Children struggle to fall asleep by themselves because of their physiological characteristics. Therefore, research has been carried on various devices (such as a smartphone) to assist in improving the sleep quality of children. However, all such devices need to be controlled by parents and do not have functions for monitoring the sleep environment.
In this paper, a smart sleep-lighting system that includes a sleep-lighting device and a smartphone dongle is developed to improve the sleep environment of children.
The temperature, humidity, and luminance of the sleep environment are monitored and analyzed by the sleep-lighting device to control multi-color light and audio components. The colored light emitted by the multi-color light can be adjusted to improve the sleep atmosphere. Also, the audio component can play white noise to induce sleep. In addition, parents can use a smartphone dongle with a multi-channel wireless communication method to monitor and control one or more lighting devices in different locations in real time.
For environmental monitoring, average difference between proposed device and commercial sensor from chamber setting temperature 15∘C to 35∘C was 0.588∘C ± 0.10∘C, and average error value of the humidity measurement was 0.74% at 40% ∼ 60% RH. Also, the manufactured sleep-lighting device shows good performance in multi-color light emission, and playing of white noise. As result, the smartphone connected to the proposed smartphone dongle enables monitoring and control of the proposed lighting device in a wireless well.
The manufactured sleep-lighting device has a high-precision temperature and humidity sensor and a luminance sensor that can accurately monitor the sleeping environment. The lighting device can play white noise to induce sleep in children. Also, a multi-color LED light is operated via a smartphone application to improve the sleep atmosphere. The measured data will be sent to the lighting device and processed together with sleep environment data in order to improve the sleep quality. Additionally, the final system will be tested for real end-users with clinical experiments by sleep research center of a university hospital.
由于生理特征，儿童难以自行入睡。因此，人们对各种设备（如智能手机）进行了研究，以帮助改善儿童的睡眠质量。然而，所有这些设备都需要由家长控制，且不具备监测睡眠环境的功能。
本文开发了一种智能睡眠照明系统，该系统包括一个睡眠照明设备和一个智能手机加密狗，以改善儿童的睡眠环境。
睡眠照明设备对睡眠环境的温度、湿度和亮度进行监测和分析，以控制多色光和音频组件。多色光发出的彩色光可进行调节，以改善睡眠氛围。此外，音频组件可播放白噪声以诱导睡眠。此外，家长可以使用具有多通道无线通信方式的智能手机加密狗，实时监测和控制不同位置的一个或多个照明设备。
对于环境监测，在试验箱设定温度从15∘C到35∘C的情况下，所提出的设备与商用传感器之间的平均温差为0.588∘C±0.10∘C，在40%∼60%相对湿度下湿度测量的平均误差值为0.74%。此外，所制造的睡眠照明设备在多色光发射和白噪声播放方面表现良好。结果，连接到所提出的智能手机加密狗的智能手机能够很好地无线监测和控制所提出的照明设备。
所制造的睡眠照明设备具有高精度的温度、湿度传感器和亮度传感器，能够准确监测睡眠环境。该照明设备可以播放白噪声以诱导儿童睡眠。此外，通过智能手机应用程序操作多色LED灯以改善睡眠氛围。测量数据将被发送到照明设备，并与睡眠环境数据一起进行处理，以提高睡眠质量。此外，最终系统将由大学医院的睡眠研究中心进行临床实验，以测试真实的最终用户。
