"基于单片机的交通信号灯控制器设计与实现"

The document titled "Design and Implementation of Microcontroller-based Traffic Light Controller" explores the application of microcontrollers in real-time detection and automatic control systems, focusing on the role of microcontrollers as core components in these applications. The author emphasizes the need for a combination of knowledge about microcontrollers and specific hardware structures to create effective systems. The document discusses the importance of traffic signal control systems in maintaining order and safety at intersections, where vehicles move, pedestrians cross, and lanes and walkways intersect. It highlights the use of 74190 chips for countdown control, with two connected chips for each direction. Additionally, the system uses 74153 chips to preset the initial values for the countdown, based on the analysis of the time settings. The author also mentions the ability to detect and display the flow of vehicles using dual digital tubes. The system is praised for its practicality, simplicity of operation, and strong expandability. In summary, the document provides valuable insights into the design and implementation of a microcontroller-based traffic light controller, offering a practical and efficient solution for managing traffic flow at intersections. The author's emphasis on the need for a combination of microcontroller knowledge and hardware-specific understanding is indicative of the comprehensive approach required for successful system design and implementation. This document serves as a valuable resource for engineers, developers, and researchers in the field of traffic control systems.
