内容摘要
本毕业设计主要研究一种基于51单片机的智能交通灯设计。
目的是通过单片机控制LED数码管和红、黄、绿三种LED灯的显示，为司机和行人提供活动参考，模拟十字路口交通灯的控制。
实验方法是首先利用Proteus软件实现交通灯系统的仿真程序运行，利用电子CAD制作PCB图并完成硬件制作，最后烧入程序到单片机中，实现控制功能。
主要成果和特色：能正常模拟控制十字路口交通灯的显示。十字路分主干道和支干道（东西向为主干道、南北向为支路），主、支干道交替通行，主干道每次放行29秒，支干道每次放行26秒；每次绿灯变红之前，黄灯先闪3次（秒）。

Content summaryThe graduation research based on 51 monolithic integrated circuit design of intelligent traffic light.Aim is controlled by single-chip microcomputer LED digital tube red, yellow, green and three LED lights display, provides reference for drivers and pedestrians, simulation of intersection traffic control.Method is to first traffic light system by means of Proteus software emulator running, making electronic CAD PCB and hardware production, and burn-in procedures in the SCM, and control functions.Achievements and features: normal analog controls the display of intersection traffic lights. Cross road-the main road and the main road (East-West trunk road, a North-South direction as branches), the main, alternate road access, main road pass 29 seconds at a time, trunk release 26 seconds each before the green light turns red and yellow light to Flash 3 times (in seconds).

Summary
of the main graduation design based on 51 single-chip design of intelligent traffic lights.
Object is achieved by microprocessor controlled digital LED and red, yellow and green LED lights display, provide a reference for the activities of drivers and pedestrians, the crossroads of the analog control traffic lights.
Experimental method is to first use Proteus software traffic light system simulation program to run, making PCB CAD electronic map and complete hardware production, and finally burned into the program to the microcontroller, control functions.
The main results and characteristics: normal analog control traffic lights at the crossroads of the display. Before each green light turns red; roads and branch roads crossroads points (for the east-west trunk road, from south to north branch), the main, branch roads alternating traffic, trunk release every 29 seconds, 26 seconds to release each branch roads , the yellow light flashes 3 times (seconds).

Content summaryThis graduation project mainly studies a kind of intelligent traffic light design based on 51 single chip microcomputer.The purpose is to control the LED digital tube and red, yellow, green three LED lights display, for drivers and pedestrians to provide active reference, simulation of traffic lights at the crossroads of control.Experiment method is to use Proteus software to realize the traffic light system simulation program running, the use of electronic PCB to produce CAD diagram and complete the hardware production, and finally burning into the program to the microcontroller, to achieve the control function.Main results and features: can simulate the control of traffic lights at the crossroads of the normal display. Cross the main roads and branch roads (east-west main road, north-south road), the main trunk road, alternate access allowed 29 seconds for each trunk, branch trunk release each 26 seconds before; every time the green light turns red, the yellow light flashing 3 times (seconds).
