[0023] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0024] A method and system for calculating water level of a hydropower station based on credibility of multiple signal sources according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0025] Figure 1 is a flowchart of a method for calculating water level of a hydropower station based on credibility of multiple signal sources according to an embodiment of the present application. As shown in Figure 1 , the method can include but is not limited to the following steps:

[0026] Step S101: Obtain a fluctuation value and a current water level value corresponding to each measuring point in multiple measuring points.

[0027] For example, obtain the water level measurement value measured by the water level measuring device of each measuring point as the current water level value, and the water level fluctuation value corresponding to each measuring point.

[0028] In some embodiments, the current water level value of each measuring point can be obtained by converting the water level signal into a 4-20mA current signal according to the corresponding relationship between the water level and the 4-20mA current signal, and transmitting the signal to the collector through a cable.

[0029] In an alternative implementation, obtaining a fluctuation value corresponding to each measuring point in multiple measuring points includes: obtaining a historical water level value of each measuring point at a preset historical time; and obtaining a difference value between the historical water level value and the current water level value of each measuring point as the fluctuation value.

[0030] For example, if the current water level value of the Mth measuring point is h(t), the historical water level value of the measuring point before N sampling time is obtained, and the difference value between the historical water level value and the current water level value is obtained as the fluctuation value corresponding to the measuring point.

[0031] Step S102: Based on the fluctuation value corresponding to each measuring point, the corresponding current water level value is screened to obtain multiple candidate water level values.

[0032] For example, the current water level value of the measuring point with a water level fluctuation value less than or equal to a preset threshold value is taken as a candidate water level value.

[0033] Step S103: Based on the deviation between different candidate water level values in the multiple candidate water level values, at least one effective water level value is selected from the multiple candidate water level values.

[0034] For example, the mean value between each candidate water level value and the deviation value of other candidate water quality values is obtained, and the candidate water level value with the mean value less than or equal to a preset threshold value is taken as an effective water level value.

[0035] Step S104: Perform validity determination based on the first number of effective water level values and the number of measuring points of multiple measuring points.

[0036] Exemplarily, the water level value validity rate is calculated based on the first quantity of valid water level values and the quantity of measuring points in the plurality of measuring points, and if the validity rate is greater than or equal to a preset validity rate threshold, it is determined that the validity determination is passed.

[0037] Step S105: In response to passing the validity determination, an integrated water level value is obtained based on the valid water level values.

[0038] Exemplarily, a mean value of the valid water level values is obtained as the integrated water level value.

[0039] By implementing the embodiments of the present application, the measured water level values can be filtered multiple times according to the volatility of the measured water level values and the difference between the water level values of different measuring points, and an integrated water level value is obtained based on the filtered valid water level values. The credibility of the obtained integrated water level value can be improved.

[0040] In some embodiments, a water level fluctuation value corresponding to each measuring point can be obtained according to the water level change of each measuring point within a preset time period. As an example, please refer to Figure 2 , Figure 2 is another flowchart of a multi-signal-source hydropower station water level calculation method based on credibility provided by an embodiment of the present application. As shown in Figure 2 , the method can include but is not limited to the following steps:

[0041] Step S201: Obtain a fluctuation value and a current water level value corresponding to each measuring point in a plurality of measuring points.

[0042] In an embodiment of the present application, step S201 can be implemented by any of the embodiments of the present application, and the present application does not limit this and will not be repeated.

[0043] Step S202: Filter the current water level value corresponding to each measuring point based on the fluctuation value corresponding to the measuring point, and obtain a plurality of candidate water level values.

[0044] In an embodiment of the present application, step S202 can be implemented by any of the embodiments of the present application, and the present application does not limit this and will not be repeated.

[0045] Step S203: Obtain a plurality of difference values between each candidate water level value and other candidate water level values in the plurality of candidate water level values.

[0046] Exemplarily, taking M candidate water level values as an example, the difference value between a first candidate water level value and each second candidate water level value in the M candidate water level values is obtained. Wherein, the first candidate water level value is any one of the M candidate water level values, and the second candidate water level value is any one of the M candidate water level values except the first candidate water level value.

[0047] Step S204: Obtain a first number of target difference values that are less than or equal to a preset threshold value, from a plurality of difference values corresponding to each candidate water level value.

[0048] For example, taking M candidate water level values, the number of target difference values that are less than or equal to a preset threshold value (for example, 0.5 meters) are obtained from M-1 difference values corresponding to a first candidate water level value in the M candidate water level values, and the number of target difference values is determined.

[0049] Step S205: Obtain a confidence level corresponding to each candidate water level value based on a total number of difference values corresponding to each candidate water level value and the number of difference values.

[0050] For example, taking M candidate water level values, and the second number corresponding to the first candidate water level value is N, then the total number of difference values corresponding to each candidate water level value is M-1, and the confidence level corresponding to the first candidate water level value can be represented as N / M.

[0051] Step S206: Obtain a candidate water level value with a confidence level greater than or equal to a confidence threshold value as an effective water level value.

[0052] For example, if the confidence level corresponding to the first candidate water level value is greater than the preset confidence threshold value, the first candidate water level value is taken as an effective water level value.

[0053] Step S207: Perform effectiveness determination based on the first number of effective water level values and the number of measurement points of the plurality of measurement points.

[0054] In the embodiments of the present application, step S207 can be implemented by any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0055] Step S208: In response to the effectiveness determination, obtain a comprehensive water level value based on the effective water level value.

[0056] In the embodiments of the present application, step S208 can be implemented by any one of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0057] By implementing the embodiments of the present application, the effective water level value can be obtained based on the deviation between each candidate water level value and other candidate water level values, and the comprehensive water level value can be obtained based on the effective water level value. The candidate water level value with poor reliability can be eliminated to improve the accuracy of the obtained comprehensive water level value.

[0058] In some embodiments, the number of effective water level values can be determined to determine whether the currently measured comprehensive water level value is effective. As an example, please refer to Figure 3 , Figure 3is a flowchart of another method for calculating water level of a hydropower station based on credibility of multiple signal sources provided by the embodiments of the present application. As shown in Figure 3 the method can include but is not limited to the following steps:

[0059] Step S301: Obtain a fluctuation value and a current water level value corresponding to each of a plurality of measuring points.

[0060] In the embodiments of the present application, step S301 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0061] Step S302: Based on the fluctuation value corresponding to each of the measuring points, the corresponding current water level value is screened to obtain a plurality of candidate water level values.

[0062] In the embodiments of the present application, step S302 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0063] Step S303: Based on the deviation between different candidate water level values in the plurality of candidate water level values, at least one effective water level value is screened from the plurality of candidate water level values.

[0064] In the embodiments of the present application, step S303 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0065] Step S304: Obtain a ratio of a second number of effective water level values to a number of measuring points.

[0066] Step S305: In response to the ratio being greater than a preset threshold, determine that the effectiveness is determined.

[0067] Step S306: Obtain a comprehensive water level value based on the effective water level value.

[0068] In the embodiments of the present application, step S306 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated.

[0069] By implementing the embodiments of the present application, whether the current measurement is effective can be determined based on the ratio between the number of effective water level values and the number of measuring points, and the average value of the effective water level values is obtained as the comprehensive water level value when it is determined that the current measurement is effective. The credibility of the measured water level value can be improved.

[0070] In some embodiments, the above-mentioned measuring points can include reservoir water level measuring points and / or tail water level measuring points, the corresponding comprehensive reservoir water level can be obtained according to the current reservoir water level corresponding to the reservoir water level measuring points, and the corresponding comprehensive tail water level can be obtained according to the current reservoir water level corresponding to the tail water level measuring points, so as to obtain the difference between the comprehensive reservoir water level and the comprehensive tail water level as the water head of the hydropower station.
