However, at present, each water supply company regularly analyzes the water consumption of large-caliber water meters, which takes a lot of time and has low analysis efficiency.

[0003] Therefore, the prior art needs to be improved. Summary of the invention

[0004] The purpose of this application is to analyze the metering characteristics of water meters, combine the user's water usage characteristics, and reasonably select the water meter caliber that matches the water usage.

[0009] The above scheme of the present application obtains the user's commonly used water volume, calculates the metering efficiency of the user's current water meter based on the user's commonly used water volume, and determines whether the current water metering efficiency is stable based on the metering efficiency. If the metering efficiency is stable, it means that the current water meter matches the user's water consumption and there is no need to replace the water meter. When the metering efficiency of the user's water meter is unstable, it means that the user's current water meter does not match the user's water consumption and it is necessary to replace the water meter that matches the water consumption to ensure the metering efficiency and the benefits of the user and the water supply company. It dynamically analyzes the user's water use characteristics and the water metering characteristics to ensure that the user's water consumption matches the water meter caliber, that is, the average water consumption is close to the common flow of the water meter, to ensure accurate metering, reasonable billing, and reduce the water meter maintenance cost, and at the same time, effectively reduce the production and sales difference rate.

[0020] Calculate the common flow rate, common flow rate = measured water volume / number of days of water use / time of water use.

[0021] In the above scheme of the present application, the acquisition of commonly used flow is calculated through multiple parameters. The number of days for measurement is determined according to the statistical period, and the daily water use time is determined according to the nature of water use.

When the ratio is not within the predetermined range, it means that the current user water meter does not match the user's water usage, and there is a phenomenon of "a big horse pulling a small cart" or "a small horse pulling a big cart", that is, the metering efficiency of the current caliber water meter is unstable.

[0024] Optionally, in the water meter selection and matching method, the method of calculating the metering efficiency of the current water meter according to the user's common flow rate and judging whether the metering efficiency of the current water meter is stable also includes:

[0027] Among the filtered water meters, the parameters of the water meters whose common flow rates are between the Q2 value and the Q3 value of the water meters are filtered and displayed.

[0028] The above-mentioned solution of the present application can not only analyze whether the user's usual flow rate matches the current water meter, but also intelligently match the water meter caliber with the best metering efficiency according to the user's current water usage.

If the metering efficiency is stable, it means that the current water meter matches the user's water consumption and there is no need to replace the water meter. When the metering efficiency of the user's water meter is unstable, it means that the user's current water meter does not match the user's water consumption and it is necessary to replace the water meter that matches the water consumption to ensure the metering efficiency and the benefits of the user and the water supply company. It dynamically analyzes the user's water use characteristics and the water metering characteristics to ensure that the user's water consumption matches the water meter caliber, that is, the average water consumption is close to the common flow of the water meter, to ensure accurate metering, reasonable billing, and reduce the water meter maintenance cost, and at the same time, effectively reduce the production and sales difference rate.

[0045] The following is combined with Figure 1-3 This application is described in further detail.

[0046] This application discloses a water meter selection and matching method, which can intelligently match water meter parameter types according to the user's water consumption, improve the metering efficiency of the water meter, and protect the rights and interests of users and water supply companies. The method described in this application is used as a reference for whether the user's water meter is matched, and provides better water meter parameters for users to choose. For details, please refer to Figure 1 , is a flowchart of the steps of the method, the method comprising:

[0047] S1. Obtain the user's regular traffic;

[0048] In step S1, the user's common flow, that is, the measured water volume, is obtained. The user's water usage characteristics are analyzed based on the measured water volume, so as to intelligently select a matching water meter caliber. Step S1 specifically includes:

[0049] Obtain the measured water volume; the measured water volume is the water consumption measured by the water meter installed by the water supply enterprise, that is, the measured water volume of the water supply enterprise.

[0050] Get the statistical period; based on the company's meter reading period, that is, the number of days between the current meter reading date and the last meter reading date.

[0051] Determine the number of days for measurement; the statistical cycle is used to determine the number of days for measurement. Generally, statistics are conducted in natural months, such as once a month, once every two months, or once every three months. The longer the cycle, the more stable the metering efficiency of the water meter. For example, if the water consumption for three or four days is counted, the fluctuation of the water volume is relatively large, and the influence of accidental factors is large, the deviation will be large. It may be that the user is on a business trip or friends come to the user's home for a party these days, which may cause a large error.

[0052] Determine the daily water use time; determine the daily water use time, that is, how long is the water use time in a day. Under normal circumstances, residents' lives and administrative institutions use water for 4 hours a day, industry, business services use water for 8 hours a day, and special water use for 12 hours a day.

[0053] Calculate the common flow rate, common flow rate = measured water volume / water use days / water use time. In this application, the common flow rate is calculated by dividing the measured water volume by the water use days and water use time to calculate the user's common flow rate.

[0054] In the method described in the present application, the user's water meter is matched according to the user's water usage and the metering characteristics of the water meter. Therefore, the method further includes:

[0055] S0. Set water meters with different parameters and flow information, create a matching table and save it;

[0056] The water meter parameters include: water meter model, water meter caliber and metering level;

[0057] The flow information includes: maximum monthly water consumption and minimum monthly water consumption.

[0058] Water meters with different parameters and flow information are pre-set, and a matching table is established for storage. The appropriate water meter can be intelligently matched after analyzing the user's usual flow. The water meter parameters and flow information are matched. Different water meter parameters have different metering characteristics. The appropriate water meter can be matched according to the user's usual flow.

[0059] As for whether the water meter is matched, the important judgment factor is the metering efficiency of the water meter, so the following steps are also included:

[0060] S2. Calculate the metering efficiency of the current water meter based on the user's common flow rate, and determine whether the metering efficiency of the current water meter is stable; determine whether the metering efficiency of the water meter is stable, so as to know whether the user's current water consumption matches the water meter. If the metering efficiency is stable, there is no need to replace the current water meter. For details, refer to Figure 2 , is a flow chart of step S2, wherein the step of determining whether the water metering efficiency is stable comprises:

[0061] S201. Derive the metering characteristics of the current water meter based on the parameter information of the current user's water meter; the parameter information of each water meter corresponds to the flow information of the water meter; in the above steps, the parameter information of the user's current water meter can be directly obtained, and the parameter information can be obtained from the manual or by looking up the model. The water consumption information of the current water meter can be obtained from the user's water meter parameter information. Different water meters have corresponding flow information. The above scheme mentioned that the flow information of the water meter includes the maximum monthly water consumption and the minimum monthly water consumption. After obtaining the maximum monthly water consumption and the minimum monthly water consumption of the water meter, it is necessary to determine whether the water meter matches the user's monthly water consumption, so it also includes the steps:

[0062] S202. Divide the user's monthly water consumption by the maximum monthly water consumption of the current water meter to obtain a ratio. When the ratio is not within the predetermined range, it is determined that the current water meter metering efficiency is unstable. The maximum monthly water consumption of the current water meter is compared with the user's monthly water consumption, and the maximum monthly water consumption is determined to determine whether the maximum monthly water consumption is reasonable. In the embodiment of the present application, the user's monthly water consumption is divided by the maximum monthly water consumption of the current water meter to obtain a ratio. This is to obtain the relationship between the monthly water consumption and the maximum monthly water consumption of the water meter. If the ratio is greater than 1, it indicates that the read water consumption is greater than the maximum monthly water consumption. At this time, the user's monthly water consumption has exceeded the overload flow of the current water meter. Obviously, it indicates that the current water meter metering efficiency is unstable and does not match the current user's monthly water consumption. It is necessary to replace a water meter with a slightly larger diameter to match the user's monthly water consumption. In this application, the specific predetermined range of the ratio can be set by the user, the upper limit must be less than or equal to 1, and the lower limit can be set by the user. If the ratio between the user's monthly water consumption and the maximum monthly water consumption of the water meter indicates that the water meter metering efficiency is stable, it still needs to be determined once. The specific steps include:

[0063] S203. When the ratio is within a predetermined range, the calculated common flow rate is compared with the boundary flow value Q2 of the current water meter and the common flow value Q3;

[0064] S204. When the normal flow rate is between Q2 and Q3, it is determined that the current water meter measurement efficiency is stable.

[0065] The commonly used flow calculated by the above scheme is compared with the boundary flow value Q2 and the commonly used flow value Q3 of the current water meter. The values ​​of Q2 and Q3 can be found through the product model. When the commonly used flow is between Q2 and Q3, the metering efficiency is determined to be stable. A certain range of errors can be allowed at the critical values ​​of Q2 and Q3, which can be set by yourself. When the metering efficiency is reasonable, it indicates that the user's current water meter matches the user's water consumption.

[0066] When the metering efficiency of the current water meter is unreasonable, it indicates that the current user's water meter does not match the user's water usage, so the following steps are also included:

[0067] S3. If the current metering efficiency of the water meter is unreasonable, match the water meter parameters for reference to the user.

[0068] When the current user water meter's metering efficiency is unreasonable, the water meter needs to be replaced with a matching caliber. Therefore, through the previous matching table, the water meter parameters for reference can be matched to the user for reference. The specific matching steps are:

[0069] Filter to meet the average water consumption = meter reading water volume / meter reading days / water use time;

[0070] Among the filtered water meters, the parameters of the water meters whose average water consumption is between the Q2 value and the Q3 value of the water meter are filtered and displayed.

[0071] In a preferred embodiment of the present application, the specific steps of matching the water meter include two determinations. First, the ratio of the user's monthly water consumption to the maximum monthly water consumption of the water meter must be within a predetermined range. After the first screening, there will be one or more water meters that meet the requirements. Then, among the screened water meters, the parameters of the water meters whose average water consumption is between the Q2 value and the Q3 value of the water meter are screened and displayed for user reference.

[0072] In the embodiments of the present application, the specific explanations of Q1, Q2, Q3 and Q4 are as follows:

[0073] Minimum flow rate (Q1): The minimum flow rate at which the water meter indication is required to meet the maximum allowable error.

[0074] Boundary flow (Q2): The flow that appears between the commonly used flow Q3 and the minimum flow Q1, dividing the flow range into two areas, a "high area" and a "low area", each with a specific maximum allowable error.

[0075] Normal flow rate (Q3): The maximum flow rate under rated working conditions. At this flow rate, the water meter should work normally and meet the maximum allowable error requirements.

[0076] Overload flow (Q4): The water meter is required to meet the maximum allowable error requirements for a short period of time and then maintain the maximum flow rate of the metering characteristics under rated working conditions.

[0077] Reasonable water meter selection principles: When selecting the water meter diameter, the maximum water consumption must not exceed the overload flow of the water meter, the minimum water consumption must be greater than the minimum flow of the water meter, and the average water consumption is close to the common flow of the water meter. The water meter diameter cannot be selected simply based on the pipe diameter.

[0078] In the embodiment of the present application, when implemented specifically, it includes:

[0079] Method 1: derive the flow information of the current water meter according to the parameter information of the current user's water meter;

[0080] According to the user's meter reading water consumption, estimate the user's monthly water consumption = meter reading water consumption / meter reading days*30;

[0081] Judgment 1: When the user's monthly water consumption is greater than the maximum monthly water consumption of the current water meter, it is judged that the current water meter is too small and it is recommended to replace it with a water meter with a larger diameter.

[0082] Judgment 2: When the user's monthly water consumption is less than the minimum monthly water consumption of the current caliber, it is judged that the current water meter caliber is too large, and it is recommended to replace the water meter with a smaller caliber.

[0083] Method 2: deriving the flow information of the current water meter according to the parameter information of the current user's water meter;

[0084] According to the user's measured water volume, estimate the user's average hourly water consumption = measured water volume / meter reading days / daily water usage time.

[0085] Compare the average hourly water consumption with the overload flow, minimum flow and normal flow of the current caliber water meter.

[0086] Judgment 1: When the average hourly water consumption is greater than the overload flow Q4 of the current caliber water meter, it is judged that the current water meter caliber is too small. According to the average hourly water consumption, a water meter caliber (expanded diameter) with a common flow rate is selected and replaced with a water meter of a different caliber.

[0087] Judgment 2: When the average hourly water consumption is less than the minimum flow Q1 of the current caliber water meter, it is judged that the current water meter caliber is too large. According to the average hourly water consumption, a water meter caliber (reduced diameter) with a common flow rate is selected and replaced with a water meter of a different caliber.

[0088] Judgment 3: When the average water consumption and the common flow of the current caliber water meter are between Q2 and Q3, the user's water consumption basically matches the caliber of the current water meter, and there is no need to expand or reduce the diameter to replace the water meter.

[0089] Method 2 can be used as a supplement to Method 1, or it can be used independently.

[0090] Through the above-mentioned scheme of the present application, it is possible to analyze whether the user's water meter matches according to the user's water usage situation, and if the user's water meter does not match, matching water meter parameters can be provided for the user's reference, so as to improve the metering efficiency of the user's water meter and ensure the interests of the user and the water supply company.

[0091] Furthermore, based on the above method, the present application also discloses a water meter selection and matching system, see Figure 3 , is a structural block diagram of the system, which includes:

[0092] The commonly used traffic acquisition module 100 is used to acquire the commonly used traffic of the user;

[0093] The metering efficiency calculation module 200 is used to calculate the metering efficiency of the current water meter according to the user's common flow rate, and determine whether the metering efficiency of the current water meter is stable;

[0094] The water meter matching module 300 is used to match the water meter parameters for reference to the user when the metering efficiency of the current water meter is unstable.

[0095] In the embodiment of the present application, by obtaining the user's commonly used water volume, the metering efficiency of the user's current water meter is calculated based on the user's commonly used water volume, and based on the metering efficiency, it is determined whether the current water meter metering efficiency is stable. If the metering efficiency is stable, it indicates that the current water meter matches the user's water consumption and there is no need to replace the water meter. When the metering efficiency of the user's water meter is unstable, it means that the user's current water meter does not match the user's water consumption and it is necessary to replace a water meter that matches the water consumption to ensure the metering efficiency and the benefits of the user and the water supply company. The user's water use characteristics and the water meter metering characteristics are dynamically analyzed to ensure that the user's water consumption matches the water meter caliber, that is, the average water consumption is close to the common flow of the water meter, to ensure accurate metering, reasonable billing, and reduce the water meter maintenance cost. At the same time, the production and sales difference rate is effectively reduced.

[0096] The specific implementation of each of the above modules has been described in the method steps, so it will not be repeated here.

[0101] In the embodiment of the present application, a correspondence is established between the water meter parameters and the flow information and saved, so as to intelligently match the water meter corresponding to the water meter parameters according to the actual user-end flow information.

[0102] In response to the above method, the present application also discloses a device for implementing water meter selection and matching, which includes a memory and a processor, wherein the memory stores a computer program that can be loaded and executed by the processor, such as the water meter selection and matching method described above.
