Modeling and Simulation of Intelligent Traffic Controller Based on FPGA

介绍了一种采用FPGA设计方法进行建模与仿真的智能交通控制器。采用模块化的设计方法,首先,为了满足智能交通控制器的功能需求,分析了各个子模块的建模设计思想,仿真验证子模块的设计正确性,再将各子模块整合成顶层智能交通控制器,通过Modelsim软件仿真测试验证智能交通控制器的控制正确性。该智能交通控制器使用EP3C10E144C8芯片实现。测试表明,该智能交通控制器能实现交通灯信号灯的控制和剩余时间的倒计时显示。

A intelligent traffic controller based on FPGA technology to model and simulate was presented. Using the modularization programming method, sub-modules of intelligent traffic controller was analyzed firstly to meet the functional requirements. The simulating result shows that the function of sub-module was correct. Secondly, all sub-modules was integrated in the top intelligent traffic controller.Using the Model Sim software, the operation correctness was proved by simulating result. This driver was realized by EP3C10E144C8. The testing result shows that the functional requirements was realized by the intelligent traffic controller, including the control of traffic lights and thc display of countdown to the remaining time.
