Problems solved by technology

In traditional sensitivity analysis, constructing an objective function by finding the detection point with the highest sensitivity for each abnormal node cannot ensure that the average sensitivity is large enough; and using the average sensitivity as the objective function cannot guarantee that the node with the highest sensitivity can be optimized
And the sensitivity standard deviation method will make the

Embodiment Construction

[0050] In order to make the technical innovations realized by the present invention easy to understand, below in conjunction with the accompanying drawings and examples, the implementation of the present invention is further described in detail, and the specific steps are as follows:

[0051] 1. Obtain fuzzy similarity matrix

[0052] (1) Sensitivity coefficient matrix

[0053]There are 5377 nodes in the DMA in S City (not counting the water source). In order to select a better working condition, the model data of the DMA at 12:00 noon, the maximum working time, is used as the test data. An example of water demand at a node is shown in Table 1:

[0054] Table 1 Node traffic

[0055]

[0056] Among them, the node numbers are sorted according to the index. For some nodes, the water demand is 0, such as index 5375, so that the water demand is a small value, 0.0000001. Run the EPANET model and perform a time-delay simulation to obtain the node pressure vector R before the n...

Abstract

The invention discloses an optimized arrangement method for monitoring points of an urban water supply pipe network. The invention improves the traditional sensitivity analysis and cluster analysis methods separately and combines the two methods to obtain optimized distribution of monitoring points, so that the arrangement of the monitoring points can have the characteristics of being good in sensitivity, being relatively dispersed and facilitating the delimiting of abnormal regions for accurate detection, and meanwhile, the monitoring points are more widely and uniformly distributed as compared with those in the prior art, and are reasonably arranged at key positions, thereby facilitating model verification.

Description

technical field [0001] The invention belongs to the field of urban water supply pipe networks, in particular to a method for optimizing the layout of measuring points for urban water supply pipe network monitoring. Background technique [0002] The measuring point layout of the water supply pipe network refers to the distribution and installation of a certain number of flow and pressure sensors in the water supply pipe network to monitor the operating conditions of the pipe network and provide data support for pipe network scheduling analysis. Due to the large scale of my country's urban water supply network and complex pipelines, flow measurement and pressure measurement points are not deployed in the initial construction and expansion of the network, and there is a lack of system considerations, resulting in biased measurement, and the operation status of the water supply network cannot be comprehensively and accurately measured. Reflect, and then affect the scientific anal...
