设计了一种基于AT89S52单片机芯片的交通信号灯控制系统.该系统除具有交通灯控制功能外,增加了现场实时控制及交通信号灯故障检测功能,提高了交通灯的智能化、可靠性和实用性,可有效提高交叉口的通行能力.

The thesis design traffic light control system based on AT89S52 MCU.In addition to fundamental functions of traffic lights,it also has functions of emergency case processing and signal fault detection.The system also uses infrared remote real-time control technology and PC to achieve the real-time control.Using MCU for traffic lights control can improve the intelligence reliability and practicality of traffic light.So it can improve the traffic capacity at crossings.
