Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, in one embodiment, a method for quickly distributing VR resources is provided, and the method specifically includes the following steps:
s1, acquiring resource information of various VR resources to be downloaded, and determining downloading priority of the various VR resources according to the resource information;
s2, acquiring equipment information of each VR equipment in the local area network, and calculating the optimal download proportion and the optimal download sequence of each VR equipment according to the equipment information;
s3, according to the optimal download proportion and the download priority, dividing each VR resource into a plurality of sub-resource packages in sequence, and generating download tasks corresponding to each sub-resource package;
s4, correspondingly distributing the downloading task to each VR device, so that each VR device executes the downloading task according to the optimal downloading sequence and downloads the corresponding sub-resource package;
s5, recovering the downloading result of each VR device, assembling all sub-resource packages of the VR resources after downloading all sub-resource packages of the VR resources, recombining the sub-resource packages into complete resources, and distributing the complete resources to each VR device.
In use, taking VR resources to be downloaded for VR classroom teaching as an example, tens of VR devices can be arranged in a lan of a classroom, and one VR device is provided for a student to use. In the prior related art, a plurality of dozens of VR devices request the VR resource cloud server for downloading, but because VR resources generally occupy a large storage space, under the condition that a plurality of dozens of VR devices request the downloading mode simultaneously, each VR device downloads quickly, the requirements on the cloud server and network bandwidth are high, otherwise, the downloading is seriously blocked, and the problem of overlong downloading time is caused.
In this regard, in this embodiment, a central node for VR resource distribution may be added to the local area network, and the above method is applied to the central node, so as to improve downloading and distribution efficiency of VR resources, and enhance user experience.
Through the method in this embodiment, the central node first obtains resource information of various VR resources to be downloaded, where the various VR resources may include 3D model resources, installation package resources, video resources, audio resources, picture resources, and the like, and determines downloading priorities of the various VR resources according to the resource information, where determining the downloading priorities of the various resources may form a better downloading order of the various VR resources, which is helpful for further improving downloading distribution efficiency of the VR resources.
Next, the central node obtains device information of each VR device in the local area network, where the device information may specifically include: device ID information, electric quantity information, storage capacity information, wiFi SSID information, resource installation information, CPU occupation information, online state information and the like of the VR devices, and calculating optimal download proportion and optimal download sequence of each VR device according to the device information. In the traditional multithreading downloading mode, average task allocation is generally performed according to the size of resources to be loaded and the number of available equipment nodes, but in the environment of VR equipment networking, factors such as the online state, storage space, battery information and the like of each equipment are considered, so that the method of average allocation is not applicable any more, reasonable planning is performed by combining various specific equipment information of each equipment, the optimal and most reasonable downloading strategy can be obtained, and the downloading efficiency is improved.
Then, the central node sequentially splits various VR resources into a plurality of sub-resource packages according to the optimal downloading proportion and downloading priority, generates downloading tasks corresponding to the sub-resource packages, and distributes the downloading tasks to each VR device correspondingly, so that each VR device executes the downloading tasks according to the optimal downloading sequence and downloads the corresponding sub-resource packages. The device which has completed the resource download can continuously provide the download service in the local area network for other devices, and when a plurality of devices can provide the download service, the central node can automatically calculate the optimal device according to the device information of the devices. In this embodiment, each VR device only needs to download a part of various VR resources according to the calculated optimal download proportion, but not all VR devices need to download complete VR resources, and meanwhile, each VR device can download reasonably and orderly according to the calculated optimal download sequence, but not all VR devices download at the same time, so that repeated downloading of a single thread is changed into unique downloading of multiple threads, network congestion caused by simultaneous downloading of multiple devices is effectively avoided, and resource downloading efficiency is improved.
Finally, the center node recovers the downloading result of each VR device, when all sub-resource packages of one VR resource are downloaded, all sub-resource packages of the VR resource are assembled, complete resources are formed again, and the complete resources are distributed to each VR device.
Taking a 500M video resource as an example, the video resource is split into a plurality of sub-resource packets according to the calculated download proportion, and a download task queue corresponding to each sub-resource packet is generated. Each download task may be marked with information such as a resource package id, a start-stop location, a storage state, etc. And when the central node performs task allocation, the central node takes out the downloading tasks from the tasks to be downloaded according to the downloading sequence and allocates the downloading tasks to the corresponding VR equipment. And the VR equipment for obtaining the downloading task reports the downloading result to the central node after the downloading is completed. When all the sub-resource packages of a certain resource are downloaded, the central node assembles all the sub-resource packages to form a complete resource and distributes the complete resource to VR equipment in the local area network, and the VR equipment completes corresponding subsequent processing.
In addition, in this embodiment, specifically, a teaching management system may be installed by one PC, and is responsible for acting as a central node. The equipment information and the resource information can be stored in the cloud end, and the central node uniformly acquires, acquires and manages the equipment information and the resource information from the cloud end. The central node opens the appointed port to provide service and broadcasts own information at regular time. After the VR device (virtual reality device) is accessed to the local area network and started, the information of the central node is received through broadcasting, the information of the device is reported, and meanwhile, the device starts service at a designated port so as to receive a downloading instruction of the central node.
Further, in an embodiment, the resource information includes: the loading sequence and loading frequency of VR resources;
in step S1, determining the downloading priority of each VR resource according to the resource information, which specifically includes:
tracking and recording the loading sequence and loading frequency of various VR resources by using an event notification mechanism;
calculating the weights of various VR resources based on a CRITIC weight algorithm, the loading sequence and the loading frequency of various VR resources;
and determining the downloading priority of each VR resource according to the weights of each VR resource.
In this embodiment, a unified method may be used to load various VR resources to be downloaded in an application scenario, so as to track the loading sequence and loading frequency of various VR resources, assign different downloading weights to various resources, and further determine the downloading priority of various resources, which may be specifically reflected in that the greater the weight value, the higher the priority, and the weight information is unified managed by the central node.
Specifically, when a class of resources are loaded by using an event notification mechanism of C#, the loading sequence and the loading frequency of the loaded resources are notified by the event mechanism to track and record, then the weight calculation is performed by using the fluctuation of data or the correlation condition between the data based on a CRITIC weight algorithm, the calculation result is locally stored and reported, the central node performs comprehensive calculation after receiving the correlation data, finally the downloading priority of various relatively optimal VR resources is obtained, and the downloading priority is reversely notified to the client. After the priority order of the downloading of the first kind of resources tends to be stable, the central node stops the calculation work so as to reduce the occupation of the resources related to the equipment and prolong the service time of the battery. Meanwhile, related code specifications can be formulated to restrict and track the loading sequence and loading frequency of resources, and a certain download weight adjustment authority can be set to ensure that the adjustment is interfered when an ideal scheme cannot be calculated. The downloading priority of the resources is determined based on the resource loading sequence and the loading frequency, so that the resources which are used first and frequently can be downloaded preferentially can be ensured, the use habit and the requirement of a user can be effectively met, and the user experience is improved.
Further, in an embodiment, the method further includes:
and acquiring the real-time bandwidth use condition of the public network, and acquiring the resource information of various VR resources to be downloaded when the load rate of the real-time bandwidth use of the public network is lower than a preset threshold value.
In a specific use process, when the load rate of the public network bandwidth is too high, the network utilization rate is too high at this time, and other works are performed to possibly cause network breakdown, so that before the method is implemented, the central node of the application needs to acquire the public network bandwidth utilization condition, and when the load rate of the public network real-time bandwidth utilization is determined to be lower than a preset threshold value, resource information of various VR resources to be downloaded is acquired, and subsequent processing is performed to avoid network breakdown caused by the too high network load, and the work cannot be performed normally.
Further, in an embodiment, in step S5, the distributing the complete resource to each VR device specifically includes:
and carrying out integrity check on the reconstituted complete resource, and when the integrity check is true, identifying the complete resource as a usable state and distributing the usable state to each VR device.
In this embodiment, after sub-resource packages of various resources are assembled to form complete resources, integrity verification is performed on the complete resources, and when the integrity verification is true, that is, after the complete resources are verified to be complete resources, the complete resources are identified as usable states and distributed to each VR device, so that incomplete assembly of resources is avoided, and the use effect of subsequent resources is prevented from being affected.
Further, in an embodiment, the method further includes: and setting a monitoring terminal, and sending the downloading progress of each VR device to the monitoring terminal for monitoring.
In this embodiment, the central node may further be provided with a monitoring terminal, which can effectively help a teacher monitor the downloading conditions of each VR device in the class with the monitoring terminal, so as to facilitate management.
