[0054] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0056] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0057] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0058] Traditional smart wearables and VR / AR glasses typically employ a high-performance SOC single-system design. However, such designs result in very high standby power consumption and power consumption for applications such as live streaming, Bluetooth music playback, and voice chat, which is not conducive to extended usage time. Furthermore, due to space constraints, battery capacity cannot be continuously increased. Under the current limited design space, in order to pursue both low power consumption (long usage time) and high performance requirements, this invention adopts a dual-system design, using a SOC + MCU two-in-one solution. The various systems are separated, rebuilt, and independently developed to meet the product combination requirements of lower power consumption and high performance.
[0059] like Figure 1 As shown, this invention proposes a low-power dual-system architecture based on AR&VR. The AR&VR-based low-power dual-system architecture includes: a SOC control unit 200 and an MCU control unit 100; the SOC control unit is connected to the MCU control unit 100, and both the SOC control unit and the MCU control unit 100 are connected to a load within the AR&VR system; the MCU control unit 100 is used to control the load to operate when the load's power consumption is lower than a set power consumption; the MCU control unit 100 is also used to send a start signal to the SOC control unit when the load's power consumption is not lower than the set power consumption; the SOC control unit is used to start and control the load to operate upon receiving the start signal; the SOC control unit is also used to enter a standby state if it does not detect that the load's power consumption is not lower than the set power consumption within a preset time period.
[0060] It should be noted that the SOC (System on Chip) control unit 200 and the MCU (Microcontroller Unit) control unit 100 are two different types of embedded control chips. The SOC control unit 200 is highly integrated, typically integrating a CPU, GPU, NPU (Neural Processing Unit), ISP (Image Signal Processor), communication modules (such as 5G / Wi-Fi / Bluetooth), memory controller, peripheral interfaces, and other functional modules, making it suitable for handling complex computing tasks. The MCU control unit 100 has low integration, typically integrating a CPU, limited memory (such as Flash / RAM), timers, ADC / DAC, communication interfaces (such as UART / SPI / I2C), etc., but its functions are relatively simple, making it suitable for handling simple control tasks. The SOC control unit 200 has high power consumption; due to its high integration and strong performance, its power consumption is usually high, making it suitable for scenarios requiring continuous high-performance operation. The MCU control unit 100 has low power consumption, used in low-power scenarios, and supports multiple low-power modes (such as sleep mode and standby mode), making it suitable for battery-powered devices.
[0061] Understandably, the dual-system design using a low-power MCU control unit 100 and a high-performance SOC control unit 200 completely solves the high power consumption issues in standby, Bluetooth music playback, and voice chat applications that traditional smart wearables and VR / AR glasses use a single high-performance SOC system. In conventional SOC system designs, because all functionalities (peripheral interfaces, audio / video codec integration, and wireless Bluetooth / WIFI integration) need to be integrated, the high-performance SOC processor is required for standby, regular voice chat, and Bluetooth music playback, thus offering no advantage in low power consumption. This invention employs a dual-system design, completely separating the processors used for frequently used low-power applications from those used for high-power applications. When the product's most common standby, regular voice chat, and Bluetooth music playback scenarios occur, only the MCU control unit 100 operates, while the SOC control unit 200 is put into sleep mode. The SOC control unit 200 is only activated when the product requires video streaming, photo transmission, software upgrades, or WIFI transmission. This design ensures that the most common applications operate at the lowest power consumption while retaining the product's high-performance application requirements.
[0062] Specifically, the SOC control unit 200 includes, but is not limited to, a high-performance processor, used in high-performance application scenarios such as live video streaming, image transmission, software upgrades, and Wi-Fi transmission. The MCU control unit 100 includes, but is not limited to, a low-power control processing unit. The MCU control unit 100 and the SOC control unit 200 are mainly connected via two interrupt GPIO ports: one GPIO for the MCU control unit 100 to wake up the SOC control unit 200, and the other GPIO for the SOC control unit 200 to wake up the MCU control unit 100. The MCU control unit 100 and the SOC control unit 200 are also connected via SPI for image and large data transmission communication, via UART for small data transmission and handshake communication, and via I2S for audio data transmission in recording or audio / video scenarios.
[0063] It's important to note that GPIO, short for General Purpose Input / Output Port, refers to the functional pins of a chip. SPI, short for Serial Peripheral Interface, is a high-speed, full-duplex, synchronous communication bus. UART, short for Universal Asynchronous Receiver / Transmitter, is a serial data bus used for asynchronous communication, primarily for data transmission in embedded systems. I2C, short for Inter-Integrated Circuit, is a serial communication bus.
[0064] In this embodiment, the invention employs a dual-system design, completely separating the processors for frequently used low-power applications from those for high-performance applications. When the product is in standby, using voice chat, or playing Bluetooth music, only the MCU runs, while the SOC is put into sleep mode. The SOC is only activated when the product requires high-performance scenarios such as live video streaming, photo transmission, software upgrades, or Wi-Fi transmission. This invention ensures that the most common applications run at the lowest power consumption while preserving the product's high-performance application requirements.
[0065] like Figure 2 As shown, Figure 2 This is a circuit diagram of a second embodiment of the low-power dual-system architecture based on AR & VR provided by the present invention.
[0066] Based on the first embodiment described above, a second embodiment of the low-power dual-system architecture based on AR & VR of the present invention is proposed.
[0067] The structure further includes a power supply unit; the power supply unit includes a power management unit 500, a charging IC unit 300, and a battery module unit 400; the power management unit 500 is connected to the SOC control unit 200 and the MCU control unit 100, and is used to provide the required operating voltage to the SOC control unit 200 when receiving an enable signal output by the MCU control unit 100, so that the SOC control unit 200 can be powered on and reset; the charging IC unit 300 is connected to the battery module unit 400 and the MCU control unit 100 respectively, and is used to control the battery module unit 400 to provide the required operating voltage to the MCU control unit 100 when receiving a power supply command.
[0068] It is understood that the power management unit 500 and the SOC control unit 200 are mainly connected via CLK clock and LDOs / Bucks, used to power the SOC control unit 200 and provide the system clock. The power-on interface of the power management unit PMIC and the reset interface of the SOC control unit 200 are connected to the MCU control unit 100 via two GPIO ports, allowing the MCU control unit 100 to control the power-on and reset of the SOC control unit 200. The charging IC unit 300 includes, but is not limited to, a charging IC unit 300 and a fuel gauge. The charging IC unit 300 is mainly connected to the MCU control unit 100 via I2C & GPIO external interrupts and VCC power supply, primarily used to power the MCU charging IC unit 300, manage battery charging, and manage battery power. The battery module unit 400 includes, but is not limited to, a battery module unit 400, connected to the charging IC, used to power the MCU control unit 100. The charging IC establishes a connection with the battery and charger in the mobile device through internal analog and digital circuits, monitoring and controlling the current and voltage during the charging process.
[0069] Specifically, such as Figure 3 As shown, the charging management of the present invention is as follows: when the device is powered off, the charging data cable is inserted, and it is detected whether the MCU control unit 100 is turned on. When the MCU control unit 100 is not turned on, the device is charged by a hardware preset current and the charging LED indicates that it is charging. When the MCU control unit 100 is turned on, the MCU control unit 100 receives charging interruption, charging input detection and battery temperature detection, displays the power level, sets the charging current according to the detection, and indicates the operation of the RGB charging IC.
[0070] The structure further includes a communication circuit; the communication circuit includes a radio frequency Wi-Fi communication circuit 800, a Bluetooth communication circuit 600, and a network communication circuit 700; the Bluetooth communication circuit 600 is connected to the MCU control unit 100 and is used to control the MCU control unit 100 to connect to the communication device and perform Bluetooth data transmission; the radio frequency Wi-Fi communication circuit 800 is connected to the SOC control unit 200 and the MCU control unit 100, and is used for Wi-Fi data transmission control, and also for data packet traffic arbitration during Bluetooth data transmission; the network communication circuit 700 is connected to the MCU control unit 100 and is used for software download and debugging according to the commands of the MCU control unit 100.
[0071] Understandably, the RF Wi-Fi communication circuit 800 and the SOC control unit 200 are mainly connected via the PCIe interface and the Wi-Fi control GPIO port. The RF Wi-Fi communication circuit 800 is also connected to the PTA interface of the MCU control unit, primarily used for Wi-Fi data transmission control and data packet traffic arbitration in scenarios such as live video streaming, photo transmission, software upgrades, and Wi-Fi transmission when the mobile phone is also connected to Bluetooth. Wi-Fi, also known as "mobile hotspot," is a trademark of the Wi-Fi Alliance manufacturers used as a brand certification for their products. It is a wireless local area network communication technology based on the IEEE 802.11 standard. RF stands for Radio Frequency, referring to radio frequency in wireless communication.
[0072] It should be noted that the Bluetooth communication circuit 600 and the MCU control unit 100 are mainly connected through the BT design interface, used for low-power connection of mobile phones and communication management, Bluetooth music, image transmission and recognition, voice chat, Bluetooth data transmission, etc. BT stands for Bluetooth radio frequency communication. The network communication circuit 700 includes download and debug ports, and is mainly connected to the MCU control unit 100 through UART, mainly used for software download and debugging. A Universal Asynchronous Receiver / Transmitter (UART) is a serial data bus used for asynchronous communication, mainly for data transmission in embedded systems.
[0073] The structure further includes a hardware unit; the hardware unit includes a storage control unit 1000 and a drive display unit 900; the storage control unit 1000 is connected to the SOC control unit 200 and is used to store the operating data of the SOC control unit 200; the drive display unit 900 is connected to the MCU control unit 100 and is used to detect the drive status of the MCU control unit 100 and display it.
[0074] Understandably, the storage control unit 1000 includes low-power double-datarate SDRAM (LPDDR) and embedded memory (Embedded Multi Media Card, eMMC), and is primarily connected to the SOC control unit 200 via an EMI memory interface to meet the RAM & ROM memory operation requirements of the SOC control unit 200. LPDDR4 generally refers to the 4th generation. The display driver unit 900 includes, but is not limited to, RGB LED driver ICs or LEDs, and is primarily connected to the MCU control unit 100 via I2C / GPIO interfaces for driving and displaying product status, etc. The RGB driver adjusts the brightness and color of the LEDs by controlling the current or voltage of the red, green, and blue LEDs.
[0075] The structure also includes a power button 1100; the power button 1100 is connected to the MCU control unit 100 and is used to receive the user's power-on command and control the MCU control unit 100 to power on and off.
[0076] Understandably, the power button 1100 includes PWR_KEY power button and PWR DET power button detection, and is mainly connected to the MCU control unit 100 through the power port and GPIO. It is mainly used for power-on and power-off functions during product use.
[0077] The structure further includes an interface unit; the interface unit connects the charging IC unit 300 and the SOC control unit 200, and is used to charge the battery module unit 400 through the interface, and also to update and debug the SOC control unit 200.

[0079] Specific examples Figure 4As shown, the AR&VR's power-on communication and button / power-off control are as follows: When the device is powered off, it charges by pressing and holding the power button 1100 for 3 to 5 seconds. The charging IC unit 300 charges through the power supply. The MCU control unit 100 detects the power-on command and controls the device to power on. Simultaneously, the MCU controls the SOC control unit 200 to power on, standby, or reset according to the user's needs. When the device is in a high-power state, i.e., the power consumption of the load is not lower than the set power consumption, it enters a dual-system operation state. The MCU control unit 100 and the SOC control unit 200 transmit data and communicate via UART and SPI, including heartbeat packet verification, data interaction, I2S voice transmission, and IO interaction to wake up from sleep. When the user presses and holds the power button for 3 to 5 seconds, the MCU control unit 100 detects the power-off command and shuts down the SOC control unit 200. After the SOC control unit 200 is shut down, the MCU control unit 100 also shuts down, and the device is in a powered-off state.
[0080] In this embodiment, the MCU control unit 100 controls the device to run when the device's power consumption is lower than the set power consumption; when the device's power consumption is high, the MCU control unit 100 sends a start signal to the SOC control unit 200; the SOC control unit 200 starts when it receives the start signal and controls the device to run together with the MCU control unit 100; when the SOC control unit 200 detects that the device is always in a low power consumption state, it enters standby sleep mode.

The button unit 1700 includes, but is not limited to, the camera key, which is primarily connected to the MCU control unit 100 via GPIO for camera taking photos during product use. During normal low-power operation, the MCU control unit 100 and peripherals operate normally according to the usage scenario, while the SOC control unit 200 enters standby mode. When the camera key is triggered during use, the MCU control unit 100 wakes up the SOC control unit 200 via a GPIO interrupt and starts the Camera module 1800.
[0090] Specifically, such as Figure 6The diagram illustrates the power-on, voice chat, and audio / video recording and sharing process for the AR&VR system of this invention. When the device is powered off, it is charged. Simultaneously, the power button 1100 is pressed and held for 5 seconds. The MCU control unit 100 detects the power-on command and controls the device to power on. Simultaneously, the MCU connects to the mobile phone via Bluetooth and controls the SOC control unit 200 to power on. After both systems are enabled, if no wearing action is detected within a preset time (30 seconds) (Hall sensor detects the temples closing), the SOC control unit 200 enters a sleep / standby state. When the Hall sensor detects the temples opening, the MCU control unit 100 enters a standby state. After the touch sensing unit 1400 detects the wearing action, the Bluetooth communication circuit 600, network communication circuit 700, audio acquisition circuit 1200, audio output circuit 1300, light sensing unit 1500, touch sensing unit 1400, position sensing unit 1600, button unit 1700, and drive display unit 900 of the MCU control unit 100 respond. The user can access the voice chat function via the APP or function buttons. The MCU control unit 100 and audio acquisition circuit... When the audio output circuit 1200 and audio output circuit 1300 are activated, the voice chat function is entered. After the user ends the voice chat mode via the APP or button, if no user operation is detected within a preset time (30s), the MCU control unit 100 enters standby mode. When the user starts the audio recording and sharing function via the mobile APP or function button, the MCU control unit 100 wakes up the SOC control unit 200 via GPIO interrupt. The SOC control unit 200 activates the inertial measurement unit 1900 for image stabilization, and the product enters video recording mode. The MCU control unit 100 transmits the audio signal collected by the audio acquisition circuit 1200 to the SOC control unit 200 through the I2S interface for audio synchronization and encoding compression. The SOC control module transmits the audio and video to the mobile phone or network for sharing through the radio frequency Wifi communication circuit 800. During data transmission, if the mobile phone and the MCU control unit 100 are connected and communicating via the Bluetooth communication circuit 600, the PTA port of the Bluetooth communication circuit 600 of the MCU control unit 100 performs data packet traffic arbitration for Wifi and Bluetooth coexistence. The MCU control unit 100 and the SOC control unit 200 transmit data and communicate via UART and SPI (including heartbeat packet verification, data interaction, I2S voice transmission and IO interaction to wake up from sleep). After the user ends the voice and video sharing mode via APP or button, if no user operation is detected within a preset time (30s), the MCU control unit 100 and the SOC control unit 200 will enter standby mode.
