[0035] In addition, for a better illustration of the present disclosure, numerous specific details are provided in the following detailed implementation manners. Those skilled in the art should understand that the present disclosure can also be implemented without certain specific details. In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail so as to highlight the gist of the present disclosure.

[0036] Figure 1 A flowchart showing a water quality thermal pollution detection method according to an embodiment of the present disclosure is as Figure 1 shown, and the method includes:

[0037] In step S11, the water temperature measurement value of a predetermined water area is measured in real time;

[0038] In step S12, according to the climate information and time information when determining the water temperature measurement value, the water temperature prediction value of the predetermined water area is determined;

[0039] In step S13, according to the water temperature measurement value and the water temperature prediction value, the thermal pollution discrimination information of the predetermined water area is determined.

[0040] The water quality thermal pollution detection method according to an embodiment of the present disclosure can detect the water temperature in real time, improve the real-time performance of detection, and can determine whether the predetermined water area is thermally polluted through the water temperature measurement value and the water temperature prediction value, and can monitor the water quality thermal pollution in real time, providing a basis for timely discovering thermal pollution and carrying out targeted prevention and control.

[0041] In an example, a temperature measuring device can be used to measure the water temperature measurement value of a predetermined water area. For example, a thermometer, an infrared thermometer, a thermal imager, etc. can be used. The present disclosure does not limit the devices used for measuring the water temperature. In an example, the thermometer can directly obtain the water temperature measurement value by contacting the water quality of the predetermined water area. The infrared thermometer and the thermal imager, etc. can indirectly obtain the water temperature measurement value based on the infrared light radiated by the water quality of the predetermined water area.

[0042] In an example, a micro spectrometer such as a quantum dot spectrometer can also be used to measure the water temperature measurement value of a predetermined water area. Moreover, by measuring the spectral information of the water quality of the predetermined water area, other information can also be obtained. For example, the contents of various substances in the water body can be combined with the water temperature condition to further judge the water quality pollution condition. The present disclosure does not limit the application manner of the quantum dot spectrometer. Further, the water temperature and various water quality indicators can be obtained simultaneously through the quantum dot spectrometer, and there is no need to set up multiple instruments, which can save the detection cost.

[0043] In an example, the quantum dot spectrometer may include a quantum dot spectroscopy probe. The quantum dot spectroscopy probe may measure incident light (for example, light after passing through a water sample in a predetermined area and being transmitted or scattered) based on the physical and optical properties of nanocrystals to obtain spectral information of the incident light, and the spectral information may represent the water quality information of the water area. For example, the quantum dot spectroscopy probe may include a nanocrystal chip made of a variety of nanocrystals. The nanocrystal chip contains a certain arrangement of a variety of nanocrystals (for example, a nanocrystal array). Among them, each nanocrystal has different light absorption characteristics or emission characteristics. Different types of semiconductor nanocrystals, for example, can be of different materials, sizes, etc., so that the nanocrystal chip can modulate the response to wavelengths in a relatively wide wavelength range to obtain the spectrum of the incident light adjusted in a relatively wide wavelength range.

[0044] In a possible implementation, the light after being transmitted or scattered by water may be affected by substances in the water (such as suspended solids, pollutants, etc.), so as to obtain specific spectral information. The quantum dot spectroscopy probe can obtain this spectral information in real time and determine the water quality index represented by this spectral information. For example, by the absorption intensity of water samples for light of different wavelengths, spectral information of light in different frequency bands can be obtained, and the water quality index can be calculated through this spectral information. In the example, the water quality index includes chemical oxygen demand (COD), turbidity, permanganate index, total suspended solids, biological oxygen demand, total organic carbon, sulfate content, chloride content, dissolved iron content, dissolved manganese content, dissolved copper content, dissolved zinc content, nitrate content, nitrite content, total nitrogen content, fluoride content, selenium content, total arsenic content, total mercury content, total cadmium content, chromium content, total lead content, total cyanide, volatile phenol content, fecal coliform group content, sulfide content, etc. The water temperature can also be measured according to the infrared spectrum in the spectral information. Or, the quantum dot spectroscopy probe can infer the water quality index through a neural network. For example, the spectral information can be input into the neural network, and the neural network can infer the concentrations of various substances (water quality indexes). The present disclosure does not limit the method of determining the water quality index. The present disclosure does not limit the working principle of the quantum dot spectroscopy probe.

[0045] In the example, the quantum dot spectral probe can determine water quality indicators based on the light absorption characteristics of various substances contained in water. For example, the light intensity of light at a specific wavelength can be analyzed through spectral information, and then the concentration of substances corresponding to the light in the specific wavelength range (water quality indicators) can be obtained. Measuring indicators with the quantum dot spectral probe can achieve on-line, in-situ, high-frequency, and real-time measurement. When detecting water quality indicators, the spectral information of the light passing through a predetermined water area can be detected by the quantum dot spectral probe, and then the water quality indicators can be quickly calculated based on the spectral information to obtain water quality indicators with strong real-time performance. Compared with the process of bringing water quality back to the laboratory for testing, detecting with the quantum dot spectral probe has better real-time performance (that is, the detected water quality indicators are the current water quality indicators, while the time required for laboratory testing is relatively long, and during the period of waiting for the test results, the water quality indicators in the predetermined water area may have changed). By setting the quantum dot spectral probe in a preset water area and measuring multiple times within a certain period, a water quality indicator sequence of the above two water quality indicators in this water area can be obtained. The water quality indicators in the water quality indicator sequence are the water quality indicators obtained at multiple moments at the same location, so they have consistency and comparability and can be used to observe the change law of water quality indicators over a period of time to judge water pollution. For example, the measurement frequency of the quantum dot spectral probe can reach 3 - 60 minutes per time, preferably 5 - 30 minutes per time, particularly preferably 8 - 20 minutes per time, and most preferably 10 - 15 minutes per time. The measurement frequency is much higher than that of bringing water samples back to the laboratory for testing, and the quantum dot spectral probe can be set at a fixed position in the predetermined water area to ensure the consistency of water samples. When bringing water samples back to the laboratory for testing, it is difficult to ensure that the sampling is exactly at the same location for two measurements, and due to the low measurement frequency and the long interval between two measurements, even if it is possible to ensure that the sampling is exactly at the same location for two measurements, due to the fluidity of water, the water quality at this location may have changed significantly during the long interval, making it difficult to ensure the consistency of measurement and the comparability of measurement results.

[0046] In the example, in addition to the above water quality indicators, the infrared spectrum of the water quality in the predetermined water area can also be detected by the quantum dot spectral probe to determine the water temperature measurement value of the water quality. If the water temperature measurement value is abnormal, the pollution status can also be determined through the above water quality indicators to further determine the reason for the abnormal water temperature or the reason for water quality thermal pollution.

[0047] In a possible implementation manner, when measuring the water temperature, the quantum dot spectrometer can not contact the water and realize the measurement of the water temperature based on the spectral information of the reflected light of the water, which can reduce the corrosion of the instrument and extend the service life of the instrument.

[0048] In a possible implementation, in step S11, the water temperature measurement value of a predetermined water area can be measured, and the measurement time can be recorded. In the example, the water temperature of the predetermined water area can be measured multiple times, and the times of multiple measurements can be recorded.

[0049] In a possible implementation, after obtaining the water temperature measurement value, it can be determined whether the water temperature measurement value is abnormal. For example, the water temperature measurement value can be compared with the water temperature prediction value, and the water temperature prediction value can be the normal water temperature of the predetermined water area, that is, the normal water temperature that the predetermined water area should reach when the water temperature measurement value is obtained. If the difference between the water temperature measurement value and the normal water temperature is large, it can indicate that the predetermined water area is thermally polluted. Otherwise, it can indicate that the predetermined water area is not thermally polluted.

[0050] In a possible implementation, in step S12, the water temperature prediction value of the predetermined water area can be determined, that is, estimate the normal water temperature that the predetermined water area should reach when the water temperature measurement value is obtained. In the example, the normal water temperature can be estimated based on the climate information and time information when the water temperature measurement value is obtained.

[0051] In the example, the normal water temperature that the predetermined water area should reach can be estimated by measuring the water temperature at other monitoring points. For example, among other monitoring points, monitoring points with similar air temperatures to the predetermined water area (for example, the temperature difference is less than set values such as 1°C, 2°C, etc.) can be selected, and the water temperatures measured at these monitoring points can be obtained, and the average value of the water temperatures at these measurement points can be determined to estimate the normal water temperature that the predetermined water area should reach. However, there may be a problem that other measurement points are also thermally polluted, resulting in inaccurate estimated values. Or due to water body flow, although the air temperatures are similar, the water temperature differences are large, etc., which may also lead to inaccurate estimated values.

[0052] In the example, the normal water temperature that the predetermined water area should reach can also be speculated based on various factors such as climate and time. The heat received by the predetermined water area at different times of the day is different. For example, at noon, the water receives a large amount of solar thermal radiation and can receive heat conducted from the ground or air, etc., resulting in a higher water temperature. In the morning or evening, the water receives less solar thermal radiation, and the air and ground temperatures are low, and they cannot conduct much heat to the water either. Therefore, the water temperature is low.

[0053] In the example, the water temperature of the predetermined water area can also be affected by climate information. For example, in summer, the water temperature is high, and in winter, the water temperature is low. Or, on sunny days, the water temperature is high, and on rainy days, the water temperature is low.

[0054] In summary, the water temperature of the predetermined water area can be affected by the time of day (i.e., time information) and climate information. Therefore, the normal water temperature of the predetermined water area, that is, the water temperature prediction value, can be estimated by obtaining the time information and climate information when the water temperature measurement value is obtained.

[0055] In the example, the normal water temperature, i.e., the predicted water temperature value, can be predicted by a water temperature prediction model. The water temperature prediction model can be a neural network model, a regression model, etc. The present disclosure does not limit the type of the water temperature prediction model. The time information and climate information when the water temperature measurement value is obtained can be input into the water temperature prediction model to determine the predicted water temperature value.

[0056] In the example, since the influence of climate information on water temperature needs to be measured over a relatively long period of time. For example, it is necessary to measure the influence of climate information on water temperature over one year or multiple years, that is, to determine the relationship between the climate and water temperature in each season over multiple years. In the example, the relationship between the daily air temperature and the daily average value of water temperature can be determined. The daily air temperature can represent the daily climate information (for example, the air temperature is relatively low in winter and relatively high in summer), and the daily average value of water temperature can represent the water temperature. The relationship between the daily air temperature and the daily average value of water temperature can be used to represent the relationship between climate and water temperature. Further, according to actual empirical data, the linear correlation coefficient between the daily minimum air temperature and the daily average value of water temperature is relatively high (linear correlation coefficient ≥ 0.97). Therefore, the daily minimum air temperature can be used to predict the water temperature.

[0057] In a possible implementation manner, the climate information includes the minimum air temperature on the day when the water temperature measurement value is determined. Step S12 may include: inputting the minimum air temperature on the day and the time information into the water temperature prediction model to obtain the predicted water temperature value, where the water temperature prediction model includes a daily cycle feature term of water temperature and a seasonal cycle feature term of water temperature. The daily cycle feature term represents the relationship between the water temperature index and the moment when the water temperature index is measured, and the seasonal cycle feature term represents the relationship between the climate information and the water temperature index.

[0058] In the example, when determining the predicted water temperature value, the daily minimum air temperature and the time information when the water temperature measurement value is obtained can be input into the water temperature prediction model, and the water temperature prediction model can output the predicted water temperature value. The daily minimum air temperature can be used to represent the climate information and is used to estimate the seasonal cycle feature term. The time information is used to estimate the daily cycle feature term, that is, the water temperature shows a periodic change law at different moments of a day. The normal water temperature at that moment can be predicted according to the moment when the water temperature measurement value is obtained and the above law.

[0059] In a possible implementation manner, the method for establishing a water temperature prediction model may include: determining the daily cycle feature term of water temperature according to a plurality of water temperature indexes obtained in a predetermined water area within a first time period; determining the seasonal cycle feature term of water temperature according to the climate information within a second time period and a plurality of water temperature indexes obtained in the predetermined water area; and determining the water temperature prediction model according to the daily cycle feature term and the seasonal cycle feature term.

[0060] Figure 2 A schematic diagram showing the water temperature index according to an embodiment of the present disclosure. AsFigure 2 As shown, the first time period may include multiple days, and the water temperature index may be measured at multiple moments within the multiple days to obtain a water temperature index sequence \(\{(t_1,y_1),(t_2,y_2),(t_3,y_3),\cdots,(t_m,y_m),\cdots\}\), where \(m\) is any positive integer, \(t_m\) is the \(m\)-th moment, and \(y_m\) is the water temperature index measured at the \(m\)-th moment. The water temperature index may present a periodic change rule. For example, the water temperature rises at noon and drops in the morning and evening, etc. (As shown in m ,y m ),\cdots\}, where \(m\) is any positive integer, \(t_m\) is the \(m\)-th moment, and \(y_m\) is the water temperature index measured at the \(m\)-th moment. The water temperature index may present a periodic change rule. For example, the water temperature rises at noon and drops in the morning and evening, etc. (As shown in m is the \(m\)-th moment, and \(y_m\) is the water temperature index measured at the \(m\)-th moment. The water temperature index may present a periodic change rule. For example, the water temperature rises at noon and drops in the morning and evening, etc. (As shown in m ), where \(m\) is any positive integer, \(t_m\) is the \(m\)-th moment, and \(y_m\) is the water temperature index measured at the \(m\)-th moment. The water temperature index may present a periodic change rule. For example, the water temperature rises at noon and drops in the morning and evening, etc. (As shown in Figure 2 ), due to temperature changes, the water temperature shows periodic changes. However, when the climatic conditions do not change significantly, the water temperature may fluctuate around a certain temperature value (such as 25 °C). Since the water temperature shows a periodic change rule, therefore, the daily cycle characteristic term can be determined by Fourier fitting, that is, the relationship between the water temperature index and the moment when the water temperature index is measured.

[0061] In a possible implementation manner, according to multiple water temperature indexes obtained in a predetermined water area within the first time period, determining the daily cycle characteristic term of the water temperature includes: performing Fourier fitting processing on the multiple water temperature indexes obtained within the first time period and the moment when the water temperature index is obtained to obtain the daily cycle characteristic term.

[0062] In the example, the daily cycle characteristic term can be determined according to the following formula (1):

[0063]

[0064] where \(t\) is the moment when the water temperature index is obtained, \(N\) is the number of days included in the first time period, \(P\) is the minimum positive period. In the example, the minimum positive period may be 1 day, and the present disclosure does not limit the minimum positive period. \(n\) is the date when the water temperature index is obtained, and \(c_m\) n is the Fourier coefficient. \(s(t)\) is the daily cycle characteristic term, that is, the moment when the water temperature measurement value is obtained can be input into the daily cycle characteristic term, and the result output by the daily cycle characteristic term is the normal water temperature predicted based on that moment.

[0065] In a possible implementation manner, the seasonal cycle characteristic term can be determined, that is, it represents the rule of the water temperature changing with the climate change. According to the climate information within the second time period and multiple water temperature indexes obtained in the predetermined water area, determining the seasonal cycle characteristic term of the water temperature includes: performing regression analysis on the multiple water temperature indexes obtained within the second time period and the lowest temperature on the day when the water temperature index is obtained to obtain the seasonal cycle characteristic term.

[0066] In the example, the second time period may include multiple years, and there is a high correlation coefficient between the daily minimum temperature and the daily average water temperature over each day of the multiple years. Climate information can be represented by the minimum temperature, and the water temperature index can be represented by the daily average water temperature. Moreover, the relationship between the daily minimum temperature and the daily average water temperature, that is, the seasonal cycle characteristic term, can be determined.

[0067] Figure 3 A schematic diagram showing the relationship between the daily average water temperature and the minimum temperature is shown, as Figure 3 shown. There is a high correlation coefficient between the daily minimum temperature and the daily average water temperature. Regression analysis can be performed on the daily minimum temperature and the daily average water temperature to obtain the seasonal cycle characteristic term. In the example, the seasonal cycle characteristic term can be determined by the following formula (2):

[0068] g(t) = kT env,daily_min + b (2)

[0069] where k is the regression coefficient, b is the intercept, T env,daily_min is the daily minimum temperature, and g(t) is the seasonal cycle characteristic term. That is, the climate information (i.e., the daily minimum temperature) for obtaining the water temperature measurement value can be input into the seasonal cycle characteristic term, and the result output by the seasonal cycle characteristic term is the normal water temperature based on this minimum temperature.

[0070] In one possible implementation, after determining the daily cycle characteristic term and the seasonal cycle characteristic term, a water temperature prediction model can be obtained using the daily cycle characteristic term and the seasonal cycle characteristic term. In the example, determining the water temperature prediction model according to the daily cycle characteristic term and the seasonal cycle characteristic term may include: performing a summation process on the daily cycle characteristic term and the seasonal cycle characteristic term to obtain the water temperature prediction model.

[0071] In the example, the water temperature prediction model can be determined by the following formula (3):

[0072]

[0073] where is the water temperature prediction value.

[0074] In the example, the water temperature prediction model can refer to climate information and time information to obtain the normal water temperature, that is, the water temperature prediction value. The above two items can be summed up to obtain the normal water temperature that should be reached in a predetermined water area at the moment of obtaining the water temperature measurement value under the daily minimum temperature, that is, the water temperature prediction value. For example, the moment of obtaining the water temperature measurement value is 15:00 in the afternoon, the season of the day is summer, and the daily minimum temperature is 28°C. The time information (15:00) and the climate information (28°C) can be input into the water temperature prediction model to obtain the water temperature prediction value, that is, the normal water temperature that should be reached in the predetermined water area at 15:00 in the afternoon under the condition that the daily minimum temperature is 28°C.

[0075] In this way, the water temperature prediction model can refer to time information and climate information, fully consider multiple factors affecting the water temperature, and improve the accuracy of the water temperature prediction value.

[0076] In the example, the factors affecting the water temperature prediction value may further include the presence or absence of inflowing water. In the case where the predetermined water area is the ocean, the factors affecting the water temperature prediction value may further include tides, etc. The above factors may also be added to the water temperature prediction model, and the present disclosure does not limit the factors affecting the water temperature prediction value.

[0077] In a possible implementation manner, in step S13, the water temperature measurement value and the water temperature prediction value may be compared. Among them, the water temperature prediction value is the normal temperature that the predetermined water area should reach, and the water temperature measurement value is the measured temperature. If the deviation between the water temperature measurement value and the water temperature prediction value is large, the water temperature at this moment is abnormal, and a thermal pollution event may occur.

[0078] In a possible implementation manner, step S13 may include: determining the difference between the water temperature measurement value and the water temperature prediction value; in the case where the difference is greater than or equal to a preset threshold, determining the thermal pollution discrimination information as abnormal water temperature.

[0079] In the example, a preset threshold ε of the water temperature deviation may be set, and the difference between the water temperature measurement value y(t) and the water temperature prediction value is determined. For example, the absolute value of the difference If If then it can be considered that the deviation between the water temperature measurement value and the normal water temperature is within a reasonable range, and there is no thermal pollution event. If then it can be considered that the deviation between the water temperature measurement value and the normal water temperature is large, exceeding the normal range, and there may be a thermal pollution event. The water temperature measurement value y(t) may be the measurement value at any moment, or the average value of multiple measurements, or the maximum value of multiple measurements, etc. The present disclosure does not limit the water temperature measurement value.

[0080] According to the water quality thermal pollution detection method of the embodiments of the present disclosure, the water temperature can be detected in real time, improving the real-time performance of the detection, and it can be determined whether the predetermined water area is thermally polluted through the water temperature prediction model. The water temperature prediction model can fully consider multiple factors affecting the water temperature and improve the accuracy of the water temperature prediction value. Further, the method can monitor the water quality thermal pollution in real time, providing a basis for timely discovering thermal pollution and carrying out targeted prevention and control.

[0081] Figure 4 Show an application schematic diagram of the water quality thermal pollution detection method according to the embodiments of the present disclosure, as Figure 4As shown, a quantum dot spectrometer can be set in a predetermined water area to measure the water temperature. The quantum dot spectrometer can obtain real-time and high-frequency water temperature measurement values through spectral line information in the infrared band.

[0082] In a possible implementation, when determining whether there is a water quality thermal pollution event at a certain moment, the daily minimum temperature and the time information when the water temperature measurement value is obtained can be input into the water temperature prediction model, and the water temperature prediction value can be obtained.

[0083] In a possible implementation, the water temperature prediction model can include a seasonal cycle feature term and a daily cycle feature term. The daily cycle feature term represents the relationship between the water temperature index and the moment when the measured water temperature index is obtained, and the seasonal cycle feature term represents the relationship between the climate information and the water temperature index.

[0084] In a possible implementation, the daily minimum temperature can represent the climate information. The seasonal cycle feature term can process the daily minimum temperature to obtain the predicted water temperature under this temperature condition. The daily cycle feature term can process the time information to obtain the predicted water temperature at this moment. The above two predicted water temperatures can be summed to obtain the water temperature prediction value, that is, the water temperature that the predetermined water area should reach under this temperature condition at this moment.

[0085] In a possible implementation, whether a water quality thermal pollution event occurs can be determined by the deviation between the water temperature measurement value and the water temperature prediction value. A preset threshold of the water temperature deviation can be set, and the difference between the water temperature measurement value and the water temperature prediction value can be determined. If this difference is greater than or equal to the preset threshold, it can be considered that the deviation between the water temperature measurement value and the normal water temperature is large, exceeding the normal range, and there may be a thermal pollution event. Otherwise, it can be considered that the deviation between the water temperature measurement value and the normal water temperature is within a reasonable range and there is no thermal pollution event.

[0086] Furthermore, if there is a thermal pollution event, other water quality indicators can also be measured by the quantum dot spectrometer to further determine the specific situation of water quality pollution. The present disclosure does not limit the usage method of the quantum dot spectrometer.

[0088] In a possible implementation, the climate information includes the lowest temperature on the day when the water temperature measurement value is determined. The prediction module may include: inputting the lowest temperature on the day and the time information into a water temperature prediction model to obtain the water temperature prediction value. Wherein, the water temperature prediction model includes a daily cycle feature term of the water temperature and a seasonal cycle feature term of the water temperature. The daily cycle feature term represents the relationship between the water temperature index and the moment when the water temperature index is measured, and the seasonal cycle feature term represents the relationship between the climate information and the water temperature index.
