Patent ID: 8203456

Claim:
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.
