基于单片机的模拟交通灯系统优化的设计
Optimized Design of Traffic Lights Simluting System Based on Singlechip
通行时间固定，人为调整通行时间及所调时间不合理等问题使得交通灯只能在车流量达到一定范围才能发挥作用，当车流过多时，无法做出相应的调整；当车流少时，会造成时间浪费。本文使通行时间可根据路口车辆的排队长度进行调整，以STC90C52RC为控制核心，用光电传感器检测排队长度。光电传感器的返回值确定是否改变下一周期绿灯时间，从而减少车辆在路口的停留时间，以此实现对路面状况的优化控制。
he problem of the passage of time limited,the time adjudted by people and it unreasonable makes the traffic lights play a role,when the number of cars beyongs a certain range.When the traffic flow is heavy ,the traffic lights can not make some adjustments;When the traffic flow is small,it wastes time.This paper makes the passage of time can be adjusted according to the queuing length of cars in the crossroads,selects STC90C52RC as the core chip,detects the queuing length by photoelectric sensor.The returned value from photoelectric sensor judges whe- ther to increase the green light time in the next cycle,in order to change the remained time of cars in the crossroad, acheiving the optimized control of the traffic lighes to the road conditions.
