摘要
针对现有太阳跟踪系统受天气影响大、稳定性不高等问题,设计了一种基于STM32F1的太阳跟踪系统。该系统以STM32F1为控制核心,通过电子罗盘模块和双模定位模块获取系统的位置姿态,当地坐标及时间。结合存储在系统内部的天文数据计算出系统所需调整的位姿参数,利用步进电机及编码器实现对太阳跟踪的闭环操作。通过测试,该系统具有反应灵敏,无需视觉,不受天气影响的特点。对提高太阳能利用率具有实用意义。
In view of the fact that the existing sun tracking system is greatly affected by the weather,and not so stable,a sun tracking system based on STM32F1 was designed.The system takes STM32F1 as the control core,and obtains the position and attitude,local coordinates and local time of the system through electronic compass module and dual-mode positioning module.Combined with the astronomical data stored in the system,the position and attitude parameters needed to be adjusted are calculated,and the closed-loop operation of sun tracking is realized by using stepping motor and coder.Through testing,the system has the characteristics of sensitive response,no need for vision,and is not affected by the weather.It is of practical significance to improve the utilization rate of solar energy.
