Technical Field

[0001] The present invention relates to the technical field of water-saving management, and in particular to a water-saving management optimization method based on extraction, supply, use and drainage. Background Art

[0002] Water is the source of life, and protecting water resources is essential to maintaining ecological balance and biodiversity. By saving water, we can reduce water pollution and overexploitation, and reduce the negative impact on the natural environment. Globally, the contradiction between water supply and demand is becoming increasingly prominent. With the influence of factors such as population growth, economic development and climate change, many regions are facing serious water shortages. Therefore, water conservation has become a key measure to maintain ecological balance and social stability. Water is also a basic resource to support social and economic development. The rational use of water resources is essential for the sustainable development of society. Water conservation can reduce water use costs, improve water resource utilization efficiency, and promote sustainable economic growth.

[0003] However, at present, when judging whether a user needs to save water, the user's actual water consumption is compared with the standard value to judge whether the user needs to save water. This method does not take into account the relationship between water supply and actual water consumption, resulting in a low accuracy rate of the judgment result;

[0004] To this end, the present invention proposes a water-saving management optimization method based on extraction, supply, use and drainage. Summary of the invention

[0005] The purpose of the present invention is to propose a water-saving management optimization method based on water supply, use and drainage to solve the problems raised in the above background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Based on the water-saving management optimization method of supply, use and drainage, the specific water-saving management optimization method is as follows:

[0008] Step S1, collecting historical water consumption data and historical water supply data corresponding to the target building;

[0009] Step S2, determining the water optimization demand corresponding to the target building based on historical water consumption data and historical water supply data;

[0012] Step S5, performing corresponding water-saving operations according to the user's water-saving level.

[0013] Furthermore, the historical water usage data is the daily water intake corresponding to each household in the target building in the previous quarter;

[0022] Step S26, if the water supply overflow index corresponding to the target building is less than or equal to the overflow index threshold, the daily water consumption corresponding to each user in the target building is compared with the rated daily water consumption. When the rated daily water consumption is less than the daily water consumption, no operation is performed. When the rated daily water consumption is greater than or equal to the daily water consumption, the value of the water-saving demand coefficient of the corresponding user is increased by one and the next step is entered;

[0023] Step S27, if the water-saving demand coefficient is greater than the water-saving coefficient threshold, the corresponding user is recorded as a user to be water-saving;

[0024] If the water-saving demand coefficient is less than or equal to the water-saving coefficient threshold, no operation is performed.

[0025] Furthermore, the step S3 includes the following sub-steps:

[0026] Step S31, obtaining the historical water consumption data corresponding to the target building, and obtaining the daily water consumption RYSnm of each user in the target building, where n is the user number, m is the date number, n=1, 2, ..., z, z is a positive integer, and m=1, 2, ..., 90;

[0031] Step S36, if the daily average water consumption is within the first boundary interval, the water-saving level of the corresponding user is recorded as level one water-saving;

[0032] If the average daily water consumption is within the second boundary interval, the corresponding user's water-saving level will be recorded as level 2 water-saving;

[0033] If the average daily water consumption is within the third dividing range, the corresponding user's water-saving level will be recorded as level three water-saving.

[0034] Furthermore, the water-saving demand of users corresponding to the first-level water-saving level is lower than the water-saving demand of users corresponding to the second-level water-saving level;

[0035] The water-saving demand of users corresponding to the second level of water-saving is lower than the water-saving demand of users corresponding to the third level of water-saving.

[0036] Furthermore, the step S4 includes the following sub-steps:

[0037] Step S41, obtaining the daily water consumption of the user to be water-saving in the previous week and recording it as the actual water consumption;

[0043] Step S46, if any one of the first to sixth slopes of the user to be water-saving is greater than zero, the number of times the slope is greater than zero is counted and the process proceeds to the next step;

[0044] Step S47, when the number of times the slope is greater than zero is less than or equal to three times, the water-saving level of the user to be water-saving is recorded as level 2 water-saving;

[0045] When the number of times the slope is greater than zero is greater than three times, the first to sixth slopes are added to obtain the total slope of the users to be water-saving, and the total slope of the users to be water-saving is compared with the slope threshold;

[0046] Step S48, if the total slope is less than or equal to the slope threshold, the water-saving level of the user to be water-saving is recorded as level 2 water-saving;

[0047] If the total slope is greater than the slope threshold, the water-saving level of the user to be water-saving is recorded as level three water-saving.

[0048] Furthermore, the calculation process of the first slope is specifically as follows:

[0049] The water consumption in the water consumption trend diagram is used as the ordinate, and the date in the water consumption trend diagram is used as the abscissa, so as to construct a rectangular coordinate system, and obtain the position coordinates of the first water consumption node and the second water consumption node in the rectangular coordinate system respectively. The position coordinates of the first water consumption node are (x1, y1), and the position coordinates of the second water consumption node are (x2, y2). Therefore, the first slope between the second water consumption node and the first water consumption node is:

[0050] First slope = (y2-y1) / (x2-x1).

[0051] Furthermore, the water-saving operation is specifically as follows:

[0052] If the user's water-saving level is level one, it is determined that the user does not need to save water;

[0053] If the user's water-saving level is level 2, water-saving equipment will be installed in the corresponding user's residence;

[0054] If the user's water-saving level is level three, water-saving equipment will be installed in the corresponding user's residence, and at the same time, the corresponding user's residence will be monitored for water leakage.

[0055] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0056] The present invention firstly collects the historical water use data and the historical water supply data corresponding to the target building, and then judges the water optimization demand corresponding to the target building according to the historical water use data and the historical water supply data. Meanwhile, on the one hand, the water use of the target building in the previous week is analyzed to obtain the water-saving level of each user in the target building, and on the other hand, the water use of the users to be water-saving in the previous week is analyzed to obtain the water-saving level corresponding to the users to be water-saving.

[0061] 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.

[0062] Example 1: Please refer to Figure 1 and Figure 2 As shown, the technical solution provided by the present invention is: a water-saving management optimization method based on water supply, use and drainage, and the method is specifically as follows:

[0063] Step S1, collect historical water usage data and historical water supply data corresponding to the target building, wherein the historical water usage data is specifically the daily water intake corresponding to each household in the target building in the previous quarter; the historical water supply data is the historical total water supply of the target building in the previous quarter.

[0064] Step S2, determining the water optimization demand corresponding to the target building based on historical water consumption data and historical water supply data;

[0065] In this embodiment, step S2 includes the following sub-steps:

[0066] Step S21, obtaining the historical water consumption data corresponding to the target building, and then adding up the daily water consumption of each household in the building to obtain the historical total water consumption LYS of the building in the previous quarter;

[0067] Step S22, obtaining the historical water supply data corresponding to the target building, and obtaining the historical total water supply LGS of the target building in the previous quarter;

[0068] Step S23, calculating the water supply overflow index GYC corresponding to the target building by a formula, the specific formula is:

[0069] GYC=(LGS-LYS) / LGS×100%;

[0070] Step S24, comparing the water supply overflow index corresponding to the target building with the overflow index threshold;

[0071] Step S25, if the water supply overflow index corresponding to the target building is greater than the overflow index threshold, water saving optimization is performed on the target building;

[0072] Step S26: If the water supply overflow index corresponding to the target building is less than or equal to the overflow index threshold, it is determined that the target building as a whole does not need to be optimized for water conservation, then the daily water consumption corresponding to each user in the target building is compared with the rated daily water consumption. When the rated daily water consumption is less than the daily water consumption, no operation is performed. When the rated daily water consumption is greater than or equal to the daily water consumption, the value of the water conservation demand coefficient of the corresponding user is increased by one and the next step is entered;

[0073] The rated daily water consumption refers to the amount of water that each household is approved or required to use for living, production and other purposes in one day. The initial value of the standard water-saving demand coefficient is zero.

[0074] Step S27, if the water-saving demand coefficient is greater than the water-saving coefficient threshold, the corresponding user is recorded as a user to be water-saving; if the water-saving demand coefficient is less than or equal to the water-saving coefficient threshold, no operation is performed.

[0075] Step S3, analyzing the water consumption of the target building in the previous week to obtain the water saving level of each user in the target building;

[0076] In this embodiment, step S3 includes the following sub-steps:

[0077] Step S31, obtaining the historical water consumption data corresponding to the target building, and obtaining the daily water consumption RYSnm of each user in the target building, where n is the user number, m is the date number, n=1, 2, ..., z, z is a positive integer, and m=1, 2, ..., 90;

[0078] Step S32, adding up the daily water consumption of each household in the target building and taking the average value to obtain the daily average water consumption RJSm of each household in the target building;

[0079] Step S33, the daily water consumption variance YFCn corresponding to each household of the target building is calculated by the formula, and the specific formula is as follows:

[0080] ;

[0081] Step S34, obtain the first water consumption delimiting value DYF corresponding to the target building by subtracting the daily water consumption variance from the daily average water consumption; obtain the second water consumption delimiting value DEF corresponding to the target building by adding the daily average water consumption variance to the daily average water consumption, and obtain the first delimiting interval [0, DYF], the second delimiting interval (DYF, DEF], and the third delimiting interval (DEF, +∞) corresponding to the target building according to the first water consumption delimiting value and the second water consumption delimiting value;

[0082] Step S35, collecting the weekly water consumption of each user in the target building in the previous week, then adding up the weekly water consumption and taking the average to obtain the daily average water consumption of the corresponding user in the previous week, and comparing the daily average water consumption with the first boundary interval, the second boundary interval and the third boundary interval;

[0083] Step S36: if the average daily water consumption is within the first boundary interval, the water-saving level of the corresponding user is recorded as level one water-saving; if the average daily water consumption is within the second boundary interval, the water-saving level of the corresponding user is recorded as level two water-saving; if the average daily water consumption is within the third boundary interval, the water-saving level of the corresponding user is recorded as level three water-saving;

[0084] Among them, the water-saving demand of users corresponding to the first-level water-saving level is lower than the water-saving demand of users corresponding to the second-level water-saving level; the water-saving demand of users corresponding to the second-level water-saving level is lower than the water-saving demand of users corresponding to the third-level water-saving level.

[0085] Step S4, analyzing the water consumption of the water-saving users in the previous week to obtain the water-saving level corresponding to the water-saving users;

[0086] In this embodiment, step S4 includes the following sub-steps:

[0087] Step S41, obtaining the daily water consumption of the user to be water-saving in the previous week and recording it as the actual water consumption;

[0088] Step S42, as Figure 2 As shown, a water consumption trend diagram of the water-saving user to be water-saving is drawn according to the actual water consumption of the water-saving user to be water-saving, and the first water consumption node, the second water consumption node, the third water consumption node, the fourth water consumption node, the fifth water consumption node, the sixth water consumption node and the seventh water consumption node in the water consumption trend diagram are obtained respectively;

[0089] Step S43, calculating a first slope between the second water consumption node and the first water consumption node, and a second slope between the third water consumption node and the second water consumption node;

[0090] The calculation process of the first slope is as follows: the water consumption in the water consumption trend diagram is used as the ordinate, and the date in the water consumption trend diagram is used as the abscissa, so as to construct a rectangular coordinate system, and obtain the position coordinates of the first water consumption node and the second water consumption node in the rectangular coordinate system respectively. The position coordinates of the first water consumption node are (x1, y1), and the position coordinates of the second water consumption node are (x2, y2). Therefore, the first slope between the second water consumption node and the first water consumption node is:

[0091] First slope = (y2-y1) / (x2-x1);

[0092] Step S44, similarly, calculate the third slope between the fourth water use node and the third water use node, the fourth slope between the fifth water use node and the fourth water use node, the fifth slope between the sixth water use node and the fifth water use node, and the fifth slope and the sixth slope between the seventh water use node and the sixth water use node;

[0093] It should be noted that, for any of the first to sixth slopes, if the value is greater than zero, it means that the water consumption trend of the user to be water-saving is increasing; if the value is less than zero, it means that the water consumption trend of the user to be water-saving is decreasing;

[0094] Step S45, if the first to sixth slopes of the user to be water-saving are all less than zero, the water-saving level of the user to be water-saving is recorded as level one water-saving;

[0095] Step S46, if any one of the first to sixth slopes of the user to be water-saving is greater than zero, the number of times the slope is greater than zero is counted and the process proceeds to the next step;

[0096] Step S47, when the number of times the slope is greater than zero is less than or equal to three times, the water-saving level of the user to be water-saving is recorded as level 2 water-saving;

[0097] When the number of times the slope is greater than zero is greater than three times, the first to sixth slopes are added to obtain the total slope of the users to be water-saving, and the total slope of the users to be water-saving is compared with the slope threshold;

[0098] Step S48, if the total slope is less than or equal to the slope threshold, the water-saving level of the user to be water-saving is recorded as level 2 water-saving;

[0099] If the total slope is greater than the slope threshold, the water-saving level of the user to be water-saving is recorded as level three water-saving.

[0100] Step S5, performing corresponding water-saving operations according to the user's water-saving level, wherein the water-saving operations are specifically as follows:

[0101] If the user's water-saving level is level one, it is determined that the user does not need to save water;

[0102] If the user's water-saving level is level 2, water-saving equipment will be installed in the corresponding user's residence;

[0103] If the user's water-saving level is level three, water-saving equipment will be installed in the corresponding user's residence, and at the same time, the corresponding user's residence will be monitored for water leakage.

[0104] 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.
