[0026] like Figure 1 As shown, it is a flow chart of a method for analyzing the tendency error of a seawater temperature, salinity and depth meter provided by the first aspect of the present invention, and the method comprises the following steps:
[0027] S10, collecting temperature, salinity and depth data measured by multiple temperature, salinity and depth instruments of the same batch at different locations and time points in the sea area to be measured;
[0028] S20, obtaining seawater flow data of the sea area to be measured and establishing a seawater flow model;
[0029] S30, merging the data collected by each temperature-salinity-depth instrument into the seawater flow model, and using the Bayesian algorithm to find the flying point data, which is the data that does not conform to the statistical law;
[0030] S40, arranging the flying point data of each temperature-salinity-depth instrument into a flying point matrix;
[0031] S50, based on the historical data collected by the temperature-salinity-depth instrument with a single-cause error, and using the method of steps S10 to S40, construct a flying point matrix with different single-cause errors, recorded as an error flying point matrix set;
[0032] S60, matching the flying point matrix with the flying point matrix set, and taking the single cause error corresponding to the optimal matching result as the tendency error corresponding to the flying point matrix.
[0033] The specific implementation methods of the above steps are described in detail below:
[0034] The specific implementation process of collecting the same batch of data from multiple temperature, salinity and depth instruments in the sea area to be measured in step S10 is as follows:
[0035] (1) Determine the scope of the sea area to be measured. This method is applicable to offshore and open sea environments, and the sea area range is 10-100 kilometers. It can be described using latitude and longitude coordinates or projection coordinates.
[0036] (2) The data of the temperature-salinity-depth instrument are those of the temperature-salinity-depth instruments deployed in the same batch;
[0037] (3) Deploy multiple temperature, salinity and depth meters in the sea area to be measured. The instrument location distance is representative and can collect environmental information at different locations. Generally, they are placed at three heights: surface, middle and bottom layers, with 2-3 instruments deployed at each depth.
[0038] (4) Adjust the sampling time interval and duration of the temperature, salinity and depth instrument. Considering the response time of water body changes, the interval is set to 1-10 minutes; the duration covers representative environmental change processes, such as tidal cycles.
[0039] (5) Retrieve the deep sampler and download real-time or offline data. Check the data format and storage to ensure integrity.
[0040] (6) Data quality control. Delete obviously erroneous data. Check time stamps and delete time jump data.
[0041] The specific implementation method of obtaining flow data and establishing a model in step S20 is as follows:
[0042] (1) Determine that the sea area scale for collecting model-related data is 10-100 kilometers, which is consistent with the sea area scale in step S10.
[0043] (2) Collect flow-related data, including wind fields, waves, tides, ocean currents, etc. The data source can be satellite remote sensing, automatic stations, and numerical model products.
[0044] (3) Establish a hydrodynamic coupling model for the marine environment. The VOF method, particle method, smooth particle method, etc. can be used to simulate flow fields and turbulence.
[0045] (4) Set the model boundary conditions, including wind stress, pressure field, etc., to drive the model movement.
[0046] (5) In addition to hydrodynamics, additional parameter models such as temperature and salinity can be coupled.
[0047] (6) Perform numerical calculations and output flow field results. Check quality, such as mass conservation, etc.
[0048] (7) Verify observation data. Extract site data and compare them with model results. Determine the model error range.
[0049] Step S30 is used to project the temperature-salinity-depth instrument data onto the flow model to realize anomaly recognition. Specifically, the data collected by each temperature-salinity-depth instrument is merged into the seawater flow model, and the Bayesian algorithm is used to find the flying point data, which is the data that does not conform to the statistical law, including the following specific steps:
[0050] (1) Set mapping parameters. Determine the time and space mapping relationship, taking into account the model error, generally taking 1.2 times the model error range.
[0051] (2) Data location tag: Add location coordinates and time tags to each temperature, salinity and depth instrument data.
[0052] (3) Based on the mapping relationship, the labeled data is mapped into the flow model field.
[0053] (4) Compare the data with the flow field results. Extract statistical parameters such as mean value, standard deviation, etc.
[0054] (5) Using Bayesian theory, a data anomaly probability test model is established. Assuming that the temperature-salinity-depth instrument data conform to the prior distribution of the flow field, the posterior probability is calculated.
[0055] (6) Set a threshold to determine whether the abnormal probability exceeds the threshold. Divide into abnormal flying points and normal points.
[0056] (7) Calculate the distribution of flying points and the proportion of total points at each measuring station to reflect the severity of the error.
[0057] The specific implementation method of arranging the flying point matrix in step S40 is as follows:
[0058] (1) Set the row and column components of the matrix. The rows of the matrix correspond to each temperature, salinity and depth instrument, and the columns represent various types of anomalies, such as sensor drift, residual thermal error, instrument reset, etc.
[0059] (2) Determine the data time span. It can be more than one year.
[0060] (3) Count the number of flying points of each temperature, salinity and depth instrument and classify them into the corresponding error type. Calculate the flying point ratio according to the thermal measurement counting method.
[0061] (4) Generate a thermal map matrix. The value of the matrix reflects the amount of error corresponding to the instrument, and the error characteristics can be judged intuitively.
[0062] (5) Repeat (1) to (4) to obtain heat maps at different time spans and observe the changing trend. You can also generate a dynamic map to display the results.
[0063] The method for simulating the error flying point matrix set based on historical data in step S50 is as follows:
[0064] (I) Obtain the historical observation data set of the temperature-salinity-depth instrument with a single error.
[0065] 1. Query the historical calibration data set from the measuring station and find the data of parameter drift.
[0066] 2. Retrieve the original data of the long-term deployed temperature, salinity and depth meters, and manually screen out the devices with single errors.
[0067] (ii) Process these historical data using steps S10 to S40 to obtain a flying point matrix corresponding to a single error. The matrix result is stored in the sample library.
[0068] (III) For various single errors, repeatedly obtain multiple sets of matrix samples and construct error matrix sets. The more matrix sets there are, the more accurate the error discrimination results will be.
[0069] (IV) Optimize the sample set content. Consider the representativeness and uniformity of samples based on different equipment types, years of service, initial accuracy, etc.
[0070] The implementation process of discriminating error categories based on matrix matching in step S60 is as follows:
[0071] (1) Establish an error discrimination model. Import the trained error matrix sample set, extract features for supervised learning, and obtain the discriminant function.
[0072] (2) Process the data of the temperature, salinity and depth meter to be measured into a flying point matrix format.
[0073] (3) Input the matrix into the discriminant model. The model calculates the projection response value of the matrix on each error category.
[0074] (4) The algorithm identifies the single error type with the largest response and outputs the identification result.
[0075] (5) Repeat the test multiple times and statistically analyze the results. Calculate the accuracy of all samples and evaluate the stability of the model.
[0076] (6) Connect to the database, feed back and store new samples and discrimination results, expand the sample library, and optimize the model online.
