The invention provides a recognition method, a recognition system and a detection system for electroencephalogram signal interference. The recognition comprises the following steps: receiving a to-be-analyzed electroencephalogram signal; performing feature analysis on the electroencephalogram signal to obtain a first feature analysis result corresponding to a first feature of the electroencephalogram signal and a second feature analysis result corresponding to a second feature of the electroencephalogram signal; comparing the first feature analysis result with a first reference analysis result to obtain a first recognition result corresponding to a first feature of the electroencephalogram signal, and comparing the second feature analysis result with a second reference analysis result to obtain a second recognition result corresponding to a second feature of the electroencephalogram signal. According to the first recognition result and the second recognition result, interference recognition is conducted on the electroencephalogram signals, and a third recognition result corresponding to the current electroencephalogram signals to be analyzed is obtained. By means of the method, whether interference exists in the electroencephalogram signals or not can be judged more accurately.
