  • Publication number: 20250137822
    Abstract: A multiple sensor-based abnormal condition monitoring method includes determining an operation mode based on condition information in a target area in which an abnormal condition is monitored, receiving sensing signals from a plurality of sensors installed in the target area in response to a first mode in which different objects are simultaneously detected being determined as the operation mode, processing the sensing signals and outputting first sensing data obtained by converting the sensing signals into digital signals, generating first input data to be input to a first neural network model by variably adjusting a size of the first sensing data, performing an operation in an analog domain on the first input data using the first neural network mode and outputting first operation data obtained by converting an operation result into digital data, and outputting a first monitoring result obtained by classifying an abnormal condition based on the first operation data.
