Abstract

The portable radio multichannel electrocerebral data acquiring instrument consists of one electrocerebral data acquiring device and one electrocerebral data receiving device communicating mutually in radio communication mode. The electrocerebral data acquiring device includes multichannel electrocerebral electrodes, a pre-amplifier circuit, a post-amplifier circuit, a filter circuit, an A/D converter circuit, a monolithic computer and a radio communication sending circuit; and the electrocerebral data receiving device includes a radio communication receiver circuit, a monolithic computer based on USB interface and a computer. The electrocerebral signal is first amplified, filtered, A/D converted and sent, and then received and transmitted to the computer for real-time analysis and treatment. The present invention has no electric connection between the testee and the computer, and is flexible, safe and reliable.

Description

technical field [0001] The invention relates to a portable wireless communication multi-channel EEG data acquisition instrument, which is a device for collecting and processing spontaneous EEG signals and induced EEG signals, and belongs to the technical fields of electronic information technology and biomedical engineering. Background technique [0002] The brain is the most important active organ of the human body. To uncover the mysteries of the brain, on the one hand, it is the need for people to understand the laws of their own intellectual activities, and on the other hand, it is also the need for people to consciously promote, regulate and control their own brain activities. Various signals such as electrical, magnetic, metabolic, chemical, thermal, and mechanical responses that accompany brain activity can be collected and identified, and can be used to analyze the activity of the brain. The advantages of high resolution, portable equipment, and low price have become...
