摘要
利用树莓派软件设计并开发了一种WiFi环境下的遥控多功能轮椅床,智能手机作为多功能轮椅的主要控制终端,以树莓派为基础作为该多功能轮椅床的核心控制器,其中控制系统的程序采用Python语言进行开发。树莓派对舵机的控制可实现多功能轮椅床的转换变形,同时树莓派对电机的控制实现多功能轮椅的移动,通过超声波测距模块可以实时监测多功能轮椅与周边的情况,实现相应的自主避障功能。该多功能轮椅主要由轮椅床底盘模块、电机驱动模块和超声波测距等多个功能模块构成。多功能轮椅与智能手机之间的通信方式采用WiFi通信,用户能够使用智能手机远程遥控来实现多功能轮椅的转换变形、移动和避障等。
Using Raspberry Pi software to design and develop a remote control multifunctional wheelchair bed under WiFi environment,the smartphone is the main control terminal of the multifunctional wheelchair,and the Raspberry Pi is used as the core controller of the multifunctional wheelchair bed.The program of the control system is developed using Python language.The control of the raspberry party steering gear can realize the transformation and deformation of the multifunctional wheelchair bed.At the same time,the control of the raspberry party motor can realize the movement of the multifunctional wheelchair.The ultrasonic ranging module can monitor the situation of the multifunctional wheelchair and its surroundings in real time to achieve the corresponding autonomous obstacle avoidance function.The multifunctional wheelchair is mainly composed of multiple functional modules such as a wheelchair bed chassis module,a motor drive module,and ultrasonic ranging.The communication method between the multifunctional wheelchair and the smartphone uses WiFi communication,and users can use the smartphone to remotely control the transformation,movement,and obstacle avoidance of the multifunctional wheelchair.
