With the aging of the population and the pursuit of an improved quality of life among the disabled,the user requirements for wheelchair function have become diversified and intelligent.To improve the ability of wheelchair users to care for themselves and be independent,this paper proposes an intelligent wheelchair control system.The system is controlled by an STM32 single-chip microcomputer.It adopts modular and systematic design.The power module,rocker module,obstacle avoidance module,and drive module form an organic whole.The modules work together and coordinate with each other to form a safe and reliable wheelchair control system.The transmission and reception of data between modules are realized by a communication module.The wheelchair is designed to operate under both manual and automatic control,which the wheelchair user can exploit to live independently without care from others.The operation of the wheelchair is safe and reliable.
