| 摘 要： | 针对定时控制无法应付交通流无规律的交叉路口，设计以CPLD为控制核心的单交叉路口半感应控制器。采用层次化设计思想，使用VHDL语言编写控制部分的主程序，并通过MAXPLUSⅡ软件进行仿真。仿真结果显示，系统可实现单个交叉路口交通信号灯的半感应控制，并且系统的控制参数可通过外部输入调节，增加系统的灵活性。

| Abstract: | For the timing control is unable to cope with erratic traffic flow of intersection, this paper designs a single-crossing semi-sensing controller with core of CPLD.Using hierarchical design means designs the program of controller with VHDL, and simulates with software of MAXPLUS ]I .The results of simulation show that this system can achieve semi-sensing control of a single intersection traffic signal.And system parameters can be changed through external input regulation, increasing flexibility of the system. |
