| Abstract: With the increasing aging population in China, the market demand for electric wheelchairs and even smart wheelchairs is gradually increasing. This paper proposes to implement the automatic balance function of the wheelchair seat plane within a certain range based on STM32 single-chip microcomputer. The design also integrates many other practical functions, including positioning information sending and receiving, human physiological information monitoring, joystick control, wheelchair braking, ultrasonic obstacle detection and other Internet of Things functions. A WeChat applet for relatives is also developed. The system performs attitude data settlement through the digital motion processor, outputs the control torque of the balanced motor, and realizes the automatic adjustment of the seat plane. After an extensive market research, the proposed automatic balance function has been well received by users, which effectively fills the gap in the market of the smart electric wheelchair. |
