摘要
为提高光纤导光照明装置的太阳光利用率,文章以L298N为电机驱动芯片,采用光电耦合器实现信号隔离,设计了一种基于C8051F063的太阳跟踪系统。该太阳跟踪系统避免了电机对控制电路的干扰,并通过检测太阳光强度选择不同的太阳跟踪方式,避免阴天时能耗高、效率低的不足。通过PWM驱动方位角和俯仰角电机,实现太阳跟踪的高精度控制。该设计简化了外围电路,具有成本低、跟踪的精度和效率高及实用性强等优势。
In order to improve the utilization rate of sunlight in optical fiber lighting device,this paper designs a solar tracking system based on c8051 f063,which takes L298 N as the motor driving chip and uses the optoelectronic coupler to achieve signal isolation.The solar tracking system avoids the interference of the motor to the control circuit and selects different solar tracking methods by detecting the sunlight intensity,so as to avoid the deficiency of high energy consumption and low efficiency in cloudy days.The high precision control of solar tracking is realized by driving the motor of azimuth and pitch angle with PWM.This design simplifies the peripheral circuit,and has the advantages of low cost,high tracking accuracy and efficiency,and strong practicability.
