Abstract
本文提出了一种基于51单片机的室内目标定位并反馈指导电机控制的方案。采用红外线触发，超声波测距，三点定位技术，使用51单片机结合L298N电机驱动芯片来控制步进电机和单相直流电机，实现了电风扇自动跟踪目标和自动调速的功能。 In this essay, a system of indoor object locating and feedback motor controlling based on single chip is introduced. The method has realized the goal of automatic tracking and automatic speed control for the electric fan by using the technologies including infrared trigger, ultrasonic ranging and three-point localization, and using MCU with L298N chip to control stepper motor and single- phase DC motor.
