Electrocerebral-drive high-reliability control system based on dual-mode check mechanism

Abstract

The invention discloses an electrocerebral-drive high-reliability control system based on a dual-mode check mechanism. The system comprises a signal acquisition module, an impedance detection module, a parameter setting module, a signal processing module, a target check module and a human-machine interaction module, wherein the impedance detection module and the parameter setting module are used for initializing the system; the signal processing module comprises a time-domain component signal processing module and a frequency-domain component signal processing module; the target check module comprises a check code encoder and a check code decoder and is used for performing error check and correction operations on the target key preliminary judgment result deduced from the dual-mode joint characteristics of the electrocerebral time-domain component calculated by the signal processing module; the human-machine interaction module comprises a control state display module and a visual stimulation module; the control state display module is used for receiving the target key coordinates output by the target check module, and displaying the system operation state after the operation of the target key so as to form visual feedback; and the visual stimulation module is used for continuously applying stimulus and inputting the next control command. The system disclosed by the invention has the advantages of simple structure and the like, is convenient to operate and can increase the control speed as well as the control reliability and accuracy.

Description

technical field [0001] The invention mainly relates to the technical field of brain-computer interface, in particular to a highly reliable control device driven by brain electricity designed based on a dual-mode verification mechanism. Background technique [0002] A system that controls specific equipment through certain operations can be called a control system. For example, the use of home appliances such as computers, TVs, and air conditioners, the control of smart wheelchairs, and the driving of aircraft and other weapons and equipment all need to be realized through the control system. At present, the control system is widely used in home appliance control, medical assistance to the disabled, and aircraft driving in the military aerospace field. In recent years, the development and application of remote control devices have met the needs of remote control of the environment, and brought great convenience to the control of control scenes that are inaccessible or inconv...

Problems solved by technology

[0005] The above-mentioned control systems driven by single-modal EEG components can improve the reliability of the system to a certain extent by increasing the stimulation time, but the multiplied increase in the target selection time makes it more difficult for the system with poor real-time performance to meet practical applications.
