摘　　要：介绍一种以三菱PLC(Q00J)为控制核心的极轴式太阳能自动跟踪系统,通过极轴运动抵消地球自转,实现太阳轨迹跟踪。系统采用时钟及光电传感器双级跟踪,以时钟跟踪为粗调,跟踪太阳理论位置防止光线偏差过大,以传感器跟踪为细调,跟踪太阳实际位置。能使太阳能电池板在晴天始终与太阳光保持垂直,阴雨天自动停止传感器跟踪,降低了系统硬件与运行成本,具有较高的实用价值。An auto polar axis sun tracking system with the core of Q series-Q00J made in Mitsubishi is presented.This system offsets the Earth's rotation by the movement of polar axis to achieve trajectory tracking of the sun.It combines the excellences of both clock control and sensor control.As the coarse tracking,clock control tracks the theoretical position of the sun to prevent the large deviation of the light.As the fine-tuning,sensor control tracks the physical location of the sun.The sun auto-tracker makes solar panel always vertical to the sun at sunny day,and it can turn off the sensor control at cloudy day.The device reduces the cost,and has great practical value.
