As shown in fig. 1, a schematic flow chart of a power supply adjusting method in an embodiment of the present invention is shown, where the method may include:
acquiring working state information; acquiring the operating state information of the powered electronic equipment;
and adjusting the output voltage of a power supply for supplying power to the electronic equipment based on the working state information.
Specifically, in an embodiment of the present invention, the method may be applied to an electronic device to be powered, that is, the operating state of the electronic device is obtained in real time, and an operating voltage required by the electronic device is determined, so as to control an output voltage of a power supply device serving as a power supply.
The method specifically comprises the following steps: acquiring the working state of the electronic equipment, wherein the electronic equipment is powered;
determining a first voltage required by the electronic equipment to operate based on the acquired working state;
generating and outputting a first instruction for adjusting an output voltage of a power supply based on the determined first voltage.
The electronic device in the embodiment of the present invention may be a device such as a mobile phone or a computer device, but is not limited to the embodiment of the present invention, and any device that can be supplied with power may be used as the electronic device in the embodiment of the present invention.
The electronic device may obtain a working state of the electronic device in real time, where the working state may include at least one of a shutdown state, a startup state, a standby state, a hibernation state, a sleep state, or a normal working state, and each working state may correspond to a voltage value or a voltage range required to maintain the state. That is, after the current operating state of the electronic device is obtained, the voltage value or the voltage range corresponding to the operating state may be correspondingly determined, so that the first instruction for adjusting the output voltage of the power supply device may be correspondingly sent to the power supply device.
Specifically, the processor of the electronic device may monitor, in real time, that the electronic device receives a control instruction, where the control instruction may include a power-on instruction, a power-off instruction, a standby instruction, a hibernation instruction, a sleep instruction, or a control instruction of an operating program, and based on the control instruction, the current operating state of the electronic device may be determined. For example, when a power-on instruction is received, it may be determined that the electronic device is in a power-on state, when a power-off instruction is received, it may be determined that the electronic device is in a state of being ready to be powered off or in a powered off state, and when a hibernation or sleep instruction is received, it may be determined that the electronic device is in a hibernation or sleep state. In addition, the embodiment of the present invention may also determine the current working state by detecting the running program of the electronic device, for example, when it is detected that the electronic device is running a program such as video playback, text editing, or web browsing, or other application programs, it may be determined that the electronic device is in a normal working state, that is, the electronic device is in a state of being operated or used by a user. After the current working state of the electronic device is determined or when the working state of the electronic device is determined to be changed, a first voltage required by the current working state may be further determined, where the first voltage may be a determined voltage value or a voltage range.
In addition, the corresponding relationship between the operating state and the first voltage may be stored in the memory of the electronic device, for example, the corresponding relationship between the operating state and the first power parameter may also be stored, the first power parameter may include the first voltage, and may also include other parameters of power and current, and a person skilled in the art may set the parameter information in the first power parameter according to a requirement, which is not limited herein.
After determining the operating state, the processor of the electronic device may obtain a first voltage corresponding to the operating state according to the correspondence stored in the memory, so that a first instruction for determining output power according to the first voltage may be sent to the power supply device through a connection port connected to the power supply device. The first command sent by the electronic device may include the first voltage, or may also include information about the operating state and the first voltage, and the power supply device may adjust the voltage value of its output power based on the first voltage in the first command, that is, adjust the output power to the first voltage or to a voltage within a range of the first voltage, thereby implementing matching between the supply power and the power required by the electronic device, and having the characteristic of energy saving.
The following illustrates the correspondence relationship between the operating state of the electronic device and the first low voltage in the embodiment of the present invention, but the present invention is not limited thereto.
1) When the system is shut down (S5, ready for shutdown or shutdown state), the required voltage is restored to the minimum voltage of 3V, i.e., the first voltage may be 3V;
2) the system is powered on (S0, power on state), and a first instruction is sent to the power supply device through the power connection port, where the first instruction includes information that the required first voltage is 20V;
3) the system enters an idle mode (or monitor turn off), the first voltage is 12V;
4) the system enters a standby state or S3/S4, determining that the first voltage is 5V;
5) when the electronic device is disconnected from the device when powered, the first voltage is 0V.
Therefore, the electronic equipment can always work under the optimal voltage in different working states, so that the system and the power supply are all in the most appropriate and most energy-saving state, and finally, energy conservation and environmental protection are realized.
In addition, in the embodiment of the present invention, the electronic device may also monitor the current power consumption value of the electronic device in real time, determine a required first voltage according to the power consumption value, and further adjust the power supply device to adjust the output voltage of the output power of the electronic device according to the first voltage.
That is, the processor of the electronic device may monitor the system power consumption in real time, and the system power consumption may be calculated by the difference between the output power and the input power of each electronic device in the electronic device. The processor may correspondingly determine the first voltage corresponding to the current system power consumption after detecting the system power consumption value or when detecting that the amount of change in the system power consumption of the electronic device exceeds a change threshold. The change threshold may be a value preset according to a requirement, and may be a different magnitude in different embodiments, and in addition, a correspondence between system power consumption and a first voltage or a correspondence between system power consumption and a first power parameter may also be stored in the memory, so that the processor may query the first voltage corresponding to the system power consumption value, and generate a first instruction for controlling a voltage value of output power of the power supply device based on the first voltage, thereby implementing matching between the output power of the power supply device and power required by the electronic device.
Based on the configuration, the output voltage of the power supply equipment can be adjusted by the power-supplied electronic equipment based on the working state or system power consumption of the power-supplied electronic equipment, so that the electronic equipment always works under the optimal voltage, the system and the power supply are all in the most appropriate and most energy-saving state, and finally energy conservation and environmental protection are realized.

The method for acquiring the operating state of the electronic device by the power supply device may include: the working state information transmitted by the electronic equipment is received through the power connection port, as described in the above embodiment, the electronic equipment can acquire the working state of the electronic equipment in real time, and when the working state is acquired and the switching of the working state is performed, the current working state can be at least sent to the power supply equipment, and at this time, the power supply equipment can correspondingly adjust the output voltage of the output power of the power supply equipment according to the working state of the electronic equipment.
Similarly, the power supply device in the embodiment of the present invention may also include a memory, where a corresponding relationship between the operating state of the electronic device and the first voltage may be stored in the memory, for example, the corresponding relationship between the operating state and the first power parameter may also be stored, the first power parameter may include the first voltage, and may also include other parameters of power and current, and a person skilled in the art may set parameter information in the first power parameter according to a requirement, which is not limited herein. The power supply device can adjust the voltage value of the output power of the power supply device based on the determined first voltage, namely, the output power is adjusted to the first voltage or adjusted to a voltage within the range of the first voltage, so that the matching of the power supply power and the power required by the electronic device is realized, and the power supply device has the characteristic of energy conservation.
In addition, the method for the power supply device to acquire the operating state of the electronic device may also include:
monitoring the received control instruction;
and acquiring the working state information based on the control instruction.
As described above, the electronic device may monitor the control instruction received by the electronic device in real time, such as a control instruction for turning off, turning on, sleeping, or running a program. For example, when a power-on instruction is received, it may be determined that the electronic device is in a power-on state, when a power-off instruction is received, it may be determined that the electronic device is in a state of being ready to be powered off or in a powered off state, and when a hibernation or sleep instruction is received, it may be determined that the electronic device is in a hibernation or sleep state. That is, the memory of the power supply device may store a corresponding relationship between the control command and the operating state, and determine the operating state according to the received control command, or may directly store a corresponding relationship between the control command and the first voltage, so as to directly determine the required first voltage and correspondingly adjust the voltage of the output power.
In addition, the power supply device may also obtain power consumption information of the electronic device, specifically, the electronic device may also transmit real-time power consumption information thereof to the power supply device, and the power supply device may adjust a voltage value of output power thereof correspondingly based on the power consumption value.
As described in the foregoing embodiment, the electronic device may further monitor a current power consumption value of the electronic device in real time, and transmit the power consumption value to the power supply device through the power connection port, and the power supply device may determine a first voltage required by the electronic device according to the power consumption value, and further adjust an output voltage of the output power of the electronic device according to the first voltage.
Specifically, the memory of the power supply device may further store a corresponding relationship between the power consumption value and the first voltage or the first power parameter, and after receiving the system power consumption value of the electronic device or when detecting that a variation of the system power consumption of the electronic device exceeds a variation threshold, the power supply device may correspondingly determine the first voltage corresponding to the current system power consumption, and output the corresponding output power according to the first voltage, so as to implement matching between the output power of the power supply device and the power required by the electronic device. Wherein the variation threshold can be a preset value according to the requirement, can be a different magnitude in different embodiments,
based on the configuration, the power supply equipment can adjust the output voltage of the power supply equipment based on the working state of the supplied electronic equipment or the system power consumption, so that the electronic equipment always works under an optimal voltage, and the power supply equipment always outputs the most appropriate output power, so that the system and the power supply are all in the most appropriate and most energy-saving states, and finally, energy conservation and environmental protection are realized.

At the same time, the first power connection port 3 may also be used to establish a data connection between the power supply device and the first electronic device, i.e. to perform a data communication connection between the two. For example, the first power connection port 3 in the embodiment of the present invention may include a TYPE C port, or may be another TYPE of interface, and the embodiment of the present invention is not limited.
In addition, the first processor 2 may obtain operating state information of the first electronic device, and adjust the output voltage of the power supply based on the operating state information.
Specifically, the first processor 2 of the first electronic device in the embodiment of the present invention may obtain an operating state of the electronic device, determine a first voltage required for the electronic device to operate based on the obtained operating state, and generate and output a first instruction for adjusting an output voltage of the power supply based on the determined first voltage.
The first processor 2 may obtain its own working state in real time, where the working state may include at least one of a power-off state, a power-on state, an idle state, a standby state, a hibernation state, a sleep state, or a normal working state, and each working state may correspond to a voltage value or a voltage range required to maintain the state. That is, after acquiring the current operating state of the electronic device, the first processor 2 may correspondingly determine the voltage value or the voltage range corresponding to the operating state, so as to correspondingly send the first instruction for adjusting the output voltage of the power supply device to the power supply device.
Specifically, the first processor 2 of the electronic device may monitor, in real time, that the electronic device receives a control instruction, where the control instruction may include a power-on instruction, a power-off instruction, a standby instruction, a hibernation instruction, a sleep instruction, or a control instruction for running a program.

For example, when a power-on instruction is received, it may be determined that the first electronic device is in a power-on state, when a power-off instruction is received, it may be determined that the first electronic device is in a state of being ready to be powered off or in a powered-off state, and when a hibernation or sleep instruction is received, it may be determined that the first electronic device is in a hibernation or sleep state. In addition, the embodiment of the present invention may also determine the current working state by detecting the running program of the electronic device, for example, when it is detected that the first electronic device is running a program such as video playback, text editing, or web browsing, or another application program, it may be determined that the first electronic device is in a normal working state, that is, at this time, the first electronic device is in a state operated or used by a user, or it may be determined that the first electronic device is in an idle state when no application program runs. For example, the first electronic device in the embodiment of the present invention may further include a program monitoring module, where the program monitoring module may monitor an application program currently run by the first electronic device, and the first processor 2 may be connected to the program monitoring module, so as to obtain a currently running program of the first electronic device through the program monitoring module, and further determine the working state.
After determining the current operating state of the first electronic device or when determining that the operating state of the first electronic device changes, the first processor 2 may further determine a first voltage required for the current operating state, where the first voltage may be a certain voltage value or a voltage range.
In addition, the first memory 1 of the first electronic device may store a corresponding relationship between the operating state and the first voltage, or may store a corresponding relationship between the operating state and the first power parameter, where the first power parameter may include the first voltage, and may also include other parameters of power and current, and a person skilled in the art may set parameter information in the first power parameter according to a requirement, which is not limited herein.
After determining the operating state or switching the operating state of the first electronic device, the first processor 2 of the first electronic device may obtain a first voltage corresponding to the operating state according to the correspondence stored in the first memory 1, so that a first instruction for determining output power according to the first voltage may be sent to the power supply device through the first power connection port connected to the power supply device. The first instruction sent by the first electronic device may include the first voltage, or may also include information of the operating state and the first voltage, and the power supply device may adjust the voltage value of the output power thereof based on the first voltage in the first instruction, that is, adjust the output power to the first voltage or to a voltage within a range of the first voltage, thereby implementing matching between the power supply power and the power required by the electronic device, and having the characteristic of energy saving.
