Abstract

A fire monitoring system detects a plurality of types of detection information using a plurality of fire phenomenon detectors for detecting physical quantities caused by fire phenomena or using a plurality of detectors each including at least one fire phenomenon detector and at least one environment detector provided in association with the fire phenomenon detector. The plurality of types of detection information undergo consolidated signal processing for obtaining one or more types of fire information for realizing fire monitoring. The fire monitoring system includes a table for storing a specific set of values one for each type of detection information and a corresponding set of values for each type of fire information to be obtained when the specific set of values of detection information is supplied, and a signal processing net having a multilayer structure responsive to the input of respective values for the types of detection information to thereby impart corresponding weights to each value of the input detection information in accordance with the degree of contribution thereof to each value of fire information and to arithmetically determine each value of fire information on the basis of the weighted detection information values. In a learning mode, the weights are adjusted that a value for each type of fire information determined arithmetically when the specific set of values of detection information placed in the table is supplied to the signal processing net approximates the value for each type of fire information contained in the table.
