Referring to fig. 1, fig. 1 is a flow chart of a file downloading method according to an embodiment of the present application.
As shown in fig. 1, the file downloading method includes steps S101 to S105.
Step S101, acquiring a downloading site set of a target file, and determining network communication quality between each intelligent device in at least two intelligent devices and each downloading site in the downloading site set.
When the network file needs to be downloaded, a user can send a downloading instruction through an operation page or a menu bar, a server receives the downloading instruction, crawls the network IP address of the network file on the Internet according to the downloading instruction, and then sends the network IP address of the crawled network file to the main control equipment, so that a downloading site set of the file is obtained. The master control device is used for receiving the downloading site set sent by the server, or receiving each downloading site sent by the server in preset time, and generating the downloading site set on the master control device. The preset time can be set according to specific conditions, and the application is not particularly limited.
For example, when a user wants to download a movie, an instruction to download the movie can be issued to the television through a television operation interface or a remote controller, and the instruction is sent to the server. Based on the instruction, the server crawls the IP addresses capable of downloading the movie through the Internet, the IP addresses are usually a plurality of, and then the crawled IP addresses capable of downloading the movie are sent to the main control equipment, so that a downloading site set of the movie can be obtained.
In an embodiment, the method for acquiring the downloading site set of the target file specifically includes: searching the keywords of the target file through a network search engine to obtain a plurality of websites storing the keywords of the target file; screening a plurality of websites storing keywords of the target files, and reserving websites storing downloading paths of the target files to obtain downloading websites of the plurality of target files; through the download websites of the plurality of target files, the download links of the plurality of target files can be obtained; and sending the download links of the plurality of target files to the main control equipment, so as to obtain a download site set of the target files. The target file is a file to be downloaded.
Further, after the master control device completes receiving the download site set of the target file, each download site in the download site set is verified, and the download sites with inconsistent formats and contents of the target file in the download sites are eliminated. The specific method for verifying each download site in the download site set is as follows: acquiring the format and the size of a target file in each downloading site, and determining the number of downloading sites with the same format and size of the target file; and reserving the downloading sites with the same format and size of the target file, and deleting the downloading sites with different formats and/or sizes of the target file to update the downloading site set. The format of the target file is not particularly limited, and the target files downloaded through different downloading sites can be compatible. By verifying each download site in the download site set, the consistency of the downloaded target file is ensured.
In one embodiment, the method for acquiring the downloading site set of the target file includes: the user sends a target file downloading request through a button or a control, the server acquires the target file downloading request, crawls the downloading address of the target file on the Internet according to the format and the size of the target file carried in the target file downloading request, and then sends the crawled downloading address to the main control equipment, so that a downloading site set of the target file is obtained. It should be noted that, a preset size difference may exist between the file size in the obtained download address and the size of the target file, and the preset size difference may be defined according to a specific situation, for example, when the size of the target file is 1G, the preset size difference may be 1M.
After the download site set of the target file is acquired, network communication quality between each of the at least two intelligent devices and each of the download sites in the download site set is determined. It should be noted that, the network communication quality includes, but is not limited to, network bandwidth, time delay, jitter, load, etc., and the network bandwidth, time delay, jitter, load, etc. of the network communication quality are counted by the master control device, and the counted result is stored in a local file form, where the intelligent device may be an electronic device such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, a television, etc., or may be an intelligent household appliance such as an intelligent refrigerator, an intelligent air conditioner, an intelligent washing machine, etc. According to the network communication quality between each intelligent device and each downloading site in the downloading site set, each intelligent device can select the optimal downloading site to download the target file, and the speed of downloading the target file is improved.
The main control equipment is provided with a signaling management module which is used for monitoring information interaction between each intelligent equipment and each downloading site. The signaling management module comprises a signaling management unit, wherein the signaling management unit is used for maintaining information in the interaction process between each intelligent device and each downloading site. In the standard P2P protocol, each node performs periodic information interaction, and network bandwidth, time delay, jitter, load and the like between each intelligent device and each download site can be detected through real-time information interaction. It should be noted that, the master control device may also count network bandwidth, delay, jitter, load, etc. between each intelligent device and each download site at regular time.
Step S102, determining the downloading site corresponding to each intelligent device according to the network communication quality between each intelligent device and each downloading site and the downloading site set.
And selecting the downloading sites from the downloading site set to be distributed to each intelligent device according to the downloading site set of the target file acquired by the main control device and the network communication quality between each intelligent device and each downloading site, so that each intelligent device is distributed to the corresponding downloading site. By distributing the corresponding downloading sites for each intelligent device, network congestion caused by downloading the target file in one downloading site by a plurality of intelligent devices is avoided, and the speed of downloading the target file by each intelligent device at the same time is improved.
It should be noted that, according to the quality of the network communication between each intelligent device and each download site, a download site with better network communication quality may be allocated to each intelligent device, and each intelligent device downloads the target file through the download site. The quality of the network communication quality can be judged through preset network communication quality conditions, the preset network communication quality conditions can be set according to specific situations, the application is not particularly limited herein, and optionally, the preset network communication quality conditions are set to be that the network bandwidth is larger than 1M/S and the time delay is smaller than 100ms.
Further, under the condition that the number of the downloading sites in the downloading site set is large, a main downloading site and one or more backup downloading sites can be distributed to each intelligent device, and when the downloading rate of the corresponding main downloading site is lower than a preset rate, each intelligent device can be switched to the backup downloading site to download, so that each intelligent device can finish own downloading task.
In an embodiment, the determining manner of the download site corresponding to each intelligent device specifically includes: ordering the network communication quality between each intelligent device and each download site to generate a network communication quality list of each intelligent device; determining the priority of each intelligent device according to the arrangement sequence of each intelligent device in the network communication quality list; and determining the downloading site corresponding to each intelligent device from the downloading site set according to the priority of each intelligent device, wherein the intelligent devices are uniquely corresponding to the downloading sites, so that each intelligent device selects different downloading sites in the same time period.
It should be noted that, the network communication quality between each intelligent device and each download site may be ordered, or the network bandwidth or time delay between each intelligent device and each download site may be ordered according to at least two combinations of the network bandwidth, time delay, load and jitter between each intelligent device and each download site, which is not limited in this application. According to the arrangement sequence of each intelligent device in the network communication quality list, determining the corresponding priority label for each intelligent device, and according to the corresponding priority label of each intelligent device, determining the priority of each intelligent device, wherein the intelligent device with the front arrangement sequence has high priority. According to the priority of each intelligent device, firstly selecting a corresponding downloading site for the intelligent device with high priority, and then selecting a corresponding downloading site for the intelligent device with low priority, wherein each intelligent device selects different downloading sites in the same time period. Illustratively, when the higher priority smart device a selects the download site 1, the smart device B having a lower priority than the smart device a cannot select the download site 1, but can select the download site which is not selected by the smart device temporarily even though the network communication quality with the download site 1 is good.
Step S103, determining the number of file blocks corresponding to each intelligent device according to the network communication quality between each intelligent device and the corresponding downloading site.
After determining the download site corresponding to each intelligent device, the number of file blocks to be downloaded by each intelligent device at the download site corresponding to each intelligent device needs to be determined. Specifically, according to the network communication quality between each intelligent device and the corresponding download site, determining the number of the file blocks corresponding to each intelligent device, wherein the better the network communication quality between each intelligent device and the corresponding download site is, the more the number of the file blocks required to be downloaded by each intelligent device at the corresponding download site is, otherwise, the worse the network communication quality between each intelligent device and the corresponding download site is, and the fewer the number of the file blocks required to be downloaded by each intelligent device at the corresponding download site is. The number of the file blocks corresponding to each intelligent device is determined according to the network communication quality between each intelligent device and the corresponding downloading site, so that the downloading time required by downloading the file blocks corresponding to each intelligent device is consistent, and the problem that the target file cannot be downloaded in time due to overlong time of downloading the file blocks of a certain intelligent device is avoided.
After each intelligent device determines the corresponding downloading site, the server blocks the target file in each downloading site. Specifically, the master control device includes a file block splitting module, where the file block splitting module is configured to calculate, according to a size of a target file to be downloaded, a number N of splitting the target file into file blocks, and send a splitting request to the server, where the splitting request requests splitting of the file to be downloaded into N file blocks. It can be understood that the size of the split file block is fixed, and the server can split the target file in each download site according to the size of the file block in the split request sent by the master control device.
In an embodiment, the network communication quality includes a network bandwidth, and the specific method for determining the number of file blocks corresponding to each intelligent device includes: acquiring the total number of file blocks of a target file, and accumulating the network bandwidth between each intelligent device and the corresponding downloading site to obtain the total network bandwidth; calculating the proportion of the network bandwidth between each intelligent device and the corresponding download site to the total network bandwidth; and determining the number of the file blocks corresponding to each intelligent device according to the total number of the file blocks and the proportion of the network bandwidth between each intelligent device and the corresponding downloading site to the total network bandwidth.
It should be noted that, the master control device multiplies the total number of file blocks by the ratio of the network bandwidth between each intelligent device and the corresponding download site to the total network bandwidth to obtain the number of file blocks corresponding to each intelligent device, so that it can be known that the larger the network bandwidth between each intelligent device and the corresponding download site is, the higher the ratio of the total network bandwidth is, and the more the number of file blocks corresponding to each intelligent device is. By the distribution mode of the downloaded file blocks, the number of the file blocks of the corresponding downloaded target file of each intelligent device is more reasonable.
And step S104, controlling each intelligent device to download the file blocks of the target file according to the number of the file blocks and the download sites corresponding to each intelligent device.
After determining the number of the file blocks and the downloading sites corresponding to each intelligent device, the master control device controls each intelligent device to download the file blocks of the target file. Specifically, each file block of the target file has a corresponding identifier, the identifier uniquely corresponds to the file block, and the file block can be accurately found through the identifier. Before downloading the file blocks, the main control equipment sends identifiers of the file blocks corresponding to the number of the file blocks to each intelligent equipment, and each intelligent equipment downloads the file blocks of the target file in a downloading site according to the identifiers of the corresponding file blocks.
For example, the number of file blocks corresponding to the intelligent device a is 100, the download site corresponding to the intelligent device a is "http:// download.1717.com/", the total number of file blocks is 500, the number of identifiers is 500, the master control device may send the identifiers in the interval 201 to 300 to the intelligent device a, and the intelligent device a corresponds to the file blocks of the download target file on the download site "http:// download.1717.com/", according to the 100 identifiers in the interval.
In an embodiment, according to the number of file blocks and the downloading sites corresponding to each intelligent device, generating a file downloading task corresponding to each intelligent device; and controlling each intelligent device to download the file block of the target file from the corresponding download site according to the file download task corresponding to each intelligent device. The file downloading task comprises the number of file blocks and downloading sites corresponding to each intelligent device, the downloading progress and the downloading rate of each intelligent device can be displayed through the file downloading task, and a user can execute operations such as pause downloading, re-downloading and the like on a file downloading task interface.
And step 105, executing file block reorganization operation according to the file blocks obtained by downloading each intelligent device, and generating the target file.
And when the file blocks of the target file are downloaded by each intelligent device, the central control device executes file block reorganization operation so as to generate the target file in the central control device. It should be noted that, after the central control device completes the reorganization operation on the file block of the target file, the target file may also be sent to any memory for storage.
In an embodiment, the target file is segmented into file blocks with unique corresponding identifiers in the download website, when the central control device executes file block reorganization operation, each file block is corresponding to the corresponding unique identifier, when the unique identifier of the file block exists, the file block is skipped and not processed, and when the unique identifier of the file block does not exist, the file block is re-downloaded and filled into the reorganized target file through the intelligent device.
According to the file downloading method provided by the embodiment, through the obtained downloading site set of the target file and the determined network communication quality between each intelligent device and each downloading site, the respective corresponding downloading site and the respective number of file blocks of each intelligent device can be obtained, then the file blocks of the target file are downloaded by each intelligent device are controlled according to the respective corresponding number of the file blocks and the respective downloading sites of each intelligent device, and file block reorganization operation is carried out on the file blocks obtained by downloading, so that the target file is generated. Network congestion caused by the fact that a plurality of intelligent devices simultaneously download target files in one downloading site is avoided, meanwhile, file blocks of the target files are reasonably distributed to each intelligent device, and the speed of downloading the files is effectively improved.
Referring to fig. 2, fig. 2 is a flowchart of another file downloading method according to an embodiment of the present application.
As shown in fig. 2, the file downloading method includes steps S201 to S208.
Step S201, obtaining a downloading site set of the target file, and determining network communication quality between each intelligent device in at least two intelligent devices and each downloading site in the downloading site set.
After the download site set of the target file is acquired, network communication quality between each of the at least two intelligent devices and each of the download sites in the download site set is determined. The target file is a file to be downloaded, and it should be noted that the network communication quality includes, but is not limited to, network bandwidth, delay, jitter, load, and the like.
Step S202, determining the downloading site corresponding to each intelligent device according to the network communication quality between each intelligent device and each downloading site and the downloading site set.
And selecting the downloading sites from the downloading site set to be distributed to each intelligent device according to the downloading site set of the target file acquired by the main control device and the network communication quality between each intelligent device and each downloading site, so that each intelligent device is distributed to the corresponding downloading site. By distributing the corresponding downloading sites for each intelligent device, network congestion caused by downloading the target file in one downloading site by a plurality of intelligent devices is avoided, and the speed of downloading the target file is improved.
Step S203, determining the number of file blocks corresponding to each intelligent device according to the network communication quality between each intelligent device and the corresponding download site.
After determining the download site corresponding to each intelligent device, the number of file blocks to be downloaded by each intelligent device at the download site corresponding to each intelligent device needs to be determined. Specifically, according to the network communication quality between each intelligent device and the corresponding download site, determining the number of file blocks corresponding to each intelligent device, wherein the number of file blocks is the number of file blocks obtained by splitting the target file into the file blocks by the main control device according to the size of the target file to be downloaded.
And step S204, controlling each intelligent device to download the file blocks of the target file according to the number of the file blocks and the download sites corresponding to each intelligent device.
After determining the number of the file blocks and the downloading sites corresponding to each intelligent device, the master control device controls each intelligent device to download the file blocks of the target file. Specifically, each file block of the target file has a corresponding identifier, the identifier uniquely corresponds to the file block, and the file block can be accurately found through the identifier.
Step S205, when at least one intelligent device is detected to be in an idle state, acquiring an identifier set of a file block which is not downloaded and the current network communication quality between each intelligent device and a corresponding downloading site.
By detecting the network communication quality of the intelligent devices, judging whether the intelligent devices are in an idle state according to the network communication quality of the intelligent devices, when at least one intelligent device is detected to be in the idle state, acquiring an identifier set of a file block which is not downloaded by other intelligent devices, and acquiring the current network communication quality between each intelligent device and a corresponding downloading site. The central control device can send the identifier in the identifier set to the intelligent device which completes the downloading task so as to download the corresponding file blocks through the intelligent device which completes the downloading task.
Whether the intelligent device is in an idle state is judged by determining whether the network communication quality of the intelligent device reaches a preset communication quality threshold, and the preset communication quality threshold can be set according to specific conditions, so that the application is not limited in particular.
Step S206, determining the respective identifier subset of each intelligent device according to the identifier set and the current network communication quality between each intelligent device and the respective download site.
And determining the respective identifier subset of each intelligent device according to the identifier set and the current network communication quality between each intelligent device and the respective corresponding downloading site. Specifically, determining the number of identifiers corresponding to each intelligent device according to the identifier set and the current network communication quality between each intelligent device and the corresponding download site; and determining the identifier subset corresponding to each intelligent device according to the identifier number and the identifier set corresponding to each intelligent device.
It should be noted that the identifier set includes a plurality of identifier subsets, each identifier subset includes a plurality of identifiers, each file block of the target file has a corresponding identifier, and the identifier uniquely corresponds to the file block; when the current network communication quality between each intelligent device and the corresponding download site is high, the number of identifiers corresponding to each intelligent device is large, and the subset of identifiers corresponding to each intelligent device is large; when the current network communication quality between each intelligent device and the corresponding download site is low, the number of identifiers corresponding to each intelligent device is small, and the subset of identifiers corresponding to each intelligent device is small.
The method for determining the number of the identifiers corresponding to each intelligent device specifically comprises the following steps: and acquiring a preset mapping relation table of the current network communication quality and the number of identifiers, and determining the number of the identifiers corresponding to each intelligent device according to the mapping relation table and the current network communication quality between each intelligent device and the corresponding downloading site. The preset mapping relation table of the current network communication quality and the number of identifiers can be set according to specific situations, and optionally, the mapping relation table comprises a plurality of grades, the current network communication quality is in different grades, and the number of the identifiers corresponding to the current network communication quality is different.
And S207, controlling each intelligent device to download the file block of the target file according to the identifier subset and the downloading site corresponding to each intelligent device.
After determining the identifier subset corresponding to each intelligent device, controlling the intelligent device to download the file block of the target file according to the identifier subset corresponding to each intelligent device and the downloading site.

By redefining the download site corresponding to the intelligent device, the influence on the speed of downloading the target file by the intelligent device can be eliminated in the special case when the network communication quality between the intelligent device and the download site is interrupted or regarded as interrupted.
And step S208, executing file block reorganization operation according to the file blocks obtained by downloading each intelligent device, and generating the target file.
And when the file blocks of the target file are downloaded by each intelligent device, the central control device executes file block reorganization operation so as to generate the target file in the central control device. It should be noted that, after the central control device completes the reorganization operation on the file block of the target file, the target file may also be sent to any memory for storage.
