婴幼儿睡眠监测系统设计与分析
|
摘要
针对婴幼儿睡眠状况的监测和辨识设计,提出一种单片机实现的睡眠监测系统。系统设计包括硬件和软件系统搭建。硬件系统包括MK60FX512VLQ15系统板、压力传感器、LCD显示屏等。软件系统实现了利用婴儿床上多个压力传感器采集的数据,通过重心位置算法求出婴幼儿所处的位置,及位置波动范围与变化频率。再通过所提识别算法对这三类参数的计算分析,识别出睡姿变化和睡眠情况,最终输出睡眠状态。与手环式睡眠监测设备相比,所提系统具有智能化、可视化及可扩展性的优势。
In order to realize the monitoring and recognizing of the infant's sleep quality, a sleep monitoring system based on a simple chip microcomputer is proposed, which correspondingly includes a hardware design and a software system. The hardware system is mainly constructed by a MK60 FX512 VLQ15 system board,pressure sensors and a LCD display. The key working process of the software system is to use the data collected from the pressure sensors placed on the crib, and then calculate the parameters values of location,fluctuation range and change frequency of location by the proposed gravity center algorithm. The identification algorithm distinguishes the infant's posture change and sleep patterns by calculating these three kinds of parameters. Finally, the rating of infants' sleep status is outputted. Compared with some wearable types of bracelet sleep monitoring facilities, the proposed system achieves the intellectualization, visualization and extendibility of information.
