Pipeline gas leakage and power plant partial discharge are both highly concealed and harmful safety hazards. Traditional monitoring methods are difficult to meet the precise prevention and control needs. In the scenario of pipeline gas leakage, natural gas, liquefied petroleum gas, industrial toxic and harmful gases and other transportation pipelines are prone to micro leaks due to corrosion, aging, construction damage, etc. The high-speed injection of leaked gas will produce acoustic signals of specific frequencies. However, such leaks mostly occur in underground pipelines, high-altitude pipe galleries or remote areas, with the characteristics of "multiple points, long lines, concealed locations, and large fluctuations in leakage volume". Early micro leaks are difficult to detect, and once they spread, they can easily cause major safety accidents such as explosions and poisoning; In the scenario of partial discharge detection in power plants, high-voltage switchgear, cable joints, insulators, transformers and other electrical equipment may experience partial discharge under conditions such as insulation aging, poor contact, and moisture. Accompanied by characteristic ultrasonic signals, if partial discharge is not detected in a timely manner, it will gradually exacerbate equipment damage, ultimately leading to short circuits, tripping, and even large-scale power outages. Power equipment is mostly distributed in distribution rooms, outdoor towers and other scenarios, and some equipment is in a high-voltage live state. Conventional monitoring is difficult to investigate up close.

At the same time, with high-resolution beamforming technology, it can quickly collect and identify steady-state and transient sound sources, capture any leakage, partial discharge, or abnormal noise signals in a very short time, and display them in images, greatly improving inspection efficiency and accuracy.
Data recording and analysis
Handheld acoustic imaging devices can record and store detection data, facilitating subsequent analysis and report generation. During the detection process, the device can save the results as high-definition images or videos, fully recording the location and characteristics of abnormal sounds, providing intuitive and reliable basis. Meanwhile, the measurement data can be transmitted to the upper PC via USB for further analysis and management.
