摘 要
本次设计是实现基于CPLD下的交通信号灯的控制电路,它将有效地解决在人流量和车流量的时间分配问题,提供高效地有条不紊的服务,通过交通灯的显示和智能化控制功能,可以让人们井然有序的参与到交通活动中来。在夜间车流量相对较少的情况下,采用黄灯闪烁预警,是行车减速慢行即可,让其尽快通过,因为不必要的等待会造成时间上的浪费。
Verilog作为一种硬件描述语言,被广泛的应用于电路设计中,可通过不同的器件来实现。利用Verilog语言编程的设计方法设计交通灯控制系统,用其来实现道路交通有条不紊地运行,突出了Verilog语言的良好的可读性、可移植性和易理解等优势,并通过Quartus II完成综合和仿真演示。此程序通过下载到CPLD芯片后,便可用户与实际的交通系统控制。

Traffic lights under CPLD based designs
ABSTRACT
This design is to realize the traffic lights control circuit based on CPLD under, it will effectively solve the traffic and time distribution of traffic problems, and to provide the services efficiently in an orderly way, through traffic lights display and function of intelligent control, can let the people involved in the transportation activities orderly. Under the condition of relatively few cars at night, use yellow lights flashing warning, is driving slow down, let it pass, as soon as possible because unnecessary waiting will cause the waste of time.
Verilog as a kind of hardware description language, as a kind of widely used in the circuit design, can be done by different devices. Use Verilog language programming design method of design of traffic light control system, and use it to realize the road traffic run methodically, highlighted the Verilog language good readability, portability and easy to understand, such as advantage, and through the Quartus II complete comprehensive demonstration and simulation. After this program download to CPLD chip, can the user and the actual traffic control system.
Keywords:The traffic light ; CPLD ;Verilog language ;The night ;Quartus II
