Problems solved by technology

Existing research on manipulators mainly focuses on how to improve the manipulator’s ability to work for a long time, but there are few studies on the influence of manipulators’ personal mental state changes on system performance due to environmental stimuli and changes in personal mental state.

Embodiment Construction

[0034] The present invention is described in further detail below in conjunction with accompanying drawing:

[0035] see Figure 1-3 , the EEG analysis of the manipulator's mental state and its manipulation compensation method of the present invention, comprising the following steps:

[0036] 1) According to the needs of the operator, set the arrangement position of the EEG electrodes of the EEG acquisition module, wear the EEG acquisition module for the operator, and the EEG acquisition module collects the EEG signals of the operator at work in real time, and transmits The collected EEG signals are wirelessly transmitted to the EEG signal analysis module;

[0037] The EEG signal analysis module analyzes the EEG signals obtained in the step 1); firstly, performs preprocessing such as filtering, noise reduction, and artifact removal to the obtained EEG signals; secondly, preprocesses the EEG signals after preprocessing The signal is characterized by extraction and separation,...

Abstract

The invention discloses a method for the electroencephalogram analysis and manipulation compensation of the mental state of a manipulator. According to the problem that in the process that the controller completes system manipulation, the control performance of a system is easily and seriously affected by the personal mental state, an electroencephalogram analysis module of the metal state of the manipulator, a manipulation quality assessment module and a manipulation precise compensation module are introduced into the control system, that is electroencephalogram signals of the manipulator are collected, and the corresponding state features are extracted based on the electroencephalogram signals, so that it is achieved that the metal state of the manipulator is precisely analyzed; the influence of the change of the metal state on the system performance is predicted by using the manipulation quality assessment module, and on this basis, control parameters of the control system are dynamically controlled according to assessment results, consequently, it can be ensured that the control task is safely and reliably executed, and the working performance of the manipulator can be sufficiently improved.

Description

technical field [0001] The invention belongs to the comprehensive technical field of information technology and artificial intelligence, and relates to an electroencephalographic analysis of a manipulator's mental state and a control compensation method thereof. Background technique [0002] With the continuous development of artificial intelligence technology, the production process has gradually shown a trend of getting rid of the dependence on human operators, and the production efficiency and safety have been greatly improved. However, from the perspective of technical feasibility, economy and safety, humans have realized that the realization of complete automation with the goal of completely replacing human operators is becoming more and more difficult, and human operators will continue to exist in various fields for a long time. in a control system. The human operator has higher authority and assumes heavier responsibilities in the entire control system, especially in...
