教室照明节能和自巡检系统的设计及应用

Design and Application of Classroom Lighting Energy Saving and Self Inspection System

教室照明节能和自巡检系统由arduino单片机主控系统、热释电红外传感器、光敏传感器、360度舵机构成。将检测器固定于舵机上,在教室屋顶中央进行全方位旋转扫描。根据对人体红外线、光线的检测结果,采用DBSCAN算法,得出人员较密集的区域,点亮该区域相应数量的灯具。若某处灯具出现故障,可以把其位置信息传送到维护人员的手机上,方便及时维修。此外,本照明系统搭配有两种照明模式(教师授课模式与学生自习模式),用来满足不同的照明需求。

The classroom lighting energy saving and self inspection system is composed of Arduino single chip microcomputer control system,pyroelectric infrared sensor,photosensitive sensor and 360 degree steering gear.Fix the detector on the steering gear,and carry out omni-directional rotation scanning in the center of the classroom roof.According to the infrared and light detection results of human body,DBSCAN algorithm is used to get the area with dense personnel and light up the corresponding number of lamps in this area.If a lamp fails,its location information can be transmitted to the mobile phone of the maintenance personnel for timely maintenance.In addition,the lighting system is equipped with two lighting modes(teacher teaching mode and student selfstudy mode)to meet different lighting needs.
