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

In order to solve the above problem, an embodiment of the present application provides a file synchronization system, as shown in a schematic diagram of a file synchronization system framework shown in fig. 6, the file synchronization system includes a mobile terminal 300A and a display device 200, a file in the mobile terminal is transmitted to a NAS hard disk through a network, and the file synchronization system shown in fig. 6 may transmit file data based on a wide area network or may 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 both the file receiving server and the NAS hard disk may be integrated inside the display device, or may be used as an external device connected to the display device.

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

In the embodiment of the application, the mobile terminal needs to establish connection with the display device, and after the mobile terminal establishes communication with the display device, 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 the display equipment authorizes the mobile terminal to perform the action of synchronizing the file to the display equipment according to the actual situation after receiving the request. Each display device can authorize a plurality of mobile terminals at the same time, and each mobile terminal can also 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 every time the display device is found to be in sequence.

Illustratively, 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 about the home private cloud application is scanned by using a scanning function of the 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, a home private cloud application applet is opened on the mobile terminal, such as the haohwayor applet application interface shown in fig. 8. The user may select all files to be synchronized to the display device through the masquerade applet application interface. According to the embodiment of the application, after the display device authorizes the mobile terminal, the mobile terminal automatically synchronizes the file to the display device.

The file receiving server in the embodiment of the present application maintains a time axis of a synchronization file for each mobile terminal device, for example, as shown in fig. 9, time stamps of files are all time generated for the files by the mobile terminal of the file itself, and for example, the shooting time may be taken as the time stamp of the file, or the time shared by other devices may be taken as the time stamp of the file, so that each file has a unique time stamp (here, the special case of continuous shooting of the file is not considered), and each file can be uniquely marked 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 to the display device. The mobile terminal can obtain the time stamp of the file synchronized to the display device from the display device, and only synchronizes unsynchronized files to the display device according to the time stamp, namely, the time stamp synchronized to the display device is not equal to the time stamp of the file synchronized to the display device by the mobile terminal. The file receiving server can only receive the unsynchronized file. Therefore, the synchronized files do not need to be repeatedly synchronized, the resource waste is avoided, and the synchronization efficiency is improved.

Illustratively, as shown in fig. 9, the mobile terminal stores files a to H8, and files D to H are files synchronized to the display device, the time axis maintained by the file server is marked with a file D to H file timestamp Td to a timestamp Th, and it is determined from the timestamps that the mobile terminal does not need to synchronize the files D to H to the display device, but needs to synchronize unsynchronized files a to C without timestamps on the time axis.

In some embodiments, the mobile terminal has not synchronized the file to the display device, and the time axis maintained by the file server for the mobile terminal is not marked with any time stamp. All files stored in the mobile terminal are unsynchronized files. The mobile terminal can synchronize files directly to the display device without determining whether a timestamp already exists. Specifically, the files are synchronized to the display device in a direction in which the time stamps gradually decrease from the file having the largest time stamp. Therefore, if the synchronous file is interrupted due to the factors of the mobile terminal leaving the network range of the display equipment and the like in the process of synchronizing the file, the file which is not synchronized is classified as the original file when the file is synchronized again next time.

For example, as shown in fig. 9, the mobile terminal stores files a to H8, the 8 files are not 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 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 timestamp in the direction that the timestamp is gradually reduced. Thus, when the synchronization is interrupted, for example, at file C, the files synchronized to the display device are files D to H, and 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 to 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 maximum time point, and the timestamp with the smallest timestamp value in the unsynchronized file received by the display device is recorded as the minimum time point. Illustratively, if in synchronization, synchronization is interrupted at file C, files that have been synchronized to the display device are files D to H, where a timestamp Td of file D is a minimum timestamp, the timestamp Td is recorded as a minimum point in time, a timestamp Th of file H is a maximum timestamp, and Th is recorded as a maximum timestamp. Therefore, when the file is synchronized next time, the file of which the time stamp is greater than the minimum time point and is less than the maximum time point can be directly judged to be the file synchronized to the display device, and the mobile terminal does not need to synchronize the files to the display device.

In some embodiments, when the display device stores the file synchronized by the mobile terminal, the mobile terminal obtains the recorded maximum time point and the recorded minimum time point from the display device. And comparing the files stored in the mobile terminal with the maximum time point and the minimum time point, and if the unsynchronized files exist and the time stamps of the unsynchronized files are less than the minimum time point, synchronizing the unsynchronized files to the display device in the direction of gradually reducing the time stamps from the unsynchronized file with the maximum time stamp.

Illustratively, as shown in fig. 9, the time stamps of files D to H synchronized by the mobile terminal to the display device are Td to Th, the maximum time point acquired by the mobile terminal from the display device is Th, and the minimum time point is Td. And the mobile terminal synchronizes the files to the display device in the direction that the time stamps are gradually reduced from the file C with the largest time stamp in the unsynchronized files because the last synchronization is interrupted and the original files A to C are not synchronized to the display device and the time stamps of all the unsynchronized files are smaller than the minimum time point Td. If in this synchronization, the synchronization is interrupted at file A, file A is still of the original file's category. In the uploading process, the file B and the file C are successfully synchronized to 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 the time stamp Tb of the file B. And when the file synchronization process is carried out again, judging the files needing to be synchronized by the updated minimum time point Tb, namely synchronizing the original files A. The embodiment can solve the problem of file synchronization in the scene of synchronization interruption.

In some embodiments, when the display device stores the file synchronized by the mobile terminal, the mobile terminal obtains the recorded maximum time point and the recorded minimum time point from the display device. And comparing the files stored in the mobile terminal with the maximum time point and the minimum time point, and if the unsynchronized files exist and the time stamps of the unsynchronized files are greater than the maximum time point, synchronizing the unsynchronized files to the display device in the direction of gradually increasing the time stamps from the unsynchronized files with the minimum time stamps.

Illustratively, as shown in fig. 9, the time stamps of files D to H synchronized by the mobile terminal to the display device are Td to Th, the maximum time point acquired by the mobile terminal from the display device is Th, and the minimum time point is Td. In this embodiment, the mobile terminal stores a new file I to a new file K, and timestamps Ti to Tk of the new file I to the new file K, where the timestamps Ti to Tk are all greater than the maximum time point Th. And the mobile terminal synchronizes the files to the display device in the direction of gradually increasing the timestamp from the file I with the minimum timestamp in the unsynchronized files I to K. If the synchronization is interrupted at the file K during the process of synchronizing the files, the file K is still the category of the newly added file. In the uploading process, the file I and the file J are successfully synchronized to 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 carried out again, judging the file needing synchronization, namely the newly added file K, according to the updated maximum time point Tj. And if the newly added files are continuously stored in the mobile terminal in the synchronization, the newly added files are continuously synchronized in the mode. The embodiment can solve the problem of file synchronization in the scene that the mobile terminal stores the newly added file.

In some embodiments, when the display device stores the file synchronized by the mobile terminal, the mobile terminal obtains the recorded maximum time point and the recorded minimum time point from the display device. Comparing the files stored in the mobile terminal with the maximum time point and the minimum time point, if the unsynchronized files with the file time stamps larger than the maximum time point and the unsynchronized files with the file time stamps smaller than the minimum time point exist at the same time, firstly synchronizing the unsynchronized files with the time stamps larger than the maximum time point and then synchronizing the unsynchronized files with the time stamps smaller than the minimum time point, or firstly synchronizing the unsynchronized files with the time stamps smaller than the minimum time point and then synchronizing the unsynchronized files with the time stamps larger than the maximum time point. The specific embodiment refers to the process of synchronizing the original file and the new file in the uploading embodiment.

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

In some embodiments, the mobile terminal may store a file with the same timestamp, such as a continuous shooting file, where the continuous shooting file is a plurality of photos taken by the mobile terminal at the same time point. After the mobile terminal acquires the maximum time point and the minimum time point from the display device, if it is directly determined that the file with the timestamp greater than the minimum time point and less than the maximum time point is the file synchronized to the display device, the continuous shooting file with the timestamp equal to the minimum time point or equal to the maximum time point is missed. Therefore, in the present embodiment, when the file timestamp is equal to the minimum time point or equal to the minimum time point, it is further determined whether the file name is the same as the currently defined file corresponding to the maximum time point or the file corresponding to the maximum time point. If the difference is not the same, the continuous shooting file needs to be further synchronized.

Illustratively, files D-H are files in the mobile terminal that have been synchronized to the display device, file D has the name Fd, file H has the name Fh, and when there is also a file D1 with a timestamp equal to Td and the file name Fd1 in the mobile terminal, file D1 is a continuous shooting file of file D, and the mobile terminal synchronizes file D1 to the display device. Alternatively, 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 shot of the file H, and the mobile terminal synchronizes the file H1 to the display device.

In some embodiments, the display device will not start recording or updating the minimum time point, the maximum time point, the corresponding file name of the minimum time point and the corresponding file name of the maximum time point after receiving each file successfully. When synchronizing files 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 (for identifying whether the advancing direction of the current mobile terminal to the display device to synchronize the files is towards a direction with larger time or towards a direction with smaller time). And the display equipment records or updates the minimum time point, the maximum time point, the file name corresponding to the minimum time point and the file name corresponding to the maximum time point according to the request information.

When the mobile terminal does not synchronize the file to 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 first time the mobile terminal synchronizes the file to the display device is to start from the file with the largest timestamp and perform synchronization in the direction of gradually decreasing the timestamp, when the mobile terminal synchronizes the first file TK to the display device, both the maximum time point and the minimum time point are TK, and both the names of the files corresponding to the maximum time point and the minimum time point are 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 and is not equal to Tk, the second file and the first file are not burst files. After the file is directly synchronized to the display device, the display device records Tk as a maximum time point, records Fk as a name of a file corresponding to the maximum time point, records Tj as a minimum time point, and records 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 synchronization is continued again, the maximum time point and the maximum time point are obtained to synchronize the file according to the method of the above 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 not the same, it is required to acquire from the mobile terminal whether the current file synchronization direction is a direction in which the timestamp is gradually increased or a direction in which the timestamp is gradually decreased (mobile terminal auto-configuration). The current file synchronization direction in this embodiment is a direction in which the timestamp gradually decreases. Therefore, after the file is successfully synchronized, the name of the file corresponding to the maximum time point is updated to the name of the second file. When the next file is synchronized, the continuous shooting file needs to be judged, and the name of the continuous shooting 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 a newly added file. And after the second file is successfully synchronized, recording the timestamp of the second file as the maximum time point, and updating the name of the second file to the name of the file corresponding to the maximum time point.

In some embodiments, after the mobile terminal acquires the maximum time point and the minimum time point from the display device, and when a timestamp of a third file synchronized to the display device by the mobile terminal is smaller than the minimum time point, after the synchronization is successful, the minimum time point is updated to the timestamp of the third file, and the name of the file corresponding to the minimum time point is updated to 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 a time stamp of a synchronized file on a time axis from the file receiving server, synchronizes an unsynchronized file with the time stamp being unequal to that of the synchronized file to the display device, and the file receiving server updates time stamp information on the time axis simultaneously after receiving the unsynchronized file successfully and stores 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 timestamp does not exist on the time axis, and the mobile terminal cannot acquire the timestamp from the file receiving server, the mobile terminal synchronizes all the files to the display device. The mobile terminal synchronizes files to the display device in a direction in which the time stamps gradually decrease from the file with the largest time stamp, and simultaneously records the largest time stamp of the last synchronization as the maximum time point on the time axis and the smallest time stamp as the minimum time point on the time axis. Therefore, when the file synchronization process is interrupted due to network abnormality and the like, and the next time of synchronization, the files with the time stamps which are not synchronized at this time and are smaller than the minimum time point are all original old files, and the files with the time stamps which are larger than the maximum time point are all newly added files. The files with the time stamps between the maximum time point and the minimum time point are all synchronized files.

In some embodiments, in another file synchronization process after the synchronization interruption according to the foregoing embodiments, files with time stamps different from the time stamps of the synchronized files on the time axis are first searched, and the files are unsynchronized files. And when the time stamp of the unsynchronized files is less than the minimum time point, the unsynchronized files are all original old files. The mobile terminal synchronizes files to the display device in a direction in which the time stamp gradually decreases from the unsynchronized file having the largest time stamp, and at the same time updates the time stamp of the unsynchronized file having 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 unsynchronized timestamp less 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 timestamps of the unsynchronized files are all greater than the maximum time point, the mobile terminal judges the unsynchronized files as newly added files, synchronizes the unsynchronized files to the display device in the direction of gradually increasing the timestamps from the file with the smallest timestamp in the newly added files, and updates the timestamp of the unsynchronized file with the largest timestamp to the maximum time point. Thus, when the synchronization process is interrupted again and the file is synchronized again, the file with the unsynchronized timestamp larger than the maximum time point is still the newly added file. The newly added files are synchronized in the mode, so that omission can be avoided, and repeated synchronization of the files can be avoided.

In some embodiments, the mobile terminal may further acquire the file name from the display device, and if there is a file, i.e., a continuous shooting file, in the mobile terminal, whose timestamp is the same as that of the file already synchronized to the display device but whose file name is different, the continuous shooting file is synchronized to the display device, and the file name of the continuous shooting file is recorded while the display device saves the continuous shooting file data.
