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；红外避障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，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
With the development of science and technology, people’s quality of life has also been greatly improved, and people’s requirements for the quality and accuracy of daily necessities are getting higher and higher. In view of the current contact human temperature detection on the market, for example, many hospitals are still using mercury temperature measurement. Although the human temperature detection is more accurate, the mercury thermometer is accidentally broken, and the mercury vapor flowing out is harmful to people’s health and pollutes the environment. It is very important to design a safe, pollution-free, non-contact temperature measurement system.
This design takes STC89C52 single chip microcomputer as the core to design an infrared temperature measurement system. The system includes the minimum system of single chip microcomputer, infrared non-contact temperature measurement MLX90614, color detection circuit, etc. The non-contact temperature measurement MLX90614 is used to detect the temperature of the human body, and the color detection circuit detects whether to wear a mask; The infrared obstacle avoidance tube detects whether there is a person at present. The buzzer alarm is used to remind the current detector that the temperature is not within the normal range. The key can be used to carry out the normal temperature range of people at this time according to the specific situation. The display screen displays the current detected ambient temperature and human body detection temperature. Voice circuit: when someone is detected, the voice broadcast will tell whether the current detection temperature and current temperature are normal or too low; When the human body temperature exceeds the set threshold, an alarm will be sent to remind the user. The design is non-contact and safe to use.
Key words: Infrared tube alignment; Non contact infrared temperature measurement; Voice Announcements.
