Wheelchair control method based on brain waves and wheelchair control system combined with voice

Abstract

The invention discloses a wheelchair control method based on brain waves and a wheelchair control system combined with voice. According to the wheelchair control method, filtering, feature extractionand signal classification are performed on the acquired brain waves and then the brain waves are converted into wheelchair control signals to control wheelchair movement. The wheelchair control systemcomprises a wheelchair movement motor, a processor module, a voice module, a motor driving module, an obstacle detection module, a road condition detection module and a first communication module group. The wheelchair control system also comprises a brain wave acquisition device and a terminal control device. The brain wave detection device comprises a brain wave acquisition and processing moduleand a second communication module. The terminal control device comprises a mobile phone and a server. The wheelchair user is enabled to control wheelchair movement through the brain waves, the voiceor the manual mode, the wheelchair control consciousness of the wheelchair user can be converted into the voice information and the obstacle and road condition detection and broadcasting can be performed in the wheelchair movement process so that the automation, the intellectualization, the safety and the reliability of wheelchair control can be enhanced.

Description

technical field [0001] The invention belongs to the field of transportation tools suitable for patients or disabled persons, and in particular relates to a wheelchair control method based on brain waves and a wheelchair control system combined with voice. Background technique [0002] Wheelchairs are an important travel tool for the elderly, patients, or disabled people with limited mobility.
