[0068] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0069] Insulating joints are devices installed in piping systems to electrically isolate different parts of the pipe, preventing the propagation of electric current. They are typically used to protect pipes from external current interference, such as the corrosive effects of direct current, thereby protecting the structural integrity of the pipes and extending their service life.

[0070] The resistivity of the anti-corrosion coating refers to the electrical resistance of the anti-corrosion material covering the surface of a pipe, specifically its ability to impede the flow of electric current. A high-resistivity anti-corrosion coating can effectively reduce the flow of current through the metal surface, thereby reducing the corrosion rate and protecting the metal structure from electrochemical corrosion.

[0071] A grounding electrode is an electrical device used to safely conduct current into the ground, typically made of a highly conductive metallic material. Its main function is to provide a low-impedance path through direct contact with the ground, effectively conducting excess or fault current in the electrical system to the ground, thereby protecting equipment and personnel from dangers caused by voltage instability or electrical faults.

[0072] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0073] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0074] To clearly understand the technical solution of this application, the existing technology solutions are first described in detail. In the prior art, pipelines face increasingly severe DC interference problems. This interference can cause potential fluctuations in the pipeline and accelerate corrosion, affecting its safety and service life. To address this challenge, insulating joints, as a key protective device, have been widely researched and applied. In the prior art, the installation position of the insulating joint is usually determined based on empirical rules or through rough calculations. The insulating joint is installed at the pipeline's installation location to achieve current isolation and protect the pipeline from potential fluctuations and pipeline corrosion.

[0075] However, existing technologies suffer from poor protective performance. They rely on experience or rough calculations to determine the installation location of insulating joints. This approach leads to a lack of precision in selecting the location of the insulating joints, making it unable to effectively cope with complex electromagnetic environment changes, ultimately resulting in poor protective performance.

[0076] Therefore, addressing the issue of poor protection in existing technologies, this research found that to solve this problem, the installation location of insulating joints can be determined by constructing and applying a computational model that considers multiple environmental factors, thereby improving pipeline protection: ① A precise computational model can be constructed using historical data to systematically analyze pipeline length, grounding electrode distance, soil resistivity, and anti-corrosion layer resistivity to optimize the installation location of insulating joints. ② Real-time acquisition of current environmental parameters and input into the computational model can dynamically determine the peak position of pipeline current, thus accurately locating the installation point of the insulating joint. ③ Combining historical and current data, a data-driven approach can be used to improve the model's prediction accuracy, achieving effective current isolation and protection.

[0077] Specifically:

[0078] By collecting and analyzing historical and real-time pipeline data, an accurate predictive model can be built. Using this model, the system can dynamically predict the peak location of pipeline current and provide recommendations for installing insulating joints, thereby achieving current isolation.

[0079] The method for determining the installation location of the insulating joint in this application systematically considers various factors such as pipeline length, grounding electrode distance, soil resistivity, and anti-corrosion layer resistivity when constructing the calculation model, thereby determining the installation location of the insulating joint. By inputting the current environmental conditions into the model, the peak position of the pipeline current can be accurately located, and the insulating joint can be installed at this position to achieve current isolation. This method overcomes the limitations of traditional methods that rely on experience or rough calculations, and improves the protection effect.

[0118] The technical effect of this solution in this embodiment is as follows: by refining and fitting the relationship between multiple historical parameters and historical pipeline currents, several specific fitting functions are generated. These functions quantify the impact of each parameter on the current distribution, and a more accurate calculation model is formed through comprehensive analysis. This model can effectively predict the location of current peaks, thereby optimizing the installation position of insulating joints, improving the electrical insulation performance of the pipeline system, reducing current leakage and corrosion problems, and enhancing the safety and reliability of the pipeline.

[0119] In one possible design, S204 inputs the current pipe length, current grounding electrode distance, current soil resistivity, and current anti-corrosion coating resistivity into the calculation model to obtain the current peak location, including:

[0120] S2041. Input the current pipeline length, current grounding electrode distance, current soil resistivity, and current anti-corrosion layer resistivity into the calculation model to obtain multiple current pipeline currents.

[0121] Specifically, these current parameters can be substituted into the previously constructed calculation model. This model, built based on historical data and a fitting function, can simulate current distribution under different parameter combinations. By inputting the current parameter values, the model can calculate the current values ​​at different locations in the pipeline, generating a set of current pipeline current data. This current data is used to identify the current peak location, i.e., the location of the maximum current, thereby determining the installation location of the insulating joint and ensuring the electrical performance and safety of the pipeline system.

[0122] S2042. Take the position corresponding to the maximum value of multiple current pipe currents as the current peak position.

[0123] Specifically, the computational model generates a series of current values ​​corresponding to different locations within the pipeline. These current values ​​can be iterated through using programming tools or data analysis software to identify the maximum value and its corresponding location. This location is the current peak location, used to determine the installation position of the insulating joint. This process ensures that the insulating joint is installed where the current is most concentrated, thereby optimizing the electrical insulation of the piping system, reducing current leakage and corrosion problems, and improving the safety and reliability of the system.

[0124] The technical effect of this solution in this embodiment is as follows: by inputting multiple current data into a pre-built calculation model, multiple current pipeline current values ​​are generated, and the maximum current value and its corresponding location are identified. This process can accurately locate the current peak position, thereby determining the installation position of the insulating joint. By optimizing the installation position, the electrical insulation performance of the pipeline system is improved, current leakage and corrosion problems are reduced, and the overall safety of the system is enhanced.

Figure 2 In this embodiment, in Figure 2 Based on the provided embodiments, the method for determining the installation position of the insulating joint is further explained. The method for determining the installation position of the insulating joint includes:

[0126] S301. Obtain multiple historical pipeline lengths, multiple historical grounding electrode distances, multiple historical soil resistivity, multiple historical anti-corrosion layer resistivity, and multiple historical pipeline currents within a preset time period in the past; wherein, the multiple historical pipeline lengths, multiple historical grounding electrode distances, multiple historical soil resistivity, multiple historical anti-corrosion layer resistivity, and multiple historical pipeline currents are respectively used to represent the pipeline length, the distance between the pipeline and the grounding electrode, the soil resistivity, the anti-corrosion layer resistivity, and the pipeline current within a preset time period in the past.

[0127] S302. A calculation model is constructed based on multiple historical pipeline lengths, multiple historical grounding electrode distances, multiple historical soil resistivity, multiple historical anti-corrosion layer resistivity, and multiple historical pipeline currents.

[0128] S303, obtain the current pipeline length, current grounding electrode distance, current soil resistivity, and current anti-corrosion layer resistivity.

[0129] S304. Input the current pipeline length, current grounding electrode distance, current soil resistivity, and current anti-corrosion layer resistivity into the calculation model to obtain the current peak position; where the current peak position refers to the position of the current maximum value of the pipeline.

[0130] S305. Determine the location of the current peak as the installation location of the insulating joint.

[0131] S301-S305 are similar to S201-S205, and will not be described again in this embodiment.

[0132] S306. Obtain the preset installation position of the insulating joint.

[0133] Specifically, the preset installation locations of insulating joints can be obtained by referring to engineering design specifications, historical installation data, or expert experience. These preset locations serve as benchmarks, compared to the peak current locations predicted by the computational model. By calculating errors and iteratively optimizing the model, the accuracy of the computational model can be improved, ensuring that the insulating joints are installed in effective positions, thereby optimizing the electrical performance and safety of the piping system.

[0134] S307. Calculate the error between the peak current location and the installation location of the insulating joint, and iteratively optimize the calculation model based on the error.

[0135] Specifically, the error can be quantified by calculating the distance or deviation between the two. Based on the calculated error, optimization algorithms, such as gradient descent, genetic algorithms, or other optimization techniques, are used to adjust and iterate the parameters of the computational model to reduce the error. This process is repeated until the error is less than a preset threshold. Through this iterative optimization, the accuracy and reliability of the computational model are improved, ensuring that the insulating joints are installed in the proper positions, thereby optimizing the electrical performance and safety of the piping system.

[0136] S308. The calculation model when the error is less than the preset threshold is the optimized calculation model.

[0137] Specifically, after each iteration of adjusting the calculation model parameters, the error between the peak current location and the preset insulation joint installation location is calculated and compared with a preset threshold. When the error is less than or equal to the threshold, the iteration process stops, and the calculation model at this point is considered the optimized model. This optimized model is used to ensure the accuracy and effectiveness of the insulation joint installation location, thereby improving the electrical performance and safety of the piping system and reducing current leakage and corrosion problems.

[0138] The technical advantage of this solution in this embodiment lies in obtaining a preset installation position of the insulating joint and calculating the error between it and the current peak position, thereby iteratively optimizing the calculation model. This process ensures that the calculation model can accurately predict the current peak position, thus optimizing the installation position of the insulating joint.

[0139] It should be noted that:

[0140] Laying horizontal zinc strips at the insulating joints reduces the impact of DC interference on the pipeline as the strips grow longer. The zinc strips significantly affect the pipeline potential on the side where they are laid, but have a smaller impact on the potential on the other side. Therefore, the zinc strips should be laid to cover the area with the most severe interference as much as possible.

[0141] Soil resistivity has a relatively small impact on the location of insulating joints, especially under high-resistivity anti-corrosion layers, where the influence of soil resistivity on the location of current peaks is almost negligible.

[0142] The distance between the grounding electrode and the pipeline has a significant impact on the location of the insulating joint. As the distance between the grounding electrode and the pipeline decreases, the DC interference experienced on the pipeline increases, and the peak current location moves closer to the grounding electrode. When the distance between the grounding electrode and the pipeline decreases, the insulating joint should be installed closer to the grounding electrode. For example, when the distance between the grounding electrode and the pipeline decreases from 31 km to 1 km, the installation position of the insulating joint may change by approximately 20 km.

[0143] As the pipe length increases, the pipe current increases, and DC interference becomes more severe. Furthermore, as the pipe length increases, the peak current location gradually moves closer to the grounding electrode; therefore, the location of the insulating joint should be close to the grounding electrode.
