Problems solved by technology

[0003] Existing studies have shown that it is difficult for operators to maintain a stable mental state for a long time in actual work, especially in man-machine systems with high performance, it is difficult for operators to maintain a relatively stable and suitable work mentality for a long time in the process of variable load work State, and changes in mental state will cause changes in behavior, which will have a greater negative impact on work performance and safety during the work process

Embodiment Construction

[0037] The present invention is described in further detail below in conjunction with accompanying drawing:

[0038] see figure 1 , the present invention utilizes EEG signals to monitor the user's mental state, uses a portable EEG cap to wear on the user's head, picks up human scalp EEG signals, and uses signal feature extraction and pattern recognition to judge the user's mental state Method; the device specifically includes: a brain electrode and its EEG cap, an EEG acquisition module, a signal processing and storage module and a display module. The EEG acquisition module includes an EEG acquisition unit and a wireless communication unit; the signal processing and storage includes a preprocessing unit, a feature extraction unit, a pattern recognition unit, a state calculation unit and a management storage unit; the display module includes a display.

[0039] The EEG acquisition module adopts a portable EEG cap neuracle with integrated wireless communication unit, and the di...

Abstract

The invention discloses a device and method for monitoring a mental state of a user by utilization of EEG signals. The device comprises an EEG acquisition module, a signal processing module, a storagemodule and a display module. The EEG acquisition module, the storage module and the display module are all interacted with the signal processing module. To solve the problem that a manipulator is difficult to keep a stable mental state in actual work, the mental state of the manipulator is monitored in real time by utilization of the EEG signals of the manipulator, the mental state of the manipulator is displayed and stored in real time through a manipulator mental state monitoring and evaluation method, when the mental state of the manipulator is poor, the manipulator is early warned and prompted, and an effective determining basis and method can be provided for quantified monitoring and working early warning of the mental state of the manipulator.

Description

technical field [0001] The invention belongs to the technical field of mental state identification, and relates to a device and method for monitoring a user's mental state by using electroencephalogram signals. Background technique [0002] Mental state is a comprehensive expression of human psychology, emotion and brain state, which has an important impact on individual learning, memory and decision-making. Spirituality is the source of individual differences and is a key component of many personality traits and psyches. With the development and improvement of the level of artificial intelligence, although the reliability of artificial intelligence technology has reached an unprecedented height, the supervision and decision-making role of the operator is still irreplaceable, and the operation of artificial intelligence technology requires the supervision and decision-making of the operator , and the role of the manipulator is constantly tending to high-level supervision an...
