太阳能智慧路灯设计

针对目前太阳能路灯存在的发电效率低,控制性差,能耗高的问题,设计了一种新型太阳能智慧路灯。采用STM32芯片作为主控制器,利用BH1750光照传感器模块采集光照数据,通过光照差值驱动电机带动光伏电池板进行太阳跟踪,提高发电效率,同时利用采集到的光照数据实现对天气的阴晴判断,避免了不必要的电机启停损耗。电机选取超低转速的直流减速电机,在提高转动精确性的同时,简化了机械设计。照明控制方式也在传统时控和光控基础上增加了微波感应控制,通过智能调光进一步达到节能目的。

Ainfing at the problems of low efficiency, poor controllability- and high energy- consumption of solar street lamps at present, a new type of solar intelligent street lamps is designed. The STM32 chip is used as the main controller and the BH1750 light sensor module is used to collect the illunfination data. The photovoltaie panel is driven by the illunfination difference motor to track the solar energy and the efficiency of power generation is improved. At the same time, the light data collected can be used to judge the weather and avoid unnecessary- starting and stopping loss of the motor. Motor selection of ultra-low speed DC deceleration motor, in order to improve the accuracy of rotation at the same time, simplify the mechanical design. Based on the traditional time control and light control, microwave induction control is added to the lighting control mode, which can further achieve the purpose of energy saving through intelligent dimming.
