The timing time can be adjusted to the order of microseconds.
Further, the control device compares the current time of the watch with the updated standard time, and controls the movement to drive the watch hand shaft according to the comparison result so as to calibrate the position of the watch hand corresponding to the watch hand shaft. Specifically, whether the needle movement of the watch hand is accurate or not can be confirmed through a comparison result, when the needle movement of the watch hand is inaccurate, the control device controls the movement to drive the watch needle shaft to drive the watch hand to rotate so as to complete time calibration of the watch, after the calibration is completed, the shooting device shoots the image of the watch needle shaft again, namely shoots the image of the watch needle shaft again and obtains the current time corresponding to the image, the obtained current time is compared with the updated standard time, and when the current time is consistent with the updated standard time, the calibration is judged to be correct; and when the current time is not consistent with the updated standard time, judging that the calibration is incorrect, and acquiring the current time of the watch again for judgment until the current time is judged to be consistent with the updated standard time next time.
The step of controlling the movement to drive the pointer shaft according to the comparison result so as to calibrate the position of the pointer corresponding to the pointer shaft comprises the following steps:
and if the comparison result shows that the current time is slower than the updated standard time, increasing the rotation speed of the movement for driving the pointer shaft so as to calibrate the position of the pointer corresponding to the pointer shaft.
If the comparison result shows that the current time is faster than the updated standard time, the rotating speed of the movement driving the pointer shaft is reduced, or the movement is controlled to reversely drive the pointer shaft, so that the position of the pointer corresponding to the pointer shaft is calibrated.
Specifically, if the comparison result is that the current time is slower than the updated standard time, the rotation speed of the movement driving the pointer shaft is increased to calibrate the position of the pointer corresponding to the pointer shaft. For example, taking a light smart watch as an example, the test start time may be set to 12 points, the test completion time is set to 12 points and 10 minutes, that is, 12 points and 10 minutes are the updated standard time, and the current time is 12 points and 10 minutes according to the current time of the watch hand, it is determined that the current time is slower than the standard time, at this time, the speed at which the movement drives the watch hand shaft may be increased to increase the rotation frequency of the watch hand shaft, and the watch hand shaft is rotated to a position corresponding to the standard time, so as to complete time calibration.
Further, if the comparison result is that the current time is faster than the updated standard time, the rotation speed of the movement driving the pointer shaft is reduced, or the movement is controlled to reversely drive the pointer shaft, so that the position of the pointer corresponding to the pointer shaft is calibrated. For example, taking a light smart watch as an example, the test start time may be set to 12 points, the test completion time is set to 12 points and 10 minutes, that is, 12 points and 10 minutes are the updated standard time, and the current time is 12 points and 11 minutes according to the current time of the hands, it is determined that the current time is faster than the standard time, at this time, the movement may be controlled to reversely drive the hands shaft, so as to reversely rotate the hands shaft to a position corresponding to the standard time, that is, to change the hands shaft from the initial clockwise rotation to the counterclockwise rotation, thereby completing the time calibration. Or, when the current time is faster than the standard time, the speed of the movement driving the watch hand shaft is reduced to reduce the rotation frequency of the watch hand shaft, namely, time calibration can also be completed.
Further, when the comparison result is that the current time is consistent with the updated standard time, it is determined that the movement of the pointer is accurate, and the rotation parameters of the pointer shaft do not need to be adjusted, where the rotation parameters include a rotation frequency, a rotation direction, a rotation angle, and the like, and there is no limitation here.
Therefore, the technical scheme provided by the invention can adjust the driving parameters of the movement through the comparison result so as to adjust the position of the watch hand shaft, thereby realizing the automatic calibration and time adjustment of the watch.
Based on all the above embodiments, an embodiment of the present invention further provides a readable storage medium, where a time calibration program of a watch is stored on the readable storage medium, and when the time calibration program of the watch is executed by a processor, the steps of the time calibration method of the watch are implemented.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the specification and the drawings, or any other related technical fields directly or indirectly applied thereto under the conception of the present invention are included in the scope of the present invention.
