Problems solved by technology

Therefore, the monitoring system that adopts the assumption that the probability of pollution events at all nodes is equal has the problem of low monitoring efficiency (such as low monitoring probability and long monitoring time) in practical applications, especially in solving water pollution monitoring of large and complex water supply networks. This defect will be more obvious on the problem

Description

technical field [0001] The invention relates to an engineering optimization method for improving the water quality pollution monitoring efficiency of a water supply pipe network. Background technique [0002] The urban water supply network is the main source of drinking water for residents, therefore, the safety of the water supply network is closely related to human health. However, in recent years, with the rapid development of the economy, sudden drinking water safety accidents have occurred frequently, seriously endangering urban production and life. Therefore, in the face of sudden accidents, how to detect them in time and minimize their impact range, so as to ensure the safety of drinking water, has become the focus of social attention and has become a research hotspot in the field of water supply. [0003] In the face of sudden pollution accidents in the pipeline network, it is often used to arrange monitoring points in the pipeline network to respond quickly to the ...
