[0002] The use of water supply devices is becoming more and more common. Water supply devices are widely used in homes, businesses and public places to provide convenient drinking water supply. However, water supply devices often face water pollution problems during daily use. For example, the growth of microorganisms, the reproduction of bacteria and the accumulation of other harmful substances may cause water quality deterioration and affect the health of residents.

[0003] The sterilization methods of existing water supply devices mainly rely on manual monitoring and regular maintenance, and usually lack automated and intelligent water quality monitoring and sterilization mechanisms. Users often cannot grasp the changes in water quality parameters in real time, and it is difficult to adjust sterilization measures in time according to the actual water quality conditions. This passive management method not only increases water quality risks, but may also lead to unnecessary waste of resources.

[0004] There are already some smart water supply devices with sterilization functions on the market, but most devices still have limitations in setting sterilization parameters, making it difficult to flexibly adjust for different water quality conditions. In addition, existing water quality monitoring technologies generally cannot achieve high-frequency real-time data acquisition, which often leads to detection lags, thus affecting the sterilization effect. Summary of the invention

[0005] Based on this, it is necessary to address the sterilization problem of existing water supply devices and propose a sterilization method for water supply devices.

[0074] like Figure 5 As shown, in one embodiment, a method for sterilizing a water supply device is provided. The method can be applied to both a terminal and a server. This embodiment is illustrated by applying the method to a terminal. The method for sterilizing a water supply device specifically includes the following steps:

[0075] S1: Obtain water quality parameters in real time according to the preset interval time;

[0076] S2: Determine whether the sterilization signal is triggered;

[0077] S3: when the sterilization signal is triggered, obtaining the current state information of the object to be sterilized in the water supply device; wherein the current state information includes the water quality parameters of the object to be sterilized at a preset number of time points before the current time;

[0078] S4: Based on the correspondence between the preset state information and the sterilization parameters, setting the target sterilization parameters corresponding to the current state information;

[0079] S5: Sterilize the object to be sterilized based on the target sterilization parameters.

[0080] As described in step S1 above, water quality parameters are obtained in real time at preset intervals. The step of obtaining water quality parameters can be to monitor water quality in real time using various sensors (such as temperature sensors, turbidity sensors, conductivity sensors, pH sensors, etc.), and can also be measured by optical methods, such as optical principles such as light transmission and reflection, such as turbidity, color, dissolved oxygen and other parameters of water.

[0081] As described in step S2 above, determine whether the sterilization signal is triggered. The condition for triggering the sterilization signal may be manual input by the user. A user interface (UI) or control panel may be provided to allow the operator to manually input the sterilization signal. The user may also input the sterilization signal through a corresponding APP. In some embodiments, the sterilization signal may be automatically triggered when the water quality parameter exceeds the normal range.

[0082] As described in the above step S3, when the sterilization signal is triggered, the current state information of the object to be sterilized of the water supply device is obtained; wherein, the current state information includes the water quality parameters of the object to be sterilized at a preset number of time points before the current time. The number of time points to be traced back is set according to specific needs, such as "3 time points" or "5 time points". The previous water quality parameters will be stored in the corresponding database, and can be directly obtained here, and the obtained data will be integrated into a structured state information object, that is, the current state information, so as to facilitate the subsequent execution of the corresponding sterilization process based on the current state information.

[0083] As described in step S4 above, based on the correspondence between the preset state information and the sterilization parameters, the target sterilization parameters corresponding to the current state information are set. Based on historical data and laboratory research, target sterilization parameters for different water quality states are set. For example: when the turbidity is higher than a specific value, increase the sterilization time or increase the sterilization intensity (such as UV intensity or ozone concentration). When the pH value is lower or higher than the optimal range, adjust the corresponding amount of chemical sterilizer. The corresponding relationship is a pre-set relationship. After obtaining the current state information, the corresponding sterilization parameters can be obtained.

[0084] As described in step S5 above, the object to be sterilized is sterilized based on the target sterilization parameters. Specifically, the sterilization parameters may include sterilization intensity, time, sterilization dosage used, etc. Then, according to the target sterilization parameters, the corresponding sterilization equipment is started: for example, ultraviolet sterilization can set the ultraviolet intensity and sterilization time. Ozone sterilization can adjust the output of the ozone generator and the sterilization duration. Hot water sterilization can set the heating temperature and holding time. By acquiring water quality parameters in real time, the system can quickly determine whether the water quality is abnormal, trigger the sterilization signal in time, reduce the risk of water pollution, and flexibly adjust the target sterilization parameters according to historical data and real-time water quality status to ensure the effectiveness of the sterilization operation, while avoiding unnecessary over-sterilization, significantly improving the efficiency, safety and economy of the water quality management system, and providing a modern solution for the water treatment industry, while also bringing greater convenience and trust to users. The object to be sterilized can specifically be Figure 4 The hot tank 302 or the refrigeration unit 20 in the refrigeration unit 20, the refrigeration unit 20 can specifically be a cold tank.

[0085] In one embodiment, before the step S4 of setting the target sterilization parameter corresponding to the current state information based on the preset correspondence between the state information and the sterilization parameter, the method further includes:

[0086] S301: Acquire multiple historical status information;

[0087] S302: Calculate the water quality vector X of each historical state information i ={(Q t，t-1 ), (Q t，t-2 ),...,(Q t，z )..., (Q t，2 ), (Q t，1 )}, where t represents the tth time point, X i The water quality vector representing the i-th historical state information, (Q t，z ) represents the rate of change of water quality parameters between the t-th time point and the z-th time point, t, z, i are positive integers, and t>z, i≤n;

[0088] S303: performing standardization processing on each of the water quality vectors according to a preset method to obtain a standard data set;

[0089] S304: Input the standard data set and the sterilization parameters corresponding to the standard data set into a preset model, train the preset model according to the optimal hyperparameter method, and obtain a target model to achieve a corresponding relationship between the construction state information and the sterilization parameters.

[0090] As described in the above step S301, a plurality of historical status information is obtained, wherein the historical status information is the same as the above current status information, that is, previous status information, and can be obtained by obtaining it from a corresponding database.

[0091] As described in step S302 above, the water quality vector of each of the historical state information is calculated. The water quality vector at each time point is defined to be related to the water quality vector at the previous time point, that is, the change of the water quality parameters can be detected. If the water quality parameters change rapidly, it means that the corresponding bacterial colony reproduces rapidly, so it is necessary to increase the sterilization intensity, so that the change rate of the water quality parameters between the t-th time point and the z-th time point is used as the value in the water quality vector for subsequent calculations.

[0092] As described in step S303 above, each of the water quality vectors is standardized according to a preset method to obtain a standard data set. The standardized processing may be dimensionality reduction, denoising, and removal of unnecessary data, etc. The preset method may be to process the data using a sliding window, or to reduce the dimensionality of the data, transform the data, etc. A preferred standardized processing method is provided later, which will not be described here.

[0093] As described in step S304 above, the standard data set and the sterilization parameters corresponding to the standard data set are input into the preset model, and the preset model is trained according to the optimal hyperparameter method to obtain the target model to achieve the corresponding relationship between the state information and the sterilization parameters. Among them, the preset model is an SVM model or an ANN model, wherein SVM (support vector machine) is one of the most popular machine learning technologies and an approximate representation of structural risk minimization. It seeks the best combination point between the generalization performance and the fitting performance of the model, rather than the traditional empirical risk minimization, and cleverly solves the dimensionality problem, and can process the standardized data. Its training method is the same as the existing model training method, which will not be repeated here.

[0094] In one embodiment, the step S304 of inputting the standard data set and the sterilization parameters corresponding to the standard data set into a preset model, training the preset model according to the optimal hyperparameter method, and obtaining a target model to implement the corresponding relationship between the state information and the sterilization parameters includes:

[0095] S3041: Obtaining initial models of multiple different hyperparameter combinations;

[0096] S3042: Dividing the standard data set into a training set and a validation set according to a preset ratio;

[0097] S3043: inputting the training set and the corresponding sterilization parameters into each of the initial models for training to obtain a corresponding plurality of temporary models;

[0098] S3044: verifying each of the temporary models using the verification set to obtain verification results of each of the temporary models;

[0099] S3045: Based on the verification results, the temporary model with the best verification results is selected as the preset model.

[0100] As described in the above steps S3041-S3045, if the preset model is an SVM model, since its generalization ability depends on the original parameters, multiple different hyperparameter combinations can be set for joint training, and then the optimal model is selected for processing. First, multiple different initial SVM models are created by selecting multiple sets of hyperparameters (such as penalty parameter C, kernel function type, γ value, etc.). The standard data set is divided into a training set and a validation set, usually using a ratio of 70% training set and 30% validation set, or other reasonable ratios. The selected training set and its corresponding sterilization parameters are input into the previously created initial SVM model for training, and finally multiple temporary models are obtained. Each model will learn a specific pattern according to different hyperparameter combinations, capture the features in the training data, and use the validation set to evaluate each temporary model. Usually, some performance indicators (such as accuracy, precision, recall rate, F1 score, etc.) are used to measure the effectiveness of the model, compare the performance of each temporary model on the validation set, and select the model with the best performance as the final preset model. It can effectively build and select suitable machine learning models to meet specific water quality monitoring and sterilization parameter prediction business needs.

[0101] In one embodiment, the step S303 of performing standardization processing on each of the water quality vectors according to a preset method to obtain a standard data set includes:

[0102] S3031: extracting the maximum value point and the minimum value point in each of the water quality vectors, and arranging them in chronological order to obtain an extreme value sequence;

[0103] S3032: Fit the extreme value sequence using a cubic spline interpolation function to obtain an upper envelope X max (t) and the lower envelope X min (t);

[0104] S3033: Take the average of the upper envelope and the lower envelope as the envelope average m(t); where,

[0105] S3034: Subtract the envelope mean from the water quality vector to obtain a target sequence;

[0106] S3035: Determine whether the target sequence passes the intrinsic mode function test;

[0107] S3036: If the test is passed, the target sequence is recorded as the target function; otherwise, the target sequence is recorded as the first water quality vector and the target sequence is recalculated until the target function is obtained;

[0108] S3037: subtract the first water quality vector from the water quality vector to obtain a second water quality vector, and repeat to obtain multiple objective functions until the calculated envelope is symmetrical and the mean of the envelope is 0, thereby obtaining multiple objective functions;

[0109] S3038: Aggregate the objective functions of each water quality vector to obtain standard data corresponding to each water quality vector, and then obtain a standard data set composed of the various standard data.

[0110] As described in the above steps S3031-S3038, in order to improve the judgment ability of the model, the implicit features can be extracted. In order to improve the judgment ability of the model, the implicit features can be extracted. The specific steps are: decompose the feature vector, extract the minimum and maximum points in each feature vector, and arrange them in chronological order to form an extreme value sequence. The extreme value sequence is fitted using a cubic spline interpolation function to obtain the upper and lower envelopes. The mean of the upper and lower envelopes is recorded as the envelope mean. The envelope mean is subtracted from the feature vector to obtain the target sequence. If the target sequence does not pass the intrinsic mode function test, it is recorded as the first feature vector and the target sequence is recalculated until the target function is generated; if it passes the test, the target sequence is recorded as the target function, and the target function set of each feature vector is formed to form the standard data corresponding to each feature vector, and further construct a standard data set composed of each standard data. Among them, the intrinsic mode function is a pre-set function, which can be set manually as needed. By decomposing the feature vector as above, the prediction performance of the machine learning model can be improved. Cubic spline interpolation is achieved by solving a series of shape value points for a smooth curve. Mathematically, it is a process of deriving a curve function group through a group of three bending moment equations.

[0111] In one embodiment, after the step S5 of sterilizing the object to be sterilized based on the target sterilization parameters, the method further includes:

[0112] S601: Detect target water quality parameters after sterilization;

[0113] S602: Determine whether the water quality parameter meets the preset standard;

[0114] S603: If the preset standard is not reached, the object to be sterilized is sterilized for a second time based on the target water quality parameter.

[0115] As described in the above steps S601-S603, after completing the first round of sterilization operation, the water quality parameters of the body to be sterilized are monitored and obtained in real time. These parameters may include key information such as turbidity, pH value, bacterial concentration, dissolved oxygen, etc. The purpose is to confirm the effect of the sterilization operation and provide a basis for subsequent judgment of whether the water quality meets the standard. Determine whether the water quality parameters meet the preset standards, and compare the detected water quality parameters with the pre-set water quality standards. The preset standards are usually based on national or regional drinking water safety standards or other industry standards. The purpose is to evaluate whether the water quality after sterilization meets the prescribed safety standards and ensure its suitability for use. If the preset standards are not met, the body to be sterilized is sterilized for the second time based on the target water quality parameters. If the detected water quality parameters fail to meet the preset standards, the second sterilization is performed again according to the target water quality parameters. In this process, it may be necessary to adjust the sterilization parameters (such as intensity, time or sterilization dose used) to ensure the effect. Through the secondary sterilization operation, the water quality is further improved to ensure that the safety standards are met.

[0116] In one embodiment, after the step S1 of acquiring water quality parameters in real time at a preset interval, the method further includes:

[0117] S201: Determine whether at least one of the water quality parameters exceeds a preset parameter value;

[0118] S202: If at least one of the parameters exceeds the preset parameter value, water in the object to be sterilized is extracted and discharged through a preset water pump.

[0119] As described in step S201 above, it is determined whether at least one of the water quality parameters exceeds the preset parameter value. Each water quality parameter (such as turbidity, pH value, temperature, bacteria concentration, etc.) is monitored in real time and compared with the preset parameter value. Potential water quality problems can be discovered in time to ensure that the water quality is within a safe range. If any parameter is found to exceed the set safety threshold, the subsequent processing steps are triggered.

[0120] As described in step S202 above, if at least one of the preset parameter values ​​is exceeded, the water in the sterilized body is extracted and discharged through the preset water pump. Once the water quality parameter is confirmed to be abnormal, the system starts the preset water pump to extract water from the sterilized body and discharge it, which may be discharged into the sewage treatment system or other safe discharge areas. By excluding contaminated water, the potential impact of unqualified water on subsequent processing and distribution is reduced, and water quality problems are controlled at the source. Among them, the preset water pump is the water pump connected to the sterilized body, refer to Figure 4 If the object to be sterilized is a hot tank 302 , the preset water pump is the first water pump 150 ; if the object to be sterilized is a refrigeration unit 20 , the preset water pump is the second water pump 100 .

[0121] In one embodiment, before the step S5 of sterilizing the object to be sterilized based on the target sterilization parameters, the method further includes:

[0122] S401: Determine whether the current water quality parameters meet the drinking standards;

[0123] S402: If the current water quality parameters meet the drinking standard, the user's historical sterilization time period is obtained;

[0124] S403: Acquire the current time, and select the sterilization time according to the user's historical sterilization time period and the current time.

[0125] As described in step S401 above, it is determined whether the current water quality parameters meet the drinking water standards, and the current water quality parameters are evaluated and compared with the drinking water standards, including turbidity, pH value, bacteria concentration, etc. This ensures that the water quality meets the drinking water standards before performing the sterilization operation, avoiding sterilization under the condition that the water quality does not meet the standards, resulting in ineffective treatment or user health risks.

[0126] As described in step S402 above, if the current water quality parameters meet the drinking standard, the user's historical sterilization time period is obtained. If the current water quality meets the standard, the system will query and obtain the user's historical sterilization time period. These time periods may be time periods when the user previously performed effective sterilization operations. User behavior can be analyzed to consider the user's usage patterns and needs in the sterilization strategy, enhancing the personalization and adaptability of the system.
