Problems solved by technology

Among portable products, EPOC uses wet electrodes with 14 electrodes, which is not easy to operate by yourself. Although NIA uses dry electrodes, its transmission method is wired, and Mindset is a single-electrode earphone.
Therefore, in the prior art, the main disadvantages are summarized as follows: 1. The medical EEG acquisition instrument is complicated in equipment and high in cost, and a special person is

Abstract

The invention discloses a portable electroencephalogram collection system which comprises a collection electrode and a signal processing system. The signal processing system comprises a microcontroller, an input filter, a static protection unit, an instrument amplifier, an analog-digital converter, a storage module, a radio frequency transceiver, a power source management system and a display operation module, the power source management system comprises a power source module, a program storage unit and an induction eddy current charging circuit, and a display input module comprises a state display lamp and a button configuration unit. Electrodes are placed at foreheads of Fp1, FpZ and Fp2, and interference caused by hair is avoided, so that medical pasted wet electrodes are used, and interference of electrode contact impedance is avoided. A low-power-consumption device is adopted mainly, and the power source management system is arranged, so that state of a power source can be monitored, noise can be removed effectively, and elimination of electro-oculogram noise is based on an improved algorithm of discrete wavelet transformation and self-adaptive noise offset.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a portable electroencephalogram acquisition system. Background technique [0002] Human brain activity has been studied for a long time. In 1924, German psychiatrist H. Berger first discovered and recorded regular electrical activity on the scalp of epileptic patients, and in 1929, he made a holistic description report on human electroencephalogram (EEG), revealing that Opened the prelude to the study of human brain electrical activity; then in 1935, Gibbs et al. introduced EEG research into the diagnosis of epilepsy; in 1937, Hoagland, who was committed to biological research, analyzed human EEG signals under different metabolic intensities In 1972, A.Beck published relevant academic papers on brain wave research, which brought the research on brain electrical activity to a climax. [0003] EEG has become a useful means of diagnosing brain-related diseases, such as...
