Title: A METHOD OF MONITORING A PREDETERMINED TYPE OF MOLECULE CONVEYED THROUGH A GASEOUS MEDIUM
Abstract:
One or more detectors, such as an electronic nose, are positioned for sensing a predetermined type of molecule in a gaseous medium, (eg, an organic odour or pollutant emitted from a processing plant). Data from the detectors may be transmitted by wireless, internet, or other means, and is electronically processed. Data may be classified via data clustering software (48, 55) using, for example, k-means cluster analysis. An artificial neural network may be trained to predict probable future data on the basis of earlier data (52, 54, 55), including, for example, whether the future concentration level of the predetermined type of molecule will be above a threshold level. The processed data may be used to generate an alarm signal and/or a feedback signal, to allow the source of the predetermined type of molecule to be manually or automatically controlled.
