Intelligent Solar Chasing Street Light System Design and Fabrication Summaries

Abstract

This project adopts an advanced microcontroller as the core control unit, which accurately commands the servo drive, realizes the real-time light chasing and charging function of the solar panel, and effectively manages the power supply system of the street light. At the same time, the system is able to continuously monitor the operation status of the servo within the range of 0 ° to 180 ° to ensure that it is trouble-free and not offline. The hardware system construction consists of five modules: a power module, solar panel module, servo module, street light module, and Organic Light-Emitting Diode (OLED) display module. Each module works together to support the stable operation of the whole system. The system workflow is to accurately determine the direction of the light source by collecting real-time light intensity data through four precision photoresistors. Subsequently, the microcontroller intelligently controls the helm module based on these data to drive the solar panel to rotate within a range of 180 ° to accurately track the sun’s orientation. The street light provides two lighting modes, automatic and manual, to meet the needs of different scenarios. During the daytime, the solar panels work actively to monitor and collect solar energy efficiently in real-time, meanwhile, when night falls, the solar panels switch to standby mode and the streetlights light up automatically, illuminating the road ahead for pedestrians. Compared with the traditional solar street lights on the market, the intelligent solar light chasing road system introduced in this project has significant advantages. Its unique light-chasing algorithm enables the solar panel to continuously track the light source from sunrise to sunset, thus significantly improving the charging efficiency. Compared with traditional street lights, the biggest advantage of this project is the proposed light-chasing algorithm, which can always charge from sunrise until sunset, making the charging efficiency increase by 38% to 47%. The charging efficiency is 20% to 38% higher than that of traditional street lamps. Simultaneously, the biggest advantage of this project is that the power storage capacity is higher than 35% of the traditional solar street light. Bringing users a more durable and stable lighting experience.
