摘要
针对多媒体教室使用过程中因环境光线配置不合理而影响教学效果以及过度照明造成能源浪费等问题,设计了一种适用于多媒体教室的智能用电管控系统。该系使用STC15W4K32S4单片机作为控制核心,可根据投影仪的使用情况、教室内人员分布情况以及教室内不同区域的光线强度,自动的控制教室总电源通断、电动窗帘开合以及各区域LED灯亮度。在教室中实际测试表明,该系统能够达到所需的效果,可提升多媒体教学的便利性、效果以及电能的利用率,具有一定的实用价值。
Aiming at the problems of the influence of teaching effect that is affected by the unreasonable allocation of environment light and the energy wasting caused by excess illumination when using multimedia classroom, this paper designes an intelligent system to control electricity usage in classroom. It's hardware uses the type of STC15W4K32S4 MCU as control center, can intelligently control the electric curtain's opening and closing, master switch of classroom on and off and the brightness of LED by the usage of the projector, the condition of people distribution in classroom and the light intensity in different areas. The test result in classroom shows that the system achieves the expected effect, can improve the convenience of multimedia teaching and save energy, so it has some practical value.
