摘 要
伴随着科学技术的发展，人们的生活质量也得到大幅度的提升，人们对生活用品的质量和精度要求也越来越高。针对目前市面上都是接触式人体温度检测，比如现在很多医院还在使用水银测温，虽然对人体的温度检测较为准确，但是水银测温计不小心打破，流出来的汞蒸气对人们的身体有害，而且污染环境。设计一款安全的，没有污染的，非接触的测温系统就显得很重要了。
本设计以STC89C52单片机为核心设计的一款红外测温系统。该系统包括单片机最小系统、红外非接触测温MLX90614、颜色检测电路等，非接触测温MLX90614用来检测人体的温度、颜色检测电路检测是否佩戴口罩；红外对管检测当前是否有人，蜂鸣器报警用来提醒当前检测者的温度不在正常的范围内，按键可以根据具体情况进行人们此时正常的温度范围、显示屏显示当前检测的环境温度和人体的检测温度。语音电路，当检测到有人且计时3s后，语音播报当前检测温度及当前温度是否正常或者过高过低；当人体温度超过设定的阈值的时候进行报警提醒，而且该设计是非接触的,使用较为安全。

Abstract
as early as the 1980s, the concept of smart home was put forward. With the vigorous development of science and technology in the 21st century, the smart home industry has entered a period of rapid development. People’s busy working state and the pursuit of laziness promote the hot pursuit of smart home system. Smart home system based on different chips makes the price different. To solve this problem, the use of smart home system based on raspberry pie can make the cost cheaper and more acceptable to the public.
The purpose of this project is to study the control and implementation of a furniture system based on raspberry pie. The whole smart home system is composed of raspberry pie main control terminal, WEMOS D1 sub control terminal, voice module, relay group module, infrared decoding and transmitting module, camera module, alarm module and Android mobile phone. Through analyzing the instructions sent by raspberry party voice module or Android mobile phone, the control of four room lights and household appliances in the home is realized. The access control system adopts face recognition mode, and the flame sensor monitors the home environment in real time, so as to achieve a comfortable home environment and facilitate the life of modern people.
