LEAKAGE SIGNAL ANALYSIS METHOD

摘要

A method for determining leak probability of a pipe includes receiving first and second signal data respectively for sound pressure (dB) of the pipe from a leak detection sensor operatively coupled to the pipe, the first and second signal data respectively associated with first and second time durations. The method further includes calculating a Root Mean Square (RMS) value of the first signal data for the first time duration, calculating a RMS average for the second signal data, where the second signal data includes a plurality of RMS values for the second time duration, calculating a RMS standard deviation for the second digital signal, and determining a first leak probability value based on a first excess rate of a first comparison value over the RMS standard deviation, the first comparison value being calculated based on the RMS value of the first signal data and the RMS average for the second signal data.

1. A method for determining leak probability of a pipe, the method comprising:
receiving first and second signal data respectively for sound pressure (dB) of the pipe from a leak detection sensor operatively coupled to the pipe, the first and second signal data respectively associated with first and second time durations; calculating a Root Mean Square (RMS) value of the first signal data for the first time duration; calculating a RMS average for the second signal data, wherein the second signal data includes a plurality of values for the second time duration; calculating a RMS standard deviation for the second signal; and determining a first leak probability value based on a first excess rate of a first comparison value over the RMS standard deviation, the first comparison value being calculated based on the RMS value of the first signal data and the RMS average for the second signal data.
