摘　　要：太阳辐照度的地面测量精度除受辐射计的测量精度影响外,还受太阳跟踪转台精度的影响;为了推广不同区域太阳辐照度的测量,实现高精度地面辐照度的长期准确测量,文中结合硅光电池跟踪结构和视日运行轨迹程序跟踪方法,设计了每天能定时开关机工作,能适应有云气候的全天候、高精度、全自动控制的太阳跟踪转台,满足了该仪器用于野外观测站应用的要求;实验证明,该转台系统误差小于1‰,运行稳定,满足太阳辐照度高精度测量的要求。In addition to the solar radiometer＇ s accuracy, the accuracy of the rotating stage also affects the accuracy of the solar irradiance ground measurement. In order to archive and advance the precision measurement of solar irradianee, combines the＇photoelectric cell track and the depending on the sun running track, designs a new all--weather, high precision, automatic controlling sun tracking rotating stage, which can work in cloudy clays and work on time everyday, and meets the requirement of the observation station. The results show that this stage has no more than 1‰ systematic error, and has stable operation and can meet the requirements of the high accuracy solar irradiance measurement.
