BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 A basic flow chart of a method for controlling water quality of a water supply tank provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments.

[0019] Example 1, reference Figure 1 , as an embodiment of the present invention, provides a water supply tank water quality control method, comprising: S1: pre-install a water level detection module, a water quality detection module and a water quality adjustment module inside the water supply tank; S2: Setting a detection cycle, detecting the water quality in the water supply tank based on the detection cycle to obtain water quality data, performing data preprocessing on the water quality data to obtain preprocessed water quality data, recording it as water quality parameters, and calculating the change in the water quality parameters obtained from two adjacent detections; S3: inputting water quality parameters into a pre-built mathematical model, calculating water quality adjustment parameters, and generating corresponding adjustment instructions to adjust the water quality; S4: Calculate the contamination degree of the water supply tank according to the water quality parameters and the change in the water quality parameters. When the preset cleaning conditions are met, issue a cleaning instruction to the staff to clean the water supply tank.

[0020] Specifically, the S1 specifically includes: The water level detection module adopts a liquid level sensor; The water quality detection module is arranged below the lowest water level line inside the water supply tank, and the water quality detection module includes a pH meter, a hardness meter and a biosensor; The water quality regulating module is arranged above the highest water level line inside the water supply tank, and comprises a neutralizer storage unit, a water softener storage unit and an ultraviolet lamp, wherein the neutralizer storage unit comprises an acidic neutralizer storage unit and an alkaline neutralizer storage unit.

[0021] Place the pH meter, hardness meter and biosensor below the lowest water level to avoid the inability to measure water quality data due to the drop in water level. Place the neutralizer storage unit, water softener storage unit and ultraviolet lamp above the highest water level to prevent the water in the water supply tank from touching the stored chemicals.

[0022] Specifically, the S2 specifically includes: Pre-set the inspection cycle, and the staff will judge the difficulty of water storage based on the storage conditions of the water supply tank and historical experience, and set the inspection cycle. The storage conditions of the water supply tank include but are not limited to season, rainfall, human activities, location of the water supply tank and material of the water supply tank; The water quality in the water supply tank is detected based on the detection cycle to obtain water quality data, and the water quality data is preprocessed, wherein the preprocessing includes abnormal data removal and missing data filling, and the preprocessed water quality data is obtained and recorded as water quality parameters; The water quality parameters include water pH, water hardness and microbial concentration in water.

[0023] The difficulty of water storage is determined based on the staff's experience and the storage conditions of the water tank. If it is difficult to store, the detection cycle needs to be shortened. If it is easy to store, the detection cycle needs to be appropriately extended. Under different conditions, the difficulty of water storage is different. For example, when the temperature is low, it is not conducive to the growth of bacteria in the water. At this time, the detection cycle can be appropriately extended. However, the temperature of 15~37°C is conducive to the growth of bacteria, so the detection cycle needs to be shortened.

[0024] Specifically, the mathematical model includes: Determine water quality parameter indicators: Water quality parameter indicators include pH value index, hardness index and microbial concentration index; Establish a standard water quality model: Calculate the standard concentration of various substances in the water according to the water quality parameter indicators, and use the water quality that meets the standard concentration as the standard water quality; Calculate adjustment parameters: According to the current water quality parameters, calculate the concentration of each substance in the current water, and calculate the difference between the concentration of each substance in the current water and the standard concentration of each substance, calculate the current remaining water volume according to the current water level information and the bottom area of ​​the water supply tank, and calculate the water quality adjustment parameters according to the difference and the current remaining water volume.

[0025] According to the current pH value of the water, the concentration of hydrogen ions or hydroxide ions in the water is calculated, and the volume of water is calculated in combination with the current water level information, and then the type and dosage of the required neutralizer are calculated; according to the current hardness of the water, the concentration of calcium ions and magnesium ions is calculated, and the dosage of the required water softener is calculated in combination with the current water level information.

[0026] Specifically, the water quality adjustment parameters include a required neutralizer dosage, a required water softener dosage and a required ultraviolet intensity, and adjustment instructions are respectively issued to the neutralizer storage unit, the water softener storage unit and the ultraviolet lamp based on the water quality adjustment parameters; The adjustment instructions include: the neutralizer storage unit automatically dispenses the neutralizer according to the required neutralizer dosage, the water softener storage unit automatically dispenses the water softener according to the required water softener dosage, and the ultraviolet lamp automatically adjusts the ultraviolet intensity according to the required ultraviolet intensity.

[0027] Specifically, the calculation of the change in water quality parameters between two consecutive tests includes: Obtaining water quality parameters obtained from two consecutive tests, wherein the water quality parameters include pH value of water, hardness of water and concentration of microorganisms in water; Calculate the difference between the pH value of the water detected last time and the pH value detected last time, and record it as the pH value change; The change in water hardness and the change in microbial concentration in the water are calculated using the same calculation logic.

[0028] Controlling water quality does not simply require removing certain substances from the water. After a water supply tank has been used for a period of time, pollutants may accumulate on the inner wall of the tank, causing dirt and causing the water quality to deteriorate quickly. Therefore, this problem can be avoided by determining whether the tank needs to be thoroughly cleaned based on the change in water quality within a testing cycle.

[0029] Specifically, calculating the contamination level of the water supply tank includes: The neutralizer storage unit and the water softener storage unit automatically accumulate the accumulated amount of the neutralizer and the water softener, and the starting accumulation time point is the last cleaning time point of the water supply tank; The degree of contamination of the water supply tank is calculated based on the cumulative amount of the agent, the change in pH value, the change in water hardness and the change in microbial concentration in the water. The calculation formula is:

[0030] in, is the contamination level of the water supply tank, is the weight coefficient, is the cumulative amount of medicine administered, is the pH value change, is the hardness change, is the change in microbial concentration.

[0031] Specifically, when the preset cleaning conditions are met, a cleaning instruction is issued to the staff; The preset cleaning conditions include: the cumulative amount of the administered agent is higher than the first threshold value, or any one of the changes in pH value, water hardness and microbial concentration in the water is higher than the second threshold value, or the contamination degree of the water supply tank is higher than the third threshold value; When any preset cleaning condition is met, a cleaning instruction is issued to the staff to facilitate the staff to clean the water supply tank.

[0032] Neutralizers and water softeners will react with ions in water to generate gas or water-insoluble precipitates. Long-term accumulation may affect the pressure of the water supply tank or cause a large amount of precipitates in the water. Therefore, the total amount of chemicals added is used as a cleaning condition to avoid excessive pressure or excessive precipitation in the water supply tank. When the changes in water quality parameters (pH value, water hardness and microbial concentration) change rapidly, it is considered that the inside of the water supply tank is seriously polluted. The change in water quality parameters is used as a cleaning condition to avoid excessive pollution in the water supply tank.

[0033] The present invention, by constructing a mathematical model, calculates the difference between the current water quality data and the water quality index, and then calculates the adjustment parameters in combination with the current water level information, can specifically adjust the pH value, hardness and concentration of microorganisms in the water supply tank to improve the water quality, and calculates the appropriate cleaning time according to the total amount of the drug added and the change in the water quality parameters, avoiding the impact on the water supply tank caused by excessive drug addition. The method performs targeted adjustments on various substances in the water, improves the targeted control of water quality, and also avoids the waste of human resources caused by too frequent cleaning or the inability to clean in time.

Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment or an embodiment combining software and hardware aspects. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media containing computer-usable program codes. Among them, the storage medium may be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (Static Random Access Memory, referred to as SRAM), electrically erasable programmable read-only memory (Electrically Erasable Programmable Read-Only Memory, referred to as EEPROM), erasable programmable read-only memory (Erasable Programmable Read Only Memory, referred to as EPROM), programmable read-only memory (Programmable Red-Only Memory, referred to as PROM), read-only memory (Read-Only Memory, referred to as ROM), magnetic memory, flash memory, magnetic disk or optical disk.
