if the m different uploading marking codes are acquired, clathrating the received m blueprint system uploading subfiles into a cloud blueprint system file; step S22 is performed;
s22, acquiring the arrangement identification codes in m blueprint system uploading sub-file packages and blueprint system uploading sub-files, and judging whether the identification codes are consistent with the operation values of the blueprint system uploading sub-files corresponding to the identification codes or not:
if all the identification codes are consistent with the operation values of the blue-print system uploading subfiles corresponding to the identification codes, executing step S23;
if the operation values of the blueprint system uploading sub-files corresponding to the identification codes are inconsistent, the file verification is not passed, and the cloud server requests the request end to upload the blueprint system uploading sub-file package corresponding to the identification codes again;
s23, after the arrangement codes are arranged according to the order from small to large, the blueprint system uploading sub-files are arranged according to the arrangement order of the corresponding arrangement codes, and the cloud blueprint system files are synthesized.
