基于FPGA的路灯控制系统

Design of Road Lantern Control System Based on FPGA

FPGA兼容了PLD和通用门阵列的优点,可实现较大规模的电路,编程也很灵活。本设计是要基于FPGA实现一个模拟路灯控制系统,整个路灯控制系统设计分为数字电路部分和模拟电路部分。通过对所设计的程序进行编译和仿真,在FPGA上下载验证,系统能够完成按时开关灯,同时可根据路上光线明亮程度和移动物体状况控制路灯开关的功能。当路灯出现故障时,系统还会发出故障报警并显示故障路灯的编号。

FPGA takes the advantages of both PLD and general gate arrays, it can realize large-scale circuit and its programming is very flexible. In this paper, a simulated road lantern control system is designed based on FPGA, including two parts, which is digital circuit part and analog circuit part. The designed program has passed compiling, executing, and verifying on FPGA. The results show that the system can turn on or off the lamps on time according to the illumination conditions and the statuses of moving object, and can also produce fault alarm and show the fault information when there is something wrong with the road lantern.
