[0033] Figure 2 is a flowchart of a water quality detection method provided by an embodiment of the present application. Figure 2 The water quality detection method of Figure 1 may be executed by the water quality detection master control 109 in

[0034] Please refer to Figure 2 The water quality detection method may specifically include the following steps:

[0035] Step S201: During the operation of the industrial boiler equipment, the water quality detection results of the feedwater pipeline section, the blowdown pipeline section, the drainage pipeline section, and the circulating water pipeline section of the industrial boiler equipment are synchronously obtained.

[0036] Please refer to Figure 1 As an example, during the operation of the industrial boiler equipment, the water quality detection master control 109 may distribute a water quality detection instruction to the first water quality detection sub-control 105, the second water quality detection sub-control 106, the third water quality detection sub-control 107, and the fourth water quality detection sub-control 108.

[0037] Step S202: Based on the water quality detection results of each pipeline section, the water quality key detection points, the water quality ordinary detection points corresponding to each pipeline section, and the node correlation coefficients between them are determined, and based on the node correlation coefficients corresponding to each pipeline section, the final water quality detection results of each pipeline section are determined.

[0038] In step S203, based on the inter-node correlation coefficients between the nodes of the water quality key detection points corresponding to each pipeline section, the water treatment control strategy and / or the water quality detection control strategy is distributed to the water quality detection sub-controllers corresponding to each pipeline section.

[0039] The technical scheme provided by the embodiments of the present application synchronously acquires the water quality detection results of the feedwater pipeline section, the blowdown pipeline section, the drainage pipeline section and the circulating water pipeline section of the industrial boiler equipment during the operation of the industrial boiler equipment; determines the water quality key detection points, the water quality ordinary detection points and the intra-pipeline-section node correlation coefficients therebetween corresponding to each pipeline section based on the water quality detection results of each pipeline section, and determines the final water quality detection results of each pipeline section based on the intra-pipeline-section node correlation coefficients corresponding to each pipeline section; distributes the water treatment control strategy and / or the water quality detection control strategy to the water quality detection sub-controllers corresponding to each pipeline section based on the inter-node correlation coefficients between the nodes of the water quality key detection points corresponding to each pipeline section, so as to realize comprehensive, accurate and systematic monitoring of the water quality of the feedwater link, the blowdown link, the sewage treatment link and the circulating water link of the industrial boiler equipment during the operation of the industrial boiler equipment, which is conducive to ensuring the normal operation of the industrial boiler and improving the safety and stability performance thereof.

[0040] In some embodiments, based on the water quality detection results of each pipeline section, the water quality key detection points, the water quality ordinary detection points and the intra-pipeline-section node correlation coefficients therebetween corresponding to each pipeline section are determined, and the final water quality detection results of each pipeline section are determined based on the intra-pipeline-section node correlation coefficients corresponding to each pipeline section, including:

[0041] Based on the first water quality detection results of the feedwater pipeline section, the first water quality key detection node and the first water quality ordinary detection node corresponding to the feedwater pipeline section and the first intra-pipeline-section node correlation coefficients therebetween are determined, and the first final water quality detection results of the feedwater pipeline section are determined based on the first intra-pipeline-section node correlation coefficients;

[0042] Based on the second water quality detection results of the blowdown pipeline section, the second water quality key detection node and the second water quality ordinary detection node corresponding to the blowdown pipeline section and the second intra-pipeline-section node correlation coefficients therebetween are determined, and the second final water quality detection results of the blowdown pipeline section are determined based on the second intra-pipeline-section node correlation coefficients;

[0043] Based on the third water quality detection results of the drainage pipeline section, the third water quality key detection node and the third water quality ordinary detection node corresponding to the drainage pipeline section and the third intra-pipeline-section node correlation coefficients therebetween are determined, and the third final water quality detection results of the drainage pipeline section are determined based on the third intra-pipeline-section node correlation coefficients;

[0044] Based on the fourth water quality detection result of the circulating water pipeline section, the fourth water quality key detection node and the fourth water quality detection ordinary node corresponding to the circulating water pipeline section and the fourth correlation coefficient therebetween are determined, and based on the fourth correlation coefficient, the fourth final water quality detection result of the circulating water pipeline section is determined.

[0045] The first water quality key detection node is usually a water quality detection point in the water supply pipeline section where water quality deterioration (water pollution) is most likely to occur.

[0046] The first water quality detection ordinary node is usually a water quality detection point in the water supply pipeline section where water quality deterioration is not likely to occur.

[0047] The first intra-section node correlation coefficient represents the mutual influence relationship of water quality changes between the first water quality key detection node and the first water quality detection ordinary node. Generally, the larger the first intra-section node correlation coefficient, the greater the mutual influence of water quality changes between the first water quality key detection node and the first water quality detection ordinary node, and vice versa. The smaller the first intra-section node correlation coefficient, the smaller the mutual influence of water quality changes between the first water quality key detection node and the first water quality detection ordinary node.

[0048] The second water quality key detection node is usually a water quality detection point in the sewage pipeline section where water quality deterioration (water pollution) is most likely to occur.

[0049] The second water quality detection ordinary node is usually a water quality detection point in the sewage pipeline section where water quality deterioration is not likely to occur.

[0050] The second intra-section node correlation coefficient represents the mutual influence relationship of water quality changes between the second water quality key detection node and the second water quality detection ordinary node. Generally, the larger the second intra-section node correlation coefficient, the greater the mutual influence of water quality changes between the second water quality key detection node and the second water quality detection ordinary node, and vice versa. The smaller the second intra-section node correlation coefficient, the smaller the mutual influence of water quality changes between the second water quality key detection node and the second water quality detection ordinary node.

[0051] The third water quality key detection node is usually a water quality detection point in the drainage pipeline section where water quality deterioration (water pollution) is most likely to occur.

[0052] The third water quality detection ordinary node is usually a water quality detection point in the drainage pipeline section where water quality deterioration is not likely to occur.

[0053] The third intra-road-section node correlation coefficient represents the mutual influence relationship of water quality change between the third water quality key detection node and the third water quality detection normal node. Generally, the greater the third intra-road-section node correlation coefficient, the greater the mutual influence of water quality change between the third water quality key detection node and the third water quality detection normal node, and vice versa, the smaller the third intra-road-section node correlation coefficient, the smaller the mutual influence of water quality change between the third water quality key detection node and the third water quality detection normal node.

[0054] The fourth water quality key detection node is usually a water quality detection point in the circulating water pipeline section that is most prone to water quality deterioration (water pollution).

[0055] The fourth water quality detection normal node is usually a water quality detection point in the circulating water pipeline section that is not prone to water quality deterioration.

[0056] The fourth correlation coefficient represents the mutual influence relationship of water quality change between the fourth water quality key detection node and the fourth water quality detection normal node. Generally, the greater the fourth correlation coefficient, the greater the mutual influence of water quality change between the fourth water quality key detection node and the fourth water quality detection normal node, and vice versa, the smaller the fourth correlation coefficient, the smaller the mutual influence of water quality change between the fourth water quality key detection node and the fourth water quality detection normal node.

[0057] In some embodiments, the water supply pipeline section includes a plurality of water quality detection points, and the first water quality detection result includes a sampling detection result corresponding to each water quality detection point. Based on the first water quality detection result of the water supply pipeline section, the first water quality key detection node and the first water quality detection normal node corresponding to the water supply pipeline section and the first intra-road-section node correlation coefficient between them are determined, including:

[0058] A water quality detection point with a sampling detection result exceeding a preset water quality standard threshold and a maximum difference between the sampling detection result and the preset water quality standard threshold is determined as the first water quality key detection node, and the remaining other water quality detection points are all determined as the first water quality detection normal node;

[0059] A first water quality detection normal node and the first water quality key detection node are determined as a group, and the first intra-road-section node correlation coefficient corresponding to each group is determined.

[0060] The preset water quality standard threshold can be determined according to relevant industrial water detection standards.

[0061] As an example, in combination with Figure 3, assuming that three water quality detection points are arranged in the feedwater pipeline section between the feedwater tank 101 and the industrial boiler equipment 102, which are water quality detection points A1, A2 and A3, wherein the water quality detection point A1 corresponds to the water quality detection sensor a1, the water quality detection point A2 corresponds to the water quality detection sensor a2, and the water quality detection point A3 corresponds to the water quality detection sensor a3. The water quality detection sensor a1 is used to sample and detect the water flowing through the water quality detection point A1 to obtain a sampling detection result 1 and transmit it to the first water quality detection sub-control 105. The water quality detection sensor a2 is used to sample and detect the water flowing through the water quality detection point A2 to obtain a sampling detection result 2 and transmit it to the first water quality detection sub-control 105. The water quality detection sensor a3 is used to sample and detect the water flowing through the water quality detection point A3 to obtain a sampling detection result 3 and transmit it to the first water quality detection sub-control 105. The first water quality detection sub-control 105 reports the collected sampling detection results 1-3 to the water quality detection master control 109. After receiving the sampling detection results 1-3, the water quality detection master control 109 calculates the difference between the sampling detection results 1-3 and the preset water quality standard threshold value, respectively, and determines the water quality detection point with the largest difference between the sampling detection result and the preset water quality standard threshold value as the first water quality key detection node, and determines the remaining other water quality detection points as the first water quality detection normal node. For example, assuming that the sampling detection result 1 is greater than the preset water quality standard threshold value, and the sampling detection results 2 and 3 are less than the preset water quality standard threshold value, the water quality detection point A1 corresponding to the sampling detection result 1 is determined as the first water quality key detection node, and the water quality detection points A2 and A3 corresponding to the sampling detection results 2 and 3 are determined as the first water quality detection normal node.

[0062] Next, the water quality detection point A1 and the water quality detection point A2 are divided into a group 1, and the first intra-segment node correlation coefficient 1 corresponding to the group 1 is determined. The water quality detection point A1 and the water quality detection point A3 are divided into a group 2, and the first intra-segment node correlation coefficient 2 corresponding to the group 2 is determined.

[0063] In some embodiments, determining the first intra-segment node correlation coefficient corresponding to each group comprises:

[0064] For each group, determining a first Euclidean distance value between the first water quality detection normal node and the first water quality key detection node in the group;

[0065] According to the first Euclidean distance value, determining the first intra-segment node correlation coefficient between the first water quality detection normal node and the first water quality key detection node in the group.

[0066] For ease of understanding, continuing with the example above, for group 1, determine the first Euclidean distance value between water quality monitoring point A1 (the first critical water quality monitoring node) and water quality monitoring point A2 (the first ordinary water quality monitoring node). Then, based on the first Euclidean distance value Determine the node correlation coefficients within the first road segment between them. For group 2, determine the first Euclidean distance between water quality monitoring point A1 and water quality monitoring point A3. Then, based on the first Euclidean distance value Determine the node correlation coefficients within the first road segment between them. .

[0067] In some embodiments, determining the intra-segment node correlation coefficient between the first ordinary water quality monitoring node and the first critical water quality monitoring node in the group, based on the first Euclidean distance value, includes:

[0068] If the first Euclidean distance value is less than the first preset distance value, then the node correlation coefficient within the first road segment between the first ordinary water quality detection node and the first key water quality detection node in the group is determined to be 1.

[0069] If the first Euclidean distance value is greater than or equal to the first preset distance value and less than the second preset distance value, then based on the first Euclidean distance value, the first preset distance value, and the second preset distance value, the intra-segment node correlation coefficient between the first ordinary water quality detection node and the first key water quality detection node in the group is determined; wherein, the first preset distance value is less than the second preset distance value;

[0070] If the first Euclidean distance value is greater than or equal to the second preset distance value, then the node correlation coefficient within the first road segment between the first ordinary water quality detection node and the first key water quality detection node in the group is determined to be 0.

[0071] Taking group 1 in the above example as an example, in the first case, if the first Euclidean distance between water quality monitoring point A1 (the first key water quality monitoring node) and water quality monitoring point A2 (the first ordinary water quality monitoring node) is... If the distance is less than the first preset distance value, then the node correlation coefficient within the first road segment between water quality monitoring point A1 and water quality monitoring point A2 is determined. The value is 1. In this case, the distance between water quality monitoring point A1 and water quality monitoring point A2 is very small, indicating that the water quality of these two monitoring points has a large degree of mutual influence in the short term.

[0072] In the second scenario, if the first Euclidean distance between water quality monitoring point A1 (the first critical water quality monitoring node) and water quality monitoring point A2 (the first ordinary water quality monitoring node) is... greater than or equal to the first preset distance value and less than the second preset distance value, the first intra-segment node correlation coefficient between the water quality detection point A1 and the water quality detection point A2 in the first segment is determined based on the first Euclidean distance value, the first preset distance value and the second preset distance value . Specifically, the first intra-segment node correlation coefficient between the water quality detection point A1 and the water quality detection point A2 in the first segment can be calculated according to formula (1) .

[0073] (1)

[0074] In formula (1), represents the first intra-segment node correlation coefficient, represents the first Euclidean distance value, represents the first preset distance value, represents the second preset distance value.

[0075] In this case, the distance between the water quality detection point A1 and the water quality detection point A2 is small, indicating that the water quality of the two detection points will have a certain degree of mutual influence in the short term.

[0076] The third case is that if the first Euclidean distance value between the water quality detection point A1 (the first water quality key detection node) and the water quality detection point A2 (the first water quality ordinary detection node) is greater than or equal to the second preset distance value, the first intra-segment node correlation coefficient between the water quality detection point A1 and the water quality detection point A2 in the first segment can be determined as 0. In this case, the distance between the water quality detection point A1 and the water quality detection point A2 is large, indicating that the mutual influence of the water quality of the two detection points in the short term is very weak and can be ignored.

[0077] In some embodiments, the first final water quality detection result of the water supply pipeline segment is determined based on the first intra-segment node correlation coefficient, including:

[0078] The grouped water quality detection result is determined based on the first intra-segment node correlation coefficient corresponding to each group.

[0079] The grouped water quality detection result corresponding to each group is weighted to obtain the first final water quality detection result of the water supply pipeline segment.

[0080] For ease of understanding, continue to use the above example, please refer to Figure 3 . Taking group 1 as an example, the first case is that if the first intra-segment node correlation coefficient between the water quality detection point A1 (the first water quality key detection node) and the water quality detection point A2 (the first water quality ordinary detection node) is ​​If the value of the node correlation coefficient is 1, then the sampling detection result 1 corresponding to the water quality detection point A1 or the sampling detection result 2 corresponding to the water quality detection point A2 is determined as the group detection result 1 of the group 1.

[0081] In the second case, if the node correlation coefficient of the first road section between the water quality detection point A1 (the first water quality key detection node) and the water quality detection point A2 (the first water quality common detection node) is , then the average of the sampling detection result 1 corresponding to the water quality detection point A1 and the sampling detection result 2 corresponding to the water quality detection point A2 can be determined as the group detection result 1 of the group 1.

[0082] In the third case, if the node correlation coefficient of the first road section between the water quality detection point A1 (the first water quality key detection node) and the water quality detection point A2 (the first water quality common detection node) is 0, then the sampling detection result 1 corresponding to the water quality detection point A1 (the first water quality key detection node) is determined as the group detection result 1 of the group 1.

[0083] It can be understood that for the group 2, the group detection result 2 corresponding to the group 2 can be determined in the above manner, which will not be described here.

[0084] Next, the weight coefficients corresponding to the group 1 and the group 2 are determined as , , wherein , , and .

[0085] In actual application, the weight coefficients and may be determined according to the influence degree of the sampling detection results of different groups on the water quality of the water supply pipeline section. For example, if the influence degree of the sampling detection result of the group 1 on the water quality of the water supply pipeline section is greater than the influence degree of the sampling detection result of the group 2 on the water quality of the water supply pipeline section, then > ; if the influence degree of the sampling detection result of the group 1 on the water quality of the water supply pipeline section is less than the influence degree of the sampling detection result of the group 2 on the water quality of the water supply pipeline section, then < ; and if there is no significant difference between the influence degrees of the sampling detection results of the group 1 and the group 2 on the water quality of the water supply pipeline section, then = .

[0086] Finally, the group detection result of the water quality of the water supply pipeline section is determined according to the weight coefficients , ​The group detection result 1 corresponding to the group 1 and the group detection result 2 corresponding to the group 2 are weighted to obtain a first final water quality detection result of the water supply pipeline section.

[0087] It can be understood that, with reference to the above embodiments, the second water quality key detection node and the second water quality detection normal node in the sewage pipeline section and the second intra-section node correlation coefficient therebetween are determined based on the second water quality detection result, and the second final water quality detection result of the sewage pipeline section is determined based on the second intra-section node correlation coefficient; the third water quality key detection node and the third water quality detection normal node in the drainage pipeline section and the third intra-section node correlation coefficient therebetween are determined based on the third water quality detection result, and the third final water quality detection result of the drainage pipeline section is determined based on the third intra-section node correlation coefficient; the fourth water quality key detection node and the fourth water quality detection normal node in the circulating water pipeline section and the fourth correlation coefficient therebetween are determined based on the fourth water quality detection result, and the fourth final water quality detection result of the circulating water pipeline section is determined based on the fourth correlation coefficient, which will not be described herein.

[0088] In some embodiments, the water treatment control strategy and / or the water quality detection control strategy is distributed to the water quality detection sub-control corresponding to each pipeline section based on the inter-section node correlation coefficient between the water quality key detection points of the corresponding pipeline section, including:

[0089] determining the inter-section node correlation coefficient between the water quality key detection points of the corresponding pipeline section;

[0090] distributing the water treatment control strategy and / or the water quality detection control strategy to the first water quality detection sub-control, the second water quality detection sub-control, the third water quality detection sub-control and the fourth water quality detection sub-control based on the inter-section node correlation coefficient;

[0091] The water treatment control strategy includes at least one of water flow, water flow rate, water quality standard threshold or water treatment mode for the water supply pipeline section, the sewage pipeline section, the drainage pipeline section and the circulating water pipeline section; and the water quality detection control strategy includes the number of water quality detection points and the number of water quality detection times for the water supply pipeline section, the sewage pipeline section, the drainage pipeline section and the circulating water pipeline section.

[0092] As an example, assuming that the first water quality key detection node of the water supply pipeline section is water quality detection point A1, the second water quality key detection node of the sewage pipeline section is water quality detection point B1, the third water quality key detection node of the drainage pipeline section is water quality detection point C3, and the fourth water quality key detection node of the circulating water pipeline section is D2, then the inter-section node correlation coefficient between A1 and B1 is calculated as the inter-section node correlation coefficient between A1 and C3 the inter-segment node correlation between A1 and D2 the inter-segment node correlation between B1 and C3 the inter-segment node correlation between B1 and D2 the inter-segment node correlation between C3 and D2 .

[0093] The inter-segment node correlation can be determined in the same way as the intra-segment node correlation between the first water quality key detection node and the first water quality detection normal node in the water supply pipe segment ~ which will not be repeated here.

[0094] Next, the inter-segment node correlations , , are compared to determine the maximum correlation therefrom, and the water treatment control strategy for the water supply pipe segment between the water supply tank 101 and the industrial boiler equipment 102 is determined according to the maximum correlation. For example, assuming that the inter-segment node correlations , , are arranged in the following order: the maximum correlation therefrom is , which indicates that the water quality detection point A1 in the water supply pipe segment has a greater impact on the water quality of the water quality detection point B1 in the sewage pipe segment. Based on this, at least one of the water flow, the water flow rate, the water quality standard threshold, or the water treatment method (such as adjusting the hardness, pH value, alkalinity, etc. of the water flow in the water supply pipe segment by adding chemical agents, etc.) in the water supply pipe segment can be adjusted to reduce its impact on the water quality of the water quality detection point B1, thereby improving the water quality of the water quality detection point B1.

[0095] Similarly, the inter-segment node correlations , , are compared to determine the maximum correlation therefrom, and the water treatment control strategy for the sewage pipe segment between the industrial boiler equipment 102 and the sewage tank 103 is determined according to the maximum correlation (i.e. adjusting at least one of the water flow, the water flow rate, the water quality standard threshold, or the water treatment method in the sewage pipe segment).

[0096] The inter-segment node correlations , , The magnitude of the correlation coefficient is used to determine the maximum correlation coefficient, and a water treatment control strategy (i.e., adjusting at least one of the following: water flow rate, water velocity, water quality standard threshold, or water treatment method) is determined based on the maximum correlation coefficient for the drainage pipeline section between sewage tank 103 and circulating water tank 104.

[0097] By comparing the node correlation coefficients between road segments , , The magnitude of the correlation coefficient is used to determine the maximum correlation coefficient, and a water treatment control strategy is determined based on the maximum correlation coefficient for the circulating water pipeline section between the circulating water tank 104 and the industrial boiler equipment 102 (specifically, it may be adjusting at least one of the following: water flow rate, water velocity, water quality standard threshold, or water treatment method of the circulating water pipeline section).

[0098] The above implementation method fully considers the degree of mutual influence between the water quality of each key water quality detection node in the water supply pipeline, sewage pipeline, drainage pipeline, and circulating water pipeline. It can systematically, comprehensively, and accurately monitor the water quality of the water supply, sewage discharge, wastewater treatment, and circulating water links of industrial boiler equipment during operation from a macroscopic perspective. This is conducive to further ensuring the normal operation of industrial boilers and improving their safety and stability performance.

[0099] To facilitate understanding, we will continue with the above example and compare the node correlation coefficients between road segments. , , The magnitude of the correlation coefficient between the two is used to determine the maximum correlation coefficient, and the water quality monitoring and control strategy for the water supply pipeline section between the water supply tank 101 and the industrial boiler equipment 102 is determined based on the maximum correlation coefficient (i.e., increasing / decreasing the number of water quality monitoring points and the number of water quality monitoring times in the water supply management section).

[0100] By comparing the node correlation coefficients between road segments , , The magnitude of the correlation coefficient between the two is used to determine the maximum correlation coefficient, and the water quality monitoring and control strategy for the sewage pipeline section between industrial boiler equipment 102 and sewage tank 103 is determined based on the maximum correlation coefficient (i.e., increasing / decreasing the number of water quality monitoring points and the number of water quality monitoring times in the sewage pipeline section).

[0101] By comparing the node correlation coefficients between road segments , , between the sizes of the correlation coefficients to determine the maximum correlation coefficient, and determine the water quality detection regulation strategy (i.e., increase / decrease the number of water quality detection points and the number of water quality detection times in the drainage pipeline section) according to the maximum correlation coefficient.

[0102] between the sizes of the correlation coefficients to determine the maximum correlation coefficient, and determine the water quality detection regulation strategy (i.e., increase / decrease the number of water quality detection points and the number of water quality detection times in the drainage pipeline section) according to the maximum correlation coefficient. 、 、 between the sizes of the correlation coefficients to determine the maximum correlation coefficient, and determine the water quality detection regulation strategy (i.e., increase / decrease the number of water quality detection points and the number of water quality detection times in the drainage pipeline section) according to the maximum correlation coefficient.

[0103] The above-mentioned embodiments fully consider the degree of mutual influence of water quality among the key water quality detection nodes in the water supply pipeline section, the sewage pipeline section, the drainage pipeline section, and the circulating water pipeline section, and increase / decrease the number of water quality detection points and the number of water quality detection times in each pipeline section according to the degree of mutual influence of water quality among the key water quality detection nodes, so as to improve the efficiency and cost of water quality detection under the premise of ensuring the accuracy of the water quality detection results of each pipeline section.
