Detailed Description

In order to more clearly illustrate the present invention, the present invention will be further described with reference to the following examples and the accompanying drawings. Similar components in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

In an interactive system based on the internet of things, remote devices often adopt a direct connection mode with a plurality of terminal devices, for example, as shown in fig. 1, Q terminal devices are all connected with the remote devices separately to form a transmission channel.

When the number of terminal devices downloading the file is small, the pressure of the remote device is small. When a plurality of terminal devices need to download files at the same time, the terminal devices with large number, cross-region, region relevance and different regions are all managed by one remote device, for example, in an information distribution scene, for example, the message sending display terminal devices in different cities are managed by a unified remote device.

In the above-mentioned distribution scenario, the network bandwidth of the terminal device is often used together with other services, for example, a plurality of distribution display terminal devices are configured in a branch point of a bank, each type of distribution display terminal device plays a consistent material, and different branch points are all connected to the same remote device. In the branch network, there are also terminal devices of other services, for example, terminal devices for managing the flow information, in the same network. Therefore, when a plurality of message display terminal devices of the branch network simultaneously request the remote device to download the file, a short-time network peak is caused, and other service systems are affected.

In actual construction, network bus resources from the remote device to the terminal device are often expensive and fixed, and network congestion is often caused when a large number of tasks are suddenly issued.

In view of the above, the present invention provides a file downloading method, a computer device and a storage medium to solve the above problems.

As shown in fig. 2, a first embodiment of the present invention provides a file downloading method, which is applied to a terminal device, and the method includes:

s21, each terminal device sends a working state and receives a download instruction which is generated by a remote device according to the working state and corresponds to each terminal device in the same group, and the terminal devices in the same group are communicated with each other and are connected with the remote device through the same network interface;

s23, each terminal device downloads split files forming the file according to the downloading instruction, wherein the split files downloaded by each terminal device are not overlapped, and all the split files are spliced to form a complete downloaded file;

and S25, according to the transmission instruction output by the remote equipment, different terminal equipment transmits the downloaded split file in the connection network of the group to obtain the complete downloaded file.

According to the technical scheme, the files downloaded by the terminal devices in the same group according to the downloading instructions are split files, after each terminal device finishes downloading the corresponding split file, the network interconnection characteristics of the same group are utilized, the split files are transmitted among the terminal devices, all the split files are spliced, each terminal device can finally download the complete downloaded file, the scheme can reduce the network pressure on the remote devices when multiple terminal devices download simultaneously, and the downloading efficiency is improved.

In one specific example, in the network environment shown in fig. 1, there are 5 terminal devices per branch network point. If the 5 terminal devices are in the same network and each terminal device is directly connected to a remote device and downloads a file to be published, and the file to be downloaded by each terminal device is a 100M file, the outlet flow rate required by ten terminal devices in the branch network to complete file downloading is 100M × 5, which is about 500M flow rate.

In the scheme of this embodiment, as shown in fig. 3, each branch node has 5 terminal devices. The 5 terminal devices are under the same network and are connected with the remote device through the same gateway interface. Each terminal device downloads a part of the whole file, for example, each terminal device downloads 20M split files, and after 5 split files of 20M are spliced, the whole downloaded file is obtained. The egress traffic required for 5 terminal devices to complete the download of the corresponding split file is 20M × 5, which is about 100M traffic.

Therefore, compared with the scheme of direct connection downloading, the scheme of the embodiment effectively reduces the network pressure on the remote equipment, avoids the short-time peak of the network and improves the network stability. And each terminal equipment only needs to download 20 files, and the terminal equipment in the same group has the interconnection characteristic of the same local area network, and the transmission speed can reach more than G, so that the split files of each terminal equipment can be transmitted and completed more quickly, the file downloading efficiency is effectively improved, and the success rate of file downloading is improved.

The file downloading method of the present embodiment is applied to the edge cloud interactive system as shown in fig. 4,

in an alternative embodiment, the interactive system comprises:

the management terminal is used for uploading files to the remote equipment, selecting the uploaded files, generating an issuing instruction to the remote equipment, and checking the states of the uploaded files in the remote equipment, such as an uploading state, a storage state, a downloading state or a distribution state.

And the remote equipment is used for scheduling the file to be issued and the terminal equipment to execute the downloading task according to the issuing instruction of the management terminal and outputting the downloading instruction.

And the terminal equipment is used for downloading the split files according to the downloading instruction and realizing mutual transmission of the split files in the same group. Illustratively, the terminal device performs the method illustrated in FIG. 2.

In a specific example, the interaction system of the embodiment is a side cloud interaction system, and illustratively, the remote device is a cloud terminal, and the terminal device is an edge terminal device. In another specific example, the remote device of the present embodiment is a server provided at a different location from the terminal. Illustratively, the interactive system of this embodiment can be applied to remote equipment to control a plurality of terminal devices, and a plurality of terminal devices can have a scene with regional relevance and a wide distribution range, for example, an internet of things operating system of a bank outlet, each display screen of a market, a smart park management platform or a station, and the like has a wide application prospect.

According to the interactive system, the remote equipment carries out downloading instruction and file splitting according to the working state of the terminal equipment, unified scheduling of the remote equipment is achieved, each terminal equipment in the same group downloads the split file according to the downloading instruction, and transmission of the split files among the terminal equipment is carried out by utilizing the network interconnection characteristics of the same group in the terminal equipment, so that the acquisition of the complete file is achieved.

The method performed by each end will now be described with specific embodiments.

For the management side, in an optional embodiment, as shown in fig. 5 and fig. 6, the method further includes:

and S61, uploading the file to the remote equipment, and acquiring the storage state fed back by the remote equipment.

For example, the present embodiment does not limit the type of the uploaded file, and details are not described herein again. Illustratively, the management terminal may upload the file to the remote device through actions such as clicking, screening, selecting, or dragging, and obtain a storage state of the uploaded file by the remote device, and illustratively, after the remote device completes storage of the file, a prompt may be generated and fed back to the management terminal.

S63, selecting files to be issued from the files stored in the remote equipment, and checking the issuing state of the download instruction output by the remote equipment.

In this embodiment, due to the diversity of the files stored in the remote device, the management terminal selects the files to be issued to each terminal device from the remote device, and generates an issuing instruction. After the remote equipment receives the issuing instruction, the remote equipment can generate a downloading instruction according to the file to be issued and the state of each terminal equipment, and unified scheduling is carried out. In a specific example, the management end can check the issuing state of the remote device at any time, that is, whether the remote device has started to process the issuing of the file and the current issuing progress of the file, so as to control effective progress information.

And S65, acquiring the downloading state output to the remote equipment by the terminal equipment.

In a specific example, when the remote device has processed the task of issuing the file and the terminal device downloads the file according to the download instruction of the remote device, the terminal device may synchronously feed back the download status to the remote device, and at this time, the management end may also check the download status of each terminal device from the remote device to actually obtain the download progress.

For the remote device, in an alternative embodiment, as shown in fig. 7 and 5, the method further comprises:

s71, splitting the download files stored in the remote equipment according to the working state, and outputting download instructions of the split files.

In an optional embodiment, the download instruction includes one or more of a download path of the split file at the remote device, a download mode of the remote device, a download path of the terminal device, a download mode of the terminal device, download history information, offset information, length information, and check code information.

In the step, the working state of the terminal equipment and the downloaded file are taken as splitting bases, the remote equipment carries out uniform downloading scheduling on the split file, the file is split into the split files suitable for all the terminal equipment, uniform scheduling and accurate downloading of the terminal equipment are achieved, network waste between the remote equipment and all the terminal equipment can be avoided, and efficient downloading of the file is achieved.

In an optional embodiment, the split file includes a plurality of subfile blocks, and the number of the subfile blocks is determined according to a download requirement of the terminal device that downloads the split file. In this embodiment, on the basis that the split file itself is an incomplete downloaded file, the remote device further performs fragmentation splitting on the split file downloaded by each terminal device according to a working state uploaded by each terminal device, for example, a downloading requirement of the terminal device, and sets the split file as a plurality of subfile blocks.

For example, taking the above 5 terminal devices downloading 100M files as an example, the split file a is 20M and includes 10 sub-file blocks, and then the size of each sub-file block under uniform splitting is 2M. The setting can avoid the problem of repeated downloading of the split file under the condition of resuming the downloading when the split file is abnormally downloaded, so as to further improve the downloading efficiency of the split file.

Illustratively, if the split file is not split twice, the terminal device downloads the split file according to the download instruction, when the terminal device downloads part of the split file, the download is abnormal, and after the download is resumed, the split file is downloaded again.

Therefore, in the embodiment, the split file downloaded by each terminal device is split twice through the remote device, so that after the terminal device recovers to download again due to an abnormal condition, the downloaded subfile block does not need to be downloaded again, thereby improving the downloading efficiency and the resource utilization rate and avoiding repeated downloading.

In an optional embodiment, as shown in fig. 8, the step S71 "splitting the downloaded file stored in the remote device according to the operating status, and outputting a download instruction of each split file", further includes:

and S711, acquiring the working state uploaded by each terminal device.

In an optional embodiment, the working state of each terminal device includes various types of information that can distinguish each terminal device, such as its own gateway information, presence state, routing table information, and the like, and for example, the gateway information includes its own IP address information or machine code information. Through the setting, the remote equipment can realize accurate scheduling and file splitting according to the working state uploaded by each terminal equipment.

S713, the interconnected terminal devices are set to be the same group according to the working state.

In this embodiment, the remote devices and the terminal devices are one-to-many, that is, one remote device corresponds to a plurality of terminal devices, and not all of the terminal devices need to download files. Taking the plurality of terminal devices shown in fig. 3 as an example, the terminal devices not only include a signaling display terminal device for information distribution, but also include a plurality of computer devices for recording running water information, and other different types of terminal devices, and all the devices belong to the same bandwidth network and respectively realize connection with a remote device.

Therefore, for the file to be downloaded of the message display terminal device, the other terminal devices do not need to download the file, in this embodiment, the working states of the terminal devices are grouped, that is, the terminal devices that need to execute the file downloading are set to the same group, and the terminal devices in the group are distributed by splitting the file downloading, so as to realize accurate distribution of the terminal devices that execute the file downloading task.

And S715, generating a splitting file according to the working state and outputting the downloading instruction to each terminal device in the same group.

Illustratively, this step further includes determining the number of split files according to the number of online terminal devices in the same group, and illustratively, as shown in fig. 3, 5 sending display terminal devices are located in the same group of the branch network point, and the total number of sending display terminal devices that need to perform file downloading is 10, but the number of currently online terminal devices is 3, so the remote device of this embodiment splits files according to the number of currently online terminal devices.

For example, taking the aforementioned example of transmitting a 100M file, the remote device may split the file into 5 split files, i.e., each split file may be 20M. Illustratively, 1-20M of split files A are downloaded by the terminal equipment 1, 20-40M of split files B are downloaded by the terminal equipment 2, and by analogy, 80-100M of split files N are downloaded by the terminal equipment 5. Therefore, through the setting, the number of the online terminal devices is maximally matched with the number of the split files, so that the split files downloaded by each terminal device are minimum, and the downloading capacity of the terminal devices is maximally utilized.

It should be noted that, in this embodiment, the size of the split file and the downloading order of the split file by the terminal device are not limited, for example, in the above-mentioned example, the whole file is split averagely, in another specific example, the split file may also be generated in a random splitting manner, and in another example, the size of the split file may also be determined according to resource configurations of different terminal devices, for example, according to a CPU, a memory, and the like of the terminal device, the size of the split file of the terminal device with better performance is set to be larger than the size of the split file of the terminal device with slightly worse performance, so as to further improve the downloading efficiency.

In an optional embodiment, the step S71, "splitting the download file stored in the remote device according to the operating status, and outputting a download instruction of each split file" further includes:

s717, judging whether the terminal equipment finishes downloading at least part of downloaded files according to the working state, and generating a downloading instruction according to a judgment result;

if so, outputting the downloading instruction to other terminal equipment according to the downloading information of the terminal equipment which downloads at least part of the downloading file and outputting the downloading instruction according to the downloading information of the terminal equipment which does not download the downloading file.

In a specific example, when all the terminal devices in the group download the file for the first time, all the online terminal devices download the file from the remote device, and the remote device performs file splitting according to the download information.

In another specific example, when there is a terminal device that does not initially download the file in the group, for example, a part of the file has been downloaded, the remote device splits the file into a first split file downloaded by the existing terminal device and a second split file that is both initially downloaded, and further splits the second split file into a plurality of sub split files according to the number of online terminal devices in the current group. Further, the remote device outputs the download information of the terminal device corresponding to the first split file to other terminal devices for transmission.

In the step, the downloading history of the terminal equipment is analyzed according to the working state of the terminal equipment in the group, so that repeated downloading of the file is avoided, accurate downloading of the file is further realized, and the file downloading efficiency is improved.

And S73, acquiring all downloading information generated when the terminal equipment downloads the split file, and synchronously updating.

In this step, when downloading, the terminal device generates download information, such as a location where the split file is stored, IP information of the local device, and a download state of the local device, such as whether downloading is completed or not, a download progress, and the like, and according to content uploaded by the terminal device, the remote device can obtain the download state of the current file in real time to perform uniform scheduling.

And S75, generating a transmission instruction according to the downloading information, and outputting the downloaded information of the terminal equipment which is downloaded and the transmission instruction to other terminal equipment.

Illustratively, according to the download information obtained in the previous step, the remote device can know whether a terminal device finishes downloading the split file, and if the terminal device finishes downloading, the download information is sent to other terminal devices. In another example, if the number of the terminal devices that have completed downloading the split file is greater than 1, the downloading information of the terminal devices that have completed downloading is output to other terminal devices that have completed downloading, and the mutual transmission of the downloaded split file is preferentially completed.

In an optional embodiment, the method further comprises:

In this embodiment, as described in the foregoing embodiment, after the remote device sets the size of the split file according to the number of terminal devices in the group and outputs the download instruction, a situation that the operating state of the terminal device changes is stored, for example, 4 terminal devices in the same group are in an online state, when the remote device splits the file into 4 split files according to the number of online terminal devices and outputs the download instruction, during the process of executing the download task by the terminal device, there may be a situation that the terminal device executing the task is disconnected, for example, the number of disconnected terminal devices is 3 from 4 online terminal devices, and a situation that the terminal device not allocated with the download task is online also occurs, for example, the number of disconnected terminal devices is newly increased to 5 from 4 online terminal devices, so this embodiment designs a situation that the operating state of the terminal device changes.

Illustratively, when the terminal device executing the task is disconnected, the number of 4 online terminal devices is 3, and after the remote device obtains that the working state of the remote device changes, the remote device re-outputs the downloading instruction and re-allocates the split file, and allocates the downloading instruction of the disconnected terminal device and the split file to be downloaded to the terminal device which normally works. Illustratively, the remote device may reselect the terminal device in a random allocation manner, and in another example, the remote device may further allocate the download instruction of the disconnected terminal device and the split file to be downloaded to the terminal device with the fastest download progress, so as to ensure the download efficiency of the file when the outgoing line is abnormal, and implement timely scheduling of the remote device.

In another example, when a new terminal device in a group is added, 4 online terminal devices are added to 5, and after the remote device acquires that the working state of the terminal device changes, the remote device outputs the download information, such as address information and the download state, of the terminal device which has completed downloading the split file to the new terminal device according to the acquired working state of the terminal device which executes the download task, so that the new terminal device downloads the split file of other terminal devices which are executed first in a local area network interconnected with the group instead of downloading the file from the remote device, thereby avoiding the occupation of a bandwidth network, improving the file download efficiency, and reducing the network pressure on the remote device.

In the embodiment, the remote device splits the download instruction and the file according to the working state of the terminal device, so that unified scheduling of the remote device is realized, each terminal device in the same group downloads the split file according to the download instruction, and respective split files are transmitted between the terminal devices by using the network interconnection characteristics of the same group in the terminal devices, so that the complete file acquisition is realized.

In an optional embodiment, the remote device includes a file server and a cloud computing server, where the file server is configured to store a file uploaded by the management terminal, and the cloud computing server is configured to implement output of a download instruction, computation of file splitting, and allocation of download information, so as to implement uniform scheduling and accurate downloading.

For the terminal device, the method executed by the terminal device is shown in fig. 2 and fig. 5, and the process is now explained:

and S21, each terminal device sends a working state and receives a downloading instruction generated by the remote device corresponding to each terminal device in the same group according to the working state.

In an optional embodiment, the step S21 "each of the terminal devices sends the working status" further includes:

In this embodiment, each terminal device sends its own information to the terminal, so that the remote device groups the terminal devices according to the received operating status, for example, as shown in fig. 3, in a branch network, 5 display terminal devices for information distribution are set as a same group, and the information distribution display terminal devices in the group have different identification IDs in the remote device, so that the remote device can be accurately called in the file downloading process. Illustratively, the routing table information further includes download history information and the like, so that the remote device can split the file accurately when splitting the file.

In an optional embodiment, the number of the split files is determined according to the number of the terminal devices uploaded to the remote device and the operating state, for example, in the operating state in which 5 terminal devices in the group upload to the remote device, there are 4 online terminal devices, that is, 4 current terminal devices capable of downloading files, so that the remote device splits the files into 4 files, and each current online terminal device can realize downloading, thereby maximizing downloading efficiency.

And S23, downloading the split files forming the file by each terminal device according to the downloading instruction, wherein the split files downloaded by each terminal device are not overlapped, and all the split files are spliced to form a complete downloaded file.

The download task is distributed after calculation by the remote device, the split file downloaded by each terminal device is a fragmented complete file, that is, the split file downloaded by each terminal device is not a complete download file, and further, because each terminal device is in the same group, for example, each terminal device is set in the same local area network, the terminal devices in the same group can perform internal file transmission. For example, as shown in fig. 3, the terminal device 1 transmits the downloaded split files a to the terminal devices 2 to 5, by using the scheme, the terminal device 1 can obtain the split files transmitted by other 4 terminal devices, and after the terminal device 1 splices all the split files, a complete file issued by the remote device is formed. Illustratively, the split file includes check code information to ensure that each terminal device performs correct splicing locally.

In an optional embodiment, the split file includes a plurality of subfile blocks, and the number of the subfile blocks is determined according to a download requirement of the terminal device that downloads the split file.

In this embodiment, on the basis that the split file itself is an incomplete downloaded file, the remote device further performs fragmentation splitting on the split file downloaded by each terminal device according to a working state uploaded by each terminal device, for example, a downloading requirement of the terminal device, and sets the split file as a plurality of sub-file blocks, where the split file a is 20M exemplarily including 10 sub-file blocks, and the size of each sub-file block under uniform splitting is 2M. The setting can avoid the problem of repeated downloading of the split file under the condition of resuming the downloading when the split file is abnormally downloaded, so as to further improve the downloading efficiency of the split file.

Illustratively, if the split file is not split twice, the terminal device downloads the split file according to the download instruction, when the terminal device downloads part of the split file, the download is abnormal, and after the download is resumed, the split file is downloaded again. Therefore, the split file downloaded by the terminal device of this embodiment is the subfile block, after the terminal device downloads again, the downloaded subfile block does not need to be downloaded again, and the split subfile block can be used normally, so that the downloading efficiency and the resource utilization rate are improved, and repeated downloading is avoided.

In an optional embodiment, the terminal device downloads the split file by a breakpoint downloading method, that is, the downloading process may be suspended or interrupted, and then the terminal device can continue to download the split file according to the downloaded subfile block and the downloading instruction.

In an optional embodiment, the step S23 "downloading the split file according to the download instruction" further includes:

and if the terminal equipment downloads the split file corresponding to the downloading instruction for the first time, downloading the split file from the remote equipment. In a specific example, when all the terminal devices in the group download the file for the first time, all the online terminal devices download the file from the remote device, and the remote device performs file splitting according to the download information.

And if the terminal equipment in the terminal equipment finishes downloading the split file corresponding to the downloading instruction, downloading the split file from the terminal equipment which finishes downloading.

In another specific example, when there is a terminal device in the group that does not initially download the file, for example, a part of the file has already been downloaded, the remote device splits the file into a first split file downloaded by the existing terminal device and a second split file both initially downloaded. And for the second split file, all the terminal equipment downloads for the first time, and the second split file is downloaded from the remote equipment according to a downloading instruction issued after the remote equipment splits the second split file.

For the first split file, for example, a downloaded partial file already exists in 4 online terminal devices, that is, the partial file is used as the first split file, the remote device outputs information of the terminal device that has downloaded the first split file as a download instruction to other terminal devices that are downloading the first split file, and the other terminal devices transmit the first split file from the intranet according to the download instruction and by using the network characteristics of the same group, instead of downloading the first split file from the remote device, so that accurate downloading of the file is further realized, file downloading efficiency is improved, and network pressure on the remote device is reduced.

And S25, according to the transmission instruction output by the remote equipment, different terminal equipment transmits the downloaded split file in a connection network to acquire the complete downloaded file.

In an optional embodiment, as shown in fig. 9, step S25, "different terminal devices transmit the downloaded split file in a connected network to obtain the complete downloaded file", further includes:

and S251, acquiring the transmission instruction and the downloading information of the terminal equipment after the downloading is finished from the remote equipment.

In this embodiment, the download information includes address information and a download state of the split file at the corresponding terminal device, where the address information is used to specify a storage location where the split file is downloaded by the terminal device, and the download state is used to specify a download progress of the terminal device.

The remote equipment acquires the downloading information of the terminal equipment in real time, generates a transmission instruction after the terminal equipment finishes downloading the corresponding split file, realizes global scheduling of file downloading and enables the terminal equipment to carry out internal transmission from other terminal equipment in the group.

That is, after completing downloading the split file of its own task, the terminal device receives the transmission instruction and the download information of other terminal devices that have completed downloading, and specifies the transmission object of the transmission request, so as to realize transmission of the rest split files by using the internal network.

And S253, generating a file transmission request to other terminal equipment in the connection network according to the transmission instruction and the downloading information.

Illustratively, the terminal device 1 has completed downloading the corresponding split file a, the terminal device 2 has completed downloading the corresponding split file B, the terminal device 3 has completed downloading the corresponding split file C, all three terminal devices have completed downloading the split files of their own tasks, and the remote device generates the transmission instruction according to the download status transmitted by the terminal devices in real time.

For the terminal device 1, the received transmission instruction is to request the terminal device 2 to transmit the split file B, and to request the terminal device 3 to transmit the split file C. For the terminal device 2, the received transmission instruction is to request the terminal device 1 to transmit the split file a, and to request the terminal device 3 to transmit the split file C. For the terminal device 3, the received transmission instruction is to request the terminal device 2 to transmit the split file B, and to request the terminal device 1 to transmit the split file a. Through the steps, the sending object of the transmission request is determined, so that the transmission of the rest split files is realized by utilizing the internal network.

And S255, acquiring other split files from other terminal equipment, and splicing.

For example, after requesting to transmit the split file B to the terminal device 2 and requesting to transmit the split file C to the terminal device 3 for the terminal device 1, high-speed transmission is performed between the terminal device 1 and the terminal device 2 and between the terminal device 1 and the terminal device 3 by using an internal network, and the split file B and the split file C are spliced after being received. Through the setting, the characteristic that the terminal devices in the same group clearly communicate with each other is utilized, the communication efficiency is improved, the mutual transmission of split files is completed, and the downloading of the whole file is completed after the split files are spliced.

In the embodiment, the remote device splits the download instruction and the file according to the working state of the terminal device, so that unified scheduling of the remote device is realized, each terminal device in the same group downloads the split file according to the download instruction, and respective split files are transmitted between the terminal devices by using the network interconnection characteristics of the same group in the terminal devices, so that the complete file is obtained.
