The application discloses a kind of intelligent risk early warning method and
system based on multi-
source data fusion, belong to construction
risk assessment and early warning technical field, the method is: obtaining multi-source information, obtains early warning
control variable based on multi-source information and preset quantization
processing mode;Early warning
control variable and preset grading early warning standard are used to build initial early warning cloud picture;Based on initial early warning cloud picture, two-dimensional matrix distribution and preset two-dimensional normal cloud model obtain three-dimensional early warning cloud picture;Improved prediction model is obtained by using
posterior probability support vector method to optimize and correct three-dimensional early warning cloud picture;Risk early warning result is obtained based on improved evidence fusion method and improved prediction model.The application provides a kind of intelligent risk early warning method and
system based on multi-
source data fusion, realizes to fuse multi-
source data as the basis to combine historical data using
posterior probability support vector method and improved evidence fusion method to build corrected three-dimensional
early warning model, significantly improve the accuracy, effectiveness and applicability of risk early warning.
