Abstract
PURPOSE:To eliminate the hourly fluctuation of a vector locus and to correctly judge a fire by judging the fire based on a vector obtained by a center-of-gravity processing. CONSTITUTION:A data sampling part 4 executes the sampling of detecting data from sensors 1a-1n transmitted by transmitters 2a-2n at every prescribed sampling synchronization, and the position vector of an (n) dimensional space is calculated based on (n) kinds of sensor data. The center-of-gravity processing is executed plural times, the position vector at a time (t) obtained by a center-of- gravity operation 5 and a closed curved surface to give a dangerous level set beforehand at a closed curved surface setting part 7 are compared 6, and when the position vector is at the outside of the closed curved surface, an alarm signal is outputted.
