摘　　要：为充分利用新能源并解决景区照明能耗高、观赏性低、光源固定等问题,设计一种基于STM32F103C8T6光电跟踪的多功能太阳能光伏花。采用光电跟踪法收集尽可能多的太阳能并将其转换为电能储存在锂蓄电池中,以为装饰灯和其他模块供电。同时,设计了L298N电机驱动模块,控制受光模块与小车以反方向转向运动,解决由小车方向导致太阳能电池板同向运动的问题。用户可通过蓝牙控制光伏花的开花、闭花和移动。在相同环境下分别测试了视日轨迹跟踪和光电跟踪对太阳能的吸收效率,结果表明光电跟踪法在成本控制和对太阳能的吸收效率上表现更优。利用光电跟踪法可充分利用太阳能,不易受突发天气影响。To fully utilize new energy and solve the problems of high lighting energy consumption,low ornamental value,and fixed light source in scenic areas'lighting,a multifunctional solar photovoltaic flower based on STM32F103C8T6 photoelectric tracking is designed.It uses photoelectric tracking method to collect as much solar energy as possible and convert it into electrical energy for storage in lithium batteries to power decorative lights and other modules.At the same time,an L298N motor drive module is designed to control the light receiving module and the car to move in the opposite direction,solving the problem of the solar panel moving in the same direction caused by the car's direction.Users can control the flowering,closing,and movement of photovoltaic flowers through Bluetooth.The absorption efficiency of solar energy by visual trajectory tracking and photoelectric tracking are tested separately in the same environment,and the results indicate that the photoelectric tracking method performs better in cost control and absorption efficiency of solar energy.The use of photoelectric tracking method can fully utilize solar energy and is not easily affected by sudden weather events.
