Early stage fire detecting apparatus |
| abstract |
An early stage fire detecting apparatus is arranged such that a fire state is discriminated based on a fire probability output from a signal processing network. The fire probability being prepared in such a manner that outputs from a high sensitivity smoke sensor SS and a smell sensor NS, from which responses can be obtained at the early stage of a fire, are subjected to signal processing. Fire information composed of a value at a given moment of smoke and a difference indicating the increase or decrease of the value at a given moment of the smoke and a value at a given moment of smell and a difference indicating the increase or decrease of the value at a given moment of the smell are input to the signal processing network. The signal processing network outputs the above fire probability based on a table (RAM12) defining a fire probability to be obtained from the above fire information and weighting values (RAM13). With this arrangement, an early stage fire can be detected by explicitly excluding non-fire factors such as tobacco, steam vapor, the smell of coffee, and the like. |
