Embodiment Construction

[0064] The present invention is described in detail below in conjunction with accompanying drawing.

[0065] refer to figure 2 , an intelligent brain-controlled manipulator-assisted feeding system for upper-limb disabled persons, including four modules of human-computer interaction interface module A, signal acquisition module B, signal processing module C and manipulator feeding module D.

[0066] The human-computer interaction interface module A is used to provide a platform for information interaction between the user and the computer system, in which the user can set the positions of food and auxiliary objects. According to the three-dimensional space format, adjust the positions of food and auxiliary objects. The distance of each adjustment is 1cm. The robotic arm moves to the corresponding position, and the adjusted XY plane position is displayed in the upper right corner of the human-computer interaction interface. Click the "Start feeding" button to enter the steady-...

Abstract

The invention discloses an intelligent brain-controlled mechanical arm auxiliary feeding system and method for disabled people. A human-computer interaction interface module is used for providing a platform for information interaction between a user and a computer system; a signal acquisition module is used for acquiring electroencephalogram data (SSVEP) induced by stimulation stroboflash on a steady-state visual stimulation interface; a signal processing module is used for preprocessing and classifying electroencephalogram signals acquired by the signal acquisition module and converting a classification result into a control instruction; a mechanical arm feeding module is used for identifying the control instruction transmitted by the signal processing module through a USB serial port and driving a mechanical arm to complete auxiliary feeding of corresponding food according to the control instruction; the SSVEP is induced through the stimulation of square flicker on a liquid crystal display screen, meanwhile, the SSVEP is effectively classified through an FBKCCA algorithm, electroencephalogram signals generated when a person with the upper limb disability watches flicker stimulation of different frequencies are processed, and the classification accuracy is higher.

Description

technical field [0001] The invention relates to a medical assistance system, in particular to an intelligent brain-controlled manipulator assisted eating system and method for disabled people. Background technique [0002] In the past 20 years, with the increase of the elderly population, the incidence of stroke and other diseases in my country has generally shown an upward trend. To a certain extent, these diseases can lead to impairment of the motor function of one side of the patient, which greatly affects the daily life of the patient. They cannot complete activities such as dressing and eating, and in severe cases, they completely lose their ability to take care of themselves. Often, such patients must be attended to at all times to help them with daily activities. This will increase the economic pressure and mental pressure on the patient's family. At the same time, for patients, the reality that they have to rely on others to complete their lives for a long time has...
