Description

A device for analyzing the reliability of pipelines in a city water supply network,

The device relates to the field of urban water supply and is intended, in particular, to control the operational characteristics of urban water supply networks.

Known devices for assessing the technical condition of urban water supply networks, designed to identify the most disadvantaged areas for the purpose of planning priority restoration, repair and preventive maintenance and to prevent accidents (see Materials of the International Congress "Equatek 2000, Moscow, GUL" Vodokanal of St. Petersburg) .

In addition, devices are known for assessing the reliability and availability of water supply systems based on indicators of the reliability and availability of systems (see M. Kvatnevsky, M. Roman, “Evaluation of the reliability of water supply systems, journal J Vater SIR - Aqua, vol. 46, No. 5 , pp. 181-184,1997).

Devices are also known for selecting potential objects of rehabilitation of water supply networks based on the estimation of the survival parameters of pipelines and predicting the period of their useful life (see Maug N. Et al., Entscheidiqunqshilfen fur die Rehabilitation von Wasserrjhmetzen, DVWQHinweisW 401, Bonn, 1997), as well as to determine the priority objects of pipeline rehabilitation, taking into account the actions for their operation and factors that depend on reliability (B.Breamon et. and., 1; EM L-EAU, No. 10.1992, pp.511-517, France).

The device operates as follows.

Block 1 provides information from the operational services of the city on the state of certain sections of the city water supply network. After the initial processing of the received information from block 1, the necessary information about the reliability of the pipelines goes to block 2, information about the sanitized sections goes to block 3, and all the processed information goes to block 4.

To determine the reliability indicators of specific pipelines for given diameters, pipe materials, and areas of operation of the city water supply network, a request signal is generated in block 9, which arrives at block 2. The information selected according to the indicated parameters in block 2 is sent to block 5, in which the reliability of various sections is evaluated pipelines. This information goes to block 10, in which the nature of the information on reliability is selected.

This information can be displayed in graphical form electronic tablet maps of pipeline accidents, graphs of changes in reliability indicators in the distribution of diameters, materials, ages of pipelines laid within specific areas of the water supply network

cities, or in an overview form - summary tables of an estimation and forecast of indicators of reliability and useful lives of pipelines. Information required on request is transmitted from block 10 to the printing device 16.

If it is necessary to obtain information about the functioning of certain sections of pipelines by block 11, a request is generated, the signal from which goes to the input of block 3, from which the selected information goes to the input of block 6. All or part of the control information from block 6 is sent either to block 12, or fifteen.

In block 12 there is a selection of information about sanitized sections of pipelines, which were accidents after their rehabilitation, which then goes to the printing device 16.

In block 7, from block 3 and block 2, information is sent about the accident rate of pipelines, their passport data and about sections of pipelines sanitized by different criteria (pipe material, their age, nature of damage, etc.). The selected information is fed to the input of block 15, where it is ranked. The pipeline reliability information necessary for ranking is generated by block 14, the signal from which is fed to the input of block 3, and the information selected by this block is then fed to the input of block 7, in which potential objects for rehabilitation are selected according to the given parameters. Information from block 7 enters the input of block 15, where the ranking of selected priority objects takes place according to the criteria of reliability, location, age and the role of the site in the network. Ranked information from block 15 (in the form of lists and passports of potential rehabilitation facilities, etc.) is transmitted to the printing device 16.

To select priority rehabilitation objects, information from block 15 enters block 13, where the pipelines are ranked by selecting from potential rehabilitation objects - priority (priority) based on assessing the impact on the reliability and technical condition of the pipeline of a significant number of destabilizing factors and circumstances assessed by the point system distribution according to ranks of the level of their significance and lists and passports of priority rehabilitation objects are formed, which are also transmitted to the printing device about 16

To obtain inventory data on individual sections of pipelines, parameters are entered into block 17 for which it is necessary to obtain relevant information. The signal from block 17 enters the input of block 4, where the necessary information is selected, which is then transmitted to block 8, in which the selected information is generated according to a separate or several parameters.

This information is fed to the input of block 18, where it is ranked according to specified criteria (pipe material, by age, by pipe diameter, wall thickness, etc.). The necessary information is supplied to the printing device 16.
