毕业设计(论文)基于单片机的智能小车设计Design of the Smart Car Based on SCM摘 要本寻迹小车是以自己制作的小车作为车的车架,80c51 单片机为控制核心,加以步进电机、光电传感器和电源电路以与其他电路构成
系统由 80c51 通过IO 口控制小车的前进后退以与转向
在该系统中,由红外光电传感器实现路径识别,通过对小车速度的控制,使小车能根据任意给定的黑色引导线平稳地寻迹
实验证明:系统能很好地满足寻迹小车对路径识别性能和抗干扰能力的要求,速度调节响应时间快,稳态误差小,具有较好的动态性能
关键词80c51 直流电机 光电传感器 自动寻迹小车Abstract:The smart car is aluminum alloy for the chassis, 80c51 MCU as its core, including stepper motor, plus photoelectric sensors, as well as other flame sensor and power circuit
MCU controls the car turning back forward or running on the white line
RPR220 reflective photo sensor seeks the trace
Far infrared flame sensor tracks the flame
In addition, the SCM system with Sunplus for voice broadcast can remind current status
The system transmits information through DF module
The car’s status will
