Description

Technical Field

[0001] The invention belongs to the field of urban water use and relates to a water balance technology, in particular to a digital-based water balance test system and a test method. Background Art

[0002] Water balance test is an effective method for scientific management of water users, and is also the basis for further improving urban water conservation. The significance of water balance test lies in that it can fully understand the status of the water pipe network of water users, the water use status of each part (unit), draw a water balance diagram, and find out the water balance relationship and reasonable water use level based on the measured water volume data, take corresponding measures, tap the water use potential, and achieve the purpose of strengthening water management and improving the level of reasonable water use.

[0003] The current water balance test usually follows the principle of solving problems as they arise. This method does not combine the historical water balance conditions of each water-using node or water-using area for adaptation testing. At the same time, the current water balance test method only conducts leakage analysis on the water-using area or water-using node from a single situation, and does not conduct leakage analysis on the water-using area or water-using node from different situations. The leakage analysis is not comprehensive;

[0004] To this end, the present invention proposes a digital-based water balance test system and test method. Summary of the invention

[0030] Then, the real-time water consumption, real-time drainage, real-time circulating water output and real-time series water output of the water-using area during the water balance test are obtained, and the dynamic output deviation value of the water-using area is calculated;

[0031] The dynamic inlet deviation value and the dynamic outlet deviation value are added together to obtain the dynamic water leakage volume when the water balance test is carried out in the water use area;

[0032] According to the above operation, the dynamic water loss when the water balance test is performed in multiple groups of water use areas is obtained according to the number of water balance tests in the water use areas;

[0033] The real-time water inflow, real-time circulating water inflow and real-time series water inflow are added together to obtain the total real-time water inflow of the water-using area.

[0059] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0060] Figure 1 is the overall system block diagram of the present invention;

[0061] Figure 2 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0062] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Example 1: Please refer to Figure 1 As shown, the technical solution provided by the present invention is: a water balance test system based on digitalization, including a storage module, a condition analysis module, a data acquisition module, a static test module, a dynamic test module, an intelligent grading module and a server;

[0064] The storage module is used to store historical test data of each water use area, wherein the historical test data is the number of tests of the water use area, the number of test abnormalities, and the test water loss during each test abnormality. Specifically, the water use area can be a residential area, a campus, an industrial park, etc. In this embodiment, the water use area is preferably a residential area;

[0065] In this embodiment, the storage module is connected to the status analysis module, and the status analysis module is used to analyze the historical test status of the water balance of the water use area. The analysis process is as follows:

[0066] The water-using area is marked as i, where i is the number of the water-using area;

[0067] Obtain the number of tests and the number of test anomalies in the water-using area, and compare the number of test anomalies with the number of tests to obtain the test anomaly rate YLi of the water-using area;

[0068] Then, the test leakage water volume of each abnormal test in the water use area is obtained, and the test leakage water volume of each abnormal test is added and divided by the number of abnormal tests to obtain the abnormal leakage water volume LSi of the water use area;

[0069] The test control value CGi of the water use area is calculated by the formula, and the specific formula is as follows:

[0070] CGi=YLi×a1+LSi×a2; where a1 and a2 are weight coefficients with fixed values;

[0071] According to the test control value interval to which the test control value belongs, the number of water balance tests corresponding to the water use area is obtained, specifically:

[0072] If the test control value belongs to the first test control value interval, the number of water balance tests in the water-using area is the first number;

[0073] If the test control value belongs to the third test control value interval, the number of water balance tests for the water-using area is the second number;

[0074] If the test control value belongs to the third test control value interval, the number of water balance tests in the water use area is the third number; wherein the right endpoint of the first test control value interval is less than the left endpoint of the second test control value interval, the right endpoint of the second test control value interval is less than the left endpoint of the third test control value interval, the first number is less than the second number, and the second number is less than the third number;

[0075] The situation analysis module sends the number of water balance tests corresponding to the water use area to the server, and the server sends the number of water balance tests corresponding to the water use area to the data acquisition module.

[0076] In practice, the data acquisition module is used to collect real-time water balance data of the water use area multiple times according to the number of water balance tests, and send the real-time water balance data to the server, and the server sends the real-time water balance data to the static test module and the dynamic test module;

[0077] What needs to be explained specifically is that the real-time water balance data refers to the real-time water inflow, real-time water storage, real-time water consumption, real-time drainage, real-time circulating water inflow, real-time circulating water outflow, real-time series water inflow and real-time series water outflow when the water-using area is tested for water balance in a dynamic state, and the real-time water inflow, real-time water storage, real-time drainage, real-time circulating water inflow, real-time circulating water outflow, real-time series water inflow and real-time series water outflow when the water-using area is tested for water balance in a static state. In reality, the dynamic state refers to the water use by the water-using units in the water-using area, and the static state refers to the water use by no water-using units in the water-using area. The corresponding data can be obtained by monitoring the flow of the water inlet and outlet of the water supply pipe in the water-using area, as well as the circulating pipe and series pipe connected to the water supply pipe;

[0078] Among them, the real-time water inlet is the amount of water input into the corresponding water inlet of the water supply pipe in the water-using area, the real-time water storage is the amount of water in the water supply pipe in the water-using area, the real-time water consumption is the real-time water storage of each water-using unit in the water-using area, and the real-time drainage is the amount of water discharged from the corresponding drainage outlet of the water supply pipe in the water-using area.

[0079] On the one hand, the dynamic test module is used to test the water balance of the water-using area in a dynamic state. The test process is as follows:

[0080] Obtain the real-time water inflow SJio, real-time circulating water inflow SXRio, real-time series water inflow SCRio and real-time water storage SCio when the water balance test is carried out in the water-using area; o is the number of the real-time water balance data;

[0081] The dynamic feed deviation value SJLio during the water balance test in the water use area is calculated according to the formula SJPio = SJio + SXRio + SCRio - SCio;

[0082] Then, the real-time water consumption SHio, real-time water discharge SPio, real-time circulating water output SXCio and real-time series water output SCCio are obtained when the water balance test is carried out in the water use area;

[0083] The dynamic output deviation value SCLio of the water-using area is calculated according to the formula SCLio=SCio-SHio-SPio-SXCio-SCCio;

[0084] The dynamic inlet deviation value and the dynamic outlet deviation value are added together to obtain the dynamic water leakage volume when the water balance test is carried out in the water use area;

[0085] According to the above operation, the dynamic water loss when the water balance test is performed in multiple groups of water use areas is obtained according to the number of water balance tests in the water use areas;

[0086] The real-time water inflow, real-time circulating water inflow and real-time series water inflow are added together to obtain the total real-time water inflow of the water-using area. The dynamic leakage water ratio is compared with the total real-time water inflow to obtain the dynamic loss ratio of the water-using area each time the water balance test is performed;

[0087] The dynamic loss ratios during each water balance test are compared and traversed to obtain the maximum value of the dynamic loss ratios, and the maximum value of the dynamic loss ratios is used as the first loss ratio SH1i when the water use area performs a water balance test under a dynamic state;

[0088] The dynamic test module feeds back the first loss ratio of the water-using area when the water balance test is performed in the dynamic state to the server, and the server sends the first loss ratio of the water-using area when the water balance test is performed in the dynamic state to the intelligent grading module;

[0089] On the other hand, the static test module is used to test the water balance of the water-using area in a dynamic state. The test process is as follows:

[0090] Obtain the real-time water inflow, real-time circulating water inflow, real-time series water inflow and real-time water storage volume when conducting water balance test in the water-using area;

[0091] The static water intake deviation value when the water balance test is performed in the water use area is obtained by subtracting the real-time water storage volume from the sum of the real-time water intake, the real-time circulating water intake and the real-time series water intake;

[0092] Then, the real-time drainage volume, real-time circulating water output and real-time series water output are obtained when the water balance test is carried out in the water use area;

[0093] The real-time drainage volume, real-time circulating water volume and real-time series water volume are added together to obtain the static water volume, and the real-time water storage volume minus the static water volume is used to obtain the static water volume deviation value of the water use area.

[0094] The static water loss during water balance test in the water-using area is obtained by adding the static inlet deviation value and the static outlet deviation value.

[0095] Similarly, the static water loss during water balance tests in multiple water-using areas can be obtained;

[0096] The real-time water inflow, real-time circulating water inflow and real-time series water inflow are added together to obtain the total real-time water inflow of the water-using area. The leakage water ratio is compared with the total real-time water inflow to obtain the static loss ratio of the water-using area each time the water balance test is performed.

[0097] The static loss ratios during each water balance test are compared and traversed to obtain the maximum value of the static loss ratios, and the maximum value of the static loss ratios is used as the second loss ratio SH2i when the water use area is subjected to a water balance test in a static state;

[0098] The static test module feeds back the second loss ratio of the water use area when the water balance test is performed in a static state to the server, and the server sends the second loss ratio of the water use area when the water balance test is performed in a static state to the intelligent grading module.

[0099] In this embodiment, the intelligent grading module is used to intelligently grade the water balance of the water use area. The intelligent grading process is as follows:

[0100] Obtain the first loss ratio SH1i obtained when the water-using area is subjected to a water balance test in a dynamic state, and the second loss ratio SH2i obtained when the water-using area is subjected to a water balance test in a static state;

[0101] The loss value SHi of the water balance test in the water-using area is calculated by the formula SHi=SH1i×b1+SH2i×b2; where b1 and b2 are weight coefficients with fixed values, and b1=b2;

[0102] If the loss value is less than the first loss threshold, a loss normal signal is generated;

[0103] If the loss value is greater than or equal to the first loss threshold and the second loss threshold, a loss abnormality signal is generated;

[0104] If the loss value is greater than or equal to a second loss threshold, a serious loss signal is generated; wherein the first loss threshold is less than the second loss threshold;

[0105] The intelligent grading module feeds back the normal loss signal, abnormal loss signal or severe loss signal to the server, and the server sends the normal loss signal, abnormal loss signal or severe loss signal to the display module. The display module is used to display the signal generated when the water balance test is performed on the user area. In practice, the display module is a display screen that can be connected to the server.

[0106] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.

[0107] Example 2: Figure 2 As shown, based on another concept of the same invention, a digital water balance test method is now proposed, comprising the following steps:

[0108] Step S100, analyzing the historical water balance test status of the water-using area in combination with the historical test data, and obtaining the number of water balance tests of the water-using area through analysis;

[0109] Step S200, collecting real-time water balance data of the water-using area multiple times according to the number of water balance tests;

[0110] Step S300, testing the water balance of the water-using area in a dynamic state in combination with the real-time water balance data, and obtaining a first loss ratio when the water balance test is performed in the water-using area in a dynamic state;

[0111] Step S400, testing the water balance of the water-using area in a dynamic state in combination with the real-time water balance data, and obtaining a second loss ratio when the water-using area is tested in a static state;

[0112] Step S500, intelligently classify the water balance of the water-using area according to the first loss ratio and the second loss ratio, and generate a normal loss signal, an abnormal loss signal or a serious loss signal.
