摘 要
我们这个系统运用的是EDA实验箱来进行设计交通灯控制器，在进行模拟之后，实现了用黄、绿、红灯来指挥路上各种车辆交通的功能。用的是VHDL的语言编程和QUARTUSⅡ 6.0来设计，它是运用了FPGA芯片来进行进一步开发的。我们这一个交通灯控制器设计，跟基于单片机的设计是不一样的，向我们展示了FPGA芯片的牛逼功能和与众不同的特性。我们这一个控制器，不仅仅是东西用起来没有问题，而且在车流量很多的南北路口，而且还可以用数码管等来显示此时的状态下，还剩余多少秒。与此同时，我们这个交通灯，还有另一种不同于平时的特殊紧急状态，当路上突发有危险的事情发生的时候，每一个方向的红绿灯都会显示成红灯，并且所有方向都禁止通行，除非是紧急情况已经解除，否则红灯是不会变成绿灯的。用FPGA来进行开发的交通灯，具有很多优秀的特点，比如它的运算速度比较高，可靠性也挺强的，电路很简单，对设计人员要求也不算特别高，并且体积特别小。Altera公司CycloneII系列里面的的EP2C5T144芯片将作为本次设计的主要核心的最小系统，QuartusII软件将会作为本次开发系统的主要平台；我们的设计思路是从上到下，对我们的交通灯系统进行模块化的设计，还有综合他们的所有功能，最后通过一些容易理解的波形仿真，还有硬件的设计，实现交通灯的所有功能。最后再使用手机APP来控制设计的自主转换。

Abstract
We use this system is the EDA experimental box for the design of traffic light controller, green, red light to commanded the traffic function. The VHDL programming language is used the QUARTUS 6 to design it, it is a direct use of the FPGA chip to develop. Traffic light controller design, the system elaborated with the FPGA chip to achieve the design process of digital circuits, show the sharp features of the FPGA chip and design distinctive features. The design intelligent traffic lights controller not only for things, and traffic is almost FPGA north-south direction of the intersection, and also indicates the current state of digital number tube is the remaining number of seconds. There is a different state of emergency, when there is a special FPGA risk, when will be banned in all directions, the lights are red light, wait until the state of emergency after termination, will re start time and display time. Design of traffic lights system based system on FPGA has high system operation speed, high reliability, real-time flash, low failure rate, simple circuit, small size and characteristics. The design is based on Altera CycloneII series EP2C5T144 chip as but the appropriate core of the system is minimum, it can be easily embedded into the traffic light application system of real life, but also the perfect completion of simple signal minimum processing, mathematical calculation and logic control, data acquisition functions we use; the QuartusII software as the main but platform; is but using the top-down design ideas of the system to conduct a comprehensive and appropriate modular design, and but the two party implementation and validation of the one of digital signal one of function of traffic lights through simple waveform simulation and hardware design. Finally, the use of mobile phone APP to control the design of independent conversion.
