51单片机下罗路口交通灯控制实验

The control experiment of traffic lights at the lower intersection of 51 single chipmicrocomputerComputer Department Computer science and Technology Major122682013#####Instruct0r#[Abstract]The development of microcomputer technology is computer technologybased on computer,rounding the huge body,only by the main control chip to control thecircuit,now the application of SCM technology is very extensive,especially in today'sindustry 4 times,new electromechanical integration more cannot do without electricalcontrol.In recent years,the development of traffic light control system has also beendeveloping with each passing day.The traffic lights have become the marking tools for thetraffic order of the vehicles in the city.This design is based on the development of AT89C51microcontroller traffic lights control system,the purpose is to achieve the control of trafficlights in all directions through the 51 MCU to facilitate people's lives.The design is based onthe 51 Series MCU AT89C51 as the core processor,connecting with the core traffic processorand its own module,display module,driving module,traffic flow monitoring module andkey press.The software includes the development platform,the main program,the displaysubroutine part and the key part.The design of traffic lights is realized through the controlof the monolithic computer.It is verified that the design of the traffic light system can meet the requirements of thisdesign,easy operation,reliable operation,and meet the design standards.And the design ofthe traffic light system is low cost,high cost performance,practical.[Key words]AT89C51;traffic light;Digital tube;timing1
