基于交通灯导向功能的重要性,交通信号越来越要求实行左转与直行相分离的多相位配时方案,同个方向的左转、直行车流分别观看一组交通信号灯.该文介绍了采用51单片机实现具有多相位配时功能的交通信号控制系统的硬件和软件两部分.
Based on the importance of the traffic light guidance function, the traffic signal is increasingly required to implement the multi-phase timing scheme with the left-turn and straight-line phase separation and the left turn and the direct traffic flow in the same direction to watch a group of traffic lights respectively. 51 MCU to achieve a multi-phase traffic signal control system with hardware and software functions of two parts.
