway passenger station and the driving trajectory. In addition, the server 10 can also set a new departure signal, and / or a new merging broadcast signal. In some application scenarios, the railway passenger station can independently select or configure fusion after entering the client 20. In other application scenarios, the server 10 generates fusion based on the behavior of the railway passenger station, or collects fusion features corresponding to the railway passenger station from a third party. Then, the server 10 changes the directed relationship graph of the departure signal and the merging broadcast signal of the railway passenger station in the fusion signal library. For the specific implementation process, please refer to the description of the embodiment, which will not be repeated here.

[0047] The above method is applied to adapt to the application scenario where departure signals and merging broadcast signals change frequently, so that the transmitted track switching signal is more matched with the needs of the railway passenger station, and the service quality of the railway passenger station is improved.

[0048] The following specific embodiments are used to describe in detail the technical solutions of the present invention and how the technical solutions of the present application solve the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0049] Figure 2 The flowchart of the railway passenger broadcasting two-way channel fusion method provided in the first embodiment of the present invention is as follows: Figure 2 As shown, the method in this embodiment may include:

[0050] S101. Collect a directed relationship graph of departure signals and merging broadcast signals of a railway passenger station.

[0051] In this embodiment, the server can collect identification features of the railway passenger station, and the identification features include: the dispatching equipment ID used by the railway passenger station, and / or the railway passenger station account; based on the identification features of the railway passenger station, extract the directed relationship graph of the departure signal and the merging broadcast signal of the railway passenger station from the fusion signal library; wherein, the departure signal is used to describe the characteristics of the railway passenger station, and the merging broadcast signal is used to describe the driving trajectory characteristics.

[0052] Specifically, there are directed relationship graphs between departure signal 1, departure signal 2, departure signal 3, departure signal 4 and convergence broadcast signal 1, convergence broadcast signal 2, convergence broadcast signal 3, convergence broadcast signal 4, convergence broadcast signal 5, convergence broadcast signal 6, convergence broadcast signal 7, and convergence broadcast signal 8. Specifically, taking departure signal 1 as an example, it can be seen that departure signal 1 is associated with convergence broadcast signal 1, convergence broadcast signal 2, and convergence broadcast signal 3, and departure signal 1 is more strongly associated with convergence broadcast signal 2.

[0053] It should be noted that this embodiment does not limit the driving track and division rules of the departure signal, and those skilled in the art can reasonably set the driving track and division rules of the departure signal based on actual conditions. At the same time, this embodiment does not limit the driving track and division rules of the convergence broadcast signal, and those skilled in the art can reasonably set the driving track and division rules of the convergence broadcast signal based on actual conditions.

[0054] S102: Based on the directed relationship graph, a track switching signal is transmitted to a dispatching device of a railway passenger station.

[0055] In this embodiment, based on the directed relationship graph, the server can use the signal corresponding to the convergence broadcast signal with the top P correlation in the directed relationship graph as the track switching signal, and transmit it to the dispatching equipment of the railway passenger station; P is an integer greater than 0. The directed relationship graph is based on the real-time changes in the road conditions between the railway passenger station and the driving track.

[0056] Specifically, the same railway passenger station may have one or more departure signals to describe multiple features of the railway passenger station in different fields or the same field. The server may use the signal corresponding to the convergence broadcast signal with the top P correlation in the directed relationship graph as a track switching signal and transmit it to the dispatching equipment of the railway passenger station. At the same time, the server may also establish a new association between the departure signal and the convergence broadcast signal based on the directed relationship graph of the real-time change of road conditions between the railway passenger station and the driving trajectory, or adjust the degree of association between the departure signal and the convergence broadcast signal. For example, the correlation between the departure signal and the convergence broadcast signal can be changed from any one or more of the number of ingress and egress of the railway passenger station, the length of stay at the railway passenger station, and the number of complaints at the railway passenger station. If the driving trajectory is monitored by the railway passenger station, the correlation score is +P; if the driving trajectory is recorded by the railway passenger station, the correlation score is +x; if the driving trajectory is complained by the railway passenger station, the correlation score is -y. The correlation score can be adjusted according to the actual business situation. In addition to directly setting the scores for each item, you can also calculate the scores by setting the weights of each behavior. For example, different weights can be set for the vehicle trajectory being monitored by the railway passenger station, the vehicle trajectory being recorded by the railway passenger station, and the vehicle trajectory being complained by the railway passenger station. Then, based on the weighted calculation, the correlation between the departure signal and the convergence broadcast signal can be obtained, thereby changing the directed relationship graph in real time.

[0057] It should be noted that this embodiment does not limit the change rules of the directed relationship graph of the departure signal and the convergence broadcast signal. Those skilled in the art can reasonably set the change rules based on the actual situation, so as to change the directed relationship graph in real time. For example, the score value of the behavior can be directly set, or the weight of each behavior can be set to calculate the score.

[0058] In this embodiment, a directed relationship graph of the departure signal and the convergence broadcast signal of the railway passenger station is collected; based on the directed relationship graph, a track switching signal is transmitted to the dispatching equipment of the railway passenger station; wherein the directed relationship graph is based on the real-time changes in the road conditions between the railway passenger station and the driving track. Thus, it can adapt to the application scenarios where the departure signal and the convergence broadcast signal change frequently, so that the transmitted track switching signal is more matched with the needs of the railway passenger station, and the service quality of the railway passenger station is better.

[0059] Figure 3 The flowchart of the railway passenger broadcasting two-way channel fusion method provided in the second embodiment of the present invention is as follows: Figure 3 As shown, the method in this embodiment may include:

[0060] S201. Setting a new departure signal and / or a new convergence broadcast signal.

[0061] In this embodiment, the server can also set a new departure signal and / or a new convergence broadcast signal. In some application scenarios, the railway passenger station can independently select or configure the fusion after entering the client. In other application scenarios, the background server generates the fusion based on the railway passenger station behavior, or collects the corresponding fusion features of the railway passenger station from a third party.

[0062] S202. Change the directed relationship graph of the departure signals and the merging broadcast signals of the railway passenger station in the fusion signal library.

[0063] In this embodiment, if a departure signal changes, the correlation between the new departure signal and each merging vehicle broadcast signal is collected; based on the correlation between the new departure signal and each merging vehicle broadcast signal, a directed relationship graph between the new departure signal and the merging vehicle broadcast signal is established; if a merging vehicle broadcast signal changes, the correlation between the new merging vehicle broadcast signal and each departure signal is collected; based on the correlation between the new merging vehicle broadcast signal and each departure signal, a directed relationship graph between the new merging vehicle broadcast signal and the departure signal is established; the directed relationship graph between the new departure signal and the merging vehicle broadcast signal, and / or the directed relationship graph between the new merging vehicle broadcast signal and the departure signal is configured in the fusion signal library.

[0064] Specifically, the overlap between the current fusion and the fused route is calculated, the top P (P can be customized), and the fusion with the strongest correlation is selected to establish an association relationship, thereby establishing an initial directed relationship graph for each current fusion. If there is no similar fusion, it will not be associated for the time being. After going online, it will be associated with the fusion that interacts with the driving trajectory (railway passenger station) that has the current fusion for the first time. Clustering algorithms, classification algorithms, etc. can be used to calculate the overlap between the current fusion and the fused route. The calculation of the overlap between the current fusion and the fused route is a prior art and will not be repeated here.

[0065] Take the change of the convergence broadcast signal as an example to illustrate. For example, the current convergence broadcast signal 8, after calculating the driving route overlap, the convergence broadcast signal 8 and the top 3 driving route overlaps with other convergence broadcast signals are merged into: convergence broadcast signal 3, convergence broadcast signal 6 and convergence broadcast signal 2. Then, combined with the directed relationship graph of the departure signal and the convergence broadcast signal, the initial directed relationship graph between the convergence broadcast signal 8 and the departure signal can be established. The convergence broadcast signal 8 is associated with the departure signal 1 and the departure signal 3, and the degree of association between the convergence broadcast signal 8 and the departure signal 3 is relatively strong. Finally, the directed relationship graph of the new convergence broadcast signal and the departure signal can be configured into the fusion signal library.

[0066] When the departure signal changes, the implementation principle is the same as the change of the convergence broadcast signal, which will not be repeated here.

[0067] Assume that the current j-th convergence vehicle broadcast signal A j The i-th departure signal U associated with i The correlation between R(U i A j ) can be calculated using the following formula:

[0068] R(U i A j )=ΣD(A i A j )*R(U i A i ), (i, j∈1, 2, 3...P)

[0069] Among them, D(A i A j ) is the overlap between the driving routes of the i-th and j-th merging broadcast signals, R(U i A i ) is the correlation between the i-th convergence broadcast signal and the i-th departure signal.

[0070] Similarly, the current departure signal U j The i-th convergence broadcast signal A associated with i The correlation between R(A i U j ) can be calculated using the following formula:

[0071] R(A i U j )=ΣD(U i U j )*R(A i U i ), (i, j∈1, 2, 3...P)

[0072] Among them, D(U i U j ) is the overlap between the driving routes of the i-th departure signal and the j-th departure signal, R(A i U i ) is the correlation between the i-th convergence broadcast signal and the i-th departure signal.

[0074] S204: Based on the directed relationship graph, a track switching signal is transmitted to a dispatching device of a railway passenger station.

[0075] In this embodiment, the specific implementation process and technical principles of steps S203 to S204 can be found in Figure 2The relevant descriptions in steps S101 to S102 in the method shown are not repeated here.

[0076] In this embodiment, a directed relationship graph of the departure signal and the convergence broadcast signal of the railway passenger station is collected; based on the directed relationship graph, a track switching signal is transmitted to the dispatching equipment of the railway passenger station; wherein the directed relationship graph is based on the real-time changes in the road conditions between the railway passenger station and the driving track. Thus, it can adapt to the application scenarios where the departure signal and the convergence broadcast signal change frequently, so that the transmitted track switching signal is more matched with the needs of the railway passenger station, and the service quality of the railway passenger station is better.

[0077] In addition, this implementation can also set new departure signals and / or new convergence broadcast signals; change the directed relationship graph of the departure signals and convergence broadcast signals of the railway passenger station in the fusion signal library. This can adapt to the application scenarios where departure signals and convergence broadcast signals change frequently, so that the transmitted track switching signals are more compatible with the needs of the railway passenger station, and the service quality of the railway passenger station is better.
