城市智能交通灯系统毕业论文

毕 业 论 文（设 计）题目： 智能交通灯控制系统（ Title ） ： Intelligent traffic light control system 智能交通灯控制系统摘要本设计就是以单片机为架构的智能交通灯系统。本系统由单片机系统、LED 显示、交通灯演示系统组成。系统包括直行、左转、右转、以与基本的交通灯的功能。系统除基本交通灯功能外，还具有倒计时、时间设置、紧急情况处理、分时段调整信号灯的点亮时间以与根据具体情况手动控制等功能。目前的交通灯闪耀周期固定，导致上下班高峰期主干道路等待时间长。本设计增加高峰期模式，进入高峰期时间段，通过调节闪耀时间缓解车流量大的道路压力。同时还增加了交通灯系统的人行道盲人提示功能、急车紧急通过功能，可有效防止上下班时交通堵塞和车辆、人员滞留。比起普通交通灯控制系统，此系统提高了交通灯控制的效率，保证交通有序进行。关键词：AT89S52；交通灯； LED 显示Intelligen traffic light control system AbstractThis design is based on SCM for intelligent traffic light system architecture. This system consists of SCM system, LED display, traffic lights demonstration system. The system comprises a straight line, turn left, turn right, and the basic traffic lights function. In addition to the basic traffic lights function, also has the light time countdown, time setting, emergency handling, sub-period adjustment of signal and manual control functions according to the specific circumstances.At present, the traffic lights fixed period, resulting in the rush hour of trunk road to wait for a long time. Increase the peak pattern design, enter the peak period of time, by regulating the flashing time relieve the pressure large flow of car. At the same time also increased the traffic light system sidewalk blind prompt function, acute emergency vehicles through the function, can effectively prevent the commuting traffic and vehicles, staff retention. Compared with ordinary traffic light control system, the system improves the efficiency...
