基于步进电机的自动控制升降旗系统设计

Design of Automatic Control Flag Hoist System Based on Stepper Motor

为了实现自动控制国旗的升降,本文设计了一种基于单片机和步进电机的自动控制升降旗系统。设计采用STM32单片机作为核心处理器,采用28BYJ-48永磁式步进电机提供动力,电机驱动使用ULN2003大电流高压驱动芯片,采用LCD1602显示旗帜高度。经测试,本系统结构简单、可靠性高。

In order to achieve automatic control flag hoist, this paper designs the automatic control movements flag system based on microcontroller and the stepper motor. Design uses STM32 microcontroller as the core processor, use 28BYJ-48 permanent magnet stepper motors for power, motor drive using ULN2003 high-current high-voltage driver, using LCD1602 display banner height. After testing, the system is simple with high reliability.
