Problems solved by technology

At present, my country's urban waterlogging monitoring data often have problems such as inaccurate and insufficient records. Many data fluctuate greatly and do not have typical distribution rules. At the same time, urban waterlogging is affected by many factors, and there are uncertain and complex relationships between factors. It is a typical gray system, so it is necessary to introduce gray correlation theory and TOPSIS theory into the optimal layout of urban waterlogging monitoring points, so as to provide a scientific and effective new idea for the optimal layout of urban waterlogging monitoring points

Embodiment

[0064] 1. Instance data of waterlogging points

[0065] According to the waterlogging data of a river basin in Guangzhou in July 2013 provided by Guangzhou Drainage Center, Yuexiu District Municipal and Water Conservancy Maintenance and Management Institute, and Guangzhou Municipal Engineering Research Institute, the example data of waterlogging points are obtained, as shown in Table 1. In addition, the five-year waterlogging frequency of each waterlogging point is obtained by adding up the waterlogging times from 2010 to 2014.

[0067]

[0068]

[0069] In this paper, the waterlogging points are comprehensively sorted according to the factors affecting the waterlogging points. Urban waterlogging monitoring points should be set up in places with large water depth, wide impact range, long impact time, and frequent waterlogging within 5 years. Due to financial constraints, 10 key flooded area...

Abstract

The invention discloses an optimal layout method of urban waterlogging monitoring points. The method comprises the following steps: acquiring urban waterlogging points, and constructing a decision matrix for the urban waterlogging points; performing dimensionless processing on a magnitude of the decision matrix; determining a solution result of the dimensionless processing, and determining ideal solutions and negative ideal solutions; further determining the Euclidean distance of the ideal solutions, the Euclidean distance of the negative ideal solutions, the grey relational degree between the ideal solutions and the grey relational degree between the negative ideal solutions, and then calculating multidimensional synthetic applicabilities; sorting the multidimensional synthetic applicabilities of each urban waterlogging point by size, and the urban waterlogging point with the maximum multidimensional synthetic applicability is an optimal urban waterlogging monitoring point. The method of the invention can meet the actual requirement of urban waterlogging monitoring, provide basic data for a waterlogging monitoring system of an urban drainage network, is conducive to play the effective performance, and can quickly and accurately handle the waterlogging problem.

Description

technical field [0001] The invention relates to the technical field of optimal layout of urban waterlogging monitoring points, in particular to an optimal layout method applied to urban waterlogging monitoring points based on a gray correlation degree analysis method and a TOPSIS analysis method. Background technique [0002] In recent years, urban waterlogging disasters have been intensified, and waterlogging every time it rains has become a problem that many cities have to face. In view of the outstanding problems in urban waterlogging management at present, it is an inevitable requirement for urban waterlogging prevention and management to use computer technology to realize urban waterlogging prevention and improve the effectiveness and timeliness of urban waterlogging management. [0003] Reasonable layout of urban waterlogging monitoring points is the prerequisite for the smooth development of urban waterlogging monitoring work. The reasonable layout of urban waterlogg...
