摘要

为了使人们享受更加放松、安全、简易、实用的家居生活环境，本文建立了集人脸识别自动开门、室内CO浓度检测与处理、室内光照度检测与控制照明、室内温度检测显示、室内离人安防检测报警等功能于一体化的智能家居系统。通过建立TCP客户端与服务器进行相互通信，实现手机一键轻松出门、自动关门。采用基于STM32F765VI芯片的OpenMV摄像头，利用线性反投影算法计算采集到的人脸数据与人脸数据库进行对比，实现人脸识别自动开门。在系统不断运行时通过CO气体传感器、温度传感器、光照传感器、红外传感器、光电传感器等外部设备采集回的各种指标数据传输到MCU之中并利用编译好的程序进行相应处理，用以完成对应的检测与处理功能。最后通过搭载硬件模型对整个系统进行功能查验，实验结果表明基于STM32的智慧家庭系统能够准确地实现各项功能指标的监测。

Abstract

A smart home system is designed which can realize the functions of face recognition

automatic door opening

indoor CO concentration detection

indoor illumination detection

automatic control lighting

indoor temperature detection

indoor security detection and other functions. The purpose is to let people get safe and practical living environment at home. Through the establishment of WiFi communication

the mobile phone control door opening is realized. This design adopts the OpenMV camera based on STM32F765 chip as the main identification instrument. The linear back projection algorithm is used to calculate the collected face data and the calculation results are compared with the face database to realize the automatic door opening function. When the system is running continuously

the data collected by the external equipment such as CO gas sensor

temperature sensor

optical sensor

infrared sensor and photoelectric sensor are processed to complete the corresponding detection and processing functions. Finally

the whole system is checked by the hardware model. The experimental results show that the system runs smoothly and all the function indexes have been achieved. A more reliable smart home system is obtained.
