During the operation of amusement facilities,it is difficult to accurately capture small deformations in the framework structure,resulting in excessive strain values in the framework structure.Therefore,based on digital speckle technology,this article conducts research on online monitoring methods for load strain of amusement facility frame structures.Digital speckle technology equipment is used to accurately capture small deformations of amusement facility frame structures,and speckle image processing systems are used to collect real-time strain data under different loads.In depth analysis is carried out to extract characteristic maps of structural load strain,clearly display strain distribution,and based on these characteristic data,a load strain monitoring model is established using Kalman filtering algorithm to achieve online monitoring of load strain of amusement facility frame structures.Experimental results have shown that this method exhibits smaller strain values and a gentle growth trend under the same load,which can more accurately reflect the relationship between structure and load,and has higher measurement accuracy and performance.
