Upper and lower bound estimation interval early warning method based on quay crane health monitoring data

The invention discloses an upper and lower bound estimation interval early warning method based on quay crane health monitoring data, and relates to the technical field of quay crane structure health monitoring early warning, the method comprises the following steps: installing an acceleration sensor on a quay crane crossbeam, carrying out structure monitoring, and obtaining monitoring data; extracting time domain features of the health monitoring data, constructing a time domain feature interval early warning model based on an upper and lower bound estimation method, and obtaining an initial dynamic threshold value; optimizing interval early warning model parameters to obtain an optimal early warning interval; and real-time dynamic early warning is realized according to the trend change of the time domain characteristics of the real-time monitoring data in the optimal early warning interval. According to the method, the abnormal symptoms of the quay crane structure can be captured in time, real-time monitori
