Physiological signal recording system and physiological signal recording instrument thereof

The invention provides a physiological signal recording system and a physiological signal recording instrument thereof, and relates to the technical field of medical electronic equipment. The physiological signal recording instrument comprises a body of wearable equipment and an electroencephalogram collecting end; the body is at least used for receiving and transmitting an electroencephalogram; the electroencephalogram collecting end is used for collecting the electroencephalogram, and sending the electroencephalogram to the body through wireless communication; the body sends the electroencephalogram to an upper computer through the wireless communication. According to the physiological signal recording system and the physiological signal recording instrument thereof, the technological problem that an existing electroencephalogram collecting device cannot collect the electroencephalogram generated in an actual life of a user, and thus a technological effect of collecting the electroencephalogram generated in
