The invention discloses a marine engine room automatic intelligent alarm analysis system and method based on digital twinning, and relates to the field of marine engine room automation. A twinborn digital model of a ship machinery entity is built, a data prediction model is built through obtained operation state parameter sampling values, operation state parameter prediction values are obtained through the data prediction model, and time sequence data sequences L and L'are built through the operation state parameter sampling values and the operation state parameter prediction values respectively; a difference value data sequence # imgabs0 # is obtained, the number of wavelet decomposition layers is set to be N, wavelet transformation processing is carried out on the difference value data sequence # imgabs1 #, a Markov chain model of the operation state parameter sampling value state is constructed, a state transition matrix is obtained, an observation probability matrix of the operation state parameter sampling value is constructed, and the observation probability matrix of the operation state parameter sampling value is obtained; and defining state values when st1 = 1 and st0 of the sampling value states of the operation state parameters, constructing a judgment function by using the state values, and judging the abnormal condition of the sampling value of the operation state parameters at the t moment according to a calculation result of the judgment function.
