Distributed Remote-Controlled Sensor Network for Monitoring Complex Gas Environment Based on Intelligent Gas Analyzers

Abstract

The increasing complexity of modern industrial production and potential threats of chemical or biological pollution due to accidents, transport incidents or terrorist attacks require the continuous monitoring of changes occurring in complex gas mixtures to eliminate effects such changes in a timely fashion. To make adequate decisions ina short timeframe, it is necessary to have complete information about a wide range of potential xenobiotics within the monitoring area. In this study, such an important scientific and practical problem is solved by the formation of a network of e-nose intelligent analyzers based on a cross-reactive array of chemical sensors using piezoelectric elements of a quartz crystal microbalance (QCM) as physical transducers connected by means of telecommunication protocols. A distributed remote-controlled sensor network provides operational control of the perimeter of a protected and/or dangerous zone by monitoring the gaseous environment, and can be used for the control of technological processes, a security alarm forhigh-risk objects andthe generation of information about danger in order to prevent personnel from entering a workingarea with a potentially hazardous atmosphere.
