Embodiment 1

[0058] see figure 1 as well as figure 2 , this embodiment provides an eye-electric smart wheelchair. The wheelchair is an oculoelectric smart wheelchair based on LabView, and adopts bipolar leads to collect oculoelectric signals. Wherein, the wheelchair includes a wheelchair mechanism, a signal acquisition device, a signal processing device, and a wheelchair motion control device. The communication methods between these devices can adopt existing communication methods, such as Bluetooth, WiFi, serial ports, and the like.

[0059] The wheelchair mechanism includes a wheelchair body and a motor. The motor is installed on the wheelchair body and is used to drive the wheelchair body to move. The wheelchair mechanism can be an existing electric wheelchair, which can move in various terrains through electric drive. Of course, in some embodiments, the wheelchair mechanism can also be other wheelchairs that can move under the support of external power.

[0060] see image 3 and ...

Embodiment 2

[0092] see Figure 11 , this embodiment provides an oculoelectric intelligent wheelchair, and the system refines the specific recognition process of the pattern recognition module on the basis of Embodiment 1. Wherein, the pattern recognition module judges whether the maximum value in the waveform feature is within a preset range one. When the maximum value is within a preset range 1, the pattern recognition module judges whether the minimum value in the waveform feature is within a preset range 2. When the minimum value is within the second preset range, the pattern recognition module determines that the movement mode is turning right. When the maximum value is not within the preset range one, the pattern recognition module determines whether the maximum value is within a preset range three. When the maximum value is within a preset range three, the pattern recognition module determines whether the minimum value is within a preset range four. When the minimum value is with...

Embodiment 3

[0095]This embodiment provides an eye-electric intelligent wheelchair, and the system further adds the following steps on the basis of Embodiment 1. Wherein, the pattern recognition module judges whether the maximum value in the waveform feature is within a preset range one. When the maximum value is within a preset range 1, the pattern recognition module judges whether the minimum value in the waveform feature is within a preset range 2. When the minimum value is within the second preset range, the pattern recognition module determines that the movement mode is turning right. When the maximum value is not within the preset range one, the pattern recognition module determines whether the maximum value is within a preset range three. When the maximum value is within a preset range three, the pattern recognition module determines whether the minimum value is within a preset range four. When the minimum value is within the preset range four, the pattern recognition module deter...

Abstract

The invention discloses an electro-oculogram intelligent wheelchair and a control method thereof. The electro-oculogram intelligent wheelchair comprises a wheelchair mechanism, a signal acquisition device, a signal processing device and a wheelchair motion control device. The signal acquisition device comprises a bipolar lead electrode patch assembly and a signal acquisition module. The signal processing device comprises a feature extraction module and a mode recognition module. The feature extraction module is used for extracting waveform features of electro-oculogram signals. The mode recognition module is used for firstly acquiring various feature information of waveform features, and then comparing various feature information with various preset recognition parameters in a preset recognition mode to determine a motion mode corresponding to the waveform features. The wheelchair motion control device is used for driving the wheelchair body to move according to a motion mode determined by the mode recognition module. The electro-oculogram intelligent wheelchair can accurately control the intelligent wheelchair through the electro-oculogram signals, and has good real-time performance, more reliable extraction, simple and convenient parameter adjustment, strong applicability, simple operation and convenient adjustment.

Description

technical field [0001] The present invention relates to a wheelchair control system in the technical field of wheelchair control, in particular to an eye-electric intelligent wheelchair, and also relates to an eye-electric intelligent wheelchair control method. Background technique [0002] People with disabilities are socially disadvantaged and make up a large portion of our population. There are many people with physical disabilities, which has caused serious difficulties for their survival and development. Although the state has introduced a series of guidelines and policies in terms of social security for the disabled, modern people's concept of the disabled has gradually become popular, and humanitarian care has gradually gained popularity. But it is difficult to give them enough help in specific aspects of life. Unfortunately, people with physical disabilities are confined to a small place and cannot freely enjoy the fun of outdoor activities. The problem of populat...
