[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0027] The purpose of this invention is to address the shortcomings of existing technologies by providing a VR glasses signal direct connection device based on multi-protocol matching.

[0028] Example 1

[0029] This embodiment provides a VR glasses signal direct connection device based on multi-protocol matching, such as... Figure 1-4 As shown, it includes a terminal interface module 1, a signal conversion module 2, a multi-protocol adaptation module 3, a millimeter-wave transmission module 4, and an intelligent resource management module 5.

[0030] Signal conversion unit 2 is the input terminal of the entire device. It establishes a physical connection with external devices (such as computers and mobile phones) through hardware interfaces (such as HDMI, USB-C, etc.). The model is TIDP83867. It is responsible for receiving data signals sent by external devices. The data signals can be video signals, audio signals, control signals, application signals, etc. The received data signals are converted into standard format signals adapted to the internal processing of VR glasses using a high-speed analog-to-digital converter or digital signal processor of model ADIAD9213, ensuring that the data signals are not distorted and the delay is minimized during the conversion process. In this embodiment, signal conversion unit 2 first identifies the format and encoding method of the received data signal. Assuming that the received signal is an analog signal, it uses a high-speed analog-to-digital converter to convert the analog signal into a digital signal. Then, it performs decoding, format conversion and other operations on the digital signal to convert it into a standard format signal adapted to the internal processing of VR glasses. Finally, the processed standard format signal is sent to the multi-protocol adaptation module 3 through the internal interface for further processing.

[0031] The multi-protocol adapter module 3 is connected to the signal conversion unit 2 via a signal line. The model is Nordic nRF52840. The multi-protocol adapter module 3 includes multiple sub-protocol identification units 31 and a dynamic switching controller 32.

[0032] The sub-protocol identification unit 31 implements a dedicated decoder and encoder (model Ambarella CV22 / CV25) through hardware acceleration circuits, and each decoder and encoder is implemented by an independent hardware acceleration circuit to improve the speed and accuracy of protocol identification. In this way, it can identify the characteristic signals of different communication protocols (such as Bluetooth, Wi-Fi 2.4GHz / 5GHz, millimeter wave, etc.) and accurately determine the protocol type of the external device.

[0033] The dynamic switching controller 32 selects the optimal communication protocol for signal transmission based on a pre-set priority list and real-time network environment parameters (such as signal strength, channel utilization, and latency). It converts the signal into a standard format compatible with the VR glasses' internal processing, ensuring that data from different external devices can be correctly processed within the VR glasses.

[0034] When the external environment changes or the transmission quality deteriorates, the dynamic switching controller 32 will automatically trigger the protocol switching process through control signals to select a better protocol without manual intervention, thus ensuring the stability and efficiency of transmission.

[0035] The millimeter-wave transmission module 4 is connected to the multi-protocol adapter module 3 via a signal line. The module is an Analog Devices AD9371. The millimeter-wave transmission module 4 includes a millimeter-wave transmitter 41, a millimeter-wave receiver 42, an adaptive beamforming antenna array 43, and a power adjustment unit 44. The millimeter-wave transmitter 41 and the millimeter-wave receiver 42 are connected via radio frequency circuits. The adaptive beamforming antenna array 43 includes a first adaptive beamforming antenna array and a second adaptive beamforming antenna array.

[0036] The first adaptive beamforming antenna array is integrated into the millimeter-wave transmitter 41, and the second adaptive beamforming antenna array is integrated into the millimeter-wave receiver 42. Both the first and second adaptive beamforming antenna arrays consist of multiple antenna elements and are typically installed inside the device's housing, near the antenna sections of the millimeter-wave transmitter 41 and the millimeter-wave receiver 42. Both the first and second adaptive beamforming antenna arrays dynamically adjust the beam direction by controlling the phase and amplitude of each antenna element, ensuring the signal is always directed towards the VR glasses, optimizing signal coverage and transmission stability, and improving the reliability and efficiency of signal transmission. In VR glasses applications, this antenna array can adjust the beam in real time according to the user's head position and direction to ensure stable signal transmission.

[0037] The power adjustment unit 44 is located within the internal circuitry of the millimeter-wave transmitter 41, integrated with the transmitter's own power amplifier and control circuitry. It dynamically adjusts the transmission power of the millimeter-wave transmitter 41 based on transmission distance and environmental interference. Power is reduced for short-distance transmission to minimize energy consumption and interference, while power is increased for long-distance transmission or in environments with significant interference to ensure signal quality. This dynamic adjustment mechanism helps optimize energy consumption, extend equipment lifespan, and reduce interference to the surrounding environment.

[0038] The millimeter-wave transmitter 41 modulates the digital signal processed by the multi-protocol adapter module 3 into the millimeter-wave band. Common modulation methods include quadrature amplitude modulation (QAM) and phase shift keying (PSK). Then, it amplifies the modulated signal to sufficient power through its own power amplifier to ensure effective signal transmission. The amplified millimeter-wave band signal is then transmitted through the first adaptive beamforming antenna array. The first adaptive beamforming antenna array adjusts the beam direction according to the position of the VR glasses, and the power adjustment unit 44 adjusts the transmission power according to the transmission conditions.

[0039] The millimeter-wave receiver 42 captures signals in the millimeter-wave band via a second adaptive beamforming antenna array, and performs low-noise amplification on the received millimeter-wave band signals to compensate for signal attenuation during transmission. The amplified millimeter-wave signal is then demodulated into a digital signal to recover the original data. The second adaptive beamforming antenna array adjusts the beam direction to optimize reception.

[0040] Terminal interface module 1 and millimeter-wave transmission module 4 are connected via a signal cable, model AM8269D. Terminal interface module 1 is the output end of the VR glasses signal direct connection device, supporting multiple physical interface forms such as HDMI, USB-C, and DisplayPort, adapting to different models of VR glasses devices, and enhancing the versatility and flexibility of the device; terminal interface module 1 has a built-in signal amplifier to compensate for signal attenuation that may occur during long-distance transmission.

[0041] The terminal interface module 1 acquires the signal received by the millimeter-wave receiver 42, performs processing such as format conversion and signal amplification to ensure signal integrity and quality, and outputs the processed signal to the display module of the VR glasses through a compatible physical interface (such as HDMI, USB-C, DisplayPort, etc.).

[0042] The intelligent resource management module 5 in this embodiment is a Qualcomm Snapdragon XR, used to monitor data traffic, network congestion, and device load status in real time, and dynamically adjust transmission strategies based on the monitoring results. The intelligent resource management module 5 includes a distributed caching unit 51 and a load balancer 52.

[0043] The distributed cache unit 51 is used to temporarily store frequently accessed data, thereby reducing bandwidth consumption by reducing repeated transmissions.

[0044] When certain data is frequently requested, the system stores this data in distributed cache unit 51. Subsequent requests for the same data can be retrieved directly from the cache, avoiding repeated retrieval of data from the source, thereby reducing network bandwidth consumption. Distributed cache unit 51 periodically cleans up expired or infrequently used data according to a certain eviction policy (such as the least recently used policy) to ensure the effectiveness and efficiency of distributed cache unit 51.

[0045] The load balancer 52 is used to reasonably distribute and schedule data streams to optimize the load of each communication link, avoid network congestion and resource waste, and ensure the efficient and stable operation of the system.

[0046] The load balancer 52 monitors the usage of each communication link in real time, including metrics such as bandwidth utilization, latency, and packet loss rate. When the load on a certain link is too high, the load balancer 52 will transfer some data flow to other links with lower load, thereby achieving balanced load distribution and improving the overall system's data transmission capacity and stability.

[0047] The intelligent resource management module 5 is connected to the multi-protocol adaptation module 3 via an internal data bus. The intelligent resource management module 5 receives data signals processed by the multi-protocol adaptation module 3; this data undergoes protocol conversion and optimization to adapt to the standard format processed internally by the VR glasses. The intelligent resource management module 5 temporarily stores frequently accessed data through a distributed cache unit 51, reducing redundant transmissions and lowering bandwidth consumption. Simultaneously, based on the decision of the load balancer 52, the data is transmitted to the millimeter-wave transmission module 4.

[0048] The intelligent resource management module 5 can also dynamically adjust transmission strategies based on the data characteristics and network conditions provided by the multi-protocol adaptation module 3. For example, it can rationally allocate bandwidth resources according to the data traffic characteristics under different protocols to ensure efficient data transmission.

[0049] The intelligent resource management module 5 is connected to the millimeter-wave transmission module 4 via an internal data bus. The millimeter-wave transmission module 4 sends the modulated and amplified signal to the VR glasses. The intelligent resource management module 5 receives signal quality information (such as signal-to-noise ratio and latency) from the millimeter-wave transmission module 4 through a real-time monitoring module. Based on the information from the power adjustment unit of the millimeter-wave transmission module, the intelligent resource management module 5 participates in the decision-making of power adjustment strategies, dynamically adjusts the transmission power, optimizes the data transmission path and rate, and ensures efficient data transmission in the millimeter-wave band 4.

[0050] The intelligent resource management module 5 connects to the terminal interface module 1 via an internal data bus, optimizing the data flow transmitted to the terminal interface module 1 to ensure efficient and stable data output to the VR glasses' display module. It rationally allocates data traffic based on the load status of the terminal interface module 1, preventing overload of the interface unit.

[0051] In this embodiment, the intelligent resource management module 5 provides a stable and high-quality signal to the terminal interface module 1 through load balancing and cache management. This helps improve the display effect and interactive experience of VR glasses, ensuring that users have a smooth and immersive experience.

[0052] The working principle of a VR glasses signal direct connection device based on multi-protocol matching in this embodiment is as follows:

[0053] External devices send data signals to signal conversion module 2 via a physical interface. Signal conversion module 2 converts the received signals into a standard format and then transmits them to multi-protocol adaptation module 3. The sub-protocol identification unit 31 in multi-protocol adaptation module 3 identifies the communication protocol type of the current signal, and the dynamic switching controller 32 selects the optimal protocol based on the network environment and completes seamless switching between protocols. The processed signal enters millimeter-wave transmission module 4, achieving high-bandwidth, low-latency transmission over short distances through millimeter-wave transmitter 41 and millimeter-wave receiver 42. Adaptive beamforming antenna array 43 adjusts the beam direction to optimize signal coverage, and power adjustment unit 44 dynamically adjusts the transmission power based on environmental parameters. Millimeter-wave transmission module 4 transmits the signal to terminal interface module 1, which outputs the signal to the VR glasses' display module via a physical interface. During this data transmission process, the distributed cache unit 51 of intelligent resource management module 5 stores frequently accessed data, and load balancer 52 optimizes data flow distribution.

[0054] It should be noted that the VR glasses signal direct connection device based on multi-protocol matching in this embodiment improves the circuit and structure of the device, but does not involve improvements to the computer. The processing methods can be implemented according to the existing products corresponding to the model.

[0055] Compared to existing technologies, this invention supports multiple communication protocols such as Bluetooth, Wi-Fi 2.4GHz / 5GHz, and millimeter wave, accurately identifying and quickly switching protocols to enable seamless connection between VR glasses and external devices using different protocols, breaking down protocol barriers and improving versatility. Furthermore, it utilizes millimeter wave technology for short-range, high-speed, low-latency transmission, ensuring rapid transmission of high-definition video streams and real-time interactive data. The intelligent resource management module stores frequently accessed data through distributed caching, reducing redundant transmissions and lowering bandwidth consumption. The dynamic switching controller automatically selects the optimal protocol based on network conditions, avoiding transmission interruptions caused by protocol incompatibility or network interference. The adaptive beamforming antenna array and power adjustment module optimize millimeter wave signal transmission, reducing energy consumption and interference, and ensuring signal stability. Integrating multiple communication protocol adaptation and optimization functions reduces reliance on external relay devices, simplifies the system architecture for VR glasses signal transmission, lowers costs and complexity, and improves portability and ease of use.

[0056] Example 2

[0057] This embodiment provides a VR headset, such as Figure 5 As shown, this is a VR glasses signal direct connection device based on multi-protocol matching, as described in Embodiment 1, which includes a VR glasses body and a connection to the VR glasses body.

[0058] The VR glasses signal direct connection device in Embodiment 1 connects to the VR glasses body via a terminal interface module. The terminal interface module, as the output end of the signal direct connection device, transmits the processed signal to the VR glasses' display module via a physical interface (such as HDMI, USB-C, DisplayPort, etc.).

[0059] The VR glasses also establish a wireless communication connection with external devices such as smartphones, computers, or game consoles through the signal direct connection device in Embodiment 1.

[0060] In this embodiment, the VR glasses signal direct connection device and the VR headset are directly connected, reducing the weight of the VR glasses by physically isolating them. During screen projection, data is directly projected onto the VR glasses, eliminating the need for a relay.

[0061] Taking a multiplayer online game scenario as an example, external devices send high-definition video streams and interactive data signals to the signal conversion module through a physical interface. The high-speed analog-to-digital converter and digital signal processor in the signal conversion module process the received data signals, converting them into standard format signals adapted to the processing capabilities of VR glasses. During this process, the signal conversion module ensures that the data signals are not distorted and that latency is minimized during conversion, thereby providing high-quality input signals for subsequent stages.

[0062] Subsequently, the standard format signal is transmitted to the multi-protocol adaptation module via the data bus. The sub-protocol identification unit within the multi-protocol adaptation module is designed with dedicated decoders and encoders for communication protocols such as Bluetooth, Wi-Fi 2.4GHz / 5GHz, and millimeter wave. Each decoder and encoder is implemented with independent hardware acceleration circuitry to improve the speed and accuracy of protocol identification. The dynamic switching controller sorts the available communication protocols according to a preset priority list and selects the optimal protocol based on real-time network quality parameters (such as signal strength, channel utilization, and latency). For example, in a network environment where the Wi-Fi signal is strong but channel congestion exists, the dynamic switching controller automatically selects the millimeter wave communication protocol as the transmission method and triggers the protocol switching process through control signals, without user intervention. This process significantly improves protocol compatibility and system stability.

[0063] The processed signal enters the millimeter-wave transmission module. The millimeter-wave transmitter and receiver are connected via radio frequency circuitry, responsible for signal transmission and reception respectively. An adaptive beamforming antenna array is integrated into both the transmitter and receiver, optimizing signal coverage and transmission stability by adjusting the beam direction. For example, when the VR headset wearer moves their head, the adaptive beamforming antenna array can quickly adjust the beam direction to ensure stable signal transmission. Furthermore, the power adjustment unit dynamically adjusts the transmission power based on transmission distance and environmental interference to reduce energy consumption and signal interference. For instance, during short-distance transmission, the power adjustment unit reduces the transmission power to minimize interference with surrounding equipment and extend device battery life.

[0064] The millimeter-wave transmission module transmits signals to the terminal interface module. This module supports multiple physical interface types, including HDMI, USB-C, and DisplayPort, to adapt to different VR headset models. The terminal interface module incorporates a signal amplifier to compensate for signal attenuation that may occur during long-distance transmission. For example, after long-distance transmission, the signal amplifier amplifies the signal to ensure it can be correctly interpreted by the VR headset's display module or computing unit. The terminal interface module then outputs the signal to the VR headset's display module via a physical interface, enabling a highly immersive and real-time interactive gaming experience.

[0065] In this embodiment, during the above processing, the distributed caching unit of the intelligent resource management module is used to temporarily store frequently accessed data, reducing bandwidth consumption by minimizing redundant transmissions. For example, in multiplayer online games, certain frequently updated game status data is stored in the distributed caching unit to avoid bandwidth waste due to frequent transmissions. The load balancer analyzes the usage of each communication link and distributes data streams to idle or low-load links to avoid channel congestion. For example, when a communication link is overloaded, the load balancer will distribute some data streams to other links, thereby ensuring the efficient operation of the overall system.

[0066] Through the steps described above, this embodiment achieves low-latency, high-stability transmission of high-definition video streams and interactive data, solving the problems of insufficient protocol compatibility, low transmission efficiency, and complex system architecture in existing technologies. For example, in multiplayer online games, players can experience real-time changes in the game screen and operational feedback without experiencing lag or delay. This high-performance signal transmission capability significantly enhances the user experience and meets the needs of modern VR applications.

[0067] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
