摘要
通过分析交通复杂十字路口信号灯的控制要求,结合S7-200的控制性能,在传统的交通灯控制基础上增加了左转控制功能,对系统进行了软、硬件设计,实现了复杂十字路口的东西南北方向的直行、左转及人行道信号灯的合理控制的功能,实验验证了方法的可靠性。
Analyzing the traffic control requirements of complicated crossroads,knowing S7-200's feature,carry out the software and hardware design,and add the controlling function of turning left to the traditional method. It has proved that this system can complete the practical traffic control of complicated crossroads,including controlling cars’ moving straight,turning left and the operation of the sidewalk.
