【摘要】 针对高校教室照明系统能耗大浪费多的问题,利用红外装置和人脸识别系统,设计了一套高校教室照明节能系统。系统将教室分为几个区域,利用红外装置周期扫描人体信号,能够实现无人自动关灯,并且在人员过于分散情况下,部分分区也会自动关灯,促使人员集中。该系统较好地解决了高校教室照明系统能耗大浪费多的问题,显著提高了电能的使用率。更多还原

【Abstract】 Aiming at the much waste of university classroom lighting system, a set of classroom lighting energy saving system was designed using infrared detection device and face recognition system. Classroom was divided into several regions. By scanning the signal of human body with infrared device periodically, the lights in the unmanned regions can be turned off automatically. And if students are too scattered, lights in some regions will also be turned off automatically to assemble the people. This system solved the problem of the much waste of university classroom lighting system and increased energy usage ratio significantly.更多还原
