The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0044] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on virtual reality devices and may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.

[0045] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a power supply control program.

[0046] exist Figure 1 In the virtual reality device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 can be set in the virtual reality device. The virtual reality device calls the power supply control program stored in the memory 1005 through the processor 1001 and executes the power supply control method provided in the embodiment of the present invention.

[0047] This invention provides a power supply control method applied to a virtual reality device, wherein the virtual reality device is equipped with at least one camera module. Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the power supply control method of the present invention.

[0048] In this embodiment, the power supply control method includes the following steps:

[0049] Step S10: Monitor the current working mode of the camera module.

[0050] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, or an electronic device, control device, virtual reality device, etc., capable of realizing the above functions. The following uses a virtual reality device as an example to illustrate this embodiment and the subsequent embodiments.

[0051] It is understood that the camera module can be a module set on the virtual reality device to achieve certain functions through cameras. The functions achieved by the camera module include, but are not limited to, eye tracking, depth tracking, and see-through functions. The number of camera modules is at least one, and can be determined according to the specific scenario. For example, the number of camera modules can be 6, 7, 10, or other numbers. This embodiment does not impose any restrictions here. The current working mode can be the working mode of the camera module that is turned on in the virtual reality device. The current working mode includes, but is not limited to, high power consumption mode, low power consumption mode, and normal power consumption mode.

[0052] Step S20: Determine the target power supply mode of the low dropout regulator referenced by the camera module based on the current operating mode.

[0053] It is understood that the low dropout regulator (LDO) can be a voltage regulator provided by the PMIC to power the camera module; after the camera module is turned on, the PMIC powers the operating camera module through the LDO; the low dropout regulator referenced by the camera module can be a low dropout regulator that powers the camera module; the number of low dropout regulators referenced by each camera module can be determined according to the specific scenario, and the number of regulators referenced by the camera module includes, but is not limited to, two, three or other numbers, which is not limited in this embodiment; the target power supply mode can be a power supply mode adapted to the current operating mode of the camera module, and the target power supply mode can be dynamically adjusted according to the current operating mode of the camera module.

[0054] Step S30: Adjust the power supply mode of the low dropout regulator to the target power supply mode to power the camera module.

[0055] In practice, the virtual reality device monitors the current operating mode of the activated camera module, determines the target power supply mode of the low-dropout regulator that powers the camera module based on the current operating mode, and adjusts the power supply mode of the low-dropout regulator to the target power supply mode, so as to control the low-dropout regulator to power the camera module in a target power supply mode that is compatible with the current operating mode of the camera module.

[0056] Furthermore, in order to dynamically adjust the power supply mode of the low-dropout regulator so that the power supply mode is adapted to the working mode of the camera module, step S10 includes: monitoring the working parameters of the low-dropout regulator provided by the power management integrated circuit through a monitoring thread; and determining the current working mode of the camera module based on the working parameters.

[0057] It is understandable that the monitoring thread can be a thread that monitors the operating parameters of the low-dropout regulator provided by the power management integrated circuit. The monitoring thread can be established in the kernel to monitor the operating parameters of the low-dropout regulator, including but not limited to the usage count and path current of the low-dropout regulator; the current operating mode of the camera module is determined based on the usage count and path current of the low-dropout regulator.

[0058] In practice, the usage count and path current of the low-dropout regulator provided by the power management integrated circuit are monitored by the monitoring thread. The current working mode of the camera module is determined based on the usage count and path current. The target power supply mode of the low-dropout regulator referenced by the camera module is determined based on the current working mode, and the power supply mode of the low-dropout regulator is adjusted to the target power supply mode to power the camera module.

[0059] Furthermore, to improve the accuracy of monitoring the operating parameters of the low-dropout regulator, the operating parameters include usage count and path current; the monitoring of the operating parameters of the low-dropout regulator provided by the power management integrated circuit through the monitoring thread includes: monitoring the reference information of the low-dropout regulator provided by the power management integrated circuit by the camera module through the monitoring thread, and determining the usage count of the low-dropout regulator based on the reference information; and monitoring the path voltage difference of the path where the low-dropout regulator is located through the monitoring thread, and determining the path current of the low-dropout regulator based on the path voltage difference.

[0060] It is understandable that the usage count can be the count of the low-dropout regulator referenced by the camera module; the path current can be the current in the path where the low-dropout regulator is located; the reference information can be the information of whether the low-dropout regulator is referenced or released by the camera module; determining the usage count of the low-dropout regulator based on the reference information can be based on determining whether the low-dropout regulator is referenced or released, and determining the usage count based on the information of the low-dropout regulator being referenced and released.

[0061] It should be understood that the path of the low dropout regulator is equipped with a monitoring resistor. By obtaining the voltage across the monitoring resistor, the path voltage difference of the low dropout regulator can be determined. Based on the path voltage difference and the resistance value of the monitoring resistor, the path current of the low dropout regulator can be determined.

[0062] It should be noted that when a camera module is activated, its corresponding low-dropout regulator is used, and the count is incremented by one. If the low-dropout regulator is deactivated, the count is decremented by one. Therefore, the number of camera modules activated can be determined by the usage count of the low-dropout regulator.

[0063] In practical implementation, for example, PMIC provides four LDOs: LDO1, LDO2, LDO3, and LDO4. The virtual reality device is equipped with six camera modules: Camera1, Camera2, Camera3, Camera4, Camera5, and Camera6. Camera1 corresponds to LDO1 and LDO2, Camera2 corresponds to LDO2 and LDO3, Camera3 corresponds to LDO3 and LDO4, Camera4 corresponds to LDO1 and LDO3, and Camera5 corresponds to LDO4. Camera1 corresponds to LDO4, and Camera6 corresponds to LDO3 and LDO4. During the operation of the virtual reality device, assuming that Camera1, Camera4, and Camera5 are invoked, the usage count of LDO1 monitored by the monitoring thread is 3, the usage count of LDO2 is 1, the usage count of LDO3 is 1, and the usage count of LDO4 is 1. The voltage difference of each path is obtained by setting the monitoring resistors in the paths where LDO1, LDO2, LDO3, and LDO4 are located, and the path current of the corresponding path is determined according to the voltage difference of each path and the resistance value of the corresponding monitoring resistor.

[0064] Furthermore, to improve the accuracy of power supply mode adjustment, determining the current operating mode of the camera module based on the operating parameters includes: determining the current operating mode of the camera module as a high-power-consumption operating mode when the usage count is greater than a preset count threshold and the path current is greater than a preset current threshold; and determining the current operating mode of the camera module as a low-power-consumption operating mode when the usage count is less than the preset count threshold and / or the path current is less than the preset current threshold.

[0065] It is understandable that the preset counting threshold can be a pre-set counting threshold used to determine whether the camera module is in a high power consumption working mode; the preset current threshold can be a pre-set current threshold used to determine whether the camera module is in a high power consumption working mode; a high power consumption working mode can be a working mode with high power consumption; and a low power consumption working mode can be a working mode with low power consumption.

[0066] This embodiment proposes a power supply control method for a virtual reality device. The virtual reality device is equipped with at least one camera module. The method monitors the current operating mode of the camera module; determines the target power supply mode of the low-dropout voltage regulator (LDV regulator) used by the camera module based on the current operating mode; and adjusts the power supply mode of the LTV regulator to the target power supply mode to power the camera module. This embodiment determines the target power supply mode of the LTV regulator used by the camera module by monitoring its current operating mode and adjusts the LTV regulator's power supply mode to the target power supply mode to power the camera module. This allows for dynamic adjustment of the LTV regulator's power supply mode according to the camera module's operating mode, ensuring that the LTV regulator's power supply mode adapts to the camera module's operating mode, thereby reducing overall power consumption and improving system stability.

[0067] refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the power supply control method of the present invention.

[0068] Based on the first embodiment described above, in this embodiment, step S20 includes:

[0069] Step S201: When the current working mode is a high power consumption working mode, determine that the target power supply mode of the low dropout voltage regulator referenced by the camera module is a normal power supply mode.

[0070] Understandably, a normal power supply mode can be a power supply mode that can output a higher current. If the current working mode of the camera module is a high power consumption mode, it is determined that the current demand of the camera module is high. Therefore, the target power supply mode of the corresponding low dropout regulator is determined to be the normal power supply mode to output the current that meets the needs of the camera module, thereby improving system stability. The high power consumption mode of the camera module corresponds to the normal power supply mode of the low dropout regulator.

[0071] Step S201': When the current working mode is a low power consumption working mode, determine that the target power supply mode of the low dropout regulator referenced by the camera module is a low power consumption power supply mode.

[0072] Understandably, a low-power power supply mode can be a power supply mode that can output a lower current. If the current working mode of the camera module is a low-power working mode, it is determined that the current requirement of the camera module is low. Therefore, the target power supply mode of the corresponding low-dropout regulator is determined to be a low-power power supply mode, which can reduce the power consumption of the whole machine while meeting the current requirement of the camera module. The low-power working mode of the camera module corresponds to the low-power power supply mode of the low-dropout regulator.

[0073] In this embodiment, when the current operating mode is a high-power consumption mode, the target power supply mode for the low-dropout regulator used by the camera module is determined to be the normal power supply mode; when the current operating mode is a low-power consumption mode, the target power supply mode for the low-dropout regulator used by the camera module is determined to be the low-power supply mode. This allows the low-dropout regulator to output current sufficient for the camera module's current requirements through the normal power supply mode, thereby improving system stability. Conversely, when the camera module's current requirements are low, the corresponding low-dropout regulator's power supply mode is determined to be the low-power supply mode, thereby reducing overall power consumption. This approach improves system stability while simultaneously reducing overall power consumption.

[0074] refer to Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the power supply control method of the present invention.

[0075] Based on the above embodiments, in this embodiment, step S30 includes:

[0076] Step S301: Obtain the power supply voltage range of the low dropout regulator and the required voltage range of the camera module.

[0077] It is understandable that the power supply voltage range can be the voltage range that the low dropout regulator can output; the required voltage range can be the range of power supply voltage required by the camera module.

[0078] Step S302: Determine the voltage adjustment range based on the supply voltage range and the required voltage range.

[0079] It is understandable that the voltage adjustment range can be an area where the supply voltage range and the demand voltage range overlap.

[0080] Step S303: Adjust the power supply voltage of the low dropout regulator within the voltage adjustment range, and adjust the power supply mode of the low dropout regulator to the target power supply mode to power the camera module.

[0081] It is understandable that the power supply voltage of the low-dropout regulator is adjusted within the voltage adjustment range according to the voltage requirements of the camera module.

[0082] In practical implementation, for example: the usage count of LDOs is represented by RefCount, with a preset counting threshold of 'a'. The virtual reality device monitors the referencing and releasing status of LDOs provided by the PMIC by the camera module through a monitoring thread, and determines the usage count of each LDO based on the referencing and releasing status. It determines the path voltage difference by monitoring the voltage difference across the monitoring resistors set in the path where each LDO is located, and determines the path current based on the path voltage difference and the resistance value of the corresponding monitoring resistor. Assuming the usage count RefCount-k of LDO-k is greater than 'a', and the path current Ik is greater than the preset current threshold, then the current operating mode of the camera module is determined to be a high-power consumption operating mode. At this time, the target power supply mode of LDO-k is determined to be the normal power supply mode, and the power supply mode of LDO-k is adjusted to the normal power supply mode to increase the output current, thereby meeting the needs of the camera module. Within the voltage adjustment range, the power supply voltage is increased according to the required voltage of the camera module. If the usage count RefCount-k of LDO-k is detected... If Count-k is less than a, and / or the path current Ik is less than the preset current threshold, then the power supply mode of LDO-k will be adjusted to low power supply mode to reduce the output current, thereby reducing the overall power consumption, and the power supply voltage will be reduced within the voltage adjustment range according to the voltage requirements of the camera module.

[0083] Furthermore, in order to improve the accuracy of voltage regulation, step S303 includes: obtaining a preset voltage adjustment step size; adjusting the power supply voltage of the low dropout regulator according to the preset voltage adjustment step size within the voltage adjustment range, and adjusting the power supply mode of the low dropout regulator to the target power supply mode to power the camera module.

[0084] It is understandable that the voltage adjustment step size can be a pre-adjusted step size for adjusting the output voltage of the low-dropout regulator.

[0085] In specific implementations, for example: the voltage adjustment range is (2.75V, 3.2V), and the voltage adjustment step size is 20mV. Assuming the target power supply mode of the low-dropout regulator is the normal power supply mode, within the range of (2.75V, 3.2V), the power supply voltage of the low-dropout regulator is increased in 20mV steps according to the voltage requirement of the camera module, and the power supply mode of the low-dropout regulator is adjusted to the normal power supply mode to provide higher current to the camera module and improve system stability. Assuming the target power supply mode of the low-dropout regulator is the low-power power supply mode, within the range of (2.75V, 3.2V), the power supply voltage of the low-dropout regulator is decreased in 20mV steps according to the voltage requirement of the camera module, and the power supply mode of the low-dropout regulator is adjusted to the low-power power supply mode to reduce the overall power consumption. The voltage adjustment range and voltage adjustment step size can be set to other values ​​according to the specific scenario, and this embodiment does not impose any restrictions.

[0086] This embodiment obtains the supply voltage range of the low-dropout regulator and the required voltage range of the camera module; determines a voltage adjustment range based on the supply voltage range and the required voltage range; adjusts the supply voltage of the low-dropout regulator within the voltage adjustment range, and adjusts the power supply mode of the low-dropout regulator to the target power supply mode to power the camera module. This embodiment adjusts the supply voltage of the low-dropout regulator within the voltage adjustment range determined by the supply voltage range and the required voltage range, and adjusts the power supply mode of the low-dropout regulator to the target power supply mode to power the camera module. This allows for dynamic adjustment of the supply voltage and power supply mode of the low-dropout regulator, improving system stability while reducing overall power consumption.

[0087] Furthermore, embodiments of the present invention also propose a storage medium storing a power supply control program, which, when executed by a processor, implements the steps of the power supply control method described above.
