睡眠与疲劳监测类手表装置以及常态化小装置的监测方法Sleep and fatigue monitoring watch device and monitoring method for normalized small device

技术领域：Technical field:

本发明涉及睡眠与疲劳监测的方法和装置。The invention relates to a method and a device for monitoring sleep and fatigue.

背景技术：Background technique:

随着社会的发展与科技的进步，城市生活节奏加快工作压力增大，许多人存在不同程度的睡眠问题，常常感觉到困乏和疲劳，如果长时间得不到重视很可能会损害人体健康。对人体睡眠与疲劳状态的监测已经越来越引起现代医学的关注。对于一些特殊岗位的工作人员，例如飞行员和驾驶员等，他们的瞌睡和疲劳甚至会酿成重大事故，损害他人的安全和健康，因此必须要高度重视人的疲劳状态和睡眠状况。With the development of society and the advancement of science and technology, the pace of urban life is accelerating and work pressure is increasing. Many people have sleep problems of varying degrees, and often feel sleepy and tired. If they are not taken seriously for a long time, it may damage human health. The monitoring of human sleep and fatigue status has attracted more and more attention of modern medicine. For some staff in special positions, such as pilots and drivers, their drowsiness and fatigue may even lead to major accidents and damage the safety and health of others. Therefore, it is necessary to attach great importance to people's fatigue and sleep conditions.

另外，人的睡眠状况和疲劳状态会随着环境、时间、工作负荷等条件和因素不断发生变化，要想更准确地了解和掌握就必须要长时间连续监测，就需要一种能够随身携带的低功耗便携式设备，在不影响人们正常工作和生活的同时长时间全天候工作。In addition, people's sleep status and fatigue status will continue to change with conditions and factors such as environment, time, and workload. If you want to understand and master it more accurately, you must monitor it continuously for a long time, and you need a portable monitor. Portable devices with low power consumption can work around the clock for a long time without affecting people's normal work and life.

多导睡眠检测仪是现在最常用的睡眠检测手段，是国际公认的金标准，广泛应用于各大医疗院所。但是，因体积较大，人体传感器连接较多，连线复杂等原因只适合在医院病床上使用，使用地点环境受限，舒适度欠佳，无法用于日常睡眠与疲劳监测。Polysomnography is the most commonly used method of sleep detection, and it is an internationally recognized gold standard, widely used in major medical institutions. However, due to the large size, many human sensor connections, and complicated wiring, it is only suitable for use on hospital beds. The environment of the place of use is limited and the comfort is not good, so it cannot be used for daily sleep and fatigue monitoring.

为了解决多导睡眠检测仪成本高、消耗大、操作复杂、舒适度差等问题，人们研制了床垫式无干扰睡眠检测分析仪。仪器系统由单/多个床垫和床旁装置、传输线路、中央控制盒和计算机主机组成，使用过程中被测者只需躺卧在床垫上即可，无需黏贴电极，这大大提高了睡眠监测的舒适度，降低了操作的复杂度。目前该种方法专用于睡眠中心和实验室，服务于飞行员、驾驶员、运动员等特殊人员，也存在仪器体积大、不便携，使用环境受限等问题。In order to solve the problems of high cost, high consumption, complicated operation and poor comfort of polysomnography, people have developed a mattress-type non-interference sleep detection analyzer. The instrument system consists of single/multiple mattresses and bedside devices, transmission lines, central control box and computer host. During use, the subject only needs to lie on the mattress without sticking electrodes, which greatly improves It improves the comfort of sleep monitoring and reduces the complexity of operation. At present, this method is exclusively used in sleep centers and laboratories, and serves special personnel such as pilots, drivers, athletes, etc., but there are also problems such as large instrument size, inportability, and limited use environment.

疲劳检测方面，目前常见的方法有脑电图测量、闪光融合频率、智力精神测验、动作变化测量。这些方法需要专门的仪器和设备才能实现，比如脑电图仪、电极，闪光频率仪、眼罩，智力精神测验问卷或软件，人体动作摄影机、标志发光物。In terms of fatigue detection, the current common methods include EEG measurement, flash fusion frequency, intelligence and mental test, and measurement of movement changes. These methods need special instruments and equipment to realize, such as electroencephalograph, electrodes, flash frequency meter, goggles, intellectual mental test questionnaire or software, human body action camera, and sign luminous objects.

现有的疲劳和睡眠监测仪器与方法普遍存在体积设备较大、使用环境条件受限等问题，均无法在人们正常工作生活条件下实现便携式长时间全天候的测量，无法满足日常监测与保健的要求。Existing fatigue and sleep monitoring instruments and methods generally have problems such as large equipment and limited environmental conditions, which cannot realize portable long-term all-weather measurement under people's normal working and living conditions, and cannot meet the requirements of daily monitoring and health care .

不间断通过贴身小装置监测皮阻、皮温、加速度、大气压并对原始数据进行存储；Continuously monitor skin resistance, skin temperature, acceleration, atmospheric pressure and store raw data through personal small devices;

对所测数据进行如下计算：分别计算每个时间点上的三维加速度、三维磁场、三维角速度的几何均值，公式如下Calculate the measured data as follows: Calculate the geometric mean of the three-dimensional acceleration, three-dimensional magnetic field, and three-dimensional angular velocity at each time point, the formula is as follows

XYZ三轴加速度几何均数：$Y_1=\sqrt{({\mathrm{Ax}}^2+{\mathrm{Ay}}^2+{\mathrm{Az}}^2)/3}$Geometric mean of XYZ three-axis acceleration:$Y_1=\sqrt{({\mathrm{Ax}}^2+{\mathrm{Ay}}^2+{\mathrm{Az}}^2)/3}$

XYZ三轴磁场几何均数：$Y_2=\sqrt{({\mathrm{Mx}}^2+{\mathrm{My}}^2+{\mathrm{Mz}}^2)/3}$XYZ three-axis magnetic field geometric mean:$Y_2=\sqrt{({\mathrm{Mx}}^2+{\mathrm{My}}^2+{\mathrm{Mz}}^2)/3}$

然后对上面三个指标按照各自的权重系数进行叠加得到加权几何均数；Then superimpose the above three indicators according to their respective weight coefficients to obtain the weighted geometric mean;

对计算结果进行如下判断：首先判断体温和皮阻数据是否在正常值范围内，从而判断疲劳检测装置是否佩戴正确；然后对单位时间内的加权几何均数Y进行积分，得到与单位时间内的活动量成正相关的判断指标，该指标与相应时间段内皮肤阻抗变化趋势共同判断人体疲劳，如果Y值和皮肤阻抗变化量都超过了阈值，则可以根据相关数值的大小得到疲劳程度分级；The calculation results are judged as follows: firstly judge whether the body temperature and skin resistance data are within the normal range, so as to judge whether the fatigue detection device is worn correctly; then integrate the weighted geometric mean Y per unit time to obtain the Activity volume is positively correlated with the judgment index, which is used to judge human fatigue together with the change trend of skin impedance in the corresponding time period. If the Y value and the change amount of skin impedance exceed the threshold, the fatigue degree can be graded according to the magnitude of the relevant value;
