Method, device and equipment for automatically synchronizing data among heterogeneous units and medium

The invention discloses a method, a device and equipment for automatically synchronizing data among heterogeneous units and a medium. The method comprises the following steps: after a data synchronization triggering instruction is received, determining an original data position and an original data size of to-be-synchronized data in an original queue according to a first initial address, a first writing position and a first reading position corresponding to the original queue; according to a second initial address, a second writing position and a second reading position corresponding to the mirror image queue, determining a data accommodating position capable of accommodating data and an accommodating data size in the mirror image queue; and determining the target length of the target synchronization data in the original queue according to the data relationship between the size of the original data and the size of the accommodated data, and synchronizing the target synchronization data with the target length
