摘　　要：十字路口上的交通灯有效地解决了现代社会中人们出行时容易碰到的拥堵问题,从而为人类的生活提供了便利。基于此,从十字路口交通灯的问世历程出发,基于型号为AT89C51的单片机,设计出了能满足交通路口4个方向直行要求的硬件电路,同时依据硬件电路和控制器AT89C51单片机的工作原理,编写了符合实际通行需求的程序,通过proteus仿真软件证实了所做的硬件和软件设计能够实现十字路口交通控制的要求,最后提出了希望交通灯能够更智能化的期望。The traffic lights at intersections effectively solve the congestion problem that people often encounter when traveling in modern society,thus providing convenience for human life.Starting from the history of the emergence of traffic lights at intersections,this article designs a hardware circuit based on the AT89C51 microcontroller that can meet the requirements of straight traffic in four directions at intersections.At the same time,based on the working principle of the hardware circuit and controller AT89C51 microcontroller,a program that meets the actual traffic requirements is written.Through Proteus simulation software,it is confirmed that the hardware and software design can meet the requirements of intersection traffic control.Finally,the expectation is put forward to make traffic lights more intelligent.
