Abstract

In this paper, an energy-saving control system for intelligent street lamps based on STM32F103C8T6 microcontroller is designed, and dynamic lighting control is realized by integrating D80NK infrared sensor, LD2451 radar sensor and KDT331 photoresistor. According to the requirements of the "Urban Road Lighting Design Standard" (CJJ45-2015), the system adopts three operation modes: maintaining the lowest illumination (5lx) when there is no car, "lighting with the vehicle" when the traffic flow is sparse, and full power lighting when the traffic flow is dense. The hardware design includes a multi-protocol communication interface (I2C/SPI), a parameter adjustable module (8 buttons + OLED display) and a dual-stage regulated power supply (LM7805+AMS1117), which supports real-time traffic perception and adaptive dimming. Measurements show that the system can reduce energy consumption by about 58% (0.44 kWh per lamp per day), while extending the life of the equipment and reducing light pollution. Its low-cost and easy-to-deploy characteristics are suitable for the promotion of urban arterial roads, helping smart cities and achieve the "double carbon" goal.
