The invention discloses a major
hazard source risk dynamic calculation
system based on AI
large model enabling, and relates to the technical field of risk calculation, and the
system comprises a multi-
modal data collection and preprocessing module which is used for achieving the synchronous collection of
original data through the
butt joint of an industrial protocol with a sensor; the heterogeneous
data space-time fusion engine module is used for constructing a space-time diagram model and analyzing a
nonlinear coupling relationship of multi-
source data; the online
incremental learning and model
fine tuning module is used for triggering dynamic parameter adjustment based on the real-
time data flow; a risk conduction probability calculation module; a multi-
modal knowledge self-evolution module; and a self-adaptive threshold management and alarm module. According to the method, sliding window dynamic
confidence interval calculation is combined with a time-varying confidence coefficient adjustment mechanism, self-adaptive fitting of a threshold value to real environment disturbance is achieved by embedding a periodic correction term, the bidirectional contradiction between detection sensitivity and
false alarm suppression is effectively cracked, and a complete technical
closed loop from dynamic sensing and cross-domain
verification to rapid linkage is formed.
