Design of Intelligent Traffic Light System Based on 51 Single-chip Microcomputer
This article presents the design of intelligent traffic streetlights,introducing an intelligent lighting system for urban road automatic control systems.The lighting control system is designed with an STC89C52 microcontroller as its core.The switching of traffic light timing is achieved through the use of lighting brightness control and key-controlled clock selection.Timer devices T0 and T1 are employed to manage and control the on and offtimes within the system.A photosensitive resistor automatic management system is applied to regulate the brightness of the traffic road lighting.The control method and delay time of the streetlights are displayed on an LCD screen.This system offers advantages such as low cost and smooth operation.This controller is suitable not only for sidewalks on both sides of the road but also for residential corridors.
