The system adopted active tracking,namely calculate the input angle of the tracking device in advance,the angle is correspondent to the sun position some moment.Photoelectric sensors react the sunlight that putting on different position of the platform, feedback electrical signal.Then single-chip applys the subprogram and sends out pulse to step motors according to the signals,can control the rotate angle and direction of the step motor. The mechanism has realized the automatic track to the sun, so that the trackers top flat board can be always vertical to the sunlight and arrive the furthest receiving energy.

系统采用主动式跟踪，即预先计算好对应于某时刻太阳位置的跟踪机构的输入角度，通过跟踪器上平台不同位置上摆放的光电传感器感受该太阳位置的光照，反馈回电信号，单片机根据该信号调用子程序发出脉冲对步进电动机的转动角度和方向进行控制，实现了机构对太阳的自动跟踪，使跟踪装置的上平台始终处于垂直于光照方向，达到了能量最大限度的接收。
