[0001] The present application relates to the technical field of water environment pollution, and specifically to an early warning method, device, system and computer-readable storage medium for water quality monitoring. Background Art

[0002] At present, water quality monitoring early warning is mainly carried out by comparing the data of a single water quality monitoring project with the limit values in the water quality standard classification in "GB3838-2002 Surface Water Environmental Quality Standard".

This will cause trouble for the environmental supervision department, and it will not be able to distinguish abnormal water quality mutation events, nor can it realize water quality mutation early warning, resulting in the water quality monitoring results often failing to reflect the actual problems in a timely and accurate manner.

[0029] See also Figure 3 , is a flow chart of an early warning method for water quality monitoring provided by an embodiment of the present invention, the method comprising:

[0030] S301: Obtain concentration information of multiple related factors in water quality monitoring parameters.

[0031] The water quality monitoring parameters refer to various characteristic indicators used to characterize the quality and changing trends of water environment, such as characteristic indicators of various substances contained in water. The related factors are single factors used to characterize the quality of water environment in water quality monitoring parameters, which can be physical and / or chemical and / or biological single factors, such as chemical oxygen demand, volatile phenols, pH, dissolved oxygen, heavy metals, fluorides, petroleum, sulfides, organic matter, anionic surfactants, ammonia nitrogen, permanganate index, total phosphorus, total nitrogen, or even the number of bacteria. The concentration information refers to the content of a single related factor in the water environment. The obtaining of concentration information of multiple relevant factors in the water quality monitoring parameters may refer to the water quality analyzer obtaining the concentration information of relevant factors in the water environment of the monitored location. Optionally, the water quality analyzer includes: a chemical oxygen demand water quality analyzer, a volatile phenol water quality analyzer, a pH water quality analyzer, a dissolved oxygen water quality analyzer, a heavy metal water quality analyzer, a petroleum water quality analyzer, a sulfide water quality analyzer, an organic matter water quality analyzer, a permanganate index water quality analyzer, an ammonia nitrogen water quality analyzer, a total phosphorus water quality analyzer, and a total nitrogen water quality analyzer. One or more of the following.

[0032] S302: Calculate the concentration information of the plurality of related factors according to different preset concentration mean algorithms to obtain corresponding calculation results, and compare the corresponding calculation results with the water quality mutation rule to determine the current warning level.

[0033] The preset different concentration mean algorithms are concentration mean algorithms corresponding to each correlation factor, which are pre-set based on the characteristics of multiple correlation factors. The concentration mean is the average value of the concentration information corresponding to the correlation factor at multiple different time points within a specified time period. For example, if the correlation factor is dissolved oxygen, the specified time period is one day, and the different time points are each integer time points, then the concentration mean can be the average value of the concentration information corresponding to the twenty-four time points of the dissolved oxygen on that day. The concentration mean algorithm is a calculation formula for calculating the concentration mean. The water quality mutation rule is the change condition in which the concentration information of multiple correlation factors in the water quality monitoring parameters exceeds the preset threshold value within a unit time. It can be a mutation rule divided into multiple levels according to different preset threshold values. The said performing operations on the concentration information of the plurality of related factors according to the preset different concentration average algorithms to obtain the corresponding operation results can be: the processor performs operations on the concentration information of the plurality of related factors according to the preset different concentration average algorithms to obtain the corresponding operation results. For example, the processor determines the average value of the concentration information of total phosphorus on the day according to the concentration information corresponding to the twenty-four time points of total phosphorus on the day, the processor determines the average value of the concentration information of total nitrogen on the day according to the concentration information corresponding to the twenty-four time points of total nitrogen on the day, the processor determines the average value of the concentration information of permanganate index on the day according to the concentration information corresponding to the twenty-four time points of permanganate index on the day, the processor determines the average value of the concentration information of pH value on the day according to the negative logarithm of the arithmetic mean of the hydrogen ion concentration of pH value corresponding to the twenty-four time points of the day, and so on, until the average values of the concentration information of all related factors are calculated. The determining of the current warning level by comparing the respective corresponding operation results with the water quality mutation rule may be that the processor determines the current warning level by comparing the respective corresponding operation results with the water quality mutation rule; for example, the processor compares the average values of the concentration information of the above-mentioned total phosphorus, total nitrogen, permanganate index, pH value and other related factors with the water quality mutation rule; if the result after comparison is consistent with the first preset mutation rule, the current warning level is determined to be level one; if the result after comparison is consistent with the second preset mutation rule, the current warning level is determined to be level two.

[0034] S303: issuing corresponding warning information according to the current warning level.

[0035] The warning information is an emergency signal sent to relevant departments to report dangerous situations. The warning information corresponding to the current warning level can be sent by the water quality warning center according to the current warning level. For example, if the current warning level is level three, the water quality warning center will issue a text warning message indicating that the water quality exceeds the standard; if the current warning level is level two, the water quality warning center will issue a yellow signal light and a voice broadcast warning message; if the current warning level is level one, the water quality warning center will issue a red signal light and an emergency alarm sound warning message.

[0036] The early warning method for water quality monitoring provided in the embodiment of the present application automatically warns of water quality monitoring by using concentration information of multiple related factors and setting water quality mutation rules, so that early warning information of corresponding levels can be issued in a timely manner according to different mutation situations of water quality monitoring parameters. For example, when the water quality mutation rate is detected to be small based on the concentration information calculation results of multiple related factors combined with the water quality mutation rules, the current early warning level is determined to be level three, and corresponding early warning information is issued based on the current early warning level being level three; when the water quality mutation rate is detected to be large, the current early warning level is determined to be level one, and corresponding early warning information is issued based on the current early warning level being level one. Therefore, the embodiment of the present application makes it easy to distinguish changes in water quality and improves the accuracy of early warning.

[0037] In another embodiment of the present application, the obtaining of concentration information of multiple related factors in water quality monitoring parameters includes: periodically obtaining the concentration information of pH value and dissolved oxygen in water quality monitoring parameters with a first preset time length as a counting unit, and periodically obtaining the concentration information of at least one related factor other than the pH value and the dissolved oxygen in water quality monitoring parameters with a second preset time length as a counting unit; generating a parameter table with integer time points corresponding to the concentration information of pH value, dissolved oxygen and at least one related factor other than the pH value and the dissolved oxygen with a preset time period as a tabulation unit; wherein the preset time period is an integer multiple of the first preset time length and the second preset time length.

[0038] The first preset duration and the second preset duration can be time periods pre-set in the system, for example, 10 minutes, 1 hour, half a day, etc. The preset time period can also be a time period pre-set in the system, for example, 1 day, a week, etc., wherein the preset time period is an integer multiple of the first preset duration and the second preset duration. The periodic acquisition of pH value and dissolved oxygen concentration information in water quality monitoring parameters with the first preset duration as the counting unit can refer to multiple sets of water quality analyzers periodically acquiring pH value and dissolved oxygen concentration information in water quality monitoring parameters with the first preset duration as the counting unit, for example, the pH sensor periodically acquires pH value in water quality monitoring parameters with the counting unit of each hour, and the dissolved oxygen sensor periodically acquires dissolved oxygen concentration information in water quality monitoring parameters with the counting unit of each hour. The periodic acquisition of the concentration information of at least one relevant factor in the water quality monitoring parameters other than the pH value and the dissolved oxygen using the second preset time as the counting unit may refer to multiple sets of water quality analyzers periodically acquiring the concentration information of at least one relevant factor in the water quality monitoring parameters other than the pH value and the dissolved oxygen using the second preset time as the counting unit, for example, a permanganate index water quality analyzer periodically acquires the concentration information of the permanganate index in the water quality monitoring parameters using every four hours as the counting unit, an ammonia nitrogen water quality analyzer periodically acquires the concentration information of the ammonia nitrogen in the water quality monitoring parameters using every four hours as the counting unit, etc. The parameter table corresponding to the concentration information of pH value, dissolved oxygen, permanganate index, ammonia nitrogen, total phosphorus and total nitrogen at integer time points respectively with a preset time period as a tabulation unit can refer to a parameter table corresponding to the concentration information of pH value, dissolved oxygen and at least one related factor other than the pH value and the dissolved oxygen at integer time points respectively with a preset time period as a tabulation unit. For example, the Sink node in the monitoring device generates concentration information of pH value and concentration information of dissolved oxygen corresponding to 24 time points respectively with a daily tabulation unit, and generates concentration information of permanganate index, ammonia nitrogen, total phosphorus and total nitrogen corresponding to every four time points respectively with a daily tabulation unit. In this way, the concentration information of multiple related factors in the collected water quality monitoring parameters is displayed to the monitoring manager in the form of a table, which is conducive to the filing management of the database and the timely viewing of the monitoring manager.

[0039] In another embodiment of the present application, the early warning method for water quality monitoring also includes: obtaining a target parameter analysis instruction based on a parameter display page, and switching to a chart display page showing the change trend of the target parameter according to the target parameter analysis instruction; and / or, based on the parameter display page, marking and displaying abnormal parameters in the parameter table in the form of explicit annotations.

[0040] The target parameter refers to the concentration information of a specified correlation factor in the water quality monitoring parameters. The processor obtaining a target parameter analysis instruction based on a parameter display page and switching to a graph display page displaying the target parameter's changing trend based on the target parameter analysis instruction may refer to the processor obtaining a target parameter analysis instruction based on the parameter display page and switching to a graph display page displaying the target parameter's changing trend based on the target parameter analysis instruction. For example, the processor may obtain an analysis instruction for dissolved oxygen concentration information based on a parameter display page for multiple correlation factors generated with a daily tabulation period, and switch to a graph display page displaying the changing trend of the dissolved oxygen concentration information based on the analysis instruction for the dissolved oxygen concentration information. The processor may explicitly mark and display abnormal parameters in the parameter table based on the parameter display page. For example, the processor may explicitly mark and display abnormal parameters in the parameter table based on the parameter display page for multiple correlation factors generated with a daily tabulation period. Abnormal parameters exceeding one standard are marked in yellow, and abnormal parameters exceeding two or more standards are marked in red. In this way, by viewing the target parameters in the parameter table according to the target parameter analysis instructions, and marking and displaying abnormal parameters in the parameter table in the form of explicit annotations, it is beneficial for supervisory managers to clearly and intuitively view the concentration information of target-related factors in water quality monitoring parameters, and enhance the management enthusiasm of supervisory managers.

[0041] In another embodiment of the present application, issuing corresponding warning information according to the current warning level includes: according to the current warning level, sending warning information to a water quality monitoring management terminal that matches the warning level.

[0042] Here, the warning level can be divided into multiple levels according to the degree of sudden change in the water environment pollution. Accordingly, each warning level corresponds to a water quality monitoring and management terminal with different permissions. Each water quality monitoring and management terminal will adopt exclusive treatment measures within the scope of its permissions. At the same time, each water quality monitoring and management terminal uses different alarm information. The sending of warning information to the water quality monitoring and management terminal that matches the warning level according to the current warning level can be: the water quality warning center determines the water quality monitoring and management terminal that matches the current warning level according to the current warning level, and sends the warning information that matches the current warning level to the matching water quality monitoring and management terminal. For example, the water quality warning center determines that the matching water quality monitoring and management terminal is the management terminal of the water quality monitoring operation and maintenance company based on the current warning level of level three, and sends the corresponding warning prompt to the management terminal of the operation and maintenance company; for another example, the water quality warning center determines that the matching water quality monitoring and management terminal is the management terminal of the ecological environment administrative department of the site location based on the current warning level of level one, and sends the corresponding warning prompt to the terminal of the local ecological environment administrative department; and so on. Accordingly, after receiving the warning information, the matching water quality monitoring and management terminal will take exclusive treatment measures within the scope of its permissions. In this way, according to the current warning level, warning information is sent to the water quality monitoring and management terminal that matches the warning level. According to the severity of the water environment pollution, the corresponding water quality monitoring and management terminal can be reminded in time to adopt exclusive response measures within its authority to deal with it, which is conducive to the early remediation of water environment pollution.

[0043] In another embodiment of the present application, the concentration information of the plurality of related factors is calculated according to different preset concentration mean algorithms to obtain corresponding calculation results, and the corresponding calculation results are comprehensively compared with the water quality mutation rules to determine the current warning level, including: obtaining multiple average values of the corresponding dissolved oxygen determined at time periods every third preset time according to the parameter table; wherein two adjacent time periods partially overlap; and obtaining the average value of the corresponding dissolved oxygen in the preset historical time period before the current time; if the adjacent set multiple average values of the corresponding dissolved oxygen in the third preset time period are lower than the average value of the dissolved oxygen in the preset historical time period by more than a first set threshold, and are lower than the concentration limit of the corresponding dissolved oxygen in the surface water Class V standard, or are two levels lower than the water quality category corresponding to the preset historical time period; and / or, obtaining the corresponding dissolved oxygen at time periods every third preset time according to the parameter table The third preset time length is multiple average values of the corresponding pH values determined by the time period; wherein, two adjacent time periods partially overlap; if the adjacent set multiple pH values are less than 5.5 or greater than 10.5; and / or, according to the parameter table, the concentration information of at least one related factor other than the pH value and the dissolved oxygen is obtained, and the average value of the concentration information of at least one related factor other than the pH value and the dissolved oxygen in the preset historical time period before the current time is obtained; if the adjacent set concentration information of at least one related factor other than the pH value and the dissolved oxygen is greater than or equal to the first set multiple of the average value of the concentration information of the corresponding factor in the preset historical time period, and is lower than the concentration limit of the corresponding factor in the surface water Class V standard, or the water quality category corresponding to the average value of the preset historical time period is reduced by two levels; determine that the current warning level is a level one warning.

[0044] Here, the third preset duration and the preset historical period are preset time periods, for example, half an hour, one hour, four hours, three days, etc. The partial overlap between the two adjacent time periods may refer to the presence of multiple identical moments between the two time periods. For example, the third preset duration is 4 hours, and the two adjacent time periods are 0-3 o'clock and 1-4 o'clock respectively, then the time period of 2-5 o'clock is the overlapping part between the two adjacent time periods. The set multiple average values may be the number of preset average values, for example, three, five, etc. The set threshold is a preset maximum limit. The acquisition of the corresponding multiple average values of dissolved oxygen determined at intervals of the third preset duration according to the parameter table may refer to: the processor acquires the corresponding multiple average values of dissolved oxygen determined at intervals of the third preset duration according to the parameter table, for example, refer to Figure 4The processor obtains several average values of corresponding dissolved oxygen determined at four-hour intervals based on a table of water quality monitoring parameters recorded within a twenty-four-hour period, wherein there is a three-hour overlap between two adjacent time periods.
