Accidents caused by third-party construction are a major cause of oil and gas pipeline accidents in my country. Current technology involves installing vibration sensors in communication fiber optic cables laid in the same trench as the pipeline to detect vibration signals and thus monitor pipeline safety. However, traditional technology cannot systematically manage pipeline safety, relying on inspection personnel to patrol the fiber optic cables to identify risk locations. This is labor-intensive and lacks timely warnings for inspection personnel. Summary of the Invention

[0010] In one embodiment of this application, the alarm information includes historical alarm information and current alarm information. The historical alarm information includes historical vibration source location, historical vibration generation time, and historical alarm ID. The current alarm information includes current vibration source location, current vibration generation time, and current alarm ID. Merging alarm information according to preset alarm rules to determine target alarm information includes: if historical alarm information exists within a preset distance from the current vibration source location, replacing the current alarm ID with the historical alarm ID and determining the replaced current alarm information as the target alarm information; if historical alarm information exists within a first preset time range before the current vibration generation time, replacing the current alarm ID with the historical alarm ID and determining the replaced current alarm information as the target alarm information.

[0011] In one embodiment of this application, the control management center module filters target alarm information according to preset rules, including: after receiving target alarm information, the management center module determines the target vibration generation time and target vibration source location of the target alarm information; determines whether the target vibration generation time and target vibration source location are the vibration generation time and vibration source location corresponding to a deterministic event, wherein the deterministic event includes at least one of a fixed vibration environment, a seasonal construction event, and a temporary construction event; after determining that the target vibration generation time and target vibration source location are the vibration generation time and vibration source location corresponding to a deterministic event, the control management center module filters the target alarm signal.

[0012] In one embodiment of this application, analyzing the filtered target alarm information to determine the risk location of an oil and gas pipeline with intrusion risk includes: acquiring multiple target alarm information within a second preset time range; determining the target vibration source location corresponding to each target alarm information; and determining the oil and gas pipeline location closest to the vibration source location as the risk location of the oil and gas pipeline with intrusion risk.

[0029] like Figure 1 As shown, a flowchart illustrating an intrusion warning method for oil and gas pipelines according to this application is presented. Figure 1 As shown, an intrusion early warning method for oil and gas pipelines includes the following steps:

[0030] Step 101: Collect vibration signals generated by the vibration source through the fiber optic sensing device module, and analyze the vibration signals to determine the location of the vibration source;

[0031] Step 102: Upload the vibration source location to the monitoring center module, and control the monitoring center module to generate corresponding target alarm information based on the vibration source location, and send the target alarm information to the management center module;

[0032] Step 103: The control and management center module filters the target alarm information according to preset rules and analyzes the filtered target alarm information to determine the risk location where there is an intrusion risk in the oil and gas pipeline.

[0033] Step 104: The control and management center module issues early warning prompts based on the risk location.

[0034] like Figure 2The diagram illustrates the structural structure of an intrusion warning system 200, which includes a fiber optic sensing module 201, a monitoring center module 202, and a management center module 203. The processor can collect vibration signals generated by a vibration source through the fiber optic sensing module 201 and analyze the vibration signals to determine the location of the vibration source. After determining the location of the vibration source through the collected vibration signals, the processor can control the fiber optic sensing module 201 to upload the vibration source location to the monitoring center module 202. Upon receiving the vibration source location uploaded by the fiber optic sensing module 201, the processor can control the monitoring center module 202 to generate corresponding target alarm information based on the vibration source location and send the generated target alarm information to the management center module 202. Upon receiving the target alarm information, the processor can control the management center module 202 to filter the target alarm information according to preset rules and analyze the filtered target alarm information to determine the risk location where there is an intrusion risk in the game pipeline. After the management center module 202 determines the risk location, the processor can control the management center module 202 to issue corresponding early warning prompts based on the risk location.

[0035] In one embodiment, the intrusion warning system further includes a fiber optic vibration sensor. The fiber optic sensor is mounted on an optical fiber and collects vibration signals through the fiber optic vibration sensing device module. Analyzing the vibration signals to determine the vibration source location includes: the fiber optic sensing device module acquiring the vibration signals detected by the fiber optic vibration sensor; performing noise reduction processing on the vibration data of the vibration signal using high-pass filtering, mean filtering, and wavelet transform to reduce noise data in the vibration data; performing data enhancement on vibration data below a preset frequency range; mapping each vibration intensity value to a preset color range according to a preset mapping rule for the noise-reduced and enhanced vibration data to generate a two-dimensional waterfall plot corresponding to the vibration data; and determining the vibration source location based on the two-dimensional waterfall plot.

[0036] The intrusion warning system also includes fiber optic vibration sensors mounted on optical fibers. The fiber optic sensing module can detect vibration signals through pipeline vibration sensors. After acquiring the vibration signals detected by the fiber optic vibration sensors, the module performs noise reduction processing on the vibration data using high-pass filtering, mean filtering, and wavelet transform to reduce noise data, such as persistent background noise. The processor can also enhance vibration data below a preset frequency range. The processor can identify the frequency of the vibration signal and enhance vibration data below the preset frequency range to improve the detection rate of weak signal intrusions. Because optical power attenuates during fiber transmission, inconsistencies in intensity values ​​between different segments may occur. The processor can normalize the vibration intensity in the vibration data. The processor can also organize the data, generating a two-dimensional array according to preset row and column standards and saving it using the .npy standard format.

[0037] The processor can map each vibration intensity value to a preset color range according to preset mapping rules after noise reduction, enhancement, and intensity normalization of the data, generate a two-dimensional waterfall plot corresponding to the vibration data, and determine the vibration source location based on the two-dimensional waterfall plot.

[0038] In one embodiment, the control and monitoring center module generates corresponding target alarm information based on the vibration source location by: acquiring the vibration frequency of the vibration signal generated at the vibration source location; determining the vibration source location corresponding to the vibration frequency greater than a preset vibration frequency range as the vibration source location to be alarmed; generating corresponding alarm information based on the two-dimensional waterfall plot corresponding to the vibration source location to be alarmed, wherein the alarm information includes at least one of the vibration source location, vibration frequency, vibration generation time, and information ID; and merging the alarm information according to preset alarm rules to determine the target alarm information.

[0039] The monitoring center module can acquire the vibration frequency of the vibration signal generated at the vibration source location, detect the vibration frequency, and determine the vibration source location corresponding to the vibration frequency greater than a preset vibration frequency range as the vibration source location to be alarmed. The processor can acquire a two-dimensional waterfall plot corresponding to the vibration source location to be alarmed and generate corresponding alarm information based on the two-dimensional waterfall plot. For example, the processor can use image recognition technology to identify preset features in the image to determine the alarm information. The alarm information includes at least one of the following: vibration source location, vibration frequency, vibration generation time, and information ID. For target alarm information, the processor can merge alarm information according to preset alarm rules to determine the target alarm information.

[0040] In one embodiment, the alarm information includes historical alarm information and current alarm information. The historical alarm information includes the historical vibration source location, the historical vibration occurrence time, and the historical alarm ID. The current alarm information includes the current vibration source location, the current vibration occurrence time, and the current alarm ID. Merging alarm information according to a preset alarm rule to determine the target alarm information includes: if it is determined that there is historical alarm information within a preset distance from the current vibration source location, replacing the current alarm ID with the historical alarm ID and determining the replaced current alarm information as the target alarm information; if it is determined that there is historical alarm information within a first preset time range before the current vibration occurrence time, replacing the current alarm ID with the historical alarm ID and determining the replaced current alarm information as the target alarm information.

[0041] After generating corresponding alarm information based on the 2D waterfall plot corresponding to the alarm source location, the alarm information can be merged according to preset alarm rules. Upon detecting a current alarm, the current source location can be determined. If historical alarm information exists within a preset distance from the current source location (meaning alarm information already exists within the preset distance range of the source location displayed in the newly added alarm information), the processor can replace the current alarm ID in the current alarm information with the historical alarm ID from the historical alarm information, and then designate the current alarm information with the replaced alarm ID as the target alarm. In other words, alarm information within the preset distance range is merged using the same alarm ID, but parameters such as the source location need to be refreshed.

[0042] Similarly, after detecting the current alarm information, the current vibration occurrence time can be determined based on the current alarm information. If there is historical alarm information within a first preset time range before the current vibration occurrence time is determined, the processor can replace the current alarm ID in the current alarm information with the historical alarm ID in the historical alarm information, and determine the current alarm information after the alarm ID replacement as the target alarm information.

[0043] In one embodiment, the control management center module filters target alarm information according to preset rules, including: after receiving target alarm information, the management center module determines the target vibration generation time and target vibration source location of the target alarm information; determines whether the target vibration generation time and target vibration source location are the vibration generation time and vibration source location corresponding to a deterministic event, wherein the deterministic event includes at least one of a fixed vibration environment, a seasonal construction event, and a temporary construction event; after determining that the target vibration generation time and target vibration source location are the vibration generation time and vibration source location corresponding to a deterministic event, the control management center module filters the target alarm signal.

[0044] After receiving target alarm information, the processor can control the management center module to filter the target alarm information according to preset rules. The management center module can store the vibration generation time and source location corresponding to deterministic events. Deterministic events can include fixed vibration environments (e.g., factories, long-term construction projects), seasonal construction events, and temporary construction events. The control management center module can determine the target vibration generation time and target source location of the target alarm information, and compare the target vibration generation time and target source location in the target alarm information with the vibration generation time and source location corresponding to the deterministic event. If the target vibration generation time and target source location match the vibration generation time and source location corresponding to the deterministic event, the processor can control the management center module to filter the target alarm information. The management center module can also filter periodic vibration information occurring at specific locations based on geographical location, land attributes, and other information.

[0045] In one embodiment, analyzing the filtered target alarm information to determine the risk location of an oil and gas pipeline with intrusion risk includes: acquiring multiple target alarm information within a second preset time range; determining the target vibration source location corresponding to each target alarm information; and determining the oil and gas pipeline location closest to the vibration source location as the risk location of the oil and gas pipeline with intrusion risk.

[0046] After filtering the target alarm information, the management center module can obtain multiple target alarm information within a second preset time range, and determine the target vibration source location corresponding to each target alarm information based on the target alarm information. The location of the oil and gas pipeline closest to the vibration source location is identified as the risk location where the oil and gas pipeline has an intrusion risk.

[0047] In one embodiment, after the control management center module issues an early warning based on the risk location, the control management center module obtains the information feedback input by the user in response to the early warning; generates user filtering rules for the target alarm information based on the information feedback, and enables the user filtering rules when filtering the target alarm information in the future.

[0048] The processor can control the management center module to issue early warnings to users based on risk locations. For example, the management control center module can display alarm information on the map interface to prompt patrol personnel to confirm the location. Patrol personnel can confirm the location on-site based on the alarm information and provide feedback to the management center module regarding the early warning. After receiving the user's feedback, the management center module can generate user filtering rules for the target alarm information and enable these rules when filtering target alarm information subsequently. For example, assuming the target alarm information displays the location of vibration source A, after a user goes to location A to confirm that the target alarm information corresponding to location A is a harmless alarm, the user can set the alarm information at location A to be blocked. The management center module can then filter the alarm information at location A when filtering target alarm information subsequently.

[0049] In one embodiment, a processor is provided, configured to perform any of the above-described intrusion warning methods for oil and gas pipelines.

[0050] In one embodiment, such as Figure 2 The diagram illustrates the device structure of an intrusion warning system 200. The intrusion warning system 200 includes a fiber optic sensing device module 201 for collecting vibration signals and analyzing the vibration signals to determine the location of the vibration source; a monitoring center module 202 for determining the corresponding target alarm information based on the vibration source location; a management center module 203 for filtering the target alarm information according to preset rules, analyzing the filtered target alarm information to determine the risk location of the oil and gas pipeline where intrusion is possible, and providing early warning prompts for the risk location; and a processor 204.

[0051] In one embodiment, such as Figure 3As shown, the system includes a fiber optic sensing device module 301. This module can acquire vibration data, process, reduce noise, enhance, and compress the acquired vibration data, and then store the compressed data. The processed and noise-enhanced data can be used to determine the vibration source location using a waterfall plot algorithm and then reported. The fiber optic sensing device module 301 can report the vibration source location to the monitoring center module 302. After receiving the data related to the vibration source location, the monitoring center module 302 can generate alarm information through the waterfall chart algorithm and merge the generated alarm information to obtain the target alarm information. The monitoring center module 302 can display the target alarm information and push it to the management center module 303. After receiving the target alarm information, the management center module 302 can make a comprehensive judgment on the target alarm information, that is, filter the target alarm information. The filtered target alarm information is statistically analyzed and sent to the data application. The data application sends it to the corresponding patrol APP to provide early warning to the patrol personnel. The patrol personnel can input feedback on the early warning through the patrol APP. The patrol APP can provide feedback on the results and determine the feedback of the patrol personnel as new filtering rules for filtering the target alarm information during the comprehensive judgment.

[0052] Through the above technical solution, by setting up an intrusion early warning system and enabling interaction between different modules, the fiber optic sensing module collects data and determines the location of the vibration source based on the data. Accurate location of the vibration source through vibration data reduces labor costs. The vibration source location is then sent to the monitoring center module, which generates an alarm based on the location and sends it to the management center module. The management center module identifies the risk location based on the alarm and issues a risk location warning. It also interacts with inspection personnel, pushing risk locations to them and obtaining timely feedback, thus improving the processing of alarm information. The intrusion early warning system enables systematic management of oil and gas pipelines, facilitating accurate location of risk areas by inspection personnel and enabling timely investigation of these areas.
