Early warning model test method and device for supercritical unit under mechanism diagnostic analysis

The invention relates to an early warning model test method and device for a supercritical unit under mechanism diagnosis analysis. According to the specific scheme, measuring point data of a plurality of mechanism models are obtained; performing verification processing on the plurality of measuring points based on the measuring point names, the measuring point identifiers and the monitoring values of the plurality of measuring points of the mechanism model; determining respective fixed values of a plurality of operator blocks in the mechanism model in response to the fact that the plurality of measuring points pass verification; inputting the respective detection values of the plurality of measuring points into a mechanism model to obtain an early warning result output by the mechanism model based on the respective fixed values of the plurality of operator blocks and the respective detection values of the plurality of measuring points; comparing the early warning result with a real result to obtain a first c
