Abstract

In the current situation of energy scarcity, various countries are accelerating the use of solar energy, and the production of solar street lights is widely used in the field of public lighting. However, the traditional solar street light has the problems of low control accuracy, low anti-interference ability and high cost. Therefore, this design is optimized for the above problems, so that the solar street light system meets the requirements of stability, practicability, energy saving and environmental protection, and its use has a wider social value. Its intelligent street lamp control system combines the characteristics of photovoltaic cells and the characteristics of battery charging and discharging. It uses AT89C51 single-chip microcomputer as the core and is mainly composed of six parts: battery, LED lamp, solar panel, display, charging circuit, and discharging circuit [1]. At the same time, in order to increase the service life of the solar street lamp battery, this design uses a combination of software and hardware to avoid the battery from overcharging and overdischarging, and finally displays the current solar panel voltage and battery voltage in real time through LEDs to achieve the use of solar energy. The purpose of lighting. The system is simple in design, energy-saving and environmentally friendly, eliminates energy waste, realizes the effective use of renewable resources, and has continuous application value.
