[0097] As a further description of the technical solution of the present invention, the working process of step S4 includes:

[0098] Obtain the current drinking water turbidity, color, temperature and conductivity, and compare them with the standard values ​​set by the system. If any physical parameter exceeds the standard, it can be directly judged as unqualified;

[0109] By the technical solution, the embodiment provides a method for calculating a drinking water physical parameter qualified coefficient based on physical parameters (turbidity, colority, temperature and conductivity). The core principle is to compare the measured value of each parameter with a preset critical value, calculate the score of each parameter, and then obtain a comprehensive qualified coefficient through weighted average, wherein the comprehensive qualified coefficient is calculated by and interval judgment, and the punishment of an over-standard parameter is strengthened, so that the method is applicable to rapid evaluation of water quality in a remote monitoring system, and rapid and quantitative evaluation of the physical safety of drinking water is achieved, thereby providing data support for subsequent purification strategies.

[0110] As a further description of the technical solution of the embodiment, the working process of the step S4 further includes:

[0111] The pH value, dissolved oxygen, residual chlorine, chemical oxygen demand, total organic carbon, heavy metal and nitrate / nitrite of the drinking water at the current time are obtained, and are compared with the standard values set by the system respectively.

[0112] If any chemical parameter is over-standard, the chemical parameter is directly determined as unqualified;

[0113] The mathematical models of the scores of the chemical parameters are respectively constructed, and the expressions are as follows:

[0114]

[0115]

[0116]

[0117]

[0118]

[0119]

[0120]

[0121] ,​​​​​​​​​​​​​​​ 、 、 、 and They are the measured values ​​of drinking water pH, dissolved oxygen, residual chlorine, chemical oxygen demand, total organic carbon, heavy metals and nitrate / nitrite collected at the current moment. 、 、 These are the pH value, dissolved oxygen and residual chlorine reference ranges of drinking water set by the system. 、 、 、 These are the chemical oxygen demand, total organic carbon, heavy metal and nitrate / nitrite thresholds set for the system;

[0122] It should be noted that the measured value of heavy metals refers to the measured value of lead, and the measured value of nitrate / nitrite refers to the comprehensive weighted value.

[0123] Construct a mathematical model of the qualified coefficient of drinking water chemical parameters, the expression is:

[0124] ;

[0125] Where, They are the weight coefficients of drinking water pH, dissolved oxygen, residual chlorine, chemical oxygen demand, total organic carbon, heavy metals and nitrate / nitrite.

[0126] Through the above technical solution, this embodiment provides a method for calculating the qualification coefficient of drinking water chemical parameters based on chemical parameters (pH value, dissolved oxygen, residual chlorine, chemical oxygen demand, total organic carbon, heavy metals, nitrate / nitrite). The core principle is to set the reference range or critical value of each parameter, calculate the score of each parameter, and then obtain the comprehensive chemical safety factor through weighted average. In the formula, The system uses strict interval control and interval judgment to strengthen penalties for exceeding standards. Key parameters such as pH, DO, and residual chlorine are determined using hard intervals to ensure safety. Linear attenuation penalties are applied to COD, TOC, and heavy metals, quantifying the degree of contamination. This system is suitable for rapid water quality assessment in remote monitoring systems, enabling rapid and quantitative evaluation of the physical safety of drinking water and providing data support for subsequent purification strategies.

[0127] As a further description of the technical solution of the present invention, the working process of step S4 also includes:

[0128] Obtain the total coliform group and total bacteria count in drinking water at the current moment, and construct a mathematical model of the qualified coefficient of drinking water biological parameters. The expression is:

[0129] ;

[0130] Where, 、 They are the measured values ​​of total coliform group and total bacteria in drinking water, 、 are the weight coefficients of total coliform group and total bacteria in drinking water, 、 The system presets critical values ​​for total coliform bacteria and total bacteria count in drinking water respectively.

[0131] Through the above technical solution, this embodiment provides a method for calculating the qualification coefficient (B) of drinking water biological parameters based on total coliform (TC) and total bacterial count (HPC). This coefficient is used to assess the microbial safety of drinking water. The core principle is to quantify the microbial contamination risk through a nonlinear mathematical model and combine it with a weighting coefficient to generate a comprehensive score. In this formula, exponential and inverse proportional functions enhance sensitivity to exceedances (high scores at low concentrations and sudden drops when exceedances occur). Through the nonlinear mathematical model and weighting distribution, a rapid quantitative assessment of the microbial safety of drinking water is achieved. Its core advantages include a sudden drop in the score when exceedances occur, avoiding missed detections, highlighting the health risks of coliform bacteria, and being suitable for remote monitoring and rapid detection.

[0132] As a further description of the technical solution of the present invention, the working process of step S4 includes:

[0133] Compare the qualified coefficients of the physical parameters, chemical parameters and biological parameters of drinking water with the threshold intervals corresponding to the qualified coefficients set by the system. If all qualified coefficients meet the corresponding threshold intervals, it means that the drinking water meets the physical, chemical and biological quality requirements;

[0134] If any of the qualified coefficients does not meet the corresponding threshold range, it means that the drinking water does not meet the corresponding quality requirements.

[0135] As a further description of the technical solution of the present invention, the working process of step S4 also includes:

[0136] When all qualified coefficients meet the corresponding threshold ranges, a drinking water score mathematical model is constructed, and the expression is:

[0137]

[0138] Where, 、 and are the weight coefficients corresponding to the physical parameter qualification coefficient, chemical parameter qualification coefficient and biological parameter qualification coefficient, is the score attenuation coefficient, according to 、 and Adjust the size by the difference between the left boundary value of the corresponding threshold interval;

[0139] respectively 、 and Compare the difference between the left boundary value of the corresponding threshold interval and the target value set by the system. If any of them is greater than the target value, =0.7, if not present, =1.

[0140] Compare the drinking water score F with the grade range set by the system and classify the qualified drinking water into grades.

[0141] Through the above technical solution, this embodiment provides a final determination and grading mechanism for drinking water quality. Its core logic is to conduct a comprehensive assessment using the qualification coefficients of three major parameter categories: physical (P), chemical (C), and biological (B), and to grade drinking water based on the score (F). If any of the P, C, and B coefficients does not meet the preset threshold range (), the water quality is directly judged as unqualified without calculating the comprehensive score. If P, C, and B all meet the threshold, the comprehensive scoring process is entered. In the formula, the attenuation coefficient is dynamically adjusted based on the proximity of P, C, and B to the left boundary of their respective thresholds. The physical, chemical, and biological parameters are integrated to avoid misjudgment of a single indicator. The attenuation coefficient enhances the identification of critical risks, realizing intelligent assessment and control of drinking water quality.

[0147] It should be noted that all weight coefficients, thresholds, threshold intervals, and target values ​​in the present invention are empirical values ​​and can be modified based on the characteristics of the type of data to be evaluated.
