基于单片机的交通灯系统设计仿真

随着私家车的不断增加,传统的交通控制系统已经不能满足路口交通的需要,因此,交通控制系统正朝着智能化、低成本化方向不断发展。文章完成了以STC89C51单片机为控制核心的十字路口交通控制系统,该系统相比于传统交通系统,除了包括车辆信号灯指示模块、人行道通行指示灯模块、计时模块以外,还包括了紧急按键模块、通行时间加减模块、红外遥控模块、行人闯红灯报警模块。除了能简洁、直观地显示十字路口的通行规则,提高车辆和行人的通行效率外,系统还具有一定的可扩展性,将进一步提高十字路口的交通安全和通行效率。

Design and simulation of traffic light system based on microcontroller

With the continuous increase of private cars, the traditional traffic control system can no longer meet the needs of intersection traffic, so the traffic control system is continuously developing towards intelligence and low cost. The article completed the intersection traffic control system with STC89 C51 single-chip microcomputer as the control core. Compared with the traditional traffic system, this system includes a vehicle signal indicator module, a sidewalk traffic indicator module, and a timing module. In addition to the emergency button module, traffic time addition and subtraction module, infrared remote control module, pedestrian red light alarm module. In addition to concisely and intuitively displaying the traffic rules at intersections, the efficiency of vehicles and pedestrians can be improved. The system also has certain scalability, which will further improve traffic safety and efficiency at intersections.
