基于FPGA的多功能交通信号控制器设计

The Design of the Multi-functional Traffic Signal Controller Based on FPGA

本文介绍了基于FPGA的多功能交通信号控制器的设计,该控制器不仅有指示灯信号以及每个指示灯的倒计时的秒数显示,还完成了每方向绿灯最后几秒信号灯闪动及智能化设计思想。该课题较多地综合数字逻辑电路知识,把它作为可编程器件开发的教学实验课题有实用性和趣味性,进一步提高了数字逻辑电路和可编程器件应用的实验教学水平。

The design of multi-functional traffic signal controller based on FPGA is presented in this paper. The controller has built-in pilot lamp signal and the lamp can display the count-clown time in second. It is also intelligently designed to flash the pilot lamp in the last few seconds of the green light in each direction. There is plenty of comprehensive digital logic circuit knowledge involved in the project. It can be used as a teaching material to develop a programmable logic device due to its practical and interest nature. It will bring the teaching and experiment of digit logic circuit and programmable logic device to a new level.
