Abstract

The invention provides a detection and alarm method for preventing third-party construction excavation, which comprises the steps of S1, collecting different types of ground vibration signal samples,and constructing a ground vibration signal sample database; S2, performing dual time-frequency joint decomposition on the collected ground vibration signal samples, and constructing a dual time-frequency joint feature vector of the ground vibration signal samples; S3, constructing a deep learning model for ground vibration signal detection through the dual time-frequency joint feature vector; S4,carrying out prediction and classification on the detected ground vibration signals by using the deep learning model, and giving an alarm for the construction condition with excavation activities. Theinvention provides a simple and feasible detection and alarm method for preventing third-party construction excavation, real-time detection and alarm are carried out for the third-party constructionexcavation activities, unified safety protection is carried out on underground pipelines, and the safe operation of the underground pipelines is effectively guaranteed.

Description

technical field [0001] The invention relates to a method for signal detection and pattern recognition, and more specifically, to a detection and alarm method for preventing construction excavation by a third party. Background technique [0002] Urban underground pipelines are important urban infrastructure and the "lifeline" for the organic connection and operation of various functional areas in the city. Once they are excavated and damaged, they will cause serious economic losses and hidden safety hazards. In practice, various types of pipelines are buried at different depths underground, and many construction activities do not fully grasp the specific situation of buried pipelines before excavating the road surface, and do not formulate a complete excavation plan to protect underground pipelines. It is easy to cause damage to underground pipelines during the process. On the other hand, the layout of underground pipelines is complex and diverse. It is costly to install sen...
