Abstract

The invention discloses a multimodal wheelchair brain control system and method based on a cloud platform. The multimodal wheelchair brain control system totally includes three modals to achieve parallel control on a wheelchair; the first modal is motion imagination control, the second modal is steady state vision induction control, and the third modal is voice control. In the aspect of monitoringof the cloud platform, by automatically putting up an MYSQL server, electroencephalogram data of a user and the running conditions of the wheelchair are monitored. A GSM module is carried on an FPGAthrough a serial port, and data is uploaded to the server through 4G network or WIFI. When the user logs in to a webpage which is independently developed by JSP+HTML+CSS, the wheelchair and the user conditions can be remotely monitored.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a multi-modal wheelchair brain control system and method based on a cloud platform. Background technique [0002] Human-computer interaction is one of the important research topics today, especially the rapid development of virtual reality technology, which has greatly improved human-computer interaction technology, and has attracted more and more attention from humans in the fields of rehabilitation medicine, industry, and military affairs. . The Brain-computer Interface (BCI) takes people as the center of interaction, which greatly improves the efficiency of human-computer interaction. Brain wave control belongs to an intelligent technology, through the electrical signal sent by the brain, and the brain-computer interface technology is used to realize the control of external objects. Evoked potentials are specific activities generated by the nervous system receiving inter...
