  • Transient fault detection methods and systems
    Patent number: 9546604
    Abstract: The present disclosure provides methods, systems, and computer-readable media for the detection of valve faults based on transient air pressure measurements. For example, a method for fault detection may comprise actuating a shut off valve to an open position, determining a first air pressure of air in an enclosed space at a first time, determining a second air pressure of the air in the enclosed space at a second time and in response to actuation of the shut off valve to an open position, subtracting the first air pressure and the second air pressure to obtain an actual pressure difference, comparing the actual pressure difference to a predetermined pressure difference, and determining, based on the transient comparison, whether at least one of the shut off valve and a check valve is in a failed state.
