Embodiment

[0030] Example: such as figure 1 As shown, a system using the wireless dry electrode EEG acquisition and action recognition method as described above is composed of an EEG signal acquisition circuit, a motion processing component, a CPU, and a Bluetooth module. The CPU is respectively connected with the EEG signal acquisition circuit, the motion processing component, and the Bluetooth module. Described electroencephalogram signal acquisition circuit comprises dry electrode, electroencephalogram sensor chip; As figure 2 As shown, the dry electrode obtains the analog electrical signal of the brain through contact with the forehead of the human body, and transmits this signal to the brain wave sensor chip through the shielded wire. format transfers data to the CPU. This system has a CPU system composed of STM32L052 chips, which is mainly responsible for data acquisition, data processing, and data transmission functions. The motion processing component is MPU6050 with DMP; the...

Abstract

The invention relates to a wireless dry electrode EEG collection and action recognition method and system. The function complete implementation of the system is based on correct data acquisition and interpretation. Two main data need to be acquired, the data include EEG data collected by an EEG signal collecting circuit and head posture data acquired by an action processing assembly, the CPU processes and recognizes the two sorts of data, and the result is in a specific frame format and is sent to a corresponding application host through Bluetooth. The wireless dry electrode EEG collection and action recognition method and system have the advantages that (1) head rotating control is added, head movements are collected through a movement reorganization module, control dimensionality is increased, and the problem that single electrode EEG control dimensionality is single is solved; (2) the attention of users can be well monitored, the movements can be recognized, and human brain information reorganization dimensionality is increased.

Description

technical field [0001] The invention relates to the field of EEG acquisition and motion recognition, in particular to a method and system for EEG acquisition and motion recognition with wireless dry electrodes. Background technique [0002] With the development of society and science and technology, some wearable devices based on EEG awareness have also entered the consumer field, while the existing consumer-grade dry electrode EEG acquisition equipment is mainly for the function of measuring attention and relaxation. There is only one-dimensional linear data, the control function is single, and the use feeling and effect brought to people are single. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the present invention aims to provide a method for wireless dry electrode EEG collection and action recognition. This method completes action recognition by collecting brain wave data and head posture data, so that it can monitor The us...
