基于FPGA的模拟路灯控制系统的设计

The Design of Street Light Simulation Control System Based on FPGA

以FPGA芯片为控制核心,设计了一个模拟路灯控制系统,该系统可以实现自动设定显示开关灯时间、根据环境明暗和交通状况自动开关灯等功能。外围硬件电路主要包括光线信号和位置信号的采集、按键输入、路灯指示和故障检测以及声光报警和显示电路。FPGA核心控制电路部分主要包括模式调节模块、正常时间计时及调试模块、路灯同步定时和分别定时开关灯模块、光线控制模块、交通状况控制模块和译码显示模块。每个模块都通过了编译调试且仿真测试结果正确,实现了模拟路灯控制系统的控制功能,达到了设计要求。

By using FPGA as the core,the paper introduces the design of street light simulation control system to realize functions of automatic adjusting and showing the time of turning on or off,and automatic turning on or off according to the light intensity and traffic condition.The peripheral hardware circuits mainly include the parts which collect the signal of shining and position,button input,street show,fault detection,sound,light alarm and display.The core control circuits based on FPGA mainly include mode adjusting module,normal timing and adjusting module,the modules which control the light being turned on or off synchronously and independently,the modules controlled by shine signal and traffic condition,and the decode display module.Every module has passed the compiling and adjusting process with right simulation results.The system realizes the whole control function of the street light simulation system and meets the requirements of the design.
