| 摘 要： | 为了适应高等院校课程改革的要求，CPLD技术课程在教学方法上发生了很大变化，采用一套交通信号灯控制方案，该方案采用“项目为载体、任务为驱动”的方式运用于教学，突出项目开发的流程和模块化设计的思想。通过编辑、编译和器件编程，将编程器文件以在线配置方式下载到CPLDA实验板的EPM1270T144C5N器件中，经实际电路测试验证，能实现主、支干道信号的互锁和自锁，准确实时显示主、支干道各种灯的剩余时间，达到了预期的设计要求。

| Abstract: | To meet with the requirements of the curriculum reform of the institutions of higher learning, great changes have occurred in teaching methods of the CPLD technology courses by adopting a set of traffic lights control program, The program uses ＂project- cartier, task-driven＂ approach which highlights the project development process and idea of modular design. By editing, compiling, and device programming, the programmer file is downloaded to CPLD experimental board EPM1270T144C5N devices by online configuration. The system has achieved the desired design requirements by test verification with the actual circuit. The circuit can not only achieve the main and branch roads signal interlocking and serf-locking, but also can accurately display remaining time of he real-time of main and branch roads lights. |
