【摘要】 在西部偏远的农村,阳光充足,太阳能要比电能更容易获得,农业用水可以采用太阳能抽水泵。介绍了一种自动追光控制系统,可以用它来辅助抽水泵的太阳能供电系统,控制步进电机去带动太阳能电池板自动旋转,使电池板能够保持在太阳能转换效率最高的位置,能够使太阳能抽水泵更加充分利用太阳能资源。更多还原

【Abstract】 In the western countryside,solar energy is sufficient,solar energy is obtained more easily than power.Agricultural water can use solar water pumps.An automatic tracking system which can automatically tracksolar is introduced in this paper.The system is used for pumps that have solar power supply systems,then the battery plate which is driven by the stepper motor can rotate according to the value of absorption power.Thus,the battery plate can be always in the position which is available to absorb maximum power.The solar energy water pump can use solar energy more fully by this system.更多还原
