DETAILED DESCRIPTION

[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0010] In the existing technology, when the system is in sleep mode and needs an accurate alarm (accurate to the second level), it cannot be woken up in time to process. For example, a countdown alarm can only be implemented by using the CPU Timer (high-precision timer mechanism) when the system remains awake, resulting in high system power consumption.

[0011] In order to solve at least the above technical problems, the present disclosure provides a method for realizing an alarm clock. According to the present disclosure, if the interval time of the alarm clock is less than or equal to a first preset value, a second-level timer interrupt in the real-time clock module is set according to the interval time; if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is 0, and the current time is at the whole minute level, then the minute-level alarm interrupt in the real-time clock module is set according to the interval time; if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is not 0, and the current time is not at the whole minute level, then the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module are set according to the interval time based on the type of the alarm clock. In this way, by combining the alarm_irq and timer_irq of the RTC module, the accurate wake-up of the second-level alarm clock can also be realized in the system sleep state, thereby realizing the second-level alarm clock while effectively reducing the system power consumption.

[0012] Hereinafter, the technical solution according to the present disclosure will be described with reference to specific embodiments and in conjunction with the accompanying drawings.

[0013] Figure 1 1 is a flow chart showing a method 100 for implementing an alarm clock according to an embodiment of the present disclosure. Figure 1 The method 100 includes the following steps 102 to 108.

[0014] In step 102, the current time, the interval time for the alarm, and the type of the alarm are obtained. The interval time is the interval time between the current time and the alarm.

[0015] In step 104, if the interval time is less than or equal to the first preset value, a second-level timer interrupt in the real-time clock module is set according to the interval time.

[0016] The first preset value is the maximum duration of the second-level timer interrupt. For example, the maximum duration of timer_irq in the RTC module provided by the HYM8563 chip is 255s, then the first preset value is 255s, assuming that the interruption time is 30s, then timer_irq can be set directly.

[0017] In step 106, if the interval time is greater than the first preset value, the modulus of the interval time and the second preset value is 0, and the current time is in the whole minute level, a minute-level alarm interrupt in the real-time clock module is set according to the interval time. The second preset value is one minute, i.e., 60 seconds.

[0018] For example, the current time is 10:10:00, which is at the minute level, the interval time is 10min, which is greater than the first preset value 255s, and the modulo result with 60s is 0, then alarm_irq can be set directly, and alarm_irq provides alarm interrupts for year, month, day, hour, and minute expiration.

[0019] In step 108, if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is not 0, and the current time is not an integer minute, then the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module are set according to the interval time based on the type of the alarm.

[0020] In some embodiments, if the alarm type is a precise type, the minute-level alarm interrupt in the real-time clock module is set according to the minute-level portion of the interval time. After being awakened by the minute-level alarm interrupt, the second-level timer interrupt in the real-time clock module is set according to the second-level portion of the interval time. In this way, through the cooperation of the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module, precise awakening of the second-level alarm can be achieved even in the system sleep state.

[0021] Precise alarms refer to those that must be woken up on time, such as the countdown set by the user, the exact clock set by the user. If the user sets the alarm at 8:00, it must be ensured that the alarm is woken up on time at 8:00 to notify the user. In this case, alarm_irq can be used to meet this requirement, as described in step 106. Assuming that the automatic page turning function on the electronic paper book device, the user sets the page turning timer to 10 seconds, it must be ensured that the page turning interval is 10 seconds. At this time, alarm_irq cannot meet the application requirements, and timer_irq is required to implement it, as described in step 104. Assuming that the countdown set by the user is 10min30s, which exceeds the first preset value, alarm_irq and timer_irq need to be implemented in coordination, that is, first set the alarm_irq wake-up of 10min, and then set the timer_irq wake-up of 30s, so that there is one more wake-up.

[0022] In some embodiments, if the type of the alarm clock is an imprecise type, and the alarm clock is an alarm clock with an automatic repeating interval, a new interval time is calculated based on the current time and the interval time. At least one of the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module is set according to the new interval time. In addition, after the alarm clock corresponding to the new interval time wakes up, the minute-level alarm interrupt in the real-time clock module is set according to the interval time, thereby obtaining an alarm clock with an automatic repeating interval. In this way, for an imprecise alarm clock and an alarm clock with an automatic repeating interval, the power consumption problem caused by the coordinated use of the minute-level alarm interrupt and the second-level timer interrupt can be optimized by calculating the new interval time, and while realizing the second-level alarm clock, the system power consumption is further reduced.

[0023] Inaccurate alarms refer to scenarios where precise wake-up is not required, such as when some applications update data at regular intervals and do not strictly require accuracy. For such alarms, the alarms can be aligned to the next minute. Inaccurate alarms also include alarms with automatic repeat intervals, such as when the system automatically updates the battery level at regular intervals.

[0024] In some embodiments, calculating a new interval time according to the current time and the interval time comprises using the following equation: ; Wherein, interval′ represents the new interval time, interval represents the interval time, now.tv_sec represents the current time, / / represents division and rounding, Indicates multiplication.

[0025] In some embodiments, at least one of the minute-level alarm interrupt and the second-level timer interrupt is set so that a new alarm of the whole minute level is obtained by adding the new interval time including at least one of the minute-level part and the second-level part to the current time. In addition, the minute-level alarm interrupt in the real-time clock module is set according to the new alarm.

[0026] In some embodiments, after being awakened by the minute-level alarm interrupt, the minute-level alarm interrupt in the real-time clock module is set again according to the interval time.

[0027] For example, continuing the above example, the system updates the power every 10 minutes. Assuming the current time is 10:00:30 and the interval is 10 minutes, the default alarm should be 10:10:30. However, if it is set directly, the minute-level alarm interrupt and the second-level timer interrupt will be used, resulting in two wake-up times. In order to further reduce power consumption, the new interval time is calculated. , so the new alarm time is 10:00:30+9m30s, which can round the default alarm to 10:10:00. When the next alarm comes at 10:10:00, now.tv_sec=10:10:00, and set the interval time to 10min again. There will be no seconds, and the driver can automatically wake up at 10min intervals.

[0028] In this way, the current time is added to the interval time, divided by 60s, and then multiplied, so that the alarm time can be rounded to minutes, so that only minute-level alarm interrupts are needed for subsequent wake-up, reducing system power consumption.

[0029] In some embodiments, if the alarm type is inaccurate and the alarm is a one-time wake-up alarm, the alarm is rounded to the whole minute level to obtain a new alarm. In addition, the minute-level alarm interrupt in the real-time clock module is set according to the new alarm.

[0030] Inaccurate alarm clocks also include one-time wake-up alarm clocks, such as waking up at a certain time every day. For this type of inaccurate alarm clock, simply round the alarm clock to the whole minute level and set the minute-level alarm interrupt in the real-time clock module according to the new alarm clock. Assuming there are two inaccurate alarm clocks: 10:10:30 and 10:09:30, then you can directly respond to both alarm clocks at 10:10:00.

[0031] In this way, for an inaccurate alarm that wakes up once, the alarm is directly rounded to the whole minute level, and the minute-level alarm interrupt in the real-time clock module is set according to the new alarm, thereby reducing system power consumption.

[0032] In some embodiments, the method 100 may also include: if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is 0, and the current time is not an integer minute level, and if the type of the alarm is an inexact type, then a new interval time is calculated based on the current time and the interval time. According to the new interval time, the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module are set so that the time of the adjusted alarm corresponding to the new interval time is an integer minute level. In addition, after the adjustment alarm wakes up, the minute-level alarm interrupt in the real-time clock module is set according to the interval time, thereby obtaining an alarm with an automatic repeating interval.

[0033] Hereinafter, the method and apparatus for implementing an alarm clock and application scenarios of an electronic device according to an embodiment of the present invention will be described by way of examples.

[0034] Figure 2 is a flow chart showing a method for implementing an alarm clock according to an embodiment of the present invention. Figure 2 The method includes the following steps 201 to 211.

[0035] In step 201, the current time, the interval time for the alarm, and the type of the alarm are obtained.

[0036] In step 202, if the interval time is less than or equal to a first preset value, a second-level timer interrupt in the real-time clock module is set according to the interval time. The first preset value is the maximum duration of the second-level timer interrupt.

[0037] In step 203, if the interval time is greater than the first preset value, the modulus of the interval time and the second preset value is 0, and the current time is a whole minute, a minute-level alarm interrupt in the real-time clock module is set according to the interval time. The second preset value is one minute.

[0038] In step 204, if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is not 0, and the current time is not an integer minute, then steps 205 to 211 are executed.

[0039] In step 205, if the alarm type is a precise type, a minute-level alarm interrupt in the real-time clock module is set according to the minute-level portion of the interval time.

[0040] In step 206, after being awakened by the minute-level alarm interrupt, a second-level timer interrupt in the real-time clock module is set according to the second-level part of the interval time.

[0041] In step 207, if the alarm type is non-precise and the alarm is an automatic repeating interval alarm, a new interval time is calculated according to the current time and the interval time, specifically: ; In the formula, interval′ represents the new interval time, interval represents the interval time, now.tv_sec represents the current time, / / represents division and rounding, Indicates multiplication.

[0042] In step 208, at least one of a minute-level alarm interrupt and a second-level timer interrupt in the real-time clock module is set according to the new interval time.

[0043] In some embodiments, a new alarm is obtained by adding the new interval time to the current time; and at least one of a minute-level alarm interrupt and a second-level timer interrupt in the real-time clock module is set according to the new alarm.

[0044] In step 209, after the alarm corresponding to the new interval time wakes up, the minute-level alarm interrupt in the real-time clock module is set according to the interval time, thereby obtaining an alarm with an automatic repeating interval.

[0045] In this embodiment, obtaining an alarm with an automatic repeating interval includes: after being awakened by a minute-level alarm interrupt, setting a minute-level alarm interrupt in a real-time clock module again according to the interval time.

[0046] In step 210, if the alarm type is inexact and the alarm is a one-time wake-up alarm, the alarm is rounded to the whole minute level to obtain a new alarm.

[0047] In step 211, a minute-level alarm interrupt in the real-time clock module is set according to the new alarm.

[0048] In some embodiments, the method may further include: if the interval time is greater than a first preset value, the modulo result of the interval time and the second preset value is 0, and the current time is not an integer minute level, and if the alarm type is an inaccurate type, then a new interval time is calculated based on the current time and the interval time. According to the new interval time, a minute-level alarm interrupt and a second-level timer interrupt in the real-time clock module are set, so that the time of the adjusted alarm corresponding to the new interval time is an integer minute level. In addition, after the adjustment alarm wakes up, a minute-level alarm interrupt in the real-time clock module is set according to the interval time, thereby obtaining an alarm with an automatically repeated interval.

[0050] According to another aspect of the present invention, Figure 4 3 is a block diagram showing an apparatus 300 for implementing an alarm clock according to an embodiment of the present invention. Figure 4 The device 300 for implementing an alarm clock includes a real-time clock module 302 and a control module 304 .

In addition, the control module 304 is configured to set the minute-level alarm interrupt and the second-level timer interrupt in the real-time clock module according to the interval time based on the type of the alarm if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is not 0, and the current time is not at the whole minute level.

[0056] In summary, the present invention provides a method and device for realizing an alarm clock, and an electronic device. If the interval time of the alarm clock is less than or equal to a first preset value, a second-level timer interrupt in the real-time clock module is set according to the interval time; if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is 0, and the current time is an integer minute level, a minute-level alarm clock interrupt in the real-time clock module is set according to the interval time; if the interval time is greater than the first preset value, the modulo result of the interval time and the second preset value is not 0, and the current time is not an integer minute level, then the minute-level alarm clock interrupt and the second-level timer interrupt in the real-time clock module are set according to the interval time based on the type of the alarm clock, so that by combining the alarm_irq and timer_irq of the RTC module in the system sleep state, the accurate wake-up of the second-level alarm clock can be realized, thereby realizing the second-level alarm clock and effectively reducing the system power consumption. In addition, for an inaccurate alarm clock and an alarm clock with an automatically repeated interval, the power consumption problem caused by the coordinated use of the minute-level alarm clock interrupt and the second-level timer interrupt can be optimized by calculating the new interval time, so that the second-level alarm clock can be realized while further reducing the system power consumption.
