This invention proposes an information-based
engineering supervision method and
system based on
big data. The method includes: acquiring a set of supervision
record data and
engineering stage identifier data; based on the
engineering stage identifier, generation
timestamp, and
record type of each supervision
record, combined with the boundaries, order, and allowed record types of the engineering stages, selecting records that meet the conditions of stage consistency and prior existence to form a set of
usable supervision records; merging records according to the order of engineering stages, and sorting them according to
timestamp and record identifier within each stage to construct a supervision process representation structure; based on this structure, performing coverage and order consistency checks on the set of necessary engineering stages corresponding to the target supervision conclusion, generating a determination result of the validity of the supervision conclusion; and outputting the engineering supervision handling status accordingly, controlling the progress or locking of engineering stages, and improving the
automation and
traceability of supervision.
