DETAILED DESCRIPTION

[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0049] First, the terms involved in this application are explained:

[0050] Reference electrode: refers to an electrode commonly used in electrochemical measurements, whose potential is known and remains constant. In soil potential testing, the reference electrode can be used to measure the potential difference between buried structures (such as oil pipelines, chemical containers, etc.) and the soil to monitor corrosion. For example, a silver / silver-chloride electrode can be used as a reference electrode, whose potential is known and relatively stable.

[0051] Test piece: refers to the sample used for electrochemical testing, which can be a metal piece. For example, in soil potential testing, the test piece can be used to contact different types of reference electrodes to test the effect of different reference electrodes on potential measurement.

[0052] Natural potential: refers to the potential difference between the reference electrode and the test piece when there is no current flowing at both ends of the measurement system. In soil potential testing, it represents the electrochemical equilibrium state between soil and metal.

[0053] The first potential extreme value and the second potential extreme value refer to the highest and lowest values ​​of the potential within a period of time in electrochemical measurements as time, temperature, humidity and other factors change. The difference between the first potential extreme value and the second potential extreme value can also be called the potential fluctuation range.

[0054] Target reference electrode: refers to a reference electrode that can stably output potential and whose fluctuation range is within an acceptable range when measuring soil potential.

[0055] Soil data: refers to a list of physical and chemical properties of soil, which may include soil pH, soil texture (such as sand, loam, clay), soil moisture content, organic matter content, electrolyte concentration in the soil (such as chloride ion content), soil temperature, and soil moisture, etc. Soil data helps to evaluate the impact of soil on metal corrosion and can provide a basis for selecting a suitable reference electrode.

[0056] In the existing technology, researchers mainly use copper sulfate reference electrodes to provide a stable and known potential reference to test the pipe-to-ground potential of buried soil structures. However, the soil types in which buried structures are located are diverse, and selecting reference electrodes suitable for the soil types in which buried structures are located faces many challenges, and is time-consuming and costly.

[0057] The present application provides a reference electrode determination method, device, equipment and medium, which are applied to an electrode testing device. The electrode testing device includes a reference electrode and a test piece corresponding to the reference electrode. The test piece is tested by using different types of reference electrodes to obtain the natural potential of different types of reference electrodes in the same soil environment and the potential fluctuation range of their natural potential. The target reference electrode that meets the potential fluctuation range requirements among different types of reference electrodes is determined by the natural potential, potential fluctuation range and potential fluctuation range requirements of different types of reference electrodes, so as to screen out reference electrodes with higher stability under different environmental conditions, thereby meeting the testing requirements for reference electrodes under different environmental conditions.

[0058] Figure 1 This is a schematic diagram of the structure of the electrode testing device provided in this application. Figure 1 As shown, the electrode test determination device includes a first reference electrode 110, a second reference electrode 111, a third reference electrode 112, a first test strip 210, a second test strip 211, a third test strip 212, a multi-channel recorder 310 and a soil detector 410, wherein:

[0059] The first reference electrode 110 is electrically connected to the first test strip 210, the second reference electrode 111 is electrically connected to the second test strip 211, and the third reference electrode 112 is electrically connected to the third test strip 212. The natural potential of the test strips connected to the first reference electrode 110, the second reference electrode 111 and the third reference electrode 112 can be measured.

[0060] The first test strip 210, the second test strip 211 and the third test strip 212 are electrically connected to the multi-channel recorder 310, which is used to regularly measure and record the natural potential of the corresponding test strips, and reflect the stability of the reference electrode by analyzing the change trend of the natural potential. When the potential of the reference electrode is stable, the measured natural potential should be maintained within a relatively constant range. For example, if the natural potential of the same test strip is measured at the same time point every day, the obtained data points can be closely clustered around an average value, and the fluctuation range is only within a few millivolts (mV) relative to the average value. When the reference electrode is unstable, it may cause significant changes in the natural potential measured at different times or under different environmental conditions. For example, if the natural potential measurement value within a day gradually increases by tens of millivolts or even more from morning to evening, or the potential difference of each measurement reaches tens of millivolts, this indicates that there is a significant change, which indicates that the reference electrode may have a stability problem.

[0061] The electrode test determination device may further include a fourth reference electrode, a fifth reference electrode, a sixth reference electrode, and a seventh reference electrode, and the reference electrode types of the fourth reference electrode, the fifth reference electrode, the sixth reference electrode, and the seventh reference electrode may be different from each other, and are all different from the reference electrode types of the first reference electrode 110, the second reference electrode 111, and the third reference electrode 112. Thus, the target reference electrode can be better determined.

[0062] The soil detector 410 is set in the soil and can collect various soil parameters through sensors, including soil temperature, humidity, pH value and moisture content.

[0063] Figure 2 A schematic diagram of a reference electrode determination method provided in this application. Figure 2 As shown, the reference electrode determination method is applied to an electrode testing device, and the method comprises:

[0064] S201, determining test potential results of testing a test piece using different reference electrodes, wherein different reference electrodes have different types of reference electrodes.

[0065] Among them, the test potential results of testing the test strip with different reference electrodes can be obtained through a multi-channel recorder under consistent environmental conditions (such as soil temperature, humidity, pH value, etc.), and the test potential results between the test strip and the reference electrode can be displayed on the multi-channel recorder. The test potential results can include the natural potentials of different reference electrodes, that is, the potential difference between different reference electrodes and the test strip.

[0066] Different types of reference electrodes may include copper sulfate reference electrode, gel reference electrode, high purity zinc reference electrode, graphite rod reference electrode, silver / silver chloride reference electrode, manganese dioxide reference electrode, etc. By connecting copper sulfate reference electrode, gel reference electrode, high purity zinc reference electrode, graphite rod reference electrode, silver / silver chloride reference electrode or manganese dioxide reference electrode to the test strip and a multi-channel recorder, the test potential results of different reference electrodes tested on the test strip under the same environmental conditions can be obtained, and then the stability of different reference electrodes under the same environmental conditions can be analyzed.

[0067] In the embodiment of the present application, determining the test potential results of testing the test piece with different reference electrodes includes:

[0068] Determine the test time for the reference electrode to test the test piece;

[0069] According to the test time of the reference electrode on the test piece, the test potential results of the different reference electrodes on the test piece are determined.

[0070] Among them, each channel in the multi-channel recorder is connected to a different reference electrode. The measurement parameters of each channel, such as test time, data storage interval, etc., can be selected on the display interface of the multi-channel recorder. Then, according to the test time of the reference electrode on the test piece, the test potential results of the test piece tested by different reference electrodes are determined, and the test potential results are displayed in real time on the screen to help researchers monitor the progress of the experiment at any time. For example, the test time of the reference electrode on the test piece can be set to one month, and the test potential results of the test piece tested by different reference electrodes can be recorded every 10 minutes on the multi-channel recorder, thereby forming a natural potential fluctuation diagram of the reference electrode on the test piece within one month.

[0071] The test time for the reference electrode to test the test piece can be determined according to the characteristics of the reference electrode and the environmental conditions, wherein different reference electrode materials may show different stable potentials in the same time; soil type, soil pH, chloride ion content temperature, humidity, etc. may affect the stability of the reference electrode; in the embodiment of the present application, the test time can be determined based on the type of reference electrode and environmental conditions. For example, when a reference electrode of silver / silver chloride type is used for testing, the test time can be the time to identify any non-random potential drift, and the test time can be one week. When a reference electrode of copper sulfate type is used for testing, the test time can be one month, and when the soil pH and humidity change greatly, the test time can be several months, thereby accurately capturing the changing trend and fluctuation range of the potential of different reference electrodes.

[0072] S202. Determine the natural potential of the reference electrode and the potential fluctuation range of the natural potential according to the test potential result.

[0073] The test potential results include the natural potentials detected at different times. According to the data distribution of the natural potential of the reference electrode, the potential fluctuation range of the natural potential can be determined.

[0074] In the embodiment of the present application, the natural potential of the reference electrode and the potential fluctuation range of the natural potential are determined according to the test potential result, including:

[0075] Determine the natural potential of the reference electrode and the first potential extreme value and the second potential extreme value in the natural potential according to the test potential result;

[0076] The potential fluctuation range of the natural potential is determined according to the first potential extreme value and the second potential extreme value.

[0077] Among them, the collected potential data can be first processed, and the data processing can include removing outliers, checking whether there are obvious outliers in the data (such as potential jumps caused by instantaneous interference), and removing these outliers; smoothing processing, if the data contains noise of signal fluctuations that significantly deviate from the expected or normal range (due to external interference or instability within the measurement system), a smoothing method (such as moving average) can be used to reduce the impact of noise on the results, thereby obtaining the natural potential of the reference electrode.

[0078] For example, if a large electrical device is started or shut down nearby during potential recording, electromagnetic interference may be generated, causing a brief but drastic potential change. This change is usually unrelated to the actual electrochemical process, but is a one-time, transient abnormal value, that is, a sudden increase or decrease of 50mV in a stable potential recording, followed by a rapid return to the original level, which may be the noise result of transient interference.

[0079] After obtaining the natural potential of the reference electrode, the maximum and minimum values ​​in the natural potential are taken as the first and second potential extremes in the natural potential, and the absolute value of the difference between the maximum and minimum values ​​is taken as the potential fluctuation range of the natural potential of the reference electrode.

[0080] S203. Determine a target reference electrode that meets the potential fluctuation range requirement among the reference electrodes according to the potential fluctuation range of the natural potential.

[0081] Among them, the potential fluctuation range requirement can refer to the requirement for the minimum potential fluctuation range, or it can be a requirement that is less than the preset range threshold. Among them, when the potential fluctuation range requirement is the requirement for the minimum potential fluctuation range, different types of reference electrodes can be sorted according to the potential fluctuation range of the natural potential, so as to determine the minimum target reference electrode. For example, three different types of reference electrodes A, B, and C were continuously monitored for one month under the same experimental conditions (such as the same soil environment, temperature, humidity, etc.). At the end of each month, the natural potential fluctuation range of each reference electrode is calculated, that is, the difference between the highest potential and the lowest potential in a month, among which, reference electrode A: potential fluctuation range is 5 mV; reference electrode B: potential fluctuation range is 10 mV; reference electrode C: potential fluctuation range is 3 mV; thus, it can be determined that the minimum requirement for the potential fluctuation range is 3 mV, and the target reference electrode is reference electrode C.

[0082] When the potential fluctuation range requirement is less than the preset range threshold, the potential fluctuation range of the natural potential of different types of reference electrodes can be compared with the preset range threshold respectively to determine the target reference electrode. For example, four different types of reference electrodes A, B, C, and D were continuously monitored for three months under the same experimental conditions (such as the same soil environment, temperature, humidity, etc.). According to the application requirements, the threshold represented by the preset range threshold is 8 mV. When the potential fluctuation range of reference electrode A is 5 mV; the potential fluctuation range of reference electrode B is 10 mV; the potential fluctuation range of reference electrode C is 3 mV; and the potential fluctuation range of reference electrode D is 7 mV; it can be determined that the minimum requirement for the potential fluctuation range is 3 mV, and the target reference electrodes can be reference electrode A, reference electrode C, and reference electrode D, among which reference electrode C is the target reference electrode with the best effect.

[0083] In the embodiment of the present application, according to the potential fluctuation range of the natural potential, determining a target reference electrode that meets the potential fluctuation range requirement among the reference electrodes includes:

[0084] Obtaining potential comparison results of testing the test piece with different reference electrodes, wherein the test soil type of the potential comparison results is different from the test soil type of the test potential results;

[0085] According to the potential comparison result, determining the comparison natural potential of the reference electrode and the potential fluctuation range of the comparison natural potential;

[0086] According to the potential fluctuation range of the reference natural potential and the potential fluctuation range of the natural potential, a target reference electrode that meets the potential fluctuation range requirement among the reference electrodes is determined.

[0087] The potential control result may refer to the control natural potential obtained by testing the test piece using different types of reference electrodes under a soil type different from the test soil type, and the potential fluctuation range of the control natural potential.

[0088] During the control experiment, the number and type of reference electrodes selected by the control group are the same as those used in the test soil; the type of test piece selected by the control group (such as material, thickness, etc.) is the same as that used in the test soil; the temperature, humidity, soil moisture content, etc. of the soil are the same when the control group conducts the experiment; the soil type selected for the control group is significantly different from the test soil type, for example, if the test is conducted in acidic soil, neutral or alkaline soil can be selected for control.

[0089] By testing in soil types different from the test soil type, the performance of the reference electrode under different environmental conditions can be verified. The control group test provides the control natural potential and control potential fluctuation range of the reference electrode in different soil types, which can provide a more comprehensive understanding of which reference electrodes can maintain a stable potential fluctuation range under different conditions, and screen out target reference electrodes that can meet the potential fluctuation range requirements in different soil types.

[0090] In the embodiment of the present application, according to the potential fluctuation range of the natural potential and the potential fluctuation range of the reference natural potential, determining the target reference electrode that meets the potential fluctuation range requirement in the reference electrode includes:

[0091] Determining, according to the potential fluctuation range of the natural potential, a first target reference electrode that meets the first potential fluctuation range requirement among the reference electrodes;

[0092] Determining a second target reference electrode that meets the second potential fluctuation range requirement among the reference electrodes according to the potential fluctuation range of the reference natural potential;

[0093] A target reference electrode is determined based on the first target reference electrode and the second target reference electrode.

[0094] Among them, the first potential fluctuation range requirement and the second potential fluctuation range requirement may refer to the minimum potential fluctuation range requirement, or may be a requirement that is less than a preset range threshold. The potential fluctuation ranges of the natural potentials may be sorted in order from small to large, and a weight value may be assigned to the reference electrode whose potential fluctuation range of the natural potential ranks first, and then the difference between the potential fluctuation ranges of the first and second natural potentials is calculated, and then the weight value of the second reference electrode is determined according to the difference and the weight value of the first reference electrode, until the weight values ​​of all reference electrodes are obtained, and finally the reference electrode within the preset weight value range is used as the first target reference electrode. Similarly, the second target reference electrode in the control group may be obtained according to the potential fluctuation range of the control natural potential of each reference electrode in the control group.

[0095] The weight value of the first target reference electrode in the test soil and the weight value of the second target reference electrode in the control group can be added, and the reference electrode with the largest weight or greater than the preset range threshold after the addition is used as the target reference electrode.

[0096] Table 1 is a graph of the natural potential data of saline-alkali soil and control group soil provided by this application. As shown in Table 1:

[0097]

[0098] The saline-alkali soil was used as the test soil, and the test pieces were tested in the saline-alkali soil and the control group soil using copper sulfate reference electrode, gel reference electrode, high-purity zinc reference electrode, graphite rod reference electrode, silver / silver chloride reference electrode and manganese dioxide reference electrode to obtain the test potential results.

[0099] In saline-alkali soil, the potential fluctuation ranges of the natural potentials of the copper sulfate reference electrode, gel reference electrode, high-purity zinc reference electrode, graphite rod reference electrode, silver / silver chloride reference electrode and manganese dioxide reference electrode are ranked from small to large as follows: gel reference electrode 0.168, copper sulfate reference electrode 0.172, silver / silver chloride reference electrode 0.217, high-purity zinc reference electrode 0.238, graphite rod reference electrode 0.269, manganese dioxide reference electrode 0.486; In the control group soil, the potential fluctuation ranges of the control natural potentials of the copper sulfate reference electrode, gel reference electrode, high-purity zinc reference electrode, graphite rod reference electrode, silver / silver chloride reference electrode and manganese dioxide reference electrode were ranked from small to large as follows: manganese dioxide reference electrode 0.099, silver / silver chloride reference electrode 0.116, gel reference electrode 0.23, graphite rod reference electrode 0.252, copper sulfate reference electrode 0.278, high-purity zinc reference electrode 0.599.

[0100] The reference electrode ranked first in the potential fluctuation range of the natural potential in the saline-alkali soil can be assigned a value of 0.7, and the weight values ​​of other reference electrodes can be obtained according to the difference between the potential fluctuation ranges of the first and second natural potentials. Exemplarily, the weight value of the gel reference electrode is 0.7, and the difference in the potential fluctuation range between the natural potential of the gel reference electrode and the copper sulfate reference electrode is 0.004. Therefore, the weight value of the copper sulfate reference electrode is 0.7-0.004÷0.172×0.7=0.684, the weight value of the silver / silver chloride reference electrode is 0.7-0.049÷0.217×0.7=0.542, the weight value of the high-purity zinc reference electrode is 0.7-0.07÷0.238×0.7=0.494, the weight value of the graphite rod reference electrode is 0.7-0.101÷0.269×0.7=0.437, and the weight value of the manganese dioxide reference electrode is 0.7-0.318÷0.486×0.7=0.242.

[0101] The reference electrode ranked first in the potential fluctuation range of the control natural potential in the control group soil is assigned a value of 0.3, and the weight values ​​of other reference electrodes are obtained according to the difference between the potential fluctuation ranges of the first and second control natural potentials. Exemplarily, the weight value of the manganese dioxide reference electrode is 0.3, and the difference in the potential fluctuation range of the silver / silver chloride reference electrode and the manganese dioxide reference electrode relative to the natural potential is 0.017. Therefore, the weight value of the silver / silver chloride reference electrode is 0.3-0.017÷0.116×0.3=0.256, the weight value of the gel reference electrode is 0.3-0.131÷0.23×0.3=0.129, the weight value of the graphite rod reference electrode is 0.3-0.153÷0.252×0.3=0.118, the weight value of the copper sulfate reference electrode is 0.3-0.179÷0.278×0.3=0.107, and the weight value of the high-purity zinc reference electrode is 0.3-0.5÷0.599×0.3=0.05.

[0102] The reference electrode with a weight value greater than 0.5 in the saline-alkali soil can be used as the first target reference electrode, that is, the gel reference electrode with a weight value of 0.7, the copper sulfate reference electrode with a weight value of 0.684, and the silver / silver chloride reference electrode with a weight value of 0.542 as the first reference electrode; the reference electrode with a weight value greater than 0.11 in the control group soil can be used as the second target reference electrode, that is, the manganese dioxide reference electrode with a weight value of 0.3, the silver / silver chloride reference electrode with a weight value of 0.256, and the gel reference electrode with a weight value of 0.129 as the second target reference electrode.

[0103] The weight value of a target reference electrode is added to the weight value of a second target reference electrode, and the results are sorted from large to small. The first one is the gel reference electrode with a weight value of 0.7+0.129=0.829, the second one is the silver / silver chloride reference electrode with a weight value of 0.256+0.542=0.798, the third one is the copper sulfate reference electrode with a weight value of 0.684, and the fourth one is the manganese dioxide reference electrode with a weight value of 0.3.

[0104] Therefore, finally, the gel reference electrode with the largest weight value can be used as the target reference electrode.

[0105] Figure 3a The present invention provides a flow chart of a method for determining a reference electrode according to soil data. The electrode testing device in the method for determining a reference electrode according to soil data also includes a soil detector, such as Figure 3a As shown, according to the potential fluctuation range of the natural potential, a target reference electrode that meets the potential fluctuation range requirement is determined in the reference electrode, including:

[0106] S301, obtaining a soil detection result of a soil detector detecting a test soil, where the soil detection result represents soil data of the test soil;

[0107] S302, determining the corresponding relationship between soil data and natural potential according to the natural potential of the reference electrode and the soil detection result;

[0108] S303. Determine a target reference electrode that meets the potential fluctuation range requirement among the reference electrodes according to the corresponding relationship between the soil data and the natural potential and the potential fluctuation range of the natural potential.

[0109] Among them, a soil detector can be used to detect soil samples, record the soil temperature, humidity, pH value, ion concentration (such as potassium, sodium, calcium, etc.) and other soil data (such as organic matter content, conductivity, etc.), and store the processed soil data in the data recording system. According to the natural potential of the reference electrode during the potential detection process and the soil data obtained in real time during the potential detection process, the corresponding relationship between the soil data and the natural potential is determined. Specifically, statistical methods (such as regression analysis, correlation analysis, etc.) are used to analyze the relationship between soil data and natural potential, determine the degree of influence of various soil parameters (temperature, humidity, pH value, ion concentration, etc.) on the natural potential, and describe the corresponding relationship between soil data and natural potential by establishing a mathematical model or empirical formula.

[0110] In the embodiment of the present application, the corresponding relationship between soil data and natural potential is determined according to the natural potential of the reference electrode and the soil detection result, including:

[0111] Determine target soil data in the soil detection result, where the detection time of the target soil data corresponds to the test time of the natural potential in the test potential result;

[0112] According to the target soil data and the natural potential in the test potential results, the corresponding relationship between the soil data and the natural potential is determined.

[0113] Among them, the influence of various soil parameters (temperature, humidity, pH value, ion concentration, etc.) on the natural potential can be determined by analyzing the changes in the natural potential of the reference electrode and soil data (temperature, humidity, pH value, ion concentration, etc.) at the preset test time. Among them, the natural potential can be determined by analyzing the relationship between the natural potential of the reference electrode and the soil temperature, and the natural potential can be determined to be positively or negatively correlated with the soil temperature, and then the influence of temperature on the natural potential can be determined. For example, if it is observed that the natural potential shows a slight downward trend as the soil temperature increases, it can be concluded that the natural potential is negatively correlated with the soil temperature, indicating that the increase in temperature will lead to a decrease in the natural potential. If it is observed that the natural potential shows a slight upward trend as the soil temperature increases, it can be concluded that the natural potential is positively correlated with the soil temperature, indicating that the increase in temperature will lead to an increase in the natural potential. If it is observed that the natural potential shows a slight upward trend as the soil temperature decreases, it can be concluded that the natural potential is negatively correlated with the soil temperature, indicating that the decrease in temperature will lead to an increase in the natural potential. If it is observed that the natural potential also shows a slight downward trend as the soil temperature decreases, it can be concluded that the natural potential is positively correlated with the soil temperature, indicating that the decrease in temperature will also lead to a decrease in the natural potential.

[0114] Figure 3b The corresponding relationship diagram between the reference electrode and the soil test results provided in this application is as follows: Figure 3b As shown,

[0115] Among them, the soil type is saline-alkali soil, the reference electrode is copper sulfate reference electrode, and the soil data are moisture and conductivity.

[0116] The stability of the copper sulfate reference electrode under the change of soil moisture and conductivity in saline-alkali land during the test period can be analyzed through the trend graph of the natural potential of the copper sulfate reference electrode over time, the trend graph of soil moisture in saline-alkali land over time, and the trend graph of soil conductivity in saline-alkali land over time. Then, the natural electrode fluctuation range of the copper sulfate reference electrode in subsequent use is predicted through the historical humidity data and historical conductivity data of the saline-alkali land. If the predicted natural electrode fluctuation range of the copper sulfate reference electrode meets the preset requirements of the natural electrode fluctuation range of the saline-alkali land, the copper sulfate reference electrode is used as the target reference electrode.
