The invention discloses a big data-based attention training system. The big data-based attention training system comprises: a main controller comprising a main processor; a chair on which baffles arearranged; a sub display screen; a method selection module, wherein information of different attention training methods and factors associated with the information of the attention training methods arestored in the method selection module; a virtual scene module for storing noise in different scenes; a data acquisition platform; a data statistical module; an expert analysis module which is connected to the data statistical module and the main processor, and is configured to analyze the data of the data acquisition platform to formulate an attention training scheme for the data and transmit theattention training scheme to the main processor; and the main processor selects noise in different scenes according to the information of the selected attention training method for playing. Variousattention training methods are combined to be provided for a trainee, so that the trainee can self-select the method of interest, and an online expert is connected to formulate a reasonable training scheme for the low-attention trainee.
