Aiming at the problems of coordinate drift of twin positioning and unimpeded communication between the twin layer and the physical layer,an improved Fang-Taylor positioning algorithm is proposed for multi-object real-time positioning.The heteroge⁃neous data hybrid fusion method and the industrial Internet identification analysis system are used to open up the data path between the twin layer and the physical layer.The verification results show that the improved Fang-Taylor algorithm can effectively take into ac⁃count the computational efficiency and positioning accuracy of multi-object positioning in digital twin applications.The hybrid data fu⁃sion method and the identification analysis system can effectively realize the data exchange and two-way operation between the physi⁃cal layer and the twin layer.
