With the increase of private cars, urban roads become more and more crowded, the role of traffic lights is
3、more important. So the reasonable control of the design of a traffic light system is of great significance. This paper describes a SCM based traffic light control system. The system uses 8051 as the control center, seven-segment LED digital display as a waiting or travel time and LED traffic light a
4、s red, yellow, green display. System is automatically reset on power, using the countdown time method to display and four groups of red, yellow, and green light emitting diodes used as a simulation of traffic lights. It can simulate all kinds of road traffic lights control the situation. Key words: LED digital display;SCM;Traffic 第 2 页 目录 第一章 绪论 . 1 1.1 引言 1 1.2 选题背景与意义 2 1.3 研究现状 3 1.4 论文主要研究内容. 5 1.5 主要章
