基于嵌入式技术的追日随动系统设计

摘要

This article is designed a tracking servo system, using chip S3C6410A as the core control chip, using a biaxial servo as the executing agency, according to the sun’s trajectory parameters provided by authority observatory and local latitude, time information to calculate the elevation angle and azimuth of the sun, convert it into a pulse signal to control the servo rotation to ensure solar panels facing the sun. Realization of achieve human-computer interaction via the LCD touch screen and displays the current solar elevation angle, azimuth information and steering deflection current state. Through joint commissio-ning system, and the results show that the system has a good and stable performance to follow, can effec-tively improve the utilization of solar energy, with high practical value.%设计了以S3 C6410 A微处理器为核心控制芯片的追日随动系统，用双轴舵机作为执行机构，根据权威天文台提供的太阳轨迹参数和当地的纬度、时间信息计算出太阳的高度角和方位角，将其转换成脉冲信号控制舵机旋转，保证太阳能光伏板始终正对太阳。通过LCD触摸屏实现人机交互，并显示当前太阳高度角、方位角信息以及舵机当前的偏转状态。经过系统调试，实验结果显示该系统有着良好稳定的跟随性能，能有效提高太阳能的利用率，具有较高的实用价值。
