基于FPGA的家庭睡眠控制系统的设计(论文13000字)
摘要：根据调查显示，我国成年人失眠发生率接近三分之一，大约有4亿多人的睡眠质量有待提升。健康睡眠越来越受到人们的重视，由此带动了智能家居睡眠系统产业的发展。目前市场上的睡眠产品大多比较单一，效果也不理想，而随着FPGA技术成熟应用到社会各个领域，它的兼容性，可靠性，资源丰富等优点得到了很好的体现。这使得FPGA成为智能家居睡眠系统控制的核心成为可能。基于此背景，本文设计了一种以FPGA为核心的智能家居睡眠控制系统。该系统是通过检测用户的心率数值，经过FPGA内部资源处理，再将处理好的控制信息通过ZigBee无线通信系统发送出去，利用ZigBee无线模块来控制灯光，温控，窗帘，音乐等模块来实现整体的功能。可实时的显示睡眠环境的温度和使用者的心率，并根据心率值来判断使用者的睡眠状态，调节室内灯光，温度，控制窗帘，播放睡眠音乐，最终帮助用户舒适地入睡，提高用户的睡眠质量。

The Family Sleep Control System Based on FPGA
Abstract：According to the survey, the incidence of insomnia among adults in China is close to 33 percent. The sleep quality of more than 400 million people needs to be improved. Healthy sleep has attracted more and more attention, which has led to the development of smart home sleep system industry. Most of the sleeping products on the market are relatively single, and the effect is not ideal, nowadays. With the mature application of the technology of FPGA in various fields of society, its compatibility, reliability, rich resources and other advantages have been well reflected, which makes it possible for the FPGA to become the core of the control of smart home sleep system. Considering on this background, this paper designs a smart home sleep control system based on FPGA. The system detects the value of the user's heart rate, processes the internal resources of the FPGA, and sends the processed control information through the ZigBee wireless communication system, which uses the ZigBee wireless module to control the lighting, temperature control, curtain, music and other modules to achieve the overall function. It can display the temperature of the sleeping environment and the heart rate of the users in real time, and judge the sleeping state of the users according to the heart rate value, then adjust the indoor lighting, temperature, control curtains and play the sleeping music. Finally, it can help the users sleep comfortably and improve the sleeping quality of the users.
