基于单片机的智能交通灯系统设计

Design of Intelligent Traffic Lights System Based on Single Chip Microcomputer

为了实现交通道路的先进和科学化管理，该文提出了一种基于单片机的智能交通灯控制系统的设计与仿真。该系统能够根据十字路口两个方向的车流量来自动地控制交通信号灯按规定的规则开闭，系统通常以自动方式工作，并也能在紧急情况下以手动方式切换信号灯让特殊车辆优先通行。采用了＂Proteus＋Wave6000＂的仿真方法，仿真结果表明，该系统功能正确，运行状况良好。

With the purpose of realizing the advanced and scientific management for traffic roads, the article proposes a kind of design and its simulation of intelligent traffic lights control systems based on the Single Chip Microcomputer（SCM）. According to the traffic flows from the two directions at the intersection, the system is able to automatically control the opening and closing of the traf- fic lights in accordance with the prescribed rules, the system usually is working in the automatic mode and also can make switchovers for the traffic lights to allow the special vehicle going first by manual operation mode in case of emergency. The simulation method of ＂Proteus ＋ Wave6000＂ is adopted; the simulation results show that the system is of correct functions and good operating conditions.
