when the file list comprises a mapping relation between the file identification and a first address corresponding to the file identification, the second processor sends the first address to the mobile terminal, wherein the file identification in the file list is an identification of a file uploaded to the cloud device by the server, and the first address is used for enabling the mobile terminal to obtain the file from the cloud device;

when the file list does not comprise the mapping relation between the file identification and the first address corresponding to the file identification, the second processor sends the file to cloud equipment, sends the response of the cloud equipment and a second address fed back after the file is received to the mobile terminal, establishes mapping between the second address and the file identification of the file, and updates the file list according to the newly established mapping, wherein the second address is used for enabling the mobile terminal to obtain the file from the cloud equipment.

9. A display device, comprising: a display, a network attached memory, and a processor, wherein,

the display is used for displaying a user interface;

the network attached storage is used for storing files;

the processor is configured to perform:

receiving a downloading request sent by a server;

determining a file corresponding to the downloading request;

when the size of the file is smaller than a first threshold value, uploading the file to a server so that the server forwards the file to a mobile terminal;

when the size of the file is larger than or equal to the first threshold value, the file is uploaded to the server, so that the server can receive the file, whether a mapping relation between a file identifier corresponding to the file and a first address corresponding to the file identifier is included in a pre-stored file list or not is judged, if yes, a corresponding download address is sent to the mobile terminal, the download address is used for enabling the mobile terminal to download the file, if not, the file is sent to a cloud device, a second address fed back after the cloud device responds and receives the file is sent to the mobile terminal, mapping between the second address and the file identifier of the file is established, and the file list is updated according to the newly established mapping, wherein the second address is used for enabling the mobile terminal to obtain the file from the cloud device.

10. The display device according to claim 9,

when the size of the file is smaller than a first threshold value, uploading the file to a server, so that the server forwards the file to the mobile terminal comprises:

when the size of the file is smaller than a first threshold value, uploading the file to a message forwarding server so that the message forwarding server forwards the file to the mobile terminal;

when the size of the file is larger than or equal to the first threshold, uploading the file to the server, so that the server sends a corresponding download address to the mobile terminal after receiving the file, wherein the file download method comprises the following steps:

when the size of the file is larger than or equal to the first threshold value, uploading the file to a file management server;

receiving a download address fed back by the file management server;

and sending the download address to the mobile terminal through the message forwarding server.

11. A data transmission method is applied to a server, and the method comprises the following steps:

receiving the file uploaded by the display equipment;

when a pre-stored file list comprises a mapping relation between a file identifier corresponding to a file and a first address corresponding to the file identifier, sending the first address to the mobile terminal, wherein the file identifier in the file list is an identifier of the file uploaded by the server to a cloud device, and the first address is used for enabling the mobile terminal to obtain the file from the cloud device;

when the file list does not include the mapping relation between the file identification and the first address corresponding to the file identification, the file is sent to a cloud device, a second address fed back after the cloud device responds and receives the file is sent to the mobile terminal, mapping is established between the second address and the file identification of the file, and the file list is updated according to the newly established mapping, wherein the second address is used for enabling the mobile terminal to obtain the file from the cloud device.

12. A data transmission method is applied to a server, wherein a first processor and a second processor are arranged in the server, and the method comprises the following steps:

the first processor sends the download request to the display device to enable the display device to upload the file;

when the size of the file is larger than or equal to the first threshold value, the second processor receives the file uploaded by the display device, judges whether a mapping relation between a file identifier corresponding to the file and a first address corresponding to the file identifier is included in a pre-stored file list, if so, sends a corresponding download address to the mobile terminal, wherein the download address is used for enabling the mobile terminal to download the file, if not, the file is sent to a cloud device, sends a second address fed back after the cloud device responds and receives the file to the mobile terminal, establishes mapping between the second address and the file identifier of the file, and updates the file list according to the newly established mapping, wherein the second address is used for enabling the mobile terminal to obtain the file from the cloud device.

13. A data transmission method, applied to a display device, the method comprising:

receiving a downloading request sent by a message forwarding server;

determining a file corresponding to the downloading request;

when the size of the file is larger than or equal to the first threshold value, uploading the file to the server, so that the server receives the file, judging whether a mapping relation between a file identifier corresponding to the file and a first address corresponding to the file identifier is included in a pre-stored file list, if so, sending the download address to the mobile terminal, if not, sending the file to cloud equipment, sending a second address fed back after the cloud equipment responds and receives the file to the mobile terminal, mapping the second address and the file identifier of the file, and updating the file list according to the newly established mapping, wherein the second address is used for enabling the mobile terminal to obtain the file from the cloud equipment.
