摘要
介绍了基于FPGA设计思想研究单交叉口交通灯控制的一种方案,以传统的韦伯斯特理论为基础,分析单交叉口交通信号的周期时长和绿信比,对交叉口的周期时长和有效绿灯时间进行配时,用VHDL语言编写程序,对个部分模块进行设计,在QUARTUSⅡ平台上进行仿真和并下载到可编程器件上进行验证,结果表明该系统的设计方案正确。
The article introduces a design scheme of FPGA-based traffic light control on the single intersec tion. According to the traditional theory of Webster, analyze the cycle of single intersection traffic signal length and split ,calculate the cycle time and the effective green time. The VHDL hardware language is a- dopted to design program, compile and simulate under Quartus Ⅱ. Then generate topfiles and download them to FPGA chip for verification. The simulating results show that the design method is correct.
