Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments. The following descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention to other forms. Changes to equivalent embodiments with equivalent changes. Any simple modifications or equivalent changes made to the above embodiments according to the technical essence of the present invention without departing from the solution content of the present invention fall within the protection scope of the present invention.

[0018] When the human brain performs different imaginative movements, the different imaginative movements of the brain will lead to different active areas of the brain, and at the same time, the content of oxygenated hemoglobin will also be different. Different brain functional areas respond differently on brain near-infrared spectroscopy.

[0019] Such as figure 2 As shown, the two kinds of hemoglobin have a...

Abstract

The invention relates to a wheelchair control system based on detection of brain near-infrared function information. The system comprises a near-infrared collection unit, a control unit, a computer processing unit, a wireless transmission unit and a motor driving unit, wherein the output end of the near-infrared collection unit is connected with the input end of the control unit, the output end of the control unit is connected with the input end of the computer processing unit, the output end of the computer processing unit is connected with the input end of the wireless transmission unit, and the output end of the wireless transmission unit is connected with the input end of the motor driving unit. The system has the advantages that the brain movement function areas and four movement emotions, such as imagination of the left hand, imagination of the right hand, imagination of the left foot or imagination of the right foot, are recognized, and the different contents of aerobic hemoglobin and deoxygenated hemoglobin are detected, so the recognition purpose is realized, and a control instruction is sent; the cost is low, the resolution is high, and the operability is high.

Description

technical field [0001] The invention relates to an intelligent wheelchair system, in particular to a wheelchair control system based on brain near-infrared function information detection. Background technique [0002] As a service auxiliary exercise tool in the field of medical care, smart wheelchairs can help the disabled and the elderly to acquire the ability to take care of themselves and work, and integrate into society. The existing wheelchair control system based on motor imagery is mainly aimed at the EEG signal of the scalp, and uses the EEG signal to extract movement instructions. However, although the EEG signal has a high temporal resolution, the spatial resolution of this detection method is limited. Very low indeed. Moreover, the cost is high, and the detection signal is unstable. In the EEG-based control wheelchair system, because most of them need to collect EEG signals, the electrodes used are Ag / Agcl electrodes, and the conductive glue in the electrodes ge...
