METHODS AND SYSTEMS FOR MONITORING ENVIRONMENTS

摘要

Methods and systems are provided for monitoring a state of an environment. Sensors are distributed spatially within the environment, with each sensor measuring one of the measured parameters at its spatial location. A controller receives data collected from each of the sensors. The controller identifies the occurrence of an event at at least one of the sensors. The controller extracts derived parameters from the collected data. The controller determines a cross-correlation of the extracted parameters over the sensors. The controller identifies an abnormality in the environment from the determined cross-correlation.
