Description

Technical Field

[0001] The present invention relates to the technical field of gas monitoring, and in particular to an information-based gas leakage monitoring system. Background Art

[0002] Gas leak monitoring refers to the real-time detection and analysis of the presence, concentration and changes of specific gases in the environment through various technical means and equipment to detect potential gas leaks and ensure the safety of personnel, environmental health and the normal operation of industrial facilities. Many gases used or produced in industrial production, such as natural gas, coal gas, ammonia, etc., are flammable, explosive or toxic and harmful. Timely detection of leaks can avoid major safety accidents such as explosions, fires, and poisoning.

[0003] When using common gas leakage monitoring systems, it is difficult to quickly detect possible gas problems in complex locations, which can lead to the continued development of problems and serious consequences. At the same time, it is impossible to accurately assess the loss of gas during pipeline transportation, which can easily lead to misjudgment. For this reason, we propose an information-based gas leakage monitoring system. Summary of the invention

[0004] The purpose of the present invention is to provide an information-based gas leakage monitoring system.

[0005] To solve the problems raised in the above background technology, the present invention provides the following technical solutions: an information-based gas leakage monitoring system, comprising a layout module, a data monitoring module, an abnormality root module, an abnormality matching module and a location analysis module;

[0006] The layout module obtains the type information of the monitored gas, selects the gas monitor according to the type information of the monitored gas, analyzes the pipeline turning points and pipeline diversion points during the pipeline transportation of the gas, obtains the installation points, and installs the gas monitors before and after the corresponding installation points respectively;

[0007] The data monitoring module collects the gas flow information detected by the gas monitor, and then groups the gas monitor in front of the current installation point with the gas monitor in the rear of the previous installation point to obtain a loss group, and groups the gas monitors close to each other in different loss groups into a monitoring group, and then calculates the transmission and reception index between the gas flow information before and after the loss group and the detection group;

[0008] The abnormal root cause module analyzes the connection devices corresponding to different installation points, determines the cause of gas leakage at the installation point, and analyzes the gas leakage rate range caused by different reasons, establishes a retrieval unit, and then records the cause of gas leakage and gas leakage rate range in the retrieval unit;

[0009] The abnormal matching module extracts the transmission and reception indexes, analyzes the gas leakage information, and then matches the gas leakage information in the retrieval unit to obtain the matching results and judge whether the different transmission and reception indexes are abnormal;

[0010] When the transceiver index is abnormal, it will be transmitted to the location analysis module and the cause of the gas leakage will be extracted;

[0011] When the transmission and reception index is not abnormal, the transmission and reception index will be deleted;

[0012] The location analysis module extracts the transmission and reception index and analyzes the loss group and monitoring group represented by the transmission and reception index, thereby analyzing the location where the gas leakage occurs.

[0013] As a further solution of the present invention: it also includes an early warning verification module;

[0014] The early warning verification module includes an alarm device and a verification unit, wherein the alarm device is installed at different installation points. After analyzing the location of the gas leakage, the alarm devices on both sides of the gas leakage location will be controlled to make the alarm devices perform alarm processing. When the staff completes the detection of the gas leakage location, the detection results will be entered into the verification unit, and the cause of the gas leakage will be verified based on the detection results.

[0015] As a further solution of the present invention, when calculating the transmission and reception index, the data monitoring module will establish a primary unit and a continuation unit, and use the primary unit and the continuation unit to calculate the loss information of the gas during transportation. When the loss information is obtained for the first time, the primary unit will be used to record the cause of the transportation loss during the gas transportation, and the loss information will be calculated through the primary unit. Let the cause of the transportation loss during the gas transportation be S Y , let the transportation loss caused by different reasons be Y H , where Y H is a range value, let the number of reasons that lead to transportation loss during gas transportation be S, let the loss information of the initial unit analysis be S 损耗 ;

[0016]

[0017] The loss information of the initial unit analysis is calculated according to the above formula, and the two gas flow information monitored by the gas monitor in the loss group and the monitoring group are extracted at the same time, and the difference between the two gas flow information is calculated to obtain the transportation loss information and the actual loss information.

[0018] As a further solution of the present invention: when establishing the initial unit and the continuation unit, the data monitoring module will synchronously establish a conversion threshold for the initial unit and the continuation unit, and the loss information calculated using the initial unit and the actual loss information will be synchronously recorded in the continuation unit. When the number of loss information calculated using the initial unit is higher than the conversion threshold, the continuation unit will overwrite the initial unit, and then the continuation unit will extract the actual loss information, sort the actual loss information, and obtain a sorting table.

[0019] As a further solution of the present invention: after obtaining the sorting table, the data monitoring module extracts the first actual loss information and the last actual loss information in the sorting table, and calculates their loss index, assuming that the first actual loss information is D1 and the last actual loss information is Z H , let the loss index be S 指数 ;

[0020]

[0021] The loss index is calculated according to the above formula, and the gas flow information monitored by the first gas monitor in the loss group is extracted at the same time.

[0022] As a further solution of the present invention: after obtaining the gas flow information monitored by the first gas monitor, the data monitoring module will calculate the range of the gas flow information monitored by the second gas monitor through the loss index. Suppose the gas flow information monitored by the first gas monitor is D Y , assuming that the gas flow information monitored by the second gas monitor is D E ;

[0023] When D Y -D Y ·S 指数 ≤D E ≤D Y When , the difference between the two gas flow information in the loss group is judged to be normal loss;

[0024] When D E <D Y -D Y ·S 指数 When the difference between the two gas flow information in the loss group is determined to be abnormal loss, an abnormal loss signal is generated.

[0025] As a further solution of the present invention: after receiving the abnormal loss signal, the abnormal matching module analyzes the gas leakage speed corresponding to the gas leakage information to obtain the retrieval leakage speed, assuming that the retrieval leakage speed is J 泄漏 , assuming that the range of different gas leakage rates in the retrieval unit is X 范围 , let the matching result be J 结果 ;

[0026] J 结果 =J 泄漏 ∈X 范围

[0027] According to the above formula, the matching result is calculated. When the transmission and reception index is abnormal, When the transmission and reception index is normal, it is judged that the transmission and reception index is not abnormal.

[0028] As a further solution of the present invention: before analyzing the location of the gas leakage, the location analysis module will set unique numbers for different loss groups and monitoring groups, and convert the distance between two installation points in different loss groups and monitoring groups into labels marked on different unique numbers.

[0029] As a further solution of the present invention: after verifying the cause of the gas leakage according to the detection results, the early warning verification module will simultaneously analyze whether the cause of the gas leakage is consistent with the detection results. When it is consistent, the detection result will be deleted. When it is not consistent, the detection result and the gas leakage information will be transmitted to the retrieval unit of the abnormal root cause module.

[0030] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. The present invention can comprehensively and timely monitor the state of gas at key nodes through the layout module, which helps to timely discover possible problems of gas in these complex parts. The data monitoring module can deeply analyze the flow changes of gas between different positions and accurately evaluate the loss of gas during pipeline transportation. The abnormal root module provides a detailed reference basis for subsequent rapid matching and positioning of abnormal situations. The abnormal matching module can quickly and accurately identify abnormal situations in the gas transportation process, reducing the impact caused by gas leakage;

[0032] 2. The present invention records the causes of gas transportation loss through the data monitoring module, can accurately grasp the loss situation in the gas transportation process, provide an accurate data basis for subsequent analysis, effectively manage loss information, ensure that the system uses the latest and most representative data for analysis, improve the accuracy and timeliness of the system's judgment on the gas transportation status, and provide a clear reference standard for judging whether the difference in gas flow information is normal, which helps to more accurately discover potential anomalies;

[0043] The abnormal matching module extracts the transmission and reception indexes, analyzes the gas leakage information, and then matches the gas leakage information in the retrieval unit to obtain the matching results and judge whether the different transmission and reception indexes are abnormal;

After analyzing the location of the gas leak, the alarm devices on both sides of the gas leak location will be controlled to make the alarm devices perform alarm processing. When the staff completes the detection of the gas leak location, the detection results will be entered into the verification unit, and the cause of the gas leak will be verified based on the detection results;

[0051] Furthermore, the layout module can comprehensively and timely monitor the status of gas at key nodes, which helps to promptly discover possible problems with gas in these complex locations. The data monitoring module can deeply analyze the flow changes of gas between different locations and accurately evaluate the loss of gas during pipeline transportation. The abnormal root cause module can provide detailed reference basis for subsequent rapid matching and positioning of abnormal situations. The abnormal matching module can quickly and accurately identify abnormal situations in the gas transportation process and reduce the impact caused by gas leakage. At the same time, the early warning verification module can accurately obtain the abnormal location.

[0052] Embodiment 2:

[0053] Based on the first embodiment, as shown in the accompanying drawings of the specification Figure 1 As shown, when calculating the transmission and reception index, the data monitoring module will establish the initial unit and the continuation unit, and use the initial unit and the continuation unit to calculate the loss information of the gas during transportation. When the loss information is obtained for the first time, the initial unit will be used to record the cause of the transportation loss during gas transportation, and the loss information will be calculated through the initial unit. Suppose the cause of the transportation loss during gas transportation is S Y , let the transportation loss caused by different reasons be Y H , where Y H is a range value, let the number of reasons that lead to transportation loss during gas transportation be S, let the loss information of the initial unit analysis be S 损耗 ;

[0054]

[0056] Analyze the changing patterns of pipeline friction loss at different times of the day to determine whether there are other potential influencing factors, and provide a basis for the dynamic evaluation of the system operation status. At the same time, the actual loss information will be compared and analyzed with the historical data of the same period. If it is found that there is a large difference between the current actual loss and the historical data, the possible reasons for the difference will be automatically traced;

[0057] When establishing the initial unit and the continuation unit, the data monitoring module will synchronously establish a conversion threshold for the initial unit and the continuation unit. At the same time, the loss information calculated by the initial unit and the actual loss information will be synchronously recorded in the continuation unit. When the number of loss information calculated by the initial unit is higher than the conversion threshold, the continuation unit will overwrite the initial unit, and then the continuation unit will extract the actual loss information, sort the actual loss information, and obtain a sorting table;

[0058] After obtaining the sorting table, the data monitoring module will extract the first actual loss information and the last actual loss information in the sorting table and calculate their loss index. Let the first actual loss information be D1 and the last actual loss information be Z. H , let the loss index be S 指数 ;

[0059]

When the number of loss information calculated by the initial unit is higher than the conversion threshold, the continuation unit will cover the initial unit, and then the continuation unit will extract the actual loss information and calculate its loss index, and then extract the gas flow information monitored by the first gas monitor in the loss group;

[0062] Furthermore, by recording the causes of gas transportation losses through the data monitoring module, the loss situation in the gas transportation process can be accurately grasped, providing an accurate data basis for subsequent analysis, effectively managing loss information, ensuring that the system uses the latest and most representative data for analysis, and improving the accuracy and timeliness of the system's judgment on the gas transportation status. It provides a clear reference standard for judging whether the difference in gas flow information is normal, which helps to more accurately detect potential anomalies.

[0063] Embodiment three:

[0064] Based on the second embodiment, as shown in the accompanying drawings of the specification Figure 1 As shown in FIG. 1 , after obtaining the gas flow information monitored by the first gas monitor, the data monitoring module will calculate the range of the gas flow information monitored by the second gas monitor through the loss index. Suppose the gas flow information monitored by the first gas monitor is D Y , assuming that the gas flow information monitored by the second gas monitor is D E ;

[0065] When D Y -D Y ·S 指数 ≤D E ≤D YWhen , the difference between the two gas flow information in the loss group is judged to be normal loss;

[0066] When D E <D Y -D Y ·S 指数 When the difference between the two gas flow information in the loss group is determined to be abnormal loss, an abnormal loss signal is generated;

[0069] According to the above formula, the matching result is calculated. When the transmission and reception index is abnormal, When the transmission and reception index is normal,

[0070] Different response measures are taken according to the judgment results. For low-risk uncertain situations, the monitoring frequency will be increased to pay close attention to changes in gas transmission status. For medium-risk situations, in addition to increasing the monitoring frequency, the operation and maintenance personnel will be notified to prepare in advance. For high-risk situations, conservative safety measures will be taken immediately, such as reducing gas transmission pressure, expanding the evacuation range, etc. At the same time, professional personnel will be organized to conduct in-depth investigation and processing to ensure system safety;

[0071] Before analyzing the location of the gas leak, the location analysis module sets unique numbers for different loss groups and monitoring groups, and converts the distance between two installation points in different loss groups and monitoring groups into labels marked on different unique numbers;

[0072] After verifying the cause of the gas leakage according to the detection results, the early warning verification module will simultaneously analyze whether the cause of the gas leakage is consistent with the detection results. If it is consistent, the detection result will be deleted. If it is not consistent, the detection result and gas leakage information will be transmitted to the retrieval unit of the abnormal root cause module;

[0073] Specific workflow: Calculate the range of gas flow information monitored by the second gas monitor through the loss index, calculate the matching result, and then When the transmission and reception index is abnormal, When the transmission and reception index is normal, unique labels are set for different loss groups and monitoring groups, and the distances between two installation points in different loss groups and monitoring groups are converted into labels and marked on different unique labels. The cause of gas leakage is analyzed to see if it is consistent with the detection result. If it is consistent, the detection result will be deleted. If it is not consistent, the detection result and gas leakage information will be transmitted to the retrieval unit of the abnormal root cause module.

[0074] Furthermore, the data monitoring module can promptly detect abnormal changes in gas flow and effectively prevent serious problems such as gas leakage. The abnormal matching module can quickly identify abnormal conditions in the gas transportation process, prevent further expansion of gas leakage, and reduce losses caused by gas leakage. The location analysis module can quickly obtain the location of gas leakage, greatly improving the efficiency of maintenance and processing, and reducing the time and cost of troubleshooting.
