Obtain the traceability point possibility between the monitoring stations to be investigated and the traceability monitoring station at the current collection moment. Combine the distance between the polluted upstream monitoring station and the polluted monitoring station, and the river pollutant concentration of the monitoring stations to be investigated at the current collection moment to determine the pollution source possibility between the polluted upstream monitoring station and the polluted monitoring station at the current collection moment. Based on the pollution source possibility, realize the traceability management of environmental monitoring based on the blockchain.

[0005] Further, the specific method for identifying the abnormal moment according to the value of the river pollutant concentration includes: When the collected river pollutant concentration is greater than the standard value of the river pollutant concentration, record the collection moment of the river pollutant concentration as the abnormal moment.

[0006] Further, the determination method of the polluted monitoring station at the current collection moment is: Record the automated monitoring station corresponding to the maximum value among all the average deposition rates of pollutants at the current collection moment as the polluted monitoring station at the current collection moment.

Specifically, first, determine the automated monitoring station with the most serious pollution degree at the current collection moment, that is, the pollution monitoring station, according to the average growth rate of the river pollutant concentration of each automated monitoring station; then, when the pollution monitoring station at the current collection moment is downstream of the water environment abnormal location, the river pollutant concentration at the water environment abnormal location is relatively stable. Since the pollutants at the water environment abnormal location will diffuse downstream, the river pollutant concentration at the positions of each automated monitoring station downstream of the water environment abnormal location will also rise steadily, and determine the tracing source monitoring station, which is an important reference in the subsequent process of tracing river pollutants; finally, determine the pollution source possibility between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment according to the distance between the pollution upstream monitoring station and the pollution monitoring station, and the river pollutant concentration of the monitoring station to be investigated at the current collection moment.

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0015] Figure 1 It is a schematic flow chart of an environmental monitoring traceability management method provided by an embodiment of the present invention; Figure 2 It is a flowchart for obtaining a pollution monitoring station provided by an embodiment of the present invention. Detailed Embodiments

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Please refer to Figure 1 , which shows a flowchart of an environmental monitoring traceability management method provided by an embodiment of the present invention. The method includes the following steps: Step S001: Collect the river pollutant concentrations of all automated monitoring stations in the river, the distances between all automated monitoring stations, and the upstream and downstream relationships between different automated monitoring stations. Identify the abnormal moments according to the values of the river pollutant concentrations, and continue to collect the river pollutant concentrations of all automated monitoring stations in the river from the abnormal moments until the current collection moment.

[0018] In the river where water environment monitoring is required, automated monitoring stations are set along the flow direction of the river, and automated equipment in the automated monitoring stations is used to collect the river pollutant concentrations. The time interval for each automated monitoring station to collect the river pollutant concentration is 2 hours. When the collected river pollutant concentration is greater than the standard value of the river pollutant concentration, the collection moment of the river pollutant concentration is recorded as the abnormal moment. From the abnormal moment, the river pollutant concentration is collected every 5 minutes at each automated monitoring station.

[0019] In this implementation, the time intervals for collecting river pollutant concentrations before and after the abnormal moment are 2 hours and 5 minutes respectively; in this embodiment, experts in the field of river pollution set the number of automated monitoring stations and the specific locations of automated monitoring stations along the flow direction of the river according to the specific needs of the river for water environment monitoring; the concentration of river pollutants can use the main pollution indicators in water, such as dissolved oxygen, chemical oxygen demand, total phosphorus, etc., and the river pollutant concentration collected in this embodiment is total phosphorus; the standard value of river pollutant concentration is obtained according to the "Surface Water Environmental Quality Standard" (GB 3838-2002), which is proposed and managed by the Science and Technology Standards Department of the State Environmental Protection Administration. In the actual application process, as other implementation methods, the implementer can decide the time interval for collecting river pollutant concentrations before and after the abnormal moment according to the actual situation, and can also decide the type of river pollutant concentration according to the actual situation, and this application does not make special restrictions.

[0020] It can be understood that the abnormal moment is the moment when water environment abnormalities occur in the river that needs to be monitored, that is, the concentration of river pollutants collected by an automated monitoring station exceeds the standard. At this time, illegal discharge or leakage of pollutants occurs at the location of the automated monitoring station or upstream of the automated monitoring station. Starting from the abnormal moment, it is necessary to analyze the concentration of river pollutants collected by all automated monitoring stations at each collection moment, and record the latest collection moment among all collection moments after the abnormal moment as the current collection moment.

[0021] Based on the bird's-eye view of the river area, the distances between all automated monitoring stations set up in the river for water environment monitoring are obtained, and the upstream and downstream relationships between different automated monitoring stations are marked.

[0022] It can be understood that the distance between the automated monitoring stations is the length of the water body between the automated monitoring stations in the river for water environment monitoring, and is not the straight-line distance between the automated monitoring stations.

[0023] At this point, the distances between all automated monitoring stations, the upstream and downstream relationships between different automated monitoring stations, and the river pollutant concentrations of all automated monitoring stations at all collection times from the abnormal moment to the current collection moment are obtained.

[0024] Step S002: Based on the time interval between the current collection moment and the abnormal moment and the difference in the river pollutant concentration of the same automated monitoring station, obtain the average pollutant deposition rate of the same automated monitoring station at the current collection moment, and determine the pollution monitoring station at the current collection moment. According to the upstream and downstream relationship between different automated monitoring stations, determine the upstream pollution monitoring station at the current collection moment. Based on the average pollutant deposition rates of the upstream pollution monitoring station and the pollution monitoring station at the current collection moment, and the time interval between the current collection moment and the abnormal moment, determine the traceability monitoring station.

[0025] The abnormal moment is the moment when water environment anomalies occur in the river that requires water environment monitoring, that is, the river pollutant concentration collected by a certain automated monitoring station exceeds the standard. At this time, illegal discharge or leakage of pollutants occurs at or upstream of the location of the automated monitoring station. It can be understood that when illegal discharge or leakage of pollutants occurs at the location of the automated monitoring station, the river pollutant concentration collected at the location of the automated monitoring station is relatively high, so the river pollutant concentration collected by the automated monitoring station exceeds the standard. It is also possible that illegal discharge or leakage of pollutants occurs upstream of the location of the automated monitoring station, but the speed of illegal discharge or leakage of pollutants is slow. Therefore, the location of pollution is identified and water environment anomalies are detected. However, the pollutants diffuse with the water flow and are deposited at a certain position downstream of the water environment anomaly location. When the deposition reaches a certain level, water environment anomalies are detected at the deposition position. Therefore, the average growth rate of the river pollutant concentration at the location where pollutants are deposited is relatively high.

[0026] Based on the time interval between the current collection moment and the abnormal moment and the difference in the river pollutant concentration of the same automated monitoring station, obtain the average pollutant deposition rate of the same automated monitoring station at the current collection moment.

[0027] Record the difference in the river pollutant concentration of the same automated monitoring station between the current collection moment and the abnormal moment as the pollution increase value of the same automated monitoring station at the current collection moment; record the time interval between the current collection moment and the abnormal moment as the pollution time at the current collection moment; record the ratio of the pollution increase value of the same automated monitoring station at the current collection moment to the pollution time at the current collection moment as the average pollutant deposition rate of the same automated monitoring station at the current collection moment.

[0028] Record the automated monitoring station corresponding to the maximum value among all the average pollutant deposition rates at the current collection moment as the pollution monitoring station at the current collection moment.

[0029] The pollution monitoring station at the current collection moment is the automated monitoring station with the most serious pollutant deposition at the current collection moment.

[0030] The flowchart for obtaining the pollution monitoring station is as Figure 2 shown.

[0031] Furthermore, it is necessary to identify whether the pollution monitoring station at the current collection moment is at the location of abnormal water environment or downstream of the location of abnormal water environment. When the pollution monitoring station is downstream of the location of abnormal water environment, it is necessary to further and timely determine the location of abnormal water environment upstream of the pollution monitoring station.

[0032] All the automated monitoring stations upstream of the pollution monitoring station and the pollution monitoring station itself are recorded as the pollution upstream monitoring stations at the current collection moment.

[0033] When the pollution monitoring station at the current collection moment is downstream of the location of abnormal water environment, the river pollutant concentration at the location of abnormal water environment is relatively stable, and the pollutants at the location of abnormal water environment will diffuse downstream, and the river pollutant concentration at the locations of each automated monitoring station downstream of the location of abnormal water environment will also increase steadily.

[0034] According to the average deposition rate of pollutants of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment, and the time interval between the current collection moment and the abnormal moment, determine the possibility of the traceability point of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment.

[0035] Preferably, as an embodiment of the present application, the ratio of the average deposition rate of pollutants of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment is recorded as the first ratio of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment, and the product of the first ratio of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment and the pollution time at the current collection moment is recorded as the possibility of the traceability point of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment.

[0036] It can be understood that there may be one or more pollution upstream monitoring stations at the current collection moment. For any pollution upstream monitoring station at the current collection moment, there is a corresponding possibility of the traceability point of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment.

[0037] When the pollution time at the current collection moment is larger, the duration of the occurrence of illegal discharge or leakage of pollutants is longer. At the same time, when the first ratio of the pollution upstream monitoring station and the pollution monitoring station at the current collection moment is larger, the deposition rate of pollutants at the pollution monitoring station relative to the pollution upstream monitoring station is larger, and the pollutant deposition at the location of the pollution monitoring station is closer to the saturation state, and the possibility of illegal discharge or leakage of pollutants at the pollution upstream monitoring station is greater.

[0038] The pollution upstream monitoring station corresponding to the maximum value of the traceability point possibility is denoted as the traceability monitoring station.

[0039] It should be noted that the pollution monitoring station itself is also denoted as the pollution upstream monitoring station at the current collection moment, which is used to calculate the traceability point possibility between the pollution monitoring station at the current collection moment and itself, ensuring the accuracy of the selected traceability monitoring station.

[0040] Thus, the traceability monitoring station is determined.

[0041] Step S003: Denote all the upstream automated monitoring stations of the traceability monitoring station as the monitoring stations to be inspected, obtain the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment, combine the distance between the pollution upstream monitoring station and the pollution monitoring station, and the river pollutant concentration of the monitoring stations to be inspected at the current collection moment, determine the pollution source possibility between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment, and realize the blockchain-based environmental monitoring traceability management according to the pollution source possibility.

[0042] Denote all the upstream automated monitoring stations of the traceability monitoring station as the monitoring stations to be inspected.

[0043] According to the method of obtaining the traceability point possibility between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment, calculate the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment. Specifically, the method for obtaining the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment is as follows: Determine the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment according to the average sedimentation rate of pollutants between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment, and the time interval between the current collection moment and the abnormal moment.

[0044] Denote the ratio of the average sedimentation rate of pollutants between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment as the first ratio between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment, and denote the product of the first ratio between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment and the pollution time at the current collection moment as the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment.

[0045] Denote the ratio of the traceability point possibility between the monitoring stations to be inspected and the traceability monitoring station at the current collection moment and the corresponding distance as the first ratio between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment, and denote the normalized value of the product of the river pollutant concentration of the monitoring stations to be inspected at the current collection moment and the first ratio between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment as the pollution source possibility between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment.

[0046] It should be noted that in this embodiment, the Z-Score standard normalization method is used to calculate the normalized value. In actual application, the implementer can use other methods of existing technologies such as the maximum-minimum normalization method, sigmoid function, etc. to calculate the normalized value, which is not limited here.

[0047] When the distance between the pollution upstream monitoring station and the pollution monitoring station is larger, the referenceability of the influence of the pollution upstream monitoring station on the pollutant concentration of the pollution monitoring station is smaller. At the same time, when the river pollutant concentration of the monitoring station to be investigated at the current collection moment is larger and the possibility of the traceability point between the monitoring station to be investigated at the current collection moment and the traceability monitoring station is larger, the possibility that the pollution upstream monitoring station is the source of pollutant leakage is larger. At this time, the possibility of the pollution source between the pollution upstream monitoring station and the pollution monitoring station at the current collection moment is larger.

[0048] Thus, at the current collection moment, the possibility of the pollution source between the pollution monitoring station and any pollution upstream monitoring station can be obtained.

[0049] The pollution upstream monitoring station corresponding to the maximum value of the pollution source possibility is denoted as the water pollution location, which is the accurate location of water pollution traced by the environmental monitoring of the water pollution location.

[0050] Thus, the environmental monitoring traceability management based on the blockchain is realized.

[0051] Based on the same inventive concept as the above method, an embodiment of the present invention further provides an environmental monitoring traceability management system, including a memory, a processor, and a computer program stored in the memory and running on the processor. When the processor executes the computer program, the steps of any one of the above methods for an environmental monitoring traceability management method are implemented.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present invention shall be included in the protection scope of the present invention.
