摘要
为了解决如何能更高效利用太阳能,通过观测太阳在空中的位置和对太阳运行轨迹进行科学分析,提出了通过运动模拟平台实现太阳运行位置的全面预测和重现的方法;在系统中,单片机根据输入日期算出太阳的高度角和方位角,并将其转换为驱动电机的脉冲数,以实现电机变频带动执行机构在不同时间段以不同速率运动使模拟光源到达预定位置的目的;同时通过编码器测量出电机实际脉冲,定期进行误差校正来提高系统的稳定性和精度,减少误差;实验结果表明,该平台的系统完全可以使模拟光源按照预计的轨迹运动,所设计的程序具有可靠性。
In order to solve how to more efficient use of solar energy,by observing the position of the sun in the sky and the sun trajectory scientific analysis,a comprehensive forecast operating position of the sun and reproducible methods is presented through simulation platform.In the system,the sun＇ s elevation angle and azimuth are calculated by SCM based on the input date,and converted it to the number of motor drive pulses to achieve the motor driven actuator frequency conversion at different times at different rates movement so that the analog source to reach a predetermined position;at the same time the actual motor encoder pulse are measured on a regular basis in order for the system to correct and improve the stability and accuracy of the system,reducing errors.Experimental results show that the system can make the platform for analog light source in accordance with the expected trajectory,the program is designed with reliability.
