基于STC89C51单片机的多功能智能小车设计

设计一种以STC89C51单片机为控制核心，具备避障、循迹和遥控功能的智能小车。使用光电开关检测障碍，通过控制电机转向来进行壁障；使用红外传感器寻找线路，控制智能小车自行循迹；使用红外遥控器实现前进、后退、向右、向左、停止和发动功能。小车由底盘、传感器和车载电路组成，车载电路包括电源、单片机最小系统和驱动。系统采用了模块化设计方法，结构简单，可靠性高。

Design of multifunctional smart car based on STC89C51 MCU

This paper presents the design of a smart car based on STC89C51 MCU, which can avoid obstruction, track and be remotely controlled. The photoelectric switch can detect barriers, and carry out it by driving the motor steering. The infrared sensors can find the line and let the car ran from it. Using infrared signal, the car can also be remotely controlled to forward, back, turn right, turn left, stop and start. The car includes the chassis, the sensors and the vehicle electric circuits. The electric circuits includes the batteries, the MCU and the driving part. The overall system ulilizes modularization designing, which is simple, but reliable.
