Problems solved by technology
The signal passes through the filter of the acquisition system to limit the background noise, but in this process, the filter also covers up or changes certain EEG signals; secondly, due to a certain signal loss on the impedance line, the long conductive line leads to detection Signal accuracy is very poor
[0007] Due to the great interference of the measurement of weak electrical signals, these problems have seriously affected the development of biosensing

The invention discloses an active noise control digital electrode collecting system and a collecting method thereof. The active noise control digital electrode collecting system comprises a controller and at least one active noise control digital electrode; the controller is connected with the least one active noise control digital electrode and connected with one, two or more active noise control digital electrodes through time sharing option; the active noise control digital electrodes are used for collecting electric signals of human bodies and process and convert the electric signals into digital signals, and the digital signals are output to the controller; physiological electric wave signals are connected in the position closest to the collecting point and converted through a digitization method, so that noise is lowered, the signal-to-noise ratio is decreased, a high-accuracy detection signal is obtained, and the signal measuring accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of digital electrodes for bioelectrical signal acquisition, in particular to a digital electrode acquisition system and acquisition method based on active noise reduction for EEG, ECG and EMG. Background technique [0002] The bioelectrical signal acquisition device is in contact with human skin, and the electrical signal measured on the skin surface is usually used to detect various physiological signs, for health management, etc. It can detect bioelectricity at the level of millivolts or even microvolts, such as measuring electroencephalogram (EEG), electrocardiogram (ECG) and electromyography (EMG). [0003] The electrical signal produced by the beating heart is called ECG and is used to assess the state of the heart and can detect some types of heart disease. Electrical signals generated by muscle movement, called myoelectricity, are used to detect neuromuscular activity, and their evaluation can detect...
