摘　　要：文章设计基于太阳能电池板对光照强度的敏感性及其输出电压的变化,以STM32F103芯片为核心,通过STM32F103的ADC处理,实现光照强度的测算,利用继电器进行电路机构的控制,从而实现电路能根据光照在太阳能发电装置为电池和负载供电,以及电池单独对负载供电的两种状态下进行切换。太阳能电池板输出电压根据负载变化的偏差,采用设置双阈值的方法实现了对输出电压的准确控制,有效避免了因负载变化引起的输出电压不稳定从而导致电路状态一直切换的不稳定状态。结果表明,该系统可应用于各种需要基于太阳光照来调节电路结构供电的场景,具有较高的实用性。Based on the sensitivity of solar photovoltaic panels to light intensity and the variation of their output voltage,the STM32F103 chip is used as the core to calculate the light intensity through the ADC processing of STM32F103.Relays are used to control the circuit mechanism,so that the circuit can switch between two states:supplying power to the battery and load in the solar power generation device and supplying power to the load separately by the battery according to the light.The output voltage of solar photovoltaic panels is accurately controlled by setting dual thresholds based on the deviation of load changes,effectively avoiding unstable output voltage caused by load changes and constantly switching circuit states.The results indicate that the system can be applied to various scenarios that require adjusting the power supply of the circuit structure based on sunlight,and has high practicality.
