description The invention relates to a portable brain blood flow signal monitoring system. The portable brain blood flow signal monitoring system comprises a controller, a dual-wavelength LED light source and a dual-path detector, wherein the dual-wavelength LED light source and the dual-path detector are electrically connected with the controller; the dual-wavelength LED light source is used for emitting a dual-wavelength light signal with stroboflash elimination to a to-be-detected part of the brain under the control of the controller; the double-path detector is used for receiving the dual-wavelength optical signal reflected from the to-be-detected part of the brain and sequentially performing electric signal conversion processing, filtering processing, signal following and amplifying processing and AD conversion processing to obtain a dual-wavelength original PPG signal; and the controller is used for performing noise reduction filtering processing and characteristic parameter extraction processing on the dual-wavele
