智能手环智能佩戴检测技术探究

Intelligent detection technology of smart bracelet

现有的智能穿戴设备如智能手表、智能手环等,若用户将智能手环放置在桌面上,手环会自动误检测为用户处于久坐或深度睡眠的状态,从而导致监测的睡眠数据不准确;与此同时,当手环处于非佩戴状态下,而放置在震动的场所,手环会自动计步,导致计步数据的不准确。针对以上问题,本文提出一种基于智能手环佩戴检测的全新电路与方法。通过容监测处理芯片与MCU对放置在手环底部采样的导电布电容传感器进行采样,并通过一定的检测算法,从而检测手环的佩戴状态,解决因为手环不能自动检测佩戴,而错误判断用户处于久坐或深度睡眠,或者误计步的现象。

The exfsting smart wearable devices such as smart watches, smart bracelet, smart bracelet if users will be placed on the desktop, the bracelet will automatic error detection for users in sedentary or deep sleep, resulting in sleep monitoring data is not accurate; at the same time, when the bracelet is in non-wear state, and placed in the vibration of places, the bracelet will automatically lead to the step by step, the data is not accurate; to solve this problem, this paper presents a new circuit and method based on the detection of the smart bracelet worn. To place the conductive cloth at the bottom of the bracelet in the capacitance sensor sampling sampled by volume monitoring processing chip and MCU, and the detection algorithm to detect the bracelet worn state, so as to solve the problem of automatic detection because of not wearing the bracelet, and the user is in the wrong judgment sitting or deep sleep; or false step phenomenon.
