Abstract
This disclosure describes systems and methods for detecting passing valves. A method includes measuring vibrational data with a sensor coupled to a pipe adjacent to a valve; generating a spectrogram representing a time variation of frequencies of the vibrational data; detecting that the valve is a passing valve by classifying the spectrogram as including frequencies representative of a passing valve, the classifying being based on a trained convolutional neural network; and in response to detecting the passing valve, performing a corrective action to resolve the passing valve.

A method for detecting passing valves, the method comprising:
- measuring vibrational data with a sensor coupled to a pipe adjacent to a valve;
- generating a spectrogram representing a time variation of frequencies of the vibrational data;
- detecting that the valve is a passing valve by classifying the spectrogram as including frequencies representative of a passing valve, the classifying being based on a trained convolutional neural network;
- and
- in response to detecting the passing valve, performing a corrective action to resolve the passing valve.
A system for detecting passing valves, the system comprising:
- a piezoelectric sensor coupled to a pipe adjacent to a valve;
- at least one processor and a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
- measuring vibrational data with a sensor coupled to a pipe adjacent to a valve;
- generating a spectrogram representing a time variation of frequencies of the vibrational data;
- detecting that the valve is a passing valve by classifying the spectrogram as including frequencies representative of a passing valve, the classifying being based on a trained convolutional neural network;
- and
- in response to detecting the passing valve, performing a corrective action to resolve the passing valve.
