The application provides a
water supply pipe network
corrosion pipe section identification and diagnosis method based on
water quality inversion, the method collects
water quality data and
pipe section attribute information in a
water supply pipe network area, determines the topological
water flow direction based on the
residual chlorine decay characteristics, determines the appropriate diagnosis node and target independent pipe section, monitors the
water quality parameter change characteristics in the pipe section, combines the water quality change amount and the quantitative evaluation model of the pipe section
corrosion degree, realizes the target positioning of the
corrosion pipe section and the rapid inversion diagnosis of the corrosion state, the input layer of the model is the water quality change characteristics and pipe section information between the pipe network diagnosis nodes, the operation layer adopts an
algorithm based on the water quality decay characteristics and the corrosion state mapping relationship, and the output layer is the pipe section corrosion state
score, when the diagnosis result is lower than the preset safety threshold, the warning information and the maintenance suggestion are generated, the application can realize the diagnosis effect with the determination coefficient exceeding 0.95, and effectively improves the safety and reliability of the operation management of the
water supply pipe network.
