基于单片机的智能交通灯设计(软件部分)


摘要:随着现在城市发展步伐的加快,已经有越来越多的人拥有自己的汽车,这就给城市的交通造成了很大的压力,城市要有效率的发展那么必须解决交通问题。由于社会主义建设,有许多从事交通建设的研究设计十字路口的工人,创建和设计了很多新的项目,让我国的交通建设取得了一定的进展。目前的交通灯主要用于控制车辆和行人的通道,维护管理相当方便并有了自动化的发展。大量的信号电路正朝着数字化,低功耗,多样性,协调着人与车之间的关系。十字路口交通繁忙,要实现路人与车辆有秩序的来来往往就得依然交通灯自动指挥系统才能完成这种秩序。本系统采用单片机STC89C52来设计交通灯控制器,能根据实际车流量控制STC89C52芯片的P1口设置红、绿灯点亮时间的功能;红绿灯循环亮起,倒计时剩5秒时黄灯闪烁警示。该系统操作便捷,界面优化,扩展功能强。

Abstract:With the expansion of the scale of socialist construction in the city , the city's traffic improved and perfected , smooth traffic has e an important factor in the development of socialist construction. Now, with the increasing number of cars increases , especially for urban transportation construction crossroads traffic safety is quite critical , serious impact on the urban traffic safety. Because of socialist construction , there are many workers engaged in the construction of transportation crossroads of research design , create and design a lot of new projects, so transportation construction to a higher stage of development. Currently , cross light vehicles and people are used to control a channel , not only to facilitate the maintenance and management , and a strong automation. A large signal circuit is toward digital, low-power, diversity , and promote people, vehicles , coordinating the tripartite relationship , and with the social and economic development , resulting in more and more people urban traffic problems , more value- oriented development concerns . This is effective traffic control the flow of traffic , improve road capacity and reduce the significant effect of traffic accidents . Crossroads shuttle vehicles , pedestrians bustling , dealers driveway , walkway person , methodically . So to achieve this depends on what order it? Rely on automatic traffic light control system.
