Motion imagery control-based wheelchair for disabled people

Abstract

The invention relates to a motion imagery control-based wheelchair for disabled people, which belongs to the technical field of mechanical engineering. In the motion imagery control-based wheelchair for the disabled people, a wheelchair frame serves as a skeleton; an accommodating shelf is embedded between two handrails on the wheelchair frame; a rear suspending box is welded at the back of a backrest of the wheelchair frame; a lateral suspending box is welded on the side of the right handrail and levels with the upper surface of the handrail; a command control system is arranged on the rear suspending box and the accommodating shelf; a chip of an executive system is arranged in the lateral suspending box; a service box is welded on a frame under a wheelchair seat on the wheelchair frame; the command control system outputs a wheelchair control command to the executive system; and the executive system executes the motion control command of the wheelchair. The motion imagery control-based wheelchair for the disabled people has the advantages that: a controller of the wheelchair can control the motion of the wheelchair directly by utilizing the motion imagery of the brain, without using limbs to control; a control signal can be generated quickly; and the independent motion capacity of the disabled people and patients with dyskinesia can be improved with the help of the wheelchair, so that the daily independent living capacity can be improved and the life quality can be improved.

Description

technical field [0001] The invention relates to a wheelchair in the technical field of mechanical engineering, in particular to a wheelchair for disabled persons based on motion imagery control. Background technique [0002] As the degree of aging increases, the total number of elderly people increases sharply, accompanied by the problem that the number of people suffering from physiological function decline and osteoarthritis is also increasing. In addition, the large number of car accidents that occur every year is also an important reason for the increase in the number of disabled people. For patients with sound upper limbs and disabled lower limbs, the wheelchair can be controlled by the joystick, but it is powerless for people with disabled upper limbs. In recent decades, the control based on brain-computer interaction technology has received a lot of attention from researchers and has become one of the research hotspots. Brain-computer interaction technology refers t...

Problems solved by technology

But their proposed method takes several seconds to generate a new control command, which is relatively slow

In addition, the path of wheelchair movement must be pre-set, and it cannot be moved arbitrarily according to the wishes of the wheelchair controller at that time
