十字路口交通灯控制器的设计

ABSTRACTIn recent years,with the rapid development of science and technology,the application ofsingle-chip microcomputer are to depth.In real-time detection and automatic control systemof single-chip applications,Single-chip is often used as a core component,only single-chipknowledge is not enough,It should also be based on the specific hardware structure andapplication of object-specific features of the software to be perfect.This paper describes amicrocontroller-based intelligent traffic light control system design and simulation.System ata crossroads two-lane traffic flow in accordance with the situation in control of the trafficlight changes according to the laws of a particular.The first study,such as Intelligent Transportation Research significance and analysis,point out thatthe status quo of the shortcomings of the existence of traffic lights and made things better.Intelligent trafficlight control system is usually in order to achieve automatic control and in emergency situations tomanually switch the signal to allow priority access to special vehicles.The article also AT89S52 MCU pinstructure and important functional characteristics are introduced,at the same time intelligent traffic lightcontrol system carried out a detailed analysis.Finally,simulation and embedded system protuesdevelopment platform to use,the use of software protues traffic lights control system simulation.KEY WORDS:AT89S52 single-chip microcomputer;Intelligent traffic light controlsystem;PROTEUS simulation
