基于51单片机实现的太阳能电池板转向系统设计 摘 要 太阳跟踪系统是针对太阳能空调、太阳能制氢、太阳辐照度测量、材料老化实验、高效太阳能光伏发电、高效太阳能热水器等需要对太阳进行实时跟踪的应用领域设计的、运动学、控制理论等学科体现，是当前国内外研究的热点问题之一。太阳能既是一次能源，又是可再生能源。它资源丰富，既可免费使用，又无需运输，对环境无任何污染。为人类创造了一种新的生活形态，使社会及人类进入一个节约能源减少污染的时代。具有两个自由度跟踪能力经过黑夜或阴天后，只要太阳一出即可跟踪工作可靠稳定。最后进行了系统联合调试，结果表明系统的软、硬件设计合理可行，为后续的研究工作奠定了基础。 关键词：光敏三极管 检测元件 比较器模块 单片机（AT89C52） 液晶显示屏（1602）All-weather Solar Tracking System ABSTRACT All-weather solar tracking system for solar air conditioning、Solar hydrogen production、Solar irradiance measurements、materials aging test、solar photovoltaic、 solar water heaters and other high need for solar applications in real-time tracking designed. Solar Tracking System is a comprehensive application of physics, optics, kinematics, control theory and other disciplines reflected, is the current hot topic of research at home and abroad. Solar is an energy, is renewable energy. It is rich in resources, both free, then no transport, no pollution on the environment. To create a new human life forms, and human society into a era of energy conservation to reduce pollution. So, all-weather track to realize the sun is to improve the use of solar energy, utilization of great significance。 The solar tracking system can be comprehensive tracking of the sun tracking capability, with two degrees of freedom. Through the night or cloudy days, the only one you can track the sun, reliable stability. ATMEL Corporation AT89C52 use of the system control chip, through the op amp device LM354N, LM358 module composed of relatively light on the photosensitive sensor resistance on the intensity and set the comparison reference voltage detection, and test results of logical operations, the responsible position angle and elevation angle of the stepping motor control, in order to achieve full-track the sun. 1602 LCD Module, Display System on the current work status and time. In the method described in detail the composition of the control system structure and working principle. The method uses nine photosens
