智能交通信号灯的设计

Design of intelligent traffic signal lamp[Abstract]:With more and more people like transportation in modern society,private cars have gradually become an indispensable part of modern People'sDaily life.The structure and function of the existing traditional traffic lightingcontrol system have basically realized the basic demands of the current realityof road traffic.However,with the continuous development and expansion ofcities in China,the supporting density and complexity of population and otherbuildings are getting larger and larger,and the traditional traffic lightingcontrol system is obviously exposed to weaknesses and deficiencies.In thiscase,relying on the principle of traffic engineering and based on it,thetechnology involved in the intelligent traffic light control system is docked andcombined,and the existing shortcomings and problems are discussed.According to the basic composition and principle of single-chip trafficautomatic control system,the hardware composition and program designthought are formulated.This system takes AT89C51 MCU as the control core,designs the hardware circuit,uses the simulation software,analyzes the circuitstructure.Draw the function flow chart of the program,and then write theprogram code,and in the built hardware platform for functional testing,according to the debugging results to further improve the program.[Keywords]:traffic light,Vehicle flow measurement2
