Document Type and Number:
WIPO Patent Application WO/2023/284060
Kind Code:
A1
Abstract:
A geographic three-dimensional information-based method for analyzing the uncertainty of the flow rate of a sewage pipe network, comprising: first, according to water consumption data of a matching water supply pipe network, determining a water consumption variation random distribution property and establishing a sample pool; on the basis of a close physical relationship between the power supply pipe network and the sewage pipe network, according to a determined water consumption variation coefficient sample pool, respectively determining, in a random sampling manner, variation coefficients of flow rates of inspection well nodes of the sewage pipe network that are affected by a random factor and a system factor; and comprehensively considering the two factors to determine a normal fluctuation allowable range of the flow rate of each inspection wall node, such that analysis of the uncertainty of the flow rate of the sewage pipe network is achieved. In this way, the possibility of false alarm for disease diagnosis of a sewage pipe network is reduced, and the present invention is an important technical support for management of a sewage pipe network system.
