[0027] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Apparently, the described embodiments are some, but not all, of the 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 efforts shall fall within the protection scope of the present application.

[0028] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist simultaneously, and B exists alone, where A and B may be singular or plural. In the written description of the present application, the character " / " generally represents an "or" relationship between the associated objects before and after.

[0029] The technical solutions provided by the embodiments of the present application can be applied to scenarios such as train arrival and guide information display, public information release, emergency information release, and advertisement broadcast. In these scenarios, the passenger information system plays the layout images required for the scenarios through a broadcast controller.

[0030] When playing the layout images required for the scenarios through the broadcast controller, the passenger information system forwards the relevant information of the layout images expected to be displayed to the broadcast controller through the station system, so that the broadcast controller plays the layout images according to the relevant information of the layout images expected to be displayed for passengers to view.

[0031] Among them, the passenger information system is a modern information service platform integrating multimedia network technology and computer technology, designed specifically for passengers of public transportation, especially urban rail transit. It real-time transmits information, etc. through various media such as broadcast controllers at fixed positions in the station, such as liquid crystal display (LCD) devices or light emitting diode (LED) displays, on-vehicle displays, and mobile device applications.

[0032] However, using the above method, if the station system cannot work properly, such as being abnormal or offline, the passenger information system will be unable to communicate with the station system. Therefore, the passenger information system cannot send the relevant information of the layout images expected to be displayed to the station system, resulting in the broadcast controller being unable to play the layout images.

[0033] To solve the problem in the prior art that if the station system fails to work properly, the playback controller cannot play the layout image, and thus ensure the normal playback of the layout image, the embodiment of the present application provides a method for playing a layout image. The passenger information system can first store the relevant information of the layout image to be played in a distributed file system, and send the corresponding storage path information to the playback controller, so that the playback controller can obtain the relevant information of the layout image to be played from the distributed file system based on the storage path information, and generate a corresponding target layout image for playback. Storing the relevant information of the layout image to be played in the distributed file system in this way, enabling the playback controller to obtain the relevant information of the layout image to be played from the distributed file system based on the storage path information, and generating a corresponding target layout image for playback, not only makes the acquisition of relevant information no longer dependent on the station system, but also the distributed file system usually stores the relevant information on different nodes through replication and caching mechanisms, ensuring the high reliability of data storage. Therefore, the problem in the prior art that if the station system fails to work properly, the playback controller cannot play the layout image can be effectively solved, thus ensuring the normal playback of the layout image.

[0034] Next, the method for playing a layout image provided by the present application will be described in detail through the following several specific embodiments. It can be understood that these several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0035] Figure 1 It is a schematic flowchart of a method for playing a layout image provided by an embodiment of the present application, which is applied to a playback controller. Exemplarily, please refer to Figure 1 As shown, the method for playing a layout image may include: S101. Receive the storage path information sent by the passenger information system.

[0036] In order not to rely on the station system to forward the relevant information of the layout image expected to be played by the passenger information system, and thus ensure the normal playback of the layout image, in the embodiment of the present application, after obtaining the relevant information of the layout image expected to be played, the passenger information system can store the relevant information in a distributed file system, and directly send the storage path information of the relevant information in the distributed file system to the playback controller, realizing real-time communication with the playback controller, so that the playback controller can quickly respond to the passenger information system, and based on the storage path information, obtain the relevant information of the layout image expected to be played by the passenger information system from the distributed file system, that is, execute the following S102.

[0037] Exemplarily, in the embodiments of the present application, when the passenger information system obtains the relevant information of the layout image to be played, in one possible implementation manner, it may receive a drag operation input by the user; and in response to the drag operation, determine the relevant information of the layout image to be played; in another possible implementation manner, it may receive a selection operation of the user for the relevant information of multiple preset layout images to be played, and in response to the selection operation, determine the relevant information of the currently desired layout image from the relevant information of the multiple preset layout images to be played, etc., which can be specifically set according to actual needs.

[0038] It can be understood that in the embodiments of the present application, after the passenger information system obtains the relevant information of the layout image to be played, by storing the relevant information in the distributed file system and sending the storage path information of the relevant information in the distributed file system to the broadcast controller, the broadcast controller can obtain the relevant information of the layout image to be played from the distributed file system based on the storage path information. This not only makes the acquisition of relevant information no longer dependent on the station system, but also the distributed file system usually stores the relevant information on different nodes through replication and caching mechanisms. Even if one of the nodes is abnormal, the broadcast controller can still obtain the relevant information from other nodes, ensuring the high reliability of data storage. Therefore, by adopting the technical solution provided by the present application, the problem in the prior art that the broadcast controller cannot play the layout image when the station system fails to work properly can be effectively solved, thus ensuring the normal playback of the layout image.

[0039] S102. Based on the storage path information, obtain the relevant information of the layout image expected to be played by the passenger information system from the distributed file system, where the relevant information includes elements in the layout image expected to be played and attribute files of the elements.

[0040] Exemplarily, the elements may include pictures, videos, text boxes, route maps, etc., which can be specifically set according to actual needs.

[0041] Exemplarily, the attribute files of the elements may include the color, shape, size, and coordinate position of the elements, etc., for generating the corresponding target layout image subsequently.

[0042] Among them, the color attribute of an element determines its color performance in the layout image. Different colors can convey different emotions and atmospheres, having an important impact on the overall visual effect. The shape attribute of an element determines its appearance in the layout image. The shape can be a simple geometric figure, or a complex pattern or icon. The choice and arrangement of shapes can affect the overall layout and visual effect of the layout. The size attribute of an element determines its size in the layout image. The choice of size can affect the prominence and visual impact of the element, thus guiding the viewer's line of sight and attention. The position of an element is usually directly related to the coordinates, determining its relative relationship with other elements, and thus affecting the overall layout and visual effect.

[0043] Exemplarily, in the embodiments of the present application, the relevant information may include, in addition to the elements and attribute files of the elements in the layout image to be played as expected, the playback time of the layout image, etc., and can be specifically set according to actual needs.

[0044] After obtaining the relevant information of the layout image expected to be played by the passenger information system from the distributed file system based on the storage path information, the following S103 can be executed.

[0045] S103. Generate a corresponding target layout image based on the elements and attribute files of the elements in the layout image expected to be played, and play the target layout image.

[0046] Exemplarily, when generating a corresponding target layout image based on the elements and attribute files of the elements in the layout image expected to be played, a native JavaScript method can be used to generate the corresponding target layout image; or a layout image generation tool, etc. can be used to generate the corresponding target layout image, and can be specifically set according to actual needs.

[0047] It can be seen that in the embodiment of the present application, the broadcast controller receives the storage path information sent by the passenger information system; based on the storage path information, it obtains the relevant information of the layout image expected to be played by the passenger information system from the distributed file system, and the relevant information includes the elements in the layout image expected to be played and the attribute files of the elements; based on the elements in the layout image expected to be played and the attribute files of the elements, it generates a corresponding target layout image and plays the target layout image. In this way, the relevant information of the layout image expected to be played is stored in the distributed file system, so that the broadcast controller obtains the relevant information of the layout image expected to be played from the distributed file system based on the storage path information, and generates a corresponding target layout image for playing. This not only makes the acquisition of relevant information no longer dependent on the station system, but also the distributed file system usually stores the relevant information on different nodes through replication and caching mechanisms, ensuring the high reliability of data storage. Therefore, it can effectively solve the problem in the prior art that if the station system cannot work properly, the broadcast controller cannot play the layout image, thus ensuring the normal playback of the layout image.

[0048] Based on the above Figure 1 illustrated embodiment, exemplarily, in the above S102, when obtaining the relevant information of the layout image expected to be played by the passenger information system from the distributed file system based on the storage path information, the specific implementation can refer to the following Figure 2 illustrated embodiment.

[0049] Figure 2 It is a schematic flowchart of a method for obtaining the relevant information of the layout image expected to be played by the passenger information system from the distributed file system provided by the embodiment of the present application. Exemplarily, please refer to Figure 2 shown. The method may include: S201. Based on the storage path information, obtain the target compressed package corresponding to the layout image expected to be played by the passenger information system from the distributed file system.

[0050] Exemplarily, in the embodiment of the present application, after the passenger information system obtains the relevant information of the layout image expected to be played, it can compress the relevant information, compress it into a target compressed package, and store the obtained target compressed package in the distributed file system. In this way, by storing the target compressed package in the distributed file system, the broadcast controller can not only obtain complete relevant information, ensuring the integrity of the relevant information obtained by the broadcast controller; but also reduce the folder size and improve the acquisition efficiency of the relevant information.

[0051] Exemplarily, when the passenger information system compresses the relevant information of the layout image it expects to play, it can use professional software or online tools, such as Adobe Photoshop, online web platforms such as "i Compression" or "iyasuo", etc., to compress the relevant information of the layout image it expects to play; it can also use compression algorithms, such as wavelet transform, Huffman coding, etc., to compress the relevant information of the layout image it expects to play, and specific settings can be made according to actual needs.

[0052] S202. Parse the target compressed package to obtain the relevant information of the layout image expected to be played.

[0053] Combined with the above description, the player can, based on the storage path information, obtain the target compressed package corresponding to the layout image expected to be played by the passenger information system from the distributed file system; and parse the target compressed package to obtain the relevant information of the layout image expected to be played. In this way, by parsing and obtaining the relevant information of the layout image expected to be played through the target compressed package, the broadcast controller can not only obtain complete relevant information, ensuring the integrity of the relevant information obtained by the broadcast controller; but also reduce the folder size and improve the acquisition efficiency of the relevant information.

[0054] Based on any of the above embodiments, exemplarily, in the embodiments of the present application, the relevant information may further include the playing time of the layout image expected to be played.

[0055] In the case where the relevant information further includes the playing time of the layout image expected to be played, the target layout image can be played based on the playing time for the passengers to view.

[0056] It can be understood that if the relevant information does not include the playing time of the layout image expected to be played, after the player generates the corresponding target layout image based on the elements and attribute files of the layout image expected to be played, the target layout image can be directly played; or, the target layout image can also be played based on the pre-configured playing time, etc., and specific settings can be made according to actual needs.

[0057] Figure 3 It is a schematic flowchart of another method for playing a layout image provided by the embodiments of the present application, which is applied to the passenger information system. Exemplarily, please refer to Figure 3 As shown, the method for playing the layout image may include: S301.

[0059] S303. Send the storage path information of the relevant information in the distributed file system to the broadcast controller; wherein, the storage path information is used to instruct the broadcast controller to obtain the relevant information from the distributed file system, generate a corresponding target layout image based on the elements and the attribute files of the elements in the layout image to be played as expected in the relevant information, and play the target layout image.

[0060] Exemplarily, in the embodiments of the present application, the relevant information further includes the playing time of the layout image to be played as expected. Storing the relevant information in the distributed file system includes: Compress the elements, the attribute files of the elements, and the playing time in the layout image to be played as expected to obtain a target compressed package; Store the target compressed package in the distributed file system.
