Abstract
Face energy crisis, environmental pollution, natural light in the modern building came under more and more attention. Currently, the regulation and control measure of the architectural lighting are generally divided into fixed and activities board light shade, although the activities are be divided into hand operation and mechanical control, the former was widely used, but rather because of its fixity so that there are no more development spaces; though, the mechanical sunshade system is easy to operate, the price is expensive and the cost of installation is high, that lead to the system hard to spread widely.
With the progress in science and technology, people’s requirements on living environment are increasing highly, therefore, we must use the modern means to meet the requirements of people on light. As one of the important pillars in modern industrial automation, the programmable logic controller S7-200 has good scalability, powerful instruction, low price and its control system is simple, also you can use the programming method to change the user’s needs of the local conditions, to achieve local conditions, vary the control. The development of the energy efficient building lighting control system will have long-distance functions of wireless remote control, while the PLC's reliability and flexibility make this dexelopment the promotion of practical significance.
