A brain wave monitoring system includes an electronic device and at least one electroencephalograph connected to the electronic device, each electroencephalograph includes 8 channels respectively connected to a corresponding electrode for receiving a brain wave signal. The electronic device scans a number of the at least one electroencephalograph and sequentially displays multiple channels of the at least one electroencephalograph according to an identifier of each of the at least one electroencephalograph. The brain wave monitoring system can automatically detect the number of electroencephalographs connected to the electronic device, and display the brain wave signals of all channels of all electroencephalographs according to the number of electroencephalographs and 8 channels of each electroencephalograph. The brain wave monitoring system can also prompt a guide message according to a channel impedance value and a signal quality index to assist a user improving a quality of the brain wave.
