基于SoPC的智能巡迹小车的设计

摘要

本设计以SoPC套件E-Play-1c12上配置的Cyclone系列FPGA芯片EP1C12Q240C8为控制单元,加以直流电机、光电传感器、超声波传感器和电源电路以及其他电路构成.控制小车在寻轨区能够沿黑线行驶,并能在相应的区域加/减速,进入寻光区后开始在光源的引导下到达终止线停止.同时,在小车行驶过程中车首点阵式液晶滚动显示字幕,实时显示小车行驶的时间及路程.%This design takes the Cyclone series FPGA CMOS chip—EP1C12Q240C8 as control unit.The Cyclone belongs to SoPC Series—E-Play1c12.Besides,the system also includes DC electric machineries,photo electricity sensors,ultrasonic sensors,power supply circuits and other circuits.The dolly is controlled to locomote along the black line in track-seeking zone and to accelerate or decelerate in special zone.In the light-seeking zone,the dolly is guided by lamp-house to locomote and stops at the end line.Meanwhile,the lattice LCD located in the head of the dolly shows the time and distance of the locomotion.
