Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
A DMA (discrete Metering Area) is an Area that can divide a municipal water supply network into a number of different independent areas depending on the terrain, the roads or the number of users, etc. The existing partition management method based on DMA can only detect the condition that which partitions have leakage, but can not automatically detect which user in the leakage partitions has leakage. For example, a leakage management method disclosed in patent application No. 202011259055.6 and a method and system for acquiring water supply data based on partition metering disclosed in patent application No. 202010556656.7 both determine a partition where a leakage exists based on total water usage in the partition, a minimum partition night flow rate, and/or a mean partition night pressure, but cannot further locate a user where a leakage exists in the partition.
In the prior art, if the leakage position in the partition is to be further determined, each user in the partition needs to be checked one by one. For example, patent document No. 202011423982.7 discloses a user remote meter reading data intelligent processing method based on cloud computing, which directly compares the water consumption corresponding to the latest historical remote meter reading record of each user with the average water consumption corresponding to the standard quantity of many months, so as to determine whether the user has leakage or not, and a great amount of time is wasted in a one-by-one checking mode. The patent document with the application number of '201911313009.7' discloses a method and a system for monitoring leakage and positioning leakage of a water supply pipeline, wherein the whole water supply pipeline area is subjected to closed zoning, the leakage pipeline section is determined by using a noise recorder installed in each zone after the leakage zone is determined, and then the noise data of the leakage pipeline section is collected by the noise recorder based on a manual detection mode to realize the positioning of a leakage point, so that a systematic monitoring means for positioning a suspected leakage pipeline section from the monitoring of the leakage loss of the zones and then positioning a specific leakage point is realized. According to the detection method, a water closing test needs to be manually carried out to ensure the sealing performance of each subarea, the detection of specific leakage points also needs to be manually participated, and the detection speed is low. Generally, there are many users in each partition, and a large amount of time and manpower are consumed for a leakage detection method for checking users one by one, so that the detection efficiency is low.
In order to solve the technical problem, the embodiment of the application provides a water supply network leakage detection method and system based on an electromagnetic water meter. After a leakage area to be detected is detected, determining leakage buildings in the area to be detected according to the acquired total water consumption of the area to be detected and each building in the area to be detected in a water using period and the acquired total water consumption of each building in a historical month by using the subareas, the multiple buildings in the subareas and the topological relation among a plurality of users in each building; and then determining the users with leakage in the leakage building according to the water consumption of each user in a water consumption period and the water consumption of the users in the historical months. The leakage detection method can quickly and accurately determine the position of the leakage point in the region to be detected, detection personnel do not need to check each user in the region to be detected, and the leakage detection efficiency of the water supply network is improved.
The technical solution of the present application is described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
In one possible implementation manner, as shown in fig. 1, the method for detecting leakage of a water supply pipe network based on an electromagnetic water meter provided by the present application includes the following steps:
s100, when a to-be-detected area with leakage in a water supply network is detected, acquiring water consumption data through an electromagnetic water meter, wherein the water consumption data comprise first data and second data of two adjacent water using periods of the to-be-detected area in the current year, third data corresponding to the second water using period of the to-be-detected area and the two adjacent water using periods in the previous year, fourth data and fifth data of two adjacent water using periods of each user in the to-be-detected area in the current year, and sixth data corresponding to the second water using period of each user in the previous year.
It should be noted that the area to be tested is generally the smallest partition in which leakage exists in the DMA-based urban water supply network. Each subarea comprises a plurality of buildings, and each building comprises a plurality of users. Illustratively, the area to be measured may be a cell, an office area, or the like.
The water supply pipe network system based on DMA generally stores the total water consumption data of each subarea in each water using period. The DMA-based water supply pipe network system can automatically monitor the leakage condition of each subarea according to the obtained total water consumption data. For example, since the nighttime minimum flow is less affected by seasonal variations, the zones in the water supply network where and to what extent there is a leak can be determined by nighttime minimum flow analysis.
Once a subarea with leakage in the water supply network in a water using period in the year is detected, the subarea is determined as the area to be measured. Meanwhile, the water supply pipe network leakage detection method provided by the application can be triggered to be executed, the total water consumption data of the area to be detected in the water supply pipe network system in the water using period, the previous year synchronization period and the period adjacent to the water using period in the current year and the water consumption data of each user in the area to be detected are respectively read, and the leakage point of the area to be detected is automatically detected according to the read water consumption data.
In one example, the water consumption data of the area to be measured in each water using period and the water consumption data of each user in the area to be measured in each water using period can be obtained by manually reading the water consumption data displayed in the electromagnetic water meter, and each water consumption data is uploaded and stored into the water supply network system. In another example, an intelligent water meter may be installed at the water inlet and outlet of the area to be measured and the water inlet of each user, and the intelligent water meter may transmit and store the collected water consumption data of the area to be measured in each water cycle or the water consumption data of each user in each water cycle to the water supply network system. The intelligent water meter is an electromagnetic water meter which can automatically upload water consumption data to a water supply pipe network system.
Based on the water consumption data acquisition method provided in the above embodiment, when detecting that there is a region to be detected of leakage in the water supply network, the water supply network leakage detection method provided by the application is triggered and executed, and the water consumption data is read. The water consumption data comprises first data and second data of two adjacent water using periods of the area to be detected in the current year, third data corresponding to the second water using period of the two adjacent water using periods in the previous year of the area to be detected, fourth data and fifth data of two adjacent water using periods of each user in the area to be detected in the current year, and sixth data corresponding to the second water using period of the two adjacent water using periods in the previous year of each user.
S200, determining seventh data and eighth data of each building in the area to be detected in two adjacent water using periods in the current year and ninth data of the building corresponding to the second water using period in the previous year according to a preset virtual building table, fourth data, fifth data and sixth data corresponding to the area to be detected, wherein the virtual building table is used for describing the corresponding relation between the building and users in the area to be detected.
It should be noted that if the electromagnetic water meter is installed at the water inlet of each building to obtain the water consumption data of each building in each water consumption period, batch installation, maintenance and replacement are required, a large amount of manpower, material resources and financial resources are consumed, and the management cost is high. According to the leakage detection method, a physical water meter does not need to be installed in each building, and a virtual building meter is established according to the user sub-meter in each building in the subarea so as to obtain the water consumption data of each building, so that the management cost is saved.
Specifically, in one embodiment, a topological relationship among the partition summary table, the virtual building table of each building in the partition, and the household tables of the users in each building may be preset based on the corresponding relationship among the partitions, the buildings in the partitions, and the users in each building. When the leaked region to be detected is detected, determining the corresponding relation between a plurality of buildings in the region to be detected and users according to a preset virtual table in the region to be detected, and accordingly determining seventh data and eighth data of each building in the region to be detected in two adjacent water using periods in the current year and ninth data of each building corresponding to the second water using period in the previous year.
Illustratively, for each building in the area to be detected, the sum of the water consumption data of each user in the building in a water consumption period is the water consumption data of the building in the water consumption period. And aiming at each building in the area to be detected, the seventh data is the sum of the fourth data of each user in the building, the eighth data is the sum of the fifth data of each user in the building, and the ninth data is the sum of the sixth data of each user in the building.
One water use period described in the above embodiments may be one month or more. For example, assuming that the DMA-based water supply pipe network system may perform leakage detection once a month, if a leakage-existing cell (i.e. a to-be-detected area) is detected according to the acquired water consumption data of the water cycle of the 4 th month of 2021 at 5/1 th of 2021, and the cell has 3 buildings, first data of the cell in the 3 rd month of 2021 (i.e. first data of the first water cycle of the to-be-detected area in two adjacent water cycles in the present year), second data of the cell in the 4 th month of 2021 (i.e. second data of the second water cycle of the to-be-detected area in two adjacent water cycles in the present year) and third data of the 2020 th month of the to-be-detected area in the last year (i.e. third data of the to-be-detected area corresponding to the second water cycle of the two adjacent water cycles in the present year) are acquired, and fourth data of the 3 rd month of the building in the cell in the present year, The fifth data of the month 4 of 2021 and the sixth data of the month 4 of 2020, the seventh data of each building in the month 3 of 2021, the eighth data of the month 4 of 2021 and the ninth data of the month 4 of 2020.
In one embodiment, the types of leakage from the water supply network include physical leakage and apparent leakage. The physical leakage refers to the amount of water leaking out of a pipe network system due to the damage of the pipeline and the auxiliary structure thereof. The apparent leakage represents the leakage caused by illegal water use such as theft, fraud and the like or water meter data error reading. According to the acquired water consumption data, the specific user in the area to be detected can be determined to have leakage (namely a leakage point) and the type of the leakage.
And S300, determining a leaking building according to the first data, the second data, the third data, the seventh data, the eighth data and the ninth data, wherein the leaking building is a building with leakage in the second water using period in the area to be detected.
Generally, the difference between the proportion of the water consumption data of one building in a water using period in the total water consumption data of the same water using period in the area to be detected and the proportion of the water consumption data of the building in the historical water using period in the total water consumption data of the corresponding historical water using period in the area to be detected is smaller; if the difference is large, the building is indicated to have leakage.
In one embodiment, a first ratio of the seventh data to the first data, a second ratio of the eighth data to the second data, and a third ratio of the ninth data to the third data are obtained for each building in the area to be measured. And if the second ratio is greater than the first ratio and greater than the third ratio, determining that the building is a leakage building, and the leakage building has physical leakage or apparent leakage in the second water using period of two adjacent water using periods in the current year. For example, the leakage building may have physical leakage caused by the water pipe breakage of one user or a plurality of users, or apparent leakage caused by the fact that fifth data of one user or a plurality of users is larger than real water meter display data when meter reading is carried out.
In another embodiment, a first ratio of the seventh data to the first data, a second ratio of the eighth data to the second data, and a third ratio of the ninth data to the third data are obtained for each building in the area to be measured. And if the second ratio is smaller than the first ratio and smaller than the third ratio, determining that the building is a leakage building, and the leakage building has physical leakage in the second water using period of the two water using periods in the year. For example, the physical leakage may be caused by the breakage of a water supply pipeline between a total water meter of a region to be measured and a leakage building, so that the water flow of each user in the leakage building is reduced after the water pressure is reduced, and the first ratio is smaller than the second ratio and smaller than the third ratio.
Based on the above embodiment, if the second ratio is smaller than the first ratio and smaller than the third ratio, a prompt message may be sent to the water supply manager of the area to be detected, so as to prompt the manager to go to the area to be detected for further leakage detection and take some control measures to reduce leakage.
And S400, determining users with leakage in the second water using period in the leakage building according to the fourth data, the fifth data and the sixth data.
Generally, the difference between the water consumption data of each user in a water consumption period and the water consumption data of the user in a historical water consumption period is small, and if the water consumption data of the user in one month is simultaneously larger than the water consumption data of a plurality of historical months, leakage of the user is indicated.
In one embodiment, for each user in the leaking building, when the fifth data is greater than the fourth data and greater than the sixth data, it is determined that the user has a physical or apparent leak in the second of two adjacent water usage periods in the year. For example, the physical leakage caused by the broken water pipe in the home of the user may be possible, or the eighth data of the user, which is read when the meter is read, is larger than the actual display data of the water meter of the home of the user.
Based on the above embodiment, when it is detected that the user has a leakage, a prompt message indicating that the leakage exists may be sent to the user. Illustratively, the acquired fifth data of the second water using period of the two adjacent water using periods in the current year can be sent to the user in the form of a short message, a mail or the like, and the information that the water pipe is broken or the meter reading is wrong may exist in the home of the user is prompted, so that the user can perform leakage control in time.
The water supply network leakage detection method based on the electromagnetic water meters can utilize topological relations among the regional general meter, the virtual meters corresponding to a plurality of buildings in the region and the sub-meters of a plurality of users in each building, determine the leakage building in the second water using period in the region to be detected according to the acquired water using data of the region to be detected and each building in the region to be detected in the two adjacent water using periods in the current year and the water using data of the second water using period in the two adjacent water using periods in the previous year, analyze and compare the water using amount of each user in the leakage building in the second water using period in the two adjacent water using periods in the current year with the water using amount in the same period and adjacent months, determine the user with leakage in the leakage building, and further accurately judge the position of a leakage point in the region to be detected. Compared with the existing DMA-based partition management method, the leakage detection method can automatically analyze the water consumption in the area to be detected step by step so as to quickly determine the position of the leakage point, does not need to consume a large amount of manpower and time to check each user in the area to be detected one by one, and improves the detection efficiency.
As shown in fig. 2, an embodiment of the present application further provides a water supply pipe network leakage detection system based on an electromagnetic water meter, where the system 500 includes an obtaining module 501 and a detecting module 502.
Specifically, the obtaining module 501 is configured to obtain, by using the electromagnetic water meter, water consumption data when it is detected that a leakage area to be detected exists in the water supply network, where the water consumption data includes first data and second data of two adjacent water usage periods of the area to be detected in the current year, third data of the area to be detected corresponding to the second water usage period of the two adjacent water usage periods in the previous year, fourth data and fifth data of two adjacent water usage periods of each user in the area to be detected in the current year, and sixth data of the user corresponding to the second water usage period in the previous year; and determining seventh data and eighth data of each building in the area to be tested in two adjacent water using periods in the current year and ninth data of the building corresponding to the second water using period in the previous year according to a preset virtual building table, fourth data, fifth data and sixth data corresponding to the area to be tested, wherein the virtual building table is used for describing the corresponding relation between the building and users in the area to be tested.
The detection module 502 is configured to determine a leaking building according to the first data, the second data, the third data, the seventh data, the eighth data, and the ninth data, where the leaking building is a building in which a leak exists in the second water usage period in the area to be detected, and determine a user in the leaking building that the leak exists in the second water usage period according to the fourth data, the fifth data, and the sixth data.
Optionally, the water supply pipe network leakage detection system provided by the embodiment of the application further includes a prompt module 503, and the prompt module 503 is configured to send a prompt message indicating that leakage exists to the user when the leakage exists.

Optionally, if the second ratio is smaller than the first ratio and smaller than the third ratio, the building is determined to be a leakage building, and physical leakage exists in the second water using period of the leakage building.
