[0002] Quality control in the process of water quality monitoring is a key link to ensure that the monitoring data is accurate and reliable. At present, the commonly used automatic quality control method for online monitoring systems is mainly to achieve automatic quality control through online water quality quality controllers, namely water quality monitors. Specifically, in a fixed detection cycle, standard samples are used to perform detection using online water quality quality controllers to obtain actual measurement values, and the actual measurement values ​​are compared and analyzed with the standard values ​​to evaluate the stability and accuracy of the instrument, and then the parameters are recalibrated when the instrument is abnormal so that the instrument can be used normally.

[0003] This quality control method is carried out in a fixed testing cycle and may not be able to detect anomalies or deviations in the testing process in a timely manner.

[0064] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, a person skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by the patent law as long as they are within the scope of the present application.

[0065] It should be noted that in the optional embodiments of the present application, the object information and other related data involved, when the embodiments in the present application are applied to specific products or technologies, need to obtain the permission or consent of the object, and the collection, use and processing of the relevant data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

If sensitive information is involved, the separate consent of the information subject needs to be obtained. The embodiments also need to be implemented with the authorization and consent of the object.

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0067] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0068] Quality control in the water quality monitoring process is a key link to ensure that the monitoring data is accurate and reliable. At present, the commonly used automatic quality control method for online monitoring systems is mainly to achieve automatic quality control through online water quality quality controllers, namely water quality monitors. Specifically, in a fixed detection cycle, standard samples are used to detect using online water quality quality controllers to obtain actual measurement values, and the actual measurement values ​​are compared and analyzed with the standard values ​​to evaluate the stability and accuracy of the instrument, and then the parameters are recalibrated when the instrument is abnormal so that the instrument can be used normally. This quality control method is carried out in a fixed detection cycle, and may not be able to detect abnormalities or deviations in the detection process in time. If there are system errors or instrument failures in the detection process, these problems may be ignored in detection outside the fixed cycle, thereby affecting the accuracy and reliability of the test results.

[0069] Moreover, during the water quality monitoring process, quality control verification is basically triggered and started at a fixed time or frequency. When the water quality fluctuates, quality control measures are not added in time, and the effectiveness and representativeness of the current water sample cannot be verified. Most quality control facilities only provide quality control verification samples, and cannot verify the effectiveness of the provided quality control samples. Existing quality control instruments only meet the needs of on-site operation, and do not have the functions of remotely setting the concentration of the verification sample and remotely starting the verification. They cannot meet the functions of remote control and dynamic sample matching, and cannot reflect the randomness of standard sample verification. Specifically, the structure of some quality control instruments is single, and the fixed concentration quality control verification mode can only be achieved by adding multi-way exhaust valves to expand the channels such as standard solution verification, zero point verification, span verification and blind sample verification. The quality control method is achieved by switching different channels, and the standard sample concentration is single and fixed. For the situation where water quality mutations often occur in some sections, when the verification concentration needs to be adjusted in time, it is necessary to go to the site to replace the standard solution, which is also time-consuming and laborious. It is not possible to automatically adjust the concentration of the standard sample according to the fluctuation of the water sample, and it is not possible to configure the standard sample of any concentration using any dilution ratio, and it is not possible to timely discover and judge the cause of abnormality or failure. For the fluctuation of the standard sample data, it is impossible to analyze and evaluate the quality control results and instrument performance. For the fluctuation of the water sample data, it is impossible to timely judge and verify the cause of the data fluctuation. For the long-term fluctuation of the water sample, there are problems such as the inability to realize remote dynamic quality control, the inflexible quality control method, and the quality control is also susceptible to human interference.

[0070] Furthermore, in order to solve the above-mentioned problem, the embodiment of the present application can obtain the target water sample concentration information of the target water sample in the process of using the water quality monitor to monitor the water quality of the target water sample; monitor whether the target water sample concentration information of the target water sample mutates; if a mutation occurs, determine whether the target water sample concentration information is greater than the first standard sample concentration information, the first standard sample concentration information is the concentration information corresponding to the first standard sample of the water quality monitor; determine the verification information according to the judgment result, the verification information includes: the identification information of the verification standard sample and the standard concentration information; control the water quality monitor, according to the identification information of the verification standard sample, perform concentration detection on the verification standard sample, and obtain the actual concentration information corresponding to the verification standard sample; verify according to the actual concentration information corresponding to the verification standard sample and the standard concentration information corresponding to the verification standard sample, and obtain the verification result; when the verification result is qualified, determine that the performance of the water quality monitor is normal, and output the retained water sample information, the retained water sample information is used to instruct the user to retain the target water sample; when the verification result is unqualified, determine that the performance of the water quality monitor is abnormal.

[0071] Furthermore, in the embodiments of the present application, an intelligent algorithm can be used to achieve any ratio within the allowable range and produce a quality control solution of any concentration, which can effectively solve the problem of having only a few fixed ratios.

[0072] Specifically, the present application provides a quality control method for a water quality monitoring instrument, such as Figure 1 As shown, the method provided in the embodiment of the present application can be executed by an electronic device, and the electronic device is a server or a terminal device. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a water quality monitor, etc., but is not limited thereto. The embodiment of the present application is not limited here, and the method includes:

[0073] S101, in the process of monitoring the water quality of the target water sample using the water quality monitor, obtaining target water sample concentration information of the target water sample;

[0074] The target water sample is the water sample being monitored, and each time the target water sample is tested, the concentration information is stored.

[0075] In a feasible implementation, in the process of using a water quality monitor to monitor the water quality of a target water sample, the target water sample concentration information is constantly monitored to see whether it meets the safe water sample concentration. If not, S102 is triggered to trigger an alarm mechanism to judge the data and conduct standard sample verification.

[0076] S102, monitoring whether target water sample concentration information of the target water sample has a sudden change;

[0077] In some embodiments, whether a mutation has occurred can be determined in a variety of ways:

[0078] Optionally, it is determined whether the difference between the historical water sample concentration information and the current concentration information exceeds a preset threshold. If so, it is determined that a mutation has occurred. The preset threshold can be set by the user according to actual needs. It should be understood that the historical water sample concentration information should be the concentration information when the water quality is normal.

[0079] Optionally, determine whether the concentration growth rate determined by the historical water sample concentration information and the current concentration information exceeds a preset growth rate threshold. If so, determine that a mutation has occurred. The preset growth rate threshold can be set by the user according to actual needs;

[0080] Optionally, determining whether the difference between the target water sample concentration information and the standard water sample concentration information is within a preset difference range, and if not, determining that a mutation occurs;

[0081] The historical water sample concentration information may be the last water sample concentration information, or may be the average of multiple historical water sample concentration information. Of course, it may also be in other forms, which is not limited in the embodiments of the present application.

[0082] It is understandable that other methods may be used to determine whether a mutation occurs, which are not limited here.

[0083] If no mutation occurs, it means the instrument may be normal. If a mutation occurs, it may be caused by abnormal instrument performance or a mutation in water quality.

[0084] S103, if a mutation occurs, determine whether the target water sample concentration information is greater than the first standard sample concentration information, where the first standard sample concentration information is the concentration information corresponding to the first standard sample of the water quality monitor;

[0085] The concentration information of the first standard sample is the concentration information when the water quality monitor is calibrated.

[0086] S104, determining verification information according to the judgment result, the verification information including: identification information of the verification standard sample and standard concentration information;

[0087] Among them, the identification information is used to prepare verification standard samples.

[0088] Specifically, when the judgment result is that the concentration of the target water sample after the mutation is not greater than the concentration of the first standard sample, the identification information of the fixed standard sample and the fixed standard sample concentration information are determined; at this time, the fixed concentration is used for verification again. If the verification passes, it means that the instrument performance is normal and the water quality has undergone a significant change, and it is not a mutation caused by abnormal instrument performance; if the verification fails, it means that there is a high probability that the mutation is caused by abnormal instrument performance.

[0089] When the result of the judgment is that the concentration of the target water sample after the mutation is greater than the concentration of the first standard sample, the identification information of the second standard sample and the concentration information of the second standard sample are determined, wherein the concentration information of the second standard sample is within the preset range of the concentration information of the target water sample. At this time, it may be due to the low concentration of the first standard sample that the data has changed significantly. The second standard sample can be used for re-verification to determine whether the mutation is caused by a significant change in water quality or an abnormal instrument performance.

[0090] The concentration information of the second standard sample is the concentration of the multiple standard samples that is closest to the concentration of the first standard sample. The multiple standard samples are water quality samples with corresponding standard concentration information corresponding to each of the preset multiple channels.

[0091] S105, controlling the water quality monitoring instrument to perform concentration detection on the verification standard sample according to the identification information of the verification standard sample, and obtaining actual concentration information corresponding to the verification standard sample; verifying according to the actual concentration information corresponding to the verification standard sample and the standard concentration information corresponding to the verification standard sample, and obtaining a verification result;

[0092] When the verification standard sample is a fixed standard sample, the water quality monitor is controlled to switch the channel to adjust the standard sample to the fixed standard sample according to the identification information of the verification standard sample, and the water quality monitor is used to detect the concentration of the fixed standard sample to obtain the actual concentration information corresponding to the fixed standard sample, and determine the difference between the actual concentration information corresponding to the fixed standard sample and the standard concentration information corresponding to the fixed standard sample. If the difference is within a first preset difference range, the verification result is determined to be qualified, otherwise it is unqualified, wherein the first preset difference range can be set according to actual needs.

[0093] When the verification standard sample is the second standard sample, the water quality monitor is controlled to switch the channel according to the identification information of the verification standard sample to adjust the standard sample to the second standard sample, and the water quality monitor is used to detect the concentration of the second standard sample to obtain the actual concentration information corresponding to the second standard sample, and determine the difference between the actual concentration information corresponding to the second standard sample and the standard concentration information corresponding to the second standard sample. If the difference is within the second preset difference range, the verification result is determined to be qualified, otherwise it is unqualified. Among them, the second preset difference range can be set according to actual needs, and the first preset difference range and the second preset difference range can be the same or different.

[0094] S106. When the verification result is qualified, it is determined that the performance of the water quality monitor is normal, and the retained water sample information is output, and the retained water sample information is used to instruct the user to retain the target water sample; when the verification result is unqualified, it is determined that the performance of the water quality monitor is abnormal.

[0095] Through the above technical scheme, during the process of the water quality monitor monitoring the water quality of the target water sample, if the concentration of the currently monitored water sample suddenly changes, the verification standard sample is determined according to the size relationship between the target water sample concentration information and the first standard sample concentration information, and the standard sample verification is carried out to automatically identify whether the mutation is caused by abnormal water sample or abnormal instrument performance. Quality control is also carried out during the actual detection process to facilitate timely discovery and correction of deviations in the detection, improve the accuracy of instrument quality assessment, and thereby ensure the accuracy and reliability of the test results.

[0096] Furthermore, when the verification result is unqualified, the water quality monitor can also be diagnosed to obtain the diagnosis result. Figure 2 , Figure 2 A schematic diagram of a water quality abnormality or exceeding standard verification process is provided for the embodiment of the present application. The water quality abnormality or exceeding standard verification process can be used to verify the performance of the instrument when abnormal data appears. When the data of the monitored water sample is better or worse than the set threshold, the alarm mechanism is immediately triggered to judge the data, and a standard sample verification is carried out. If the target water sample concentration information at this time is greater than the first standard sample concentration information, it means that the standard sample concentration is too low and does not meet the verification requirements. According to the trend of the water sample concentration change, the second standard sample with a standard sample concentration close to the sample concentration is dynamically configured and the test is completed, so as to automatically identify abnormal values ​​in the monitoring data and verify the reliability and applicability of the instrument; if it is not greater than the first standard sample concentration information, a fixed concentration standard sample is used for verification. Determine whether to enter the abnormal diagnosis process based on the verification results. After entering the diagnosis process, quickly locate the problem and output a diagnosis report. The diagnosis report at least contains the operating health status of each hardware of the instrument and effective treatment measures.

[0097] Furthermore, in order to more accurately determine the root cause of the water quality problem, in the embodiment of the present application, the trend comparison of related parameters is carried out, and the relationship between multiple water quality parameters is comprehensively considered to perform correlation analysis. When a parameter undergoes a trend change, the related parameters will also have the same or opposite trend change. If only a single parameter undergoes a trend change, it is very likely that the instrument has failed. Therefore, when the related parameters are abnormal, check the changes in other related parameters and supplement the quality control verification measures to more accurately determine the root cause of the water quality problem. Specifically, the target water sample concentration information includes the concentration information of multiple parameter types; after obtaining the target water sample concentration information of the target water sample, it also includes:

[0098] Determine, from multiple parameter types, associated parameter types and associated conditions of a target parameter type, the target parameter type being any one of the multiple parameter types, and the associated conditions including changes in the same trend and changes in the opposite trend;

[0099] Acquire concentration change information corresponding to each of the concentration information of multiple parameter types of the target water sample;

[0100] If the concentration change information corresponding to the target parameter type and the concentration change information corresponding to the associated parameter type meet the associated condition, then the concentration information of the target parameter type is determined to be valid information;

[0101] If the concentration change information corresponding to the target parameter type and the concentration change information corresponding to the associated parameter type do not conform to the associated situation, the concentration information obtained by the water quality monitoring instrument testing the third standard sample is obtained; and the concentration information corresponding to the third standard sample and the standard concentration information corresponding to the third standard sample are used to determine the validity of the concentration information of the target parameter type.

[0102] The electronic device pre-stores association information between multiple parameter types, and the association information includes: association objects and association conditions, which can be stored in the form of a directed graph or a table.

[0103] Exemplarily, parameter type a is selected from multiple parameter types, and the associated parameter type b and the associated situation (for example, the same trend) associated therewith are determined; if the concentration change information (increasing trend) corresponding to the target parameter type and the concentration change information (increasing trend) corresponding to the associated parameter type meet the associated situation, the next parameter type c is determined; if the concentration change information (increasing trend) corresponding to the target parameter type and the concentration change information (declining trend) corresponding to the associated parameter type do not meet the associated situation, the data may be invalid at this time, and the third standard sample is used for verification. If the verification is successful, it means that the data is valid, otherwise it is determined that the data is invalid.

[0104] It is understandable that a group of associated parameter types can be selected to verify the validity of the data; or all associated parameter types can be selected to verify the validity of the data, and only when all verifications are successful can the data be considered valid; this is not limited here.

[0105] like Figure 3 As shown, after determining the abnormal data change, the correlated parameters can be automatically compared. If the trend is logical, the concentration information of the target parameter type currently obtained is determined to be valid. Otherwise, it is necessary to use the standard sample to verify again. If the standard sample error comparison is qualified, the concentration information of the target parameter type is determined to be valid. If it is unqualified, the data is determined to be invalid.

[0106] Only when the data is valid is the step of monitoring whether the target water sample concentration information of the target water sample has a sudden change based on the historical water sample concentration information of the target water sample executed. If the data is invalid, a warning message is issued to prompt the user.

[0107] It can be seen that in the embodiment of the present application, the associated parameter types and associated situations associated with the target parameter category are identified and determined from multiple parameter categories, and these concentration change information are used to compare whether the change trend of the target parameter type and its associated parameter type conforms to the preset association situation, to preliminarily judge whether the concentration information of the target parameter type is valid information. If the preliminary judgment result does not conform to the association situation, a verification mechanism is used to more accurately judge whether the concentration information of the target parameter type is valid, thereby improving the accuracy and reliability of water quality monitoring and reducing the waste of resources and the risk of false alarms caused by misjudgment.

[0108] Furthermore, the solution provided in the embodiment of the present application can also be tested at a fixed period. In the related art, in the process of testing at a fixed period, the direct comparison result between the test paper and the standard value is simply relied on as a quality control method. However, due to other factors, the actual measured value may fluctuate, making the actual measured value inaccurate, which may cause the instrument evaluation result to be wrong. In the embodiment of the present application, a quality control request of the water quality monitor is obtained; according to the quality control request, the corresponding concentration information obtained by the water quality monitor for testing the first standard sample at multiple times is obtained; based on the concentration information corresponding to the first standard sample at multiple times, a trend analysis is performed to determine the concentration change information; it is determined whether the concentration change information is within the preset concentration change range; if the concentration change information is not within the preset concentration change range, the water quality monitor is calibrated, and the calibrated water quality monitor is verified; if the concentration change information is within the preset concentration change range, it is determined that the performance of the water quality monitor is normal. By analyzing whether the concentration change information of the concentration information corresponding to the first standard sample at multiple times is within the preset concentration change range, it is determined whether the performance of the water quality monitor is normal. If it is abnormal, the water quality monitor is calibrated and the calibrated water quality monitor is verified. For details, see Figure 4 , Figure 4 A flow chart of another quality control method of a water quality monitor provided in an embodiment of the present application, which is combined with the quality control in the process of water quality monitoring, can improve the accuracy of quality control, and the method includes:

[0109] S201, obtaining a quality control request of a water quality monitoring instrument;

[0110] Among them, the method of obtaining the quality control request of the water quality monitor may include any of the following: obtaining the quality control request issued by the quality control verification program; obtaining the quality control request issued by the calibration program; obtaining the quality control request sent by the remote verification platform, wherein the quality control request sent by the remote verification platform includes the parameter information for controlling the configuration of the first standard sample of the water quality monitor; the parameter information includes: the dilution multiple corresponding to the blind sample or the concentration corresponding to the standard sample.

[0111] The quality control verification procedure and calibration procedure are used to regularly calibrate and verify the accuracy of monitoring instruments. Users can set the verification cycle / calibration cycle according to management needs, automatically trigger the calibration procedure and quality control verification procedure, and use standard solutions to automatically calibrate and verify the monitoring instruments regularly.

[0112] For the quality control request sent by the remote verification platform, the concentration of the standard solution to be verified can be set through the control platform, and the preparation instructions can be sent to the substation software to control the quality control instrument to prepare the standard sample. After the water quality monitor extracts the standard sample for analysis, the data is transmitted to the platform to obtain the concentration information.

[0113] S202, according to the quality control request, obtaining the concentration information corresponding to each of the first standard sample tested by the water quality monitor at multiple times;

[0114] The first standard sample can be selected according to actual needs, and the water quality can be tested using a water quality monitor to obtain concentration information. The concentration information can include the concentration of a class of solutes or the concentration of a certain element, which is not limited in the present embodiment.

[0115] S203, performing trend analysis based on the concentration information corresponding to the first standard sample at multiple times to determine concentration change information;

[0116] In an embodiment of the present application, fitting can be performed based on multiple concentration information to obtain a trend line; through the trend line, at least one of the overall change trend (increasing, decreasing, or remaining stable, as well as the rate of increase, the rate of decrease), the mean, the range, the standard deviation, and the repeatability information can be obtained as the concentration change information.

[0117] S204, determining whether the concentration change information is within a preset concentration change range;

[0118] S205. If the concentration change information is not within the preset concentration change range, the water quality monitor is calibrated and the calibrated water quality monitor is verified; if the concentration change information is within the preset concentration change range, it is determined that the performance of the water quality monitor is normal.

[0119] Among them, the preset concentration change range is the preset change range, and the changes within this range are allowed changes, indicating that the water quality monitor is operating normally.

[0120] If the concentration change information is within the preset concentration change range, when it is determined that the instrument performance is normal, a quality control log is automatically generated and stored; if the concentration change information is not within the preset concentration change range, it is very likely that the instrument performance is abnormal. The parameters of the water quality monitor can be corrected, and the water quality monitor after the corrected parameters can be verified again to determine the abnormal performance.

[0121] In an embodiment of the present application, when performing re-verification, the first standard sample can be tested multiple times to obtain multiple concentration information, and then a trend analysis can be performed to determine whether the concentration change information is within a preset concentration change range; it can also be a single measurement method to obtain concentration information, and the concentration information is compared with the standard concentration information to determine the performance of the water quality monitor; of course, it is also possible to change the standard sample concentration for single / multiple tests to determine the performance of the water quality monitor.

[0122] The present application embodiment does not limit the calibration process, and the user can implement it according to relevant technologies.

[0123] It can be seen that in the embodiment of the present application, after receiving the quality control request, the corresponding concentration information of the water quality monitor obtained by testing the first standard sample at multiple times can be obtained, and trend analysis can be performed to determine the concentration change information, and judge whether this information is within the preset concentration change range. If the concentration change information exceeds the preset range, the system immediately starts the calibration procedure and verifies the calibrated water quality monitor to ensure that its performance returns to normal; if the concentration change information is within the preset range, the system confirms that the performance of the water quality monitor is normal, and no additional calibration and verification work is required, thereby realizing real-time monitoring and rapid response to the performance of the water quality monitor, and effectively ensuring the accuracy and reliability of the water quality monitoring data.

[0124] A possible implementation method of the present application embodiment is shown in Figure 5 Specifically, the monitoring instrument is automatically calibrated and automatically checked regularly using standard solutions. After calibration and checking, data is collected and processed, the trend changes of calibration and verification results are analyzed, and a trend change report is output. The calibration results and quality control data are dynamically checked and corrected based on statistical algorithms to evaluate instrument performance, and an instrument performance report is output. The report contains at least quality control charts such as mean-range and mean-standard deviation, as well as comprehensive performance indicators such as repeatability and accuracy. Dynamic verification of quality control data is performed to determine the relationship between concentration change information and the preset concentration change range. If the concentration change information is not within the preset concentration change range, the calibration parameters are automatically adjusted and the parameters are verified; in addition, the instrument performance can also be evaluated, a performance report is output, and maintenance recommendations are provided. Specifically, the method also includes: obtaining the operating parameters corresponding to each of the multiple parts of the water quality monitor; for each part, determining whether the operating parameters corresponding to the part meet the preset normal operating threshold range; if there is a non-compliance, the water quality monitor is determined to be abnormal, and maintenance recommendations are generated based on the abnormal components.

[0125] In the embodiment of the present application, a comprehensive judgment is made by combining the real-time changes of the operating parameters corresponding to each of the multiple parts (such as ORP potential, blank light intensity, reaction temperature, metering signal, etc.). By setting the threshold range of each operating parameter, when a certain operating parameter does not meet the preset conditions, it is determined that the monitoring data is abnormal and the instrument may be abnormal. This method can also improve the accuracy and reliability of the determined data, but this method has the disadvantages of poor consistency between instruments and being greatly affected by the environment.

[0126] The means provided in the embodiments of the present application may be performed after S205 or after S202 to generate maintenance recommendations and verify the validity of data obtained through the water quality monitor test, or in other embodiments to verify the validity of data obtained through the water quality monitor test. The data can only be used after the validity verification is passed. In either case, the embodiments of the present application are no longer limited.

[0127] Of course, it is also possible to make abnormal judgments by setting the weights and threshold ranges of each operating parameter. For example, after determining whether each operating parameter is within the corresponding threshold range, determine a value for each part based on the result, such as no longer setting it to 0 instead of 1. Then each part has a corresponding weight value, and a weighted calculation is performed based on the weight value and the determined value to obtain a comprehensive value. When the comprehensive value exceeds the preset comprehensive threshold, it is determined that the current data is abnormal, and self-inspection is required to determine the abnormal components and obtain maintenance recommendations corresponding to the abnormal components.

[0128] It can be seen that in the embodiment of the present application, a comprehensive judgment is made based on the real-time changes of the operating parameters corresponding to each of the multiple parts; by setting the threshold range, when a certain parameter does not meet the preset conditions, the instrument may be abnormal, and maintenance recommendations are generated based on the abnormal components to ensure the normal operation of the instrument and the accuracy of the data.

[0129] A possible implementation of the embodiment of the present application is to obtain a quality control request of a water quality monitoring instrument, including any of the following:

[0130] Obtain quality control requests issued by the quality control verification program;

[0131] Get the quality control request issued by the calibration program;

[0132] A quality control request sent by a remote verification platform is obtained, wherein the quality control request sent by the remote verification platform includes parameter information for controlling the configuration of a first standard sample in a water quality monitoring instrument; the parameter information includes: a dilution multiple corresponding to a blind sample or a concentration corresponding to a standard sample.

[0133] Further elaboration on the quality control request sent by the remote verification platform, such as Figure 6As shown, remote verification, the concentration of the standard solution (i.e., the first standard sample) to be verified is set through the control platform, and the preparation instruction is sent to the substation software deployed on the electronic device;

[0134] The standard sample can be configured manually or automatically;

[0135] When the automatic configuration method is adopted, the electronic device controls the water quality monitor to configure the first standard sample according to the quality control request and the parameter information of the first standard sample; controls the water quality monitor to perform concentration detection on the first standard sample, and obtains the corresponding concentration information obtained by the water quality monitor when testing the first standard sample at multiple times.

[0136] When the quality control instrument is used to prepare standard samples and the instrument extracts standard samples for analysis, the concentration information is transmitted to the platform (which can be a remote verification platform or a substation software) to achieve the purpose of remote assessment of the analytical instrument and reduce human intervention.

[0137] It can be seen that in the embodiments of the present application, quality control requests can be issued through the quality control verification program, or the calibration program can issue quality control requests, or the standard sample concentration can be set through the platform and the standard sample verification can be remotely issued, effectively preventing human intervention in quality control verification.

[0138] In summary, the present application provides a more robust and comprehensive solution for improving the quality control method of water quality monitoring. Traditional quality control verification is to conduct standard sample testing by configuring standard samples of different concentrations and compare the test values ​​with the standard values. Although it is simple and direct, it is only through comparison that it is found that there is a certain deviation between the test value and the standard value, and it is impossible to locate the cause of the deviation. In addition, when the data fluctuates significantly, it is necessary to manually identify the anomaly and manually conduct standard sample testing and other quality control measures to further verify the instrument data. The core of the embodiment of the present application is to introduce a method of "automatically identifying abnormal data and automatically conducting standard sample testing, and the standard sample test results can be trend analyzed to evaluate instrument performance". This method has the following significant advantages:

[0139] (1) Improve data efficiency: By analyzing quality control trends, the instrument performance can be dynamically verified and corrected. At the same time, parameters can be automatically adjusted or instrument maintenance prompts can be provided according to performance conditions, forming preventive maintenance, reducing the probability of instrument failure, and effectively improving data efficiency;

[0140] (2) Improve the timeliness of abnormal response: When the monitoring data exceeds the set threshold, the alarm mechanism is immediately triggered to judge the data and conduct standard sample verification, so as to automatically identify abnormal values ​​in the monitoring data. Abnormal data caused by instrument abnormalities will enter the diagnosis process, quickly locate the problem and output a diagnosis report. The diagnosis report at least contains the operating health status of each hardware of the instrument and effective treatment measures, which improves the timeliness of abnormal data response;

[0141] (3) Reduce human intervention: Set the standard sample concentration through the platform and send the standard sample for verification remotely, effectively preventing human intervention in quality control verification;

[0142] (4) Improve the ability to identify abnormal data: By comparing the trends of related parameters, abnormal data can be indirectly discovered and effective quality control verification can be automatically taken to identify abnormal data in a timely manner.

[0143] In summary, the application of the quality control method of the embodiment of the present application has significant advantages and potential. By dynamically configuring standard samples for instrument analysis to verify instrument performance, the validity of data is verified through data collection, processing and analysis, the performance of the instrument is verified, instrument performance reports are output and parameters are automatically adjusted, which enriches the verification method of data validity, not only improves the accuracy, reliability and timeliness of abnormal data response of monitoring results, but also reduces maintenance costs and difficulties, and provides strong support for technological progress in the field of water quality monitoring.
