基于温湿度传感器的交通灯配时控制系统设计

Traffic light timing control system design based on temperature and humidity sensor

当前我国绝大多数城市交通信号灯仍采用定时分配的控制方式,并不能满足城市发展中交通流量不断变化的状况。目前一些改进的交通灯控制方式也只是简单地将交通周期分为高峰期与一般时期,不具备实时跟踪性能。提出了一种温湿度感应的交通灯配时方案。该方案以AT89C51单片机为核心,采用温湿度传感器对当前温湿度进行采集,利用DS1320时钟芯片提供时间日历,对当前的气候、天气及时段进行判断,从而对交通灯配时进行合理配置,设定情景相对应的工作模式。系统设计通过Protues软件仿真验。

In our country, most of the urban traffic signal fixed cycle control method that light, which control manner cannot meet and adapt to changes in short-term tluctuation of traffic flow. A traffic light timing scheme of temperature and humidity sensor is proposed. The scheme takes the single chip processor AT89C51 as the core,. Acquisition of the temperature and humidity sensor is adopted to the current temperature and humidityy. DS1320 calendar clock chip provides time and calendars. Thus, climate, weather, and duration are judged to configure traffic light timing,set the scene the corresponding work mode. System design is verified through Protues software simulation.
