基于ARM单片机的室内光控节能系统设计(任务书,开题报告,外文翻译,论文12000字)
摘要
随着社会和经济水平的发展，智能住宅的快速发展，照明系统的智能化发展引起了社会各界的广泛关注。
在本文中，设计并实施了室内光控节能系统系统，设计利用单片机进行识别光照强度这个外部信号，并通过单片机控制百叶窗窗帘的开合，开合窗帘通过步进电机进行调节，当室外天气晴朗，光强过大时将百叶窗调低一定程度的开合度，实现自然光照明；当没有阳光即光强度不足时，百叶窗的开合度调大一定程度；当自然光照度明显达不到正常工作照度时，且窗帘百叶已开到最大时，打开室内照明灯组，以维持正常工作照度。
通过设计和实验调试完成了基于ARM单片机的室内光控节能系统系统。其中光照传感器选取了GY-30传感器，采用步进电机来控制系统硬件，按键电路设定光照的阈值。

Abstract
With the development of social and economic levels, the rapid development of smart homes and the intelligent development of lighting systems have attracted widespread attention from all walks of life. [来源：http://www.doc163.com]
In this paper,I design and implementation of Intelligent light control energy-saving lighting system.Single-chip microcomputer is used to collect the external weather signal, and the shutter is opened and closed by the single-chip microcomputer. The opening and closing curtains are adjusted by the stepping motor,when the outside is sunny and the light intensity is too large, the degree of opening and closing of the blinds is lowered to a certain degree to achieve natural light illumination;when there is no sunlight, that is, the light intensity is insufficient, the degree of opening and closing of the shutter is adjusted to a certain degree;when the natural light illuminance obviously fails to reach the normal working illuminance, and the curtain louvers have been opened to the maximum, the indoor lighting group is turned on to maintain the normal working illuminance.
Through design and experiment debugging, the indoor light control energy-saving system based on ARM single-chip microcomputer was completed.Among them, the light sensor adopts GY-30 light illumination sensor, the control hardware adopts stepper motor, and the key circuit sets the threshold of illumination.
