摘　　要：太阳能追踪传感器的性能制约着太阳能跟踪装置的精度和跟踪范围。针对传统光筒式传感器测量范围小、稳定性差等缺点,设计了一种改进型光筒传感器。在室内对传感器的测量范围进行了测试,在室外测试了改进传感器的阈值对跟踪装置的影响。将日梭万年历所计算的太阳高度角和方位角作为参考值。经测试,在12:40~14:40这段时间内,两个传感器的跟踪误差都比较小,传统传感器一天内的平均跟踪误差约为改进传感器的2倍。同时改进传感器很好地解决了光筒高度和测量范围相互制约的问题。The performance of solar tracking sensors constrains the accuracy and tracking range of solar tracking devices. Aiming at the shortcomings such as small measurement range and poor stability of traditional light tube sensor,an improved light sensor is designed. The measurement range of the sensor is tested indoors,and the effect of the threshold of the improved sensor on the device is tested outdoors. The solar elevation angle and azimuth angle calculated by the Japanese shuttle calendar are used as reference values. Tested at 12： 40 ~ 14： 40,the two sensors are relatively small tracking error. The average tracking error of a conventional sensor is about twice that of an improved sensor. At the same time the problem of mutual restriction between the height of the light and the measurement range is well solved.
