Method for controlling wheelchair by voice

Abstract

The invention discloses an intelligent wheelchair, and relates to the field of control. The wheelchair is used for solving the problem in the prior art that people with disabled hands cannot control the wheelchair through a handle. The method comprises the following steps that a received sound signal is analyzed, key words carried in the sound signal are obtained, and the key words and a stored control command are matched; after matching, the determined first control command is played through a player and used for controlling the wheelchair; within a set time threshold value, when a triggeringcommand is received, the first control command is sent to a driver of the wheelchair.

Description

technical field

[0001] The invention relates to the technical field of intelligent control, and more specifically relates to a method for controlling a wheelchair by voice. Background technique

[0002] With the development of society and the improvement of human civilization, people, especially the disabled, increasingly need to use modern high-tech to improve their quality of life and freedom of life. Because of various traffic accidents, natural and man-made disasters and various diseases, tens of thousands of people lose one or more abilities (such as walking, hands-on ability, etc.) every year. Therefore, research on robotic wheelchairs for helping disabled people to walk has gradually become a hotspot.

[0003] Existing wheelchairs mainly realize functions such as moving forward, turning, retreating and stopping by handle control. Considering that most wheelchair users are handicapped, if the wheelchair user happens to have hand disabilities, the wheelchair controlle...
