教学楼智能化节能控制系统设计

Design of the intelligent and energy-saving academic building control system

针对教室电能浪费的情况,设计一种基于STM32的教学楼智能化节能控制系统。系统以STM32微控制器为核心,使用对射式光电开关检测教室的人数,采用硅光电池测量教室内的光照度,利用DS18B20温度传感器测量教室的温度;微控制器STM32获得教室内的人数、光照度和温度后,根据程序中设定的算法智能地控制教室内灯和风扇的运行;然后通过数据传输模块将教室内的各个信息发送到PC,从而能够实现对教室使用情况的集中监测。测试结果表明:系统能根据教室的实际情况,智能地控制教室内灯和风扇的运行,能够达到节约用电的目的,节能效果良好。

To solve the problem of the electricity waste in the classroom,an intelligent and energy-saving building control system based on STM32 is designed. The STM32 microcontroller was adopted as the core device. A correlation photoelectric switch was used to detect the occupants inside the classroom. The illumination was measured with a silicon photocell and the classroom temperature was monitored by DS18B20 temperature sensors. After collecting the number of occupants inside the classroom,the illumination and room temperature,the STM32 controlled the lights and fans running in the classroom intelligently through an algorithm set in the program. The information was conveyed to the PC through a data transmission module for monitoring of the classroom condition. The experimental result shows that the system can control the lights and fans running intelligently according to the circumstances of classrooms and have a good energy-saving effect.
