Development of device for identification explosions and fires

One of the key issues of security is fast and accurate analyses of different threats in above ground and underground structures of different applications. Among the most dangerous threats, that may end with fatal and destructive results are fires and explosions. Modern threat identification systems must be quick-acting and reliable. The development of contemporary detection devices is oriented to the creation of integrated systems ensuring monitoring of all possible threats as well as respective measures for threat prevention. A comprehensive security system enables identification of emergency and pre-emergency conditions and have WiFi modes of operation. This paper describes results of experimental investigations to identify and process information signals from different sources. The described works are necessary for designing the device integrated module of identification which is based on the constant monitoring on potential threat that may take place in manufacturing sites and tunnels. The potential threats discussed in the paper are: · Explosion, which is based on the monitoring of overpressure and methane concentration control in the media; · Fire, which identification is based on the monitoring of flame and smoke parameters. Besides the reliable identification and generation of the emergency signal, the proposed multifunctional device will ensure also the activation of the protective systems to reduce the damage and fatal consequences after explosion and/or fires.
