【摘要】 太阳能以其安全、清洁、无污染、储量丰富等优点逐渐受到人们的关注。针对其密度低、光照方向变化等特点,发明了跟踪装置以提高太阳能的利用率。为了提高跟踪装置精度,降低制造成本,对现有视日运动轨迹式跟踪装置提出了改进方案。设计了一种新型跟踪装置,采用液压马达驱动液压绞车带动反射镜转动跟随太阳,避免了采用双液压缸驱动时所需要的复杂轨迹规划。利用单片机控制实现装置的自动运行,设计了完整的液压驱动方案,详细描述了其工作原理,通过MATLAB仿真验证了跟踪装置液压系统的可行性。更多还原

【Abstract】 In recent years,solar energy attracts people’s attention for its safety,cleanliness,pollution-free and rich reserves. Aiming at its low density,change of light direction and other characteristics,people invent a tracking device to improve the solar energy utilization. In order to improve the accuracy of tracking device and reduce the manufacturing cost,an improved scheme is proposed for the existing trajectory tracking device. We design a new tracking device. A hydraulic winch is driven by a hydraulic motor to drive a reflecting mirror to follow the sun,which avoids the complicated trajectory planning required when double hydraulic cylinders are adopted for driving. We use single-chip control to achieve the automatic operation of device. We design a complete hydraulic drive scheme and describe the principle in detail. Using the MATLAB simulation,we verify the feasibility of tracking device’s hydraulic system.更多还原
