| Summary: | The scientific community has developed many ways to
ensure the safety of transportation of petroleum products by
automated means. An urgent task is to increase the efficiency
of identifying the type of unauthorized impact on the pipeline
and assess the errors probabilities in the detection of violations.
The paper presents the results of an experimental assessment
of the probabilistic characteristics of the detector based on the
previously proposed active vibro-acoustic method of control.
The values of informative features in vibroacoustic signals are
obtained depending on the size of the local heterogeneity and
the signal-to-noise ratio. The probability of recognition error and
the required number of accumulated signals for system operation
in the far zone are determined. The conclusion is made about the
consistency of the proposed algorithm for identifying the type of
unauthorized exposure. |
