Description

Technical Field

[0001] This invention relates to a gas pipeline monitoring method and system, belonging to the field of data management technology. Background Technology

[0002] Monitoring gas pipeline risks is a crucial aspect of ensuring household and public safety. Gas pipeline networks consist of high-pressure main pipelines, medium- and low-pressure branch pipelines, and user access pipelines. High-pressure main pipelines connect storage and distribution stations to urban areas, responsible for long-distance natural gas transportation. These pipelines have large diameters and are mostly made of seamless steel. High-pressure main pipelines are resistant to high pressure, bear the main transport burden, and require high pressure stability; they are often equipped with sectional valves and emergency shut-off devices. Medium- and low-pressure branch pipelines include medium-pressure and low-pressure pipelines. High pressure is reduced to medium- and low pressure by regional pressure regulating stations before being distributed to neighborhoods, forming a tree-like or ring-like layout to improve gas supply reliability. Medium-pressure sections commonly use PE plastic pipes or corrosion-resistant steel pipes, while low-pressure sections mostly use PE pipes or ductile iron pipes. User access pipelines are the final section of the pipeline connecting the neighborhood to the community or household.

[0003] The standards for monitoring high-pressure main pipelines, medium- and low-pressure branch pipelines, and user access pipes are inconsistent. Traditional methods for monitoring gas pipeline networks often rely on a combination of weather temperature and gas leak concentration, making it difficult to comprehensively understand the overall layout, equipment distribution, and operational status of gas pipelines. Therefore, it is necessary to propose a gas pipeline monitoring method and system to address the problem that traditional gas pipeline monitoring methods cannot comprehensively monitor different types of gas pipelines. Summary of the Invention

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0010] like Figure 1 As shown, the gas pipeline monitoring method provided by the present invention includes: S100 receives network access applications from each gas pipeline monitor, forming a gas pipeline information monitoring network.

[0011] S200 analyzes each network access application to obtain the gas pipe monitor ID.

[0012] S300 retrieves monitoring information from each gas pipeline monitor ID within the gas pipeline information monitoring network.

[0013] S400, select a gas pipe monitor ID.

[0014] S500 obtains the type and geographical coordinates of the target gas pipeline based on the gas pipeline monitor ID.

[0015] The S600 uses the monitoring information of the selected gas pipeline monitor ID to obtain the operating data of the target gas pipeline.

[0016] S700, find the real-time weather data for the geographical coordinates of the gas pipe monitor ID.

[0017] The S800 uses real-time weather and operational data to determine the operational risk level of the monitored gas pipeline.

[0018] S900, return to the previous step of selecting a gas pipe monitor ID, until all gas pipe monitor IDs have been selected.

[0019] S910 feeds back the operational risk level of each monitored gas pipeline to the gas pipeline information monitoring network.

[0020] Specifically, by managing each gas pipeline monitor, a gas pipeline information monitoring network can be formed. The "Monitoring Equipment Number" input box allows maintenance personnel to enter the monitoring equipment number to search. "Region Location" is a drop-down menu or input box where maintenance personnel can select or enter the region where the monitoring equipment is located. "Region" indicates the district to which the monitoring equipment belongs. "Equipment Current Operating Status" indicates the current operating status, such as alarm active, online, or high alert. "Equipment Type" indicates the type of monitoring equipment, such as pressure regulating box, valve well, or inlet pipe. Maintenance personnel can query information for the monitoring equipment with the entered number. The "Monitoring Equipment Number ID" column headers represent the monitoring equipment's number or ID. The "Monitoring Equipment Name" column headers represent the name of the monitoring equipment. The "Location" column headers represent the specific location of the monitoring equipment. The "Status" column headers represent the current status of the monitoring equipment. The "History Records" column headers contain historical status records or events of the monitoring equipment. The "Operations" column headers contain options for operating the monitoring equipment, such as viewing details or monitoring data.

[0021] In the gas pipeline information monitoring network, the monitoring information of each gas pipeline monitor ID can be retrieved by selecting a gas pipeline monitor ID, searching for the real-time operating data and geographical coordinate information of the gas pipeline monitor ID based on the system time, generating a timestamp based on the system time, assigning the timestamp to the real-time operating data, mapping the geographical coordinate information to the gas pipeline monitor ID, and returning to the previous step of selecting a gas pipeline monitor ID, until all gas pipeline monitor IDs have been selected.

[0022] The gas pipe monitor ID corresponds to a gas pipe monitor that sends monitoring information to the server. This monitoring information for the gas system or pipeline network includes pressure, flow rate, and leakage concentration. The gas pipe monitor object type lists the types of objects monitored in the system, such as different gas appliances or pipeline sections.

[0023] The geographic coordinates of the target gas pipeline can display regional information, such as Ping District A, Province Q, and Country K. Weather data can be obtained using these coordinates, including current weather conditions, such as maximum and minimum temperatures, e.g., 16 to 32 indicates a temperature range of 16°C to 32°C. Weather conditions are briefly described, such as thunderstorms. Wind direction and force show the wind direction and force level, e.g., northeast wind 3 to 4 indicates a northeast wind with a force of 3 to 4. Update time is the time the weather information was last updated, e.g., updated at 13:59 today. The warning area lists the areas covered by the warning. The warning level indicates the severity level of the warning, divided into Level 1, Level 2, etc. The warning name provides the specific name of the warning, e.g., lightning level 2 warning.

[0024] The operational risk level of each monitored gas pipeline is fed back to the gas pipeline information monitoring network. This network displays alarm statistics for different monitored objects, such as pressure regulating boxes (cabinets) and valve wells, stations, pipeline inspection sites, residential users, and industrial users. Methane concentration data is displayed, and a detailed alarm list is provided, including serial number, alarm object, type, time, and methane concentration value. Risk statistical analysis provides statistical analysis of risk factors in the gas system, helping to identify potential problem areas. Alarm statistical analysis analyzes alarm event data, including alarm frequency, type, and cause. Pipeline network statistical analysis statistically analyzes the overall performance and status of the gas pipeline network, including usage efficiency and maintenance needs. Alarm review is a process or module used to review alarm events, confirm their validity, and take appropriate action.

[0025] This application relates to a gas pipeline monitoring method. By receiving network access applications from each gas pipeline monitor, a gas pipeline information monitoring network is formed. This network comprehensively assesses the risks at each node of the gas pipeline, provides visualized data displays, and quickly identifies potential safety hazards. The monitoring network retrieves monitoring information from each gas pipeline monitor ID to comprehensively understand the overall layout, equipment distribution, and operational status of the gas pipeline. It monitors the operational status of the gas pipeline in real time, promptly detecting anomalies. Based on the gas pipeline monitor ID, the method obtains the type and geographical coordinates of the target gas pipeline, retrieves real-time weather data for the geographical coordinates of the gas pipeline monitor ID, and views relevant gas pipeline information, including the type of monitored object, the monitored object itself, and abnormal gas consumption warnings, in order to promptly understand the pipeline's operational status. Based on real-time weather and operational data, combined with weather data, the system provides maintenance personnel with real-time weather warnings to help them prepare for severe weather in advance. It assesses the operational risk level of monitored gas pipelines, rigorously reviews and processes alarm information issued by the system to ensure accuracy and reliability, prevent false alarms and omissions, and feeds back the operational risk level of each monitored gas pipeline to the gas pipeline information monitoring network. Through the system's detection functions, gas pipelines are regularly inspected to ensure their safety and integrity. The system comprehensively, intuitively, and efficiently analyzes and effectively manages various data related to gas pipelines, thereby ensuring the safe operation of gas pipelines, timely response to potential risks, improving the management level and operational efficiency of urban gas pipelines, and guaranteeing the safe and stable operation of gas pipelines.

[0026] In one embodiment of this application, S100 includes: S111, receives network access applications from all gas pipe monitors.

[0027] S112, Select a gas pipe monitor for network access application.

[0028] S113, using the selected network access application, determines the communication protocol between the server itself and the gas pipe monitor.

[0029] S114 establishes a communication link between the server and the gas pipe monitor based on the communication protocol.

[0030] S115, return to the step of selecting a gas pipe monitor network access application, until all gas pipe monitor network access applications have been selected.

[0031] S116 utilizes the communication links of each gas pipeline monitor to form a gas pipeline information monitoring network.

[0032] Understandably, gas pipe monitors are IoT devices. They can generate a network access request through their built-in network protocol stack, establishing a communication link with the server. The gas pipe monitor uses AT commands to set the frequency, spreading factor, and device address. Two-way TLS authentication ensures the legitimacy of both the gas pipe monitor and the server, and JWT is used to generate a temporary token, thereby guaranteeing the security of communication between them.

[0033] By applying for network access from all gas pipeline monitors, a communication link can be established between the server and the gas pipeline monitors, generating a gas pipeline information monitoring network. This network displays risk distribution, showing the risk distribution for different stations and valve well types, such as F zone 13.4%, T zone 86.6%, etc. Different icons are used to identify different types of risks or facilities / equipment, such as PE ball valve wells and steel ball valve wells.

[0034] The gas pipeline information monitoring network can also display a location table (column headings indicating the specific location of the monitoring equipment), a status table (column headings indicating the current status of the monitoring equipment), a history table (column headings containing historical status records or events of the monitoring equipment), and an operation table (column headings containing options for operating the monitoring equipment, such as viewing details or monitoring data). It also includes the monitoring equipment's number, pressure regulating box, ball valve well, inlet pipe, and the name of an example monitoring equipment.

[0035] In one embodiment of this application, S100 further includes: S121, Select a gas pipeline monitor's network access application in the gas pipeline information monitoring network.

[0036] S122 invokes the communication protocol between the server itself and the selected gas pipe monitor.

[0037] S123, using the network access application and communication protocol of the gas pipe monitor, determines the monitoring level of the gas pipe monitor.

[0038] S124, determine whether the monitoring level of the gas pipe monitor matches the first monitoring level.

[0039] S125, if the monitoring level of the gas pipe monitor matches the first monitoring level, then assign the high-pressure pipe monitoring tag to the gas pipe monitor.

[0040] S126, If the monitoring level of the gas pipe monitor does not match the first monitoring level, then determine whether the monitoring level of the gas pipe monitor matches the second monitoring level.

[0041] S127, If the monitoring level of the gas pipe monitor matches the second monitoring level, then assign the medium and low pressure pipe monitoring tag to the gas pipe monitor.

[0042] S128, if the monitoring level of the gas pipe monitor does not match the second monitoring level, then determine that the monitoring level of the gas pipe monitor matches the third monitoring level, and assign the user access pipe monitoring tag to the gas pipe monitor.

[0043] S129, return to the step of selecting a gas pipe monitor network access application, until all gas pipe monitor network access applications have been selected.

[0044] Understandably, based on the communication protocol type, a corresponding identifier is prepared, and the device ID from the gas pipe monitor's network access application is obtained by calling the API. After obtaining the gas pipe monitor's device ID, it can be parsed and its format decomposed. The device ID contains nested hierarchical information, and detailed information can be viewed using the device manager to find the monitoring level of the gas pipe monitor corresponding to the device instance ID.

[0045] In this embodiment, the monitoring level of the gas pipe monitor is the first monitoring level, which means that the gas pipe monitor is responsible for monitoring the high-pressure pipe. The high-pressure pipe is a gas transmission pipeline close to the gas source section. The high-pressure pipe undertakes the task of high-pressure gas and high-flow transmission. When the temperature is too high, extra attention needs to be paid to the gas transmission safety of the high-pressure pipe.

[0046] If the gas pipe monitor is classified as Level 2, it means that the gas pipe monitor is responsible for monitoring the medium and low pressure pipes. The medium and low pressure pipes are the middle section of the gas pipeline network. One end of the medium and low pressure pipe is close to the high pressure pipe, and the other end is close to the user. There are a large number of pressure regulating cabinets and pressure regulating box valve wells in the medium and low pressure pipes. The pressure regulating cabinets are used to regulate the gas surge from the high pressure pipe, and the pressure regulating box valve wells are used to change the direction of the gas in the pipeline.

[0047] If the gas pipe monitor is classified as Level 3, it means that the gas pipe monitor is responsible for monitoring the user's access pipe. The user's access pipe has a complex and dense layout, and it is necessary to prevent the aging of the user's access pipe and gas leakage.

[0048] In one embodiment of this application, S200 includes: S210, Select a network access application. Specifically, this involves sequentially selecting a single unprocessed gas pipe monitor network access application as the current task object, and the server initiates a data extraction operation. First, the precise latitude and longitude coordinates of the actual deployment location of the monitor are extracted from the device registration information field of the network access application (i.e., the point data required by the algorithm). Simultaneously, the basic information of the gas pipeline segment to which the monitor is pre-registered is retrieved from the system's preset gas pipeline network database, clarifying the latitude and longitude coordinates of the two endpoints of the pipeline segment (i.e., the straight-line reference data required by the algorithm). After extraction, the server automatically verifies the validity of the three sets of coordinate data, checking for anomalies such as incorrect latitude and longitude formats or coordinates falling outside the pipeline planning area. Invalid network access applications are marked as pending correction and temporarily stored. Only valid applications retain the point and straight-line reference data to provide a compliant data source for subsequent algorithm calculations.

[0049] S220, based on the network access application, obtains the gas pipe monitor ID. Specifically, based on the basic geographic data verified by S210 and the selected network access application, the server first parses the core device identifier field in the application, extracts the unique gas pipe monitor ID composed of letters and numbers, and verifies the ID format (matching the system's preset device ID encoding rules) to ensure that the ID is not duplicated or tampered with. Then, it calls the built-in point-to-line distance and perpendicular distance calculation algorithm module, using the monitor deployment point coordinates extracted by S210 as the calculation base point and the straight line formed by the two ends of the corresponding pipeline segment as the baseline, to complete the calculation of spatial distance and perpendicular distance coordinates. After the calculation, the server further verifies the rationality of the monitor deployment: it determines whether the calculated distance is within the preset effective monitoring coverage range of this type of monitor (e.g., the effective distance of a high-pressure pipe monitor is ≤5 meters), and confirms whether the perpendicular distance falls between the two endpoints of the corresponding pipeline segment (excluding the case where the monitor is mistakenly associated with other pipeline segments). It records the verification results for compliance, distance exceeding limits, and perpendicular distance deviation from the pipeline segment, and temporarily stores them along with the ID and the calculated data.

[0050] S230 retrieves the monitoring level of the gas pipe monitor corresponding to the network access application. Specifically, it involves: first, based on the gas pipe monitor ID parsed from S220, retrieving the monitor's initial monitoring level from the server's preset device attribute database (e.g., the default initial monitoring level for high-pressure pipe monitors is level 1, and for medium- and low-pressure pipe monitors it's level 2). Then, combining the distance value, perpendicular coordinates, and location verification results output by S220, the initial level is adjusted according to the scenario: if the location verification is compliant, the initial monitoring level remains unchanged; if the distance is within limits but close to the threshold (e.g., 4.5-5 meters for high-pressure pipe monitors), the monitoring frequency is increased based on the initial level (without changing the level itself), retaining the original tag association logic; if the location verification shows the distance exceeds limits or the perpendicular deviates from the pipe segment, the monitoring level is directly increased by one level (e.g., level 2 is upgraded to level 1), and it is marked as requiring on-site verification; if the perpendicular coordinates fall on other pipe segments, the corresponding pipe segment information is re-associated, and the monitoring level is adjusted according to the new pipe segment type to ensure accurate matching between the level and the actual monitored object, ultimately determining the monitor's final monitoring level.

[0051] S240 establishes a mapping relationship between the tags corresponding to the monitoring levels and the gas pipe monitor IDs. Specifically, based on the final monitoring level determined in S230, it automatically matches the corresponding monitoring tag (the first level corresponds to the high-pressure pipe monitoring tag, the second level to the medium- and low-pressure pipe monitoring tag, and the third level to the user access pipe monitoring tag). Using the gas pipe monitor ID parsed in S220 as the core index, a structured data association table is constructed. The final monitoring level, the matched monitoring tag, the spatial distance value calculated in S220 (retaining two decimal places), the perpendicular latitude and longitude coordinates, the location verification result, and the level correction description are sequentially filled in, forming a complete data chain of ID-level-tag-geographical parameters-verification result. This association table is then synchronized to a dedicated data table in the storage, an ID index is established to ensure rapid subsequent retrieval, and a data verification code is generated and bound to the association table content to prevent data tampering, thus completing the solidified storage of the mapping relationship.

[0052] Specifically, the tags include high-pressure pipe monitoring tags, medium- and low-pressure pipe monitoring tags, or user access pipe monitoring tags.

[0053] S250, return to the step of selecting a network access application, until all network access applications have been selected. Specifically, this includes: returning to step S210, selecting the next unprocessed gas pipeline monitor network access application in the order of submission time, and repeating the entire process from S210 to S240, including basic geographic data extraction and verification, ID parsing and algorithm solving, level correction and filing, and establishment of a complete mapping relationship. For invalid applications marked as needing correction in S210, a separate exception list is generated and fed back to the operation and maintenance management terminal, reminding the user to supplement the correct coordinate data and resubmit for processing. For monitors marked as requiring on-site verification in S230, the verification priority is marked in the mapping relationship and simultaneously pushed to the on-site operation and maintenance personnel's terminals. Until all network access applications are processed (including normal archiving and exception marking), the server updates the device network access status of the gas pipeline information monitoring network, confirming that each monitor has completed ID-tag mapping with geographic verification, providing data support for subsequent monitoring information retrieval and risk assessment.

[0054] Understandably, a gas pipe monitor ID can be obtained through the gas pipe monitor network access application. The high-pressure pipe monitoring tag, medium- and low-pressure pipe monitoring tag, or user access pipe monitoring tag of the gas pipe monitor are then mapped to the gas pipe monitor ID to establish a corresponding relationship.

[0055] Different management methods can be used for the data uploaded by the gas pipe monitor using different tags. The data uploaded by the gas pipe monitor is retrieved with the gas pipe monitor ID as the target, that is, the data uploaded by the gas pipe monitor corresponding to the gas pipe monitor ID is retrieved.

[0056] The gas pipeline information monitoring network comprehensively assesses the risks of each node in the gas pipeline based on the tags associated with the gas pipeline monitor IDs. This provides maintenance personnel with visualized data displays, helping them quickly identify potential safety hazards. The system receives data uploaded from each gas pipeline monitor in real time, monitors the operational status of the gas pipeline, promptly detects anomalies, and assists maintenance personnel in fault diagnosis and handling through its data analysis functions.

[0057] In one embodiment of this application, S600 includes: S610 calls up the ID of each gas pipe monitor that has a high-pressure pipe monitoring tag.

[0058] S620 retrieves pressure and flow data from the operating data corresponding to each gas pipe monitor ID.

[0059] S630 calls up the ID of each gas pipe monitor with a medium-low pressure pipe monitoring tag.

[0060] S640, obtain the ratio of pressure regulating cabinet to pressure regulating box valve well and gas environment concentration in the operating data corresponding to each gas pipe monitor ID.

[0061] S650 calls the ID of each gas pipe monitor that has a user access pipe monitoring tag.

[0062] S660 retrieves the flow and time data table and gas environment concentration from the operating data corresponding to each gas pipe monitor ID.

[0063] Understandably, appropriately increasing the gas transmission pressure can increase the gas flow rate within the pipeline, thereby increasing the gas transmission volume per unit time. Reasonable pressure increases help meet large-scale gas supply demands. However, when the pressure exceeds the pipeline's design limits, it can lead to pipe fatigue, weld cracking, or even bursting. Using gas pipe monitors to monitor high-pressure pipe pressure and flow data in real time can prevent electrochemical corrosion or stress corrosion cracking of the pipeline wall under high-pressure conditions, reduce pressure imbalances that cause unstable gas flow rates, alleviate turbulence or water hammer phenomena, and prevent pipe wall wear and thinning.

[0064] Medium and low-pressure pipelines are located in the middle section of the gas pipeline network. Pressure can be dynamically adjusted by pressure regulating stations to achieve precise matching of different areas and user needs. The proportion of pressure regulating cabinets is higher in the section of medium and low-pressure pipelines closer to high-pressure pipelines, while the proportion of pressure regulating box valve wells is higher in the section closer to user access pipes. Utilizing the ratio of pressure regulating cabinets to pressure regulating box valve wells, it is possible to determine whether the medium and low-pressure pipeline monitored by the gas pipeline monitor is a pipeline near or far from the gas source. The pressure regulating cabinets in the pressure regulating station can regulate the pressure of high-pressure gas, thereby greatly reducing the risk of gas leakage. Pressure regulating box valve wells include PE ball valve wells and steel ball valve wells. Due to frequent use, the probability of gas leakage from pressure regulating box valve wells is relatively high. Therefore, for gas pipeline monitors monitoring medium and low-pressure pipelines, extracting the ratio of pressure regulating cabinets to pressure regulating box valve wells and the gas environment concentration is crucial for monitoring medium and low-pressure pipelines. This helps to understand the overall layout, equipment distribution, and operating status of medium and low-pressure pipelines, providing strong data support for pipeline maintenance and management.

[0065] Gas pipe monitors that monitor user access pipes are exposed to the living environment for extended periods, which can easily lead to inaccurate monitoring data. By obtaining flow and time data tables, it is possible to determine whether the gas metering of the gas pipe monitor is accurate and whether there are any abnormal gas consumption situations. Combined with the gas concentration in the environment, it is possible to promptly determine the damage to the user access pipe.

[0066] In one embodiment of this application, S800 includes: S811 retrieves the pressure and flow data of each gas pipe monitor ID with a high-pressure pipe monitoring tag.

[0067] S812, Select a gas pipe monitor ID.

[0068] S813 receives temperature data from real-time weather data of the selected gas pipe monitor ID.

[0069] S814, based on pressure and flow data, determines whether the gas pipeline being monitored is under high pressure.

[0070] S815, if the target gas pipeline is not under high pressure, return to the step of selecting a gas pipeline monitor ID until all gas pipeline monitor IDs have been selected.

[0071] S816 If the target gas pipeline is under high pressure, determine whether the temperature data in the real-time weather data is greater than or equal to the target threshold.

[0072] S817 If the temperature data in the real-time weather data is greater than or equal to the target threshold, the gas pressure regulation channel is activated, and the first inspection tag is assigned to the monitored target gas pipeline.

[0073] S818: If the temperature data in the real-time weather data is less than the target threshold, a second inspection tag is assigned to the gas pipeline being monitored.

[0074] S819, return to the step of selecting a gas pipe monitor ID, until all gas pipe monitor IDs have been selected.

[0075] Understandably, when the target gas pipeline is not under high pressure, the high-pressure pipe has a smaller task of transporting gas and can maintain a safe internal pressure. When the target gas pipeline is under high pressure, the high-pressure pipe has a larger task of transporting gas, achieving high-flow-rate gas delivery through high internal pressure.

[0076] Under high pressure, when the temperature data in the real-time weather data is greater than or equal to the target threshold, that is, when the real-time weather temperature is greater than or equal to 30 degrees, it is necessary to use the gas pressure regulating channel to reduce the pressure of the high-pressure pipe. The pressure reduction operation belongs to the operation content of the first inspection tag, that is, manual inspection, and the pressure reduction operation is performed.

[0077] Under high pressure, when the temperature data in the real-time weather data is less than 30 degrees Celsius, manual inspection of the pipeline is required. This involves manually checking the actual condition of the pipeline, such as the outer wall of the pipeline. Manual inspection of high-pressure pipelines falls under the work content of the second inspection label.

[0078] In one embodiment of this application, S800 further includes: S821, call the ratio of the pressure regulating cabinet and the valve well of any gas pipe monitor with a medium and low pressure pipe monitoring tag.

[0079] S822, determine whether the ratio of the pressure regulating cabinet to the valve well of the pressure regulating box is greater than or equal to the target ratio threshold.

[0080] S823, if the ratio of the pressure regulating cabinet to the valve well of the pressure regulating box is greater than or equal to the target ratio threshold, then the target gas pipeline to be monitored is determined to be the pipeline near the gas source. Based on the gas environment concentration warning value of the pipeline near the gas source, a first leakage threshold is generated.

[0081] S824, if the ratio of the pressure regulating cabinet to the valve well of the pressure regulating box is less than the target ratio threshold, then the target gas pipeline to be monitored is determined to be the pipeline on the far gas source side. Based on the gas environment concentration warning value of the pipeline on the far gas source side, a second leakage threshold is generated.

[0082] S825 uses a minimum value function to select the minimum value between the first leakage threshold and the second leakage threshold as the warning threshold.

[0083] Understandably, each gas pipe monitor can monitor the medium and low-pressure pipes of a designated area. This area contains pressure regulating cabinets, pressure regulating boxes, and valve wells. By calling the data received by the gas pipe monitor ID with the medium and low-pressure pipe monitoring tag, it is determined whether the gas pipe monitor is receiving data from the pipes near or far from the gas source. Medium and low-pressure pipes near the gas source have a first leakage threshold based on the gas environment concentration warning value. Medium and low-pressure pipes far from the gas source have a second leakage threshold based on the gas environment concentration warning value.

[0084] Generally, medium- and low-pressure pipes closer to the gas source have more pressure regulating cabinets. Medium- and low-pressure pipes farther from the gas source have more pressure regulating box valve wells. By using the ratio of pressure regulating cabinets to pressure regulating box valve wells, it's possible to determine whether the gas pipe monitor is receiving signals from a pipe closer to or farther from the gas source. The target threshold for this ratio is generally 60%. A ratio greater than or equal to 60% indicates a medium- and low-pressure pipe closer to the gas source (i.e., a pipe closer to the gas source), while a ratio less than 60% indicates a medium- and low-pressure pipe farther from the gas source (i.e., a pipe farther from the gas source).

[0085] The minimum value function is used to select the lower of the first and second leakage thresholds as the warning threshold. Medium- and low-pressure pipes closer to the gas source generally receive high-pressure gas; once this high-pressure gas leaks, the gas concentration is high, so the first leakage threshold is generally higher than the second. Medium- and low-pressure pipes farther from the gas source are generally closer to the user's inlet pipe; the gas pressure in these pipes is lower and close to that in the user's inlet pipe, so the second leakage threshold can be used as the criterion for determining gas leakage in the user's inlet pipe.

[0086] In one embodiment of this application, S800 further includes: S831 retrieves the gas environment concentration of the target gas pipeline for each gas pipeline monitor ID with a medium-low pressure pipeline monitoring tag.

[0087] S832, Select a gas pipe monitor ID.

[0088] S833 receives the thunderstorm index from real-time weather data of the selected gas pipe monitor ID.

[0089] S834, determine whether the concentration of gas in the environment is greater than or equal to the warning threshold.

[0090] S835, if the gas concentration in the environment is less than the warning threshold, return to the step of selecting a gas pipe monitor ID until all gas pipe monitor IDs have been selected.

[0091] S836, if the concentration of gas in the environment is greater than the warning threshold, then is the thunderstorm index greater than or equal to the target index threshold?

[0092] S837: If the thunderstorm index is greater than or equal to the target index threshold, a third inspection tag will be assigned to the gas pipeline being monitored.

[0093] S838, if the thunderstorm index is less than the target index threshold, then the gas pipeline being monitored will be assigned a fourth inspection tag.

[0094] S839, return to the step of selecting a gas pipe monitor ID, until all gas pipe monitor IDs have been selected.

[0095] Understandably, gas leaks are possible in low- and medium-pressure pipelines due to low gas pressure. The areas most prone to leaks within these pipelines are pressure regulating cabinets and valve wells. When the gas concentration in the environment is below the warning threshold, no leaks are detected in the monitored low- and medium-pressure pipelines. However, if the gas concentration exceeds the warning threshold, a leak is likely in the pressure regulating cabinet or valve well. When the thunderstorm index is greater than or equal to the target index threshold (e.g., a level 2 thunderstorm index), manual shutdown of the low- and medium-pressure pipelines is required. This manual shutdown is the third inspection step.

[0096] It is worth mentioning that the thunderstorm index is a mathematical model built on physical quantities such as atmospheric stratification stability, water vapor conditions, and vertical motion. It is used to determine whether the conditions for thunderstorm formation are present in a specific area or time period. The Swiss New Thunderstorm Forecast Index is a thunderstorm index that determines whether thunderstorm weather will occur. When the threshold of the Swiss New Thunderstorm Forecast Index is 2700, thunderstorms are predicted. The level 2 thunderstorm index is the Swiss New Thunderstorm Forecast Index threshold of 2700.

[0097] When the concentration of natural gas in the environment exceeds the warning threshold, but there is no thunderstorm, the gas flow is often altered. This involves manually changing the gas's path in the pipeline to vacate potential pressure regulating cabinets or valve wells, thus preventing further gas leakage. Manually altering the gas flow path in the pipeline is part of the fourth inspection tag's work.

[0098] In one embodiment of this application, S800 further includes: S841 calls the flow and time data table of each gas pipe monitor ID with a user access pipe monitoring tag and monitors the gas environment concentration of the target gas pipeline.

[0099] S842, Select a gas pipe monitor ID.

[0100] S843, retrieves the measured gas usage recorded by the gas pipe monitor ID.

[0101] S844, based on flow and time data tables, obtains statistical data on gas usage.

[0102] S845, determine whether the statistical gas usage matches the measured gas usage.

[0103] S846 If the statistical gas usage does not match the measured gas usage, a fifth inspection tag shall be assigned to the gas pipeline of the monitoring target.

[0104] S847, if the statistical gas usage matches the measured gas usage, then determine whether the gas environment concentration of the monitored target gas pipeline is greater than or equal to the second leakage threshold.

[0105] S848, if the gas environment concentration of the monitored target gas pipeline is greater than or equal to the second leakage threshold, then the monitored target gas pipeline is assigned a sixth inspection tag.

[0106] S849, if the gas environment concentration of the monitored target gas pipeline is less than the second leakage threshold, then the monitored target gas pipeline is assigned a seventh inspection tag.

[0107] S849a, return to the step of selecting a gas pipe monitor ID, until all gas pipe monitor IDs have been selected.

[0108] Understandably, the flow and time data table can be used to obtain the statistical gas usage, and the gas pipe monitor will also measure the gas usage. These two sets of data come from the flow sensor and flow metering device of the gas pipe monitor. When the statistical gas usage does not match the measured gas usage, it means that the flow sensor and flow metering device of the gas pipe monitor need to be repaired. Repairing the flow sensor and flow metering device of the gas pipe monitor falls under the work content of the fifth inspection tag.

[0109] When the concentration of gas in the monitored gas pipeline is greater than or equal to the second leakage threshold, it indicates a potential risk of leakage in the user's connection pipe, requiring immediate investigation of possible fault points. Immediate investigation of potential fault points falls under the responsibilities of the sixth inspection tag.

[0110] When the gas concentration in the target gas pipeline is less than the second leakage threshold, a routine periodic inspection is performed. Performing a routine periodic inspection is part of the work content of the seventh inspection label.

[0111] like Figure 2 As shown, the gas pipeline monitoring system provided by the present invention includes a server 100, a memory 200, and a gas pipeline monitor 300.

[0112] The server 100 is used to execute a gas pipeline monitoring method.

[0113] The memory 200 is communicatively connected to the server 100.

[0114] The gas pipe monitor 300 is communicatively connected to the server 100.

[0115] This application relates to a gas pipeline monitoring system. The server 100 receives network access applications from each gas pipeline monitor 300 to form a gas pipeline information monitoring network. The system uses real-time information stored in the memory 200 to comprehensively assess the risks of each node in the gas pipeline, provides visualized data display, quickly identifies potential safety hazards, and retrieves monitoring information of each gas pipeline monitor ID in the gas pipeline information monitoring network to fully understand the overall layout, equipment distribution, and operating status of the gas pipeline, monitor the operating status of the gas pipeline in real time, and promptly detect abnormalities.
