一种基于STM32的智能化交通灯设计研究OA

This study designs an intelligent traffic light control system based on the STM32 controller.The system employs STM32 as the main controller,leverages its high performance and rich peripheral interfaces,combined with the HC-SR04 ultrasonic ranging module,to achieve accurate monitoring and analysis of traffic flow.Based on this,it dynamically allocates traffic light time and extends the green light duration for directions with high traffic volume.Through an external interrupt triggering mechanism,STM32 precisely controls the traffic light driving module and enables real-time dynamic adjustment of the traffic lights.The system integrates an OLED display and a buzzer to enhance visualization and operability,and incorporates manual adjustment functionality.Experimental results show that the system can effectively improve traffic efficiency and safety,exhibiting high performance and a good user experience.
