基于单片机的红外检测及WIFI模块系统设计(附原理图,实物图,程序代码)(课题说明书,开题报告,中期检查表,论文8500字)
摘 要 伴随着人们生活水平的提高，各种智能化设备渐渐成为了生活中的一部分，人们的防范意识也越来越低，而红外线防盗报警器扮演着重要的角色，给人们生活提供了安全保障。先是对周边进行监控，然后再进行报警是本系统的最终目的。系统可以实现的功能有：当有人出去的时候，根据报警系统的功能设定，可以用手机进行远程操控，通过WIFI模块，把它设置为布防这一状态，系统里面有个探测器，此时就运作起来，,当有人从外面进来时，系统里面的热释电红外传感器这个仪器立刻会起到作用，会探测到外面的动静，检测到人身体辐射出的红外光谱，并且能够把它转换成电信号，两者相对应，然后系统里面的红外热释电模块会接收到TTL 电平，紧接着把它传送到STC89C52单片机上，在STC89C52这个单片机上接受处理后，运行起来，报警电路就会发出警告，人们通过手机APP会收到消息，从而提高警惕。

Infrared Detection and Voice Response System Based on Single Chip Microcomputer
Abstract With the improvement of people's living standard, various intelligent equipments have gradually become a part of life, and people's awareness of prevention is getting lower and lower, while infrared anti-theft alarm plays an important role, providing security for people's lives. The ultimate goal of this system is to monitor the surrounding area first, and then to alarm. The functions of the system can be realized as follows: when someone goes out, according to the function setting of the alarm system, it can be set to the state of deployment and defense. There is a detector in the system, and it will work at this time. When someone comes in from outside, the pyroelectric infrared sensor in the system will immediately play a role, and will detect the external movement and body radiation. The infrared spectrum emitted can be converted into electrical signals, which correspond to each other. Then the infrared pyroelectric module in the system receives TTL level, and then transmits it to STC89C52 microcontroller. After being processed on STC89C52 microcontroller, the alarm circuit will give a warning, and people will receive messages to raise their vigilance.
