Description

Technical Field

[0001] The present invention relates to the technical field of pipeline monitoring, in particular to a pipeline integrity evaluation and management system. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas (including associated gas produced by oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise. It is also called a gas transmission pipeline. Using natural gas pipelines to transport natural gas is a way to transport a large amount of natural gas on land. However, due to the flammability and explosion of natural gas, as well as the "invisibility" and concealment of underground pipelines, once a natural gas pipeline leaks, it may cause a fire or explosion, which will cause great harm to the lives and property of urban residents. Therefore, regular pipeline inspections are particularly important.

[0003] At present, the domestic inspection of natural gas pipelines mainly adopts the method of manual line inspection, that is, inspectors carry gas alarms and travel many miles every day to inspect the natural gas pipeline lines along the line, and inspect each pipeline one by one to find out whether there are abnormal sections, so as to ensure the safety of the gas pipeline.

[0004] However, the above inspection method cannot achieve rapid and effective unified scheduling and management of the inspection results, making it difficult to prioritize potential risks of natural gas pipelines. Summary of the invention

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Please refer to Figure 1As shown in the figure, the present invention provides a pipeline integrity evaluation management system, which includes a synchronous input module 1. The synchronous input module 1 is configured to receive the abnormal positions and monitoring data of the natural gas pipeline marked corresponding to the pipeline inspection map. Among them, the synchronous input module 1 includes a processing matrix 2, an estimation module 3, a comparison module 4, and an evaluation module 5. In the processing matrix 2, an inspection model constructed from the pipeline inspection map is set. And in the set inspection path 7, at least the abnormal position of the natural gas pipeline marked corresponding to the pipeline inspection map and the first monitoring data are used as the basic input data to obtain the first fusion result at the first moment in the processing matrix 2; and the second monitoring data obtained from at least one inspection path 7 adjacent to the abnormal position is used as the basic input data to obtain the second fusion result at the second moment in the processing matrix 2. The estimation module 3 is configured to: receive the first fusion result at the first moment, and calculate the first disturbance estimate of at least one inspection path 7 adjacent to the abnormal position based on the first fusion result. The first disturbance estimate is obtained in the estimation model based on the first fusion result. The comparison module 4 is configured to: take the abnormal position as the measurement reference point, call at least one second fusion result at the second moment respectively according to the distance from the abnormal position, and compare the second fusion result at the second moment with the set reference threshold to obtain the second disturbance estimate of the second fusion result. The evaluation module 5 is configured to: evaluate whether the monitoring data of the abnormal position of the pipeline is effective according to the difference between the first disturbance estimate and the second disturbance estimate. In the above, all inspection data of the natural gas pipeline can be centrally processed, so as to realize fast and effective unified scheduling management of the inspection results, facilitate the priority investigation of potential risks of the natural gas pipeline according to the inspection results, and significantly improve the inspection efficiency and the preparation time limit of the natural gas pipeline maintenance plan compared with the existing manual inspection processing method.

[0050] Further, the processing matrix 2 includes a number of parallel processing units. Each processing unit has a number of parallelly extracted extraction nodes and a processor. The extraction nodes are used to: extract the geographical coordinates of any position from the pipeline inspection map; extract the topological node identifier representing the inspection path 7 from the inspection path 7 of the inspection model; and extract the real-time data collected by the sensor from the sensor in real time. The processor sets the fusion dimension of the fusion data according to the extraction nodes, and obtains the corresponding first fusion result at the first moment and / or the second fusion result at the second moment according to the fusion dimension, providing high-quality data support for subsequent data analysis and decision-making.

[0051] In the above, when the processor sets the fusion dimension, it uses a unique data conversion algorithm. For example, the processor converts the geographical coordinates of any position extracted from the pipeline inspection map into a hash value or area code that is convenient for storage, calculation, and analysis through an advanced hash algorithm or an efficient area coding method, and uses the hash value or area code as the first dimension of the fusion result, which can provide an accurate geographical location index for the data; serializes the topological node identifiers of the inspection path 7 to obtain a string representing the inspection path 7, and uses the string as the second dimension of the fusion result, which helps to clearly sort out the correspondence between the data and the inspection path 7; classifies the monitoring data according to the type of sensor, and obtains the analog quantity of the real-time data collected by each sensor. Using the set time unit as the serial number and the average value of the analog quantity of the real-time data of each sensor within the set time unit as the third dimension of the fusion result can effectively reflect the comprehensive characteristics of the sensor data at different time nodes.

[0052] Furthermore, the processing node operates under the set control logic; the control logic includes: a first logic set for the basic tasks of the processing node, and a second logic for extracting the real-time sensor data under the first logic; among them, the basic tasks of the processing node include a first basic task of extracting the geographical coordinates of any position in the pipeline inspection map and a second basic task of extracting the topological node identifiers corresponding to the inspection path 7 of the inspection model. These two basic tasks are the cornerstones of the entire data processing process. It should be noted that the basic tasks of the processing node are not randomly started, but are generated based on the key trigger information of the abnormal position of the natural gas pipeline received by the synchronous input module 1, ensuring that the data processing work always focuses on the abnormal situation, improving the processing efficiency and pertinence.

[0053] Furthermore, the abnormal position of the natural gas pipeline is obtained by the following method:

[0054] Construct an inspection model based on the natural gas pipeline inspection map, generate a pipeline inspection map and inspection tasks in the inspection model; divide the pipeline inspection map into several inspection paths 7 according to the gas transmission parameters of the natural gas pipeline in the inspection model, and configure the topological node identifiers of the inspection path 7 for subsequent data tracking and analysis. Such as Figure 2As shown, during the actual deployment of each inspection path 7, in order to achieve comprehensive and real-time monitoring of the pipeline operation status, a set of data collectors 6 are set every 15 - 20 m on each inspection path 7, and the alarm threshold for the corresponding inspection path 7 is set; the actual gas transmission parameters collected by the data collectors 6 are compared with the alarm threshold of the corresponding inspection path 7 through a comparison unit to generate an alarm instruction and upload it to the inspection model to trigger the alarm 8 for early warning. The inspection model marks the abnormal position and early warning level of the natural gas pipeline according to the alarm instruction level of the inspection path 7 and the coordinate corresponding to the inspection path 7 in the pipeline inspection map, enabling the inspection personnel to effectively monitor the potential risks of the entire natural gas pipeline based on the inspection results real-time feedback in the pipeline inspection map. Compared with the traditional fixed-point and regular inspection methods, the inspection accuracy and reliability are greatly improved, potential risks can be detected in a timely manner and effective measures can be taken to ensure the safe and stable operation of the natural gas pipeline.

[0055] Furthermore, the inspection path 7 in the pipeline inspection map has different indications according to the gas transmission flow rate of the natural gas pipeline, and the indication dynamically changes the indicated and displayed state according to the change in the flow rate; among them, the indication is realized by an indication program to dynamically change the indicated and displayed state according to the change in the flow rate; the indication program is configured to have several indication areas, and each indication area represents a unit amount of flow rate change. When the gas transmission flow rate changes, the indication areas in the indication program are combined according to the corresponding gas transmission flow rate according to the set logical control rules to achieve the corresponding flow indication.

[0056] In the above, the display state of inspection path 7 in the pipeline inspection map is composed of multiple display bars arranged side by side and continuously. The number of display bars is set in one-to-one correspondence with the number of indication areas. The display bars are used to divide the gas transmission flow rate of the natural gas pipeline into corresponding unit amounts, so as to represent the flow rate change of the natural gas pipeline under the corresponding unit amounts through different indication areas. In the above, the set logical control rule is: for each increase of one unit amount in the gas transmission flow rate, the indication state of inspection path 7 in the pipeline inspection map lights up one indication area correspondingly, so as to thicken the width of inspection path 7 by one unit amount and display it in the pipeline inspection map; for each decrease of one unit amount in the gas transmission flow rate, the indication state of inspection path 7 in the pipeline inspection map extinguishes one indication area correspondingly, so as to reduce the width of inspection path 7 by one unit amount and display it in the pipeline inspection map; among them, the change of the indication area is a continuous change, and it changes sequentially from one side of inspection path 7 to the other side, which is convenient to identify the gas transmission flow rate of the natural gas pipeline according to the display width of inspection path 7 in the pipeline inspection map, so as to arrange the inspection operation priority of inspection path 7 according to the gas transmission flow rate of the natural gas pipeline during the inspection process; for example, when the gas transmission flow rate of the natural gas pipeline is large, its leakage will cause greater potential safety hazards, and the inspection can be arranged preferentially; and, it is possible to judge whether there is a leakage in the corresponding inspection path 7 according to the difference between the actual display width and the preset width of inspection path 7, so as to only perform inspection operations on the inspection path 7 with a difference change when the inspection task is heavy, thereby being able to reasonably arrange the inspection tasks and reduce the inspection intensity.

[0057] Further, the method for the data collector 6 to collect the actual gas transmission parameters of the natural gas pipeline is as follows:

[0058] 1) Collect the actual gas transmission flow rate of the natural gas pipeline through a gas flow meter, and compare the actual gas transmission flow rate with the alarm threshold of inspection path 7 through a comparison unit to generate a first alarm instruction.

[0059] 2) Collect the actual gas transmission pressure of the natural gas pipeline through a gas pressure sensor, and compare the actual gas transmission pressure with the alarm threshold of inspection path 7 through a comparison unit to generate a second alarm instruction.

[0060] 3) Collect the actual gas transmission temperature of the natural gas pipeline through a temperature sensor, and compare the actual gas transmission temperature with the alarm threshold of inspection path 7 through a comparison unit to generate a third alarm instruction.

[0061] In the above, the first alarm instruction, the second alarm instruction, and the third alarm instruction are coupled to the alarm 8 on the inspection path 7, so that the alarm instructions on the inspection path 7 have several alarm levels. Specifically, the alarm levels of the alarm instructions on the inspection path 7 are at least set as follows: when any one of the first alarm instruction, the second alarm instruction, and the third alarm instruction shows an abnormality, the alarm level of the inspection path 7 is set to mild; when any two of the first alarm instruction, the second alarm instruction, and the third alarm instruction show an abnormality, the alarm level of the inspection path 7 is set to moderate; when the first alarm instruction, the second alarm instruction, and the third alarm instruction all show an abnormality, the alarm level of the inspection path 7 is set to severe.

[0062] Furthermore, the alarm 8 is configured with alarm signals of different warning levels based on each alarm level of the inspection path 7; for each abnormal section of the natural gas pipeline on the inspection path 7 in the pipeline inspection map, a uniquely determined display symbol is respectively configured for alarm signals of different warning levels, and the display symbol is dynamically adjusted based on the real-time change of the warning level of the alarm signal corresponding to the abnormal section of the natural gas pipeline on the inspection path 7 in the pipeline inspection map.

[0063] Exemplarily, in the above, when the alarm level of the alarm instruction on the inspection path 7 is mild, the alarm signal of the alarm 8 tends to diverge, and the display symbol of the abnormal section of the natural gas pipeline corresponding to the inspection path 7 in the pipeline inspection map is displayed in green. When the alarm level of the alarm instruction on the inspection path 7 is moderate, the alarm signal of the alarm 8 tends to concentrate, and the display symbol of the abnormal section of the natural gas pipeline corresponding to the inspection path 7 in the pipeline inspection map is displayed in yellow. When the alarm level of the alarm instruction on the inspection path 7 is severe, the alarm signal of the alarm 8 tends to be dense, and the display symbol of the abnormal section of the natural gas pipeline corresponding to the inspection path 7 in the pipeline inspection map is displayed in red. It should be noted that the alarm signal of the alarm 8 tending to diverge, concentrate, and be dense refers to the alarm frequency of the alarm signal, and its alarm frequency becomes more frequent in turn from divergence to concentration and density. During the inspection operation, the degree of dispersion of the alarm signal of the alarm 8 is used to indicate that there is an abnormality in the natural gas pipeline for the inspection personnel, and different colors are used in the pipeline inspection map to represent the corresponding warning levels, which can intuitively reflect the actual situation of the abnormal section of the natural gas pipeline in the inspection path 7, enabling the inspection personnel to prioritize the maintenance plans for multiple abnormal sections of the natural gas pipeline according to the warning level of the alarm signal, and giving priority to checking the abnormal section of the natural gas pipeline with a severe warning level of the alarm signal, thereby reducing the risk of casualties and property losses.
