Embodiment 1

[0060] see figure 1 as well as figure 2 , This embodiment provides an electric smart wheelchair controlled by electro-oculogram and lip movement signals. The wheelchair is an electric intelligent wheelchair controlled by LabView-based electro-oculogram and lip movement signals, and adopts bipolar leads to collect electro-oculogram signals. Wherein, the wheelchair includes a wheelchair mechanism, a signal acquisition device 1, a signal acquisition device 2, 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, etc.

[0061] 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...

Embodiment 2

[0096] see Figure 11, this embodiment provides an electric smart wheelchair controlled by electro-oculogram and lip movement signals. 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 ra...

Embodiment 3

[0099] This embodiment provides an electric smart wheelchair controlled by electro-oculogram and lip movement signals, 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 ...

Abstract

The invention discloses an electric intelligent wheelchair controlled by electro-oculogram signals and lip action signals and a control method. The system comprises a wheelchair mechanism, a signal acquisition device I, a signal acquisition device II, a signal processing device and a wheelchair motion control device, wherein the signal acquisition device I comprises a bipolar lead electrode patchassembly and a signal acquisition module I; the signal processing device comprises a feature extraction module and a pattern recognition module, wherein the feature extraction module is used for extracting waveform features of the electro-oculogram signals, and the pattern recognition module is used for firstly acquiring each piece of characteristic information of the waveform characteristics, andthen comparing each piece of characteristic information with each preset recognition parameter in a preset recognition pattern to determine a motion mode corresponding to the waveform characteristics; and the wheelchair motion control device is used for driving a wheelchair body to move according to the motion mode determined by the pattern recognition module. The intelligent wheelchair can be accurately controlled through the electro-oculogram signals, real-time performance is good, extraction is more reliable, parameter adjustment is easy and convenient, applicability is high, operations are easy, and adjustment is convenient.

Description

technical field [0001] The present invention relates to an electric intelligent wheelchair in the technical field of wheelchairs, in particular to an electric intelligent wheelchair controlled by eye electricity and lip movement signals, and also relates to an electric intelligent wheelchair control method controlled by eye electricity and lip movement signals. 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 co...
