It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0024] Figure 1 is a flowchart of a water hardness measuring method for a water-related device provided by an embodiment of the present application. The embodiment of the present application is applicable to a water-related device which is not configured with a total dissolved solids probe and a hardness detection instrument. The method can be executed by a water hardness measuring device for a water-related device provided by an embodiment of the present application. The device can be realized in the form of software and / or hardware. In a specific embodiment, the device can be integrated in the water-related device. The following embodiments will be described by taking the device integrated in the water-related device as an example. Referring to Figure 1 , the method can specifically include the following steps:

[0025] At step 101, the history data of the total dissolved solids of the incoming water reported by the homogenous water equipment is obtained to obtain the history data of the total dissolved solids of the homogenous water of the target water-related equipment. The homogenous water equipment is other water-related equipment with the same water source as the target water-related equipment. This step can obtain the current total dissolved solids value of the incoming water of the target water-related equipment in real time, and facilitate determining the current total dissolved solids value of the target water-related equipment based on the history data of the total dissolved solids of the homogenous water.

[0026] It can be understood that due to environmental factors such as space, temperature and pressure, or based on cost and cost performance considerations, part of the water-related equipment cannot be installed with a TDS (total dissolved solids) probe. In order to obtain the current total dissolved solids value of the incoming water of the target water-related equipment in real time, the history data of the total dissolved solids of the incoming water reported by the homogenous equipment is obtained, which can facilitate real-time determination of the water hardness of the water-related equipment through the total dissolved solids prediction model.

[0027] Specifically, the water-related equipment can be a household water-related equipment such as a washing machine, a water purifier or a water softener, or an industrial water-related equipment.

[0028] Specifically, the homogenous water equipment can include water-related equipment located in the same geographical area as the target water-related equipment, for example, water-related equipment located in the same cell, the same street or the same county as the target water-related equipment.

[0029] Specifically, the homogenous water equipment can also include other water-related equipment of the same company as the water supply company of the target water-related equipment. The water supply company can be understood as a water company or a water service company.

[0030] Specifically, a total dissolved solids database can be established in advance to store the history data of the total dissolved solids of the incoming water reported by the water-related equipment including the homogenous water equipment.

[0031] Specifically, the water-related equipment can be instructed to report the total dissolved solids value of the incoming water in real time after obtaining user authorization.

[0032] At step 102, the current total dissolved solids value of the incoming water of the target water-related equipment is determined based on the history data of the total dissolved solids of the homogenous water through a time series model. This step can conveniently determine the total dissolved solids value of the target water-related equipment in real time, and facilitate determining the current water hardness of the target water-related equipment based on the current total dissolved solids value of the incoming water of the target water-related equipment.

[0033] Specifically, the time series model can be a model common to water-related equipment in the same area or multiple homogenous water equipment, or a model dedicated to the target water-related equipment.

[0034] Specifically, the time series model can be a time series model with optimal model parameters after training, or a time series model with original model parameters without training.

[0035] Specifically, the model parameters of the original time series model can be optimized based on the time series corresponding to the historical data of the homologous water-soluble solid before step 102.

[0036] Specifically, the time series model can be an additive time series model, and the corresponding model expression can be:

[0037] y(t) = g(t) + s(t) + ∈ t

[0038] where y(t) represents the time series value at time t;

[0039] g(t) represents a trend item, representing the change trend of the time series on the non-periodic;

[0040] s(t) represents a periodic item, or a seasonal item;

[0041] ∈ t represents an error item or a residual item.

[0042] Specifically, the time series can also be a machine learning and deep learning model, for example, it can be a recurrent neural network model, a convolutional neural network, or a gradient boosting tree model.

[0043] Optionally, the process of determining the current total dissolved solid value of the target water-related equipment based on the historical data of the homologous water-soluble solid through the time series model includes:

[0044] predicting the current total dissolved solid value of the target water-related equipment based on the historical data of the homologous water-soluble solid through the time series model to obtain a model prediction result; determining a prediction result correction coefficient based on the weather information in the latest third time period in the region where the target water-related equipment is located; and determining the current total dissolved solid value of the target water-related equipment based on the prediction result correction coefficient and the model prediction result.

[0045] It can be understood that when the water source of the target water-related equipment is surface water, the total dissolved solid of the incoming water is greatly affected by the weather, for example, it may be reduced due to dilution in the rainy season, and it may be increased due to evaporation and concentration in the dry season.

[0046] Specifically, the prediction result correction coefficient can also be determined based on other information that affects the total dissolved solid of the water source of the target water-related equipment, for example, it can be based on user pipe material information, pipe usage time information, etc.

[0047] Optionally, the process of determining the current total dissolved solids value of the water inlet of the target water-related equipment based on the time series model and the historical data of the total dissolved solids of the water of the same source comprises: determining the current total dissolved solids value of the water inlet of the target water-related equipment based on the time series model and the historical data of the total dissolved solids of the water of the same source in a preset prediction period, for example, the total dissolved solids value of the water inlet of the target water-related equipment can be predicted every day.

[0048] In step 103, the current water hardness of the target water-related equipment is determined based on the current total dissolved solids value. Based on the historical data of the total dissolved solids of the water inlet reported by the water-related equipment of the same source as the historical data of the total dissolved solids of the water of the target water-related equipment, and based on the corresponding historical data, the current total dissolved solids value of the water inlet of the target water-related equipment is determined by the total dissolved solids prediction model, which can conveniently and timely obtain the current total dissolved solids value of the water inlet of the target water-related equipment. The current water hardness of the target water-related equipment is further determined based on the current total dissolved solids value of the water inlet of the target water-related equipment, and the water hardness is determined based on the relationship between the total dissolved solids of the water inlet and the water hardness, which can conveniently and timely calculate the water hardness of the water-related equipment.

[0049] It can be understood that the total dissolved solids of water contain various dissolved solids in water, including compounds of calcium and magnesium ions, etc., and the hardness of water is mainly composed of calcium and magnesium ions. In a large amount of water scene, such as daily drinking water scene, the hardness of water is positively correlated with the total dissolved solids of water. Therefore, based on the relationship between the total dissolved solids of the water inlet of the water-related equipment and the water hardness, the water hardness of the water-related equipment can be conveniently calculated.

[0050] Optionally, the process of determining the current water hardness of the target water-related equipment based on the current total dissolved solids value comprises: calculating the current water hardness of the target water-related equipment based on the current total dissolved solids value and the current sodium ion content of the water inlet of the target water-related equipment.

[0051] Specifically, the process of calculating the current water hardness of the target water-related equipment based on the current total dissolved solids value and the current sodium ion content of the water inlet of the target water-related equipment can be based on the following formula:

[0052]

[0053] wherein H i represents the current water hardness of the target water-related equipment, TDS i represents the current total dissolved solids value of the water inlet of the target water-related equipment, A, B and C are constants, wherein the value range of A is [0-5], the value range of B is [0, 5], and the value range of C is [10, 30]

[0054] Specifically, the current water sodium ion content of the target water-related equipment can be detected in real time on line, or can be set after offline detection based on a preset detection period. For example, the water hardness of the target water-related equipment can be sampled and detected at a fixed time every day, and the current water hardness of the target water-related equipment from the same time on the current day to the next day can be set as the corresponding detection result.

[0055] Specifically, the process of detecting the current water sodium ion content of the target water-related equipment offline may, for example, be based on flame photometry or atomic absorption spectrometry.

[0056] Specifically, the current water hardness of the target water-related equipment can also be determined based on the total dissolved solids value of the water and a pre-established mapping relationship between the total dissolved solids value of the water and the water hardness.

[0057] Specifically, the mapping relationship between the total dissolved solids value of the water and the water hardness can be stored using a total dissolved solids and hardness mapping table.

[0058] Specifically, the mapping relationship between the total dissolved solids value of the water and the water hardness can also be represented using a corresponding mapping function.

[0059] The water hardness measurement method for a water-related equipment provided by the embodiment of the application will be further described below. As shown in FIG. 1, the method can include the following steps: Figure 2

[0060] Step 201: Establishing a regional water-related equipment database including location information of regional water-related equipment, the regional water-related equipment including water intake homologous equipment.

[0061] Specifically, the regional water-related equipment can be understood as each water-related equipment authorized in a geographical location region or an administrative region, for example, water-related equipment in a province, a city, or a county.

[0062] Optionally, the regional water-related equipment database includes the equipment identifier of each water-related equipment, the regional hierarchy to which the water-related equipment belongs, and historical data of the total dissolved solids of the water.

[0063] Specifically, the regional hierarchy to which the water-related equipment belongs may, for example, be X province X city X district X street X community.

[0064] Optionally, the process of establishing the regional water-related equipment database including the location information of the regional water-related equipment includes: obtaining original location data of the regional water-related equipment reported by a user end; encrypting the original location data to obtain encrypted location data; and storing the encrypted location data in the regional water-related equipment database.

[0065] ​It can be understood that the position data of the wading device is designed for user privacy, and the privacy information of the user can be protected by encrypting the unknown data, and the query authority of unauthorized users is limited.

[0066] In step 202, the position information of the target wading device is obtained, and the target position range is determined based on the position information of the target wading device.

[0067] Optionally, the process of obtaining the position information of the target wading device and determining the target position range based on the position information of the target wading device includes: obtaining the street where the target wading device is located, and determining the corresponding street as the target position range.

[0068] In step 203, the water-inlet homologous device is determined based on the target position range through the regional wading device database.

[0069] Optionally, the process of determining the water-inlet homologous device based on the target position range through the regional wading device database includes:

[0070] The other wading devices located in the target position range are queried and obtained from the regional wading device database, and these wading devices are determined as the water-inlet homologous device.

[0071] In step 204, the homologous water dissolved solid historical data of the target wading device is obtained by obtaining the water-inlet total dissolved solid historical data reported by the water-inlet homologous device, and the water-inlet homologous device is other wading device with the same water source as the water-inlet of the target wading device.

[0072] Specifically, the water-inlet total dissolved solid historical data reported by the water-inlet homologous device can be stored in the aforementioned regional wading device database in advance, and the process of obtaining the homologous water dissolved solid historical data of the target wading device by obtaining the water-inlet total dissolved solid historical data reported by the water-inlet homologous device can include: querying the regional wading device database to obtain the total dissolved solid historical data of the water-inlet homologous device to obtain the homologous water dissolved solid historical data of the target wading device.

[0073] In step 205, the current water-inlet total dissolved solid value of the target wading device is determined based on the homologous water dissolved solid historical data through the time series model.

[0074] In step 206, the current water-inlet hardness of the target wading device is determined based on the current water-inlet total dissolved solid value.

[0075] Optionally, the regional wading device database further includes the water supply company information of the regional wading device.

[0076] Optionally, before step 201, the water hardness measuring method for the water-involved equipment provided by the embodiment of the present application further comprises: obtaining the water supply company information of the target water-involved equipment; querying the water-involved equipment database to obtain the candidate water-involved equipment located within the target location range; and obtaining the candidate water-involved equipment with the same water supply company information as the target water-involved equipment to obtain the water-inlet homologous equipment.

[0077] The embodiment of the present application can accurately determine the water-inlet homologous equipment of the target water-involved equipment, and further accurately determine the homologous water dissolved solid historical data of the target water-involved equipment, so as to accurately determine the current water hardness of the target water-involved equipment based on the corresponding homologous water dissolved solid historical data.

[0078] The water hardness measuring method for the water-involved equipment provided by the embodiment of the present application is further introduced below.

[0079] Optionally, when the time series model is a model dedicated to the target water-involved equipment, the homologous water total dissolved solid historical data comprises a first historical data set and a second historical data set, the first historical data comprises the homologous water total dissolved solid historical data of a continuous first time length, and the second historical data set comprises the homologous water total dissolved solid historical data of a recent second time length.

[0080] Specifically, the first historical data set may, for example, comprise the homologous water total dissolved solid historical data of a continuous 1 year or 2 years.

[0081] Specifically, the second historical data may, for example, comprise the homologous water total dissolved solid historical data of the previous 1 year or 2 years.

[0082] Optionally, as shown in FIG. 1, step 102 in the method for measuring the water hardness of the water-involved equipment may comprise the following steps. Figure 3 Figure 1 Step 1021, training the time series model based on the first historical data set to obtain a total dissolved solid prediction model.

[0083] Step 1021, training the time series model based on the first historical data set to obtain a total dissolved solid prediction model.

[0084] Optionally, the process of training the time series model based on the first historical data set to obtain the total dissolved solid prediction model comprises:

[0085] Obtaining a first time series composed of the historical data in the first historical data set.

[0086] Sliding the sliding time window on the first time series to obtain a plurality of sample time series.

[0087] For each sample time series, inputting the current sample time series into the time series model, and obtaining the prediction result of the homologous water total dissolved solid in the next time window of the current sample time series corresponding time window through the time series model.​

[0088] The function value of the training loss function of the time series model is determined based on the prediction result and the corresponding real value of the total dissolved solids of the homologous water, and the parameters of the time series model are adjusted according to the function value of the training loss function to obtain the total dissolved solids prediction model.

[0089] Specifically, the length of the sliding time window is the second length.

[0090] Optionally, the process of inputting the current sample time series into the time series model to obtain the prediction result of the total dissolved solids of the homologous water in the next time window of the time window corresponding to the current sample time series through the time series model includes: obtaining the first total dissolved solids value of the next time window based on the current sample time series through the time series model.

[0091] Specifically, each total dissolved solids value of the next time window can also be obtained based on the current sample time series.

[0092] Optionally, the process of training the time series model based on the first historical data set to obtain the total dissolved solids prediction model can further include: obtaining a first time series composed of data obtained by performing common processing, such as normalization processing, on the historical data in the first historical data set; and then obtaining the plurality of sample time series by sliding the sliding time window on the first time series.

[0093] Step 1022, determining the current water inlet total dissolved solids value based on the second historical data set through the total dissolved solids prediction model.

[0094] Optionally, the process of determining the current water inlet total dissolved solids value based on the second historical data set through the total dissolved solids prediction model includes: obtaining a to-be-predicted sequence including each historical data in the second historical data set; inputting the to-be-predicted sequence into the total dissolved solids prediction model to predict and output the current water inlet total dissolved solids value through the total dissolved solids prediction model.

[0095] Specifically, the second data set can also be processed, such as normalization processing, to obtain the to-be-predicted sequence.

[0096] The embodiment of the application can establish a total dissolved solids prediction model with higher prediction accuracy for the target water-related equipment, thereby improving the prediction accuracy of the water inlet total dissolved solids of the target water-related equipment.

[0097] The water-related equipment water inlet hardness calculation method provided by the embodiment of the application will be further introduced below, as shown in the following formula (1): Figure 4 As shown in the formula (1), the method can include the following steps:

[0098] At step 401, the historical data of total dissolved solids of incoming water reported by the water intake homologous device is obtained to obtain the homologous water dissolved solid historical data of the target water-related device. The water intake homologous device is another water-related device with the same water source as the target water-related device.

[0099] At step 402, the current total dissolved solids value of the incoming water of the target water-related device is determined based on the homologous water dissolved solid historical data through a time series model.

[0100] At step 403, the sodium ion content of the current incoming water of the target water-related device is obtained based on the ion selective electrode method.

[0101] Specifically, the sodium ion content of the incoming water of the water-related device can be detected in real time through a flow-through electrode probe (such as an insertion type with a diameter of 10-20 mm) directly installed in the water intake pipeline of the water-related device.

[0102] At step 404, the current water hardness of the target water-related device is calculated based on the current total dissolved solids value and the sodium ion content of the current incoming water of the target water-related device.

[0103] It can be understood that the ion selective electrode method determines the concentration through the selective response (based on the Nernst equation) of the electrode membrane to Na + , which is suitable for low to medium salinity water bodies. The embodiment of the present application detects the sodium ion content of the current incoming water based on the ion selective electrode method, which can accurately determine the sodium ion content of the current incoming water of the target water-related device, so as to improve the accuracy of the current water hardness of the target water-related device measured based on the sodium ion content.
