Description

Technical Field

[0001] This invention relates to the field of pipeline safety management technology, and in particular to a method for analyzing the breakpoints in medium-pressure pipeline networks based on pipeline topology. Background Technology

[0002] Natural gas, as one of the city's basic energy sources, flows to thousands of households through gas pipelines. With the continuous expansion of gas users and the ongoing laying of new medium-pressure pipelines, the pipelines between residential areas are gradually being connected, forming a large network. Through this network, users at the end of the pipeline can receive gas from various pressure regulating stations. Because natural gas flows in the pipeline network according to fluid dynamics principles, the farther the end of the pipeline is from the pressure regulating station, the more bends and straight sections its gas pipeline passes through, making gas pressure more prone to fluctuations during peak consumption periods. Furthermore, the pipeline network contains numerous "discontinuities," meaning that the main gas pipelines laid as part of road construction have not formed effective loops. When users connect to such pipelines, the network's gas supply capacity can easily become insufficient.

[0003] In existing technologies, connecting "disconnected" pipelines to the main pipeline network closer to the gas source can significantly improve the gas supply capacity and ensure safe and stable operation of the pipeline network. For example, gas companies can use pipeline simulation software combined with monitoring data to simulate the operation of the pipeline network and analyze existing pipeline disconnection problems. This technology relies on three elements and processes: establishing hydraulic and thermodynamic relationships in the pipeline system based on physical principles; establishing a pipeline flow simulation model using mathematical methods; and developing computer software using computer technology to form the core technology of pipeline simulation. However, this modeling technology for analyzing pipeline disconnection locations requires numerous input parameters, complex model building, and a high level of technical expertise. When using small-to-medium-sized gas simulation software to analyze the location of medium-pressure pipeline disconnections, it often incurs high technical costs. Furthermore, this modeling technology cannot quickly analyze pipeline disconnections when user information is incomplete or pipeline end-pressure monitoring data is incomplete.

[0004] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a method for analyzing medium-pressure pipeline network breakpoints based on pipeline network topology, addressing the aforementioned deficiencies of existing technologies. This method addresses the issues of existing modeling techniques for analyzing pipeline breakpoint locations requiring numerous input parameters, complex model building, and high levels of technical expertise. Furthermore, using small-to-medium-sized gas simulation software to analyze medium-pressure pipeline breakpoint locations often incurs high technical costs. Additionally, this modeling technique cannot quickly analyze pipeline breakpoints when user information is incomplete or pipeline end-pressure monitoring data is inadequate.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0018] Arrange the shortest straight-line distances in ascending order to obtain the first ranking.

[0019] In one implementation, obtaining the ID and location information of each voltage regulating station, and determining a second ranking of the plurality of blocking objects based on the ID and location information of the blocking objects and the voltage regulating stations, includes:

[0020] Obtain the ID and location information of each plug and pressure regulating station. Based on the location information of each plug and pressure regulating station, iterate and calculate the shortest pipeline path length from each plug to the pressure regulating station.

[0021] Arrange the shortest pipeline path lengths in ascending order to obtain the second ranking.

[0022] In one implementation, determining the comprehensive ranking of the plurality of blocking structures based on the first ranking and the second ranking includes:

[0023] Calculate the average ranking of the plurality of blocking objects based on the first ranking and the second ranking, and use the average ranking as the comprehensive ranking of the plurality of blocking objects.

[0024] In one implementation, after determining the degree of fault risk in the medium-pressure pipeline network based on the comprehensive ranking, the process includes:

[0025] The risk level of each blockage location is obtained, and the repair sequence of the medium-pressure pipeline network breaks is determined based on the risk level of the breaks, wherein the repair sequence is proportional to the risk level of the breaks at the location of the blockage.

[0026] Secondly, embodiments of the present invention also provide a medium-pressure pipeline network breakpoint analysis device based on pipeline network topology, wherein the device includes:

First, a simplified first pipeline topology diagram is used to obtain the objects to be analyzed. A second pipeline topology diagram is then constructed based on these objects. Next, the ID and location information of the objects to be analyzed are obtained. Based on this information, a comprehensive ranking of several blockages is calculated. Finally, the degree of breakpoint risk in the medium-pressure pipeline is determined based on the comprehensive ranking. On one hand, this invention simplifies the objects to be analyzed in the original pipeline topology diagram, retaining only characteristic points such as blockages, pressure regulating stations, and pipelines as the objects to be analyzed. This constructs a new pipeline topology diagram. Then, by obtaining the distance ranking between objects with different IDs in the new topology diagram, the degree of breakpoint risk at the location of the medium-pressure pipeline is determined. This method provides a rapid way to analyze and locate pipeline breakpoints even when pipeline user information is incomplete or pipeline end-pressure monitoring data is incomplete. On the other hand, in this invention, each different ID of the object to be analyzed in the new pipeline network topology diagram is assigned a location information. Therefore, after determining the degree of risk of a break in the location of the medium-pressure pipeline network, the specific location of the original pipeline network break can be accurately located based on the ID information and location information of the object to be analyzed. Therefore, the medium-pressure pipeline network break analysis method based on pipeline network topology provided by this invention can achieve rapid analysis and location of pipeline network break risks.

[0039] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] This embodiment provides a method for analyzing the breakpoints in medium-pressure pipelines based on pipeline topology. Specifically, a first simplified pipeline topology diagram is first used to identify the objects to be analyzed within the simplified diagram. A second pipeline topology diagram is then constructed based on these objects. Next, the ID and location information of the objects to be analyzed are obtained. Based on the ID and location information, a comprehensive ranking of several blockages is calculated. Finally, the degree of breakpoint risk in the medium-pressure pipeline is determined based on the comprehensive ranking. On one hand, this embodiment simplifies the objects to be analyzed in the original pipeline topology diagram, retaining only characteristic points such as blockages, pressure regulating stations, and pipelines as the objects to be analyzed. This constructs a new pipeline topology diagram. Then, by obtaining the distance ranking between objects with different IDs in the new topology diagram, the degree of breakpoint risk at the location of the medium-pressure pipeline is determined. This method provides a rapid way to analyze and locate pipeline breakpoints even when pipeline user information is incomplete or pipeline end-pressure monitoring data is incomplete. On the other hand, in this embodiment, each different ID of the object to be analyzed in the new pipeline topology diagram is assigned a location information. Therefore, after determining the degree of risk of the break point at the location of the medium-pressure pipeline, the specific location of the original pipeline break point can be accurately located based on the ID information and location information of the object to be analyzed. Therefore, the medium-pressure pipeline break point analysis method based on the pipeline topology structure provided in this embodiment can achieve rapid analysis and location of pipeline break point risks.

[0041] For example, in this embodiment, each object to be analyzed is assigned its own corresponding ID and location information in the newly constructed pipeline topology map. When this embodiment calculates the comprehensive ranking of several plugs, it obtains the ID and location information of the objects to be analyzed in advance, such as the ID and location information of each plug, pipe segment, and pressure regulating station. Then, it further determines the ranking of the shortest straight-line distance D1 from the plug to the pipe segment, the ranking of the shortest pipeline path length D2 from the plug to the pressure regulating station, and the comprehensive ranking of the D1 and D2 rankings. The comprehensive ranking is used as the basis for determining the degree of risk of the breakpoint. When this embodiment uses the comprehensive ranking derived from distance relationships to determine the degree of risk of the breakpoint, it realizes the problem of quickly analyzing pipeline breakpoints when the number of pipeline user information is unclear and the pressure monitoring data at the end of the pipeline is incomplete. Finally, after determining the risk level of the break point in the medium-pressure pipeline network based on the comprehensive ranking, this embodiment can also quickly and accurately locate the specific location of the original pipeline network break point by using the pre-allocated location information corresponding to each object to be analyzed. For example, the location information corresponding to the sealing object is coordinates (X0, Y0), and the starting coordinates of the location information corresponding to each pipe segment are (X1, Y1) and the ending coordinates are (X2, Y2).

[0042] Exemplary methods

[0043] The medium-pressure pipeline network breakpoint analysis method based on pipeline topology in this embodiment can be applied to terminal devices, which can be intelligent product terminals such as mobile phones, tablets, and computers. In this embodiment, the terminal device can be an external device connected to the medium-pressure pipeline network breakpoint analysis device based on pipeline topology, or it can be a device built into the medium-pressure pipeline network breakpoint analysis device based on pipeline topology. Figure 1 As shown in the figure, the medium-pressure pipeline network discontinuity analysis method based on pipeline network topology in this embodiment includes the following steps:

[0044] Step S100: Simplify the first pipeline network topology diagram, obtain the object to be analyzed in the simplified first pipeline network topology diagram, and construct the second pipeline network topology diagram based on the object to be analyzed.

[0045] In the specific implementation process, the first pipeline topology map is a common urban gas pipeline topology map, and the second pipeline topology map is a newly constructed gas pipeline topology map.

[0046] Since common urban gas pipeline networks are mainly composed of pipes and pipe nodes, which mainly include valves, tees, reducers, straight sections, bends, and plugs (pipe ends), the pipeline topology diagram formed by these pipe nodes and pipe segments often involves too many elements, making it difficult to analyze the location of pipeline breaks. Therefore, this embodiment simplifies the first pipeline topology diagram, determines the object to be analyzed, and constructs a second pipeline topology diagram with appropriate elements. Specifically, the pipe segments are divided into segments with different diameters, such as 110mm, 160mm, 200mm, and 260mm, due to their different diameters. In this embodiment, the pipe diameter to be analyzed is first determined, and then the pipe network composed of pipe segments smaller than the pipe diameter to be analyzed is removed, that is, the interfering pipe segments are removed in advance. Virtual connection points are used to replace the pipe network composed of the pipe diameter to be analyzed. The pipe nodes are further simplified, and only tees, plugs, and pressure regulating stations are retained. Therefore, the objects to be analyzed in the first pipe network topology diagram also include pipe segments, virtual connection points, tees, plugs, and pressure regulating stations. Finally, these objects to be analyzed are merged to construct the second pipe network topology diagram.

[0047] Therefore, as Figure 2 As shown in the diagram, the second pipeline topology diagram of this embodiment includes a pressure regulating station, pipe sections, virtual connection points, tees, and plugs.

[0048] Step S200: Obtain the ID information and location information of the object to be analyzed, and calculate the comprehensive ranking of several blocking objects based on the ID information and location information.

[0049] Specifically, each object to be analyzed in the second pipeline network topology diagram has its own corresponding ID information. For example, each plug has its corresponding ID number, each pressure regulating station has its corresponding ID number, each pipe segment, and each virtual connection point also have their corresponding ID number. Furthermore, this embodiment assigns corresponding location information to each object to be analyzed. For example, the location information corresponding to each plug is coordinates (X0, Y0), and the starting coordinates of the location information corresponding to each pipe segment are (X1, Y1), and the ending coordinates are (X2, Y2).

[0050] Preferably, this embodiment combines the coordinates of pipe segments and nodes with the topology, so that the analysis results do not require secondary conversion. The specific location of the pipeline break can be quickly located in subsequent steps using the ID number and coordinates of the blockage.

[0051] In one implementation, this embodiment obtains the ID information and location information of the object to be analyzed, and calculates the comprehensive ranking of several blocking devices based on the ID information and location information, including the following steps:

[0052] Step S201: Obtain the ID information and location information of the sealing material and the pipe segment; determine the first ranking of the sealing materials based on the ID information and location information of the sealing material and the pipe segment.

[0053] Step S202: Obtain the ID information and location information of the pressure regulating station, and determine the second ranking of the plurality of blocking objects based on the ID information and location information of the blocking objects and the pressure regulating station;

[0054] Step S203: Based on the first ranking and the second ranking, determine the comprehensive ranking of the plurality of blocking objects.

[0055] In the specific implementation process, by using the location information between the sealing objects and pipe segments of each ID, the distance between the location of each sealing object and the on-site excavation distance of the "breakpoint repair connection" can be determined. By using the location information between the sealing objects and the pressure regulating station of each ID, the gas pressure and flow velocity at the location of each sealing object can be determined. Then, by comprehensively considering the gas pressure and flow velocity at the location of each sealing object and its distance from the on-site excavation distance of the "breakpoint repair connection", the degree of breakpoint repair of each sealing object can be comprehensively judged.

[0056] In one implementation, step S201 of this embodiment specifically includes:

[0057] Step S211: Obtain the ID information and location information of each sealing object and pipe segment. Based on the location information of each sealing object and pipe segment, iterate and calculate the shortest straight-line distance from each sealing object to the pipe segment.

[0058] Step S212: Arrange the shortest straight-line distances in ascending order to obtain the first ranking.

[0059] like Figure 3 As shown, in this embodiment, a rectangular coordinate system is constructed with the coordinate position (X0, Y0) of the plug as the origin. A circle is drawn with (X0, Y0) as the center and a specified radius until the drawn circle intersects with any pipe segment. The ID information and position information of the pipe segment are recorded to determine the straight-line distance D1 from the plug to the nearest pipe. Then, the radius is expanded until the drawn circle intersects with all pipe segments. The ID information and position information of all pipe segments are recorded. The position information of each pipe segment includes the starting coordinate position (X1, Y1) and the ending coordinate position (X2, Y2). Then, the mathematical formula of the shortest distance from a point to a line segment in the rectangular coordinate system is used to calculate the shortest straight-line distance D1 from each plug to the pipe segment. The shortest straight-line distance D1 represents the on-site excavation distance from the location of each plug to the "breakpoint repair connection". The smaller the value of D1, the shorter the on-site excavation distance and the lower the corresponding excavation cost.

[0060] For example, firstly, after traversing the calculations, if the distance from the first ID blockage to the first ID pipe segment is found to be 35m, the distance from the first ID blockage to the second ID pipe segment is 60m, and the distance from the first ID blockage to the third ID pipe segment is 72m, then since 35m < 60m < 72m, the distance of 60m from the first ID blockage to the first ID pipe segment is determined to be the shortest straight-line distance for the first ID blockage. Then, the shortest straight-line distances for the second ID blockage, the third ID blockage, and the fourth ID blockage are calculated, i.e., the shortest straight-line distance from each blockage to the pipe segment is calculated traversally.

[0061] Furthermore, in this embodiment, several shortest straight-line distances are arranged in ascending order to obtain a first ranking. For example, when the shortest straight-line distance of the first ID blockade is 60m, the shortest straight-line distance of the second ID blockade is 40m, and the shortest straight-line distance of the third ID blockade is 55m, since 40m < 55m < 60m, the first ranking order is: second ID blockade, third ID blockade, and first ID blockade.

[0062] In one implementation, step S202 of this embodiment specifically includes:

[0063] Step S221: Obtain the ID information and location information of each plug and pressure regulating station. Based on the location information of each plug and pressure regulating station, traverse and calculate the shortest pipeline path length from each plug to the pressure regulating station.

[0064] Step S222: Arrange the shortest pipeline path lengths in ascending order to obtain the second ranking.

[0065] like Figure 4 As shown in the figure, the bold line segment represents the shortest pipeline path length D2 from the plug to the pressure regulating station. The shortest pipeline path length D2 indicates the gas pressure and flow velocity at the location of each plug. According to fluid mechanics principles, the longer the path of gas flowing from the gas source, the lower the flow velocity and pressure at the destination, and the greater the pressure loss along the way.

[0066] Specifically, this embodiment first obtains the ID and location information of each plug and pressure regulating station. Then, starting from the location of the plug, it calculates the shortest path from each plug to the pressure regulating station using shortest path solving algorithms, such as Dijkstra's algorithm, Bellman-Ford algorithm, SPFA algorithm, and Floyd algorithm. Finally, it iterates through the network to calculate the shortest pipeline path length from each plug to the pressure regulating station. The path length is the sum of the lengths of all pipe segments along the path. If the path from the plug to a pressure regulating station is blocked, the pipeline path length from the plug to that pressure regulating station is infinite. For example, after iterative calculation, the shortest pipeline path length for the plug with the first ID is 110m, for the plug with the second ID it is 82m, and for the plug with the third ID it is 55m.

[0067] Furthermore, in this embodiment, several shortest pipeline path lengths are arranged in ascending order to obtain a second ranking. For example, when the shortest pipeline path length of the first ID blockade is 110m, the shortest pipeline path length of the second ID blockade is 82m, and the shortest pipeline path length of the third ID blockade is 55m, since 55m < 82m < 110m, the second ranking order is: third ID blockade, second ID blockade, first ID blockade.

[0068] In one implementation, step S203 of this embodiment specifically includes:

[0069] Step S231: Calculate the average ranking of the plurality of blocking objects based on the first ranking and the second ranking, and use the average ranking as the comprehensive ranking of the plurality of blocking objects.

[0070] Since the first ranking represents the distance of each sealing element from the on-site excavation of the "breakpoint repair connection," and the second ranking represents the gas pressure and flow velocity at the location of each sealing element, this embodiment uses the average of the first and second rankings as the comprehensive ranking. This not only comprehensively considers the gas pressure and flow velocity at the location of each sealing element, as well as its distance from the on-site excavation of the "breakpoint repair connection," but also enables a more accurate assessment of the breakpoint risk level of each sealing element in subsequent steps.

[0071] Preferably, this embodiment can also superimpose or replace other considerations on the basis of the straight-line distance from the blockage to the nearest pipeline and the shortest pipeline path length from the blockage to the pressure regulating station. For example, the number of users carried in the pipeline area can be superimposed or replaced, thereby achieving good scalability in the content of the analysis method.

[0072] Step S300: Determine the degree of risk of breakpoints in the medium-pressure pipeline network based on the comprehensive ranking.

[0073] Specifically, in this embodiment, the ranking of the blocking object is determined based on the order of the overall ranking. The higher the ranking of the blocking object, the higher the risk level of the breakpoint at the location of the blocking object; the lower the ranking of the blocking object, the lower the risk level of the breakpoint at the location of the blocking object.

[0074] In one implementation, after step S300, this embodiment includes the following steps:

[0075] Step S400: Obtain the risk level of the break point at the location of each plug, and determine the repair sequence of the medium-pressure pipeline break point location based on the risk level of the break point, wherein the repair sequence is proportional to the risk level of the break point at the location of the plug.

[0076] Specifically, if the risk of a break at the location of the blockage is higher, priority should be given to repairing the break at that location and optimizing the pipeline structure.

[0077] In summary, this embodiment provides a method for analyzing the breakpoints in medium-pressure pipelines based on pipeline topology. Specifically, it first simplifies a first pipeline topology diagram, then obtains the objects to be analyzed from the simplified diagram, constructs a second pipeline topology diagram based on these objects, and then obtains the ID and location information of the objects. Based on the ID and location information, it calculates a comprehensive ranking of several blockages, and finally determines the degree of breakpoint risk in the medium-pressure pipeline based on the comprehensive ranking. On one hand, this embodiment simplifies the objects to be analyzed in the original pipeline topology diagram, retaining only characteristic points such as blockages, pressure regulating stations, and pipelines as the objects to be analyzed, thus constructing a new pipeline topology diagram. Then, by obtaining the distance ranking between objects with different IDs in the new topology diagram, it determines the degree of breakpoint risk at the location of the medium-pressure pipeline. This method provides a rapid way to analyze and locate pipeline breakpoints even when pipeline user information is incomplete or pipeline end-pressure monitoring data is incomplete. On the other hand, in this embodiment, each different ID of the object to be analyzed in the new pipeline topology diagram is assigned a location information. Therefore, after determining the degree of risk of the break point at the location of the medium-pressure pipeline, the specific location of the original pipeline break point can be accurately located based on the ID information and location information of the object to be analyzed. Therefore, the medium-pressure pipeline break point analysis method based on the pipeline topology structure provided in this embodiment can achieve rapid analysis and location of pipeline break point risks.
