Control system and method of intelligent wheelchair

Abstract

The invention relates to a control system of an intelligent wheelchair. The control system comprises a wheelchair motion control subsystem and a man-machine interaction control subsystem. The wheelchair motion control subsystem at least comprises a wheelchair body, and a waist training mechanism of a single-degree-of-freedom six-bar mechanism contained in the wheelchair body can simulate the sitting-down and standing-up tracks of a healthy person so as to exercise the waist of a user. The man-machine interaction control subsystem at least comprises a sensor module, a mobile terminal and a data processing cloud terminal, and the man-machine interaction control subsystem collects training data of the user through the sensor module arranged on the wheelchair body and transmits the training data of the user to the data processing cloud terminal through the mobile terminal via a wireless network for data processing so as to achieve man-machine interaction between the user and the intelligent wheelchair. The control system of the intelligent wheelchair can collect the latest training data of the user constantly and feed back the training speed and training advice in time so as to achieve man-machine interaction.

Description

technical field [0001] The invention relates to an intelligent wheelchair, in particular to a control system and a control method of the intelligent wheelchair. Background technique [0002] Surveys show that there are about 50 million stroke patients in the world every year, and only one new stroke patient is added every 21 seconds in China. According to the survey of some populations in some provinces and cities in 2012, the prevalence of stroke in my country is about 1.82%, and 85% of stroke patients need physical rehabilitation. In addition, due to living habits and other reasons, the incidence of stroke is tending to be younger, and people aged 40-50 have gradually become the main incidence group. Researches on stroke all over the world are constantly going on, and these studies aim to restore the original physical fitness of patients with the greatest possibility. Although traditional rehabilitation services can play a certain role, they are not the best choice for p...

Problems solved by technology

[0005] Although the control system of the patented smart wheelchair can realize natural human-computer interaction, the patented smart wheelchair can only be used as a means of transportation for the elderly and the disabled, and it is difficult to achieve the exercise function through the smart wheelchair provided by the patent

On the other hand, the power-assisted equipment based on a single training method in the prior art cannot well realize the concept of human-computer interaction, nor can it understand the training process through information exchange with the user, so as to adjust the training plan in time

For users with different needs, traditional rehabilitation wheelchairs are difficult to coordinate, and the number and intensity of daily training of users vary from person to person, and the progress of rehabilitation is constantly changing. Traditional rehabilitation wheelchairs obviously cannot meet the needs
