摘 要
 在根本哈根气候会议上，低碳经济成为人类关注的热点，这意味着大幅度提高能源利用率，创建节约型社会将是未来21世纪经济创新的主要模式。具有节能降耗的自动化技术在全球提倡的“低碳经济”后越发成为人们关注的技术之一。自动化正以超快速度增长的趋势成为现代社会不可或缺的部分，也成为制造商快速服务全球市场的关键。能源问题与环境问题已经成为影响中国经济和谐发展的关键因素，实现节能减排已经成为新世纪我国社会发展的主要目标。
 这次的文档设计将PLC技术的安全可靠、操作方便等一系列优点应用在节能建筑采光系统上，通过设计硬件电路，根据系统要求编写软件程序，系统由无线遥控器发出相应按键指令来控制异步电机的转动，从而调整采光系统遮光板的角度。通过这样的控制设计，采光系统使用更加实用，操作简单，使用周期长，充分利用自然光能源，符合当前建设节约和谐型社会的基本要求。可以预见，PLC技术将在未来的社会发展、工业生产等领域都有着非常重要的意义。

Abstract
 In the climate conference in Copenhagen, the low-carbon economy has become the focus of attention of mankind, which means the increase of energy efficiency, creating a saving society will be the main mode of economic innovation in the future 21st century. With energy saving automation technology increasingly become one of the most concerned technologies after the global promotion of "low-carbon economy". Now automation is fast growing trend to be an indispensable part of modern society, which has also become a manufacturer of quick service key to the global market. Into the 21st century, as China's national economy and people's living standard sustained and rapid development, energy and environmental issues affecting the Chinese economy has become a key factor in the harmonious development and achieve energy conservation has become the new century the main objective of China's social development.
 The graduation will be designed the PLC technology’s safe , reliable, convenient operation to energy efficient building’s lighting systems, Through the design of hardware circuit, software program according to the system prepared in the system by a wireless remote control to issue the appropriate command buttons to control the rotational induction motor to adjust the lighting angle of light screen system. Through this control design, lighting systems use more practical, simple operation, long life cycle, take full advantage of natural light and energy saving building harmonious with the current basic requirements of society.. We can expect that PLC technology will be more important in the future social development, industrial production and other filelds.
