Abstract: A system and method for verifying a connection between a first and second connector. The system includes a transducer and a processor. The processor is configured to determine a velocity of the first connector when the first connector is moved to the second connector to form a coupling, calculate a time interval to the coupling based on the velocity detected at the set point and a position of the second connector, and receive, from the transducer, a signal during the time interval. The signal includes the sound generated when the coupling is formed. The processor analyzes the signal and identifies the sound of the coupling within the signal. The signal is filtered in the frequency domain and in the time domain, resulting in a filtered spectrogram. The spectrogram is compared to a pattern. The processor determines if the first and second connector are properly coupled based on the comparison.

Abstract: A system and method for verifying a connection between a first connector and a second connector. The system includes an audio transducer and an electronic processor. The electronic processor is communicatively coupled to the audio transducer. The electronic processor is configured to determine a velocity of the first connector when the first connector passes a set point when the first connector is moved to the second connector to form a coupling. The coupling generates a sound. The electronic processor calculates a time interval to formation of the coupling based on the velocity detected at the set point and a position of the second connector. The electronic processor receives, from the audio transducer, an audio signal during the time interval. The audio signal includes the sound generated when the coupling is formed. The electronic processor generates and analyzes the audio signal and identifies the sound of the coupling within the audio signal.
