Abstract

The embodiments of the present application disclose a data processing method and system based on cloud storage. The method includes: a cloud management device receiving a data query request sent by a client via a cloud work device, wherein the data query request is used to request for querying media data that has been stored in a cloud domain, the cloud work device is a default storage cloud domain of an IP camera; the cloud management device querying whether the media data collected by the IP camera is stored in a cloud backup device according to the data query request; and if the cloud management device determines that the media data of the IP camera is stored in the cloud backup device according to the data query request, pushing an address of the media data to the cloud work device, wherein the address of the media data is used for the client to request for querying the media data from the cloud backup device. The present application solves the technical problem of poor data storage flexibility among cloud domains in related arts.

First claim

What is claimed is:

1. A data processing method based on cloud storage, comprising:
a cloud management device receiving a data query request sent by a client via a cloud work device, wherein the data query request is used to request for querying media data that has been stored in a cloud domain, the cloud work device is a default storage cloud domain of an IP (Internet Protocol) camera;
the cloud management device querying whether media data collected by the IP camera is stored in a cloud backup device according to the data query request; and
if the cloud management device determines that the media data of the IP camera is stored in the cloud backup device according to the data query request, pushing an address of the media data to the cloud work device, wherein the address of the media data is used for the client to request for querying the media data from the cloud backup device;
wherein the media data comprises video data, and the data query request comprises a first time period, the cloud management device querying whether media data collected by the IP camera is stored in a cloud backup device according to the data query request comprises:
the cloud management device querying a storage trajectory of the IP camera in the first time period according to the data query request, wherein the storage trajectory records information on a cloud domain in which the video data is stored in each time period, and the cloud domain comprises the cloud work device and the cloud backup device;
the cloud management device determining whether the storage trajectory records information on the cloud backup device; and
if it is determined that the storage trajectory records the information on the cloud backup device, determining that the video data collected by the IP camera is stored in the cloud backup device.

2. The method according to claim 1 , wherein pushing the address of the media data to the cloud work device comprises:
the cloud management device pushing the address of the media data to the cloud work device and pushing a time period associated with the video data stored in the cloud backup device to the cloud work device.

3. The method according to claim 1 , wherein the media data comprises video data, and after pushing the address of the media data to the cloud work device, the method further comprises:
the client, according to the address of the media data, requesting for video data stored during a first preset time period from the cloud backup device; and
the client receiving first video data returned by the cloud work device, wherein the first video data is video data stored in the cloud backup device during the first preset time period.

4. The method according to claim 3 , wherein the method further comprises:
determining, according to the storage trajectory of the IP camera, whether information on a data forwarding server in the cloud management device needs to be acquired when the cloud work device receives a request for acquiring the information on the data forwarding server sent by the client;
if the cloud work device determines that the information on the data forwarding server in the cloud management device needs to be acquired, sending the information on the data forwarding server in the cloud management device to the client; and
if the cloud work device determines that the information on the data forwarding server in the cloud management device does not need to be acquired, sending information on a data forwarding server in the cloud work device to the client.

5. The method according to claim 1 , wherein before the client sends a data query request via the cloud work device, the method further comprises:
the cloud management device caching user information when the user information in the cloud work device is acquired; and
when the user information in the cloud work device is changed, the cloud management device acquiring the user information that is changed in the cloud work device according to a received user information change request and updating the user information that has been cached, wherein the user information change request is generated by the cloud work device according to a user right configuration of the client.

6. The method according to claim 1 , wherein the method further comprises
the cloud management device instructing the cloud backup device to perform user binding when receiving a user binding request sent by the client; and
the cloud management device instructing the cloud backup device to synchronize the user information when receiving a user information synchronization request sent by the client.

7. The method according to claim 3 , wherein the method further comprises:
the cloud management device determining whether a fault occurs in the cloud work device;
if the cloud management device determines that a fault occurs in the cloud work device, instructing the IP camera to store the media data in the cloud backup device.

8. A data processing method based on cloud storage, comprising:
an IP camera sending media data collected by the IP camera to a cloud work device;
the IP camera receiving a first instruction sent by a cloud management device, wherein the first instruction is used to instruct the IP camera to store the media data collected by the IP camera in a cloud backup device; and
the IP camera storing the media data collected by the IP camera in the cloud backup device according to the first instruction;
wherein the media data comprises picture data, and the IP camera sending the media data collected by the IP camera to the cloud work device comprises:
the IP camera requesting for first gateway information of the cloud work device from the cloud work device;
after receiving the first gateway information of the cloud work device, the IP camera sending the picture data to a first gateway associated with the first gateway information;
the IP camera receiving a first response sent by the first gateway, wherein the first response is used to indicate that the first gateway determines that storage resource of the cloud work device is sufficient to store the picture data; and
the IP camera sending the picture data to the work cloud device via the first gateway.

9. The method according to claim 8 , wherein the IP camera storing the media data collected by the IP camera in the cloud backup device according to the first instruction comprises:
the IP camera acquiring an address of the media data in the first instruction; and
the IP camera storing the media data in the cloud backup device according to the address.

10. The method according to claim 9 , wherein after the IP camera stores the media data collected by the IP camera in the cloud backup device according to the first instruction, the method further comprises:
the IP camera receiving a second instruction sent by the cloud management device, wherein the second instruction is used to instruct the IP camera to store the media data collected by the IP camera to the cloud work device; and
the IP camera storing the media data collected by the IP camera in the cloud work device according to the second instruction.

11. An electronic device, wherein the electronic device comprises a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other via the communication bus;
the memory is configured to store a computer program;
