NAS (Network Attached Storage ) is a dedicated data storage server that can provide cross-platform file sharing functionality. Based on the NAS function, the file of the mobile terminal can be transmitted to the display device across the network. In synchronizing files to a display device, a mobile terminal may have the following scenarios: the mobile terminal does not synchronize files to the display device; in the last synchronization, the mobile terminal leaves the network range of the display equipment, and the like, so that the synchronization is interrupted; after the last synchronization, the mobile terminal stores a newly added file; the mobile terminal resumes factory shipment or uninstalls the service for synchronization; the mobile terminal stores continuous photos, which results in a plurality of different files at the same time point. For these cases, there is no reliable standard in the related art to determine from which file to start synchronization and from which direction to synchronize the files, but to repeatedly synchronize all files each time, resulting in resource waste and low synchronization efficiency.

In order to solve the above-mentioned problems, an embodiment of the present application provides a file synchronization system, which includes a mobile terminal 300A and a display device 200, where a file in the mobile terminal is transmitted to a NAS hard disk through a network, as in a frame schematic of the file synchronization system shown in fig. 6, where the file synchronization system shown in fig. 6 may be used to transmit file data based on a wide area network or may be used to transmit file data based on a local area network. The display device 200 includes a file receiving server 200A and a NAS hard disk 200B, where the file receiving server and the NAS hard disk may be integrated inside the display device, or may be used as an external device after being connected to the display device.

Here, the file receiving server 200A may include a data server, which is an ESS server (Enterprise Storage Server ) by which file data is transferred between the mobile terminal 300A and the hard disk 200B, and a message server. The message server is an MQTT server (Message Queuing Telemetry Transport, message queue telemetry transport), through which messages, such as timestamp information of a file, are transferred between the mobile terminal 300A and the hard disk 200B. Specifically, the mobile terminal 300A synchronizes the file to the hard disk 200B through the ESS server, and simultaneously synchronizes the timestamp information and the file name information of the file to the hard disk 200B through the MQTT server. The mobile terminal 300A may also acquire the timestamp information and the file name information of the file stored in the hard disk 200B from the hard disk 200B through the MQTT server.

In the embodiment of the application, the mobile terminal needs to be connected with the display device first, and after the mobile terminal and the display device establish communication, the display device detects whether the mobile terminal is authorized. If not, the mobile terminal actively pushes an authorization request to the display device to obtain the authorization of the display device. And after receiving the request, the display equipment authorizes the mobile terminal to perform the action of synchronizing the file to the display equipment according to the actual situation. Each display device can authorize a plurality of mobile terminals at the same time, and each mobile terminal can be authorized by a plurality of display devices, but each mobile terminal can only synchronize files to the same display device at the same time. The mobile terminal can automatically synchronize the file to the display device each time the display device is found to be in succession.

For example, as shown in fig. 7, after the mobile terminal and the display device are connected to the same WI-FI or hot spot, the two-dimensional code of the display device related to the home private cloud application is scanned by using the scanning function of WeChat, the two-dimensional code is scanned to automatically send an authorization request to the display device, and after the display device authorizes the mobile terminal, the home private cloud application applet is opened on the mobile terminal, as shown in fig. 8, to gather the looking-at applet application interface. The user may select all files to be synchronized to the display device through the glowing applet application interface. After authorizing the mobile terminal for the display device, the mobile terminal automatically synchronizes files to the display device.

In this embodiment of the present application, the file receiving server maintains a time axis of a synchronous file for each mobile terminal device, and, as illustrated in fig. 9, the time stamp of the file is the time generated by the mobile terminal with the file itself, and, for example, the photographing time may be taken as the time stamp of the file, or the time shared from other devices may be taken as the time stamp of the file, so each file has a unique time stamp (here, the special case of continuously shooting files is not considered first), and each file may be marked uniquely on the time axis shown in fig. 9.

After the mobile terminal establishes connection with the display device and obtains authorization, the mobile terminal can automatically synchronize files with the display device. The mobile terminal may obtain a timestamp of the file synchronized to the display device from the display device, and based on the timestamp, synchronize only the unsynchronized file to the display device, i.e., synchronize only the display device with a timestamp that is not equal to the timestamp of the file the mobile terminal has synchronized to the display device. The file receiving server can only receive the unsynchronized file. Therefore, the synchronized files do not need to be repeatedly synchronized, resource waste is avoided, and the synchronization efficiency is improved.

As shown in fig. 9, the mobile terminal stores 8 files, i.e., files a to H8 files, and files D to H are files synchronized to the display device, and the time axis maintained by the file server is marked with file D to H file time stamps Td to Th.

In some embodiments, the mobile terminal does not synchronize files to the display device, and the file server maintains a timeline for the mobile terminal without marking any time stamps. The files stored in the mobile terminal are all unsynchronized files. The mobile terminal can synchronize the file directly to the display device without determining whether a time stamp already exists. Specifically, the file is synchronized to the display device in a direction in which the time stamp gradually decreases from the file having the largest time stamp. Thus, if the process of synchronizing the files is performed, if the synchronous files are interrupted due to factors such as that the mobile terminal leaves the network range of the display device, the unsynchronized files are classified as original files when the synchronous files are restarted next time.

Illustratively, as shown in fig. 9, the mobile terminal stores 8 files, file a through file H, the 8 files have not been synchronized to the display device before, and any time axis is marked on the time axis maintained by the file server for the mobile terminal. The files A to H are all unsynchronized files, and when the mobile terminal synchronizes the files to the display device, the files are sequentially synchronized to the display device from the file H with the largest time stamp in the direction that the time stamp is gradually reduced. Thus, when the synchronization is interrupted, for example, at the file C, the files synchronized to the display device are the files D to H, and the files a to C are the original files in the mobile terminal. The embodiment can solve the problem of file synchronization in the scene that the mobile terminal does not synchronize files with the display device.

In the above embodiment, the timestamp with the largest timestamp value in the unsynchronized file received by the display device is recorded as the largest time point, and the timestamp with the smallest timestamp value in the unsynchronized file received by the display device is recorded as the smallest time point. For example, if in the synchronization, the synchronization is interrupted at the file C, the files synchronized to the display device are the files D to H, wherein the time stamp Td of the file D is the minimum time stamp, the time stamp Td is recorded as the minimum time point, the time stamp Th of the file H is the maximum time stamp, and Th is recorded as the maximum time stamp. In this way, when the files are synchronized next time, it can be directly determined that the files with the time stamp greater than the minimum time point are less than the maximum time point are the files already synchronized to the display device, and the mobile terminal does not need to synchronize the files to the display device.

In some embodiments, the mobile terminal obtains the recorded maximum time point and minimum time point from the display device when the file synchronized by the mobile terminal is stored in the display device. Comparing the file stored in the mobile terminal with the maximum time point and the minimum time point, and if an unsynchronized file exists and the time stamp of the unsynchronized file is smaller than the minimum time point, synchronizing the unsynchronized file to the display device in a direction in which the time stamp gradually decreases from the unsynchronized file with the largest time stamp.

For example, as shown in fig. 9, the mobile terminal synchronizes files D to H with the display device, the time stamps are Td to Th, the maximum time point acquired from the display device by the mobile terminal is Th, and the minimum time point is Td. Because the last synchronization is interrupted, the original files A to C are not synchronized to the display device, and the time stamp of all the unsynchronized files is smaller than the minimum time point Td, the mobile terminal starts from the file C with the largest time stamp in the unsynchronized files, and synchronizes the files to the display device in the direction that the time stamp is gradually reduced. If in this sub-synchronization the synchronization is interrupted at file a, file a is still the original file's category. In the uploading process, the file B and the file C are successfully synchronized into the display device, the time stamp Tb of the file B is smaller than the time stamp Tc of the file C, and the minimum time point on the time axis is updated to be the time stamp Tb of the file B. When the file synchronization process is performed again, the file to be synchronized is judged by the updated minimum time point Tb, namely the original file A is synchronized. The embodiment can solve the problem of file synchronization in a scene of synchronization interruption in synchronization.

In some embodiments, the mobile terminal obtains the recorded maximum time point and minimum time point from the display device when the file synchronized by the mobile terminal is stored in the display device. Comparing the file stored in the mobile terminal with the maximum time point and the minimum time point, and if an unsynchronized file exists and the time stamp of the unsynchronized file is larger than the maximum time point, synchronizing the unsynchronized file to the display device in a direction in which the time stamp gradually increases from the unsynchronized file with the minimum time stamp.

For example, as shown in fig. 9, the mobile terminal synchronizes files D to H with the display device, the time stamps are Td to Th, the maximum time point acquired from the display device by the mobile terminal is Th, and the minimum time point is Td. In this embodiment, the mobile terminal stores the new files I to K, and the time stamps of the new files I to K are Ti to Tk, where the time stamps Ti to Tk are all greater than the maximum time point Th. The mobile terminal synchronizes the files to the display device in the direction that the time stamp gradually increases from the file I with the smallest time stamp in the unsynchronized file I to the unsynchronized file K. If during this synchronization of the files, the synchronization is interrupted at file K, which is still the category of the newly added file. In the uploading process, the file I and the file J are successfully synchronized into the display device, the timestamp Tj of the file J is larger than the timestamp Ti of the file I, and the maximum time point on the time axis is updated to be the timestamp Tj of the file J. And when the file synchronization process is performed again, judging the file to be synchronized, namely the newly added file K, according to the updated maximum time point Tj. If the newly added file is stored in the mobile terminal continuously in the synchronization, the newly added file is continuously synchronized in the mode. The embodiment can solve the problem of file synchronization in the scene that the newly added file is stored in the mobile terminal.

In some embodiments, the mobile terminal obtains the recorded maximum time point and minimum time point from the display device when the file synchronized by the mobile terminal is stored in the display device. Comparing the file stored in the mobile terminal with the maximum time point and the minimum time point, if an unsynchronized file with a file time stamp greater than the maximum time point and an unsynchronized file with a file time stamp less than the minimum time point exist at the same time, firstly synchronizing the unsynchronized file with a time stamp greater than the maximum time point, and then synchronizing the unsynchronized file with a time stamp less than the minimum time point, or firstly synchronizing the unsynchronized file with a time stamp less than the minimum time point, and then synchronizing the unsynchronized file with a time stamp greater than the maximum time point. In a specific embodiment, refer to the process of synchronizing an original file and synchronizing a newly added file in the uploading embodiment.

In some embodiments, the file receiving server, when creating the timeline, marks the name of each file in addition to the timestamp of each file, illustratively files A-K having the names Fa-Fk.

In some embodiments, a timestamp file may be stored in the mobile terminal, for example, a continuous shooting file, where the continuous shooting file is a plurality of photos taken by the mobile terminal at the same time point. When the mobile terminal acquires the maximum time point and the minimum time point from the display device, if the file with the timestamp larger than the minimum time point and smaller than the maximum time point is directly judged to be the file synchronized to the display device, the continuous shooting file with the timestamp equal to the minimum time point or the maximum time point is omitted. Therefore, in the case where the file time stamp is equal to the minimum time point or equal to the minimum time point, the present embodiment further determines whether the name of the file is the same as the currently defined maximum time point corresponding file or the maximum time point corresponding file. If the file is different, the file needs to be further synchronized for continuous shooting.

For example, the files D to H are files synchronized in the display device in the mobile terminal, the name of the file D is Fd, the name of the file H is Fh, when the mobile terminal still has the file D1 with the timestamp equal to Td and the file name of Fd1, the file D1 is a continuous shooting file of the file D, and the mobile terminal synchronizes the file D1 to the display device. Or when the mobile terminal also has a file H1 with a timestamp equal to Th and a file name Fh1, the file H1 is a continuous shooting file of the file H, and the mobile terminal synchronizes the file H1 to the display device.

In some embodiments, the display device will not begin recording or updating the minimum time point, the maximum time point, the minimum time point corresponding file name, and the maximum time point corresponding file name until each file is received successfully. When the mobile terminal synchronizes the file to the display device, the mobile terminal carries request information, wherein the request information comprises a file name, file generation time and a file synchronization direction (the direction of the current mobile terminal advancing to the display device to synchronize the file is marked to be in a direction with larger time or in a direction with smaller time). The display device records or updates the minimum time point, the maximum time point, the minimum time point corresponding file name, and the maximum time point corresponding file name according to the request information.

When the mobile terminal does not synchronize files with the display device, the records of the minimum time point and the maximum time point in the display device are zero. When the synchronization file is started, the minimum time point and the maximum time point are updated to non-zero values. Specifically, according to the above embodiment, the mobile terminal synchronizes the file to the display device for the first time, starting from the file with the largest time stamp and gradually decreasing the time stamp, when the mobile terminal synchronizes the first file TK to the display device, the maximum time point and the minimum time point are both actually TK, and the names of the files corresponding to the maximum time point and the minimum time point are both Fk.

In some embodiments, when the mobile terminal synchronizes the second file to the display device, if the timestamp of the second file is Tj, not equal to Tk, the second file and the first file are not continuous shooting files. After the display device is directly synchronized, the display device records Tk as a maximum time point, fk as a name of a file corresponding to the maximum time point, tj as a minimum time point, and Fj as a name of a file corresponding to the minimum time point. If the file synchronization is interrupted at this time, and the file is synchronized again and continuously, the maximum time point and the maximum time point are obtained to synchronize the file according to the mode of the embodiment.

In some embodiments, when the mobile terminal synchronizes the second file to the display device, if the timestamp of the second file is equal to the timestamp of the first file and the file names are different, it is necessary to acquire from the mobile terminal whether the current file synchronization direction is a direction in which the timestamp gradually increases or a direction in which the timestamp gradually decreases (mobile terminal automatic configuration). In this embodiment, the current file synchronization direction is a direction in which the time stamp gradually decreases. Therefore, after the synchronization file is successful, the file name of the file corresponding to the maximum time point is updated to be the name of the second file. When the next file is synchronized, the file needs to be judged to be continuously shot, and the name of the next file is directly compared with the name of the second file.

In some embodiments, when the mobile terminal synchronizes the second file to the display device, if the timestamp of the second file is greater than Tk, the second file is the newly added file. After the second file is successfully synchronized, the timestamp of the second file is recorded as the maximum time point, and the name of the second file is updated as the name of the file corresponding to the maximum time point.

In some embodiments, after the mobile terminal obtains the maximum time point and the minimum time point from the display device, when the timestamp of the third file synchronized by the mobile terminal to the display device is smaller than the minimum time point, after the synchronization is successful, the minimum time point is updated to be the timestamp of the third file, and the name of the file corresponding to the minimum time point is updated to be the name of the third file.

An embodiment of the present application provides a file synchronization method, such as a signaling diagram of the file synchronization method shown in fig. 10, where the method includes the following steps: the mobile terminal acquires the time stamp of the synchronized file on the time axis from the file receiving server, synchronizes the unsynchronized file with the time stamp of the synchronized file to the display device, and simultaneously updates the time stamp information on the time axis after the unsynchronized file is successfully received by the file receiving server, and simultaneously saves the received file to the hard disk.

In some embodiments, when the mobile terminal synchronizes the file to the display device for the first time, the mobile terminal does not have a time stamp on the time axis, and the mobile terminal cannot acquire the time stamp from the file receiving server, and then synchronizes all the files to the display device. The mobile terminal synchronizes the file from the file with the largest time stamp to the display device in the direction that the time stamp gradually decreases, and simultaneously records the largest time stamp of the last synchronization as the largest time point on the time axis and the smallest time stamp as the smallest time point on the time axis. Thus, when the process of synchronizing the files is interrupted due to network abnormality and the like, the files with the time stamp smaller than the minimum time point are all original old files, and the files with the time stamp larger than the maximum time point are all newly added files in next synchronization. The time stamps are synchronized files between the maximum time point and the minimum time point.

In some embodiments, in another file synchronization process after the synchronization interrupt according to the above embodiment, files with different time stamps on the time axis from the synchronized file time stamps are first searched, and these files are unsynchronized files. When the time stamp of the unsynchronized file is smaller than the minimum time point, the unsynchronized files are all original old files. The mobile terminal synchronizes the file to the display device in a direction in which the time stamp gradually decreases from the unsynchronized file with the largest time stamp, and simultaneously updates the time stamp of the unsynchronized file with the smallest time stamp to the smallest time point on the time axis. Thus, when the synchronization process is interrupted again and the file is synchronized again, the file with the time stamp which is not synchronized at this time and is smaller than the minimum time point is still the original old file. The original old files are synchronized in the mode, so that omission can be avoided, and repeated synchronization of the files can be avoided.

In some embodiments, when the time stamps of the unsynchronized files are all greater than the maximum time point, the mobile terminal judges that the unsynchronized files are newly added files, the unsynchronized files are synchronized to the display device from the file with the smallest time stamp in the newly added files in the direction that the time stamp is gradually increased, and meanwhile, the time stamp of the unsynchronized file with the largest time stamp is updated to the maximum time point. Thus, when the synchronization process is interrupted again and the file is synchronized again, the file with the time stamp which is not synchronized at this time and is larger than the maximum time point is still the newly added file. The newly added file is synchronized in the mode, so that omission can be avoided, and repeated synchronization of the file can be avoided.

In some embodiments, the mobile terminal may also obtain file names from the display device, if there are files in the mobile terminal that have the same time stamp as the files already synchronized to the display device, but have different file names, i.e., continuous shooting files, then synchronize these continuous shooting files to the display device, while the display device records the file names of the continuous shooting files while the display device saves the continuous shooting file data.
