摘　　要：为了研究一种结构简单、成本低廉且跟踪精度高的太阳跟踪设备,设计了一种双轴跟踪控制系统,实现了太阳光照射方向的实时跟踪。系统以LM324为核心,采用两组光敏电阻,构建了一种光电传感器跟踪模式,通过光照强度不同而导致光敏电阻的阻值不同,采用桥式比较电路后,再通过起比较器作用的LM324来控制两台直流减速电机驱动双轴跟踪装置以便调整支架的位置,直到固定平面与太阳光垂直,获得最大的光照量,因而能大大提高太阳能的利用率。In order to study a kind of simple structure, low cost and high tracking precision sun tracking device, a two-axis tracking control system is designed, realizing the real-time tracking of the direction of the sun. LM324 is used as the core in this system, using two sets of photosensitive resistance, a model of photoelectric sensor tracking is constructed, through the different light intensity leads to the different resistance of photosensitive resistance, after using bridge type comparison circuit, again by LM324 used as comparator, controlling two DC gear motors to drive the two-axis tracking device, so as to adjust the position of the sup- porting set, until the fixed fiat is perpendicular with the sunlight, getting the most quantity of illumination, so it can greatly im- prove the utilization of solar energy.
