摘要:在本次的毕业设计中,主要是以80C51单片机为核心的交通灯信号控制器。系统中实现控制各方向灯和转向灯的状态转换和转换顺序,键盘控制设置了红、绿、黄灯亮延迟时间和改变了当前红绿黄指示灯和方向转向灯的状态,通过显示器来显示状态转换剩余时间这些功能。首先时间延迟由单片机内部时钟编程产生,其次人机接口包括键盘、十字路口红绿黄指示灯和方向转向灯、显示器等,最后通过完整硬件电路图和软件代码完成仿真。通过模拟仿真实现交通灯的运行,可以把复杂的交通状况进行实时调整,解决交通运行过程中的堵塞。47258

Agent Controlled Traffic Lights
Abstract: The design is based on 80C51 microcontroller as the core to design the traffic light controller. System to achieve control of each lamp and turn signal state transitions and the conversion sequence, keyboard control set of red, green and yellow light time delay and change the current direction of the red, green and yellow lights and turn signals the state through the display to display status these remaining time conversion functions. First, the time delay is generated by the microcontroller internal clock programming, followed by human interface includes a keyboard, red, green and yellow lights crossroads and direction of turn lights, monitors, and finally completed the simulation through the complete hardware schematics and software code. Realized by simulation run traffic lights, can be complicated traffic situation in real time to adjust, the process of resolving the traffic running clogged.
