[0006] The filter element status analysis module is used to perform comprehensive calculation and analysis on the water purification status parameters of the water purification system in each operating period, and obtain the water purification filter element status parameters of the water purification system in each operating period. The specific calculation and analysis method is as follows:

[0007] The water inlet pressure, outlet pressure, inlet flow rate and outlet flow rate of the water purification system corresponding to each operating period are obtained from the water purification state parameters of the water purification system corresponding to each operating period, and the water inlet pressure, outlet pressure, inlet flow rate and outlet flow rate of the water purification system corresponding to each operating period are obtained, which are recorded as IP i OP i , IQ i and OQ i, i represents the number of each operating period, i = 1, 2, ..., n, n represents the total number of each operating period, the water inlet pressure and water outlet pressure of the water purification system corresponding to each operating period are calculated by difference, and the water inlet pressure difference of the water purification system corresponding to each operating period is obtained, which is recorded as ΔXP i , the difference between the inlet flow rate and the outlet flow rate of the water purification system corresponding to each operating period is calculated to obtain the inlet flow difference of the water purification system corresponding to each operating period, which is recorded as ΔXQ i ;

[0008] Substitute the above data into the calculation formula Calculate the pressure-flow state coefficient S of the water purification system corresponding to each operating period 1i , where α represents the set weight factor, 0<α<1, which is used to adjust the proportion of the pressure difference and flow difference of the water body in the pressure-flow state coefficient;

[0010] Substitute the above data into the calculation formula Calculate the filter element status coefficient S of the water purification system corresponding to each operating period 2i ;

[0011] The water purification state parameters of the water purification system corresponding to each operating period are jointly composed of the pressure flow state coefficient and the filter element state coefficient of the water purification system corresponding to each operating period;

[0012] The physical property analysis module is used to perform comprehensive calculation and analysis on the water body physical parameters corresponding to each operation period of the water purification system, and obtain the water body physical purification state coefficient corresponding to each operation period of the water purification system;

[0013] The chemical property analysis module is used to perform comprehensive calculation and analysis on the water chemical parameters of the water purification system corresponding to each operating period, and obtain the water chemical purification state coefficient of the water purification system corresponding to each operating period;

[0014] A fault warning evaluation module is used to evaluate and analyze the water purification state parameters, water physical purification state coefficients, and water chemical purification state coefficients of the water purification system corresponding to each operating period, and generate fault warning signals of the water purification system corresponding to each operating period;

[0015] Control terminal, based on the fault warning signals of the water purification system corresponding to each operating period, arrange personnel to conduct troubleshooting and maintenance of the corresponding fault warning signals;

[0016] The database is used to store water physical parameters, water chemical parameters and water purification status parameters corresponding to each operating period of the water purification system.

[0017] Furthermore, the water body physical parameters corresponding to each operation period of the water purification system are jointly composed of the inlet water temperature, outlet water temperature, inlet water turbidity, outlet water turbidity, inlet water conductivity and outlet water conductivity corresponding to each operation period of the water purification system;

[0018] The water chemical parameters corresponding to each operation period of the water purification system are composed of the inlet pH value, outlet pH value, inlet total organic carbon, outlet total organic carbon, inlet hardness value and outlet hardness value of the water purification system corresponding to each operation period;

[0019] The water purification state parameters of the water purification system corresponding to each operating period are jointly composed of the water inlet pressure, water outlet pressure, water inlet flow rate and water outlet flow rate of the water purification system corresponding to each operating period.

[0020] Furthermore, a comprehensive calculation and analysis of the water body physical parameters corresponding to each operation period of the water purification system is performed, and the specific calculation and analysis method is as follows:

[0021] The inlet water temperature, outlet water temperature, inlet water turbidity, outlet water turbidity, inlet water conductivity and outlet water conductivity of the water purification system corresponding to each operating period are extracted from the water body physical parameters corresponding to each operating period of the water purification system, and are recorded as IW i OW i , IZ i , OZ i 、ID i and OD i ;

[0022] The difference between the inlet and outlet water temperatures of the water purification system corresponding to each operating period is calculated to obtain the water temperature difference of the water purification system corresponding to each operating period, which is recorded as ΔSW i , the difference between the inlet turbidity and outlet turbidity of the water purification system corresponding to each operating period is calculated and divided by the inlet turbidity to obtain the water turbidity removal rate of the water purification system corresponding to each operating period, recorded as RZ i Similarly, the water conductivity removal rate of the water purification system corresponding to each operating period is calculated and recorded as RD i ;

[0023] According to the formula WS i =w1*ΔSW i +w2*RZ i +w3*RD i The water physical purification state coefficient of the water purification system corresponding to each operating period is calculated, where w1, w2 and w3 all represent the set weight factors, w1+w2+w3=1.

[0024] Furthermore, a comprehensive calculation and analysis of the water chemical parameters of the water purification system corresponding to each operating period is performed, and the specific calculation and analysis method is as follows:

[0025] The inlet pH value, outlet pH value, inlet total organic carbon, outlet total organic carbon, inlet hardness value and outlet hardness value of the water purification system corresponding to each operating period are extracted from the water chemical parameters of the water purification system corresponding to each operating period. At the same time, the pH standard value, total organic carbon standard value and hardness standard value of the water purification system corresponding to each operating period are obtained from the database. The difference between the pH standard value and the minimum pH value of the water purification system corresponding to each operating period is compared with the difference between the maximum pH value and the minimum pH value to obtain the standardized pH value. Similarly, the standardized total organic carbon and hardness values ​​of the water purification system corresponding to each operating period are calculated. The standardized pH value, total organic carbon and hardness values ​​of the water purification system corresponding to each operating period are multiplied by the corresponding set weight factors and summed to obtain the water chemical purification state coefficient of the water purification system corresponding to each operating period.

[0026] Furthermore, the water purification state parameters, water physical purification state coefficients and water chemical purification state coefficients of the water purification system corresponding to each operating period are evaluated and analyzed. The specific evaluation and analysis methods are as follows:

[0027] The preset pressure-flow state coefficient threshold and filter element state coefficient threshold for each operation period of the water purification system are obtained from the database and are recorded as SY 1i and SY 2i , taking the preset pressure-flow state coefficient threshold of the water purification system corresponding to each operating period as the radius value, and the preset filter element state coefficient threshold of the water purification system corresponding to each operating period as the height value, a cylinder is drawn, and the cylinder is recorded as the water purification state parameter threshold graph; specifically, the preset pressure-flow state coefficient threshold and filter element state coefficient threshold of the water purification system corresponding to each operating period are artificially preset values ​​through a large amount of historical data and experimental data.

[0028] At the same center position, take the pressure flow state coefficient of the water system corresponding to each operating period as the radius value, and the filter element state coefficient of the water purification system corresponding to each operating period as the height value, draw another cylinder, and record the cylinder as the water purification state parameter graph;

[0029] If the volume of the water purification state parameter graph is larger than the water purification state parameter threshold graph, and the height of the water purification state parameter graph is larger than the water purification state parameter threshold graph, it indicates that the filter element of the water purification system is working abnormally, and a filter element fault signal is generated;

[0030] If the volume of the water purification state parameter graph is larger than the water purification state parameter threshold graph, and the radius of the water purification state parameter graph is larger than the water purification state parameter threshold graph, it indicates that the water purification state of the water purification system is abnormal, and a water purification abnormality signal is generated;

[0031] If the volume of the water purification state parameter graph is larger than the water purification state parameter threshold graph, and the height and radius of the water purification state parameter graph are both larger than the water purification state parameter threshold graph, it indicates that the water purification state of the water purification system and the filter element working state are abnormal, and a water purification abnormality signal and a filter element failure signal are generated;

[0032] If the volume of the water purification state parameter graph is smaller than the water purification state parameter threshold graph, it indicates that the water purification state of the water purification system is normal and the filter element is working normally, and a normal water purification signal and a normal filter element signal are generated.

[0033] Further, a preset water body physical purification state coefficient threshold value corresponding to each operation period of the water purification system is obtained from the database, and the water body physical purification state coefficient corresponding to each operation period of the water purification system is compared with the preset water body physical purification state coefficient threshold value. If the water body physical purification state coefficient of the water purification system corresponding to a certain operation period is greater than the preset water body physical purification state coefficient threshold value, it means that the water body physical purification state of the water purification system corresponding to the operation period is poor, and a physical purification early warning signal is generated. Otherwise, it means that the water body physical purification state of the water purification system corresponding to the operation period is good, and no physical purification early warning signal is generated.

[0034] Obtaining from the database a preset water chemical purification state coefficient threshold for each operating period of the water purification system, and comparing the water chemical purification state coefficient for each operating period of the water purification system with the preset water chemical purification state coefficient threshold; if the water chemical purification state coefficient for a certain operating period of the water purification system is greater than the preset water chemical purification state coefficient threshold, it indicates that the water chemical purification state of the water purification system for the operating period is poor, and a chemical purification warning signal is generated; otherwise, it indicates that the water chemical purification state of the water purification system for the operating period is good, and no chemical purification warning signal is generated;

[0035] The fault warning signal of the water purification system corresponding to each operating period is composed of the water purification abnormal signal, filter element fault signal, physical purification warning signal and chemical purification warning signal corresponding to each operating period of the water purification system.

According to the comprehensive analysis results, the accuracy of fault prediction of the operating status of the water purification system can be greatly improved, thereby ensuring that the water purification system can reduce the occurrence rate of faults and improve the timeliness of response to faults in the water purification system.

[0038] 2. In the present invention, the pressure-flow state coefficient of the water purification system corresponding to each operating time period is obtained by comprehensively calculating and analyzing the water inlet pressure, water outlet pressure, water inlet flow rate and water outlet flow rate of the water purification system corresponding to each operating time period. The pressure and flow state of the water purification system corresponding to each operating time period is analyzed and evaluated by the pressure-flow state coefficient of the water purification system corresponding to each operating time period.
