Abstract

This invention discloses a timing method, apparatus, device, and medium based on a unit timer. The method acquires a user timer, a unit timer for calculating unit durations for the user timer, and a calibration timer for calculating calibration durations for the unit timer. During the user timer's timing process using the unit timer, the calibration timer is triggered based on its calibration timing period. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period equals a preset trigger count, it triggers a restart of the unit timer. This causes the unit timer to be triggered earlier, reducing the error of the unit timer within the calibration timing period and improving its accuracy. Furthermore, this reduces the cumulative error of the user timer, improving its accuracy. Moreover, this method improves the accuracy of the user timer solely through the calibration timer, requiring minimal system resources.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0048] Example 1

[0049] Figure 1A This is a flowchart illustrating a timing method based on a unit timer according to Embodiment 1 of the present invention. This embodiment is applicable to situations where a user timer is timed using a unit timer. The method can be executed by a timing device based on a unit timer, which can be implemented in hardware and / or software. The method specifically includes the following steps:

[0050] S110, Obtain a user timer, a unit timer for calculating a unit duration for the user timer, and a calibration timer for calculating a calibration duration for the unit timer.

[0051] User timers can be used to time tasks that are about to be processed in a program. Specifically, a computer program can set corresponding user timers for each task to be processed according to actual task requirements, or set corresponding user timers for tasks that need to be executed cyclically for a set duration.

[0052] A unit timer can be a timer that cycles through time in units of a minimum timing interval. In this embodiment, the unit timer can be used as a timing unit of a user timer. The unit duration in the user timer is the duration calculated by the unit timer running once, i.e., the unit timing period of the unit timer. For example, the unit timing period of the unit timer can be 1ms.

[0053] The calibration timer can be a timer used to calibrate the unit timer; specifically, the calibration timer can be used to restart the unit timer. In this embodiment, the calibration period of the calibration timer can be set to a value much larger than the unit timer's unit timer period, and the calibration period of the calibration timer can be an integer multiple of the unit timer period. For example, the calibration period of the calibration timer can be 10ms.

[0054] like Figure 1B The diagram illustrates the timing periods of various timers, where the calibration timer has a calibration timing period of m milliseconds, the unit timer has a unit timing period of n milliseconds, and the user timer has a user timing period of X*n milliseconds.

[0055] S120. During the process of the user timer using the unit timer for timing, the calibration timer is triggered based on the calibration timing period of the calibration timer.

[0056] Specifically, during the timing process using a unit timer, when the unit timer is triggered, the user timer accumulates all the unit durations counted by the unit timer. For example, if the unit timer's unit timing period is 1ms, each time the unit timer triggers, the duration calculated by the user timer is increased by 1ms. In this embodiment, the duration to be calculated by the user timer can be much larger than the unit timer's unit timing period; for example, the duration to be calculated by the user timer may be 80ms.

[0057] In this embodiment, during the user timer's timing process using a unit timer, the unit timer is triggered cyclically to increase the cumulative count of the user timer by repeatedly calculating the unit duration. Simultaneously, the calibration timer can run cyclically according to its calibration timing cycle. Continuing with the previous example, the calibration timer can run once every 10ms, meaning each run calculates a duration of 10ms.

[0058] S130. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, then the unit timer is restarted so that the unit timer is triggered in advance.

[0059] Specifically, after the calibration timer is triggered, it can monitor the number of times the unit timer is triggered within the current calibration timing period. If the current number of triggers of the unit timer within the current calibration timing period is equal to the preset number of triggers, the calibration timer can immediately trigger the restart of the unit timer so that the unit timer is triggered in advance, that is, the unit timer is triggered again before the unit timing period has elapsed after being triggered.

[0060] In other words, after a unit timer is triggered, it calculates the duration of one unit timing period and triggers again after the duration calculation is complete. A calibration timer, however, can restart the unit timer immediately without waiting for it to calculate the duration of one unit timing period when the current trigger count is the preset trigger count, causing the unit timer to be triggered again. Since user timers calculate their cumulative duration based on the number of triggers of the unit timer, when the calibration timer restarts the unit timer, the user timer immediately adds one unit timing period to the accumulated duration.

[0061] For example, the calibration timing period is 10ms, and the unit timing period of the unit timer is 1ms. After the calibration timer is triggered, when the calibration timer detects that the unit timer has been triggered 9 times, that is, when the user timer determines that the cumulative calculation duration of the unit timer during the operation of the calibration timer is 9ms, the calibration timer immediately restarts the unit timer so that the number of triggers of the unit timer reaches 10 times. At this time, the cumulative duration calculated by the user timer is 10ms.

[0062] It should be noted that the purpose of using a calibration timer to trigger the restart of the unit timer in this embodiment is as follows: The time consumed by the unit timer's processing function may introduce errors into the calculated duration of a single run of the unit timer. For example, if the actual duration required for one run of the unit timer is 1.2ms, while its calculated duration is 1ms, the error per run is 0.2ms. Without calibration of the unit timer, the accumulated error of the user timer may become significant. Therefore, this embodiment uses a calibration timer to trigger the restart of the unit timer within a calibration period. This ensures that the unit timer is immediately restarted after a single trigger, and is triggered again after a single trigger, eliminating the need to calculate a full unit timer period. This reduces the accumulated error of the unit timer within a calibration period, thereby improving the accuracy of the unit timer.

[0063] In this embodiment, the preset trigger count can be a pre-set number of times to trigger a restart of the unit timer; the preset trigger count can be any value, but of course, it cannot exceed the ratio between the calibration timing period and the unit timing period. For example, the preset trigger count can be obtained by: determining the proportional relationship between the unit timing period of the unit timer and the calibration timing period; and determining the preset trigger count of the unit timer within the calibration timing period based on the proportional relationship.

[0064] The proportional relationship can be the ratio of the calibration timing period to the unit timing period, i.e., the multiple relationship between the standard timing period and the unit timing period. For example, the standard trigger count can be set based on the proportional relationship; for instance, the preset trigger count can be equal to the proportional relationship value minus 1. For example, if the calibration timing period is m milliseconds and the unit timing period is n milliseconds, then the preset trigger count can be... Where m is an integer multiple of n. That is, the preset trigger count can be the second to last trigger that the unit timer should trigger within one calibration timing period, without considering the running error of the unit timer.

[0065] Of course, the preset number of triggers can also be any one of the triggers of the unit timer within a calibration timing period. The calibration timer can trigger a restart of the unit timer once within a calibration timing period.

[0066] Specifically, during the user timer's timing process, the calibration timer can be triggered cyclically. In each calibration timing cycle, the unit timer is restarted once to reduce the cumulative error in each calibration timing cycle, thereby reducing the cumulative error during the user timer's timing period.

[0067] In this embodiment, the method may further include: during the process of the user timer using the unit timer for timing, determining the cumulative timing length corresponding to the unit timer based on the user timer; if the cumulative timing length reaches the reference timing length corresponding to the user timer, then triggering the processing function corresponding to the user timer.

[0068] The user timer can determine the cumulative timing length corresponding to the unit timer based on the number of times the unit timer is triggered. Specifically, each time the unit timer is triggered, the user timer can add the unit timer's unit timing period to the existing timing length. Each time the user timer accumulates a unit timing period, it can check whether the accumulated timing length has reached a reference timing length. The reference timing length can be a preset length that the user timer needs to keep track of. If it has, the corresponding processing function of the user timer is triggered. The processing function includes, but is not limited to, data processing tasks and application control tasks, such as refreshing the usage status of an application or restarting an application.

[0069] It should be noted that the reference timing length can be obtained from a preset user timer linked list. That is, optionally, the method further includes: obtaining the timer linked list of the user timer, wherein the timer linked list includes at least one timing length to be executed; and determining the reference timing length corresponding to the user timer based on the timer linked list.

[0070] The timer list can be a linked list used to store the durations of each pending execution time; these durations can be stored in the timer list in chronological order of execution time. Specifically, the duration closest to the execution time can be read from the timer list and used as the reference duration for the user timer.

[0071] For example, such as Figure 1C The diagram illustrates the timing process of a user timer. Specifically, after initializing the user timer's linked list, a unit timer can be triggered to start timing. The user timer increments the timing length of the unit timer. Furthermore, it checks whether the incremented timing length exceeds the reference timing length. If so, the user timer processing function is triggered.

[0072] The technical solution of this embodiment obtains a user timer, a unit timer for calculating the unit duration of the user timer, and a calibration timer for calculating the calibration duration of the unit timer. During the timing process of the user timer using the unit timer, the calibration timer is triggered based on the calibration timing period of the calibration timer. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, it triggers a restart of the unit timer to make the unit timer be triggered in advance, reducing the cumulative error of the unit timer within the calibration timing period, thereby improving the accuracy of the unit timer. Furthermore, it reduces the cumulative error of the user timer and improves the accuracy of the user timer, solving the technical problem of inaccurate timing of traditional timers. Moreover, this method can improve the accuracy of the user timer by calibrating the timer alone, and the system resources occupied are low.

[0073] Example 2

[0074] Figure 2A This is a flowchart illustrating a timing method based on a unit timer according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment can further adjust the unit timing period and / or the calibration timing period based on the actual total number of triggers of the unit timer during the calibration timing period. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here. See also... Figure 2A The timing method based on a unit timer provided in this embodiment includes the following steps:

[0075] S210, Obtain a user timer, a unit timer for calculating a unit duration for the user timer, and a calibration timer for calculating a calibration duration for the unit timer.

[0076] S220. During the process of the user timer using the unit timer for timing, the calibration timer is triggered based on the calibration timing period of the calibration timer.

[0077] S230. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, then the unit timer is restarted so that the unit timer is triggered in advance.

[0078] S240. If the calibration timer detects that the actual total number of triggers of the unit timer within the calibration timing period is not equal to the preset number of triggers, then the unit timing period of the unit timer and / or the calibration timing period are adjusted based on the actual total number of triggers and the preset number of triggers.

[0079] In this embodiment, the preset trigger count is equal to the ratio between the calibration timing period and the unit timing period minus 1. Specifically, if the actual total trigger count is not equal to the preset trigger count, it indicates that the cumulative error of the unit timer within one calibration timing period is large, and the unit timer cannot complete the preset trigger count within one calibration timing period. Therefore, by adjusting the unit timing period and / or the calibration timing period, the number of times the unit timer should run within one calibration timing period can be reduced, thereby reducing the cumulative error of the unit timer within one calibration timing period, so that the total number of times the unit timer is triggered within one calibration timing period can reach the preset trigger count.

[0080] Specifically, if the unit timing period is increased, the ratio of the calibration timing period to the unit timing period decreases, and the number of times the unit timer should run within one calibration timing period decreases; if the calibration timing period is decreased, the ratio of the calibration timing period to the unit timing period decreases, and the number of times the unit timer should run within one calibration timing period decreases.

[0081] In this embodiment, the unit timing period and / or calibration timing period can be adjusted based on the difference between the actual total number of triggers and the preset number of triggers. Alternatively, a prompt message indicating that adjustment is needed can be displayed on the screen, and the unit timing period and / or calibration timing period can be updated based on the user's adjustment.

[0082] Optionally, the method further includes: displaying the unit timing period of the unit timer, the calibration timing period, the actual total number of triggers, and the preset number of triggers on a display interface; obtaining adjustment operation information of the user on the display interface, and updating the unit timing period and / or the calibration timing period based on the adjustment operation information.

[0083] Specifically, when it is determined that the actual number of triggers is not equal to the preset number of triggers, the timing of the current user timer can be paused or terminated, and a prompt message can be displayed on the display interface to obtain the user's adjustment operation information on the display interface. Furthermore, after updating the unit timing period and / or calibration timing period according to the operation adjustment information, the timing of the user timer can be re-executed according to the updated unit timing period and calibration timing period.

[0084] Of course, in this embodiment, the unit timing period and / or the timing period can be adjusted and / or calibrated after the user timer completes a timing cycle or before the user timer starts timing, so that when the user timer is timing based on the unit timer next time, the error accuracy of the user timer can be controlled within the allowable range.

[0085] For example, such as Figure 2BThe diagram illustrates a periodic adjustment process. After the calibration timer is triggered, the unit timer can be restarted, and its processing function is triggered. After the calibration timer completes one count, the actual number of times the unit timer has been triggered during this period is obtained. It is then determined whether the actual number of triggers equals the standard number of triggers. If not, both the unit timer period and the calibration timer period are adjusted; otherwise, the time synchronization is successful. Of course, while the user timer is using the unit timer for timing, the calibration timer can be continuously triggered to continuously calibrate the unit timer.

[0086] The technical solution of this embodiment determines whether the actual total number of triggers of the unit timer within the calibration timing period is equal to the preset number of triggers. If not, the unit timing period and / or calibration timing period are adjusted according to the actual total number of triggers and the preset number of triggers to reduce the cumulative error of the unit timer within the calibration timing period. This ensures that the actual total number of triggers of the unit timer within the calibration timing period can reach the preset number of triggers, thus solving the technical problem of inaccurate timing of traditional timers.

[0087] Example 3

[0088] Figure 3A This is a flowchart illustrating a timing method based on a unit timer according to Embodiment 3 of the present invention. This embodiment, based on the above embodiments, provides an exemplary description of the process for determining the unit timing period and the calibration timing period. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here. See also... Figure 3A The timing method based on a unit timer provided in this embodiment includes the following steps:

[0089] S310, Obtain a user timer, a unit timer for calculating a unit duration for the user timer, and a calibration timer for calculating a calibration duration for the unit timer.

[0090] S320. Determine the average error duration generated by the unit timer running once, and obtain the maximum cumulative error generated by the unit timer during the calibration timer running once (pre-set).

[0091] Specifically, the average error duration can be the delay caused by the processing time of the unit timer's function. Theoretically, the timing of one run of the unit timer should be the unit timing period. However, due to the existence of the average error duration, the time required for one run of the unit timer may be equal to the sum of the unit timing period and the average error duration. For example, if the unit timing period is 1ms and the average error duration is 0.1ms, then the time required for one run of the unit timer is 1.1ms. For instance, the actual duration of multiple runs of the unit timer can be obtained, and then the average error duration can be calculated based on each actual duration and the unit timing period.

[0092] In this embodiment, the maximum cumulative error generated by the pre-set unit timer during one run of the calibration timer can be the maximum error generated by the unit timer within one calibration timing period.

[0093] S330. Based on the average error duration and the maximum cumulative error, determine the unit timing period of the unit timer and the calibration timing period of the calibration timer.

[0094] Specifically, based on the unit timer's unit timing period, calibration timing period, and average error duration, the simulated cumulative error of the unit timer within the calibration timing period can be calculated. The unit timing period and calibration timing period are set with the condition that the simulated cumulative error cannot exceed the maximum cumulative error.

[0095] For example, the unit timing period of the unit timer and the calibration timing period of the calibration timer can be determined by the following formulas:

[0096]

[0097] in, The cumulative simulation error is represented by ΔT, the average error duration is represented by m, the calibration timing period is n, and the unit timing period is m. This represents the expected number of times the unit timer will run within the calibration timing period, and y is the preset maximum cumulative error. Using the above formula, the unit timing period and calibration timing period can be set to satisfy the above conditions.

[0098] For example, such as Figure 3B The diagram illustrates the initialization process for the unit timer and calibration timer. Specifically, the unit timer and calibration timer can be initialized, and the unit timing period and calibration timing period can be set through the steps described above. The processing function for the calibration timer can then be configured, and the unit timer and calibration timer can be started.

[0099] S340. During the process of the user timer using the unit timer for timing, the calibration timer is triggered based on the calibration timing period of the calibration timer.

[0100] S350. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, then the unit timer is restarted so that the unit timer is triggered in advance.

[0101] The technical solution of this embodiment determines the average error duration of the unit timer and the maximum cumulative error that the unit timer can generate within a calibration timing period. By setting the unit timing period and the calibration timing period, the error generated by the unit timing period within a calibration timing period is controlled within an allowable range, thereby improving the positioning accuracy of the user timer.

[0102] Example 4

[0103] Figure 4 This is a schematic diagram of a timing device based on a unit timer provided in Embodiment 4 of the present invention. This embodiment is applicable to the situation where a user timer is timed by a unit timer. The device specifically includes: an acquisition module 410, a timing module 420, and a calibration module 430.

[0104] The acquisition module 410 is used to acquire a user timer, a unit timer for calculating a unit duration for the user timer, and a calibration timer for calculating a calibration duration for the unit timer;

[0105] The timing module 420 is used to trigger the calibration timer based on the calibration timing period of the calibration timer during the process of the user timer using the unit timer for timing.

[0106] The calibration module 430 is used to trigger a restart of the unit timer if the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, so that the unit timer is triggered in advance.

[0107] Optionally, the device further includes an adjustment module, which is used to adjust the unit timing period of the unit timer and / or the calibration timing period based on the actual total number of triggers and the preset number of triggers if the calibration timer detects that the actual total number of triggers of the unit timer within the calibration timing period is not equal to the preset number of triggers.

[0108] Optionally, the device further includes a period setting module, which is used to determine the average error duration generated by the unit timer running once; obtain the maximum cumulative error generated by the unit timer during the calibration timer running once (pre-set); and determine the unit timing period of the unit timer and the calibration timing period of the calibration timer based on the average error duration and the maximum cumulative error.

[0109] Optionally, the calibration module 430 is further configured to determine the proportional relationship between the unit timing period of the unit timer and the calibration timing period; and to determine the preset number of times the unit timer is triggered within the calibration timing period based on the proportional relationship.

[0110] Optionally, the timing module 420 is further configured to determine the cumulative timing length corresponding to the unit timer based on the user timer during the process of the user timer using the unit timer for timing; if the cumulative timing length reaches the reference timing length corresponding to the user timer, then trigger the processing function corresponding to the user timer.

[0111] Optionally, the timing module 420 is further configured to obtain a timer list of the user timer, wherein the timer list includes at least one timing length to be executed; and determine a reference timing length corresponding to the user timer based on the timer list.

[0112] Optionally, the adjustment module is further configured to display the unit timing period, the calibration timing period, the actual total number of triggers, and the preset number of triggers of the unit timer on the display interface; obtain the user's adjustment operation information on the display interface, and update the unit timing period and / or the calibration timing period based on the adjustment operation information.

[0113] In this embodiment, by acquiring a user timer, a unit timer for calculating the unit duration of the user timer, and a calibration timer for calculating the calibration duration of the unit timer, during the user timer's timing process using the unit timer, the calibration timer is triggered based on the calibration timing period of the calibration timer. If the calibration timer detects that the current trigger count of the unit timer within the calibration timing period is equal to the preset trigger count, it triggers a restart of the unit timer to make it be triggered earlier, reducing the cumulative error of the unit timer within the calibration timing period, thereby improving the accuracy of the unit timer. Furthermore, this reduces the cumulative error of the user timer, improving its accuracy and solving the technical problem of inaccurate timing by traditional timers. Moreover, this method can improve the accuracy of the user timer simply by calibrating the timer, and it consumes low system resources.

[0114] The timing device based on a unit timer provided in the embodiments of the present invention can execute the timing method based on a unit timer provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the execution method.
