[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1As shown, it is a structural schematic diagram of the water affairs dynamic monitoring system based on digital twin provided in the embodiment of the present application. The water affairs dynamic monitoring system based on digital twin provided in the embodiment of the present application includes: a data acquisition module, an equipment data processing module, a water affairs data processing module and a water affairs detection database; wherein, the data acquisition module is used to acquire equipment working environment data, performance data of each monitoring equipment and water affairs data, wherein the water affairs data includes hydrological data and water quality data; the equipment data processing module is used to obtain the equipment working environment evaluation value according to the comprehensive analysis of the equipment working environment data, obtain the performance evaluation value of each monitoring equipment according to the comprehensive analysis of the performance data of each monitoring equipment, obtain the status evaluation value of each monitoring equipment according to the comprehensive analysis of the equipment working environment evaluation value and the performance evaluation value of each monitoring equipment, and perform evaluation feedback according to the status evaluation value of each monitoring equipment; the water affairs data processing module is used to obtain the water quality evaluation value according to the comprehensive analysis of the water quality data, and finally obtain the water affairs status evaluation value according to the comprehensive analysis of the water quality evaluation value, the equipment working environment evaluation value and the hydrological data, and perform evaluation feedback according to the water affairs status evaluation value.

[0033] In this embodiment, the equipment working environment data and performance data of each environmental monitoring point can be monitored and acquired by deploying sensors, and the digital twin technology is used to build a virtual model of each device, and the real-time data collected by the sensor is synchronized to the digital twin model, that is, the equipment working environment evaluation value and the performance evaluation value calculation formula of each monitoring device, so as to realize the real-time monitoring and evaluation of the equipment working environment and performance data; in the comprehensive evaluation of water affairs status, by building a digital twin of the water affairs system, multi-source information such as water quality data, equipment working environment data and hydrological data can be collected and integrated in real time, and the digital twin can conduct a comprehensive analysis of these data (that is, using the water quality evaluation value calculation formula and the water affairs status evaluation value calculation formula) to obtain the water affairs status evaluation value. Through the above process, the efficiency of equipment maintenance and management can be improved, and the water quality safety of water affairs can be guaranteed.

[0034] In addition, the water conservancy detection database is used to store relevant data of the water conservancy dynamic monitoring system based on digital twins, including: reference ambient temperature, allowable deviation ambient temperature, reference ambient humidity, allowable deviation ambient humidity, critical ambient air pressure value, critical equipment working environment assessment value, critical performance assessment value, status assessment threshold and cumulative operating time corresponding to the monitoring equipment performance assessment influencing factor, etc. The data in the water conservancy detection database can be obtained by contacting the water conservancy department to apply for data sharing or purchasing data, or can be queried and downloaded from the online water conservancy database platform and related open data platforms, or collected through cooperation with relevant scientific research institutions.

[0035] Furthermore, the step of obtaining an equipment working environment evaluation value based on a comprehensive analysis of the equipment working environment data includes: the equipment working environment data includes ambient temperature, ambient humidity and ambient air pressure; obtaining a reference ambient temperature, an allowable deviation ambient temperature, a reference ambient humidity, an allowable deviation ambient humidity, a reference ambient air pressure value and an allowable deviation ambient air pressure value from a water conservancy inspection database; and obtaining an equipment working environment evaluation value through a comprehensive analysis.

[0036] The device working environment evaluation value is obtained as follows:

[0037]

[0038] In the formula, ζE1 represents the equipment working environment assessment value, β1 represents the environmental assessment impact factor corresponding to the ambient temperature, β2 represents the environmental assessment impact factor corresponding to the ambient humidity, β3 represents the environmental assessment impact factor corresponding to the ambient pressure, T 1k represents the ambient temperature of the kth environmental monitoring point, T0 represents the reference ambient temperature, T2 represents the allowable deviation ambient temperature, H 1h represents the ambient humidity of the kth environmental monitoring point, H0 represents the reference ambient humidity, H2 represents the allowable deviation ambient humidity, P 1k represents the ambient air pressure value of the kth environmental monitoring point, P0 represents the reference ambient air pressure value, P2 represents the allowable deviation ambient air pressure value, where k is the number of the environmental monitoring point, k=1,2,3,...,K, and K is the number of environmental monitoring points.

[0039] β1, β2 and β3 are respectively the equipment working environment assessment influencing factors corresponding to the ambient temperature, ambient humidity and ambient air pressure preset in the water conservancy detection database, which respectively represent the numerical values ​​of the degree of influence of the ambient temperature, ambient humidity and ambient air pressure on the equipment working environment assessment value, and can be directly obtained from the water conservancy detection database when used. For example, the ambient temperature and the equipment working environment assessment influencing factors corresponding to the ambient temperature preset in the water conservancy detection database form a mapping set, and the equipment working environment assessment influencing factors corresponding to the ambient temperature are obtained by inputting the mapping set according to the ambient temperature; the ambient humidity and the equipment working environment assessment influencing factors corresponding to the ambient humidity preset in the water conservancy detection database form a mapping set, and the equipment working environment assessment influencing factors corresponding to the ambient humidity are obtained by inputting the mapping set according to the ambient humidity; the ambient air pressure and the equipment working environment assessment influencing factors corresponding to the ambient air pressure preset in the water conservancy detection database form a mapping set, and the equipment working environment assessment influencing factors corresponding to the ambient air pressure are obtained by inputting the mapping set according to the ambient air pressure, wherein the mapping relationship is a many-to-one or one-to-one relationship, and the value range of the influencing factor in this embodiment is between 0 and 1.

[0040] In this embodiment, the ambient temperature is usually measured by a temperature sensor, the ambient humidity can be obtained by measuring the humidity sensor, and the ambient air pressure can be obtained by measuring the air pressure sensor. There is a certain correlation between the ambient temperature, ambient humidity and ambient air pressure. For example, in a closed space, as the temperature rises, the moisture in the air may evaporate, resulting in a decrease in humidity; at the same time, the change in temperature may also affect the stability of the air pressure; in addition, the change in humidity and air pressure may also have a mutual impact on the operation of the device. By comprehensively analyzing the ambient temperature, ambient humidity and ambient air pressure, the working environment of the device can be comprehensively evaluated, and the operation adjustment of the device can be adjusted to ensure that it operates in the best state, which helps to improve the stability and reliability of the device. When the device working environment evaluation value is lower than the critical device working environment evaluation value, it means that there is a problem with the current device working environment, which needs to be adjusted and processed in time, and can be processed according to the ambient temperature, ambient humidity and ambient air pressure values. For example, when the absolute value of the difference between the ambient temperature and the reference ambient temperature is greater than or equal to the allowable deviation ambient humidity, it means that there is a problem with the device working temperature. The sensor or circuit element inside the detection device may work abnormally due to the excessively high temperature, thereby interfering with the normal monitoring work, and it is necessary to cool down in time.

[0041] Furthermore, the step of obtaining the performance evaluation value of each monitoring device through comprehensive analysis based on the performance data of each monitoring device includes: the performance data of each monitoring device includes the cumulative operating time, noise intensity and vibration frequency of each monitoring device; obtaining the critical cumulative operating time, reference noise intensity, allowable deviation noise intensity, reference vibration frequency and allowable deviation vibration frequency from the water conservancy detection database; and obtaining the performance evaluation value of each monitoring device through comprehensive analysis.

[0042] The performance evaluation value of each monitoring device is obtained as follows:

[0043]

[0044] In the formula, ζP 1i represents the performance evaluation value of the i-th monitoring device, β4 represents the monitoring device performance evaluation influencing factor corresponding to the cumulative operating time, β5 represents the monitoring device performance evaluation influencing factor corresponding to the noise intensity, β6 represents the monitoring device performance evaluation influencing factor corresponding to the vibration frequency, R 1i represents the cumulative operating time of the i-th monitoring device, R0 represents the critical cumulative operating time, N 1i represents the noise intensity of the i-th monitoring device, N0 represents the reference noise intensity, N2 represents the allowable deviation vibration intensity, and F 1i represents the vibration frequency of the i-th monitoring device, F0 represents the reference vibration frequency, F2 represents the allowable deviation vibration frequency, i is the monitoring device number, i=1,2,3,...,N, N is the number of monitoring devices.

[0045] β4, β5 and β6 are monitoring equipment performance evaluation influencing factors corresponding to the cumulative operating time, noise intensity and vibration frequency preset in the water conservancy detection database, respectively, and represent the numerical values ​​of the degree of influence of the cumulative operating time, noise intensity and vibration frequency on the performance evaluation value of the monitoring equipment, and can be directly obtained from the water conservancy detection database when used. For example, the cumulative operating time and the monitoring equipment performance evaluation influencing factors corresponding to the cumulative operating time preset in the water conservancy detection database form a mapping set, and the monitoring equipment performance evaluation influencing factors corresponding to the cumulative operating time are obtained by inputting the mapping set according to the cumulative operating time; the noise intensity and the monitoring equipment performance evaluation influencing factors corresponding to the noise intensity preset in the water conservancy detection database form a mapping set, and the monitoring equipment performance evaluation influencing factors corresponding to the noise intensity are obtained by inputting the mapping set according to the noise intensity; the vibration frequency and the monitoring equipment performance evaluation influencing factors corresponding to the vibration frequency preset in the water conservancy detection database form a mapping set, and the monitoring equipment performance evaluation influencing factors corresponding to the vibration frequency are obtained by inputting the mapping set according to the vibration frequency, wherein the mapping relationship is a many-to-one or one-to-one relationship, and the value range of the influencing factor in this embodiment is between 0 and 1.

[0046] In this embodiment, the cumulative running time can be obtained by the built-in timer or data recording system of the monitoring device, which can track the running time of the device in real time and provide the value of the cumulative running time when needed; the noise intensity refers to the noise intensity inside the device, which can be measured using professional noise monitoring equipment (such as noise analyzer); the vibration frequency refers to the vibration frequency inside the monitoring device when it is working, which can be measured using a vibration sensor. There is a certain correlation between the three parameters of cumulative running time, noise intensity and vibration frequency. For example, as the cumulative running time of the device increases, the wear and aging of the device may increase, resulting in an increase in noise intensity and vibration frequency. In addition, the changes in noise intensity and vibration frequency may also reflect the operating status and performance of the device. By comprehensively analyzing the values ​​of the three parameters of cumulative running time, noise intensity and vibration frequency, the performance of the device can be comprehensively evaluated and potential faults can be discovered in a timely manner. According to the performance evaluation values ​​of each monitoring device, the operating conditions of the device can be adjusted (such as reducing the running time, reducing the load, etc.) to reduce the noise intensity and vibration frequency and improve the stability and reliability of the device.

[0047] Furthermore, the step of obtaining the status evaluation value of each monitoring device by comprehensive analysis based on the equipment working environment evaluation value and the performance evaluation value of each monitoring device includes: obtaining the critical equipment working environment evaluation value and the critical performance evaluation value from the water conservancy detection database; and obtaining the status evaluation value of each monitoring device by comprehensive analysis.

[0048] The state evaluation value of each monitoring device is obtained as follows:

[0049]

[0050] Where ζS 1i represents the status evaluation value of the i-th monitoring device, β7 represents the monitoring device status evaluation influencing factor corresponding to the device working environment evaluation value, β8 represents the monitoring device status evaluation influencing factor corresponding to the performance evaluation value, ζE1 represents the device working environment evaluation value, ζE0 represents the critical device working environment evaluation value, ζP 1i represents the performance evaluation value of the i-th monitoring device, and ζP0 represents the critical performance evaluation value.

[0051] β7 and β8 are monitoring equipment status assessment influencing factors corresponding to the equipment working environment assessment value and the performance assessment value preset in the water conservancy detection database, respectively, and represent the numerical values ​​of the degree of influence of the equipment working environment assessment value and the performance assessment value on the monitoring equipment status assessment value, respectively, and can be directly obtained from the water conservancy detection database when used. For example, the equipment working environment assessment value and the monitoring equipment status assessment influencing factors corresponding to the equipment working environment assessment value preset in the water conservancy detection database form a mapping set, and the monitoring equipment status assessment influencing factors corresponding to the equipment working environment assessment value are obtained by inputting the mapping set according to the equipment working environment assessment value; the performance assessment value and the monitoring equipment status assessment influencing factors corresponding to the performance assessment value preset in the water conservancy detection database form a mapping set, and the monitoring equipment status assessment influencing factors corresponding to the performance assessment value are obtained by inputting the mapping set according to the performance assessment value, wherein the mapping relationship is a many-to-one or one-to-one relationship, and the value range of the influencing factor in this embodiment is between 0 and 1.

[0052] In this embodiment, the equipment working environment evaluation value mainly reflects the overall condition of the environment in which the equipment is located, and the performance evaluation value of each monitoring device focuses on the operating status and performance of the equipment itself. These two evaluation values ​​are complementary in content and together constitute a comprehensive evaluation of the status of the monitoring equipment. In addition, the quality of the equipment working environment may directly affect the performance and operating status of the equipment. For example, too high a temperature may cause the equipment to overheat, thereby affecting its performance and life. Similarly, the performance of the equipment may also have a feedback effect on environmental factors. For example, the vibration and noise generated when the equipment is running may interfere with the surrounding environment. Therefore, by comprehensively analyzing the equipment working environment evaluation value and the performance evaluation value of each monitoring device, the equipment status can be comprehensively evaluated, and the evaluation accuracy can be improved. According to the comprehensive analysis, a more scientific and reasonable equipment maintenance strategy can be formulated. For example, for equipment in a harsh environment with degraded performance, it may be necessary to strengthen maintenance and maintenance work; while for equipment with a good environment and stable performance, the maintenance cycle can be appropriately extended.

[0053] The monitoring equipment status evaluation impact factor corresponding to the equipment working environment evaluation value is set to 0.4, the monitoring equipment status evaluation impact factor corresponding to the performance evaluation value is set to 0.6, the equipment working environment evaluation value is set to 1.2, the critical equipment working environment evaluation value is set to 1.15, and the critical performance evaluation value is set to 1.4. When the performance evaluation value of a certain monitoring equipment is constantly changing, the status evaluation value of the monitoring equipment is calculated. As shown in Table 1, the data table of the monitoring equipment status evaluation value of the water affairs dynamic monitoring system based on digital twins.

[0054] Table 1 Data table of monitoring equipment status evaluation value of water affairs dynamic monitoring system based on digital twin

[0055] serial number <![CDATA[ζP 1i ]]> <![CDATA[ζS 1i ]]> 1 1.3 1.691 2 1.35 1.697 3 1.4 1.702 4 1.45 1.708 5 1.5 1.714

[0056] like Figure 2 As shown in Table 1 and Figure 2 It can be seen that when the monitoring equipment state evaluation influence factor corresponding to the equipment working environment evaluation value, the monitoring equipment state evaluation influence factor corresponding to the performance evaluation value, the equipment working environment evaluation value, the critical equipment working environment evaluation value and the critical performance evaluation value remain unchanged, as the performance evaluation value of the monitoring equipment continues to increase, the state evaluation value of the monitoring equipment also continues to increase.

[0057] Furthermore, the step of providing evaluation feedback based on the status evaluation value of each monitoring device includes: obtaining a status evaluation threshold from a water conservancy detection database; comparing the status evaluation value of each monitoring device with the status evaluation threshold; if the status evaluation value of a monitoring device is less than the status evaluation threshold, the detection device is marked as an unqualified device, and feedback adjustment is performed; if the status evaluation value of a monitoring device is greater than or equal to the status evaluation threshold, the detection device is marked as a qualified device.

[0058] In this embodiment, the state evaluation threshold is a critical value used to determine whether the state of the monitoring device is qualified. When the state evaluation value of a certain monitoring device is less than the state evaluation threshold, it means that the state of the monitoring device is abnormal. The difference between the state evaluation threshold and the state evaluation value of each monitoring device can be marked as the state evaluation difference, and the device state is divided into different levels according to the state evaluation difference, including the first level, the second level and the third level. When the state evaluation difference is at the first level, it means that the abnormality of the monitoring device is relatively light, and planned maintenance can be arranged in the near future to conduct a comprehensive inspection and maintenance of the equipment, while increasing the frequency of daily inspections of the equipment to timely discover and deal with potential problems; when the state evaluation difference is at the second level, it means that the abnormality of the monitoring device is relatively serious, and the operating parameters of the equipment can be adjusted to delay the occurrence of failures, and preventive maintenance can be performed during the maintenance process; when the state evaluation difference is at the third level, it means that the abnormality of the state of the monitoring device is very serious, and it is necessary to stop the machine immediately for inspection, and perform necessary emergency repairs or replace key components according to the inspection results. After the maintenance is completed, the continuous monitoring of the equipment is strengthened to ensure that the equipment state returns to normal. For example, the current status assessment value of a monitoring device is 1.10, and the status assessment threshold is 1.25, so the current status assessment difference is 0.15. The status assessment difference interval corresponding to the first level preset in the water conservancy detection database is (0, 0.1), and the status assessment difference interval corresponding to the second level is [0.1, 0.2]. The status assessment difference interval corresponding to the third level is greater than 0.2, so the current status abnormality level of the monitoring device is the second level.

[0059] Furthermore, the step of obtaining a water quality assessment value based on a comprehensive analysis of water quality data includes: the water quality data includes a pH value, a dissolved oxygen concentration, and concentrations of various pollutants; obtaining a reference pH value, an allowable deviation pH value, a reference dissolved oxygen concentration, an allowable deviation dissolved oxygen concentration, and concentrations of various critical pollutants from a water service inspection database; and obtaining a water quality assessment value through a comprehensive analysis.

[0060] The water quality assessment value is obtained as follows:

[0061]

[0062] Where ξQ represents the water quality assessment value, α5 represents the water quality assessment influencing factor corresponding to the pH value, α6 represents the water quality assessment influencing factor corresponding to the dissolved oxygen concentration, α7 represents the water quality assessment influencing factor corresponding to each pollutant concentration, PH1 represents the pH value, PH0 represents the reference pH value, PH2 represents the allowable deviation pH value, O1 represents the dissolved oxygen concentration, O0 represents the reference dissolved oxygen concentration, O2 represents the allowable deviation dissolved oxygen concentration, PC 1j represents the jth pollutant concentration, PC 0jrepresents the jth critical pollutant concentration, where j is the pollutant number, j = 1, 2, 3, ..., M, and M is the number of pollutants.

[0063] α5, α6 and α7 are respectively the water quality assessment influencing factors corresponding to the pH value, dissolved oxygen concentration and each pollutant concentration preset in the water affairs detection database, which respectively represent the numerical values ​​of the influence degree of the pH value, dissolved oxygen concentration and each pollutant concentration on the water quality assessment value, and can be directly obtained from the water affairs detection database when used. For example, the pH value and the water quality assessment influencing factors corresponding to the pH value preset in the water affairs detection database form a mapping set, and the water quality assessment influencing factors corresponding to the pH value are obtained by inputting the mapping set according to the pH value; the dissolved oxygen concentration and the water quality assessment influencing factors corresponding to the dissolved oxygen concentration preset in the water affairs detection database form a mapping set, and the water quality assessment influencing factors corresponding to the dissolved oxygen concentration are obtained by inputting the mapping set according to the dissolved oxygen concentration; each pollutant concentration and the water quality assessment influencing factors corresponding to each pollutant concentration preset in the water affairs detection database form a mapping set, and the water quality assessment influencing factors corresponding to each pollutant concentration are obtained by inputting the mapping set according to each pollutant concentration, wherein the mapping relationship is a many-to-one or one-to-one relationship, and the value range of the influencing factor in this embodiment is between 0 and 1.

[0064] In this embodiment, pH value is an indicator of the acidity and alkalinity of water, which reflects the acid-base state of water and can be measured using a pH meter or test paper; dissolved oxygen concentration is an indicator of the oxygen content in water and can be measured using a dissolved oxygen meter; each pollutant includes mercury, cadmium, amino acids, proteins, aldehydes, ketones, cesium and sand, wherein the mercury content can be measured by an atomic fluorescence spectrometer, the cadmium content can be measured by an electrochemical analysis method, the amino acid content can be measured by a ninhydrin colorimetric method, the protein content can be measured by a protein analysis method, the aldehyde and ketone content can be measured by a gas chromatography or liquid chromatography method, the cesium content can be measured by an atomic absorption spectrophotometer, and the sand content can be directly obtained by a weighing method or a volumetric method. Among them, the pH value, the dissolved oxygen concentration and the concentration of each pollutant are related. The higher the pH value, the lower the redox potential is usually, which may lead to an increase in the content of reducing substances or organic pollutants in the wastewater, thereby reducing the dissolved oxygen concentration. On the contrary, the lower the pH value, the higher the redox potential, indicating that the concentration of organic pollutants in the wastewater may be low, and the concentration of dissolved oxygen or oxidizing substances is high. In addition, there are heavy metal pollutants, such as mercury and cadmium, which interfere with the respiration of microorganisms and may reduce the dissolved oxygen concentration of the water body. Since they will react chemically with other substances in the water body, they will also affect the pH value of the water body. Inorganic pollutants such as cesium and sand may affect the turbidity of the water body, thereby affecting the diffusion of dissolved oxygen and the growth of microorganisms. Through comprehensive analysis of pH value, dissolved oxygen concentration and concentration of various pollutants, we can fully understand the quality of the water body, help identify the possible sources and types of pollution in the water body, and provide a basis for formulating targeted treatment measures.

[0065] Furthermore, a water status assessment value is obtained through comprehensive analysis: the hydrological data includes water flow velocity and water level change rate; the reference water flow velocity, allowable deviation water flow velocity, critical water level change rate, critical water quality assessment value and critical equipment working environment assessment value are obtained from the water detection database; the water status assessment value is obtained through comprehensive analysis based on the water quality assessment value, equipment working environment assessment value and hydrological data.

[0066] In this embodiment, the water flow velocity can be measured by using a flow meter (such as an impeller flow meter, a Doppler flow meter, a photoelectric flow meter, etc.), and the water level change rate can be measured by using a water level meter or a water level sensor to monitor the change of the water level in real time. If the water level change rate is too large, the stability of the water supply system may be affected. For example, in the case of a river or a reservoir as a water source, if the water level rises or falls rapidly, the position of the water intake may change, thereby affecting the continuity and stability of the water supply. Therefore, the greater the water level change rate, the smaller the water service status assessment value; the water quality assessment value and the equipment working environment assessment value can be obtained by the above-mentioned related calculation formulas. These parameters also have a certain correlation. For example, when the water quality deteriorates, it may increase the burden on the equipment, accelerate the aging and damage of the equipment, and thus reduce the equipment working environment assessment value; a faster water flow rate helps the diffusion and degradation of pollutants and improves the self-purification capacity of the water body. On the contrary, a slow water flow rate may cause pollutants to accumulate in the water body and reduce the water quality assessment value; frequent or drastic water level changes may cause impacts on water treatment equipment and affect the stability and safety of the equipment. By comprehensively analyzing water quality assessment values, equipment working environment assessment values, water flow velocity and water level change rate, we can accurately obtain water status assessment values, which reflects the overall operating status of the water system, helps to promptly discover problems in the water system, and provides a basis for formulating targeted solutions.

[0067] Furthermore, the water service status assessment value is obtained as follows:

[0068]

[0069] In the formula, ξS represents the water conservancy status assessment value, α1 represents the water conservancy monitoring equipment status assessment influencing factor corresponding to the water flow velocity, α2 represents the water conservancy monitoring equipment status assessment influencing factor corresponding to the water level change rate, α3 represents the water conservancy monitoring equipment status assessment influencing factor corresponding to the monitoring equipment environment, α4 represents the water conservancy monitoring equipment status assessment influencing factor corresponding to the water quality, V1 represents the water flow velocity, V0 represents the reference water flow velocity, V2 represents the allowable deviation water flow velocity, C1 represents the water level change rate, C0 represents the critical water level change rate, ζE1 represents the equipment working environment assessment value, ζE0 represents the critical equipment working environment assessment value, ξQ1 represents the water quality assessment value, ξQ0 represents the critical water quality assessment value, and e is a natural constant, where i is the monitoring equipment number, i=1,2,3,...,N, and N is the number of monitoring equipment.

[0070] In this embodiment, α1, α2, α3 and α4 are water status assessment influencing factors corresponding to water flow velocity, water level change rate, equipment working environment and water quality preset in the water service detection database, respectively representing the numerical values ​​of the influence of water flow velocity, water level change rate, equipment working environment and water quality on the water service status assessment value, and can be directly obtained from the water service detection database when used. For example, a mapping set is formed between water flow velocity and water status assessment influencing factors corresponding to water flow velocity preset in a water affairs detection database, and the water status assessment influencing factors corresponding to the water flow velocity are obtained by inputting the mapping set according to the water flow velocity; a mapping set is formed between water level change rate and water status assessment influencing factors corresponding to water level change rate preset in a water affairs detection database, and the water status assessment influencing factors corresponding to the water level change rate are obtained by inputting the mapping set according to the water level change rate; a mapping set is formed between equipment working environment assessment value and water status assessment influencing factors corresponding to equipment working environment preset in a water affairs detection database, and the water status assessment influencing factors corresponding to the equipment working environment are obtained by inputting the mapping set according to the equipment working environment assessment value; a mapping set is formed between water quality assessment value and water status assessment influencing factors corresponding to water quality preset in a water affairs detection database, and the water status assessment influencing factors corresponding to the water quality are obtained by inputting the mapping set according to the water quality assessment value, wherein the mapping relationship is a many-to-one or one-to-one relationship, and the value range of the influencing factor in this embodiment is between 0 and 1.

[0071] Furthermore, the step of providing evaluation feedback based on the water affairs status evaluation value includes: obtaining a water affairs status evaluation threshold from a water affairs detection database; comparing the water affairs status evaluation value with the water affairs status evaluation threshold; if the water affairs status evaluation value is greater than or equal to the water affairs status evaluation threshold, the water affairs status is evaluated as good; if the water affairs status evaluation value is less than the water affairs status evaluation threshold, the water affairs status is evaluated as abnormal, and adjustment feedback is provided.

[0072] In this embodiment, the water status assessment threshold is a standard value or boundary value used to measure whether the water status is good. By setting the water status assessment threshold, a standardized assessment system can be established to make the assessment of the water status more objective, accurate and comparable. This helps to eliminate subjectivity and uncertainty in the assessment process and improve the reliability and effectiveness of the assessment results. When the water status assessment value is less than the water status assessment threshold, it means that the water status is poor and there may be potential problems or risks, which require timely adjustment and feedback. The water quality assessment value, the equipment working environment assessment value and the hydrological data can be compared with their critical values, and according to the comparison results, corresponding adjustment measures can be formulated to improve the water status, which helps to avoid further deterioration and expansion of the problem and ensure the normal operation of the water system and water supply safety. For example, when it is found that the water quality assessment value is lower than the critical water quality assessment value, measures such as strengthening water quality monitoring, optimizing water treatment technology, and adding water treatment equipment can be taken to improve water quality; when it is found that the equipment working environment assessment value is lower than the critical equipment working environment assessment value, the maintenance and care of the equipment can be strengthened to improve the performance and stability of the equipment; when the absolute value of the difference between the water flow velocity and the reference water flow velocity is greater than or equal to the allowable deviation water flow velocity, the diameter of the water outlet can be changed by replacing the pipe of the water pump outlet, thereby affecting the water flow velocity. The smaller the outlet diameter, the slower the water flow velocity will usually be, and conversely, the larger the outlet diameter, the faster the water flow velocity will be; when the water level change rate is greater than or equal to the critical water level change rate, the water level can be controlled by adjusting the flood discharge volume, or the water level change rate can be slowed down by building dams, adjusting the direction of the river, etc.

[0073] Furthermore, a dynamic monitoring method for water affairs based on digital twins is characterized in that: specific steps include: obtaining equipment working environment data, performance data of each monitoring equipment and water affairs data, wherein the water affairs data include hydrological data and water quality data; obtaining an equipment working environment evaluation value based on a comprehensive analysis of the equipment working environment data, obtaining a performance evaluation value of each monitoring equipment based on a comprehensive analysis of the performance data of each monitoring equipment, obtaining a status evaluation value of each monitoring equipment based on a comprehensive analysis of the equipment working environment evaluation value and the performance evaluation value of each monitoring equipment, and providing evaluation feedback based on the status evaluation value of each monitoring equipment; obtaining a water quality evaluation value based on a comprehensive analysis of the water quality data, and finally obtaining a water affairs status evaluation value based on a comprehensive analysis of the water quality evaluation value, the equipment working environment evaluation value and the hydrological data, and providing evaluation feedback based on the water affairs status evaluation value.

[0074] To summarize, this embodiment obtains an equipment working environment evaluation value by comprehensive analysis based on the equipment working environment data, obtains a performance evaluation value of each monitoring device by comprehensive analysis based on the performance data of each monitoring device, obtains a status evaluation value of each monitoring device by comprehensive analysis based on the equipment working environment evaluation value and the performance evaluation value of each monitoring device, and performs evaluation feedback based on the status evaluation value of each monitoring device; obtains a water quality evaluation value by comprehensive analysis based on the water quality data, and finally obtains a water status evaluation value by comprehensive analysis based on the water quality evaluation value, the equipment working environment evaluation value and the hydrological data, and performs evaluation feedback based on the water status evaluation value, so as to comprehensively and accurately grasp the status and changing trends of each key element in the water system, thereby effectively solving the problem of inaccurate evaluation in the monitoring and evaluation of the water system.
