摘  要

 面对能源危机、环境污染等问题，天然采光在现代建筑中越来越受到重视。目前，建筑采光的调节与控制措施一般分为固定遮阳和活动板遮阳采光，虽然活动遮阳设备有用手操作和机械控制两大类，前者广泛应用，但而由于其固定性以致没有更多的发展空间；而机械遮阳系统虽然容易操作，可昂贵的价格和高成本的安装费，使得该系统也没有广泛普及。
 随着科学技术的进步，人们对生活环境的要求也越来越高，因此，必须运用现代化的手段满足人们对光的要求。作为当代工业自动化重要支柱之一的可编程控制器S7—200，具有良好的可扩展性、指令功能强大、控制系统简单、价格低廉，可随时利用编程的方法灵活改变用户需求，实现因地制宜、因人而异的控制。本次研发的节能建筑采光控制系统将具有远距离的无线遥控的功能，而PLC的可靠性与灵活性更让此项研发具有现实的推广意义。

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.
