Location selection method for pressure monitoring point of water supply network based on fuzzy set

Abstract

The invention relates to a location selection method for a pressure monitoring point of a water supply network based on a fuzzy set. The method comprises the steps that first, N nodes are set on a water supply network model, and the membership degree of each node of the water supply of each waterworks and the membership degree of the free pressure characteristic of each node are calculated; second, a data matrix is constructed based on the domain of discourse of the fuzzy set according to the membership degree and the membership degree of the free pressure, the data is normalized, and the datais compressed within the interval [0,1]; third, a fuzzy similarity matrix is established according to the results obtained in the second step, and each element in the fuzzy similarity matrix is determined; and fourth, a direct clustering method is adopted, according to the selection principle of the pressure monitoring point of the urban water supply network, a dynamic clustering diagram relyingon the given threshold is obtained directly according to the fuzzy similarity matrix. The method is low in calculation, and the location selection method is feasible based on the evaluation method proving of the F statistics.

Description

technical field [0001] The invention belongs to the technical field of site selection for pressure monitoring points, in particular to a method for selecting sites for pressure monitoring points of a water supply pipe network based on fuzzy sets. Background technique [0002] After the urban water supply network is modeled, the hydraulic calculation and solution of the water supply network model can be performed, and the hydraulic working conditions can be analyzed using the solved results. The hydraulic condition analysis includes various analysis forms. In the urban water supply network system, the node pressure is one of the most important hydraulic characteristics in the entire pipeline network, and it is also an index that often needs to be considered in the condition analysis. The analysis basis for applications such as pipe analysis and prediction, and pipe network security status assessment. At present, most of the site selection methods for monitoring points use th...
