1、智能家居人脸监控和环境控制系统的设计与实现1摘要摘要随着我国社会经济的高速发展，社会面临的老龄化问题形势越发严峻， “空巢老人”数量的急剧增长也让社会矛盾越发凸显。如何保证老人独处在家时的安全，成为日益凸显的社会问题。本文设计了一套智能家居人脸监控和环境控制系统，系统通过视频捕捉的方法保障家庭环境，通过人脸识别的方法进行智能家庭监控、自动识别监控范围内的人脸，实现人脸识别门禁。当监测范围内出现陌生人脸或无人脸出现时，自动发送警报，通知人员尽快前往查看。此外，系统还能监测家庭的温度与湿度，针对室内有人、室内无人两种状态，设计两套不同的温湿度模式有人时将温湿度设定为人体最舒适范围，无人时将温湿度设
2、定为室内物体最佳存放范围。系统监测到的环境数值将即时显示在 LCD 屏上，若传感器监测数值超过原先设定的温湿度，系统将自动开启风扇及除湿机来降低环境温湿度；反之，若监测数值低于设定值，系统将自动关闭风扇及除湿机，使温湿度回升至最佳状态。此系统利用 arduino 芯片来做传感器数据的接收与处理，以树莓派为硬件载体，利用 face+云平台进行云端人脸检测识别结果存储，通过输出信号控制外部组件。系统通过 USB 接口作为借口与 PC 端进行通信，并完成数据的实时传输、监控和存储，最后建立环境变化趋势图。整个系统设计完整，功能丰富，针对当前“空巢老人”家庭独居频发的安全问题，提出了一种更为可靠的解决

4、y when they are alone at home has become an increasingly prominent social issue. This article has designed a set of smart home face monitoring and environmental control system. Through video capture, face recognition and other methods, the system automatically recognizes the face within the monitori
5、ng range and realizes face recognition access control. When a strange face or unfazed face appears in the monitoring area, an alarm is automatically sent and the personnel are notified to go to view as soon as possible. In addition, the system can also monitor the temperature according to the enviro
6、nment , and humidity of the home. Two sets of different temperature and humidity modes are designed for indoor and outdoor environments. When someone is in use, the temperature and humidity are set as the most comfortable range for the human body. The temperature and humidity are set to the best sto
7、rage range for indoor objects. The environmental value monitored by the system will be immediately displayed on the LCD screen. If the sensor monitoring value exceeds the previously set temperature and humidity, the system will automatically turn on the fan and dehumidifier to reduce the ambient tem
8、perature and humidity; otherwise, if the monitoring value is lower than the set value The system will automatically turn off the fan and the dehumidifier, so that the temperature and humidity will return to the best condition.This system uses the arduino chip to receive and process the sensor data.
9、The Raspberry Pi is used as the hardware carrier and the face+ cloud platform is used for face recognition. The external components are controlled by the output signal. The system can also transfer data to a computer via the USB interface for real-time monitoring and storage of data and establishing
10、 a trend map of environmental changes. The entire system is designed to be complete and feature-rich. It will provide a reliable solution to the problem of safe living alone for “empty nesters”.Key words: Empty-Nesters; Face Recognition; Cloud Platform; Sensor; Arduino智能家居人脸监控和环境控制系统的设计与实现3目录目录摘要.2A
