After the division equipment receives the 1 st section data and the characteristic codes of the 1 st section data, the characteristic extraction module is used for calculating the characteristic codes of the 1 st section data, and the calculated characteristic codes are compared with the characteristic codes of the 1 st section data pushed by the transmission module. If the 2 feature codes are completely consistent, the received 1 st segment data has no transmission error, otherwise, the 1 st segment data has transmission error and needs to be retransmitted; and after the segment 1 data received by the sub-equipment has no transmission error, starting to continuously receive the segment 2 data pushed by the main equipment. After the division equipment receives the 2 nd section data pushed by the transmission module, the static detection module is used for checking the 2 nd section data, and if the checking is unsuccessful, the check indicates that the 2 nd section data is in error transmission and needs to be retransmitted. After the operation is finished, the whole transmission module finishes the transmission operation, the 1 st section data and the 2 nd section data received by the sub-equipment have no transmission errors, and the sub-equipment stores the received data in the sub-equipment.
