Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline monitoring piles, in particular to a novel gas monitoring pile. Background Art

[0002] With the development of industrial economy, oil and natural gas have become an indispensable energy source in people's life and production process. Leakage may occur during transportation, petrochemical product production and use. The leakage of industrial gas not only pollutes the environment, but also causes disasters such as fire and explosion if not handled in time, causing significant loss of life and property, becoming one of the major disasters in the current industrial production and transportation fields. In addition, carbon emissions are also an important international topic. Therefore, countries around the world attach great importance to the research and development and use of rapid and effective leakage telemetry or detection technology and instruments.

[0003] In order to better monitor the leakage of gas pipelines, the Chinese utility model patent application with application number CN202020672635.7 discloses a gas leakage and fire drone intelligent monitoring and processing system, which uses a drone as a system platform, including an ARM development board, an image processing unit, a communication unit, an infrared sensor unit, a positioning unit and an automatic control valve. However, since the gas monitoring piles are usually installed underground or on the ground, the scheme does not take into account the monitoring of the vibration conditions of the surrounding environment. If there are environmental factors such as heavy rain, landslides, and wild animal movement, the pile foundation may be damaged, causing the pile foundation to sink, tilt or break, affecting the leakage detection. Accuracy and reliability make it impossible to accurately locate the leakage point, increasing the risk of danger caused by leakage; in addition, the solution does not take into account the assessment of the severity of gas leakage by vibration intensity, so it is impossible to accurately assess the severity of the leakage, which may lead to misjudgment or neglect of the leakage, missing the best warning and disposal opportunities, and increasing the possibility of danger; secondly, outdoor monitoring devices usually need to run for a long time. If the battery is damaged, it may cause power outages, short circuits, overheating and other problems in the equipment, which will not only lose monitoring data and have a serious impact on the monitoring results and even lead to wrong decisions, but also damage the equipment itself, posing a safety threat to the surrounding environment and personnel.

[0010] Preferably, the deformation monitoring module comprises a PIR motion detector and a CMOS image sensor.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 As shown, the utility model provides a new type of gas monitoring pile, including a monitoring pile body 1, a gas collection device 2 installed at the bottom of the monitoring pile body 1, and a box 3 installed on the monitoring pile body 1, wherein the box 3 is provided with a battery 21 for power supply, a central control board 22, an SD storage card 23, and a vibration monitoring module 13, and the monitoring pile body 1 is also equipped with a 4G / 5G communication module 31, a GPS positioning module 32, a deformation monitoring module 11, and a gas monitoring module 12. The deformation monitoring module used in this embodiment is an infrared touch camera, the gas monitoring module is a gas detection sensor, and the vibration monitoring module is a vibration sensor.

[0021] The novel gas monitoring pile also includes a housing 4, the monitoring pile body 1 is installed in the housing 4, the housing 4 is provided with a louver structure aperture 5, the aperture 5 is matched with the gas detection sensor 12. The central control board 22 also includes a debugging interface, and the central control board 22 is connected to the SD storage card 23 via a USB data storage interface.

[0022] It should be noted that, in this embodiment, the new gas monitoring pile is installed above the gas pipeline, near the gas valve.

[0023] like Figure 2As shown, in order to improve the reliability and stability of the system, the present embodiment further designs a power management circuit and an overvoltage, undervoltage, and overcurrent protection circuit, including a power supply BT1, the power supply BT1 is respectively connected in parallel with the first capacitor C1, the second capacitor C2, and the third capacitor C3; the power supply BT1 is connected in series with the Schottky diode D1 and the ordinary diode D2; the power supply BT1 is connected in series with the first resistor R1 and the voltage regulator diode D3; the two ends of the power supply BT1 are grounded, and the one end of the power supply BT1 is electrically connected to the supply voltage VCC through the Schottky diode D1, the first resistor R1, and the second resistor R2 in sequence.

[0024] Through the above circuit, this embodiment uses the first capacitor C1, the second capacitor C2, and the third capacitor C3 to balance the battery voltage, increase the instantaneous output current, reduce the number of battery alternating charge and discharge times, and improve the reliability and stability of the system; uses the Schottky diode D1 to prevent the battery from being reversed; uses the ordinary diode D2, the first resistor R1, the voltage regulator diode D3, and the second resistor R2 to design an overvoltage, undervoltage, and overcurrent protection circuit to protect the device from voltage, current, and other problems during the power supply process, thereby ensuring electricity safety and reducing safety hazards.

[0025] like Figure 3 As shown, the working principle of the new gas monitoring pile of this embodiment is as follows: when monitoring the gas pipeline, the new gas monitoring pile of this embodiment collects images, gas, and vibration data through the data acquisition layer, namely the infrared touch camera 11, the gas detection sensor 12, and the vibration monitoring module 13, respectively, and then transmits the data to the central control board 22 in real time. The central control board 22 performs preliminary processing on the collected data and stores the processed data in the SD storage card 23. The GPS positioning module is used to mark the location information for the system. The central control board 22 transmits the processed data to the system platform layer through the data transmission layer, namely the 4G / 5G communication module 31. At the same time, the system platform layer issues an operation instruction, which is transmitted to the central control board 22 through the 4G / 5G communication module 31 to realize remote monitoring and control functions, so that the operator can remotely access the monitoring data and increase the practicality of the monitoring pile. Among them, a gateway is also provided on the central control board 22, which can provide a standard network interface and network switching and routing functions for the new gas monitoring pile access equipment, monitor the network status of the access equipment, and support data encryption and communication mode expansion. In addition, the present embodiment further includes a wireless dedicated data communication module. When there is no signal coverage, the central control board 22 communicates data with the unmanned aerial vehicle onboard data pod via the wireless dedicated data communication module.

[0026] In order to better realize the real-time processing and transmission of image information of the utility model and meet the low power consumption requirements, in this embodiment, the infrared touch camera 11 uses a combination of a PIR motion detector and a CMOS image sensor. The PIR motion detector can identify objects by detecting heat, does not require the support of an external light source, is suitable for use in low-light environments, and has the characteristics of fast response speed, low power consumption, stability and reliability. The CMOS image sensor is used for photo capture, and has the characteristics of high integration, fast response speed, low cost, and low power consumption. Data transmission uses BLE Bluetooth (Bluetooth LowEnergy), which has extremely low power consumption and can extend the battery life of the device. The BLE Bluetooth chip has a low cost and is more suitable for mass production of consumer-level projects.

[0027] In addition, in this embodiment, the central control board 22 is responsible for power supply management of the infrared touch camera 11, the gas detection sensor 12, the vibration monitoring module 13, the 4G / 5G communication module 31, the GPS positioning module 32, the debugging interface 24, and the USB data storage interface, and supplies power on demand. The battery 21 adopts a 3.7V lithium battery 18650 specification.

[0028] The working principle of the infrared touch camera 11 of this embodiment is as follows: after the parameters are initialized, periodic photos are taken and image data are uploaded to the central control board 22; the working principle of the gas detection sensor 12 is as follows: after the parameters are initialized, periodic sampling is performed to determine whether the sampled data contains gas components. If so, the gas data is uploaded to the central control board 22; the working principle of the vibration monitoring module 13 is as follows: after the parameters are initialized, if the surrounding environment is abnormal (vibration), photos are taken and recorded.

[0029] Since gas monitoring piles are usually installed underground or on the ground, they are easily affected by external factors such as surrounding construction, man-made damage, landslides, and heavy rains. For example, heavy rains may cause the groundwater level to rise, which will create additional pressure on the gas monitoring piles. Landslides may cause the pile foundation to sink, tilt, or break, affecting the accuracy of the gas monitoring piles. Vibration monitoring can effectively identify surrounding construction, man-made damage, landslides, and other situations. Monitoring the vibration of the surrounding environment of the pipeline can help to timely detect potential pipeline damage or wear, and perform maintenance and repair in advance to extend the service life of the pipeline. In addition, when a gas pipeline leaks, the leak point is usually accompanied by a certain degree of vibration. This vibration may be caused by the impact of the airflow generated when the gas leaks, or by the interaction between the leaked gas and the surrounding environment. By monitoring the surrounding vibration, the leak point can be located in time to improve maintenance efficiency.

[0030] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
