ABSTRACT
This paper mainly introduces the design principle, hardware circuit design and program design of the intelligent traffic signal light system. Through monitoring and controlling the state of traffic lights, it can realize orderly road traffic, reduce the risk of traffic congestion and accidents, and improve the operation efficiency of urban traffic. The design scheme of this paper is simple and practical, stable and reliable, easy maintenance, and can provide strong technical support and reference for the urban traffic management department.
This paper designs an intelligent traffic signal light system based on STC89C51 SCM, including the minimum system, 74HC245 circuit, key button and digital tube display. The system displays the state of the traffic signal light through the two-bit common cathode digital tube, and can set the timing through the key, and also has the function of buzzer prompt. The system can realize intelligent traffic signal control and improve the safety and efficiency of road traffic.
Key words: intelligent traffic light; single microcontroller; display; timing; buzzer
