This paper designs a traffic light control system based on AT89 S51 single-chip microcomputer. The system consists of a single-chip minimum system, a traffic light display circuit, a countdown display circuit, and emergency and special case processing circuits.Proteus and Keil software are used to build hardware simulation circuit and software design, hardware and software joint debugging, to achieve the basic functions of traffic lights and emergency and special circumstances of traffic handling. The simulation results show that this system has the characteristics of simple circuit design, high performance-to-price ratio, good stability, and strong operability, which provides a reference program for further diversification and intelligentization of traffic light functions, and has certain practical value.
