摘要
随着社会的发展和人类文明程度的提高,人们特别是残障人士愈来愈需要运用现代高新技术来改善他们的生活质量和生活自由度。因此,对用于帮助残障人行走的机器人轮椅研究已逐渐成为热点。设计了一款以单片机为主控制器的多功能智能轮椅。单片机拟采用低功耗微控制器STM32F103,其能为外部设备提供稳定的PWM波,主要用于控制步进电机的转速,并且还负责超声波模块和红外测距传感器反馈的信号;此外,单片机还负责向步进电机的驱动模块等器件发送信号。配备的GPS定位系统可准确地获取使用者的地理位置。温度传感器可实现对使用者体温的监测,心率血氧监测传感器可实时监测心率健康状况,如出现异常可向监护人发出远程警报提示。
With the development of society and the improvement of human civilization,people,especially the disabled,need to use modern high technology to improve their quality of life and freedom of life.Therefore,the research on robotic wheelchairs used to help disabled people walk has gradually become a hot spot.A multi-functional intelligent wheelchair with a single-chip microcomputer as the main controller is designed.The single-chip microcomputer is intended to use a low-power microcontroller STM32F103,which can provide stable PWM waves for external devices,and it is mainly used for the speed control function of the stepper motor,and is also responsible for the ultrasonic module and infrared ranging sensor feedback signal.In addition,the single-chip microcomputer is also responsible for sending signals to the drive module of the stepper motor and other devices.And the equipped GPS positioning system can accurately obtain the geographic location of the user.The temperature sensor can monitor the user’s body temperature,the heart rate blood oxygen monitoring sensor can monitor the heart rate health status in real time,and a remote alarm can be sent to the guardion if an exception occurs.
