基于单片机的辅助站立轮椅的设计

The Design of Auxiliary Standing Wheelchair Based on Single Chip Computer

为解决行动有障碍却无人照顾的问题,本文以STM32F103单片机为控制核心,并以速度传感器、推杆行程传感器、步进电机驱动为执行机构,实现了对电动轮椅的辅助站立以及自动避障功能。其中电动推杆实现轮椅辅助站立姿态和座椅姿态的转换。霍尔速度传感器实时测量和监控轮椅速度、加速度。该轮椅具有辅助站立、电机驱动及红外避障等功能,对比市面上的普通电动轮椅具有明显的优势。

In order to solve the problem that there are obstacles but no one to take care of,the team designed the STM32F103 single chip microcomputer as the control core,and the speed sensor,push rod travel sensor,stepper motor drive as the actuator to realize the auxiliary standing and automatic obstacle avoidance function of the electric wheelchair.Among them,the electric push rod realizes the conversion of wheelchair assisted standing posture and seat posture.Hall speed sensor measures and monitors wheelchair speed and acceleration in real time.The wheelchair has the functions of auxiliary standing,motor driving and infrared obstacle avoidance,which has obvious advantages compared with the ordinary electric wheelchair on the market.
