FIRE DETECTING SYSTEM AND WEIGHT CORRECTING METHOD PERFORMED THEREBY
First Claim
1. A weight correcting method for a fire detecting system that includes a plurality of detectors configured for detecting a fire state, said weight correcting method comprising:
- a) setting weight values for the detectors, respectively;
b) setting a threshold value;
c) receiving a plurality of detecting values, each of which is obtained using a respective one of the detectors, wherein, for each of the detectors, the detecting value is equal to a first predetermined value when the fire state is detected thereby, and is equal to a second predetermined value when otherwise;
d) computing a summation of products of each of the detecting values and the weight value of the respective one of the detectors;
e) when the summation computed in step d) is greater than the threshold value, adding a first adjusting value to the weight value corresponding to the detector from which the detecting value equal to the first predetermined value is obtained, and adding a first correcting value to the weight value corresponding to the detector from which the detecting value equal to the second predetermined value is obtained; and
f) when the summation computed in step d) is smaller than the threshold value, adding a second correcting value to the weight value corresponding to the detector from which the detecting value equal to the first predetermined value is obtained, and adding a second adjusting value to the weight value corresponding to the detector from which the detecting value equal to the second predetermined value is obtained.

Abstract
A fire detecting system includes a plurality of detectors, and a computing unit coupled to the detectors. The detectors are configured for generating a plurality of detecting values, respectively. For each of the detectors, the detecting value is equal to a first predetermined value when a fire state is detected thereby, and is equal to a second predetermined value when otherwise. The computing unit sets a weight value for each of the detectors and a threshold value, and is configured to perform a weight correcting method for correcting the weight value of each of the detectors based on accuracy of operation of the detectors.
