Embodiment 1

[0045] This embodiment provides an intelligent wheelchair control system based on a brain-computer interface, including: a power management unit, a signal input unit, a system main control unit, and a motion execution unit. The unit is connected with the main control unit of the system, the signal input unit is connected with the main control unit of the system, and the main control unit of the system is connected with the motion execution unit.

[0046] Further, the signal input unit includes: an environment detection sensor module, an EEG signal acquisition module and an attitude detection sensor module, wherein,

[0047] -The environment detection sensing module includes: a body sensor and a laser range finder, wherein the body sensor is used to sense the location characteristics of the environment ahead, and the laser range finder is used to detect obstacles ahead;

[0048] - The EEG signal acquisition module includes: an EEG signal amplification box and an EEG signal main...

Embodiment 2

[0081] This embodiment provides a brain-computer interface-based intelligent wheelchair, including the brain-computer interface-based intelligent wheelchair control system provided in Embodiment 1.

[0082] The above two embodiments are specifically:

[0083] Such as figure 1 As shown, the power management unit in the above two embodiments includes: a 24V lead storage battery, a 19V voltage stabilizing module, and a 12V voltage stabilizing module. The power supply of the wheelchair system is provided by the 24V battery, no external power supply is required, which provides the mobility characteristics necessary for wheelchairs. The 24V lead storage battery is composed of two 12V lead storage batteries connected in series. For parts with different rated voltages, since the power supply voltages of different modules are different, the body sensor, industrial computer and display screen are powered by the 12V voltage stabilizing module. The control box is powered by a 19V voltag...

Abstract

The invention provides an intelligent wheelchair based on a brain-computer interface and a control system and a control method of the intelligent wheelchair. The control system comprises a power supply management unit, a signal input unit, a system master control unit and a motion executing unit, the power supply management unit is respectively in circuit connection with the signal input unit, the motion executing unit and the system master control unit, the signal input unit is in communicating connection with the system master control unit, and the system master control unit is in communicating connection with the motion executing unit. The control system is a modularized intelligent control system, the intelligent wheelchair using the intelligent control system has the functions of automatically walking, being a barrier, being controlled by brain electrical signals to walk, carrying out local path plans and the like, the advantage of the more flexible and more reliable operation mode is achieved, the requirements of the old with dyskinesia or amyotrophy, the disabled and other crowds can be met, and the life quality of the old with the dyskinesia or the amyotrophy, the disabled and other crowds is improved.

Description

technical field [0001] The invention relates to a control system in the technical field of wheelchairs, in particular to an intelligent wheelchair based on a brain-computer interface and its control system and control method. Background technique [0002] With the development and progress of social civilization, ensuring and improving the quality of life of vulnerable groups such as the elderly and the disabled has received more and more attention from people from all walks of life. A large number of studies have shown that it can effectively enhance the mobility of the elderly and the disabled. , not only makes their lives more convenient, but also has a profound impact on their mental health, self-evaluation, and mental state. The current wheelchairs that can be used by such vulnerable groups generally require manual operation of operating levers or buttons, which is difficult for patients with severe motor function or elderly people who have lost motor function. [0003]...
