A fully mechanized coal mining face simulation method and system based on digital twinning

Abstract

This invention relates to the field of electronic digital data processing and simulation technology, specifically providing a method and system for simulating a fully mechanized mining face based on digital twins. The method involves constructing a digital twin model of the fully mechanized mining face and defining twin state vectors corresponding to objects on the face; setting consistency constraints and calculating observation residuals based on these constraints; if the observation residuals exceed a residual threshold, they are identified as abnormal observations and removed; calculating the arrival delay of each data item in the data stream to be synchronized; for data items whose arrival delays exceed the delay threshold but fall within the compensation time window, compensation observations are generated through time interpolation and aggregated to form a delay compensation observation set; fusing and correcting multi-source observations pointing to the same twin state quantity in the delay compensation observation set to obtain updated values ​​of the twin state components; and performing hierarchical state updates on the digital twin model based on the updated values ​​of the twin state components, thereby improving the accuracy and consistency of the fully mechanized mining face simulation.
