Electroencephalogram, myoelectricity and inertial information synchronous acquisition device

Abstract

Provided is anelectroencephalogram, myoelectricity and inertial information synchronous acquisition device. The device comprises a multi-information synchronous acquisition sensor, an embedded micro-processing system, a wireless transmission communication interface, a data receiving platform and a power module. The multi-information synchronous acquisition sensor acquires a synchronous electroencephalogram signal, a myoelectricity signal andinertial information in real time, the signalsare sent to the embedded micro-processing system through signal conditioning such as preamplification, activefiltering,post-amplification and the like, the micro-processing system conducts A/D converting and optimizing treatment on the electroencephalogram signal, the myoelectricity signaland the inertial information, and the signalsare wirelessly transmitted to the data receiving platform through the wireless transmission communication interface. The device has the advantages of multi-signal acquisition, wireless transmission, stable communication, strong expandability, portability, easy operation and the like, can be used for real-time synchronous acquisition of the electroencephalogram signal, the myoelectricity signal and the inertial information in the movement, meets the data receiving and processing requirementsof data application platforms such as PC, mobile phone and the like, and provides great convenience for human body motion posture analyses, function evaluation, brain-computer interface researches and application fields.

Description

technical field [0001] The invention relates to the technical field of multi-physiological signal acquisition, in particular to a multi-information synchronous acquisition device capable of real-time synchronous acquisition of electroencephalogram signals, human body surface electromyography signals and motion inertial information. Background technique [0002] When a person is in a quiet state or is stimulated by external sound or light, the cerebral cortex will produce continuous and rhythmic potential changes. By placing electrodes on the cerebral cortex or scalp, the waveform of potential changes over time can be collected, and the It is extracted, amplified, and recorded to obtain electroencephalogram (EEG). EEG is a comprehensive reflection of the human body on the activities of nerve cells in the body (such as ion exchange, metabolism, etc.), which contains various forms of human thinking state information and a large amount of physiological information, and is widely...

AI Technical Summary

Problems solved by technology

[0005] Traditional physiological electrical signal acquisition equipment can only collect single-mode physiological signals such as EEG, EMG, or ECG. However, the human body is a whole with a strong cyclic unity, and it is impossible to extract only a single signal. There are many disadvantages such as comprehensive collection, incapable of comprehensive analysis, incapable of comprehensive diagnosis and evaluation, incapable of comprehensive application, etc., which can no longer meet the current application needs in many fields such as medicine, sports, entertainment, etc.
