Early fire detection arrangement - contains combination of sensors, microprocessor-controlled signal evaluation unit, fuzzy logic or neural network to avoid false alarms

摘要

The arrangement for the early detection of fires contains a combination of several sensors for different materials. The combination contains gas sensors and others, such as moisture of temperature sensors. An arrangement generates a gas with defined characteristics. A microprocessor-controlled signal evaluation unit is connected to the sensors and an alarm generator. The signal evaluation unit operates with fuzzy logic. The sensor signals can be processed in parallel by a neural network built in hardware or software form. USE/ADVANTAGE - Arrangement is improved to ensure reliable early detection of fires whilst preventing false alarms caused by tolerable gas and temperature triggering
