The electronic equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.
The execution main body of the voltage control method provided in the embodiment of the present invention may be the electronic device, or may also be a functional module and/or a functional entity capable of implementing the voltage control method in the electronic device, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited. The following takes an electronic device as an example to exemplarily explain a voltage control method provided by an embodiment of the present invention.
The voltage control method provided by the embodiment of the invention can be executed under the condition that a user uses the electronic equipment, for example, under the condition that the user plays games through the electronic equipment.
Generally, in order to ensure the service life and the operation reliability of the electronic device, the clock frequency of the electronic device in the current operation is generally lower than the maximum clock frequency of the electronic device, that is, the clock frequency of the electronic device in the operation is generally lower than the maximum clock frequency of the electronic device.
However, as more and more users play games at present and the requirements of the users on the hardware performance of the electronic device are higher and higher, that is, the users may demand the electronic device to have a higher operation speed, in order to meet the increasing requirements of the users on the operation speed of the electronic device, the embodiment of the invention may increase the operation speed of the electronic device according to the actual requirements of the users. The operation speed of the electronic equipment depends on the clock frequency of the electronic equipment, namely, the operation speed of the electronic equipment can be increased by increasing the clock frequency of the electronic equipment, so that the operation speed of the electronic equipment can be increased by increasing the clock frequency of the electronic equipment. Specifically, the embodiment of the invention can improve the clock frequency of the electronic equipment by improving the working voltage of the electronic equipment, thereby improving the running speed of the electronic equipment. Namely, the embodiment of the invention can improve the operation speed of the electronic equipment finally by improving the voltage of the electronic equipment.
The clock frequency of the electronic device generally refers to a dominant frequency of a Central Processing Unit (CPU) of the electronic device, that is, a clock frequency of the CPU during operation; generally, the higher the main frequency of the CPU, the faster the operation speed of the CPU, that is, the higher the operation speed of the electronic device.
In the embodiment of the present invention, in a process that a user (for example, a target user in the embodiment of the present invention) plays a game through an electronic device, the electronic device may dynamically adjust a working voltage of the electronic device according to a parameter that can reflect a use requirement of the target user, so as to dynamically adjust an operation speed of the electronic device, so that the operation speed of the electronic device may adapt to the use requirement of the target user. Specifically, the electronic device may obtain a parameter related to the target user (e.g., a heart rate of the target user operating the electronic device and/or an operating frequency of the target user on the electronic device), and adjust an operating voltage of the electronic device according to the parameter. Therefore, the electronic device can adjust the working voltage of the electronic device in real time according to the parameters related to the target user, and can control the running speed of the electronic device in real time, so that the running speed of the electronic device can adapt to the use requirements of the target user. Therefore, the situation that the electronic equipment is overheated due to the fact that the electronic equipment continuously works at a high voltage can be effectively prevented on the basis of controlling the running speed of the electronic equipment, and therefore the running stability of the electronic equipment can be improved on the basis of not reducing the service life of the electronic equipment.
The voltage control method provided by the embodiment of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a voltage control method, which may include steps 201 and 202 described below.
Step 201, the electronic device obtains a first parameter.
Wherein the first parameter may include at least one of: the heart rate of a target user operating the electronic device, and the operating frequency of the target user operating the electronic device.
Optionally, in the embodiment of the present invention, the electronic device may obtain the heart rate of the target user through at least one heart rate detection module disposed on the electronic device. For example, this at least one heart rate detection module can be at least one heart rate sensor, and electronic equipment can acquire target user's heart rate through at least one heart rate sensor who sets up on electronic equipment promptly.
Optionally, in the embodiment of the present invention, a setting position of the at least one heart rate detection module on the electronic device may be any position of the electronic device that the hand of the target user may contact for a long time when the target user holds the electronic device, so that the hand of the target user holding the electronic device can contact with the at least one heart rate detection module provided on the electronic device for a long time. Therefore, the accuracy of the electronic equipment for acquiring the heart rate of the target user can be improved.
For example, the setting position may be any position on the frame of the electronic device, or the setting position may be any position on the rear cover of the electronic device. Promptly above-mentioned at least one rhythm of the heart detection module can set up the optional position on the electronic equipment frame, perhaps, this at least one rhythm of the heart detection module can set up the optional position of covering behind electronic equipment. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in an embodiment of the present invention, the at least one heart rate detection module may acquire the heart rate of the target user by using a photoelectric measurement method (also referred to as a photoplethysmography).
Specifically, every heart rate detection module in above-mentioned at least one heart rate detection module can include: a light source and a detector. Wherein, the light source can emit light capable of irradiating subcutaneous capillaries of a human body; this detector can be according to the reverberation from human subcutaneous reverberation to the detector, periodically gather the image of target user subcutaneous (in the target user holds electronic equipment's the hand, and with the subcutaneous of the part that this heart rate detection module contacted), then, electronic equipment can handle the image that this detector gathered to acquire target user's heart rate.
It can be understood that the foregoing photoelectric measurement method is only an exemplary illustration of a method for acquiring a heart rate of a target user, and does not limit any embodiment of the present invention, and in an actual implementation, any other possible heart rate measurement method may also be adopted to acquire a heart rate of a target user in the embodiment of the present invention, which may specifically be determined according to actual usage requirements, and the embodiment of the present invention is not limited.
Optionally, in this embodiment of the present invention, the electronic device may periodically acquire the first parameter. For example, the electronic device may periodically acquire the first parameter with 5 seconds (S) as one acquisition period.
Step 202, the electronic device adjusts the working voltage of the electronic device according to the first parameter.
In the embodiment of the present invention, the electronic device may adjust the operating voltage of the electronic device to the rated operating voltage of the electronic device according to the first parameter, or adjust the operating voltage of the electronic device to be higher than the rated operating voltage of the electronic device. Namely, in the embodiment of the invention, the electronic equipment can take the rated working voltage of the electronic equipment as a reference, and improve the working voltage of the electronic equipment according to the first parameter; the operating voltage of the electronic equipment is increased, so that the operating speed of the electronic equipment can be increased, the situation that the electronic equipment is overheated due to the fact that the electronic equipment continuously operates at a high voltage can be effectively prevented on the basis of controlling the operating speed of the electronic equipment, and the operating stability of the electronic equipment can be improved on the basis of not reducing the service life of the electronic equipment.
In practical implementation, there may be a case where the electronic device adjusts the current operating voltage of the electronic device to be lower according to the first parameter. It is understood that this situation means that the operating voltage of the electronic device before adjustment is higher than the operating voltage of the electronic device after adjustment.
Optionally, in the embodiment of the present invention, a battery for providing a working voltage for the electronic device is disposed in the electronic device, and the battery may be a rechargeable battery. For example, nickel cadmium batteries, lithium polymer batteries, nickel metal hydride batteries, lithium batteries, and the like can be used.
When the electronic device is not connected with an external power supply, the electronic device can be powered by a battery built in the electronic device. In another possible implementation manner, when the electronic device is connected to an external power source, the electronic device may be powered by a battery built in the electronic device. In yet another possible implementation, when the electronic device is connected to an external power source, the electronic device may be directly powered by the external power source.
In the following, an exemplary method for adjusting the operating voltage of the electronic device according to the first parameter in the three possible implementation manners is described.
Optionally, in an embodiment of the present invention, in the possible implementation manner, the electronic device may adjust the operating voltage of the electronic device by adjusting the discharge power of a battery built in the electronic device according to the first parameter; in another possible implementation manner, the electronic device may adjust a current charging power of the electronic device according to the first parameter, and adjust a discharging power of the battery according to the adjusted charging power to adjust an operating voltage of the electronic device; in yet another possible implementation manner, the electronic device may adjust the current charging power of the electronic device according to the first parameter, (in this case, the operating power of the electronic device may be a part of or all of the current charging power of the electronic device), so as to adjust the operating voltage of the electronic device.
Further, in one possible implementation manner, since the storable electric energy of the battery built in the electronic device is constant, the remaining electric energy of the battery decreases and the outputtable power of the battery decreases as the discharging time of the battery increases. If the resistance value (i.e. the load resistance) of the electronic device remains unchanged, the output voltage of the battery gradually decreases as the output power of the battery decreases; in practical implementation, the electronic device generates heat during operation, so that the resistance of the electronic device is increased, that is, the output voltage of the battery is further reduced. In this way, in a case where the battery cannot provide sufficient output power for the electronic device, that is, the discharge power of the battery is small, the electronic device may not adjust the discharge power of the battery, so that the operating voltage of the electronic device cannot be adjusted.
It will be appreciated that in one possible implementation, as the output power of the battery is reduced, even if the electronic device increases the operating voltage of the electronic device above the rated operating voltage, the time during which the electronic device continues to operate at that voltage is relatively short, i.e., the electronic device may quickly drop below the rated operating voltage.
In another possible implementation manner and yet another possible implementation manner, the electronic device may first adjust a current charging power (for example, a target charging power described below) of the electronic device according to the first parameter, and then adjust an operating voltage of the electronic device according to the adjusted target charging power. The method for adjusting the current charging power of the electronic device according to the first parameter and the method for adjusting the operating voltage of the electronic device according to the adjusted charging power by the electronic device will be specifically described in the following embodiments, which are not repeated herein.
Optionally, in the embodiment of the present invention, the electronic device may adjust the operating voltage of the electronic device through a power management system of the electronic device according to the first parameter.
Illustratively, fig. 2 shows a hardware schematic diagram of a power management system 300 of an electronic device according to an embodiment of the present invention. As shown in fig. 2, the power Management System 300 may include a charge pump 310, a Battery 320, a power Management chip 330, and a Battery Management chip 340 (BMS). The charge pump 310 is respectively connected with the battery 320, the power management chip 330 and the CPU of the electronic device; the battery 320 is respectively connected with the power management chip 330, the battery management chip 340 and the electronic device; the power management chip 330 is connected to the battery management chip 340.
The charge pump 310, also referred to as a switched capacitor or voltage converter, may be used for voltage conversion (boosting or stepping down) of the input voltage.
The battery 320 may be used to provide an operating voltage for the electronic device.
The battery management chip 340 may be used to obtain the remaining power of the battery 320.
The power management chip 330 may be configured to adjust an output power of the charge pump 310 according to the first parameter, that is, adjust a charging power of the electronic device; the discharging power of the battery 320 can also be adjusted according to the remaining power and the first parameter obtained by the battery management chip 340; can also be used to control the connection state (on and off) of the charge pump 310 and the battery 320; and also for controlling the connection state (on and off) of the battery 320 to the CPU of the electronic device.
It can be understood that, in the embodiment of the present invention, in one possible implementation manner described above, the power management chip 330 may, when the obtained remaining power of the battery 320 meets a discharging requirement (for example, the outputtable power of the battery 320 is greater than a preset power threshold), increase the discharging power of the battery 320 (specifically, increase the discharging power of the battery 320 by increasing the discharging voltage of the battery 320) according to the first parameter, so as to increase the operating voltage of the electronic device. In another possible implementation manner, the power management chip 330 controls the charge pump 310 to be connected to the battery 320, controls the battery 320 to be connected to a CPU of the electronic device, controls the charge pump 310 to be disconnected from the CPU of the electronic device, and controls the output power of the charge pump 310 and the discharge power of the battery 320 according to the first parameter to increase the operating voltage of the electronic device; in yet another possible implementation manner, the power management chip 330 controls the charge pump 310 to be conducted with the battery 320, controls the charge pump 310 to be conducted with a CPU of the electronic device, and controls the output power of the charge pump 310 according to the first parameter to increase the operating voltage of the electronic device.
It will be appreciated that the charge pump is essentially a switch, the principle of which is to charge a capacitor with an input voltage and then use the charged capacitor as a power source to power a load.
In the voltage control method provided by the embodiment of the invention, because parameters related to the target user, such as the heart rate of the target user operating the electronic device, the operating frequency of the target user operating the electronic device, and the like, can be used for reflecting the use requirement of the target user on the electronic device, the electronic device can adjust the working voltage of the electronic device in real time according to the parameters related to the target user, and can control the running speed of the electronic device in real time, so that the running speed of the electronic device can adapt to the use requirement of the target user in real time. Therefore, the situation that the electronic equipment is overheated due to the fact that the electronic equipment continuously works at a high voltage can be effectively prevented on the basis of controlling the running speed of the electronic equipment, and therefore the running stability of the electronic equipment can be improved on the basis of not reducing the service life of the electronic equipment.
Optionally, in this embodiment of the present invention, in another possible implementation manner and the yet another possible implementation manner, the step 202 may be specifically implemented by a step 202a and a step 202b described below.
Step 202a, the electronic device adjusts the target charging power according to the first parameter.
The target charging power may be a current charging power of the electronic device.
Optionally, in an embodiment of the present invention, in another possible implementation manner described above, the target charging power is a charging power of a battery built in the electronic device. In yet another possible implementation manner, the target charging power may include a first power and a second power, where the first power may be a charging power of a battery built in the electronic device, and the second power may be an operating power of the electronic device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
It is to be understood that when the target charging power is changed (increased or decreased), at least one of the first power and the second power is also changed.
Optionally, in this embodiment of the present invention, when the target charging power is changed, the first power and the second power may be distributed according to a preset ratio. For example, the distribution ratio of the first power and the second power may be 1:1, or 1:2, or 2:1, etc.; the first power is only required to be less than or equal to the maximum charging power of the battery, and the second power is only required to be less than or equal to the maximum working power of the electronic equipment. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the present invention, the current charging power (i.e., the target charging power) of the electronic device may be greater than or equal to the rated charging power of the electronic device and less than or equal to the maximum charging power of the electronic device.
Further, in the embodiment of the present invention, after the electronic device adjusts the target charging power according to the first parameter, the adjusted target charging power may also be greater than or equal to a rated charging power of the electronic device and less than or equal to a maximum charging power of the electronic device.
In addition, it should be noted that, in practical implementation, in order to ensure the service life of the battery (i.e. to avoid the internal structure of the battery from being damaged during the charging process), the charging process of the battery may be divided into a plurality of charging stages.
For example, the battery built in the electronic device is a lithium battery, as shown in table 1 below, the charging process of the lithium battery may be divided into five stages, which are: the charging method comprises a pre-charging stage, a low-current constant-current charging stage, a large-current constant-voltage charging stage and a low-current constant-voltage charging stage. Specifically, in the pre-charging stage, the voltage range of two ends of the battery (namely the positive pole of the battery and the negative pole of the battery) is 2V-3V; in the stage of low-current constant-current charging, the voltage range of two ends of the battery (namely the anode of the battery and the cathode of the battery) is 3V-3.5V; in the large-current constant-current charging stage, the voltage range of two ends of the battery (namely the anode of the battery and the cathode of the battery) is 3.5V-4.35V; in the large-current constant-voltage charging stage, the voltage range of two ends of the battery (namely the positive electrode of the battery and the negative electrode of the battery) is 4.35V-4.4V; during the low current constant voltage charging phase, the voltage across the battery (i.e., the positive electrode of the battery and the negative electrode of the battery) was 4.4V.
TABLE 1
Figure GDA0002950647890000071
As can be seen from table 1, in an actual implementation, the power management system may include a first charging chip, a second charging chip, and a third charging chip. For example, a first charging chip may be bq2589x, a second charging chip may be bq25970 (i.e., a charge pump), and a third charging chip may be bq 25890. Specifically, as shown in table 1, in the pre-charge stage and the large current constant current charge stage, the electronic device may use the first charging chip to charge the battery, and at this time, the power management chip and the battery management chip are not needed to monitor the electric quantity of the battery in real time. In the large-current constant-current charging stage and the large-current constant-voltage charging stage, the electronic device may use the second charging chip to charge the battery, and at this time, the power management chip and the battery management chip are required to monitor the electric quantity of the battery so as to control the voltage at the two ends of the battery (i.e., the voltage between the positive electrode of the battery and the negative electrode of the battery). In the low-current constant-voltage charging stage, the electronic equipment can charge the battery by adopting the third charging chip, the charging current of the battery in the stage can be reduced from 2A to cut-off current, and at the moment, the real-time monitoring on the electric quantity of the battery by the power management chip and the battery management chip is not needed.
It should be noted that, in another possible implementation manner and yet another possible implementation manner, in theory, the electronic device may adjust the charging power of the battery through the first parameter at each charging stage of the battery. In practical implementation, however, in order to prevent the battery from being damaged, the electronic device may adjust the charging power of the battery according to the first parameter during the high-current constant-current charging stage and the high-current constant-voltage charging stage.
Optionally, in the embodiment of the present invention, after the electronic device acquires the first parameter, the first parameter may be compared with a first target threshold and a second target threshold, where the electronic device acquires the first parameter, specifically, a parameter value of the first parameter may be acquired, for example, the electronic device acquires a heart rate of a target user who operates the electronic device, specifically, a numerical value of the heart rate of the target user who operates the electronic device may be acquired by the electronic device, and the electronic device acquires an operating frequency of the electronic device that the target user operates, specifically, a numerical value of the operating frequency of the electronic device that the target user operates the electronic device may be acquired by the electronic device. As such, the electronic device comparing the first parameter to the first target threshold and the second target threshold may be understood as the electronic device comparing the parameter value of the first parameter to the first target threshold and the second target threshold. For convenience of description, the first parameter is used as a parameter value of the first parameter (in this document, the parameter and the parameter value refer to a specific value, and they are interchangeable, for example, the heart rate refers to a heart rate value, and the operating frequency refers to an operating frequency value).
In the embodiment of the present invention, if the first parameter is smaller than the first target threshold, the electronic device may keep the target charging power unchanged; if the first parameter is greater than or equal to the first target threshold and less than or equal to the second target threshold, the electronic device may obtain a first power adjustment amount according to the first parameter, and adjust the target charging power according to the first power adjustment amount; if the first parameter is greater than the second target threshold, the electronic device may adjust the target charging power to a maximum charging power of the electronic device. Wherein the first target threshold is smaller than the second target threshold.
Optionally, in this embodiment of the present invention, the first target threshold and the second target threshold may be reference values that are pre-stored in the electronic device, or the first target threshold and the second target threshold may be reference values that are determined by the electronic device according to a first parameter acquired within a preset time period.
It is to be understood that, when the first target threshold and the second target threshold are reference values determined by the electronic device according to the first parameter acquired within the preset time period, the electronic device may determine the first target threshold and the second target threshold before executing the above S201, that is, acquiring the first parameter.
Wherein the first target threshold may include a first threshold corresponding to a heart rate of the target user and a second threshold corresponding to an operating frequency of the target user to operate the electronic device. The second target threshold may include a third threshold corresponding to a heart rate of the target user and a fourth threshold corresponding to an operating frequency at which the target user operates the electronic device.
The method for determining the first target threshold and the second target threshold by the electronic device is described in detail below.
1) The electronic device determines a first threshold a1 and a third threshold a 2.
It is assumed that the preset time period includes a first time period and a second time period. The electronic device may obtain an average heart rate a of the target user over a first time period, and then the electronic device may continue to obtain the heart rate of the target user over a second time period, and if a duration of the heart rate of the target user being less than or equal to 0.85a is greater than or equal to the first duration within the second time period, the electronic device may determine that the first threshold a1 is 0.8 a; if the heart rate of the target user is greater than 0.85a and the duration less than 0.95a is greater than or equal to the first duration within the second time period, the electronic device may determine that the first threshold a1 is 0.9 a; if the duration of the target user's heart rate being greater than or equal to 0.95a is greater than or equal to the first duration within the second time period, the electronic device may determine that the first threshold a1 is a.
It will be appreciated that the first threshold a1 described above may be used as the reference heart rate for the target user.
Optionally, in an embodiment of the present invention, the third threshold a2 may be determined according to the first threshold a 1. For example, the third threshold a2 may be a x a1, and a is a number greater than 1.
2) The electronic device determines a second threshold F1 and a fourth threshold F2.
Assuming that the preset time period includes a third time period, the electronic device may obtain the number of times of operations of the target user on the electronic device in the third time period, thereby determining an average operating frequency of the target user in the third time period, and determining the average operating frequency as the second threshold F1.
Further, the third time period may be a time period when the electronic device detects that the target user operates on the electronic device. Assuming that the third time period is {0, T }, if the electronic device does not detect the operation of the target user within a certain time period T1 from the starting time point 0 of the third time period, that is, the electronic device detects the operation of the target user at the time point T1, the electronic device may adjust the third time period to be { T1, T + T1}, that is, the electronic device may adjust the starting time point of the third time period to be T1.
It is understood that the second threshold F1 can be used as a reference operation frequency for the target user to operate the electronic device.
Further, the electronic device may determine the fourth threshold F2 according to the second threshold F1. For example, the fourth threshold F2 may be b × F1 and is a value greater than 1.
Optionally, in the embodiment of the present invention, the step 202a may be specifically implemented by the following step 202a1, step 202a2, or step 202a 3.
In step 202a1, in case the first parameter is smaller than the first target threshold, the electronic device keeps the target charging power unchanged.
Step 202a2, when the first parameter is greater than the first target threshold and smaller than the second target threshold, the electronic device obtains a first power adjustment amount according to the first parameter, and adjusts the target charging power according to the first power adjustment amount.
In step 202a3, when the first parameter is greater than the second target threshold, the electronic device adjusts the target charging power to the maximum charging power of the electronic device.
In the embodiment of the present invention, in step 202a2, the first power adjustment amount is an adjustment amount with respect to a rated charging power of the electronic device.
For example, if the rated charging power of the electronic device is P and the first power adjustment amount is Δ P, the charging power (i.e., the adjusted target charging power) of the electronic device adjusted according to the first power adjustment amount Δ P is P + Δ P.
In the embodiment of the present invention, the electronic device may determine the manner of adjusting the target charging power of the electronic device according to different first parameters (specifically, different parameter values of the first parameters), so that flexibility and reliability of adjusting the target charging power of the electronic device may be improved.
Optionally, in this embodiment of the present invention, in the step 202a2, the method for adjusting the target charging power by the electronic device according to the first power adjustment amount specifically includes: and the electronic equipment adjusts the target charging power according to the first power adjustment amount, the target charging power and the rated charging power of the electronic equipment.
It should be noted that, in an actual implementation, the current charging power (i.e., the target charging power) of the electronic device may be different from the rated charging power of the electronic device, and then, after the electronic device obtains the first power adjustment amount, the electronic device needs to obtain the current charging power (i.e., the target charging power) of the electronic device to calculate the actual power adjustment amount of the electronic device, so that the target charging power may be adjusted according to the actual power adjustment amount of the electronic device and the current charging power of the electronic device.
For example, assuming that the current charging power (i.e., the target charging power) of the electronic device is Ps, the rated charging power of the electronic device is P, and the first power adjustment amount is Δ P, the actual power adjustment amount Δ P1 of the electronic device may be: Δ P1 ═ P + Δp) -Ps. If the Δ P1 is a negative value, the electronic device needs to adjust the target charging power down by Δ P1, that is, the adjusted target charging power is Ps — Δ P1; if the Δ P1 is a positive value, the electronic device needs to adjust the target charging power up to Δ P1, that is, the adjusted target charging power is Ps + Δ P1; if Δ P1 is 0, the electronic device can keep the target charging power unchanged.
In the embodiment of the invention, the electronic device can calculate the actual power adjustment amount of the electronic device according to the first power adjustment amount, the current charging power of the electronic device and the current rated charging power of the electronic device, so that the electronic device can directly adjust the target charging power according to the actual power adjustment amount without adjusting the target charging power to the current rated charging power of the electronic device first and then adjust the target charging power according to the first power adjustment amount on the basis of the rated charging power. Therefore, the speed of the electronic equipment for adjusting the target charging power according to the first power adjustment amount can be increased, and the running stability of the electronic equipment can be improved.
Optionally, in this embodiment of the present invention, in a case that the first parameter includes a heart rate of a target user operating the electronic device and an operating frequency of the target user operating the electronic device, the first target threshold may include a first threshold corresponding to the heart rate and a second threshold corresponding to the operating frequency, and the second target threshold includes a third threshold corresponding to the heart rate and a fourth threshold corresponding to the operating frequency. Then, if the heart rate of the target user is less than the first threshold or the operating frequency of the target user operating the electronic device is less than the second threshold, the electronic device may perform step 202a1 described above. If the heart rate of the target user is greater than or equal to the first threshold and less than or equal to the third threshold, and the operation frequency of the target user operating the electronic device is greater than or equal to the second threshold and less than or equal to the fourth threshold, the electronic device may perform the step 202a 2. If the heart rate of the target user is greater than the second threshold or the operating frequency of the target user operating the electronic device is greater than the fourth threshold, the electronic device may perform step 202a3 described above.
Optionally, in this embodiment of the present invention, when the first parameter includes a heart rate of a target user operating the electronic device and an operating frequency of the target user operating the electronic device, in step 202a2, the method for the electronic device to obtain the first power adjustment amount according to the first parameter may specifically include: the electronic device may obtain the first power adjustment coefficient according to the heart rate of the target user and the operating frequency of the target user for operating the electronic device, and then obtain the first power adjustment amount according to the first power adjustment coefficient and the rated charging power of the electronic device.
Optionally, in the embodiment of the present invention, the electronic device may specifically calculate the first power adjustment coefficient according to the heart rate of the target user and the operating frequency of the target user for operating the electronic device, by using a first formula; and the first power adjustment quantity can be calculated through a second formula according to the rated charging power of the terminal number equipment.
Specifically, the first formula may be R ═ [ (a-a1) × (F-F1) ]/[ k1 × (a2-a1) × k2 × (F2-F1) ].
The second formula may be: Δ P ═ R × P1.
Wherein R is a first power adjustment coefficient, R is greater than or equal to 0 and less than or equal to 1, A is the heart rate of the target user, A1 is a first threshold, F is the operating frequency of the target user for operating the electronic equipment, F1 is a second threshold, A2 is a third threshold, F2 is a fourth threshold, k1 and k2 are weight coefficients, k1 and k2 are both values which are greater than or equal to 1 and less than or equal to 2, namely k1 is greater than or equal to 1 and less than or equal to 2, and k2 is greater than or equal to 1 and less than or equal to 2; Δ P is a first power adjustment amount, and P1 is a rated charging power of the electronic device.
It should be noted that, since the weighting factor k1 may take different values within a range, and the weighting factor k2 may also take different values within a range, the first power adjustment factor calculated according to the first formula also takes a value range, and thus the first power adjustment amount also takes a value range. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Then, for example, the first power adjustment coefficient is calculated for the electronic device according to the heart rate of the target user and the operating frequency of the target user for operating the electronic device by using the first formula; a method of calculating the first power adjustment amount according to the rated charging power of the terminal number device by the second formula will be exemplarily described.
For example, assuming that the first parameters include a heart rate a of the target user and an operating frequency F of the target user operating the electronic device, a1 ≦ a2, and F1 ≦ a ≦ F2, and a rated charging power of the electronic device is P, a current charging power of the electronic device is Ps ≦ 1.2P; let it be assumed that the third threshold a2 is 1.2a1, the fourth threshold F2 is 2.3F1, and k1 is 2, and k2 is 2. If the heart rate a of the target user is a1, the power adjustment coefficient R calculated by the electronic device according to the first formula is 0, so that the first power adjustment amount calculated by the electronic device according to the second formula is 0. If the heart rate a of the target user is a2, the first power adjustment coefficient R calculated by the electronic device according to the first formula is 0.25, so that the first power adjustment amount calculated by the electronic device according to the second formula is 0.25P; furthermore, the electronic device may calculate the actual power adjustment amount Δ P1 of the electronic device as (P + Δp) -Ps as (P +0.25P) -1.2P as 0.05P > 0 based on the first power adjustment amount Δ P and the current charging power Ps of the electronic device, and then the electronic device may adjust the current charging power of the electronic device upward by 0.05P, that is, the charging power after the electronic device adjustment is 1.25P.
In the embodiment of the present invention, the electronic device may first obtain the first power adjustment coefficient according to the heart rate of the target user operating the electronic device and the operating frequency of the target user operating the electronic device, and then obtain the first power adjustment amount according to the first power adjustment coefficient. Therefore, the first power adjustment coefficient can be obtained according to the first parameter capable of reflecting the use requirement of the target user on the electronic equipment, so that the accuracy of the first power adjustment quantity obtained by the electronic equipment is high, and the accuracy of the electronic equipment for adjusting the target charging power can be improved.
Step 202b, the electronic device adjusts the working voltage of the electronic device according to the adjusted target charging power.
Optionally, in the embodiment of the present invention, the electronic device may adjust the working power of the electronic device according to the adjusted target charging power, so as to adjust the working voltage of the electronic device.
Optionally, in the embodiment of the present invention, the electronic device may linearly adjust the operating power of the electronic device at a preset ratio (for example, a fourth preset ratio) according to the adjusted target charging power, so as to adjust the operating voltage of the electronic device.
For example, the electronic device may linearly adjust the operating power of the electronic device in a ratio of 1:1 according to the adjusted target charging power; in this case, if the target charging power is increased by 40%, the operating power of the electronic device may be increased by 40%. Or the electronic device may linearly adjust the operating power of the electronic device in a ratio of 2:1 according to the adjusted target charging power; in this case, if the target charging power is increased by 40%, the operating power of the electronic device can be increased by 20%.
Optionally, in the embodiment of the present invention, the electronic device may adjust the operating voltage of the electronic device at a preset ratio (for example, a fifth preset ratio) according to the adjusted operating power, where the fifth preset ratio may be a linear ratio or a non-linear ratio. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in an embodiment of the present invention, the electronic device may adjust the operating power of the electronic device on the basis of keeping the operating current of the electronic device unchanged, so as to adjust the operating voltage of the electronic device, where a corresponding relationship between the operating voltage adjusted by the electronic device and the operating power adjusted by the electronic device is a linear relationship (P ═ U ═ I); or, the electronic device can adjust the working power of the electronic device on the basis of keeping the internal resistance of the electronic device unchanged,to adjust the operating voltage of the electronic device, in this case, the corresponding relationship between the adjusted operating voltage of the electronic device and the adjusted operating power of the electronic device is a nonlinear relationship (P ═ U-2R) is added. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
For example, assume that the operating power of the electronic device before adjustment is P2, and the operating power of the electronic device after adjustment is P3; the working voltage of the electronic equipment before adjustment is U1, and the working voltage of the electronic equipment after adjustment is U2; then, if the operating current of the electronic device is kept unchanged, P2: p3 ═ U1: u2, fifth preset scale is linear scale; if the internal resistance of the electronic device is kept unchanged, the ratio of P2: u1 ═ P32：U22I.e. the fifth predetermined proportion is a non-linear proportion.
It should be noted that, in practical implementation, when the operating power of the electronic device is increased, the temperature of the electronic device may be increased, which may result in an increase in the internal resistance of the electronic device. According to the power formula P ═ U2Assuming that the current charging power of the electronic device is P1, the current working voltage of the electronic device is U1, and the current resistance of the electronic device is R; then, if the charging power of the electronic device is increased by 3 times (i.e., increased by 4 times the original charging power), that is, P2 is 4P1, and if the resistance R is kept constant, the charging power of the electronic device is increased by 3 times, and then the operating voltage U2 of the electronic device is 2U1, that is, the operating voltage of the electronic device is increased by 1 time (i.e., increased by 2 times the original operating voltage). If the resistance R of the electronic device becomes R 'and R' is greater than R, the actual voltage U3 < U2(U2 is 2U1) of the electronic device increases by 3 times, that is, the operating voltage of the electronic device increases by a factor of less than 1 time the original operating voltage.
In the embodiment of the invention, the electronic equipment can adjust the current charging power of the electronic equipment according to the first parameter so as to adjust the working voltage of the electronic equipment, so that the defect that the electronic equipment cannot adjust the working voltage of the electronic equipment according to the first parameter due to insufficient residual electricity of a battery arranged in the electronic equipment can be avoided, and the reliability of the electronic equipment for adjusting the working voltage of the electronic equipment according to the first parameter can be improved.
Optionally, in an embodiment of the present invention, when the first parameter includes a heart rate of a target user operating the electronic device, and the heart rate of the target user is obtained by using a photoelectric measurement method, if the hand of the target user is sweaty (which may be caused by heat generation of the electronic device or by tension of the target user), the definition of an image acquired by the detector in the at least one heart rate detection module may be low (correspondingly, the blur degree of the image may be high), so that the electronic device may not obtain the heart rate of the target user from the image acquired by the detector, that is, the electronic device does not obtain the first parameter. Therefore, the electronic device may not be able to adjust the operating voltage of the electronic device according to the first parameter.
Optionally, in the embodiment of the present invention, if the electronic device does not acquire the first parameter, the electronic device may continue to acquire the second parameter, and adjust the working voltage of the electronic device according to the second parameter. The following embodiments will describe details of obtaining the second parameter, and will not be described herein.
For example, as shown in fig. 3, when the electronic device does not acquire the first parameter, the voltage control method provided in the embodiment of the present invention may further include the following steps 203 and 204.
Step 203, the electronic device acquires the second parameter when the first parameter is not acquired.
Wherein the second parameter may include at least one of: the degree of blur of the target image, the frequency of shaking of the electronic device, the temperature of the electronic device.
Optionally, in this embodiment of the present invention, the first parameter that is not acquired by the electronic device in step 203 may be a heart rate of a target user operating the electronic device, that is, the electronic device may acquire the second parameter when the electronic device does not acquire the heart rate of the target user operating the electronic device.
Optionally, in the embodiment of the present invention, the target image may be an image of a hand of a target user holding the electronic device, which is acquired by the electronic device; for example, the electronic device may acquire an image of a hand of a target user holding the electronic device through the at least one heart rate detection module. The shaking frequency of the electronic equipment can be collected through a vibration sensor in the electronic equipment, and the temperature of the electronic equipment can be collected through a temperature sensor in the electronic equipment.
Optionally, in the embodiment of the present invention, the electronic device may evaluate the blur degree of the target image through an image blur degree evaluation algorithm. The image blur degree evaluation algorithm may be: a gray variance algorithm, a gray difference absolute value sum algorithm, a gray difference square sum algorithm, or an image blur degree evaluation algorithm based on histogram concentration degree, etc. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
And step 204, the electronic equipment adjusts the working voltage of the electronic equipment according to the second parameter.
In the embodiment of the present invention, because the electronic device may increase the operating voltage of the electronic device by using the rated operating voltage of the electronic device as a reference according to the first parameter, when the electronic device cannot acquire the first parameter (i.e., the heart rate of the target user operating the electronic device), the electronic device may have a risk of having an excessively high temperature, that is, the electronic device may operate under an overload. Therefore, the electronic equipment can acquire the second parameter under the condition that the first parameter (the heart rate of a target user operating the electronic equipment) is not acquired so as to reduce the working voltage of the electronic equipment according to the second parameter; the operating voltage of the electronic equipment is reduced, so that the operating speed of the electronic equipment can be reduced, and the temperature of the electronic equipment can be reduced, and the electronic equipment can be prevented from being damaged due to overhigh temperature.
Optionally, in an embodiment of the present invention, in the possible implementation manner, the electronic device may adjust the operating voltage of the electronic device by adjusting the discharge power of a battery built in the electronic device according to the second parameter; in another possible implementation manner, the electronic device may adjust the current charging power of the electronic device according to the second parameter, and adjust the discharging power of the battery according to the adjusted charging power, so as to adjust the operating voltage of the electronic device; in yet another possible implementation manner, the electronic device may adjust the current charging power set to the electronic device according to the second parameter (in this case, the operating power of the electronic device may be a part of or all of the current charging power of the electronic device) to adjust the operating voltage of the electronic device.
For other descriptions in step 204, reference may be specifically made to the relevant description in step 202, and details are not described here.
In the embodiment of the present invention, since the second parameter related to the electronic device, such as the temperature of the electronic device, the jitter frequency of the electronic device, the temperature of the electronic device, and the like, can be used to reflect the operating state of the electronic device, the electronic device can adjust the current operating voltage of the electronic device in real time according to the parameter related to the electronic device, and can control the operating speed of the electronic device in real time, so that the operating state of the electronic device can conform to the hardware tolerance range of the electronic device. Therefore, the temperature of the electronic equipment can be effectively reduced on the basis of controlling the reliable operation of the electronic equipment, so that the operation stability and the service life of the electronic equipment can be improved.
Optionally, in the embodiment of the present invention, in the second possible implementation manner and the third possible implementation manner, the step 204 may be specifically implemented by a step 204a and a step 204b, which are described below.
And step 204a, the electronic equipment adjusts the target charging power according to the second parameter.
The target charging power may be a current charging power of the electronic device.
Optionally, in this embodiment of the present invention, the current charging power (i.e., the target charging power) of the electronic device may be greater than or equal to the rated charging power of the electronic device, and less than or equal to the maximum charging power of the electronic device.
In this embodiment of the present invention, after the electronic device adjusts the target charging power according to the second parameter, the adjusted target charging power may be smaller than or equal to a rated charging power of the electronic device.
Optionally, in the embodiment of the present invention, after the electronic device obtains the second parameter, it is first determined whether the second parameter meets a preset condition, and the electronic device may adjust the target charging power according to the second parameter when the second parameter meets the preset condition (that is, the second parameter is the same as the second parameter, or the matching degree of the second parameter is greater than the first preset threshold).
Specifically, if the second parameter includes the blur degree of the target image, the preset condition may include that the blur degree of the image is within a preset blur degree range. Wherein, presetting the ambiguity range comprises: the first preset ambiguity range, the second ambiguity preset range and the third preset ambiguity range. That is, the electronic device may adjust the target charging power according to the blur degree of the target image when the blur degree of the target image is within the first preset blur degree range, the second preset blur degree range, or the third preset blur degree range.
If the second parameter includes a jitter frequency of the electronic device, the preset condition may include that the jitter frequency of the electronic device is within a preset frequency range. That is, in the case that the dithering frequency of the electronic device is within the preset frequency range, the electronic device may adjust the target charging power according to the dithering frequency of the electronic device.
If the second parameter is the temperature of the electronic device, the preset condition may include that the temperature of the electronic device is greater than a preset temperature threshold. That is, in the case where the temperature of the electronic device is greater than the temperature threshold, the electronic device may adjust the target charging power according to the temperature of the electronic device.
When the second parameter includes at least two parameters of the blur degree of the target image, the jitter frequency of the electronic device, and the temperature of the electronic device, the electronic device may adjust the target charging power according to the second parameter, which may be combined with a method for adjusting the target charging power according to the blur degree of the target image, the jitter frequency of the electronic device, or the temperature of the electronic device, and therefore, details are not repeated here to avoid repetition.
Optionally, in the embodiment of the present invention, in the case that the second parameter includes a degree of blur of the target image, a shaking frequency of the electronic device, and a temperature of the electronic device, the step 204a may be specifically implemented by the following step 204a1, step 204a2, or step 204a 3.
Step 204a1, when the ambiguity of the target image is within a first preset ambiguity range, the dithering frequency of the electronic device is within a preset frequency range, and the temperature of the electronic device is greater than a temperature threshold, the electronic device linearly reduces the target charging power according to a first preset proportion.
Step 204a2, when the ambiguity of the target image is within a second preset ambiguity range, the dithering frequency of the electronic device is within a preset frequency range, and the temperature is greater than the temperature threshold, the electronic device linearly reduces the target charging power according to a second preset proportion.
Step 204a3, when the ambiguity of the target image is within a third preset ambiguity range, the dithering frequency of the electronic device is within a preset frequency range, and the temperature of the electronic device is greater than the temperature threshold, the electronic device linearly reduces the target charging power according to a third preset proportion.
The upper limit value of the first preset ambiguity range is smaller than the lower limit value of a second preset ambiguity range, and the upper limit value of the second preset ambiguity range is smaller than the lower limit value of a third preset ambiguity range; the first preset proportion is smaller than the second preset proportion, and the second preset proportion is smaller than the third preset proportion.
Optionally, in the embodiment of the present invention, the ambiguity of the image may be represented by a probability α that each gray value in the gray histogram corresponding to the image appears near a gray mean of the gray histogram, where the larger α is, the higher the ambiguity of the image is, and α is greater than or equal to 0 and less than or equal to 1.
Optionally, in this embodiment of the present invention, the first preset ambiguity range may be an ambiguity range corresponding to an image (which may be multiple images) capable of recognizing a blood flow change of a capillary vessel in a fuzzy manner, for example, a value range of α may be 0 ≦ α ≦ 0.3. The second preset ambiguity range may be an ambiguity range corresponding to an image (which may be a plurality of images) in which blood flow changes of capillaries are hardly recognized, for example, the value range of α may be 0.3 < α ≦ 0.6. The third preset ambiguity range may be an ambiguity range corresponding to an image (which may be multiple images) in which blood flow changes of capillaries cannot be completely identified, for example, the value range of α may be 0.6 < α ≦ 1. The specific value ranges of the first preset ambiguity range, the second preset ambiguity range and the third preset ambiguity range can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in this embodiment of the present invention, the temperature threshold may be a temperature value smaller than an upper temperature limit that can be borne by the electronic device. For example, if the upper temperature limit of the temperature protection system of the electronic device is 50 °, the temperature threshold may be any temperature value smaller than 50 °, such as 35 °, 40 °, or 45 °.
Optionally, in an embodiment of the present invention, the first predetermined ambiguity range may correspond to a first predetermined ratio range, the second predetermined ambiguity range may correspond to a second predetermined ratio range, and the third predetermined ambiguity range may correspond to a third predetermined ratio range. The first preset proportion may be a numerical value in a first preset proportion range, the second preset proportion may be a numerical value in a second preset proportion range, and the third preset proportion may be a numerical value in a third preset proportion range.
Specifically, in the embodiment of the present invention, the electronic device may determine each preset ratio according to each preset ratio range and a jitter frequency of the electronic device.
For example, the electronic device may determine the first preset proportion according to a first preset proportion range and a jitter frequency of the electronic device. The electronic device may determine the second preset proportion according to the second preset proportion range and a jitter frequency of the electronic device. The electronic device may determine the third preset proportion according to the third preset proportion range and a jitter frequency of the electronic device.
Optionally, in the embodiment of the present invention, each of the preset ratio ranges corresponds to a preset jitter frequency range.
For example, the first preset ratio range is [ 0%, 40% ], and the preset jitter frequency range is [4, 8] times/second, i.e., [ 0%, 40% ] corresponds to [4, 8 ]. Specifically, 0% corresponds to 4, 10% corresponds to 5, 20% corresponds to 6, 30% corresponds to 7, and 40% corresponds to 8. For another example, the second predetermined ratio range is [ 20%, 60% ], and the predetermined dithering frequency range is [4, 8] times/second, i.e., [ 20%, 60% ] corresponds to [4, 8 ]. Specifically, 20% corresponds to 4, 30% corresponds to 5, 40% corresponds to 6, 50% corresponds to 7, and 60% corresponds to 8. For another example, the third predetermined ratio range is [ 40%, 80% ], the predetermined dithering frequency range is [4, 8] times/second, [ 40%, 80% ] corresponds to [4, 8 ]. Specifically, 40% corresponds to 4, 50% corresponds to 5, 60% corresponds to 6, 70% corresponds to 7, and 80% corresponds to 8. In an embodiment of the present invention, each of the preset ratios may be a multiple of 10.
It can be understood that, according to each preset proportion range and the jitter frequency of the electronic device, the method for determining each preset proportion by the electronic device may specifically be: the electronic equipment determines the position of the dithering frequency within a preset dithering frequency range according to the dithering frequency of the electronic equipment, and then determines the numerical value at the position in each preset proportion range as each preset proportion according to the position.
Optionally, in the embodiment of the present invention, the method for determining, by the electronic device, the first preset ratio according to the first preset ratio range and the jitter frequency of the electronic device may specifically be: the electronic equipment determines the position of the dithering frequency within a preset dithering frequency range according to the dithering frequency of the electronic equipment, and then determines the value at the position in a first preset proportion range as a first preset proportion according to the position. For example, assuming that the preset dithering frequency range is [4, 8] times/second and the dithering frequency of the electronic device is 5 times/second, the electronic device may determine the 2 nd position of the dithering frequency of the electronic device from small to large in the preset dithering frequency [4, 8] times/second. Thus, the electronic device may determine that the value of the 2 nd position from small to large in the first preset proportion range [ 0%, 40% ], i.e., 10%, is 10% according to the 2 nd position, and the first preset proportion is 10%. That is, the electronic device may lower the target charging power (i.e., the current charging power of the electronic device) by 10%.
Optionally, in the embodiment of the present invention, the method for determining, by the electronic device, the second preset ratio according to the second preset ratio range and the jitter frequency of the electronic device may specifically be: the electronic equipment determines the position of the dithering frequency within the preset dithering frequency range according to the dithering frequency of the electronic equipment, and then determines the value at the position in the second preset proportion range as a second preset proportion according to the position. For example, assuming that the preset dithering frequency range is [4, 8] times/second and the dithering frequency of the electronic device is 6 times/second, the electronic device may determine the 3 rd position of the dithering frequency of the electronic device from small to large in the preset dithering frequency [4, 8] times/second. Thus, the electronic device may determine, according to the 3 rd position, that is, 40% which is a numerical value of the 3 rd position from small to large in the second preset proportion range [ 20%, 60% ] as that the second preset proportion is 40%.
