摘　　要：在简要介绍地日运行规律的基础上,确定了视日运动跟踪法的计算模型及跟踪装置的机械结构。采用FPGA芯片XC3S1500为处理器,以步进电机为执行机构,采用Verilog语言设计实现了高度角-方位角太阳跟踪系统。根据系统的要求建立了计时模块、太阳高度角方位角计算模块、日出日落时间计算模块和步进电机脉冲控制模块。通过实验测试该系统能够达到预期的性能指标,对提高太阳能的利用率具有重要的现实意义。The computational model of the sun tracking system and the mechanical structure of tracking devices are constructed based on the operating law between sun and moon is introduced. An altitude-azimuth sun tracking system was designed by Verilog and using FPGA as microprocessor, the step motor as the executing agency. The timing module, solar altitude and azimuth calculation module, sunrise and sunset time calculation module and step motor pulse control module were built according to the requirement of the system. Experiments show that the sun tracking system can achieve the expected performance index, and has a great practical value for improving the utilization of solar energy.
