Abstract

The invention discloses an intelligent wheelchair voice drive controller and an identification and control method. The controller includes an audio circuit module, a voice processing circuit module, a MAX232 communication module, a DSP processor, a joystick circuit module, a speed regulation circuit module, Power supply circuit module, motor drive circuit module, fault detection circuit module, voltage and current detection circuit module, brake circuit module. Speech recognition adopts a specific human speech recognition method based on fuzzy support vector machine, which improves the recognition rate and enhances the anti-noise ability. The DSP processor controls the coordinated operation of the motor by outputting PWM waves. The invention proposes a master-slave intelligent wheelchair voice drive control scheme with a single-chip microcomputer as a voice information processor and a DSP as a drive controller. The advantage of the present invention is that it can be controlled manually or automatically by voice, and it is convenient to use.

Description

technical field [0001] The invention relates to an intelligent wheelchair voice drive controller and a recognition and control method, belonging to the fields of voice recognition and motor drive control of intelligent wheelchairs. Background technique [0002] With the development and progress of social civilization, ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has attracted more and more attention from people from all walks of life. As an auxiliary means of transportation, the wheelchair will have an increasing demand whether it is an elderly person or a person with a congenital or acquired disability or disability. The electric wheelchair is suitable for the elderly and infirm with lower limb disabilities and inconvenient walking, and is an ideal means of transportation. For people with severe disabilities and inability to move their upper limbs, smart wheelchairs provide great convenience for their lives. [0003]...
