The invention discloses a drainage
pipe network assessment method and
system based on multi-
factor analysis, and relates to the field of drainage
pipe network management, and the method comprises a collection module which is used for collecting the historical operation data of a drainage
pipe network and the real-time
monitoring data of a to-be-assessed time period, and forming an
original data set with a space-time
label; the
processing module is used for carrying out preprocessing of
time alignment, space calibration and anomaly correction on the
original data set, and generating a time-space correlation standardized
data set comprising historical sample data and to-be-evaluated sample data; historical operation and real-time
monitoring data of the drainage pipe network can be accurately integrated, deviation is corrected through
data calibration, features are extracted by integrating structure, hydraulic power and environmental factors, evaluation weights are dynamically adjusted according to pipe network building, stable operation and aging stages, a current health level, a bearing threshold value and a
future risk trend are accurately output, early warning is carried out when the value exceeds a limit, and the safety of the drainage pipe network is guaranteed. Hidden dangers can be checked in time, and stable operation of a pipe network is guaranteed.
