单片机的交通灯控制系统的设计VIP专享VIP免费

I摘要新中国成立以来，中国经济蓬勃发展，道路大桥一条条修建起来，汽车数量也越来越多，道路交通拥堵问题成为当今社会共同关心的热点话题。交通灯显得尤为重要，现有的交通灯存在一些缺点当十字路口的交通灯时间是固定的，不能改变。车流量较大时，不能根据车流量调节红绿灯的通行时间。遇到紧急情况，比如消防车、救护车和警车在执行公务时不能及时通过，耽误时间。 本次交通灯设计以单片机 AT89C51 为核心，根据单片机知识和当前交通灯的发展，设计一款交通灯有基本的功能，还能够根据车流量调节红绿灯时间，设置手动按键，在遇到紧急情况时能够让救护车、警车和消防车通行。改善交通拥堵的情况，为人民创造出愉快的出行体验。交通灯具有简单、实用性强、灵活度好、操作方便等特点被广泛应用。缓解了交通拥堵问题。关键词: 交通灯，车流量，紧急控制。IIAbstractSince the founding of New China, China's economy has boomed, road bridges have been built one by one, and the number of cars has also increased. Road traffic congestion has become a hot topic of common concern in today's society. The traffic lights are particularly important. The existing traffic lights have some disadvantages. When the time of the traffic lights at the intersection is fixed, it cannot be changed. When the traffic volume is large, the traffic time of the traffic lights cannot be adjusted according to the traffic volume. In emergency situations, such as fire trucks, ambulances, and police cars failing to pass in time when performing official duties, delaying time.The traffic light design is based on a single-chip microcomputer AT89C51. Based on the knowledge of the single-chip microcomputer and the current development of traffic lights, a traffic light is designed to have basic functions. Allows ambulances, police cars and fire trucks to pass. Improve traffic congestion and create a pleasant travel experience for the people.Traffic lights are widely used because they are simp...
