摘要
针对交通信号灯控制器的设计问题,采用层次化的设计方法,应用VHDL语言编制了可变多相位交通信号灯控制器的程序,并利用MAXPLUSⅡ进行了仿真。仿真结果表明:该系统可分别实现2、3、4相位交通信号灯控制,并且各相位的灯时分配能方便地通过设定输入进行调节,增强了系统的灵活性和适用范围。
To the design problem of traffic light controller, the program of controller with VHDL is given and simulated by MAXPLUS Ⅱ by using hierarchical design means. The simulation results show that the system could realize two-phase, three-phase and four-phase traffic light control, and the light time of each phase could be changed by setting input value, the adaptability of the system can be increased by changing the phase and light time of traffic light. 1 tab, 6 figs, 10 refs.
