[0022] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0023] First, some nouns involved in this application are analyzed: Embedded low power management: is a method to optimize the energy consumption of embedded systems, mainly used for battery-powered devices or devices that need to run for a long time. Its core goal is to extend the battery life of the device or reduce the power consumption of the device through effective power management and energy-saving technology. It is mainly used to dynamically manage various peripherals of microcontroller units or electronic pen devices.

[0024] The following will be combined Figures 1 to 5 The power consumption management method of the embodiment of the present invention is described clearly and completely. Obviously, the embodiment described below is only a part of the embodiments of the present invention, not all the embodiments.

[0025] The power consumption management method according to the first aspect of the present invention is used for a micro control unit, and the method includes but is not limited to steps S100 to S400: Step S100, obtaining the actual state of the micro control unit; Step S200: when the actual state is an idle state, determine the continuous idle time of the idle state; Step S300, determining a target sleep mode according to the continuous idle time and a plurality of preset different levels of sleep modes to be selected; Step S400: Switch the micro control unit to a target sleep mode.

[0026] In step S100 of the embodiment of the present invention, the actual state of the micro control unit includes a running state and an idle state. In the micro control unit, there are usually multiple tasks or threads running at the same time, and the task execution state of these tasks can be monitored to determine whether the micro control unit is in an idle state. If all tasks have been completed and there is no new task to be executed, it can be considered that the micro control unit is in an idle state, otherwise it is in a running state.

[0027] If the microcontroller unit needs to respond to external events (such as sensor data acquisition, communication data processing, etc.), it can be determined whether the microcontroller unit is in an idle state by monitoring the external event triggering state of the external event. When there is no external event to be processed, the microcontroller unit can be considered to be in an idle state, otherwise it is in a running state.

[0028] It is also possible to determine whether the micro control unit is in an idle state by monitoring the timer state. If the timer is not running or the timer has reached a preset time, it can be considered that the micro control unit is in an idle state, otherwise it is in a running state.

[0029] In some embodiments of the present invention, the actual state of the microcontroller unit can be determined by any one of the task execution state, the external event trigger state and the timer state alone, or the task execution state, the external event trigger state and the timer state can be combined to determine the actual state of the microcontroller unit. Specifically, when any one of the task execution state, the external event trigger state and the timer state indicates that the actual state of the microcontroller unit is the running state, the actual state of the microcontroller unit is determined to be the running state; when the task execution state, the external event trigger state and the timer state all indicate that the actual state of the microcontroller unit is the idle state, the actual state of the microcontroller unit is determined to be the idle state.

[0030] It should be noted that how to determine the actual state of the microcontroller unit by combining the task execution state, external event trigger state and timer state can be changed according to actual conditions, and the determination method exemplified in the embodiment of the present invention cannot be regarded as a limitation of the present invention.

[0031] The idle state determination method of the embodiment of the present invention is highly flexible, and can monitor the power consumption of each component of the system, optimize the modules or components with large power consumption in a targeted manner, design corresponding energy-saving management strategies for different application scenarios, and take different power consumption optimization measures according to actual usage. For example, if the power consumption of an external event is large, it can be determined whether the microcontroller unit is in an idle state based on the external event trigger state, and then the continuous idle time of the idle state can be determined, and then the target sleep mode can be determined based on the continuous idle time and the preset multiple different levels of sleep modes to be selected.

[0032] In step S200 of the embodiment of the present invention, the continuous idle time can be monitored by a timer. When it is detected that the actual state of the micro control unit is an idle state, the timer is started and starts timing, and the cumulative time calculated by the timer is the continuous idle time. During the timer timing process, if a trigger event occurs, indicating that the actual state of the micro control unit has been converted to a running state, the count value of the timer is cleared and the counting is restarted; if a keep-alive event occurs, the count value of the timer is cleared and the counting is stopped, and the timer is restarted and counted after the keep-alive event is exited.

[0033] In step S300 of the embodiment of the present invention, the sleep degree of the microcontroller unit is gradually increased according to the length of the continuous idle time. Multiple levels of sleep modes to be selected can be set, such as: low power mode, standby mode and deep sleep mode, each level corresponds to a different power consumption level, when the continuous idle time is short, a sleep mode with lower power consumption is selected, when the continuous idle time is long, it is gradually switched to a deeper sleep mode to reduce power consumption. Each level of sleep mode to be selected can also correspond to different times required to restore the microcontroller unit to the operating state, when the continuous idle time is short, a sleep mode that can quickly restore the microcontroller unit to the operating state is selected, when the continuous idle time is long, a sleep mode that is relatively slow to restore the microcontroller unit to the operating state is selected.

[0034] It should be noted that multiple levels of sleep modes to be selected may also correspond to other actions required by the microcontroller unit after entering the sleep mode. The specific actions can be obtained by analyzing the relationship between the continuous idle time and the different sleep modes to be selected based on actual conditions, and should not be regarded as a limitation of the present invention.

[0035] In addition, it should be noted that the specific sleep mode to be selected may also include more other sleep modes, which cannot be regarded as a limitation of the present invention.

[0036] In some embodiments of the present invention, after step S400 of the embodiment of the present invention, that is, after entering the target sleep mode, the sleep / wake-up mechanism is enabled to ensure the real-time performance of the system, monitor the wake-up trigger conditions, and wake up the microcontroller unit in time to achieve intermittent sleep of the microcontroller unit.

[0037] In some embodiments, the microcontroller unit can be awakened by an external event: the external event can be a trigger, a sensor, an input signal, or a state change of an external interrupt pin. When an external event occurs, the microcontroller unit can be awakened by a corresponding interrupt service program or an external interrupt and the corresponding task can be executed.

[0038] In other embodiments, the microcontroller unit can also be awakened by internal events: the internal event can be a timer overflow, a timer counter reaching a preset value, a hardware timer or a software timer reaching a specified time, etc. When an internal event occurs, the microcontroller unit can be awakened by a specific interrupt service program or timer interrupt and the corresponding task can be executed.

[0039] If the microcontroller is awakened by an external event, it is necessary to set the corresponding trigger conditions of the external interrupt pin or configure the parameters of the timer interrupt; if the microcontroller is awakened by an internal event, it is necessary to configure the timer counting method or the trigger conditions of the timer interrupt. When an external event or internal event occurs, the microcontroller will be awakened and execute the corresponding interrupt service program or jump to the instruction after awakening.

[0040] According to the power consumption management method of the embodiment of the present invention, by determining the continuous idle time of the idle state when the actual state of the microcontroller unit is the idle state, and setting different levels of sleep modes to be selected, the sleep mode to be selected of the corresponding level is selected as the target sleep mode according to the length of the continuous idle time, and finally the microcontroller unit is switched to the target sleep mode. Compared with the existing power consumption management method that only controls the sleep mode when the microcontroller unit is in the idle state, the power consumption management method of the embodiment of the present invention can adaptively select different levels of sleep modes to be selected according to the continuous idle time to reduce power consumption, has good flexibility, and can improve the stability and reliability of the microcontroller unit.

[0041] In some embodiments of the present invention, reference Figure 2 Step S300 specifically includes but is not limited to steps S310 to S320: Step S310, determining a target time threshold corresponding to each sleep mode to be selected; Step S320 : selecting one of the sleep modes to be selected from a plurality of different levels of sleep modes to be selected as a target sleep mode according to the continuous idle time and the target time thresholds corresponding to the sleep modes to be selected.

[0042] By directly setting the target time threshold corresponding to each sleep mode to be selected, multiple sleep modes to be selected can be graded. By comparing the continuous idle time and the size of each target time threshold, it is determined which level of sleep mode to be selected is reached, and the target sleep mode is determined. This can quickly determine the target sleep mode and improve the system response speed.

[0043] In some embodiments of the present invention, reference Figure 3 The target time threshold corresponding to each sleep mode to be selected is obtained through step S311 to step S312: Step S311, determining the power consumption level corresponding to each sleep mode to be selected; Step S312: setting a corresponding target time threshold according to the power consumption level of each sleep mode to be selected, wherein the corresponding target time threshold decreases as the power consumption level increases.

[0044] In some embodiments, multiple levels of sleep modes to be selected can be set, such as: low power mode, standby mode and deep sleep mode, each level corresponds to a different power consumption level, the power consumption of standby mode is lower than that of low power mode, but higher than that of deep sleep mode. When the continuous idle time is short, the sleep mode with lower power consumption is selected. When the continuous idle time is long, it is gradually switched to a deeper sleep mode to reduce power consumption, so that the degree of power consumption reduction of the microcontroller unit can be adaptively controlled. Compared with the existing power consumption management method that only controls sleep when the microcontroller unit is in an idle state, the power consumption management method of the embodiment of the present invention has good flexibility and can improve the stability and reliability of the microcontroller unit.

[0045] In some embodiments of the present invention, reference Figure 4 Step S320 specifically includes but is not limited to steps S321 to S322: Step S321, arranging the target time thresholds corresponding to the sleep modes to be selected in ascending order so that two adjacent target time thresholds form a sub-time interval, and the smallest target time threshold among the multiple target time thresholds and zero form a sub-time interval, so as to obtain multiple sub-time intervals corresponding to the multiple target time thresholds one by one; Step S322: If the continuous idle time is greater than the left endpoint value of the target time interval and less than or equal to the right endpoint value of the target time interval, the sleep mode to be selected corresponding to the right endpoint value of the target time interval is determined as the target sleep mode, wherein the target time interval is one of multiple sub-time intervals.

[0046] The target time thresholds corresponding to multiple sleep modes to be selected are arranged in order from small to large to form multiple sub-time intervals, which correspond to the relationship between the size of the continuous idle time and the levels of the multiple sleep modes to be selected. As the continuous idle time increases, by judging in which sub-time interval the continuous idle time falls, it is determined which sleep mode to be selected as the target sleep mode, which can improve the response speed of the system and quickly determine the target sleep mode.

[0047] In some embodiments of the present invention, the multiple sleep modes to be selected are respectively a first sleep mode, a second sleep mode and a third sleep mode, wherein the target time threshold corresponding to the first sleep mode is recorded as the first time threshold, the target time threshold corresponding to the second sleep mode is recorded as the second time threshold, and the target time threshold corresponding to the third sleep mode is recorded as the third time threshold, and the second time threshold is greater than the first time threshold and less than the third time threshold; According to the continuous idle time and the target time threshold corresponding to each sleep mode to be selected, one of the sleep modes to be selected at multiple levels is selected as the target sleep mode, including: If the continuous idle time is less than or equal to the first time threshold, determining the first sleep mode as the target sleep mode; If the continuous idle time is greater than the first time threshold and less than or equal to the second time threshold, determining the second sleep mode as the target sleep mode; If the continuous idle time is greater than the second time threshold and less than or equal to the third time threshold, the third sleep mode is determined as the target sleep mode.

[0048] In some embodiments, the first sleep mode is a low power mode, the second sleep mode is a standby mode, and the third sleep mode is a deep sleep mode. The power consumption of the standby mode is lower than that of the low power mode, but higher than that of the deep sleep mode. The first time threshold can be set to 5, the second time threshold can be set to 10, and the third time threshold can be set to 15. When the continuous idle time is less than or equal to 5, the microcontroller unit is controlled to switch to the low power mode; when the continuous idle time is greater than 5 and less than or equal to 10, the microcontroller unit is controlled to switch to the standby mode; when the continuous idle time is greater than 10 and less than or equal to 15, the microcontroller unit is controlled to switch to the deep sleep mode. When the continuous idle time is short, a sleep mode with lower power consumption is selected, and when the continuous idle time is long, it is gradually switched to a deeper sleep mode to reduce power consumption. Compared with the existing power consumption management method that only controls sleep when the microcontroller unit is in an idle state, the power consumption management method of the embodiment of the present invention can adaptively select different levels of sleep modes to be selected according to the continuous idle time to reduce power consumption, has good flexibility, and can improve the stability and reliability of the microcontroller unit.

[0049] It should be noted that the number of sleep modes to be selected, the specific sleep modes, and the specific size of the corresponding target time threshold mentioned in the above embodiments can all be changed according to actual needs and cannot be regarded as a limitation of the present invention.

[0050] In some embodiments of the present invention, reference Figure 5 , the actual state is obtained through step S110 to step S120: Step S110, obtaining the task execution status, external event triggering status and timer status of the micro control unit; Step S120: determining the actual state according to at least one of the task execution state, the external event triggering state and the timer state.

[0051] There are usually multiple tasks or threads running simultaneously in a microcontroller unit. The task execution status of these tasks can be monitored to determine whether the microcontroller unit is in an idle state. If all tasks have been completed and there are no new tasks to be executed, the microcontroller unit can be considered to be in an idle state, otherwise it is in a running state.

[0052] If the microcontroller unit needs to respond to external events (such as sensor data acquisition, communication data processing, etc.), it can be determined whether the microcontroller unit is in an idle state by monitoring the external event triggering state of the external event. When there is no external event to be processed, the microcontroller unit can be considered to be in an idle state, otherwise it is in a running state.

[0053] It is also possible to determine whether the micro control unit is in an idle state by monitoring the timer state. If the timer is not running or the timer has reached a preset time, it can be considered that the micro control unit is in an idle state, otherwise it is in a running state.

[0054] In some embodiments of the present invention, the actual state of the microcontroller unit can be determined by any one of the task execution state, the external event trigger state and the timer state alone, or the task execution state, the external event trigger state and the timer state can be combined to determine the actual state of the microcontroller unit. Specifically, when any one of the task execution state, the external event trigger state and the timer state indicates that the actual state of the microcontroller unit is the running state, the actual state of the microcontroller unit is determined to be the running state; when the task execution state, the external event trigger state and the timer state all indicate that the actual state of the microcontroller unit is the idle state, the actual state of the microcontroller unit is determined to be the idle state.

[0055] It should be noted that how to determine the actual state of the microcontroller unit by combining the task execution state, external event trigger state and timer state can be changed according to actual conditions, and the determination method exemplified in the embodiment of the present invention cannot be regarded as a limitation of the present invention.

[0056] The idle state determination method of the embodiment of the present invention is highly flexible, and can monitor the power consumption of each component of the system, optimize the modules or components with large power consumption in a targeted manner, design corresponding energy-saving management strategies for different application scenarios, and take different power consumption optimization measures according to actual usage. For example, if the power consumption of an external event is large, it can be determined whether the microcontroller unit is in an idle state based on the external event trigger state, and then the continuous idle time of the idle state can be determined, and then the target sleep mode can be determined based on the continuous idle time and the preset multiple different levels of sleep modes to be selected.

[0057] In some embodiments of the present invention, determining the actual state according to at least one of a task execution state, an external event triggering state, and a timer state includes: If the task execution status indicates that the task is not executed, the actual state is determined to be an idle state; If the external event trigger state indicates that it has been triggered, the actual state is determined to be the idle state; If the timer state indicates that the timer is not running or the timer has reached a preset time, the actual state is determined to be an idle state.

[0058] In some embodiments, there are usually multiple tasks or threads running simultaneously in the micro control unit, and the task execution status of these tasks can be monitored to determine whether the micro control unit is in an idle state. If all tasks have been completed and there are no new tasks to be executed, the micro control unit can be considered to be in an idle state, otherwise it is in a running state.

[0059] In other embodiments, if the microcontroller unit needs to respond to external events (such as sensor data collection, communication data processing, etc.), it can be determined whether the microcontroller unit is in an idle state by monitoring the external event triggering state of the external event. When there is no external event to be processed, the microcontroller unit can be considered to be in an idle state, otherwise it is in a running state.

[0060] In other embodiments, it is possible to determine whether the micro control unit is in an idle state by monitoring the timer state. If the timer is not running or the timer has reached a preset time, it can be considered that the micro control unit is in an idle state, otherwise it is in a running state.

[0061] In some embodiments of the present invention, the actual state of the microcontroller unit can be determined by any one of the task execution state, the external event trigger state and the timer state alone, or the task execution state, the external event trigger state and the timer state can be combined to determine the actual state of the microcontroller unit. Specifically, when any one of the task execution state, the external event trigger state and the timer state indicates that the actual state of the microcontroller unit is the running state, the actual state of the microcontroller unit is determined to be the running state; when the task execution state, the external event trigger state and the timer state all indicate that the actual state of the microcontroller unit is the idle state, the actual state of the microcontroller unit is determined to be the idle state.

[0062] In some embodiments of the present invention, the actual state of the microcontroller unit can be indicated by setting a working state flag. When the microcontroller unit is in the running state, the working state flag is "1", and when the microcontroller unit is in the idle state, the working state flag is "0", so that the system can quickly confirm the actual state of the microcontroller unit. Specifically, the task execution state of the task in the microcontroller unit can be monitored to determine whether the microcontroller unit is in the idle state. If all tasks have been completed and there are no new tasks to be executed, the microcontroller unit can be considered to be in the idle state, and the working state flag is set to "0"; otherwise, it is in the running state, and the working state flag is set to "1". It is also possible to determine whether the microcontroller unit is in the idle state by monitoring the external event triggering state of the external event. When there is no external event to be processed, the microcontroller unit can be considered to be in the idle state, and the working state flag is set to "0"; otherwise, it is in the running state, and the working state flag is set to "1". It is also possible to determine whether the microcontroller unit is in an idle state by monitoring the timer status. If the timer is not running or the timer has reached the preset time, the microcontroller unit can be considered to be in an idle state, and the working state flag is set to "0"; otherwise, it is in a running state, and the working state flag is set to "1".

[0063] In some embodiments, the power consumption management method of the embodiment of the present invention further includes but is not limited to the following steps: Initialize the power consumption monitoring module and low power consumption algorithm; Regularly monitor system tasks, obtain monitoring results, and monitor the resource status of the microcontroller unit; According to the monitoring results, determine whether it is necessary to trigger the low power mode (i.e., sleep mode). If necessary, when switching to the low power mode, turn off unnecessary modules or configure registers to reduce power consumption; After entering the low power mode, the sleep / wake-up mechanism is enabled to ensure the real-time performance of the system, monitor the wake-up trigger conditions, and wake up the microcontroller unit in time; Periodically optimize and adjust the power consumption of the microcontroller unit, and dynamically adjust the power consumption management strategy based on real-time monitoring results; Monitor abnormal situations (such as abnormal power consumption or system stability issues) and take corresponding preset processing measures according to the abnormal situations to ensure safe and stable operation of the system; When the microcontroller unit does not need to run, a shutdown operation is performed to further reduce power consumption, while ensuring safe shutdown and data preservation.
