[0033] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] When materials or components generate deformation or cracks during the stress process, the phenomenon of releasing strain energy in the form of elastic waves is called acoustic emission. The technology of using the received acoustic emission signals to perform dynamic non-destructive testing on materials or components is called acoustic emission technology. The acoustic vibration sensor is fixed to the pipeline. When the pipeline is affected by construction, it will generate vibration. After the sensor receives the vibration signal, the weak mechanical vibration is converted into an electrical signal, amplified by an amplifier, and then the construction frequency signal is selected by a band-pass filter for signal processing, and the data is transmitted to the cloud server for users to view and download the vibration waveform in real time.

[0035] Refer to Figure 1 , a third-party construction monitoring device for buried gas pipelines, including a main body housing 1, a battery pack 2, an acoustic vibration sensor assembly 3, an upper cover housing 4, screws 5, a sealing ring 6, a connector 7, a main control board 8, and an antenna 9. A storage groove body is provided inside the main body housing 1. The battery pack 2, the main control board 8, and the connector 7 are all installed inside the housing. One side opening of the main body housing 1 is connected to the upper cover housing 4 by screws 5, and a sealing ring 6 is also provided at the connection position between the upper cover housing 4 and the main body housing 1 to ensure the sealing performance of the connection position between the two.

[0036] Refer to Figure 1 , the acoustic vibration sensor assembly 3 is located outside the main body housing 1, passes through the bottom of the main body housing 1 into the housing through a cable, and is connected to the main control board 8 inside the housing. The main control board 8 is fixed to one side inside the main body housing 1 through the connector 7.

[0037] Furthermore, the battery pack 2 is installed inside the main body housing 1 to supply power to the main control board 8 and the acoustic vibration sensor assembly 3.

[0038] It should be noted that after the main control board 8 is welded, it is connected to the connector 7 and then installed into the main body housing 1. Then, the battery pack 2, the acoustic vibration sensor assembly 3, and the antenna 9 are successively installed into the main body housing 1 and connected to the main control board 8. Finally, after the sealing ring 6 is installed into the groove of the main body housing 1, the upper cover housing 4 is pressed tightly and fastened with screws 5.

[0039] Refer toFigure 2 On the main control board 8, there are an operation MCU, a control MCU, a storage module, an attitude detection sensor, a data acquisition and processing module, an amplifier, a filter, a communication module, and a Bluetooth module. Among them, the control MCU, the storage module, the communication module, and the filter are all connected to the operation MCU. The data acquisition and processing module is connected to the acoustic vibration sensor assembly 3 to receive the data signal from the acoustic vibration sensor assembly 3. The data acquisition and processing module is also connected to the amplifier, and the amplifier is connected to the filter;

[0040] Therefore, when the data acquisition and processing module in the main control board 8 is responsible for processing the analog signal detected in the acoustic vibration sensor assembly 3, it is divided into two parts. First, the collected tiny acoustic vibration signal is amplified, and then the amplified signal is filtered through a fourth-order band-pass filter; the filtered signal will be analyzed and calculated by the operation MCU to determine whether there is third-party construction. When the acquisition, calculation, and communication are completed, the operation MCU enters the sleep state; the operation MCU is connected to the storage module to save the collected original data; the operation MCU is connected to the communication module. If it is determined that there is third-party construction, the operation MCU will upload the judgment result and the original waveform to the cloud server through the communication module.

[0041] Refer to Figure 2 In addition, the control MCU is also connected to a Bluetooth module, and the operation MCU is connected to the control MCU. The control MCU is responsible for power management, waking up the operation MCU for acquisition and calculation every 10 minutes. In addition, when an external Bluetooth device is connected, the operation MCU will also be woken up for acquisition and calculation; the control MCU is connected to the Bluetooth module to communicate with the external Bluetooth system; the control MCU is connected to the attitude detection sensor for anti-theft control.

[0042] The specific operation principle of this application is as follows:

[0043] During use, the acoustic vibration sensor assembly 3 is adsorbed on the pipeline to be measured to collect the acoustic vibration signal on the pipeline. After the acoustic vibration signal is processed by the data acquisition and processing module, it is analyzed and calculated by the operation MCU on the main control board 8. If a construction signal is judged, the judgment result and the original waveform will be uploaded to the cloud through the communication module. After the acquisition, calculation, and communication, the operation MCU goes to sleep, which is done every 10 minutes. In addition, when an external Bluetooth device is connected, the operation MCU will also be woken up for acquisition and calculation; the control MCU is responsible for power management and wakes up the operation MCU to work.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
