基于单片机的教室节能控制系统设计

基于单片机的教室节能控制系统设计(论文14000字,外文翻译,答辩PPT)
摘要：在现阶段，资源节约已经成为了一个重要的社会问题，但是我国在各个场所却普遍存在着严重的电能资源浪费的现象，这需要我们运用现代先进的科学技术对现有的资源系统进行升级和改造。本设计基于STC89C52单片机设计了一个系统，该系统可以根据室内的人数来控制教室内亮灯的个数，做到无人不亮灯，有人适量亮灯，达到节能减排的目的。同时可以通过显示屏显示室内的人数，可以作为上课的点名系统来使用，可以帮助老师准确掌握上课学生人数，节省点名时间，有利于提高老师的教学效率。本设计还加了一个温湿度传感器，实时测量室内温湿度并通过LCD显示屏反馈给教室内的人，使用了若干LED灯来表示室内灯的个数，在实际应用时可以根据具体情况进行运用，达到节能减排的作用。

Design of the Energy-saving Control System based on  MCU
Abstract : At present, resource conservation has become an importent social problem. But each place of our country exists serious energy resource waste phenomenon, which need us to use the advanced science and technology to upgrade and reform the existing resource system, this design created a energy saving control system based on STC89C52 microcontroller, which can control the number of bright lights in the classroom based on the number of people in the classroom, when nobody is in the classroom, no light will be turned on. And turn on the lights based on the number of people which can achieve the purpose of energy saving and emission reduction. Meanwhile, the display screen can display the number of people in the room, which can be uesd as a student’s nomination system to help the teachers accurately determine the number of students in class, save time and improve the teaching efficiency.  The design also adds a temperature and humidity sensor which can measure indoor temperature and humidity real time and display them by the display screen, this design uses a number of LED lights to indicate the number of indoor lights, in application, it can be used according to specific conditions to save energy and reduct emission.
Key words : infrared sensor, energy saving, temperature and humidity sensor, MCU, people counting
