Brain fatigue monitoring device based on combination of electroencephalogram and near infrared

The invention discloses a brain fatigue monitoring device based on combination of electroencephalogram and near infrared, which comprises a head wearing part, an arc-shaped strip group is arranged at the inner top of the head wearing part, an adjusting mechanism is arranged on one side of the head wearing part, and an electroencephalogram electrode, an emitting optrode and a receiving optrode are respectively arranged on the arc-shaped strip group; a control host is arranged on the surface of the head wearing part, a control mainboard is arranged in the control host, and the control mainboard comprises an optical driving module, a power supply module, a signal processing module, a main control module and a data transmission module. The brain fatigue state recognition accuracy can be effectively improved through combination of the electroencephalogram signals and the near-infrared light density change signals, the positions of the electroencephalogram electrodes, the positions of the emitting optrode and the p
