Intelligent Fire Alarm System Based on MSA System

  • Received Date: 23 Mar 2007
  • Publish Date: 25 Aug 2007
    Abstract
  • An automatic fire alarm system based on MSA(multi-step-alarm) was proposed to overcome the shortcomings of a conventional fire alarm system composed of single type sensors.The proposed system integrates the signals from all fire alarm sensor by a multi-sensor data fusion system that is based on an BP neural network to reduce the possibility of failure for correct alarming.Criteria were presented to further confirm the alarm signals and to overcome the local optimum and oscillation in output of the BP neural network based solely on training.Experimental results show that,compared with the averaged results of 3 single type fire alarm sensors,the proposed system reduces false alarm by 80%,failure for alarming by 92%,and alarm time by 50%.
