Methods and systems for monitoring environments
First Claim
1. A system for monitoring a state of an environment, the state being defined by a plurality of measured parameters, the system comprising:
- a plurality of sensors distributed spatially within the environment, each such sensor being adapted to measure one of the measured parameters at its spatial location within the environment; and
a controller in communication with the sensors and having programming instructions to;
receive data collected from each of the sensors;
identify the occurrence of an event at at least one of the sensors by identifying a change in an event-defining parameter;
extract a plurality of derived parameters from the collected data;
determine a cross-correlation of the extracted plurality of derived parameters over the plurality of sensors; and
identify an abnormality in the environment from the determined cross-correlation.

Abstract
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.
