Abstract

Embodiments of the invention provide a wearable device time calibration method and a wearable device to implement automatic correction of a local time of a wearable device. The method according to theembodiment of the invention includes the steps of acquiring a first standard time T1, and synchronizing a local time of the wearable device at the moment according to the T1; acquiring a second standard time T2, and calculating a difference (T2-t2) between the T2 and a local time t2 of the wearable device at the moment and a difference (T2-T1) between T2 and T1; when the (T2-t2) and the (T2-T1) satisfy a preset correction condition, calculating the compensation time corresponding to the T2 according to the (T2-t2) and the (T2-T1); and synchronizing the local time of the wearable device at themoment according to the T2, and after the T2, periodically correcting the local time of the wearable device according to the compensation time corresponding to the T2, so that the local time of the wearable device is consistent with the standard time.

Description

technical field [0001] The invention relates to the field of smart wearable devices, in particular to a method for calibrating the time of a wearable device and the wearable device. Background technique [0002] "Smart wearable device" is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, bracelets, clothing and shoes. [0003] With the development of smart wearable devices, they are closely related to people's lives and bring great convenience to people's lives. Especially for the recording of data, such as steps, calories, alarm clock reminders, etc., and these data generally need to be combined with time recording. The time on the current wearable device is obtained by the mobile phone to obtain the actual UTC, and then maintained by the local 32.768kHz clock. [0004] The existing solutions need to meet the conditions to ensure that the time of the wearable device ...
