Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0038] attached figure 1 , is a schematic flow chart of an embodiment of the method for analyzing water components in independent metering districts (DMA) in the urban water supply system provided by the present invention.

[0039] Refer to attached figure 1 , the DMA water component analysis method in the described urban water supply system, comprising:

[0040] Step 01: Select a DMA in the urban water supply network system as an application demonstration area. The number of users in the independent metering area selected in this embodiment is about 1,000.

[0041] When selecting an independent metering zone, preferably, in the selected independent metering zone, the number of users is preferably more than 700, otherwi...

Abstract

The invention discloses an analysis method for independently measuring the water component of a partition in a city water supply system, which comprises the following steps: an integral analysis modelfor the water component of the water supply system; Aiming at the water component analysis model of the water supply system, a method for estimating unknown parameters (k, N, A0) according to the historical operation data of a certain period of the water supply system is proposed. Updating The parameters of the model periodically so that the water component analysis model of the water supply system is put forward and more accurate results are obtained. When the real physical leakage water is obviously increased in the results of water component analysis, issuing an alarm to remind the water supply company to carry out leakage detection, so as to reduce the loss of water resources in time.

Description

technical field [0001] The invention relates to the technical field of water balance and leakage detection of a water supply pipe network, in particular to a method for analyzing water components in an independent metering area (DMA) in an urban water supply system. Background technique [0002] Leakage of water supply pipe network is a very serious problem in our country. According to literature reports, in my country, the average leakage rate of urban water supply pipe network (the amount of water leaked from the water supply pipe network divided by the total amount of water supply) exceeds 15%. The economic loss was as high as 33.6 billion yuan. Therefore, in order to save water resources and achieve sustainable development, it is necessary to control the leakage of the water supply network and reduce the leakage rate of the water supply network. In the leakage management process of the water supply network, the first step is generally to analyze the water components of t...
