Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a remote synchronization file-pushing caching method based on VR devices according to a preferred embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
and S100, the central controller sends a link command to the VR equipment and establishes connection with the VR equipment, and the VR equipment feeds back a successful connection result to the central controller.
And S200, the central controller sends the synchronous file list to VR equipment through a command transmission channel.
And step S300, the VR equipment receives and compares the local file list with a synchronous file list sent by the central controller, and then feeds back the synchronous state to the central controller.
And S400, the central controller transmits and caches/downloads files corresponding to the synchronous file list to VR equipment through a file transmission server.
The VR equipment is connected with the central controller through a wireless communication network; the command transmission channel is a TCP/UDP command transmission protocol and is used for information exchange between the central controller and VR equipment, and the file transmission server is a Web server and is used for file transmission of the VR equipment by the central controller.
Note that the central controller is a Personal Computer (PC), and includes: the device can independently operate and complete specific functions, such as a desktop computer, an all-in-one machine, a notebook computer, a palm computer, a tablet computer and the like. Among TCP/UDP command transmission protocols, the TCP (transmission Control protocol) and UDP (user datagrampprotocol) protocols belong to the transport layer protocol. The services provided by TCP include data stream transmission, reliability, effective flow control, full duplex operation and multiplexing, and are sent by connection-oriented, end-to-end and reliable data packets; while UDP does not provide reliability, flow control or error recovery functions. Generally, TCP corresponds to applications with high reliability requirements, while UDP corresponds to applications with low reliability requirements and economical transmission. Colloquially, the TCP/UDP protocol is a mature technology, and is often used to handle the communication protocol between the central controller end and the VR device end. The Web server is also a mature technology, and is mainly used for processing requests of the VR device, and requests and transfers of files can reach the transfer speed of the lan network in the lan.
In addition, VR equipment is one or more, VR equipment passes through wireless communication network with central controller and is connected, like bluetooth, wiFi, GPRS etc..
In specific implementation, firstly, under the same local area network, the central controller sends a link command to the VR device through a TCP/UDP protocol to establish a connection with the VR device, then the central controller monitors whether the VR device is successfully connected in real time, after the connection is successful, the VR device feeds back a successful connection result to the central controller, once the central controller receives the successful connection result fed back by the VR device, the central controller sends a synchronization file list to the VR device through the TCP/UDP protocol, after receiving the synchronization file list, the VR device compares whether the synchronization file list is matched (i.e. consistent) with the local file list, and when the local file list is matched with the synchronization file list sent by the central controller, the synchronized state is fed back to the central controller, that is, the central controller is informed that all file lists required to be synchronized are synchronized successfully, and then the central controller transmits the file corresponding to the synchronous file list to the VR equipment through a file transmission server and caches/downloads the file at the VR equipment.
In a further embodiment, the VR device-based remote synchronous push file caching method further includes:
the VR equipment receives and compares the local file list with the synchronous file list sent by the central controller, and then feeds back an unsynchronized state to the central controller; the central controller exchanges the current file list state with the VR device and adjusts the current file list state, so that the local file list of the VR device is matched with the synchronous file list sent by the central controller.
In a further embodiment, the specific steps of receiving and comparing by the VR device that the local file list does not match the synchronization file list sent by the central controller include:
the central controller exchanges file directory information with the VR device through the command transmission channel and sets the matching degree of the directory information to be unsynchronized.
The central controller resends the list of synchronization files to the VR device, and the adjustment matches the local file list of the VR device with the list of synchronization files sent by the central controller.
In specific implementation, the VR device receives and compares that the local file list is not matched with the synchronized file list sent by the central controller, that is, if the files are not matched, it indicates that the file to be synchronized has changed, at this time, an unsynchronized state needs to be fed back to the central controller, the central controller exchanges file directory information with the VR device through a command transmission channel and sets the matching degree of the directory information to be unsynchronized, meanwhile, the states of all VR devices are set to be unsynchronized, then the central controller resends the synchronized file list to the VR device, and the VR device receives and compares the local file list again until the local file list of the VR device is adjusted to be matched with the synchronized file list sent by the central controller.
It can be seen that, after the central controller is successfully connected with the VR device, the central controller first sends a file list to be synchronized to the VR device end through the command transmission channel, and when the central controller end matches (i.e. is consistent with) the synchronization list of the VR device end, the file corresponding to the synchronization file list is transmitted to the VR device through the file transmission server and cached/downloaded at the VR device end, and when the VR device receives and compares that the local file list is not matched with the synchronization file list sent by the central controller, an unsynchronized state is fed back to the central controller; the central controller exchanges the current file list state with the VR device and adjusts the current file list state, so that the local file list of the VR device is matched with the synchronous file list sent by the central controller. Therefore, the method of the invention not only can uniformly manage one or more VR devices by synchronizing files, but also only needs to confirm whether the central controller and the VR devices are synchronized when a large amount of VR devices need to receive the same files, and does not need to consider how to cache/download the files to the VR devices. For example, in a large VR studio site, the demonstration contents of dozens of or hundreds of VR devices need to be consistent, the method can be easily realized, and the problem of errors caused by errors when files are manually and manually operated and transmitted is solved.
Further, as shown in fig. 2, the step S400 specifically includes:
s401, starting a file transmission server.
S402, the file transmission server sends the file transmission path information list to VR equipment.
S403, the VR equipment compares the local file list and generates a synchronization instruction set.
And S404, executing the instruction set and feeding back the current synchronization state to the central controller.
S405, after the instruction set is executed, the file is successfully synchronized and cached/downloaded to VR equipment.
In specific implementation, when the central controller receives a synchronized state fed back by the VR device, the file transmission server is started, first, the file transmission server sends a file transmission path information list to the VR device, the VR device compares the local file list and generates a synchronization instruction set, the synchronization instruction set is generated and starts to be executed, and simultaneously feeds back a current synchronization state to the central controller, the current synchronization state is normally in synchronization, and when the instruction set is executed, a synchronization completion state is fed back to the central controller, which indicates that the file is successfully synchronized and cached/downloaded to the VR device.
Based on the above method, the present invention further provides a VR device-based remote synchronous file pushing cache system, as shown in fig. 3, the system includes:
the central controller 100 is configured to send instruction information and transmit a file corresponding to the synchronization file list to the VR device connected to the file; as described above.
