- Abstract
- [Abstract in English] Signals of fire sensors always have their steady state values. In the fire case, the signal trends are special because of the steady state value. In this paper, a detector for the special trend is proposed. One adaptive window has been used for the trend calculation in this detector. When the detector finds a trend, the window can be extended step by step automatically, in order to reduce false alarms. The detector has been tested by different signals with a simulating program. The tested results show that the detector can discover the standard test fires in time and has a very low false alarm rate.
