Cloud Based Adaptive Learning for Distributed Sensors

摘要

A low power sound recognition sensor is configured to receive an analog signal that may contain a signature sound. Sound parameter information is extracted from the analog signal and compared to a sound parameter reference stored locally with the sound recognition sensor to detect when the signature sound is received in the analog signal. A trigger signal is generated when a signature sound is detected. A portion of the extracted sound parameter information is sent to a remote training location for adaptive training when a signature sound detection error occurs. An updated sound parameter reference from the remote training location is received in response to the adaptive training.

1. A method for operating a sound recognition sensor, the method comprising:
receiving an analog signal that may contain a signature sound; extracting sound parameter information from the analog signal; comparing the sound parameter information to a sound parameter reference stored locally with the sound recognition sensor to detect when the signature sound is received in the analog signal; generating a trigger signal when a signature sound is detected; sending a portion of the extracted sound parameter information to a remote training location for adaptive training when a signature sound detection error occurs; and receiving an updated sound parameter reference from the remote training location in response to the adaptive training.
