摘　　要：为提高太阳能利用装置的采光效率,设计了一种4级放坡四棱台光电传感器,分析了其跟踪范围和跟踪精度,并以此为基础设计了太阳跟踪系统的硬件部分和软件部分。试验结果表明:光电传感器粗跟踪装置的跟踪范围远远超过了一年当中方位角、高度角变化范围最大的夏季,能够满足对太阳在高度角和方位角大范围跟踪的需要。通过对软件流程的设计,采用5 min修正一次角度的循环方式,能够满足精跟踪装置跟踪精度的需求。通过光照强度对比试验,验证了太阳跟踪系统在粗、精两级跟踪模式下,太阳能利用装置的采光效率相比休眠模式采光效率提高了57.02%。该设计为太阳跟踪系统光电传感器跟踪范围的扩大和跟踪精度的提高提供了参考。To improve the lighting efficiency of solar energy utilization devices,a 4-stage sloping quadrangular prism photoelectric sensor was designed,and its tracking range and accuracy were analyzed.Based on this,the hardware and software parts of the solar tracking system were designed.The experimental results show that the tracking range of the photoelectric sensor coarse tracking device far exceeds the summer when the azimuth and altitude angles have the largest variation range in a year,and can meet the needs of tracking the sun in a wide range of altitude and azimuth angles.By designing the software process and adopting a 5-minute cycle of angle correction,it can meet the tracking accuracy requirements of the precision tracking device.Through comparative experiments of light intensity,it was verified that the daylighting efficiency of the solar energy utilization device in the coarse and fine tracking modes of the solar tracking system was 57.02%higher than that in the sleep mode.
