Real-time processing method for removing long-term trend of dynamic monitoring data of internal force of bridge structure

The invention provides a real-time processing method for eliminating a long-term trend of dynamic monitoring data of internal force of a bridge structure, and the method comprises the steps: firstly, carrying out the processing and decomposition of test data of structure response through employing wavelet analysis, and obtaining monitoring data with the elimination of a long-term change trend, and enabling the monitoring data to serve as subsequent verification data; and then, carrying out real-time processing of removing a long-term trend on the original data, considering the influence of vehicle load, sensor equipment abnormity and the like on a trend processing process in real time, removing a data long-term change trend caused by environment temperature in real time, and comparing the difference degree between the processed data and verification data to obtain a data processing result. And determining optimal parameters required to be configured during real-time processing. According to the method, real-t
