摘要
针对传统MCS-51单片机设计交通信号机存在的不足,在进行设计需求分析和功能分析的基础上,选用ATMEL公司的ATmega128单片机进行新型智能交通信号机的设计,并给出了各功能模块电路的原理图和主程序流程图,测试结果表明研制的交通信号机性能稳定,功能强,便于实现“绿波带”控制和交通网络协调控制。
There are many shortages of traffic controller design based on traditional MCS-51 single-chip microcomputer.On the foundation of design need analysis and function analysis,this paper chooses the ATmega128 single-chip microcomputer of ATMEL corporation to implement the develop of new-kind intelligent traffic signal controller,and provides the electric circuit diagram of each function configuration and flow chart of main program.The practical application indicates that the new-kind intelligent traffic singal controller posseses reliable performance and powerful functions,and is convenient to achieve the "Green Wave Band" control and traffic network coordinated control.
