The drawings illustrate preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As described in the background art, with the wide application 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, the existing strategies mainly comprise clock gating, power gating, multi-voltage domain power supply and the like, but the low-power-consumption control methods cannot control power consumption by combining specific application scenes and application requirements, so that the power consumption control effect is poor.
Based on this, the embodiment of the application provides a power consumption control device, a power consumption control method, an electronic device and a computer readable storage medium.
In some embodiments, a power consumption control device is provided and applied to an electronic device, where the electronic device includes a sensor and a scanning module connected with 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 the impedance of a human body, a photoelectric sensor, or the like. The pressure sensor is described herein as an example only.
Specifically, the pressure sensor converts pressure into a voltage signal, and the scanning module collects and converts the voltage signal so that the processor can perform operation processing.
As shown in fig. 1, the power consumption control apparatus 100 provided in this embodiment includes a configuration module 10, a first control module 20, a processing module 30, and a second control module 40.
Wherein the configuration module 10 is used for configuring the timing parameter of the current period and the scanning parameter of the scanning module.
Specifically, the whole process includes a plurality of scanning periods, and before the scanning module is controlled to collect data, the configuration module 10 may configure timing parameters of the period where the current period is located and scanning parameters of the scanning module. In some embodiments, the scan parameters may include parameters of scan mode, scan channel number, scan period, voltage gain amplification, etc., and the timing parameters may include parameters related to a timer.
It should be noted that, the step of configuring the timing parameters and the scanning parameters by the configuration module 10 may be performed at the initial stage of the current period, or may be performed at other time stages of the current period, which only needs to ensure that the configuration is completed before the scanning module performs scanning.
The first control module 20 is configured to control the electronic device to enter a first sleep mode and control the scanning module to collect sensing data of the sensor in a first preset time period of the current period according to the scanning parameter and the timing parameter.
Specifically, when the configuration module 10 configures the scan parameters and the timing parameters, the first control module 20 may control the electronic device to enter the first sleep mode and control the scan module to collect sensing data of the sensor in a first preset period of the current period. The first preset time period in the current period 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 is not limited herein.
It should be noted that other power consumption modules may also be included in the electronic device. The first sleep mode may refer to the electronic device only turning on the modules related to the timing function and the scanning function, and turning off the other modules, so that the electronic device operates in a lower power consumption operation mode. In this embodiment, the first control module 20 may control the electronic device to enter the first sleep mode in the process of controlling the scanning module to collect the sensing data of the sensor, which is beneficial to reducing power consumption.
The processing module 30 is configured to process, in a normal operation mode, the sensing data collected by the scanning module in a first preset period of a current cycle or a previous cycle.
Specifically, the normal operation mode may refer to a state opposite to the sleep mode, and refers to a state in which the electronic device is operating normally without entering the sleep mode. The processing module 30 may process the sensing data collected by the scanning module in the current period or the first preset period of the previous period in the normal working mode, and the processing procedure may include amplifying the collected analog signal and converting the amplified analog signal into a digital signal.
The second control module 40 is configured to control the electronic device to enter a second sleep mode and control the scanning module to stop collecting the sensing data in a second preset time period of the current period according to the timing parameter.
Specifically, the second control module 40 may control the electronic device to enter the second sleep mode and control the scanning module to stop collecting the sensing data during the second preset period of the current period. The second preset time period of the current period 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 is not limited herein. The second sleep mode may refer to the electronic device only turning on the module (e.g., timer) associated with the timing function and turning off the other modules so that the electronic device operates in a lower power consumption mode of operation. In this embodiment, the second control module 40 may control the electronic device to enter the second sleep mode in the process of controlling the scanning module to stop collecting the sensing data of the sensor, which is beneficial to reducing power consumption. It is to be understood that the power consumption in the second sleep mode is smaller than the power consumption in the first sleep mode.
According to the power consumption control device, the first control module controls the electronic equipment to enter the first sleep mode and controls the scanning module to collect sensing data of the sensor in a first preset time period of the current period according to the scanning parameters and the timing parameters, and the second control module controls the electronic equipment to enter the second sleep mode and controls the scanning module to stop collecting the sensing data in a second preset time period of the current period according to the timing parameters. Therefore, the power consumption can be reasonably controlled according to specific application scenes and application requirements, and the overall power consumption is further reduced.
In some of these embodiments, the power consumption control apparatus sequentially operates the processing module 30, the configuration module 10, the first control module 20, and the second control module 40 after the electronic device enters the current cycle. The processing module 30 may process the sensing data collected by the scanning module during the first preset period of the previous cycle in the normal operation mode.
Specifically, during the current period, the processing module 30 first processes the sensing data collected by the scanning module during the first preset period of the previous period in the normal operation mode. After the processing module 30 has completed its work, the configuration module 10 may configure the timing parameters of the current cycle and the scanning parameters of the scanning module. After the configuration module 10 completes the configuration, the first control module 20 may control the electronic device to enter the first sleep mode and control the scanning module to collect sensing data of the sensor in a first preset period of the current period according to the scanning parameter and the timing parameter. After the first control module 20 completes the work, the second control module 40 may control the electronic device to enter the second sleep mode and control the scanning module to stop collecting the sensing data in a second preset time period of the current period according to the timing parameter.
That is, in the previous period, after the configuration module 10 configures the scan parameters and the timing parameters, the first control module 20 controls the scan module to complete the data acquisition in the first preset period, the processing module 30 does not process the data acquired by the scan module, and the second control module 40 directly controls the scan module to enter the second sleep mode. After entering the current period, the processing module 30 processes the sensing data collected in the first preset time period of the previous period, and then the configuration module 10 reconfigures the timing parameter of the current period and the scanning parameter of the scanning module. The time that the electronic device is in the second sleep mode can be increased, and the power consumption in each period can be further reduced.
In some of these embodiments, the power consumption control apparatus sequentially operates the configuration module 10, the first control module 20, the processing module 30, and the second control module 40 after the electronic device enters the current cycle. The processing module 30 may process the sensing data collected by the scanning module during the first preset time period of the current period in the normal operation mode.
Specifically, during the current period, the configuration module 10 first configures the timing parameters of the current period and the scan parameters of the scan module. After the configuration module 10 completes the configuration, the first control module 20 may control the electronic device to enter the first sleep mode and control the scanning module to collect sensing data of the sensor in a first preset period of the current period according to the scanning parameter and the timing parameter. After the first control module 20 completes the work, the processing module 30 processes the sensing data collected by the scanning module in the first preset time period of the current period in the normal working mode. After the processing module 30 completes the work, the second control module 40 may control the electronic device to enter the second sleep mode and control the scanning module to stop collecting the sensing data in a second preset period of the current period according to the timing parameter.
That is, in the current period, after the scan module is controlled to complete data acquisition and before the scan module is controlled to stop data acquisition, the processing module 30 processes the sensing data acquired by the scan module in the first preset period. After the processing module 30 processes the data, the second control module 40 may enter a second preset period of the current period, i.e. only start the module related to the timing function, such as a timer, close the other modules, and control the electronic device to operate in the second sleep mode, so as to reduce the power consumption of the electronic device to the greatest extent. In addition, the collected data is processed in time after the data collection is completed, so that the response speed is improved, and meanwhile, the phenomenon that the data is lost or other abnormal conditions are caused by the fact that the collected data is not processed in time is avoided, and the data processing is further affected.
In some embodiments, the electronic device further includes a power management module, as shown in fig. 2, the apparatus 100 further includes:
and a third control module 50, configured to control the power management module to enter a low power consumption mode during a second preset period of the current period.
In particular, the power management module is used to power other modules in the electronic device. The third control module 50 may control the power management module to enter a low power mode according to timing parameters. In a second preset time period of the current period, the scanning module stops collecting the sensing data, and at the moment, the power management module in the electronic equipment becomes a main power consumption source, and the condition of switching the power management module from a normal working mode to a low power consumption mode is provided because the load in the electronic equipment is very low at the moment. 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 some of these embodiments, the power management module is a low dropout linear regulator (Low Dropout regulator, LDO). A low dropout linear regulator is a voltage converter for subtracting an excess voltage from an input voltage, and outputting a voltage value required for a load, for example, from 5V to 3.3V.
Specifically, the third control module 50 may reduce the load carrying capability of the low dropout linear regulator to a preset value during the second preset time period of the current period. When the low dropout linear regulator is in the normal operation mode, the load in the electronic device is high, so that the load carrying capacity of the low dropout linear regulator needs to be kept high, and further the power consumption is high. When the scanning module stops collecting data in the second preset time period of the current period, the modules which need to keep working normally are fewer, so that the load in the whole electronic equipment is lower, the low-dropout linear voltage regulator does not need to keep strong carrying capacity, namely, the carrying capacity of the low-dropout linear voltage regulator can be reduced to a preset value, and the electricity consumption requirement of the modules which work normally in the second preset time period is met. Regarding the preset value, it may be set according to the power demand of the module that normally operates in the second preset period of time, and is not particularly limited herein.
In some of these embodiments, the electronic device further comprises a timer. The timer, as a module of the electronic device associated with the timing function, may be started during a second preset time period of the current cycle. That is, the second control module 40 may control the electronic device to start only the timer for a second preset period of the current period.
In some embodiments, as shown in fig. 3, the power consumption control apparatus 100 further includes a wake-up module 60, where the wake-up module 60 is configured to generate an interrupt wake-up signal after the second control module 40 controls the scan module to stop collecting the sensing data, and the interrupt wake-up signal is configured to wake up the electronic device to enter the power consumption control flow of the next cycle after the second preset period of the current cycle is completed.
Specifically, after the second control module 40 controls the scanning module to stop collecting the sensing data, the wake-up module 60 may generate an interrupt wake-up signal to wake-up the electronic device to enter the power consumption control flow of the next cycle. The interrupt wake-up signal may be preset when the configuration module 10 configures the timing parameter of the current period, and may generally be a timer, so that the timer may wake-up the interrupt system at the end of the second preset period of the current period. The electronic equipment automatically enters the power consumption control flow of the next period through the interrupt awakening of the awakening module 60, so that the continuous operation of the electronic equipment is facilitated.
The power consumption control flow entering the next cycle is that when the next cycle starts, the processing module 30, the configuration module 10, the first control module 20, and the second control module 40 work sequentially, or the configuration module 10, the first control module 20, the processing module 30, and the second control module 40 work sequentially.
The respective modules in the above-described power consumption control apparatus may be implemented in whole or in part by software, hardware, and combinations thereof. The above modules may be embedded in hardware or may be independent of a processor in the computer device, or may be stored in software in a memory in the computer device, so that the processor may call and execute operations corresponding to the above modules. It should be noted that, in the embodiment of the present disclosure, the division of the modules is merely a logic function division, and other division manners may be implemented in actual practice.

The implementation of the solution to the problem provided by the method is similar to that described in the above-mentioned device, so the specific limitation in the method embodiments of the power consumption control device or devices provided below may be referred to the limitation of the power consumption control device hereinabove, and will not be repeated here.

T1: the electronic equipment is in a normal working mode, the configuration module 10 works, the electronic equipment executes the step A10, namely, the scanning mode, the scanning channel number, the voltage gain amplification factor and the scanning finishing wake-up enabling of the analog front end are configured through the microcontroller core through a bus, and meanwhile, the counting period of the timer is configured. When the configuration module 10 completes the above configuration, the first control module 20 controls the electronic device to enter the first sleep mode.
T2: the electronic device is in a first sleep mode. In this mode, the first control module 20 works, and the electronic device specifically executes step a20, and at this time, may turn off the clock except the pressure-sensitive peripheral device and the timer, and control the pressure-sensitive peripheral device to scan. In the first sleep mode, the clock except the pressure sensing peripheral and the timer is turned off, 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 completing data acquisition in the first preset time period, the interrupt wakeup system may be triggered to enter T3.
T3: the electronic device is in a normal working mode, the processing module 30 works, and the electronic device executes the step A30, namely, the processing of the sensing data acquired by the sensing peripherals in the first preset time period. After the data processing is completed, the second control module 40 controls the electronic device to enter the second sleep mode.
T4: the electronic device is in a second sleep mode. In this mode, the second control module 40 works, and the electronic device specifically executes step a40, i.e. controls the scanning module to stop data acquisition. At this time, all clocks except the timer may be turned off, and step a42 is performed, i.e., the load capacity of the low dropout linear regulator is reduced to a preset value, so that it operates in the low power consumption mode. In the second sleep mode, since all clocks except the timer are turned off and the load carrying capability of the low dropout linear regulator is reduced to a preset value, power consumption in the second sleep mode is further reduced compared to the first sleep mode. In this embodiment, T4 is the aforementioned second preset period, in which the electronic device waits for the timer to wake up overtime, and when the timer generates the interrupt wake-up signal overtime, the electronic device enters the T1 phase of the next cycle.
In the specific example, after the data is collected, the collected data is processed in time, so that the response speed is improved, and meanwhile, the phenomenon that the data is lost or other abnormal conditions are caused by not processing the collected data in time is avoided, and further the data processing is affected.
The following is another specific example of the power consumption control method applied to the above-described electronic device (see fig. 10):
t1: the electronic device is in the normal working mode, the processing module 30 works, and the electronic device executes step B10, namely, processes the data acquired by the peripheral device with the internal pressure sense in the previous period. After the data processing is finished, the configuration module 10 works, and the electronic device executes step B20, namely, configures the scan mode, the scan channel number, the voltage gain amplification factor and the scan completion wakeup enable of the analog front end through the microcontroller core via the bus, and configures the counting period of the timer. When the configuration module 10 completes the above configuration, the first control module 20 controls the electronic device to enter the first sleep mode.
T2: the electronic device is in a first sleep mode. In this mode, the first control module 20 operates, and the electronic device specifically executes step B30, where the clocks other than the clock and the timer of the pressure-sensitive peripheral device may be turned off, so as to control the pressure-sensitive peripheral device to scan. In the first sleep mode, since all clocks except the pressure-sensitive peripheral clock and the timer are turned off, power consumption of the electronic device is reduced to some extent while the data acquisition function is ensured. In this embodiment, T2 is the aforementioned first preset time period, and after completing data acquisition in the first preset time period, the interrupt wakeup system may be triggered to enter T3.
T3: the electronic device is in a second sleep mode. In this mode, the second control module 40 works, and the electronic device specifically executes step B40, i.e. controls the scanning module to stop data acquisition. At this time, all clocks except the timer may be turned off, and step B42 of reducing the load capacity of the low dropout linear regulator to a preset value is performed to operate in the low power consumption mode. In the second sleep mode, since all clocks except the timer are turned off and the load carrying capability of the low dropout linear regulator is reduced to a preset value, power consumption in the second sleep mode is further reduced compared to the first sleep mode. In this embodiment, T3 is the aforementioned second preset period, in which the electronic device waits for the timer to wake up overtime, and when the timer generates the interrupt wake-up signal overtime, the electronic device enters the T1 phase of the next cycle.
Compared with the first specific example, the second specific example combines the configuration of the pressure sensing peripheral and the data processing stage, reduces the process of waking the electronic device from the first sleep mode once, increases the time of the system in the second sleep mode, and further reduces the power consumption of the whole period.
