Title:
LINEAR FIRE-DETECTOR ALARMING SYSTEM BASED ON DATA FUSION AND THE METHOD
Document Type and Number:
WIPO Patent Application WO/2007/076642
Kind Code:
A1
Abstract:
A fire alarming method based on data fusion comprises steps of : using at least one
temperature sensor to detect and generate two nonequivalent values of the first
electric parameter and the second electric parameter at a certain moment; transmitting
the values of the two nonequivalent electric parameters detected at the moment
to an electrical signal measuring device; and calculating a function value at
this moment by a data fusing device according to a predetermined function which
includes at least the said first electric parameter and the said second electric
parameter; then comparing the obtained function value with a predetermined value;
determining whether a fire alarming signal is to be emitted according to the compared
result; if required, activating the fire alarming device. Also using two temperature
sensors to detect and generate two nonequivalent values of the first electric
parameter and the second electric parameter respectively is available. And
detecting successively two nonequivalent values of the first electric parameter
and the second electric parameter at two different moments is also available.
