Disease diagnosis method for water supply network in three stages of inspection, leakage detection and transformation

Abstract

The invention relates to a three-stage disease diagnosis method for inspection, leakage detection and transformation of a water supply network. The method comprises a health diagnosis step, a safety evaluation step and an accident prediction step. The health diagnosis step comprises the following steps: determining a high-risk pipe section of the water supply network by adopting an index scoring method according to basic attribute data and historical accident data of the water supply network; the safety evaluation step comprises the steps of establishing a mechanical model of the water supply network under different loads according to basic attribute data and real-time monitoring data of the water supply network, determining static parameters and dynamic parameters in the model, judging whether each pipeline reaches the ultimate bearing capacity or not, and generating an early warning signal if the pipeline reaches the ultimate bearing capacity; the accident prediction step comprises the steps of establishing a prediction model according to the basic attribute data and the historical accident data of each pipeline, and predicting the accident rate of each pipeline in different years in the future. Compared with the prior art, the disease diagnosis process is more comprehensive and complete, and the disease diagnosis result is more accurate, reliable and practical.

Description

technical field [0001] The invention relates to the fields of municipal engineering and water supply and drainage, in particular to a three-stage disease diagnosis method of water supply pipe network inspection, leak detection and reconstruction. Background technique [0002] In recent years, with the continuous acceleration of my country's urbanization process, the construction of municipal water supply pipe networks has developed rapidly. The municipal water supply network is one of the "lifeline" systems that a city relies on for its survival and development, and is an extremely important part of the urban infrastructure system. How to implement effective inspection, leak detection and transformation of the water supply network, respond to emergencies in a timely manner, and ensure the normal operation and maintenance of the water supply network is an important part of ensuring the normal operation of the city. However, due to rough operation management capabilities and ...
