摘 要: | 通行时间固定,人为调整通行时间导致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。这里根据路口车辆的排队长度调整通行时间,以STC90C52RC单片机为控制核心,用光电传感器检测排队长度。以光电传感器的返回值为依据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。 |
关 键 词: | 自动控制技术及其他学科;模拟交通灯;单片机;控制算法;车辆检测 |

Abstract: | The problem of the passing time limited and unreasonable passing time caused by the manual adjustment makes the traffic lights to play a role only when the number of cars is beyond a certain range. When the traffic flow is heavy, the traffic lights can not make corresponding adjustments; when the traffic flow is small, it wastes time. This paper makes the passing time which can be adjusted according to the queuing length of cars in the crossroads. We select STC90C52RC as the core chip, detect the queuing length by photoelectric sensor. The returned value from photoelectric sensor can be used to judge whether increase the green light time in the next cycle, thereby change the remained time of cars in the crossroad, thus achieve the optimized control of the traffic lights to the road conditions. |
Key words: | automatic control technology and other subjects; the simulating traffic lights; singlechip; control algorithm; detection of cars |
