Embodiment

[0017] Such as figure 1 As shown, a high-efficiency solar LED street lamp control system based on STM32 includes solar panels, anti-reverse connection modules, MPPT charging control modules, solar cells, LED driver modules and LED lights, and also includes MCU control modules; The output end of the battery board is electrically connected to the MPPT charging control module through the anti-reverse connection module, and is used as the input voltage of the MPPT charging control module to prevent the input direct current from being input into the MPPT charging control module with reverse polarity, so After the input of the MPPT charging control module is filtered, it enters the full-bridge buck-boost topology, outputs the required output voltage, enters the filter and fuse, and then connects to the solar battery to charge it, and the input voltage of the MPPT charging control module and The output voltages are respectively electrically connected to the MCU control module through...

Abstract

The invention relates to an STM32-based high-efficiency solar LED street lamp control system, which comprises a solar panel, an anti-reverse connection module, an MPPT charging control module, a solar cell, an LED driving module, an LED lamp, and an MCU control module. A charging control chip adopts LT8490, thereby realizing maximum power point tracking (MPPT) on the solar panel automatically; automatic boost and buck are realized according to input output feedback; the MCU adopts the STM32 and brightness adjustment adopts a fuzzy PID control algorithm, thereby realizing functions of data acquisition and storage, selection of multiple communication modes, RTC real-time clock, PIR control and LCD display. Advantages of the LT8490 and the STM32 are combined, the solar street lamp efficiency is improved, and functions of the solar street lamp are expanded.
