Human brain electrical information collection system based on single chip microcomputer

Abstract

The invention relates to a human brain electrical information collection system based on a single chip microcomputer. The human brain electrical information collection system comprises a brain electrical signal acquisition device and an experimental recording table. The brain electrical signal acquisition device includes a brain electrical information acquisition module, a brain electrical signal judgment module and a first wireless communication module. The experimental recording table includes a table base, a control box is arranged on the table base, and support legs are arranged at the bottom of the table base; a fixing seat is arranged inside the table base, the inner ring of the fixing seat is provided with an annular gear, and a wheel gear is arranged inside the fixing seat; the center of the fixing seat is provided with a rotation shaft, the rotation shaft is connected with a rotation shaft of the wheel gear through a connection rod, and the edge of the wheel gear is provided with a mounting seat; a vertical toggle shaft is installed on the mounting seat, the top of the toggle shaft is provided with a bearing, and the bearing is installed at the bottom of a work table plate; a guide rail is installed on the fixing seat, the bottom of the working table plate is provided with a sliding seat, and a stepping motor is arranged at the bottom of the inside of the table seat. According to the human brain electrical information collection system, the data is transmitted by wireless signal, after the people to be tested go to sleep, the system is allowed to open the experimental recording table, and recording is thus convenient to conduct; after the people to be tested wake up, the system is allowed to put the experimental recording table away, recording is thus stopped, and therefore accuracy of recording time node can be effectively improved.

Description

technical field [0001] The invention belongs to the field of EEG information, in particular to a human EEG information collection system based on a single-chip microcomputer. Background technique [0002] During the sleep study, the test subjects went to sleep to collect experimental data. However, it is difficult to confirm the starting point of sleep of the subjects, which leads to inaccurate sleep measurement data. The testee and the experimenter are in the same place, which creates pressure on the testee and easily affects the experimental measurement results. For the sleep of patients with insomnia, the experimenter needs to wait for their sleep for a long time, and may miss the start time of sleep, and needs to repeat the experiment many times, which increases the workload of the experimenter and distracts the energy of the experimenter. Contents of the invention [0003] The invention provides a single-chip microcomputer-based human body EEG information collection...
