Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The following terms are used herein.

VR, virtual Reality, also known as smart mirror technology, and also known as Virtual Reality in english, refer to a technology for providing an immersive sensation in an interactive three-dimensional environment generated on a computer by comprehensively using a computer graphics system and various interface devices such as Reality and control.

Virtual content, i.e. VR virtual resources, refers to content that can be experienced by VR devices, for example, the virtual content can be divided into: VR games, VR videos, etc.

PC, personal Computer, english full name Personal Computer includes: desktop, notebook, mini notebook, tablet, ultrabook, and the like.

CAVE, a projection-based immersive virtual reality display system.

UDP, user Datagram Protocol, english full name User Datagram Protocol, provides a method for an application program to send an encapsulated IP packet without establishing a connection.

API, application Program Interface, english-language Application Program Interface, application Program can be used to exchange standard set of information and commands with computer operating system.

In the related art, when the virtual simulation training platform is operated, pain points where virtual contents need to be transmitted individually exist. That is to say, in the same time period, based on the virtual simulation training platform, only after one demonstration video is sent, the demonstration video can be sent continuously. For example, in a certain time period, based on the virtual simulation training platform, only after the demonstration video is sent to the terminal device 1, the demonstration video can be sent to the receiving device 2; accordingly, the receiving apparatus 2 can receive the presentation video only after the receiving apparatus 1 has finished receiving the presentation video. Therefore, the whole transmission flow of the virtual content has sequential behavior relation, which greatly reduces the practical training efficiency.

In addition, in the existing deployment scheme of the virtual simulation training platform, since the server is often deployed in a machine room and other specific places and is separated from a real training base place, the virtual simulation training platform often needs to maintain a large number of binding relationships between receiving devices and slave-end plug-ins, which has higher requirements on the virtual simulation training platform itself and hardware facilities such as a network, and accordingly, the maintenance cost is increased, and the universality of the product is reduced.

The embodiment of the application provides a distribution system of virtual content, which is applied to a virtual simulation training platform, wherein a main end plug-in is installed on the virtual simulation training platform; the virtual simulation training platform is used for acquiring information to be distributed and acquiring address information of the virtual content according to the information to be distributed; the virtual simulation training platform is further used for sending the address information of the virtual content to the receiving equipment through the main end plug-in; the information to be distributed comprises information of a receiving device and information of virtual content to be distributed. Because the virtual simulation training platform is provided with the main end plug-in, the virtual content can be distributed in batches based on the main end plug-in, the data transfer efficiency is improved, the virtual content can be rapidly distributed to each receiving device, and the training efficiency is greatly improved. Therefore, the pain point of single transmission of VR virtual content when the virtual simulation training platform is used is solved.

Moreover, in the distribution system of the virtual content provided by the embodiment of the application, the virtual simulation training platform only needs to maintain a small number of main end plug-ins which can be deployed in a real training base site, so that all receiving devices (specifically, slave end plug-ins of the receiving devices) in the same network with the virtual simulation training platform can be quickly searched and collected in a local area network or UDP mode, and further, the communication between the virtual simulation training platform and the receiving devices is facilitated, the training efficiency is improved, the maintenance cost is favorably reduced, and the universality of products is improved.

In practical application, a user may select a desired virtual content through the virtual simulation training platform 10, and select a corresponding receiving device through the issuing function of the virtual simulation training platform 10. For example, a plurality of receiving devices in a certain area range may be selected according to actual requirements, and of course, a single device may also be selected as a receiving device, which is not specifically limited in this embodiment.

The receiving device may be a virtual hardware device that communicates with the virtual simulation training platform 10. Such as VR helmets, VR large screens, CAVE, PCs, and sets of PCs, etc., which the present embodiment is not particularly limited. Further, the receiving device is generally a supporting body of the virtual hardware device, for example, the VR headset needs to be connected with a PC, and the PC is the supporting body.

The information of the receiving device included in the information to be distributed may be identification information for characterizing the receiving device. For example, numbers 1, 2, 3 may be used to identify VR headset 1, VR headset 2, and VR headset 3, respectively; for another example, the letters a, B, C may be used to identify a VR helmet, a VR large screen, and a five-person table, respectively; the information of the receiving device may also be represented by a model of the receiving device, which is not specifically limited in this embodiment.

The information of the virtual content included in the information to be distributed may be identification information for characterizing the virtual content. For example, if the virtual content is related content required for teaching, the letter a may be used to represent teaching content for art, A1 represents a course 1 for the art teaching content, and A2 represents a course 2 for the art teaching content; the information of the pseudo content may be represented by a title of the virtual content, an icon having a special shape, or the like, which is not particularly limited in this embodiment.

In some embodiments of the present application, the device management unit 21 is further configured to determine whether the communication state of the receiving device is normal according to the information to be distributed, obtain a determination result, and send the determination result to the application management unit 22; the application management unit 22 is configured to, when the determination result indicates that the communication state of the receiving device is normal, perform the step of obtaining the address information of the virtual content according to the information to be distributed and sending the address information of the virtual content to the device management unit 21.

That is to say, after acquiring the information to be distributed, the device management unit 21 may first determine whether the receiving device is in an online state. If the receiving device is in the online state, a determination result that the communication state of the receiving device is normal may be obtained, and at this time, the application management unit 22 obtains the address information of the virtual content according to the information to be distributed, and sends the address information of the virtual content to the device management unit 21. If the communication state of the receiving device is in the abnormal state as a result of the determination, the device management unit 21 may not perform any operation, or may only send a prompt message indicating that the communication state of the receiving device is in the abnormal state to the application management unit 22, which may be set according to actual requirements, and this embodiment is not limited in particular.

The device management unit 21 may specifically determine whether the communication state of the receiving device is normal by performing UDP communication and/or actively executing a Ping command.

In some embodiments of the present application, the device management unit 21 is further configured to send the backhaul information to the application management unit 22.

That is, the device management unit 21 notifies the application management unit 22 that the corresponding virtual content has been delivered by transmitting the backhaul information to the application management unit 22.

In some embodiments of the present application, the host plug-in 11 is configured to encrypt the address information of the virtual content, and then send the encrypted address information of the virtual content to the receiving device.

In some embodiments of the present application, the master plug-in 11 is configured to send address information of the virtual content to a slave plug-in of the receiving device.
