摘　　要：为克服碟式太阳能间接跟踪光斑偏心问题,设计一种专门用于高强度光探测和光敏转换的太阳能跟踪传感器,对聚焦光斑进行直接跟踪。采用二级或者多级分隔的光导材料隔绝聚焦光斑的高温,光电传感器对比测量使聚焦光斑汇集到集热器中心,实现跟踪系统最大效率的利用太阳能。实验结果表明:传感器设计方法可行、可有效隔绝光斑的高温。通过Matlab分析每级光导材料光斑温度衰减系数为0.32,此传感器跟踪运行稳定,可提高跟踪精度。该研究为提高碟式太阳能自动跟踪精度提供一种方法。In order to overcome the problem of light spot deviate of the dish solar tracking indirectly , a solar tracking sensor used for high strength and light detection and photosensitive convert is designed. It can directly track the focusing spot. By using two or more separated optical materials to decay the high temperature of the light spot, the photoelectric sensor can make the focusing spot pack into the center of the collector by measurement and comparison, which achieves tracking system using solar energy efficiently. The experimental results show that this sensor design is feasible and can isolate the high temperature of spot. Attenuation coefficient of spot temperature of the optical material is 0.32 by Matlab. The sensor can work as designed and improve the tracking accuracy. The design puts forward a method of improving the accuracy of dish solar auto-tracking.
