[0021] This embodiment provides a station valve chamber pipeline container leakage acoustic array monitoring and positioning device, which includes a detection station 2, a monitoring component 3, and a connecting sleeve 7. After the monitoring component 3 is positioned and installed inside the pipeline 1 through the connecting sleeve 7, the pressure sensor inside the transmission cavity 51 monitors the pressure intensity of the flowing medium inside the pipeline 1 in real time. The acoustic array sensor performs ultrasonic monitoring on the space where the flowing medium enters the transmission cavity 51 from the connecting groove 41. Monitoring is carried out in a small transmission space, reducing the environmental noise generated during the medium transmission process and improving the accuracy of monitoring. The distributed fiber optic sensor 62 can monitor the vibration position generated during the transmission of the flowing medium. It can demodulate the phase of the scattered light caused by external vibrations such as leakage impacts and invert the vibration signal by demodulating the phase change. The acoustic array sensor and temperature sensor on the surface of the detection rod 21 monitor the outer ring of the pipeline 1. The system monitors the ultrasonic and temperature environment of the pipe, removes broadband noise based on the frequency characteristics of the sound waves, and focuses on high-frequency leakage sound signals. It can monitor abnormal sound wave transmission and abnormal temperature changes on the outside of the pipe during leakage, and can feed the monitoring data back to the network transmission layer in real time. It can monitor and combine multiple sets of diverse data, and then calculate and process the monitoring data to accurately locate the leak. Multiple monitoring elements are arranged in an array to focus on the characteristic frequency band of the leak, improving the accuracy of monitoring. Moreover, it can enhance the signal in a specific direction through phase weighting to generate a sound source distribution map.

It analyzes data to assess safety, formulates maintenance plans, optimizes monitoring schemes, and integrates with industrial production systems to achieve collaborative management.

[0022] In a further embodiment of this invention, the pipe 1 is uniformly arranged into multiple sets of pipes, each set of pipes is equipped with a monitoring component 3 inside, each set of pipes is surrounded by a locking ring 11, and each set of pipes is equipped with a warning light 12 on its outer wall.

[0023] In this embodiment, the warning light 12 can flash to warn of a leak in the area.

[0024] In a further embodiment of this invention, a through groove 41 is provided inside the connector 4, and a transmission cavity 51 is disposed inside the through groove 41, extending into the convex disc 73 and threadedly connected to the through groove 41.

[0025] In this embodiment, the deep protrusion 73 can lock the connector 4 inside the pipe 1, and support and position it.

[0026] In a further embodiment of this invention, the number of positioning seats 5 is set to two sides and symmetrically arranged. Each of the two positioning seats 5 has a connector 4 on its outer side. The two transmission cavities 51 are fitted together, and the pressure sensors inside the transmission cavities 51 are arranged in a circular pattern on the inner wall of the transmission cavities 51.

[0027] In this embodiment, the pressure sensor inside the transmission cavity 51 monitors the pressure intensity of the medium flowing inside the pipe 1 in real time, and the acoustic array sensor performs ultrasonic monitoring on the medium flowing into the space of the transmission cavity 51 from the connecting groove 41. Monitoring is carried out in a small transmission space, which reduces the environmental noise generated during the medium transmission process and improves the accuracy of monitoring.

[0028] In a further embodiment of this invention, the top and bottom of the positioning seat 5 are provided with mounting grooves 54, and the mounting seat 6 is provided with a locking screw 61 through the interior, which matches the mounting groove 54.

[0029] After the mounting base 6 in this embodiment is positioned and installed, the distributed optical fiber sensor 62 can monitor the vibration position generated during the transmission of the circulating medium. It can demodulate the phase change of the scattered light caused by external vibrations such as leakage impacts and invert the vibration signal.

[0030] In a further embodiment of this invention, the connecting sleeve 7 is hollow, the surface of the positioning ring 71 is fixedly provided with a connecting plate 72, and the connecting head 4 is provided with positioning bolts evenly running through its interior and connected to the connecting plate 72.

[0031] In this embodiment, the medium inside the pipe 1 is transmitted into the connecting groove 41 through the connecting sleeve 7 and then through the transmission cavity 51. After passing completely through the monitoring component 3, it is then transmitted back into the pipe 1 through the connecting sleeve 7 on the other side.

[0032] In a further embodiment of this example, the number of monitoring components 3 is set to multiple and the distance between two adjacent monitoring components 3 is set to 3-5km.

[0033] In this embodiment, the monitoring component 3, after being positioned and installed as required, can provide full-time and space-wide monitoring of leakage events on pipeline 1.

[0034] Example 2: See Figure 5 and Figure 6 Based on Example 1, this example proposes a method for monitoring and locating leaks in pipeline containers in station valve chambers using an acoustic array, comprising the following steps: Step 1: Install multiple monitoring components 3 sequentially inside the pipeline, and install the detection station 2 and warning light 12 on the outside of the corresponding monitoring components 3; Step 2: The pressure sensor inside the transmission cavity 51 monitors the pressure intensity of the medium flowing inside the pipe 1 in real time. The acoustic array sensor performs ultrasonic monitoring of the medium flowing into the transmission cavity 51 from the connecting groove 41. The distributed optical fiber sensor 62 can monitor the vibration position generated during the transmission of the medium. The acoustic array sensor and temperature sensor on the surface of the detection rod 21 monitor the ultrasonic and temperature environment outside the pipe 1 and can feed back the monitoring data to the network transmission layer in real time. Step 3: By integrating different data feedbacks within the same location, it can be determined whether a leak has occurred in the corresponding pipeline 1. If a leak occurs, the data transmission module sends an alarm signal to the platform layer, and the warning light 12 flashes to warn the user.

[0035] This embodiment provides a method for monitoring and locating leaks in pipeline containers in station valve chambers using an acoustic array. It utilizes the mechanism that when high-pressure gas is ejected from a leak hole, the pressure difference causes rapid gas expansion, forming high-speed turbulence and eddies at the hole opening. This turbulence interacts with the surrounding medium, generating broadband sound waves. The sound pressure near the leak point is strong and attenuates with distance. It also considers the pressure intensity inside the pipeline and the vibration changes during medium transmission when a leak occurs. The method determines whether a leak has occurred by considering the time difference Δt between the leaking sound waves and the arrival time at different sensors. The "distance difference" from the sound source is obtained using Δd = v·Δt (where v is the speed of sound). Multiple sensors form a hyperbola intersection solution, allowing for a rough pointing followed by precise location to confirm the leak position. Furthermore, during monitoring, the sound signal energy can be calculated and compared with a threshold value. Adapting to dynamic thresholds achieves accurate monitoring. When a leak occurs during monitoring, the system scans the space to find the direction of the sound energy peak. The system accurately calculates the time difference of arrival at different sensors, then calculates the coordinates of the leak source. The method for combining the leak source coordinates is: beamforming → coarse pointing, TDOA → fine positioning. It can monitor abnormal sound wave transmission and abnormal temperature changes generated on the outside of pipe 1 during leakage, and can also feed the monitoring data back to the network transmission layer in real time. It can realize the monitoring and combination of multiple sets of diverse data, and then calculate and process the monitoring data to accurately locate the leak. Multiple monitoring elements are arranged in an array to focus on the characteristic frequency band of the leak, improving the accuracy of monitoring. Moreover, it can enhance the signal in a specific direction through phase weighting to generate a sound source distribution map. The platform layer data analysis module uses deep learning algorithms to identify the degree and location of the leak, and combines historical data to predict the risk of leakage, improving the monitoring accuracy in complex environments. It analyzes data to assess safety, formulates maintenance plans, optimizes monitoring schemes, and integrates with industrial production systems to achieve collaborative management.

[0036] In a further embodiment of this invention, multiple detection stations 2 are arranged evenly. The detection rods 21 inside the detection stations 2 can be cylindrical, annular, quadrilateral, or polygonal as needed. They are set and installed according to different detection positions and requirements. Multiple detection stations 2 and monitoring components 3 constitute a signal acquisition layer. The signal acquisition layer is used to acquire leakage signals in real time and convert them into electrical signals. The signal processing module is used to retain leakage characteristics while removing broadband noise and focusing on high-frequency leakage sound signals to improve the signal-to-noise ratio of subsequent detection and positioning.

[0037] In this embodiment, the signal processing module can retain leakage characteristics while removing broadband noise, focusing on high-frequency leakage sound signals to improve the signal-to-noise ratio for subsequent detection and localization. Referring to parameters with obvious high-frequency components (usually 2kHz~60kHz), the high-frequency band helps to distinguish industrial background noise. The spectral peak is related to the leakage aperture, gas type, and pressure. The characteristic of energy attenuation with the square of distance improves the accuracy of monitoring data. During the monitoring process, multiple sensors in the signal acquisition layer are arranged according to rules, such as rectangular arrays or circular arrays. The signals of each sensor are weighted and summed according to the spatial direction. Based on the characteristics of coherent superposition of signals in the target direction for beam enhancement and phase-shifted beam suppression of signals in non-target directions, different angles can be scanned to form a spatial sound energy distribution map.

[0038] In a further embodiment of this example, the signal acquisition layer output is provided with a network transmission layer. The network transmission layer is used to receive electrical signals for filtering, noise reduction, and feature extraction to reduce data volume. It also uses preset rules to identify suspected leaks and issue warnings. The network transmission layer output is connected to a platform layer via a communication module. The platform layer includes a data storage center, a data analysis module, and a device management module. The platform layer is connected to an application layer via a transmission cable. The application layer includes a monitoring and early warning module, a decision support module, and a remote monitoring module.

[0039] In this embodiment, the network transmission layer includes an edge computing node module, which receives electrical signals for filtering, noise reduction, and feature extraction to reduce data volume. It uses preset rules to identify suspected leaks and issue warnings, improving the speed and efficiency of leak detection. The platform layer's data storage center can use distributed databases and cloud storage to securely store raw acoustic data, feature data, and device status data, supporting efficient queries. The data analysis module can perform machine learning and deep learning algorithms to identify leaks (degree, location) and predict leak risks based on historical data. The device management module can uniformly manage sensors, edge nodes, and other devices, performing device configuration, status monitoring, and fault maintenance. The application layer's monitoring and early warning module can intuitively display real-time status (leakage status, location, degree) and trigger audible and visual alarms when a leak occurs. The decision support module can analyze data to assess security, formulate maintenance plans, optimize monitoring schemes, and integrate with industrial production systems for collaborative management. The remote monitoring module can feed data back to mobile phones / tablets for remote data viewing and early warning reception, enabling monitoring anytime, anywhere.
