A method and system for discovering abnormal operation of drainage pipe network

Abstract

The invention discloses a method and system for detecting the abnormal operation of a drainage pipe network. The method comprises the steps of making comparative analysis on data calculated accordingto the pipeline flow and flow rate simulation model and actually measured flow and flow rate data, and locating a pipe section plugged or silted in combination with the topological relation and errorrange of the pipe network; the system comprises a data acquisition unit, a data processing and analysis unit, an analysis result push unit and a pipeline drainage model or algorithm unit. According tothe method and system disclosed by the invention, through establishment of the pipeline simulation model and actual measurement of the pipeline drainage, the pipe section draining abnormally is foundthrough the comparative analysis on actual and simulated data, and scientific data support is provided for emergency disposal of waterlogging and modification of infrastructures after events.

Description

technical field [0001] The invention belongs to the technical field of water pipe network monitoring and data processing, and in particular relates to a method and a system for finding abnormal operation of a drainage pipe network. Background technique [0002] Due to the imperfection of the urban drainage system, the caliber size and the history of each pipe section are different, resulting in frequent urban waterlogging. If the existing drainage pipes are clogged, silted, and leaked again, it will be worse. Due to the lack of suitable monitoring devices At present, full-time personnel are still regularly checking or manually checking the unobstructed condition of the drainage pipes. In order to ensure the normal operation of the drainage pipe network during the flood season, it is necessary to realize online real-time detection and early warning to accurately find abnormal pipe sections such as drainage blockage, siltation, and leakage through information technology. Con...
