AI Technical Summary

Technical Problem

The existing pipeline detection technology has problems such as large positioning errors and high detection failure rates in complex environments, especially when facing mixed signal interference, frequency drift, etc., communication links are prone to failure or misjudgment.

Method used

By extracting the signal characteristics of the standard microwave signals of the multi-frequency communication detection terminal at each operating frequency, a signal characteristic database is constructed, and a hybrid multi-frequency microwave signal in the target pipeline detection area is obtained, and it is decomposed into a single-frequency signal stream. Data channel matching and linking is performed based on single-frequency signal flow information. If data linking fails, a frequency drift compensation model is built to perform frequency compensation to reconnect communication.

Benefits of technology

It realizes signal feature extraction, mixed signal decomposition, dynamic matching of data channels and frequency compensation, improving communication stability between terminals and the accuracy and adaptability of underground pipeline detection.

Abstract

The invention discloses a multi-frequency communication detection terminal control method for pipeline detection. According to the method, by constructing a standard microwave signal feature database of a multi-frequency communication detection terminal, feature matching and decomposition are carried out on mixed multi-frequency microwave signals in a target pipeline area, and precise separation of single-frequency signal flows is achieved. A data channel dynamic matching mechanism of the transmitting end and the receiving end is established based on the decomposed single-frequency signal flow information, modeling is performed in combination with the influence of pipeline environment characteristics on frequency drift, and a frequency drift compensation model with environmental adaptability is constructed. And when the communication link is abnormal, self-adaptive correction is carried out on the signal flow through a real-time environment data acquisition and frequency compensation algorithm, and rapid reconstruction of the communication link is completed. The problem of communication stability caused by frequency drift in a complex pipeline environment is effectively solved, and the reliability and the detection precision of a pipeline detection system are remarkably improved.
