在FPGA中实现交通灯控制系统的设计

Traffic lights control system design in FPGA

伴随着中国经济的快速发展,城市规模越来越大,机动车辆越来越多,给城市交通带来了巨大压力。而传统交通灯控制系统是通过采用中小规模集成电路,或者是采用单片机和PLC等控制芯片进行设计,从而存在控制精度低、电路设计复杂、系统维护困难、成本居高不下等问题。本文采用FPGA的cyclone II芯片,用Verilog HDL硬件描述语言,通过Quartus II软件进行综合仿真,对各功能模块进行设计,然后通过连线组合各底层模块来实现顶层模块设计。

With the rapid development of China＇s economy,the increasing scale of the city,motor vehicles,more and more trafifc to the city brought tremendous pressure.Aimed at the traditional problems such as inaccurate control,complex peripheral circuits,inlfexible program modiifcation and higher costs,the design trafifc light control systems adopt single chip microcomputer as a control chip,the system of each functional module is designed FPGA with Verilog hardware description language and Quartus II software platform.Each functional module component symbols is added,and then achieve top-level module design through the connection combination from each bottom-level module.
