【摘要】:针对当前道路车辆逐渐增多,固定配时方案的交通信号系统无法满足复杂车流变化的情况。提出将感应控制方式融入到交通信号系统中,并与定时配置方案相结合,采用FPGA技术设计一种自适应的交通控制系统。通过Verilog语言编写各模块的控制程序,在QuartusⅡ软件环境下进行综合编译与仿真验证,设计出能够采集路口车流信息并实时反馈、自动调整配时方案的交通信号控制系统。然后,结合开发板模块电路,选择合适的电子器件,设计车流检测和交通信号模拟显示电路,并通过管脚约束的方式,完成外接模拟显示电路与开发板的硬件连接,下载程序并调试运行。最终,在实验室完成自适应交通信号系统的硬件电路调试。
[Abstract]:In view of the increasing number of road vehicles and the fact that the traffic signal system with fixed timing scheme can not meet the complex traffic flow changes, the inductive control mode is integrated into the traffic signal system and combined with the timing configuration scheme. An adaptive traffic control system is designed by using FPGA technology. The control program of each module is compiled by Verilog language, compiled and simulated under the environment of Quartus 鈪,
