摘要
针对教学过程中使用投影时调整环境光线不便的问题,设计了一种适用于教室的智能电动窗帘控制系统。该系统硬件部分以STC12系列单片机为控制核心,用光敏元件捕获光线强度,继电器控制电灯总电源开合,与多媒体控制器相连,通过相应的程序,可捕获投影仪的使用情况,并据此结合采用不同的策略通过控制电机正反转调整窗帘的闭合程度达到自动调整室内光线的目的。测试结果表明该系统达到了预期效果,能够提高多媒体设备使用的便利性,具有一定的实用价值。
Aim at the problem of adjust inconveniently light when using projector in the course of teaching, this paper designed a control system of curtain apply to classroom. It's hardware used STC12 series MCU as control center, photosensitive element to capture light intensity, relay to control master switch of light, and connected with multimedia controller, through appropriate software, this system can capture condition of projector, then adjust classroom's light automatically by adjust the curtain's degree of opening by the way of controlling motor's rotation direction. The test result shows that the system achieves the design requirement, can improve the convenience of the use of multimedia, and has some practical value.
