Description

Technical Field

[0001] The present application relates to the technical field of transport pipeline detection, and in particular to a method and system for monitoring operating equipment based on infrasound waves. Background Art

[0002] Pipeline transportation of natural gas is currently recognized by the industry as the most economical, efficient, and safest method of transportation. However, to ensure the safe, stable, and efficient operation of gas pipelines, regular maintenance procedures such as pigging and internal inspections have become essential. These pigging and internal inspections are not only crucial to the normal operation of the pipelines but also to the safety of natural gas transportation.

[0003] Pipeline cleaning operations present significant risks due to the inherent dangers of natural gas and potential equipment blockages. Therefore, these risks must be identified and controlled to ensure smooth pigging and internal inspection operations.

[0004] One of the key factors determining the success of pipeline pigging and internal inspection operations is the operating speed of the equipment. Pigging (and internal inspection) is most effective when performed at an appropriate speed. Operating the equipment at too high or too low a speed can negatively impact the operation and may even lead to serious safety hazards. Summary of the Invention

[0005] In order to solve the above problems, the embodiments of the present application provide a method, system and system for monitoring operating equipment based on infrasound waves.

[0006] In order to solve the above technical problems, the present application provides a method for monitoring operating equipment based on infrasound, comprising:

[0007] Obtain real-time running speed information of running equipment in pipelines;

[0008] encoding the running speed information to obtain a target infrasonic frequency;

[0009] generating an infrasound wave based on the target infrasound wave frequency, and emitting the infrasound wave;

[0010] receiving, at a detection point preset on the outer wall of the pipeline, an infrasound wave signal of the infrasound wave propagating along the pipeline wall;

[0011] Decoding the infrasound signal to obtain decoding speed information;

[0012] The operating status of the operating device is obtained based on the decoding speed information to reflect the detection operation risk of the operating device.

[0013] The beneficial effects are:

[0014] In the technical solution provided in the embodiments of the present application, while the operating equipment is operating in a pipeline, the operating speed information of the operating equipment is acquired in real time. This operating speed information is encoded to obtain a target infrasonic frequency. Based on the target infrasonic frequency, an infrasonic wave is generated and then transmitted along the pipeline wall. This infrasonic wave, which propagates along the steel pipe wall, enables long-distance communication between the operating equipment within the pipeline and equipment outside the pipeline, overcoming the limitation of existing technologies that prevent long-distance communication between equipment within the pipeline and equipment outside the pipeline. Subsequently, at a predetermined detection point on the pipeline's outer wall, the received infrasonic wave propagating along the pipeline wall is decoded to obtain decoded speed information. Based on this decoded speed information, the operating status of the operating equipment can be determined to reflect the risk of the operating equipment's inspection operation. In this way, through infrasonic communication, the operating speed of the operating equipment within the pipeline can be acquired in real time, effectively improving pipeline inspection efficiency and reducing labor costs. It can also monitor the operating status of equipment in the pipeline in real time by decoding speed information, and promptly detect and handle abnormal situations such as equipment blockage, so as to reduce the risks of pigging and internal inspection operations, reduce the incidence of pipeline accidents, and ensure the safety, stability and efficiency of pigging and internal inspection operations.

[0015] In a second aspect, the present invention provides an operating equipment monitoring system based on infrasound, comprising a speed sensor, an infrasound structure, a receiver, and a monitoring system;

[0016] The speed sensor and the infrasonic wave structure are disposed on the operating device, the speed sensor being connected to the infrasonic wave structure and configured to transmit real-time acquired operating speed information to the infrasonic wave structure; the infrasonic wave structure being configured to encode the operating speed information to obtain a target infrasonic wave frequency; generating infrasonic waves based on the target infrasonic wave frequency, and emitting the infrasonic waves;

[0017] The receiver is arranged at a detection point preset on the outer wall of the pipeline, and is used to receive the infrasound wave signal propagating along the pipeline wall, and decode the infrasound wave signal to obtain decoding speed information;

[0018] The monitoring system is connected to the receiver, and is used to receive the decoding speed information for display, and obtain the operating status of the operating equipment based on the decoding speed information to reflect the detection operation risk of the operating equipment.

[0028] To address the significant safety risks associated with existing natural gas pipeline pigging and internal inspection operations, which arise from the hazardous nature of natural gas and the potential for obstruction of operating equipment such as pigs and internal detectors. In particular, in pipelines with low throughput and numerous obstructions, the operating speed and status of operating equipment are difficult to monitor in real time, hindering the smooth progress of pigging and internal inspection operations. The present invention proposes an infrasound-based operating equipment monitoring method and apparatus, electronic equipment, and computer-readable storage medium. These methods primarily relate to infrasound-based operating equipment monitoring technology, as part of natural gas pipeline inspection technology. These embodiments are described in detail below.

[0029] First see Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for monitoring operating equipment based on infrasound waves, as shown in an exemplary embodiment of the present application. Figure 1 As shown, in an exemplary embodiment, the operating equipment monitoring method based on infrasound waves may include steps S101 to S106, which are described in detail as follows:

[0030] Step S101: obtaining in real time the running speed information of the running equipment when running in the pipeline.

[0031] Step S102: Encode the running speed information to obtain the target infrasound frequency.

[0032] Step S103: Generate infrasound waves based on the target infrasound wave frequency and transmit the infrasound waves.

[0033] Step S104: receiving an infrasound wave signal propagating along the pipe wall at a preset detection point on the outer wall of the pipe.

[0034] Step S105: Decode the infrasound signal to obtain decoding speed information.

[0035] Step S106 , obtaining the operating status of the operating equipment based on the decoding speed information to reflect the detection operation risk of the operating equipment.

[0036] In order to grasp the operating status of operating equipment such as pipe cleaners and internal detectors in real time, this embodiment first obtains the operating speed information of the operating equipment in real time. In order to overcome the limitation of existing technologies that cannot realize long-distance communication between operating equipment in the pipeline and the outside of the pipeline, this embodiment uses the characteristics of infrasound propagation on the steel pipe wall to encode the operating speed information to obtain a target infrasound frequency, and generates infrasound based on the target infrasound frequency. The infrasound is then transmitted and propagated along the pipeline wall so that a preset detection point on the outer wall of the pipeline can receive the infrasound signal propagated along the pipeline wall. The infrasound signal is then decoded to obtain decoded speed information. The operating status of the operating equipment is obtained based on the decoded speed information, and the operating speed information and operating status of the operating equipment are displayed in real time to reflect the detection operation risk of the operating equipment.

[0037] As can be seen from the above, the method provided in this embodiment utilizes the characteristics of infrasound propagating on steel pipe walls to achieve long-distance communication between equipment running inside the pipeline and equipment outside the pipeline, breaking through the limitation of existing technologies that cannot achieve long-distance communication between equipment running inside the pipeline and outside the pipeline, and ensuring the reliability and accuracy of information transmission. On the other hand, through infrasonic communication, the operating speed of equipment running inside the pipeline can be obtained in real time, effectively improving the efficiency of pipeline inspection and reducing labor costs. It is also possible to monitor the operating status of equipment running inside the pipeline in real time by decoding speed information, so as to promptly detect and handle abnormal conditions such as equipment blockage, thereby reducing the risks of pipeline cleaning and internal inspection operations, reducing the incidence of pipeline accidents, and ensuring the safety, stability and efficiency of pipeline cleaning and internal inspection operations.

[0038] In an exemplary embodiment provided by the present application, the infrasound wave corresponding to the running speed information is obtained by using the correspondence between the preset speed information and the infrasound wave frequency. The specific steps may include:

[0039] Obtaining the corresponding relationship between preset speed information and infrasound frequency;

[0040] Frequency modulation coding technology is used to map the running speed information to the corresponding infrasound frequency based on the corresponding relationship to obtain the target infrasound frequency.

[0041] In this embodiment, the running speed information of the running device can be encoded into infrasound waves of different frequencies. The specific encoding method can adopt frequency modulation (FM) encoding technology to map the running speed information to the corresponding infrasound wave frequency. The target infrasound wave frequency corresponding to the running speed information is obtained through the correspondence between the preset speed information and the infrasound wave frequency.

[0042] In another exemplary embodiment, the encoded infrasound wave is generated by an acoustic wave transducer, and thus the step of obtaining the infrasound wave based on the target infrasound wave frequency may specifically include:

[0043] generating a target voltage signal based on a target infrasound frequency;

[0044] performing power amplification processing on the target voltage signal to obtain an amplified target voltage signal;

[0045] The amplified target voltage signal is input into the acoustic wave transducer to generate infrasound waves, which are then emitted.

[0046] In this embodiment, the infrasonic oscillator generates an electrical signal below 20 Hz as a target voltage signal based on a set frequency parameter, namely the target infrasonic frequency. This target voltage signal is amplified by a power amplifier to enhance the signal strength, ensuring that the generated infrasonic wave can propagate a long distance within the pipeline. The amplified target voltage signal is then input into the acoustic transducer to generate infrasonic waves, which then propagate along the pipeline wall. Due to the low frequency of infrasonic waves, they travel a long distance with minimal energy attenuation, allowing them to be effectively transmitted to the exterior of the pipeline.

[0047] In an exemplary embodiment provided by the present application, an acoustic wave sensor is provided at a preset detection point on the outer wall of the pipeline to receive an infrasound wave signal propagating along the pipeline wall. The specific steps may include:

[0048] After being emitted, the infrasound waves propagate along the outer wall of the pipe, and the sensor signals detected by the acoustic wave sensor are obtained in real time at the preset detection points on the outer wall of the pipe;

[0049] The sensor signal is filtered and amplified to extract the infrasound signal corresponding to the infrasound wave.

[0050] Due to pipeline construction requirements, pipelines for transporting natural gas will plan exposed pipeline sections after setting a specified underground pipeline length to facilitate inspection and maintenance operations. Therefore, in this embodiment, preset detection points are set on the outer wall of the exposed pipeline, and acoustic wave sensors are installed to detect the vibration signal generated by the propagation of infrasound along the pipe wall as the sensor signal. The received signal is then filtered and amplified to eliminate noise and interference and extract the effective infrasound signal.

[0051] In another exemplary embodiment, the specific steps of decoding the infrasound wave signal to obtain the decoding speed information may include:

[0052] The infrasound signal is decoded using a preset decoding algorithm to obtain decoding speed information. The preset decoding algorithm is a reverse technology of the frequency modulation coding technology.

[0053] The above-mentioned embodiment provided by the present application obtains the infrasonic wave signal of the infrasonic wave propagating along the pipeline wall through the acoustic wave sensor, and then uses a preset decoding algorithm (the inverse technology of frequency modulation coding technology) to convert the infrasonic wave signals of different frequencies into corresponding running equipment speed information, thereby realizing long-distance communication between the running equipment in the pipeline and the equipment outside the pipeline, obtaining the running speed of the running equipment in the pipeline in real time, effectively improving the detection efficiency in the pipeline, and reducing labor costs.

[0054] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a system for monitoring operating equipment based on infrasound, as shown in an exemplary embodiment of the present application. Figure 2 As shown, the infrasound-based operating equipment monitoring system includes a speed sensor 210 , an infrasound structure 220 , a receiver 230 and a monitoring system 240 .

[0055] The speed sensor 210 and the infrasonic wave structure 220 are arranged on the running equipment. The speed sensor 210 is connected to the infrasonic wave structure 220 and is used to transmit the real-time running speed information to the infrasonic wave structure 220; the infrasonic wave structure 220 is used to encode the running speed information to obtain the target infrasonic wave frequency; generate infrasonic waves based on the target infrasonic wave frequency, and emit infrasonic waves.

[0056] The receiver 230 is set at a detection point on the outer wall of the exposed pipeline in the pipeline line, and is used to receive the infrasound wave signal propagating along the pipeline wall and decode the infrasound wave signal to obtain decoding speed information.

[0057] The monitoring system 240 is connected to the receiver and is used to receive the decoding speed information for display, and obtain the operating status of the operating equipment based on the decoding speed information to reflect the detection operation risk of the operating equipment.

[0058] In another exemplary embodiment provided by the present application, the infrasonic structure includes an encoder, an infrasonic oscillator, an acoustic transducer and a transmitter. The encoder is used to obtain the correspondence between preset speed information and infrasonic frequency; the operating speed information is mapped to the corresponding infrasonic frequency based on the correspondence using frequency modulation coding technology to obtain a target infrasonic frequency; the infrasonic oscillator is connected to the encoder to generate a target voltage signal based on the target infrasonic frequency; the target voltage signal is power amplified to obtain an amplified target voltage signal, and the amplified target voltage signal is input into the acoustic transducer; the acoustic transducer is connected to the transmitter to generate infrasonic waves based on the amplified target voltage signal, and the infrasonic waves are emitted by the transmitter.

[0059] The receiver includes an acoustic sensor and a decoder. The acoustic sensor is located at a detection point on the outer wall of an exposed pipe in the pipeline and is connected to the decoder. The acoustic sensor detects the vibrations generated by the infrasound waves propagating along the outer wall of the pipe in real time, generating a sensor signal. This sensor signal is then filtered and amplified to extract the corresponding infrasound signal. The decoder decodes the infrasound signal using a pre-set decoding algorithm, a reverse-engineered version of frequency modulation coding, to obtain decoding speed information.

[0060] It can be seen from this that the infrasound-based operating equipment monitoring system provided in the above embodiment applies the infrasound-based operating equipment monitoring method provided in this application. On the one hand, it utilizes the characteristics of infrasound propagation on the steel pipe wall to achieve long-distance communication between the operating equipment in the pipeline and the equipment outside the pipeline, breaking through the limitation of the existing technology that the operating equipment in the pipeline cannot achieve long-distance communication with the outside of the pipeline, and ensuring the reliability and accuracy of information transmission. On the other hand, through infrasound communication, the operating speed of the operating equipment in the pipeline can be obtained in real time, effectively improving the efficiency of pipeline inspection and reducing labor costs. It can also monitor the operating status of the operating equipment in the pipeline in real time by decoding speed information, and promptly detect and handle abnormal conditions such as operating equipment blockage, thereby reducing the risks of pipe cleaning and internal inspection operations, reducing the incidence of pipeline accidents, and ensuring the safety, stability and efficiency of pipe cleaning and internal inspection operations.
