The present invention discloses a method and
system for optimizing a
tunnel ventilation scheme, the method comprising: acquiring real-time
environmental data and fan operating parameter data in a tunnel, classifying them, and obtaining discrimination data and initial data; comparing the discrimination data with preset tunnel specifications and standards; if the limit is exceeded, obtaining the calculated values of environmental indicators at preset monitoring points in the tunnel through
computer simulation tests based on the initial data, and performing
error analysis; if the
error analysis result meets the preset threshold requirements, formulating several initial fan parameter schemes, continuing to perform
computer simulation tests, and obtaining N groups of initial fan parameters and N groups of calculated values of environmental indicators at preset monitoring points; obtaining a relationship matrix between N groups of initial fan parameters and N groups of calculated values of environmental indicators at preset monitoring points, solving it, and obtaining the optimization result of the
tunnel ventilation scheme; the present invention avoids the subjective influence of human factors on the ventilation scheme, so as to adapt to different emergencies and ensure a safe tunnel operation environment.
