摘要: 为了提高太阳能的利用率,设计了智能型双轴太阳能热水器.该装置以手动调节实现集热管绕水平轴的转动,利用涡轮蜗杆机构的自锁功能实现集热管绕垂直轴的转动;以89S52单片机为核心,依据模块化设计思想,构建了自动控制跟踪系统;以电机定时转动和系统休眠的控制方法减小系统的电能消耗.基于多学科协同仿真技术,对该装置进行了强度分析,对以太阳能电池板代替太阳能集成管的实验装置的测试结果表明,该设计产生的电能提高了20%.Abstract: To improve the utilization rate of the solar energy,the intelligent two-axis solar heater was designed.The heat collecting tubes with ratating around the horizontal axis was realized by the manual adjustment,and the heat collecting tubes with rotating around the vertical axis was realized by the self-locking function of the worm geat.The automatic tracking system was built using 89S52 single-chip microcomputer as core.The power consumption of the control system was reduced by means of the step-motor time turning and the sleeping strategy of the control system.Based on the multidisciplinary collaborative simulation technology.An experimental trial-device with the solar panels to replace the heat collecting tubes was made.Compared with the fixed solar panels,the produced electric energy of this design could improve about 20%.
