Detailed Embodiments

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0040] Existing oil and gas pipelines have problems such as low positioning accuracy and low efficiency in detecting oil leakage, and cannot accurately locate the leakage point in time, thus causing immeasurable losses. Most of the existing detections of natural gas pipeline leakage rely on manual hand-held detection instruments to gradually check along the pipeline, with low efficiency and being prone to danger when encountering leakage.

[0041] To solve the above defects of the existing technologies, the present invention uses distributed optical fiber sensing to conduct real-time monitoring of oil pipelines, and uses drones to replace manual labor for regular inspections and emergency inspections. This can not only improve the inspection efficiency and effect, but also improve the automation degree of inspections, and ensure the personal safety of inspection personnel. It is the direction that future pipeline inspections should focus on developing.

[0042] Figure 1 shows a structural block diagram of a drone inspection system for oil and gas pipeline leakage according to an embodiment of the present invention.

[0043] As Figure 1 shown, the oil and gas pipeline leakage system includes a drone 100. Among them, the drone 100 is equipped with a precise cruising system 101, a detection system 102, and a data processing system 105.

[0044] In one embodiment, the precise cruise system 101 is used to support the drone 100 to cruise along the laying path of the oil and gas pipeline. Specifically, the precise cruise system 101 utilizes the positioning function of the drone 100 to respond to the positioning blocks installed on the oil and gas pipeline, ensuring that the flight trajectory of the drone 100 cruises along the oil and gas pipeline.

[0045] Furthermore, positioning blocks are arranged on the oil and gas pipeline, which can wirelessly respond to the precise cruise system 101, enabling the precise cruise system 101 to provide a precise path for the drone to cruise. In one embodiment, a positioning block is arranged every 100 m on the oil and gas pipeline.

[0046] It should be noted that the wireless response method between the precise cruise system 101 and the positioning blocks and the layout interval of the positioning blocks are selected according to the actual situation, and the present invention does not limit this.

[0047] The precise cruise system 101 provided by the present invention can ensure that the drone 100 cruises along the laying path of the oil and gas pipeline, and can reduce the unnecessary along - the - way loss of the drone 100.

[0048] In one embodiment, the detection system 102 is used to detect the leakage situation of the oil and gas pipeline to obtain detection data, where the leakage situation includes natural gas leakage and oil leakage.

[0049] As Figure 1 shown, the detection system 102 includes: a laser probe detection module 103, which is used to detect the natural gas leakage situation of the oil and gas pipeline. Specifically, the laser probe detection module 103 includes: a laser probe and a laser receiver. Among them, the laser probe is used to emit laser during the cruise of the drone 100, and the laser receiver is used to receive the laser that returns through air propagation and generate a laser spectrum as detection data.

[0050] As Figure 1 shown, the detection system 102 includes: a photosensitive sensor detection module 104, which is used to detect the oil leakage situation of the oil and gas pipeline. Specifically, the photosensitive sensor detection module 104 includes: a photosensitive sensor, which is used to receive the infrared rays of the oil and gas pipeline as detection data.

[0051] In one embodiment, the oil and gas pipeline leakage system further includes: a laid optical fiber, which is laid along the oil and gas pipeline. Infrared rays are used for propagation inside the optical fiber, and a layer of rubber that can expand when encountering oil is provided outside. The rubber can transmit infrared rays.

[0052] Specifically, the optical fiber is laid along with the oil and gas pipeline, and infrared rays are transmitted inside the optical fiber. Further, there is a layer of rubber outside the laid optical fiber that can expand when encountering oil. This rubber can transmit infrared rays. When an oil leak occurs in the oil and gas pipeline, the expanded rubber squeezes the optical fiber inside, causing partial bending and changing the refractive index. At this time, some infrared rays inside the optical fiber cannot undergo total internal reflection and thus refract. At this time, the photosensitive sensor can receive the infrared rays refracted from the optical fiber.

[0053] The detection system 102 provided by the present invention can detect the leakage situation of the oil and gas pipeline, including a laser probe detection module 103 and a photosensitive sensing detection module 104. The laser probe detection module 103 can detect the leaked natural gas, and the photosensitive sensing detection module 104 can detect the oil leakage situation. The present invention uses a laser probe to perform spectral analysis on the leaked natural gas, with high detection efficiency. It can not only detect the leakage of natural gas but also analyze the diffusion range of natural gas, be able to promptly feedback the danger situation, and save time. The present invention uses optical fiber sensing to detect oil leakage, with high accuracy and a simple structure.

[0054] In one embodiment, the data processing system 105 is used to generate an inspection result based on the detection data. Specifically, the data processing system 105 is used to analyze the spectrum transmitted back by the laser probe detecting the gas, and collect the infrared light emitted from the optical fiber, and at the same time issue an alarm.

[0055] In one embodiment, the data processing system 105 includes: a natural gas leakage identification module, which is used to analyze the laser spectrum to detect whether there is a natural gas leakage, and then issue a natural gas leakage alarm as the inspection result.

[0056] When the data processing system 105 issues a natural gas leakage alarm, the flight altitude of the unmanned aerial vehicle 100 is increased and it hovers for shooting, which can detect the area where the natural gas has leaked in real time, and at the same time take a geographical image near the leakage point.

[0057] The data processing system 105 provided by the present invention is equipped with a machine automatic recognition function, which can analyze the laser spectrum, detect whether there is a natural gas leakage, and then trigger an alarm. After issuing the alarm, the data processing system 105 will issue an instruction to the unmanned aerial vehicle 100 to increase the flight altitude of the unmanned aerial vehicle 100 to hover, expand the monitoring range, and at the same time take on-site photos.

[0058] In one embodiment, the data processing system 105 includes: an oil leakage identification module, which is used to issue an oil leakage alarm as the inspection result when the photosensitive sensing detection module 104 receives the infrared rays of the oil and gas pipeline.

[0059] When the data processing system 105 issues an oil leakage alarm, the flight altitude of the drone 100 is increased and it hovers for shooting, which can detect the area where the oil has leaked in real time and simultaneously take geographical images near the leakage point.

[0060] The data processing system 105 provided by the present invention is equipped with a machine automatic recognition function, which can issue an alarm according to the infrared rays received by the photosensitive sensor. After the alarm is issued, the data processing system 105 will send an instruction to the drone 100 to increase the flight altitude of the drone 100 to hover, expand the monitoring range, and simultaneously take on-site photos.

[0061] As Figure 1 shown, the oil and gas pipeline leakage system further includes: a positioning system 106 and a data transmission system 107. Among them, the positioning system 106 is used to generate positioning data during the cruise of the drone 100. The data transmission system 107 is used to send the positioning data and the inspection results to the remote control center.

[0062] Specifically, the positioning system 106 can real-time locate the flight position of the drone. Further, the positioning system 106 can adopt the GPS positioning method or the Beidou satellite navigation positioning method.

[0063] Specifically, the data transmission system 107 transmits the detection information on the drone 100 to the remote control center so that the staff can make the next move. Further, the data transmission system 107 can combine the information of the data processing system 105 with the positioning system 106 and send it to the remote control center.

[0064] The present invention utilizes the precise cruise system 101 of the drone 100 along the oil and gas pipeline route. The detection system 102 carried on the drone 100 performs real-time detection on the oil and gas pipelines along the way, and processes the detection data in real time. Combining the positioning information, the detection data is combined with the detection location, and finally the detected data information is transmitted to the control center, and the staff can do the next work according to the corresponding situation. The present invention realizes the efficient inspection of the drone along the oil and gas pipeline.

[0065] According to another aspect of the present invention, there is also provided a method for inspecting oil and gas pipeline leakage by a drone, which is executed by a system for inspecting oil and gas pipeline leakage by a drone.

[0066] Figure 2 shows a step flow chart of a method for inspecting oil and gas pipeline leakage by a drone according to an embodiment of the present invention.

[0067] As Figure 2 shown, in step S201, the drone 100 is supported by the precise cruise system 101 to cruise along the laying path of the oil and gas pipeline.

[0068] AsFigure 2 As shown, in step S202, the detection system 102 detects the leakage condition of the oil and gas pipeline to obtain detection data, where the leakage condition includes natural gas leakage and oil leakage.

[0069] As Figure 2 shown, in step S203, the data processing system 105 generates an inspection result based on the detection data.

[0070] In one embodiment, the detection of natural gas leakage is achieved through the following steps: The drone 100 cruises along the oil and gas pipeline under the control of the precise cruising system 101. During the cruising process, the detection system 102 is always in a working state, and the laser probe continuously emits laser to scan the pipeline along the way. When the drone 100 cruises to the natural gas leakage point, the laser spectrum received by the laser receiver is automatically analyzed in the data processing system 105. At this time, the drone 100 will determine that natural gas has leaked at this point, and the data processing system 105 will issue an alarm. At the same time, the flight altitude of the drone 100 is increased and it hovers for shooting. At this time, the detection range of the laser probe is expanded, and the area where natural gas has leaked can be detected in real time. At the same time, a geographical image near the leakage point is taken, combined with the real-time coordinates given by the positioning system 106, and transmitted to the control center through the data transmission system 107 for the staff to quickly carry out emergency rescue work after receiving it.

[0071] In one embodiment, the detection of oil leakage is achieved through the following steps: The drone 100 cruises along the oil and gas pipeline under the control of the precise cruising system 101. During the cruising process, the detection system 102 is always in a working state, and infrared pulses are continuously transmitted in the optical fiber laid along the oil and gas pipeline. Under normal circumstances, the infrared pulses are totally reflected in the optical fiber and do not refract. When the oil and gas pipeline leaks oil, when the oil encounters the rubber that expands when encountering oil outside the optical fiber, the rubber will expand and squeeze the internal optical fiber. At this time, the refractive index of the optical fiber will change, resulting in part of the infrared pulses in the optical fiber not being totally reflected and refracting, so as to shoot outside the optical fiber. When the drone 100 cruises to the oil leakage point, when the photosensitive sensor on the drone 100 receives the infrared pulses refracted from the optical fiber, the data processing system 105 issues an alarm. At the same time, the flight altitude of the drone 100 is increased and it hovers for shooting. A geographical image near the leakage point is taken, combined with the real-time coordinates given by the positioning system 106, and transmitted to the control center through the data transmission system 107 for the staff to quickly carry out emergency rescue work after receiving it.

The computer program can run computer instructions, and the computer instructions include computer program code, which can be in the form of source code, object code, executable file or some intermediate form, etc.

[0073] The computer-readable storage medium can include: any entity or device capable of carrying computer program code, recording medium, USB flash drive, mobile hard disk, magnetic disk, optical disk, computer memory, read-only memory (ROM), random access memory (RAM), electrical carrier signal, telecommunication signal, and software distribution medium, etc.

[0074] It should be noted that the content included in the computer-readable storage medium can be appropriately increased or decreased according to the requirements of legislation and patent practice within the jurisdiction. For example, in some jurisdictions, according to legislation and patent practice, the computer-readable storage medium does not include electrical carrier signals and telecommunication signals.

[0076] 1) Based on the one-way positioning between the UAV and the positioning blocks on the oil and gas pipeline, the cruise route of the UAV can be ensured to be accurate, avoiding the failure to detect some lines, and efficient inspection of oil and gas pipeline leakage can be completed;
