AI Technical Summary
Existing technologies cannot achieve real-time, comprehensive, and 24/7 monitoring of damage to urban underground gas pipelines caused by third-party construction. In particular, there is a lack of effective means to deal with blind and reckless construction activities, resulting in a high risk of gas pipeline damage and leakage.
Acoustic emission sensing technology is used to monitor acoustic wave information near the pipeline in real time by installing acoustic emission probes and data acquisition and transmission devices in the gas pipeline's auxiliary facilities. Combined with early warning models, construction signals are identified and early warnings are issued through a remote server.
It enables real-time monitoring of third-party construction damage that is trenchless, has a wide monitoring range, accurate identification, and low cost, thus ensuring the safety of urban gas pipeline networks.
