An intelligent learning wheelchair and its voice learning method

Abstract

The invention relates to an intelligent learning wheelchair and a voice learning method thereof. An intelligent learning wheelchair of the present invention includes a wheelchair body, a seat, armrests arranged on both sides of the seat, a universal wheel set connected by a support frame at the front under the seat, and a wheel set for rotating the direction of the universal wheel set. Steering mechanism, active wheel set arranged under the seat and connected through a support frame at the rear, and a driving mechanism for driving the active wheel set; obstacle avoidance system, located under the seat; voice learning system including voice receiving system, voice recognition module, A / D converter and memory; the collecting device is provided with a voice learning button; the voice learning button can transmit the voice command collected by the collecting device to the voice receiver and can perform voice learning; the control system includes a central processing device's microcontroller. The present invention can use the voice command to control the running of the own wheelchair, can carry out voice learning and recognition accurately, and can automatically run and avoid obstacles.

Description

Technical field [0001] The present invention relates to the field of electromechanical integration applications, and more particularly to an intelligent learning wheelchair and its speech learning methods. Background technique [0002] Throughout the market, wheelchairs now can be roughly divided into two categories: manual wheelchairs and electric wheelchairs. Nowadays, the general wheelchair in society requires people's power to move them. It is roughly a chair shape, four wheels, rear wheels, plus a hand push wheel, and the brake is also added to the rear wheel, the front wheel is small, Used to turn, add a preventive row in the back of the wheelchair.

Problems solved by technology

The disadvantage of this offline training method is that when applying such a model to a real system, the target label cases do not match well with the cases in the source domain, and sometimes are completely different, making the model training fail

There are still problems with the application of this method to the use of wheelchair phonics learning
