[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The water quality pH monitoring method provided in the embodiment of the present application is mainly used in water treatment equipment in home life or office places to monitor the pH value of the water quality of the water treatment equipment.

[0023] Water treatment equipment is a device used to improve water quality, remove impurities from water or adjust water quality, such as a water purifier, a water purifier, etc. The water treatment equipment in the embodiment of the present application is a water purifier with a mineral mineralization function. A water purifier with a mineral mineralization function refers to a type of water purification equipment that can deeply purify tap water and add mineral elements required by the human body to make the water quality reach a standard similar to that of mineral water. After removing harmful substances, the water purifier with a mineral mineralization function reincorporates minerals such as calcium, magnesium, iron, and zinc required by the human body into the water by adding mineral-rich filter materials. These minerals exist in an ionic state and are easier for the human body to absorb.

[0024] The water treatment equipment may include a filter element assembly, a filter, a reverse osmosis device, etc. The filter element assembly in the embodiment of the present application may include one or more alkaline filter materials, which are a filter element or material used for water treatment, and its main function is to convert acidic water into alkaline water, usually by reducing the acidity of water through negative ions, thereby increasing the alkalinity of water.

[0025] One alkaline filter material corresponds to one alkaline water channel. When multiple alkaline filter materials are used, the water channels between the multiple alkaline filter materials are usually set in parallel to ensure that the water flow can pass through each filter material evenly.

[0026] In the embodiments of the present application, the alkaline filter material contains alkaline substances. For a plurality of alkaline filter materials, the types and dissolution rates of the alkaline substances contained in different alkaline filter materials are different. Therefore, the alkaline strengths of different alkaline filter materials are different, thereby achieving different alkaline treatment effects.

[0027] The following uses two alkaline filter materials as an example to illustrate the interaction between alkaline filter materials and their effects in water treatment: For example, in a filter element assembly, the first alkaline filter material is filled with weakly acidic ore, while the second alkaline filter material is filled with ore rich in calcium and magnesium. When the water flows through the first alkaline filter material first, the acidic substances precipitated from the first alkaline filter material can effectively promote the precipitation of calcium and magnesium in the subsequent second alkaline filter material. This promotion effect not only improves the mineralization efficiency, but also makes the water rich in minerals that are beneficial to the human body after passing through the entire filter element assembly.

[0028] For example, in a filter element assembly, the first alkaline filter material is filled with weakly alkaline ore, while the second alkaline filter material is filled with zinc and copper-containing ore. When the water flows through the first alkaline filter material first, the alkaline substances precipitated from the first alkaline filter material will inhibit the precipitation of zinc and copper elements in the second alkaline filter material. This inhibition relationship can control the content of certain minerals in the water.

[0029] For example, in a filter element assembly, the first alkaline filter material contains alkaline minerals of different contents, while the second alkaline filter material contains calcium magnesium minerals of different contents. By adjusting the flow rate of the water flow channel between the first alkaline filter material and the second alkaline filter material, the concentration of different mineralized elements can be flexibly adjusted to meet the specific needs of different users for water quality.

[0030] In the design of the filter element assembly, the arrangement and combination of different filter materials are also crucial. For example, a combination of a surface strong alkaline material (such as brucite) and an inner weak alkaline material (such as calcite) is used. This design allows the filter element to quickly release strong alkaline substances in the early stage, and as the use time goes by, the inner weak alkaline material gradually takes effect, thus ensuring that the filter element can maintain a moderate alkalinity strength throughout its service life.

[0031] By designing and combining different types of alkaline filter materials and their water channel settings, precise mineralization of water quality can be achieved. This not only helps to improve the safety and health of water quality, but also meets the personalized needs of different users for water taste and nutritional value.

[0032] According to the relevant provisions of the "Sanitary Standards for Drinking Water", the normal pH value of drinking water is 6.5-8.5, because a lower pH value is prone to corroding metal water pipes, while a higher pH value causes the calcium and magnesium ions in the water to precipitate and form scale, which has adverse effects on human health.

[0033] In view of the many benefits of alkaline water to human health and the clear provisions of the pH value of water quality in the "Sanitary Standards for Drinking Water", it is particularly important to accurately monitor the pH value of the water quality of water purifiers with mineral mineralization functions. This is not only related to the safety and health of users' drinking water, but also directly affects the stable operation of the equipment and user experience.

[0034] To achieve this goal, the present application embodiment proposes a water quality pH monitoring method for use in water treatment equipment for home life or office. The method aims to ensure that the mineralized water is safe and meets health standards when it reaches the user end by real-time monitoring of the water quality pH value.

[0035] See also Figure 1 As shown, it is a schematic diagram of the process of the water quality pH monitoring method provided in an embodiment of the present application, and the water quality pH monitoring method includes the following steps.

[0036] S11, obtaining a first soluble substance content value upstream of an alkaline filter material and a second soluble substance content value downstream of the alkaline filter material in a water treatment device.

[0037] In the field of water treatment, the soluble substance content value is usually used to measure the total amount of dissolved substances in water, which may include salts, minerals, organic matter, etc. By detecting the soluble substance content value, the quality of water and the effect of water treatment equipment can be evaluated. In the embodiment of the present application, in order to more accurately monitor the water quality pH in the water treatment equipment, the soluble substance content value may include the soluble substance content value or the conductivity.

[0038] The total dissolved solids (TDS) value refers to the total amount of solids dissolved in water, including both inorganic and organic matter. The unit of measurement is mg / L (1mg / L=1ppm), indicating how many milligrams of total dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved matter is contained in the water. Generally, the conductivity value can be used to roughly understand the salt content in the solution. The higher the conductivity, the higher the salt content and the higher the TDS value. A sensor is an instrument that reflects the mineralization degree of water quality by measuring the conductivity of water.

[0039] Conductivity is a measure of the concentration of ions in water, and it reflects the ability of dissolved substances in water to conduct electricity. Dissolved substances in water form ions, which can transmit electric current when moving in water, so conductivity can be used to evaluate the ion concentration in water. The higher the conductivity, the higher the ion concentration in the water, and it may contain more dissolved substances. During the water treatment process, conductivity can be used to monitor changes in water quality and evaluate the effectiveness of water treatment equipment.

[0040] A first sensor may be installed at an appropriate location in the water treatment equipment, for example Figure 2 As shown, a detector 2 is installed at the upstream position of the alkaline filter material of the water treatment equipment to detect the soluble substance content value (i.e., the first soluble substance content value) upstream of the alkaline filter material in real time. The first soluble substance content value is the soluble substance content value before the water flows through the alkaline filter material, that is, the soluble substance content value of the raw water. Similarly, a second sensor can be installed at an appropriate position of the water treatment equipment, for example, Figure 2 As shown, a detector 3 is installed downstream of the alkaline filter material of the water treatment equipment to detect the soluble substance content value (i.e., the second soluble substance content value) downstream of the alkaline filter material in real time. The second soluble substance content value is the soluble substance content value after the water flows through the alkaline filter material.

[0041] S12: Obtain a soluble substance content difference according to the first soluble substance content value and the second soluble substance content value.

[0042] To obtain a soluble matter content difference value, the first soluble matter content value may be subtracted from the second soluble matter content value.

[0043] Assuming that the first sensor is a first TDS sensor, the first TDS sensor detects a first soluble substance content value upstream of the alkaline filter material of TDS 1. The second sensor is the second TDS sensor. The second TDS sensor detects the second soluble substance content value downstream of the alkaline filter material. , then the difference in soluble matter content It can be expressed as: Assuming that the first sensor is a first conductivity sensor, the first conductivity sensor detects a first soluble substance content value of conductivity 1 upstream of the alkaline filter material, and the second sensor is a second conductivity sensor, the second conductivity sensor detects a second soluble substance content value of conductivity 2 downstream of the alkaline filter material, then the soluble substance content difference (Δ conductivity) can be expressed as: .

[0044] The difference in dissolved matter content indicates the change in dissolved matter content in water during the treatment process and can be used to evaluate the performance of water treatment equipment or monitor changes in water quality.

[0045] It should be understood that in water purifiers with mineral spring function, the difference in dissolved matter content is usually not less than 0. The reason is that mineral water purifiers reintegrate the mineral elements needed by the human body into the water by adding mineral-rich filter materials (such as calcium, magnesium, zinc and other ores). These minerals exist in the water in ions or dissolved states. This process will increase the content of dissolved substances in the water. Even though purification treatment is carried out before mineralization to remove harmful substances and impurities in the water, this part of the reduction is mainly non-mineral dissolved solids. The minerals added in the mineralization process will compensate for or even exceed this reduction, causing the overall dissolved matter content value to increase.

[0046] S13, obtaining a target water flow temperature value in the water treatment equipment.

[0047] The water flow temperature in the water treatment equipment is one of the important factors affecting the pH value of water quality. At different temperatures, the degree of water ionization is different, which affects the pH value of the water quality of the water treatment equipment.

[0048] A temperature sensor can be installed at a suitable location in the water treatment equipment, e.g. Figure 2 As shown, a detector 1 is installed upstream of the alkaline filter material of the water treatment equipment to monitor and record the water flow temperature value in the water treatment equipment in real time.

[0049] In actual applications, the water flow temperature in the water treatment equipment may change due to various factors. If the temperature is not corrected, the pH value of the water quality measured at different temperatures may have a large deviation. Therefore, in order to ensure the measurement accuracy of the pH value of the water quality, the real-time water flow temperature in the water treatment equipment must be corrected to obtain the target water flow temperature value.

[0050] In an optional embodiment, the step of obtaining a target water flow temperature value in the water treatment equipment includes: Obtaining a real-time water flow temperature value in the water treatment equipment; Comparing the real-time water flow temperature value with a preset reference temperature value range; When the real-time water flow temperature value is within the preset reference temperature value range, the real-time water flow temperature value is corrected with a preset correction coefficient to obtain the target water flow temperature value; When the real-time water flow temperature value is not within the preset reference temperature value range, the preset correction coefficient is adjusted, and the real-time water flow temperature value is corrected with the adjusted correction coefficient to obtain the target water flow temperature value.

[0051] The preset reference temperature range is set based on experience and the performance of water treatment equipment, the material and characteristics of filter materials, etc., and represents the most suitable water flow temperature range for measuring dissolved matter content. That is, accurate and reliable results can be obtained by measuring dissolved matter content within this reference temperature range.

[0052] The real-time monitored water flow temperature value is compared with the preset reference temperature value range, and whether to adjust the correction coefficient of the temperature value is determined according to the comparison result. When the comparison result shows that the real-time water flow temperature value is within the preset reference temperature value range, the correction coefficient of the temperature value is not adjusted. When the comparison result shows that the real-time water flow temperature value is not within the preset reference temperature value range, the correction coefficient of the temperature value is adjusted.

[0053] When the real-time water flow temperature value is within the preset reference temperature value range, it means that the real-time water flow temperature is within a normal or ideal operating temperature range. Within this range, the preset correction coefficient (which can be a positive constant based on previous experiments or experience, or the preset correction coefficient can also be 0) is considered to be sufficiently accurate and reliable, and can be directly used to correct the real-time water flow temperature value to obtain the target water flow temperature value. At this time, it can be considered that the effect of temperature on pH measurement is controllable and known, so no additional adjustment of the correction coefficient is required. However, when the real-time water flow temperature value is not within the preset reference temperature value range, it means that the real-time water flow temperature deviates from the normal or ideal operating temperature range. In this case, the preset correction coefficient may no longer be accurate or reliable because the change in temperature may cause significant changes in the electrode potential, solution properties, or other factors that affect pH measurement. Therefore, the preset correction coefficient needs to be adjusted to reflect the actual measurement under the current temperature conditions. The adjusted correction coefficient will be used to correct the real-time water flow temperature value to obtain a more accurate target water flow temperature value.

[0054] The above optional implementation method can significantly improve the accuracy of temperature measurement by comparing the real-time water flow temperature value with the preset reference temperature value range, and selecting or adjusting the correction coefficient according to the comparison result, thereby ensuring that the final pH value is based on accurate temperature data. When the real-time water flow temperature value is not within the preset reference temperature value range, the correction coefficient can be automatically adjusted. This adaptive capability enables the system to maintain the accuracy of the measurement results under different temperature conditions, enhancing the robustness and adaptability of the system. And through the automated temperature correction process, the operating process of pH measurement is simplified. The operator can automatically complete these steps without manually adjusting the temperature or correction coefficient, thereby improving work efficiency.

[0055] In an optional implementation, the adjusting the preset correction coefficient includes: Obtaining a temperature deviation degree according to the real-time water flow temperature value and the preset reference temperature value range; The preset correction coefficient is adjusted according to the degree of temperature deviation.

[0056] By calculating the difference or ratio between the real-time water flow temperature value and the center value (or a specific value, such as the upper limit or lower limit) of the preset reference temperature value range, a value indicating the degree of temperature deviation can be obtained. The degree of temperature deviation reflects the difference between the current real-time water flow temperature value and the optimal measurement temperature.

[0057] If the temperature deviation is small, it means that the difference between the real-time water flow temperature value and the center value (or specific value) of the preset reference temperature value range is not large, which means that the current temperature condition is close to the optimal measurement temperature. In this case, it is sufficient to fine-tune the preset correction factor. The fine-tuning range can be relatively small, because the temperature deviation is not large and the impact on the pH measurement is relatively small. By fine-tuning the correction factor, the impact of temperature on the measurement results can be further reduced and the accuracy of the measurement can be improved.

[0058] If the temperature deviation is large, it means that the difference between the real-time water flow temperature value and the center value (or specific value) of the preset reference temperature value range is large, which means that the current temperature condition is far from the optimal measurement temperature. In this case, it is necessary to make a larger adjustment to the preset correction factor. Due to the large temperature deviation, the impact on pH measurement will also be relatively large. Therefore, it is necessary to adjust the correction factor more significantly to compensate for the impact of temperature on the measurement results.

[0059] The above optional implementation method can quantify the influence of temperature on the measurement process by calculating the temperature deviation degree, thereby providing a reliable basis for the subsequent adjustment of the correction coefficient. By appropriately adjusting the preset correction coefficient according to the size, the accuracy of pH measurement can be further improved. For the case where the temperature deviation degree is small, fine-tuning is sufficient; for the case where the temperature deviation degree is large, the correction coefficient needs to be adjusted to a greater extent. The embodiment of the present application adjusts the correction coefficient according to the temperature deviation degree, so that the system can maintain the accuracy of the measurement results under different temperature conditions, thereby enhancing the adaptability and robustness of the system.

[0060] In an optional implementation, the adjusting the preset correction coefficient according to the temperature deviation degree includes: Obtaining a temperature deviation severity according to the temperature deviation degree and a preset temperature deviation degree threshold; Determining a water flow velocity value of the alkaline filter material; Obtaining a correction adjustment coefficient according to the water flow velocity value and the severity of the temperature deviation; The preset correction coefficient is adjusted according to the correction adjustment coefficient.

[0061] Water flow velocity refers to the displacement of water flow per unit time, usually in meters per second (m / s). A first water flow velocity sensor or flow meter can be set upstream of the alkaline filter material, and the first water flow velocity sensor or flow meter is used to detect the water flow velocity upstream of the alkaline filter material (i.e., the first water flow velocity). The first water flow velocity indicates the speed of the water flow before passing through the alkaline filter material, reflecting the flow state of the water before entering the filter material. A second water flow velocity sensor or flow meter can also be set downstream of the alkaline filter material, and the second water flow velocity sensor or flow meter is used to detect the water flow velocity downstream of the alkaline filter material (i.e., the second water flow velocity). The second water flow velocity indicates the speed of the water flow after passing through the alkaline filter material, reflecting the flow state of the water after being treated by the filter material. The water flow velocity value of the alkaline filter material can be either the first water flow velocity or the second water flow velocity.

[0062] The difference or ratio between the temperature deviation degree and a preset temperature deviation degree threshold value can be calculated to obtain the temperature deviation severity. The temperature deviation severity reflects the difference between the current temperature condition and the optimal measurement temperature.

[0063] An increase in water velocity increases the convective heat transfer coefficient, which affects the efficiency of heat exchange between the water flow and the surrounding environment (such as the water pipe wall, other components in the water treatment equipment, etc.). This heat exchange affects the temperature distribution of the water flow, which in turn may affect the accuracy of the temperature measurement. Therefore, when considering temperature correction, the effect of water flow velocity on temperature distribution and measurement must be considered. Combining the water flow velocity value and the severity of temperature deviation, a correction adjustment factor can be calculated, and the preset correction factor can be adjusted based on the calculated correction adjustment factor.

[0064] The correction adjustment coefficient can be calculated according to the following formula: ; Where Kf is the correction adjustment coefficient, α and β It is a weight coefficient used to adjust the influence of the water velocity value RV and the temperature deviation severity ΔT / T0 on the correction coefficient. ΔT represents the temperature deviation degree, and T0 represents the preset temperature deviation degree threshold.

[0065] Indicates the relative magnitude of temperature deviation. This value is a dimensionless ratio that measures the severity of temperature deviation.

[0066] The influence of water velocity value and temperature deviation on the correction coefficient is combined. By adjusting the values ​​of α and β, the influence of these two factors on the correction adjustment coefficient can be changed.

[0067] The above optional implementation method, by obtaining the water flow velocity value, helps to more accurately evaluate the impact of the water flow state on the temperature measurement, thereby making a more reasonable correction factor adjustment decision. The calculation of the severity of temperature deviation helps to more accurately understand the impact of the current environmental conditions on the measurement process, and provide more targeted guidance for the subsequent adjustment of the correction factor.

[0068] S14, calculating based on the soluble substance content difference and the target water flow temperature value to obtain the water quality pH value.

[0069] The water quality pH value can be calculated based on the target water flow temperature value and the soluble substance content difference according to the first target mapping relationship. The first target mapping relationship is used to characterize the corresponding relationship between the target water flow temperature value, the soluble substance content difference and the water quality pH value.

[0070] In order to obtain the first target mapping relationship, it is necessary to collect water quality sample data from different water sources and water flow temperatures in advance, and fit the possible correlation or functional relationship between the target water flow temperature value, the difference in soluble substance content and the pH value based on the water quality sample data, and then use the fitted correlation or functional relationship to calculate the water quality pH value based on the target water flow temperature value and the difference in soluble substance content.

[0071] Water quality sample data can include target water flow temperature value, soluble matter content difference and corresponding pH value. Collecting water quality sample data from different water sources and water flow temperatures is to ensure that the functional relationship fitted based on the water quality sample data has sufficient generalization ability. Water quality conditions are dynamically changing and are affected by many factors. By collecting diverse water quality sample data, it can be ensured that the model can learn the complex relationship between different water quality characteristics to better adapt to the trend of water quality parameters changing over time and space, thereby providing more reliable prediction results.

[0072] The collected water quality sample data are preprocessed, including removing outliers and data smoothing, to improve data quality.

[0073] Use appropriate data fitting methods (such as linear regression, polynomial regression, machine learning algorithms, etc.) to fit the relationship between the target water flow temperature value, the difference in dissolved matter content, and the pH value, so as to find a mathematical function that can best describe the relationship between the two. For example, the target water flow temperature value T, the difference in dissolved matter content, such as ( ) and pH value are linearly fitted to obtain the relationship: .

[0074] Among them, a is the source term constant, b is the amplitude index, and c is the temperature correction coefficient. All three are related to the alkalinity of mineralized filter materials and are measured experimentally.

[0075] As the temperature rises, the degree of ionization of water increases, and the number of ionized hydrogen ions and hydroxide ions increases at the same time. At the same time, it will affect the solubility of minerals and salts dissolved in water. The solubility of some minerals and salts increases when the water temperature rises, and the solubility decreases when the water temperature decreases. Therefore, the difference in upstream and downstream water flow temperatures may cause changes in the amount of minerals and salts dissolved in water, thereby affecting the upstream and downstream soluble substance content values ​​(TDS values ​​or conductivity). In an embodiment of the present application, obtaining the target water flow temperature value in the water treatment equipment includes obtaining a first target water flow temperature value upstream of the alkaline filter material and a second target water flow temperature value downstream of the alkaline filter material.

[0076] A first temperature sensor may be arranged upstream of the alkaline filter material, and the first temperature sensor is used to detect the real-time water flow temperature value upstream of the alkaline filter material, and correct the real-time water flow temperature value upstream to obtain a first target water flow temperature value. Similarly, a second temperature sensor may be arranged downstream of the alkaline filter material, and the second temperature sensor is used to detect the real-time water flow temperature value downstream of the alkaline filter material, and correct the real-time water flow temperature value downstream to obtain a second target water flow temperature value.

[0077] In an optional embodiment, the calculation based on the soluble substance content difference and the target water flow temperature value to obtain the water quality pH value includes: The pH value of the water quality is obtained by calculation based on the difference in the content of soluble substances, the first target water flow temperature value and the second target water flow temperature value.

[0078] The water quality pH value can be calculated based on the first target water flow temperature value, the second target water flow temperature value and the difference in dissolved substance content according to the second target mapping relationship. The second target mapping relationship is used to characterize the correspondence between the first target water flow temperature value, the second target water flow temperature value, the difference in dissolved substance content and the water quality pH value.

[0079] In order to obtain the second target mapping relationship, it is necessary to collect water quality sample data from different water sources and conditions in advance, and fit the possible correlation or functional relationship between the first target water flow temperature value, the second target water flow temperature value, the difference in soluble substance content and the pH value based on the water quality sample data, and then use the fitted correlation or functional relationship to calculate the water quality pH value based on the first target water flow temperature value, the second target water flow temperature value and the difference in soluble substance content.

[0080] The water quality sample data may include the first target water flow temperature value, the second target water flow temperature value, the difference in dissolved matter content and the corresponding pH value. Collecting water quality sample data from different water sources and conditions is to ensure that the functional relationship fitted based on the water quality sample data has sufficient generalization ability. Water quality conditions are dynamically changing and are affected by many factors. By collecting diverse water quality sample data, it can be ensured that the model can learn the complex relationship between different water quality characteristics to better adapt to the trend of water quality parameters changing over time and space, thereby providing more reliable prediction results.

[0081] The collected water quality sample data are preprocessed, including removing outliers and data smoothing, to improve data quality.

[0082] Use appropriate data fitting methods (such as linear regression, polynomial regression, machine learning algorithms, etc.) to fit the relationship between the first target water flow temperature value, the second target water flow temperature value, the difference in dissolved matter content and the pH value, so as to find a mathematical function that can best describe the relationship between the four.

[0083] The above optional implementation, if only the difference in soluble substance content and the first target water flow temperature value are considered, may result in errors due to ignoring temperature changes. By introducing the second target water flow temperature value, this error can be better corrected, and the impact of temperature changes of the water flow during the entire treatment process on the pH value can be more comprehensively considered. It helps to more accurately reflect the water quality conditions and improve the accuracy of the calculation results. In addition, the introduction of the second target water flow temperature value when calculating the water quality pH value can achieve more real-time monitoring and early warning functions. When the water flow temperature changes abnormally, the problem can be discovered in time and corresponding treatment measures can be taken to ensure water quality safety.

[0084] In another optional embodiment, the calculation based on the soluble substance content difference and the target water flow temperature value to obtain the water quality pH value includes: Obtaining a water flow temperature difference based on the first target water flow temperature value and the second target water flow temperature value; The pH value of the water quality is obtained by calculation based on the difference in the content of soluble substances and the difference in the water flow temperature.

[0085] The water quality pH value can be calculated based on the water flow temperature difference and the soluble substance content difference according to the third target mapping relationship. The third target mapping relationship is used to characterize the corresponding relationship between the water flow temperature difference, the soluble substance content difference and the water quality pH value.

[0086] In order to obtain the third target mapping relationship, it is necessary to collect water quality sample data from different water sources and conditions in advance, and fit the possible correlation or functional relationship between the water flow temperature difference, the soluble substance content difference and the pH value based on the water quality sample data, and then use the fitted correlation or functional relationship to calculate the water quality pH value based on the water flow temperature difference and the soluble substance content difference.

[0087] Water quality sample data can include the difference in water flow temperature and the difference in dissolved matter content and the corresponding pH value. Collecting water quality sample data from different water sources and conditions is to ensure that the functional relationship fitted based on the water quality sample data has sufficient generalization ability. Water quality conditions are dynamically changing and are affected by many factors. By collecting diverse water quality sample data, it can be ensured that the model can learn the complex relationship between different water quality characteristics to better adapt to the trend of water quality parameters changing over time and space, thereby providing more reliable prediction results.

[0088] The collected water quality sample data are preprocessed, including removing outliers and data smoothing, to improve data quality.

[0089] Use appropriate data fitting methods (such as linear regression, polynomial regression, machine learning algorithms, etc.) to fit the relationship between the water temperature difference, the dissolved matter content difference and the pH value, so as to find a mathematical function that can best describe the relationship between the three.

[0090] In summary, the solutions for obtaining the pH value of water quality in this application include the following three methods: Solution 1: Calculate the pH value of water quality based on the difference in dissolved matter content and the first target water flow temperature value.

[0091] Solution 2: Calculate the pH value of water quality based on the difference in dissolved matter content, the first target water flow temperature value and the second target water flow temperature value.

[0092] Solution 3: Calculate the pH value of water quality based on the difference in dissolved matter content and the difference in water flow temperature (the difference between the first target water flow temperature value and the second target water flow temperature value).

[0093] The above scheme 1 only considers the difference in dissolved matter content and the first target water flow temperature value, but ignores the temperature change of the water flow during the treatment process, which may affect the accuracy of the pH value. The third scheme introduces the water flow temperature difference to more comprehensively consider the temperature change of the water flow during the entire treatment process, thereby improving the accuracy of the pH value calculation.

[0094] Although the above-mentioned scheme 2 takes into account the first target water flow temperature value and the second target water flow temperature value, it does not explicitly use the difference between the two to directly reflect the change in water flow temperature. The third scheme explicitly uses the water flow temperature difference, which more directly reflects the temperature change of the water flow during the treatment process, thereby improving the accuracy of the pH value calculation. In scheme 2, it is necessary to consider the first target water flow temperature value and the second target water flow temperature value at the same time, and it is necessary to establish a complex model containing two temperature variables to calculate the pH value. In the third scheme, since the water flow temperature difference has been calculated, the calculation process can be simplified, and only a model containing the water flow temperature difference and the soluble matter content difference needs to be established. Using the water flow temperature difference as an input variable of the model can make the model easier to understand and explain. Because the water flow temperature difference directly reflects the temperature change of the water flow during the treatment process, the impact of this change on the pH value is obvious.

[0095] In an optional embodiment, the method further comprises: The water quality pH value is displayed using a preset display method.

[0096] After the pH value of the water is monitored, the pH value is saved in real time for subsequent analysis of the water quality and state. At the same time, the pH value of the water is displayed on the display interface at the end of the water path, so that people can intuitively understand whether the water quality in the water treatment equipment is more suitable for drinking.

[0097] The preset display modes may include one or a combination of the following: color coding, chart display, digital display, etc.

[0098] Color coding is based on the range of water pH values, using different colors for coding. For example, green indicates good water quality (pH value close to neutral), yellow indicates average water quality (pH value slightly deviates from neutral), and red indicates poor water quality (PH value deviates greatly from neutral). This color coding method can intuitively reflect the water quality status and facilitate users to quickly judge.

[0099] The chart display shows the changing trend of water quality pH value through bar charts, line charts, etc. These charts can clearly show the changes of water quality pH value over time, space and other factors, which helps users find potential problems or patterns.

[0100] Digital display directly displays the pH value of water quality on the display screen. This method can provide accurate data information, which is convenient for users to conduct quantitative analysis and comparison.

[0101] At the same time, digital display can also be combined with color coding, chart display, color bars or lights to form a more comprehensive information display method.

[0102] In actual applications, the preset display mode can be flexibly adjusted according to user needs, application scenarios and other factors.

[0103] The above optional implementation method can improve user experience and enhance data readability by visually displaying the pH value of water quality after monitoring. In an optional embodiment, the method further comprises: Comparing the water quality pH value with a preset water quality pH threshold range; When the water quality pH value exceeds the preset water quality pH threshold range, an alarm is issued according to a preset alarm method.

[0104] The preset water quality pH threshold range is usually determined based on water quality standards, industry standards or the requirements of a specific application scenario. Optionally, the preset water quality pH threshold range is 6.5 to 8.5.

[0105] The real-time monitored water quality PH value is compared with the preset water quality PH threshold range. If the water quality PH value falls within the preset water quality PH threshold range, it indicates that the water quality is within the normal or ideal pH range and the water quality meets the standard; if the water quality PH value exceeds the preset water quality PH threshold range, for example, PH<6.5 or PH>8.5, it indicates that the water quality does not meet the standard.

[0106] When the pH value of the water flowing out of the water treatment equipment exceeds the preset water quality pH threshold range, sometimes the user cannot find it in the first time. Therefore, the water treatment equipment in the embodiment of the present application is also equipped with an audio-visual alarm module, which is electrically connected to the central processing module and is uniformly controlled and executed by the central processing module. The alarm prompt can be made by sound and / or light. This prompt method can attract the user's attention and take timely measures to solve the water quality problem. Alarm content: The alarm content should include real-time data of the water quality pH value, specific circumstances exceeding the threshold (such as exceeding the upper or lower limit), possible hazards, and recommended countermeasures. This information helps users or relevant personnel quickly understand water quality problems and take corresponding treatment measures.

[0107] Alarm prompts can also be given by SMS notification, email notification, etc. Different alarm methods can be selected according to different application scenarios and user needs.

[0108] The above optional implementation method compares the water quality pH value with the preset water quality pH threshold range and takes corresponding alarm measures based on the comparison results, which not only improves the automation and efficiency of water quality monitoring and reduces human intervention and errors; it also ensures that an alarm can be issued in time when the water quality does not meet the standards, thereby effectively preventing potential environmental and health risks.

[0109] The water quality pH monitoring method provided in the embodiment of the present application provides a direct basis for the subsequent pH value calculation by directly obtaining the first soluble substance content value upstream of the alkaline filter material and the second soluble substance content value downstream in the water treatment equipment. The soluble substance content difference is calculated based on the second soluble substance content value and the first soluble substance content value. The soluble substance content difference represents the amount of change in the soluble substance content of the water quality during the treatment process and can be used to monitor the change in water quality. Since the temperature of water affects its degree of ionization and the activity of dissolved substances, thereby affecting the pH value, the present application can more accurately reflect the changes in water quality by comprehensively considering the two key factors of water flow temperature and soluble substance content difference, thereby improving the accuracy and reliability of pH value calculation. In addition, the present application avoids the use of expensive pH meters and reduces the cost of water quality monitoring.

[0110] By real-time monitoring of the pH value of water quality, problems existing in the operation of water treatment equipment, such as aging of filter materials, insufficient chemical reactions, etc., can be discovered in a timely manner, so that timely adjustments and optimizations can be made to improve the operating efficiency and service life of the equipment.
