基于VHDL语言红绿灯的设计与实现
摘要:传统的交通灯控制系统多数由单片机或PLC实现,此次是基于EDA技术设计交通灯系统的一种方案。EDA技术的一个重要特征就是使用硬件描述语言(HDL)来完成系统的设计文件,应用VHDL的数字电路实验降低了数字系统的设计难度,这在电子设计领域已得到设计者的广泛采用。这就是针对交通信号灯控制器的设计问题,提出了基于VHDL语言的交通信号灯系统的硬件实现方法。通过对系统进行结构分析,采用了层次化的设计方法,给出了各个模块的VHDL程序,并且利用Max PlusⅡ对应用程序进行了仿真,并给出了相应的仿真结果。通过电路优化设计,可以使用规模更小的可编程逻辑芯片,从而降低系统成本。交通灯控制系统通常要实现自动控制和手动控制其红绿灯的变化,基于FPGA设计的交通灯控制系统电路简单、可靠性好。本系统可控制2个路口的红、黄、。利用Quartus Ⅱ对设计结果进行仿真,发现系统工作性能良好。据此设计而成的硬件电路,也实现了控制要求。

Title : Based on VHDL Language Design and Implementation of traffic lights
Abstract: Traditional signal control system most from the microcontroller or PLC, this is based on EDA technical design traffic signal system of a programme. EDA A significant feature is the use of hardware Description Language (HDL) plete the system design documents, applications VHDL digital circuits experimental reduce the digital system design difficulty in electronic design has been designers are widely adopted. This is for traffic lights controller design, based on VHDL language of traffic lights system hardware to achieve. Through the system structure, the level of the design of the various modules of VHDL procedures, and to use Max PlusII application for a simulation, and to a corresponding simulation results. The circuit Optimization design, you can use smaller programmable logic chips, thereby reducing system costs. signal control system is generally to realize Automatic control and manual control the traffic lights, based on FPGA design of traffic signal system of control circuit simple and reliability. The system to control a road junctions in the red, yellow, green 3 lamp. As a specific law changes. Using Quartus II in the design results in simulation, find that the system performance. The design of hardware circuits, and realize the control.
