The application provides a kind of early warning method for monitoring abnormal state of gas
pipe network, it is related to
gas monitoring and early warning field, using the
monitoring system including data preprocessing module, space-time feature module, ST-CGN
network module, edge intelligent optimization module and result
processing module;Among them, the ST-CGN
network module outputs the multi-working condition
probability vector corresponding to the sliding window slice through the input of three-dimensional feature
tensor, at the same time, the space-time
convolution layer in the ST-CGN
network module simultaneously models the local dependence of space neighborhood relationship and time sliding window, maintains time
causality;The edge intelligent optimization module realizes the edge optimization of ST-CGN network module through MAML fast
adaptation, knowledge
distillation, model
pruning and quantization.This method effectively solves the problems existing in the existing gas
pipe network monitoring method, such as data missing, easy to be disturbed by
noise, insufficient multi-point
coupling identification, poor cross-scene generalization ability, monitoring alarm with lagging nature and so on.
