The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As described in the background art, with the widespread use of mobile terminal chip products and the bottleneck of battery technology, low power consumption has become one of the current core indexes. In order to realize low-power-consumption operation, currently, clock gating, power gating, multi-voltage-domain power supply and the like are mainly used in the existing strategies, but the low-power-consumption control methods cannot be combined with specific application scenes and application requirements to control power consumption, so that the power consumption control effect is poor.
Based on this, embodiments of the present application provide a power consumption control method, a power consumption control apparatus, an electronic device, and a computer-readable storage medium.
In some embodiments, the present application provides a power consumption control method, which is applied to an electronic device including a sensor and a scanning module connected to the sensor. The sensor may be a pressure sensor, a capacitive touch sensor for a touch screen or a touch key, an impedance detection sensor for monitoring human body impedance, a photoelectric sensor, or the like. The pressure sensor is only used as an example for explanation.
Specifically, the pressure sensor converts the pressure into a voltage signal, and the scanning module collects and converts the voltage signal so as to facilitate the processor to perform operation processing.
As shown in fig. 1, the power consumption control method provided in this embodiment includes the following steps:
step S20: and configuring the timing parameters of the current period and the scanning parameters of the scanning module.
Specifically, the whole process includes a plurality of scanning cycles, and before controlling the scanning module to collect data, the timing parameters of the current cycle and the scanning parameters of the scanning module need to be configured, where the scanning parameters may include parameters such as a scanning mode, a scanning channel number, a scanning cycle, and a voltage gain amplification factor, and the timing parameters include related parameters of a timer.
It should be noted that the step of configuring the timing parameter and the scanning parameter may be performed at an initial stage of the current period, or may be performed at other time stages of the current period, and it is only required to ensure that the configuration is completed before the scanning module performs the scanning.
Step S40: and controlling the scanning module to acquire the sensing data of the sensor in a first preset time period of the current period according to the scanning parameters and the timing parameters.
When the scanning parameters and the timing parameters are configured, the scanning module can be controlled to acquire the sensing data of the sensor within a first preset time period of the current period. The first preset time period in the current cycle may be set when the timing parameter is configured, and the specific duration and the starting time of the first preset time period may be set according to the actual application scenario and the application requirement, which are not limited herein.
It should be noted that the electronic device may further include other power consuming modules. As a preferred embodiment, in the process of controlling the scanning module to collect the sensing data of the sensor, only the modules related to the timing function and the scanning function may be turned on, and the other modules may be turned off, so that the electronic device may operate in a lower power consumption operating mode (hereinafter, referred to as a first sleep mode), which is beneficial to reduce power consumption.
Step S60: and controlling the scanning module to stop acquiring the induction data within a second preset time period of the current period according to the timing parameters.
When the scanning module finishes the data acquisition step in the first preset time period, the scanning module can be controlled to stop acquiring the induction data in the second preset time period of the current period. The second preset time period of the current cycle may be set when the timing parameter is configured, and the specific duration and the starting time of the second preset time period may be set according to the actual application scenario and the application requirement, which are not limited herein.
As a preferred embodiment, during the second preset time period, only the module related to the timing function, such as the timer, may be turned on, and other modules may be turned off, so that the electronic device may operate in an operating mode with lower power consumption (hereinafter, referred to as the second sleep mode), thereby further reducing power consumption. Wherein the power consumption in the second sleep mode is less than the power consumption in the first sleep mode.
According to the power consumption control method, a first preset time period and a second preset time period are set in one period, the scanning module is controlled to collect the sensing data of the sensor in the first preset time period according to the preset timing parameters and the scanning parameters of the scanning module, the scanning module is controlled to stop collecting the sensing data in the second preset time period according to the timing parameters, therefore, in the same period, the time for the scanning module to collect the data and the time for the scanning module to stop collecting the data can be reasonably controlled according to specific application scenes and application requirements, the power consumption is further reasonably controlled, and the overall power consumption of the electronic equipment is controlled in a lower range.
In some embodiments, as shown in fig. 2, before step S60, that is, before the step of controlling the scan module to stop acquiring the sensing data within the second preset time period of the current cycle according to the timing parameter, the power consumption control method provided in this embodiment further includes the following steps:
step S50: and processing the induction data acquired by the scanning module in a first preset time period of the current cycle.
After controlling the scanning module to complete data acquisition and before controlling the scanning module to stop data acquisition, the sensing data acquired by the scanning module in a first preset time period is processed, and the processing flow may include amplifying the acquired analog signal and converting the analog signal into a digital signal, and the like. In this step, the electronic device is in a normal operating mode. The normal operating mode is opposite to the sleep mode, and refers to a state in which the electronic device normally operates and does not enter the first sleep mode or the second sleep mode.
After the data is processed, a second preset time period of the current cycle can be entered, that is, only the module related to the timing function, such as the timer, is started, other modules are closed, the electronic device is controlled to operate in the second sleep mode, and the power consumption of the electronic device is reduced to the maximum extent. In addition, the acquired data are processed in time after the data acquisition is finished, so that the response speed is improved, and meanwhile, the data loss or other abnormal conditions caused by the fact that the acquired data are not processed in time are avoided, and further the data processing is influenced.
In some embodiments, as shown in fig. 3, before step S20, that is, the step of configuring the timing parameter of the current cycle and the scanning parameter of the scanning module, the power consumption control method provided by this embodiment further includes the following steps:
step S10: and processing the induction data acquired by the scanning module in a first preset time period of the last period.
That is, in the previous cycle, after the scanning parameters and the timing parameters are configured, the scanning module is controlled to complete data acquisition in the first preset time period, and the data acquired by the scanning module is not processed, but directly enters the second sleep mode. After entering the current period, firstly processing the induction data collected in the first preset time period of the previous period, and then configuring the timing parameters of the current period and the scanning parameters of the scanning module. The time that the electronic device is in the second sleep mode can thereby be increased, further reducing power consumption per cycle.
In some embodiments, the electronic device further includes a power management module, and the power management module is configured to supply power to other modules in the electronic device. As shown in fig. 4a and 4b, in step S60, that is, while controlling the scan module to stop collecting the sensing data in the second preset time period of the current cycle according to the timing parameter, the power consumption control method provided in this embodiment further includes the following steps:
step S61: and controlling the power management module to enter a low power consumption mode within a second preset time period of the current cycle.
When the scanning module is controlled to stop collecting the induction data, the power management module in the electronic device becomes a main power consumption source, and the load in the electronic device is very low, so that the condition that the power management module is switched from the normal working mode to the low power consumption mode is provided. And controlling the power management module to enter a low power consumption mode in a second preset time period of the current period, so that the power consumption of the current stage can be further reduced.
In one embodiment, the power management module is a Low dropout linear regulator (LDO). A low dropout linear regulator is a voltage converter for subtracting an excess voltage from an input voltage to output a voltage value required by a load, for example, from 5V to 3.3V.
Specifically, in step S61, the step of controlling the power management module to enter the low power consumption mode in the second preset time period of the current cycle includes: and reducing the loading capacity of the low dropout linear regulator to a preset value in a second preset time period of the current cycle.
When the low dropout regulator is in a normal operating mode, the load in the electronic device is high, so that the load capacity of the low dropout regulator needs to be kept high, and the power consumption is high. And when being in the second preset time quantum of current cycle, because the scanning module has stopped to gather data, need to keep the module of normal work less, consequently the load in whole electronic equipment is lower, and low dropout linear regulator then need not to keep stronger on-load ability, namely, can reduce the on-load ability of low dropout linear regulator to the default to guarantee in the second preset time quantum normally the module of working the power consumption demand can. The preset value may be set according to the power demand of the module that normally operates in the second preset time period, and is not particularly limited herein.
In one embodiment, as shown in fig. 5, after step S60, that is, after the step of controlling the scan module to stop acquiring the sensing data within the second preset time period of the current cycle according to the timing parameter, the power consumption control method provided in this embodiment further includes the following steps:
step S70: and generating an interrupt awakening signal, wherein the interrupt awakening signal is used for awakening the electronic equipment to enter a power consumption control flow of the next period after the second preset time period of the current period is finished.
After the second preset time period of the current cycle is finished, an interrupt awakening signal can be generated to awaken the electronic equipment to enter a power consumption control flow of the next cycle. The interrupt wake-up signal may be preset when the timing parameter of the current cycle is configured in step S20, and may be generally set by setting a timer, so that the timer can wake up the interrupt system at the end of the second preset time period of the current cycle. The electronic equipment automatically enters the power consumption control flow of the next period in an interrupt awakening mode, and the continuous operation of the electronic equipment is facilitated.
The power consumption control flow of the next cycle, i.e. the series of steps described above are re-executed at the beginning of the next cycle, may be executed first in step S20, or may be executed first in step S10.
The hardware structure of the electronic device has various embodiments, and in order to describe the technical solution of the present application more clearly, the following describes the above power consumption control method with reference to one specific example of the electronic device:
in one specific example, as shown in fig. 6, the electronic device includes a microcontroller core (core), a Bus (Bus), a Memory (Memory), a Power management Unit (Power management Unit, abbreviated PMU), a clock reset Controller (RestClock Controller, abbreviated RCC), a Low Dropout Regulator (LDO), a clock Oscillator (Oscillator, abbreviated OSC), an analog Front end (analog Front-end, abbreviated AFE), a Sensor (Sensor), and a Timer (Timer), wherein the AFE typically includes an analog-to-digital converter (ADC), a Programmable Gain Amplifier (Programmable Gain Amplifier, abbreviated PGA), and a channel multiplexer (IO MUX). Specifically, the memory, the analog front end, the power consumption management unit, the clock reset controller and the timer are all connected with the microcontroller core through a bus. The analog front end is connected with the sensor to form a pressure sensing peripheral. The power consumption management unit is respectively connected with the analog front end, the low dropout linear regulator, the clock reset controller and the timer, and the clock reset controller is also respectively connected with the timer and the clock oscillator.
The following is a specific example of a power consumption control method applied to the above electronic device:
as shown in FIG. 7, TcycleT1-T4 represent 4 periods in a scan cycle.
T1: the electronic device is in a normal operating mode, and step S20 is executed, that is, the scan mode, the scan channel number, the voltage gain amplification factor, and the scan completion wake-up enable of the analog front end are configured through the microcontroller core via the bus, and the counting period of the timer is configured at the same time. And entering a first sleep mode after the configuration is completed.
T2: the electronic device is in a first sleep mode. In this mode, the electronic device executes step S40, and at this time, the clock except for the pressure-sensitive peripheral and the timer is turned off to control the pressure-sensitive peripheral to perform scanning. When in the first sleep mode, the clock except the pressure-sensitive peripheral and the timer is closed, so that the power consumption of the electronic equipment is reduced to a certain extent while the data acquisition function is ensured. In this embodiment, T2 is the aforementioned first preset time period, and after the data acquisition in the first preset time period is completed, the interrupt wake-up system may be triggered to enter T3.
T3: the electronic device is in a normal operating mode, and step S50 is executed, that is, the sensing data collected by the pressure sensing peripheral device within the first preset time period is processed. And after the data processing is finished, entering a second sleep mode.
T4: the electronic device is in a second sleep mode. In this mode, the electronic device specifically executes step S60, that is, controls the scanning module to stop data acquisition. At this time, all clocks except the timer may be turned off, and step S61 is executed to reduce the load capacity of the low dropout regulator to a preset value, so as to operate in the low power consumption mode. When in the second sleep mode, because all clocks except the timer are turned off and the loading capacity of the low dropout linear regulator is reduced to a preset value, the power consumption in the second sleep mode is further reduced compared with the first sleep mode. In this embodiment, T4 is the aforementioned second preset time period, and in the second preset time period, the electronic device waits for the timer to wake up when the timer times out, and when the timer times out and generates the interrupt wake-up signal, the electronic device enters the T1 phase of the next cycle.
In the above specific example, after the data is collected, the collected data is processed in time, which is helpful for improving the response speed, and meanwhile, the data loss or other abnormal conditions caused by the fact that the collected data is not processed in time are avoided, and further the data processing is influenced.
The following is another specific example of the power consumption control method applied to the above-described electronic device (see fig. 8):
t1: the electronic device is in a normal operation mode, and step S10 is executed to process the data collected by the pressure sensing peripheral device in the previous cycle. After the data processing is finished, step S20 is executed, that is, the scan mode, the scan channel number, the voltage gain amplification factor and the scan completion wake-up enable of the analog front end are configured through the microcontroller core via the bus, and the counting period of the timer is configured at the same time. And entering a first sleep mode after the configuration is completed.
T2: the electronic device is in a first sleep mode. In this mode, the electronic device executes step S40, and at this time, the clock other than the pressure-sensitive peripheral clock and the timer is turned off to control the pressure-sensitive peripheral to perform scanning. In the first sleep mode, all clocks except the pressure-sensitive peripheral clock and the timer are closed, so that the power consumption of the electronic equipment is reduced to a certain extent while the data acquisition function is ensured. In this embodiment, T2 is the aforementioned first preset time period, and after the data acquisition in the first preset time period is completed, the interrupt wake-up system may be triggered to enter T3.
T3: the electronic device is in a second sleep mode. In this mode, the electronic device specifically executes step S60, that is, controls the scanning module to stop data acquisition. At this time, all clocks except the timer may be turned off, and step S61 is executed to reduce the load capacity of the low dropout regulator to a preset value, so as to operate in the low power consumption mode. When in the second sleep mode, because all clocks except the timer are turned off and the loading capacity of the low dropout linear regulator is reduced to a preset value, the power consumption in the second sleep mode is further reduced compared with the first sleep mode. In this embodiment, T3 is the aforementioned second preset time period, and in the second preset time period, the electronic device waits for the timer to wake up when the timer times out, and when the timer times out and generates the interrupt wake-up signal, the electronic device enters the T1 phase of the next cycle.
Compared with the first specific example, the second specific example combines the pressure-sensitive peripheral configuration and the data processing stage, reduces the process of waking up the electronic device from the first sleep mode at a time, increases the time of the system in the second sleep mode, and further reduces the power consumption of the whole cycle.
