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.
