Abstract

The invention relates to an electroencephalogram collecting and transmitting system and method. The electroencephalogram collecting and transmitting system comprises an electroencephalogram signal collecting circuit, a first optical signal circuit, a second optical signal circuit, a digital processing circuit and a collecting host machine, wherein the electroencephalogram signal collecting circuit is used for collecting multi-channel electroencephalogram signals, the first optical signal circuit is connected with the electroencephalogram signal collecting circuit and used for converting the multi-channel electroencephalogram signals into optical signals, the second optical signal circuit is coupled with the first optical signal circuit and used for receiving the optical signals and converting the received optical signals into first electrical signals, the digital processing circuit is connected with the second optical signal circuit and used for conducting digital processing on the first electrical signals to obtain second electrical signals, and the collecting host machine is connected with the digital processing circuit and used for displaying and analyzing the electroencephalogram signals. Transmission is achieved through the optical signals, so that electric isolation between the electroencephalogram signal collecting circuit and the digital processing circuit can be achieved, and the electroencephalogram collecting and transmitting system has the advantages of being resistant to interference, stable and high in transmission speed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a system and method for collecting and transmitting brain electricity.
